title: Determination of the Quality and Shelf Life of Sous Vide Cooked Turkey Cutlet Stored at 4 and 12ºC

description: ABSTRACT The aim of this study was to determine the quality and shelf life of sous vide turkey cutlet stored at 4 and 12ºC. Samples were packaged under vacuum into polyamide-polypropylene pouches, cooked using sous vide technology (65ºC/40 min), chilled at 3ºC and stored at 4 and 12ºC for 5 weeks. Microbial (TMAB, lactic acid bacteria, Enterobacteriaceae, moulds and yeasts, Salmonella spp., L. monocytogenes, Cl. perfringens), physical-chemical (pH, water activity, TBARS, L*a*b* colour, texture profile analysis and shear force) and sensory (appearance, colour, odour, flavour, juiciness, chewiness and acceptance) parameters were determined. According to the results of mesophilic bacterial counts and sensory analysis, the shelf life of the sous vide turkey cutlet, cooked at 65ºC for 40 min, was determined as 28 days at 4ºC while 15 days at 12ºC. Salmonella spp., L. monocytogenes, Cl. perfringens were not detected in turkey cutlet samples during the storage period. It was detected that sous vide cooked provided convenient ready-to-eat foods and a long shelf life for turkey cutlet.

title: Standard Body Weight and Serum Estradiol and Progesterone Concentrations in Response to Total Lysine Content in Female Broiler Breeders from 14 to 42 Days after Hatch

description: ABSTRACT This study was conducted to determine the total lysine requirement for female broiler breeders from days 14 to 42. Two-hundred and ten female broiler breeders were used in a completely randomized design with 6 replicates per treatment and 5 chicks per pen under restricted feeding. The contents of total lysine used in this experiment were 0.68, 0.72, 0.76, 0.80, 0.84, 0.88 and 0.92% in the diet. A basal diet was formulated to meet or to exceed the Ross 308 female broiler breeders’ nutrient specifications except for the lysine. Body weight and feed intake were measured to calculate feed efficiency, and body weight uniformity was defined on a weekly basis. One chick per pen was randomly selected to collect blood samples, organ and an abundance of sexual maturity associated miRNAs (miR-21, mi-26a and mi-375) in the plasma was measured on day 42. Increasing total lysine contents in the diet improved body weight gain and feed conversion ratio from days 14 to 42. The combined values from the two models for BW, average daily gain and feed efficiency were estimated at 1.04, 1.00 and 1.21% total lysine, respectively. Total lysine contents did not affect the ovary weight, serum estradiol-17b, serum progesterone and plasma urea nitrogen or the expression levels of the three miRNAs on day 42. Therefore, the results from the current study indicated that female broiler breeders fed on 0.68% total lysine could achieve the recommended BW, suggested by field practice when data were fitted into the overlapped point of linear-, and quadratic-plateau models.

title: Effects of Light Intensity on Growth, Anti-Stress Ability and Immune Function in Yellow Feathered Broilers

description: ABSTRACT An experiment was conducted to investigate the effects of light intensity on growth, anti-stress ability, and immune function of yellow feathered broilers. A total of 480 one-day-old male Lingnan yellow feathered broilers were randomly allocated to 4 treatments based on light intensity (1, 5, 20 and 80 lx) with 8 replicates of 15 chicks each. The experiment lasted for 63 days. Compared with those under high light intensity, broilers exposed to low light intensity had higher (p&lt;0.05) total antioxidant capacity (T-AOC), glutathione peroxidase (GSH-Px), a-Naphthylacetate esterase (ANAE+), antibody titer, but lower (p&lt;0.05) malonaldehyde (MDA) levels and heterophil/lymphocyte ratio (H/L). There was a linear effect for T-AOC(p=0.002), GSH-Px(p≤0.047), MDA (p=0.003), H/L(p≤0.014), ANAE+ (p≤0.044), and antibody titer (p≤0.021) with T-AOC, GSH-Px, ANAE+, and antibody titer increased significantly as light intensity decreased, whereas MDA and H/L were decreased with the decrease in light intensity. These results suggested that broilers under low light intensity could have similar performance, better anti-stress ability, stronger immune function, and more efficient in energy usage as compared with those exposed to high light intensity environment.

title: The Effect of Dietary Tarragon (Artemisia Dracunculus) Powders in Different Levels on Carcass Characteristics and Some Internal Organ’s Weight of Broiler Chickens

description: ABSTRACT This study was conducted to investigate the effects of different levels of Tarragon powder on head, chicken feet, some internal organs and carcass characteristics of broiler chickens. One day -old two hundred forty Ross 308 male broilers were randomly allocated into four treatments and six replicates per treatment. At each replicate ten birds were used. All birds at 42 days had ad libitum access to water and feed and were exposed to a 23L:1D lighting program. The diets were set on the basis of corn, soybean and wheat meal, formulated according to the recommendations of the Ross 308 manual (starter days 1-14, grower days 15-37, and finisher days 38-42), and offered as mash. The tarragon plant used in the research was purchased from a vegetable market in Erzurum province in Turkey. Treatments were: base diet (Control), base diet + 0.1% of Tarragon powder (group A), base diet + 0.2% of Tarragon powder (group B), base diet + 0.5% of Tarragon powder (group C). Except for relative wing and head weight, other carcass traits were not significantly affected (p&gt;0.05) by different levels of Tarragon powder. The lowest relative head weight (p&lt;0.001), and the highest relative wing weight (p&lt;0.05) were observed in the control group. The results of this study suggest that the addition of Tarragon powder to broiler diets has no effect on other important carcass traits, except for the head and wing weights of broiler chickens.

title: Storage stability of sweet biscuit elaborated with recovered potato starch from effluent of fries industry

description: Abstract The effluent from the potato chips processing could be recovered and used in the biscuit formulations. This study aimed to evaluate the changes of sweet biscuits with partial replacement (45%) of wheat flour by recovered potato starch, packed in biaxial oriented polypropylene (BOPP), and stored under two controlled temperatures (25°C and 35°C). The changes of physical, chemical, microbiological and sensory characteristics of biscuits were evaluated for 6 months. Completely randomized design with 2x6 factorial arrangement was employed. In the first 36 days of biscuits storage was no increase in water activity and this remained constant up to 144 days of storage, up next. The score for sensory texture reduced over time, which shows that the tasters preferred less hard biscuits, since there was an increasing trend of instrumental hardness during storage, probably due to starch retrogradation, facilitated by higher moisture biscuits. Sweet biscuits of wheat flour and potato starch acidified and dehydrated have good physical and microbiological conditions, being able to be consumed for a period of 180 days. Potato starch recovered after acidified and dehydrated can be used as an ingredient in the products development for human consumption, avoiding losses and environmental pollution, and to generate economic gains.

title: Evaluation of antioxidant activities, total phenolic content (TPC), and total catechin content (TCC) of 10 sugar apple (Annona squamosa L.) cultivar peels grown in Thailand

description: Abstract Antioxidant activities, total phenolic content (TPC), and total catechin content were analyzed in the ethanol extracts of 10 sugar apple (Annona squamosa L.) cultivar peels grown in Thailand. Antioxidant activity assays carried out in the this study were the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, ferric ion reducing antioxidant power (FRAP), 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical cation scavenging activity, and oxygen radical absorbance activity (ORAC). ‘Nhur Thong’, ‘Nung Keaw’, and ‘Fai Keaw’ showed high percentage fruit peel (over 38.0%). ‘Nhur Thong’, ‘Nung Keaw’, and ‘Fai Keaw’ ethanol extracts possessed high antioxidant capacities in the majority of methods used, and thus could be potential candidate of natural antioxidants. ‘Fai Keaw’ showed the best activity in the ABTS (1.57 mmol of trolox/g dry sample), FRAP (0.43 mmol of trolox/g dry sample), and ORAC assays (2.84 mmol of trolox/g dry sample), as well as the highest content of TPC (140.4 mg) per gram dry sugar apple peel among the 10 cultivars. TPC showed a positive correlation compared with all antioxidant activity assays. In conclusion, ‘Fai Keaw’ could be utilized as an excellent phenolic compound source for functional food products.

title: Ion specificity in determining physico-chemical properties of drinking water

description: Abstract Drinking water plays a key role in regulating the daily salt intake, thus potentially affecting (either in positive or in negative direction) the incidence of diet-related pathologies, including nephrolithiasis. Being regarded as wholesome, bottled water is increasingly preferred to tap water. However, its physico-chemical characterization, as reported on the label, is usually limited to pH and conductivity measurements, along with ion content. Other parameters, which also are likely to influence the processes in which water is involved in the body, are usually neglected. In this work, the surface tension and density of tap water and two bottled mineral waters produced in Italy are investigated. These parameters are critically determined by the ion content. Density is connected to the total ion amount, while surface tension is differentially affected by the presence of specific ions: sulfate increases its value, while bicarbonate keeps it almost constant. These results furnish a reliable scientific basis for future investigation on the connection between the physico-chemical properties of drinking water and its effect on health. Particularly, since interfacial phenomena play a key role in kidney stone formation, our results suggest that dietary enrichment of selected ions due to water intake could affect nephrolithiasis.

title: Effect of Storage in Display Cases on the Sensory Quality of Chicken Breast Meat (M. Pectoralis)

description: ABSTRACT This paper describes a study on the determination of sensory quality of chicken breast muscles packaged with a PVC overwrap and under high-oxygen modified atmosphere (MAP: 75% O2 and 25% CO2), and stored in the display case (exposure to light and temperature fluctuations). For a more complete characterization of the raw material, the volume of drip loss in the package, and meat pH, L*, a*, and b* color components were measured. For comparison purposes, the quality of meat maintained under dark cold storage was also evaluated (control samples). In total, 64 PVC overwrap and 64 MAP packages were evaluated. Chicken breast muscles stored in the display case on PVC overwrap and in MAP packaging presented acceptable, despite but not the highest sensory quality until days 7 and 8 of storage, respectively. The meat under dark cold storage maintained high quality until the end of the experiment. When stored in the display case, packaging in MAP allowed extending chicken breast meat shelf life by at least 1 day in comparison with PVC overwrap packaging.

title: Eggshell Qualities as Indicative of Eggshell Strength for Layer Selection

description: ABSTRACT The study aimed at investigating which of four traits is the most representative of eggshell strength (destructive eggshell thickness measurement, eggshell weight, egg specific gravity, ultrasonic measurement of eggshell thickness) and could be used for selection purposes. To date, investigations focused mostly on pairwise (eggshell strength vs. another eggshell feature) analyses, resulting in two-, maybe three-trait, models when eggshell traits are considered. Since the covariance estimates are also model dependent, we collected five eggshell traits within one analysis, which better reflects what occurs in nature. The eggs were collected from 4571 Rhode Island White and 2426 Rhode Island Red hens. A multiple-trait animal model and the REML method were employed to compute variance components for calculation of heritabilities and genetic correlations between the traits. On average, the highest correlations were found between the destructive measurement and the other quality traits. It is concluded, however, that the ultrasonic eggshell thickness measurement, also with high genetic correlations with the other traits and leaving an egg intact for further handling, can suit best, as an indirect criterion, the selection for eggshell strength.
