     TECHNICAL FIELD 
     The present invention relates to a composition for promoting collagen production which comprising one or more compounds selected from the group consisting of D-aspartic acid, D-alanine, derivatives and/or salts thereof, and a method of suppressing and/or improving a skin condition comprising a step of administering the compound. 
     BACKGROUND ART 
     Type I collagen is one of the major skin proteins and it is a triple helix protein composed of two strands of α(alpha)1 (I) chain and one strand of α(alpha) 2 (I) chain. Type I collagen is produced by fibroblasts in the skin dermis and it forms an extracellular matrix in which the fibroblasts are embedded. Both intrinsic aging and photoaging are accompanied with reduced collagen production and increased activity of collagenase (Non-Patent Documents 1 to 3). Thus, it has been believed that a promotion of collagen production leads to suppression and/or improvement of a skin condition caused by intrinsic aging or photoaging, for example, wrinkle formation. In fact, it is known that retinoids, i.e., derivatives of vitamin A, have an efficacy when applied to the face or upper arm skin caused by intrinsic aging or photoaging (Non-Patent Documents 4 and 5). However, the retinoids have a side effect like photosensitization or inflammatory reaction known as a retinoid reaction (Non-Patent Document 6). Further, having generally high photoreactivity, the retinoids need to be protected from light for stable storage. Thus, after administration to the skin, the retinoids may be easily decomposed by light penetrating a living body under ordinary living conditions.

     Problem to be Solved by the Invention 
     Under the circumstances, there is a need to develop a novel composition which has an effect on promoting collagen production, specifically a composition which has high photostability and is free from side effects such as those of retinoids. 
     Means for Solving the Problem

     The composition for promoting collagen production of the present invention may be used for a food. 
     The composition for promoting collagen production of the present invention may be a composition for promoting type I collagen production. 
     The present invention also provides a method of suppressing and/or improving a skin condition comprising a step of administering a composition for promoting collagen production comprising one or more compounds selected from the group consisting of D-aspartic acid, D-alanine, derivatives and/or salts thereof. 
     The skin condition that is suppressed and/or improved by the method of the present invention comprises photoaging and/or wrinkles, but not limited thereto. 
     Regarding the method of the present invention, the composition for promoting collagen production of the present invention may be used for an external preparation for the skin. 
     Regarding the method of the present invention, the composition for promoting collagen production of the present invention may be used for a food composition. 
     According to the Method of the present invention, the composition for promoting collagen production may be a composition for promoting type I collagen production. 
     As used herein, the term “salt” of D-aspartic acid and D-alanine indicates any salts comprising a metal salt and an amine salt or the like, provided that the effect on promoting collagen production of D-aspartic acid and D-alanine is not impaired. The metal salts may comprise an alkaline metal salt, an alkaline earth metal salt and the like. The amine salts may comprise a triethylamine salt, a benzylamine salt and the like. 
     As used herein, the term “derivatives” of D-aspartic acid and D-alanine indicates D-aspartic acid and D-alanine molecules that are covalently bound to any atomic group via their amino groups, carboxyl groups, or side chains, provided that the effect on promoting collagen production of D-aspartic acid and D-alanine is not impaired. The atomic group includes, but is not limited to, protective groups, such as N-phenylacetyl group, and 4,4′-dimethoxytrityl (DMT) group; biopolymers, such as a protein, a peptide, a saccharide, a lipid, and a nucleic acid; synthetic polymers, such as a polystyrene, a polyethylene, a polyvinyl, and a polyester; and functional groups such as an ester group. The ester group may comprise, for example, an aliphatic ester, such as methyl ester, and ethyl ester; and an aromatic ester. 
     An amino acid has optical isomers which are the L-form and D-form. A natural protein has L-amino acids bound by peptide bonds and only L-amino acids are employed excluding some exceptions such as a bacterial cell wall. Therefore, it has been considered that in a mammal including a human only L-amino acids are present and only L-amino acids are utilized (Kinouchi, T. et al., TANPAKUSHITSU KAKUSAN KOSO (PROTEIN, NUCLEIC ACID AND ENZYME), 50:453-460 (2005), Lehninger Principles of Biochemistry [Vol. 1] 2nd ed., pp 132-147 (1993), Japanese-language translation, Hirokawa Shoten Ltd., Harper&#39;s Biochemistry, Original version, 22nd ed., pp 21-30 (1991), Japanese-language translation Maruzen Co., Ltd.). Accordingly, only L-amino acids have been mostly employed as amino acids academically and industrially for a long time. 
     Exceptional cases where a D-amino acid is employed are, for example, a case of using as a raw material for an antibiotics produced by a microorganism, and, a case of a food additive employing a D-amino acid in a DL-amino acid mixture for the purpose of reducing cost of fractionating only an L-amino acid from a mixture of the L- and D-amino acids, which are obtained in equimolar amounts by synthesizing the amino acids. Nevertheless, there has been no case of using only a D-amino acid not including an L-amino acid industrially as a physiologically active substance. 
     D-serine and D-aspartic acid have high ratio of D-form, and therefore many studies have been made compared to other amino acids. D-serine is localized in the cerebrum and the hippocampus, and it is known as a regulatory factor for the NMDA receptor in the brain. D-aspartic acid is found to be localized in the testis and pineal body, and it is known to be involved in the control of hormone secretion (Japanese Patent Unexamined Publication No. 2005-3558). However, the physiological activities of D-aspartic acid and D-alanine in the skin are not clearly defined. 
     As illustrated in the following examples, the effect on promoting collagen production of D-aspartic acid and D-alanine has been unknown so far. Thus, the composition for promoting collagen production of the present invention comprising D-aspartic acid and/or D-alanine is a novel invention. 
     Recently, it was reported that ddY mice were allowed to ingest freely a 10 mM aqueous solution of a D-amino acid for two weeks and then examined for the D-amino acid concentration in each organ, which was 3 to 1000 pmol per gland in the pineal body and 2 to 500 nmol per wet gram in the brain tissue (Morikawa, A. et al., Amino Acids, 32:13-20 (2007)). Based on the above, the lower limit for daily intake amount of D-aspartic acid and D-alanine contained in the composition of the present invention is calculated as described below. 
     The D-aspartic acid of the present invention has an effect on promoting collagen production in cultured human fibroblasts within the concentration range of 0.01 μM (micro-molar) to 320 μM (micro-molar), as described in the following Examples. Thus, the amount of the D-aspartic acid that is contained in the composition of the present invention may be any content, provided that the D-aspartic acid in the above concentration range is delivered to fibroblasts in the skin tissue in vivo. As for an external preparation for the skin of the present invention, the content of D-aspartic acid may be 0.0000001% by weight to 50% by weight, or up to the maximum weight concentration that can be formulated, in the total composition of the invention. Specifically, when the composition is an external preparation for the skin, the content of D-aspartic acid is preferably 0.000001% by weight to 30% by weight, and the most preferably 0.00001% by weight to 3% by weight. When the composition of the present invention is an internal agent, the content of D-aspartic acid may be within the range of 0.0000001% by weight to 100% by weight. When the composition of the present invention is an internal agent, the content of the D-aspartic acid is preferably 0.0000002% by weight to 80% by weight and the most preferably 0.000001% by weight to 60% by weight. Further, the lower limit of a daily intake amount of D-aspartic acid that is contained in the composition of the present invention may be 0.01 ng, preferably 0.1 ng, and more preferably 1 ng per 1 kg of body weight. 
     As illustrated in the following examples, within the concentration range of from 0.01 μM (micro-molar) to 1000 μM (micro-molar), D-alanine of the present invention has an effect on promoting collagen production in cultured human fibroblasts. As such, the amount of D-alanine contained in the skin condition improving agent, an external preparation for the skin, and the food composition of the present invention can have any amount, provided that the D-alanine within the above concentration range is delivered to fibroblasts in the skin tissue in vivo. As for an external preparation for the skin of the present invention, the content of D-alanine may be from 0.000001% by weight to 50% by weight, or up to the maximum weight concentration that can be formulated, in the total composition of the invention. Specifically, when the composition is an external preparation for the skin, the content of D-alanine is preferably 0.00001% by weight to 30% by weight, and the most preferably 0.0001% by weight to 10% by weight. When the composition of the present invention is an internal agent, the content of D-alanine may be within the range of 0.000001% by weight to 100% by weight. When the composition of the present invention is an internal agent, the content of D-alanine is preferably 0.00001% by weight to 80% by weight and the most preferably 0.0001% by weight to 60% by weight. Further, the lower limit of a daily intake amount of D-alanine that is contained in the composition of the present invention may be 0.01 ng, preferably 0.1 ng, and more preferably 1 ng per 1 kg of body weight. 
     The composition of the present invention may further comprise one or more pharmaceutically acceptable additives, in addition to the group of D-aspartic acid, D-alanine, salts of D-aspartic acid and D-alanine and/or derivatives of D-aspartic acid and D-alanine capable of releasing D-aspartic acid and D-alanine by a drug metabolizing enzyme and the like in vivo, provided that the effect on promoting collagen production of D-aspartic acid and D-alanine is not impaired. Such additives comprise, but are not limited to, a diluent and an extender, a binder and an adhesive, a lubricant, a glidant, a plasticizer, a disintegrant, a carrier solvent, a buffering agent, a colorant, a flavoring agent, a sweetener, a preservative and a stabilizer, an adsorbent, as well as other pharmaceutical additives known to those skilled in the art. 
     The composition of the present invention may be prepared by using, as an active component, only D-aspartic acid, D-alanine, salts of D-aspartic acid and D-alanine and/or derivatives of D-aspartic acid and D-alanine capable of releasing D-aspartic acid and D-alanine by a drug metabolizing enzyme and the like in vivo. However, within the range that the effect of the present invention is not impaired, it may be appropriately formulated with other components that are used for an external preparation for the skin like cosmetics comprising quasi drugs and pharmaceutical products, if necessary. Examples of other components (i.e., optionally formulated components) comprise an oil, a surface active agent, a powder, a colorant, water, alcohols, a thickening agent, a chelating agent, silicones, an antioxidant, an UV absorbing agent, a moisturizing agent, a flavoring agent, various pharmaceutically active ingredients, a preservative, a pH adjusting agent, and a neutralizing agent. 
     A dosage form of a composition of promoting collagen production of the present invention that is used for suppressing and/or improving a skin condition (herein below, referred to as an “agent for improving skin condition”) may be any one that is commonly used for quasi drug compositions and pharmaceutical compositions comprising an external preparation for the skin like an ointment, a cream, an emulsion, a lotion, a pack, gel, and a patch, an oral preparation like powder, granules, a soft capsule, and a tablet, a pernasal preparation like a nasal spray, and an injection solution. 
     A dosage form of the external preparation for the skin according to the present invention is not specifically limited, provided that it is conventionally used for an external preparation for the skin, and it comprises an ointment, a cream, an emulsion, a lotion, a pack, a gel, and a patch. 
     The food composition of the present invention may further comprise, in addition to D-aspartic acid, D-alanine, salts of D-aspartic acid and D-alanine and/or derivatives of D-aspartic acid and D-alanine capable of releasing D-aspartic acid and D-alanine by a drug metabolizing enzyme and the like in vivo, a seasoning, a colorant, a preservative, and other components that can be used for a food product, provided that the effect on promoting collagen production by D-aspartic acid and D-alanine is not impaired. 
     The food composition of the present invention may be any one employed conventionally as a food composition comprising, but not limited to, a candy, a cookie, bean paste, a French dressing, a mayonnaise, a French bread, a soy sauce, yogurt, dried seasoning powder for rice, seasoning/sauce for natto (Japanese fermented soybean), natto, unrefined black vinegar.

     DESCRIPTION OF EMBODIMENTS 
     Examples of the present invention described below are intended only to exemplify the present invention rather than to limit the technical scope thereof. The technical scope of the present invention is limited only by the descriptions in the claims. 
     All references cited herein are incorporated by reference in its entirety. 
     Example 1 
     Collagen Production Promoting Effect of D-Aspartic Acid Methods 
     Cell Culture 
     Commercially available human neonatal dermal fibroblasts (Cryo NHDF-Neo, manufactured by Sanko Junyaku Co., Ltd.) were used. The cells were inoculated in a commercially available 24-well plate to have 2×10 5  cells per well. The cells were then cultured for four hours in a commercially available medium for cell culture (D-MEM (1 g/L glucose), manufactured by Wako Pure Chemical Industries, Ltd.) to which 10% bovine fetal serum was supplemented (herein below, referred to as a “standard medium”) in a 5% CO 2  and saturated water vapor atmosphere at 37° C. (degrees Celsius). 
     Addition of Amino Acids 
     Subsequently, the medium was switched to a commercially available medium for cell culture (D-MEM (1 g/L glucose), manufactured by Wako Pure Chemical Industries, Ltd.) supplemented with 0.5% bovine fetal serum (herein below, referred to as “low-serum medium”) and cultured for approximately one day in a 5% CO 2  and saturated water vapor atmosphere at 37° C. (degrees Celsius). D-aspartic acid (manufactured by Wako Pure Chemical Industries, Ltd., 018-04821) was added to the low-serum medium to have the concentration of 0.01 μM (micro-molar), 0.1 μM (micro-molar), μM (micro-molar), 100 μM (micro-molar), or 320 μM (micro-molar). As a positive control, magnesium L-ascorbyl phosphate (L-Ascorbic Acid Phosphate Magnesium Salt n-Hydrate, herein below, referred to as “APM”, manufactured by Wako Pure Chemical Industries, Ltd., 013-19641) was added to the low-serum medium to have the concentration of 150 μM (micro-molar), 250 μM (micro-molar), or 500 μM (micro-molar). Further, the low-serum medium described above to which neither APM nor D-aspartic acid had been added was employed as a negative control. 
     Quantification of Production Amount of Type I Collagen 
     After completing the cell culture for two days, the culture supernatant was collected and the concentration of C-terminal peptide of type I procollagen (herein below, referred to as “PIP”) produced by human neonatal dermal fibroblasts was measured by using Procollagen type I C-peptide EIA kit (manufactured by Takara Bio Inc.) according to the manufacturer&#39;s instruction. 
     Quantification Results 
       FIG. 1  shows the results of the experiment examining the effect of adding D-aspartic acid on type I collagen production in human neonatal dermal fibroblasts. The error bars for each experimental condition indicate the standard deviations of the experimentally measured values obtained by repeating the experiment four to six times under the identical condition. Further, the double asterisk (**) indicates that p is less than 1% by Bonferroni/Dunn test. 
     The PIP concentration was 583 ng/mL in the negative control. When APM had been added at the concentration of 150 μM (micro-molar), 250 μM (micro-molar), and 500 μM (micro-molar) (i.e., positive controls), the PIP concentrations were increased to 1183 ng/mL, 1666 ng/mL, and 1416 ng/mL, respectively. When D-aspartic acid had been added at the concentrations of 0.01 μM (micro-molar), 0.1 μM (micro-molar), 10 μM (micro-molar), 100 μM (micro-molar), and 320 μM (micro-molar), the PIP concentrations were 1286 ng/mL, 1159 ng/mL, 1117 ng/mL, 1119 ng/mL, and 1007 ng/mL, respectively. Thus, compared to the negative control, the medium added with APM or D-aspartic acid showed the statistically significant effect on promoting type I collagen production under the every concentration condition. Further, the effect on promoting type I collagen production of D-aspartic acid at the concentrations of 0.01 μM (micro-molar) to 100 μM (micro-molar) was similar to the effect obtained by using APM at the lowest concentration, i.e., 150 μM (micro-molar), and therefore, it was found that D-aspartic acid had prominently more potent effect on promoting type I collagen production than APM. 
     Example 2 
     Effect of Promoting Collagen Production of D-Alanine Methods 
     The cell culture, addition of amino acids, and quantification of production amount of type I collagen were carried out in the same manner as the Example 1. As an amino acid, D-alanine (manufactured by Peptide Institute, Inc., 2801) was used at the concentrations of 0.01 μM (micro-molar), 0.1 μM (micro-molar), 10 μM (micro-molar), 1000 μM (micro-molar), and 17400 μM (micro-molar). Further, the low-serum medium described above to which neither APM nor D-alanine had been added was employed as a negative control. 
     Quantification Results 
       FIG. 2  shows the results of experiment examining the effect of adding D-alanine on type I collagen production in human neonatal dermal fibroblasts. The error bars for each experimental condition indicate the standard deviations of experimentally measured values obtained by repeating the experiment four to six times under the identical condition. The asterisk (*) indicates that p is less than 5% by Bonferroni/Dunn test. The double asterisk (**) indicates that p is less than 1% by Bonferroni/Dunn test. 
     The PIP concentration was 551 ng/mL in the negative control. When APM had been added at the concentrations of 150 μM (micro-molar), 250 μM (micro-molar), and 500 μM (micro-molar) (i.e., positive controls), the PIP concentrations were increased to 1183 ng/mL, 1666 ng/mL, and 1416 ng/mL, respectively, illustrating promoted production of type I collagen. When D-alanine had been added at the concentrations of 0.01 μM (micro-molar), 0.1 μM (micro-molar), 10 μM (micro-molar), 1000 μM (micro-molar), and 17400 μM (micro-molar), the PIP concentrations were 750 ng/mL, 789 ng/mL, 876 ng/mL, 823 ng/mL, and 799 ng/mL, respectively. Thus, compared to the negative control, the medium added with APM or D-alanine illustrated the statistically significant effect on promoting type I collagen production under the every concentration condition. 
     Example 3 
     Effect on Promoting Collagen Production of L- and D-Aspartic Acid 
     Methods 
     The cell culture, addition of amino acids, and quantification of production amount of type I collagen were carried out in the same manner as the Example 1. D-Aspartic acid (manufactured by Wako Pure Chemical Industries, Ltd., 018-04821) of 0.1 μM (micro-molar) and L-aspartic acid (manufactured by Wako Pure Chemical Industries, Ltd., 013-04832) of 0.1 μM (micro-molar) were used as amino acids. Further, the low-serum medium described above to which neither L-aspartic acid nor D-aspartic acid had been added was employed as a negative control. 
     Quantification Results 
       FIG. 3  shows the results of experiment examining the effect of adding L- and D-aspartic acid on the type I collagen production in human neonatal dermal fibroblasts. The error bars for each experimental condition indicate the standard deviations of experimentally measured values obtained by repeating the experiment six to twelve times under the identical condition. The double asterisk (**) indicates that p is less than 1% by Bonferroni/Dunn test. 
     The PIP concentration was 361 ng/mL in the negative control. When L-aspartic acid and D-aspartic acid had been at the concentration of 0.1 μM (micro-molar), the PIP concentration was 406 ng/mL and 456 ng/mL, respectively. Based on these results, it was found that production of type I collagen was promoted with statistical significance by addition of 0.1 μM (micro-molar) D-aspartic acid, but not by addition of 0.1 μM (micro-molar) L-aspartic acid. 
     Example 4 
     Effect on Promoting Collagen Production of L- and D-Alanine 
     Methods 
     The cell culture, addition of amino acids, and quantification of production amount of type I collagen were carried out in the same manner as the Example 1. D-Alanine (manufactured by Peptide Institute, Inc., 2801) of 0.1 μM (micro-molar) or 150 μM (micro-molar) and L-alanine (manufactured by Peptide Institute, Inc., 2701) of 0.1 μM (micro-molar) or 150 μM (micro-molar) were used as amino acids. Further, the low-serum medium described above to which neither L-alanine nor D-alanine had been added was employed as a negative control. 
     Quantification Results 
       FIG. 4  shows the results of experiment examining the effect of adding L- and D-alanine on the type I collagen production in human neonatal dermal fibroblasts. The error bars for each experimental condition indicate the standard deviations of experimentally measured values obtained by repeating the experiment six to twelve times under the identical condition. The asterisk (*) and double asterisk (**) indicate that p is less than 5% and less than 1%, respectively, by Bonferroni/Dunn test. 
     The PIP concentration was 361 ng/mL in the negative control. When D-alanine had been added at the concentrations of 0.1 μM (micro-molar) and 150 μM (micro-molar), the PIP concentrations were 502 ng/mL and 450 ng/mL, respectively. When L-alanine had been added at the concentrations of 0.1 μM (micro-molar) and 150 μM (micro-molar), the PIP concentrations were 405 ng/mL and 413 ng/mL, respectively. Based on these results, it was found that the production of type I collagen was promoted with statistical significance by addition of 0.1 μM (micro-molar) or 150 μM (micro-molar) D-alanine, but not by addition of 0.1 μM (micro-molar) or 150 μM (micro-molar) L-alanine. 
     Example 5 
     Effect on Promoting Collagen Production of D-Aspartic Acid and D-Alanine 
     Methods 
     The cell culture and addition of amino acids were carried out in the same manner as the Example 1. D-Aspartic acid (manufactured by Wako Pure Chemical Industries, Ltd., 018-04821) of 0.1 μM (micro-molar) and D-alanine (manufactured by Peptide Institute, Inc., 2801) of 0.1 μM (micro-molar) or 0.001 μM (micro-molar) were used as amino acids. Further, the low-serum medium described above to which neither D-aspartic acid nor D-alanine had been added was employed as a negative control. As a positive control, APM was added to the low-serum medium described above to have the concentration of 250 μM (micro-molar). In order to evaluate the production amount of type I collagen, type I procollagen and tropocollagen produced by human neonatal dermal fibroblasts were treated with pepsin (800 to 2500 unit/mg, P7000, manufactured by SIGMA), and the concentration of type I atelocollagen was measured by type I human collagen ELISA (EC1-E105, manufactured by AC Biotechnologies) according to the manufacturer&#39;s instruction. 
     Quantification Results (1) 
       FIG. 5  shows the results of experiment examining the effect of adding D-aspartic acid and D-alanine on type I atelocollagen production in human neonatal dermal fibroblasts. The error bars for each experimental condition indicate the standard deviations of experimentally measured values obtained by repeating the experiment five to six times under the identical condition. The asterisk (*) and double asterisk (**) indicate that p is less than 5% and less than 1%, respectively, by Bonferroni/Dunn test. 
     The concentration of type I atelocollagen was 1.8 μg (microgram)/mL in the negative control. When APM had been added at the concentration of 250 mM (i.e., positive control), the concentration of type I atelocollagen was increased to 3.9 μg (microgram)/mL, exhibiting the promoted production of type I collagen. When D-alanine had been added at the concentration of 0.1 μM (micro-molar), the concentration of type I atelocollagen was 4.0 μg (microgram)/mL. When D-aspartic acid had been added at the concentration of 0.1 μM (micro-molar), the concentration of type I atelocollagen was 3.8 μg (microgram)/mL. Based on these results, it was found that the production of type I collagen was promoted with statistical significance by addition of 0.1 μM (micro-molar) D-aspartic acid or D-alanine.

     Method for Producing Formulation Example 14 (Bean Paste) 
     Malted rice is mixed thoroughly with a salt. Washed soybeans are soaked overnight in three times its volumes of water, which are then drained off, and new water is added while boiling, and poured into a colander to collect the broth (tanemizu fluid), to which D-aspartic acid and/or D-alanine are dissolved at 10% w/v. The boiled beans are minced immediately, combined with malted rice mixed with salt, to which the tanemizu fluid containing D-aspartic acid and/or D-alanine dissolved therein is added and kneaded evenly to obtain a clay-like hardness. Dumplings are made and stuffed in a container compactly without forming any voids, and the surface of the content is smoothened and sealed with a plastic film. After three months, the content is transferred to a new container and the surface is smoothened and sealed with a plastic film. Instead of adding D-aspartic acid and/or D-alanine to the tanemizu fluid, malted rice producing a large amount of D-aspartic acid and/or D-alanine may be employed. Such malted rice can be selected by quantifying D-aspartic acid and/or D-alanine by the method described in Japanese Patent Unexamined Publication No. 2008-185558. Alternatively, a commercially available bean paste can be supplemented with D-aspartic acid and/or D-alanine or a salt thereof.

     Method for Producing Formulation Example 19 and 20 (French Bread) 
     Lukewarm water is combined with 1 g of sugar and dry yeast, which is then allowed to undergo a pre-fermentation. Hard flour, weak flour, sodium chloride, 5 g of sugar, and D-aspartic acid or D-alanine are placed in a bowl, into which the pre-fermented yeast is placed. After kneading thoroughly into a ball-like dough, a primary fermentation is conducted at 30° C. (degrees Celsius). The dough is kneaded again and allowed to stand, and then shaped into suitable forms, which are subjected to a final fermentation using an electronic fermentation machine. After forming coupes, baking is conducted for 30 minutes in an oven at 220° C. (degrees Celsius).

     Commercially available soy sauce is supplemented with D-aspartic acid or D-alanine, and stirred thoroughly. Instead of adding D-aspartic acid or D-alanine, or a salt thereof, malted rice producing a large amount of D-aspartic acid or D-alanine may be employed for fermenting soy sauce. Such malted rice can be selected by quantifying D-aspartic acid or D-alanine by the method described in Japanese Patent Unexamined Publication No. 2008-185558.

     Fermentation is conducted at 40 to 45° C. (degrees Celsius). Other commercially available fermentation seed organisms may be employed and commercially available yogurt may be supplemented with D-aspartic acid or D-alanine. Instead of adding D-aspartic acid or D-alanine, or a salt thereof, a seed organism producing a large amount of D-aspartic acid or D-alanine may be employed. Such an organism can be selected by quantifying D-aspartic acid or D-alanine by the method described in Japanese Patent Unexamined Publication No. 2008-185558.
