The effect of oil-soluble rosemary extract, sodium erythorbate and a mixture of oil-soluble rosemary extract and sodium erythorbate and packaging method (vacuum packaging and modified atmosphere packaging) on the quality of cooked turkey meatballs stored at 4 °C was determined. The physicochemical, microbiological and sensory analyses were performed. Oil-soluble rosemary extract was found to be the most effectual antioxidant and vacuum more effective than modified atmosphere packaging in preventing oxidative changes. Sodium erythorbate slowed down hydrolytic process and more effective in modified atmosphere packaged samples. A slighter change in the colour of turkey meatballs was noted during modified atmosphere storage. Microbial counts of mesophilic bacteria during storage were never higher than the spoilage limit (10(7) cfu/g). All additives reduced microbial population and better effect was achieved by the combination of modified atmosphere packaging and additives. Sensory analysis results indicated the significant advantages in using rosemary individually or with sodium erythorbate in retarding warmed-over-flavour development in cooked poultry product.

The development of stable water-in-oil-in-water (W/O/W) emulsions for edible preservation coatings and films, utilizing their properties, deserves scientific attention. In this study, oregano essential oil and D‑sodium erythorbate were simultaneously loaded into W/O/W emulsions, and the homogenization conditions of the W/O/W emulsions were optimized. The structure and interactions of gum Arabic (GA) and whey protein isolate (WPI) as the outer phase were analyzed.

Article Synopsis
- * After 84 days of storage at 10°C, VP and MAP showed superior color stability and lower levels of total volatile basic nitrogen (TVBN) and lipid oxidation compared to AP.
- * The findings suggest that for maintaining quality, taste, and nutritional value, dry-cured ham should ideally be packaged using vacuum or modified atmosphere methods.
Modifying Cassava Starch via Extrusion with Phosphate, Erythorbate and Nitrite: Phosphorylation, Hydrolysis and Plasticization.

Extrusion processing of plasticized cassava starch, a prominent industrial crop, with chemical additives offers a thermo-mechanical approach to modify starch structures through physical and chemical interactions. This research investigates the interaction and morphology of thermoplastic cassava starch (TPS) blended with tetrasodium pyrophosphate (NaPO), sodium tripolyphosphate (NaPO), sodium hexametaphosphate (Na(PO)), sodium erythorbate (CHONa), and sodium nitrite (NaNO) via twin-screw extrusion. The effects of these additives on the chemical structure, thermal profile, water absorption, and solubility of the TPS were examined.

Browning significantly affects consumer perception, while texture hardening due to wound healing further reduces the commercial value of fresh-cut potatoes. This study evaluated the effects of 5 g L ascorbic acid (AA), sodium isoascorbate (SI), and calcium ascorbate (CA) on browning and wound healing during ambient storage. The results indicated that AA and SI were more effective than CA and the control in delaying browning and wound healing.
