In this study, 10% of chicken protein isolate (CPI) and quercetin (1 mg/mL) were used to develop an edible coating to improve the oxidative stability of deep-fat-fried chicken drumsticks during refrigerated storage (4 °C) for 10 days. Chicken samples with edible coating formulated with only 10% CPI served as the control. Although the thiobarbituric acid reactive substances (TBARS) values of the treated samples were lower than the control samples, no significant differences were observed. Quercetin-treated samples were generally harder than control samples. The pH was reduced by quercetin incorporation (p < 0.05). L* and b* values increased, while there was no significant variation in a* values during storage (p > 0.05).

<p>The aim of this study was to evaluate the effects of turmeric powder and ascorbic acid on lipid oxidation and antioxidant capacity in cooked rabbit burgers. The burgers were derived from 3 different formulations (C, control, with no additives; Tu with 3.5% of turmeric powder and AA with 0.1% of ascorbic acid) and were stored at 4°C for 0 and 7 d and cooked. The lipid oxidation (thiobarbituric acid reactive substances [TBARS]) and antioxidant capacity (2,2-azinobis-[3 ethylbenzothiazoline-6-sulfonic acid] {ABTS}, 1,1-diphenyl-2-pircydrazyl [DPPH] and ferric reducing ability [FRAP]) were evaluated. A significant interaction between storage time and formulation (P&lt;0.001) was observed for DPPH, FRAP and TBARS in cooked burgers. At day 0 and day 7, the DPPH value was higher in Tu and AA compared to C burgers. At day 0, C showed a lower level of FRAP than the Tu and AA burgers. At day 7, the FRAP values tended to decrease but remained significantly higher in Tu and AA compared to C burgers. Lipid oxidation at day 0 in Tu and AA showed lower TBARS values compared to C burgers. The addition of 3.5% turmeric powder in rabbit burgers exerts an antioxidant effect during storage and it seems more effective in controlling lipid oxidation than ascorbic acid after cooking.</p>

Antioxidant And Antimicrobial Activities

Pork is perishable due to oxidation and microbial spoilage. Edible coating based on biopolymers and phenolic compounds is an effective way to preserve the quality of pork. In this study, ferulic acid-grafted-CS (ferulic acid-g-CS) with strong antioxidant and antimicrobial activities was synthesized through a carbodiimide-mediated coupling reaction. The obtained ferulic acid-g-CS was used as an edible coating material for fresh pork. The effect of ferulic acid-g-CS coating on the quality of pork during storage was investigated at 4 °C for 8 days. As compared to the uncoated pork, pork coated with CS and ferulic acid-g-CS showed lower total viable counts, total volatile basic nitrogen values, pH values, thiobarbituric acid reactive substances, and drip losses. Besides, pork coated with CS and ferulic acid-g-CS presented more compact microstructures than the uncoated pork at the eighth day. Sensory evaluation assay showed pork coated with CS and ferulic acid-g-CS had better color, odor, and over acceptance in comparison with the uncoated pork. Ferulic acid-g-CS coating, due to its relatively higher antioxidant and antimicrobial activities compared to CS coating, had a better performance in refrigerated pork preservation. Ferulic acid-g-CS coating effectively extended the shelf life of refrigerated pork to 7 days. This study revealed ferulic acid-g-CS coating was a promising technology for refrigerated pork preservation.

Fresh ground beef patties with (1) no antioxidant (control), (2) 0.02% butylated hydroxyanisole/butylated hydroxytoluene (BHA/BHT), (3) 3% dried plum puree, or (4) 0.25% rosemary extract were aerobically packaged, irradiated at target doses of 0, 1.5, or 2.0 kGy (1.7 and 2.3 kGy actual doses), and stored at C. The samples were evaluated for lipid oxidation on 0, 3, 7, 14, 21, and 28 days of storage after irradiation. When compared to the control, all antioxidant treatments were effective in retarding () irradiation-induced lipid oxidation during storage as determined by 2-thiobarbituric acid reactive substances (TBARs) values. Rosemary extracts had the same antioxidant effect () as BHA/BHT in irradiated and nonirradiated beef patties, followed by the dried plum puree treatment. Irradiation increased TBARs values, but no differences were noted in oxidation between irradiation dose levels.

Uniform design was adopted, and two factors, i.e., frozen at different time postmortem with six levels, thawing at different thawing rate with three levels, were considered. Thiobarbituric acid reactive substances (TBARS), pH and sensory evaluation were measured to study the different effects of the two factors considered. The results showed: All the two factors considered had significant effects on pH and TBARS, and the effects of the two factors on them were nonlinear. But they had no significant effects on sensory evaluation. TBARS values representing the storage quality of raw sausages was only affected by thawing rate in the test, and had the maximum at the thawing rate of 3cm/h thawed in 19.5°C still air. So when using frozen raw meat for sausage production, selecting an appropriate thawing condition is very necessary.

The objective of this research was to determine physicochemical changes and microbiological quality of the different packaged meatball samples. Meatball samples in polystyrene tray were closed with polyethylene film (PS packs), vacuumed and modified atmosphere packaged, (MAP) (65% N2, 35% CO2), and held under refrigerated display (4 °C) for 8, 16 and 16 days for PS packs, vacuum and MAP, respectively. Microbial load, free fatty acids and thiobarbituric acid values of the samples tended to increase with storage time. Bacteria counts of the raw meatball samples increased 2 log cycles at the end of storage compared with initial values. Meatball samples can be stored without any microbiological problem for 7 days at 4 °C. Results from this study suggested that shelf-life assigned to modified-MAP and vacuum-packed meatballs may be appropriate. Meatball samples underwent physical deformation when they were packed before vacuum process. With these negative factors considered, MAP is superior to other two packs methods.

Quality characterizes of surimi of silver carp at two different conditions of superchilling and cooling freshness preservation. The pH value, thiobarbituric acid-reactive substances (TBARS value), protein soubility and ATPase activity were studied. The result showed that pH value and TBARS value increased with the increasing of the storage time (P < 0.05), protein soubility and both ATPase activity decreased with the increasing of the storage time (P < 0.05). In general, superchilling is a good way to preserve freshness of fresh products and the raw material before processing, and also could have great effect on improving the quality characterizes of surimi and prolong its shelf life.

Minimizing microbial growth and maintaining overall quality are priorities for intervention strategies that extend the shelf life of fresh, aquatic foods. Four treatments included a control (fresh fillets), water, 50 ppm of acidified sodium chlorite (ASC), and 1,000 ppm of ASC. Fillets were stored at 1 to 2°C for 0, 8, and 15 days. A significant (P &lt; 0.05) interaction between treatment and storage time was observed for psychrotrophic counts. The increase in psychrotrophic counts with storage time was less for fillets treated with ASC, regardless of ASC concentration. Aerobic plate counts were not affected (P &gt; 0.05) by intervention; however, a significant increase in counts was observed during storage (P &lt; 0.05). Fillet pH, moisture, fat, thiobarbituric acid–reactive substances, fatty acid composition, color, cook yield, and shear force were not affected (P &gt; 0.05) by intervention. Thiobarbituric acid–reactive substances decreased (P &lt; 0.05) during storage. Percentages of individual fatty acids were constant, with the exception of C15 and C20:2; they decreased with storage to 15 days. Percent fat, L* (lightness) and b* (yellowness) values, and cook yield increased (P &lt; 0.05) during storage. Fillet pH, moisture, a* (redness) value, and shear force did not change (P &gt; 0.05) with storage to 15 days. Based on these data, 50 ppm of ASC performed equally as well as 1,000 ppm of ASC. The value of ASC is as a decontaminant; however, fillets in this study had low psychrotrophic counts pretreatment (2.3 log CFU/cm2) and posttreatment (2.03 log CFU/cm2), which did not demonstrate ASC's effectiveness as a decontaminant.

Positive Effect

The work deals with a study of the effect of natural antioxidants – rosemary extracts in powder and liquid forms, respectively, on the quality of a heat-untreated meat product. Effect of added antioxidants was estimated in samples taken from the meat product mixture, from a ready-made product immediately after smoking, after 28 days – at the expedition of the meat product and then after further 28 days of storing at different ambient temperatures. Marked positive effect of the applied antioxidants was noted especially during storing when the peroxide and thiobarbituric acid reactive substances (TBARS) values of fats increased more slowly compared to meat products manufactured without added antioxidants. Subsequent sensory analysis shows also preferences for the antioxidant treated meat products.
