title: Development of diet cereal bar sweetened with stevia leaves pre-treated with ethanol

description: Abstract The objective of this work was to perform the ethanolic pretreatment of stevia leaves from the plant Stevia UEM-13 line and to characterize its physical-chemical properties aiming its use as a sweetener in the development of a diet cereal bar. The same formulation of the cereal bar with stevia leaves without pretreatment was elaborated for comparative purposes. The following ingredients were used in the preparation of the produtc: fine oat flakes, no sugar granola, cranberry, dehydrated apricots, water, gum acacia and stevia leaf pretreated (F1) and without treatment (F2). According to the results, the diet cereal bars presented significant amounts of crude fiber, protein and antioxidant activity. The product was microbiologically safe for human consumption, reporting lower microbiological valuesthan those foreseen by official regulation. The overall sensory evaluation indicates that the two formulations did not present statistically significant differences regarding the analyzed attributes, being the averages between “liked very much” and “moderately liked”. However, considering the group of cereal bars consumers, the formulation sweetened with pretreated leafs (F1) was found more than twice the acceptance regarding to the formulation sweetened with the leaf in natura (F2). These results demonstrate a viable option of a diet food product naturally sweetened.

title: Physicochemical properties, antioxidant activities and sensory characteristics of commercial gape vinegars during long-term storage

description: Abstract This study was designed to investigate changes in quality characteristics during long-term storage of five commercial grape vinegars (V1~V5). To determine long-term quality characteristics of vinegars, proximate (soluble solid, pH, total acidity, color, and antioxidant activity) and sensory descriptive analysis, were performed. Initial soluble solids were high in V4 and V5 (contained higher liquid fructose or grape concentrate), but after 12 mo of storage, soluble solids decreased significantly in V4 and V5 (non-sterile products). Initial total acidity was close to the amount of additional juice, while V4 and V5 had increased total acidity after 12-mo storage. Browning was dominant in V4 and V5 regardless of storage periods. Initial DPPH radical scavenging activity was high for all samples, while it tended to decrease after 6-mo storage. In sensory descriptive analysis, browning and turbidity was markedly elevated during 12-mo storage in general. Aromatic factors were significantly attenuated in all test samples during storage. Interestingly, V4 and V5 were considered as having lower sourness and bitterness since sweetness was stronger in these than in other samples due to the addition of liquid fructose. The results suggest that for optimal quality, commercial grape vinegars are best consumed within 6 mo of storage after opening.

title: Proximate composition and sensory evaluation of salted pearl mullet (Chalcalburnus tarichi Pallas, 1811) produced using different methods

description: Abstract The aim of this study was to determine the proximate composition and sensory scores of the salted pearl mullet (Chalcalburnus tarichi Pallas, 1811) produced using different methods. It was determined that the OS11 group had the highest amounts of dry matter and protein (82.77 ± 0.52% and 44.52 ± 0.28%) (p &lt; 0.05). The OS11 group had the highest value of energy (404.59 ± 1.33 kcal/100g) (p &lt; 0.05). The highest taste score (6.88 ± 0.83) and the highest overall acceptance score (7.25 ± 0.73) in raw samples were obtained by the NS31 group and the NS32 group (p &lt; 0.05), respectively. It was observed that the salted pearl mullet (C. tarichi Pallas, 1811) produced by using different methods had a high nutritional value. While the samples produced in the previous season (last year) were liked less according to the results of the raw sensory analysis, the samples of the new season, except for the samples produced by using dry salting method in bottom perforated plastic can be liked less according to the result of the cooked sensory analysis.

title: Monitoring and health risk assessment of selected trace metals in wheat rice and soil samples

description: Abstract Wheat and rice constitute important cereal crops and any contamination may pose potential adverse impacts on human health. The study was conducted to determine eight trace metals, i.e. cadmium (Cd), copper (Cu), cobalt (Co), chromium (Cr), zinc (Zn), lead (Pb), nickel(Ni), manganese (Mn), in wheat, rice and soil samples collected from different cities of Punjab. Results showed general trend of trace element accumulation in samples as Cd &gt;Cu&gt;Zn&gt;Co&gt;Mn. All wheat and nine rice samples exceeded permissible limit of Cd. Copper in eight wheat and rice samples and Zn levels in three wheat and one rice samples were in excess. While only one soil sample of Multan exceeded the WHO 2007 and EU 200 0 maximum allowable limit for Cu. Manganese and Co concentration were within allowable limit, while Ni, Cr and Pb were not detected in any sample. Health Risk Index was higher than 1 for Cu, Cd, Co and Mn thereby showing potential health risks to consumers.

title: Nutritional, physicochemical and anatomical evaluation of creole corn varieties from the region of the Costa Chica of Guerrero

description: Abstract Corn (Zea mays) is the most consumed cereal in México, so it is necessary to know the nutritional and anatomical quality of the grains, which have been the main conservation and consumption criteria of the prehispanic peoples. This practice has allowed to preserve varieties of Creole corn, however, due to the lack of knowledge of these characteristics the cultivation of these maize has been reduced, presenting a high risk of disappearing. The objective was to determine the physical, nutritive and functional quality of four varieties of creole corn: Purple-Olotillo, Dos-Puntas, Toro and Olotillo. Toro presented the highest values of width and thickness (10.79 and 7.71 mm). The Toro showed better values of Endosperm and Pericarp (84.25% and 4.01%), Dos-Puntas and Olotillo showed higher values of Germ (10.75%) and Pericarp (6.2%), respectively. The Toro had a higher content of Carbohydrates and Proteins (74.47 and 10.61%). In WSI, the best value was obtained by Dos-Puntas (11.91%) and WAI the Olotillo (245.56 g H2O/g sample). It is concluded that the Toro has better nutritional content and larger and weight grains, while the Olotillo presented the highest values of WAI, it can confer better technological properties for food processing.

title: The effect of the commercial fish gelatin protein hydrolysate on rainbow trout (Oncorhynchus mykiss) fillet quality

description: Abstract Willing to increase the shelf life of the food matrix, studies regarding new preservations methods are developed to preserve fish deterioration. The application of natural additives as preservatives is increasingly common, with a current emphasis on the growing use of protein hydrolysates, in substitution to artificial ones. These compounds have been the subject of recent studies, focusing on determining their functional properties and the best form of applying peptide chains. The present study aimed to evaluate the effects of the protein hydrolysate obtained by the enzymatic hydrolysis of commercial fish gelatin added to rainbow trout fillets (Oncorhynchus mykiss) packed under vacuum and maintained under refrigeration. The fillets were distributed into three sample groups (controls and hydrolysate addition at 1:10 and 1:1 ratios). Microbiological and physico-chemical assessments were carried out. The results were compared and correlations observed regarding fish preservation assessments. A relationship between pH, redox potential and N-TVB was verified when compared to microbial development, especially with regard to psychrotrophic aerobic heterotrophic bacteria count. It was concluded that the application of protein hydrolysate as an additive is promising and can be effective in the control of food quality and maintenance of freshness for a longer period.

title: Effect of the application of ultrasound on sarcoplasmic proteins from giant squid (Dosidicus gigas) mantle

description: Abstract This research studies the application of ultrasound (US) on sarcoplasmic proteins from giant squid (Dosidicus gigas) mantle and its effect on its functional properties. US was applied during 30, 60 and 90 s. A decrease was observed in the emulsifying activity index (EAI), an increase in the emulsifying stability index (ESI), an increase in the foaming capacity (FC) and a decrease in the foaming stability (FS). In addition, the application of US increased the surface hydrophobicity (So) and decreased the viscosity with the increase in temperature. Functional properties of sarcoplasmic giant squid mantle proteins increase with the application of ultrasound.

title: Preparation of antioxidant peptides from hairtail surimi using hydrolysis and evaluation of its antioxidant stability

description: Abstract In this study, antioxidant peptides were prepared from hairtail surimi by hydrolysis. Response surface methodology coupled with a Box-Behnken design was applied to optimize hydrolysis conditions. The optimum conditions were determined as: 12.1 h incubation time, 44.74 °C incubation temperature and enzyme concentration 1858.85 U/g. The amino acid compositions analysis showed most abundant amino acid in hairtail surimi antioxidant peptides (HAP) was Glutamic acid followed by Aspartic acid and Lysine. In addition, the fraction of HAP with a molecular weight less than 3 kDa showed the strongest antioxidant activity among the 4 fractions obtained by ultrafiltration. Furthermore, HAP showed good stability in mild acidic, alkaline, or salt solutions, in in vitro digestive juice, and upon heating. In conclusion, hairtail surimi might be a good source to produce antioxidant peptides, which can be used as a natural antioxidant in food industry.
