This study examined the shelf life of cured sausage under different packaging conditions from vitamin E supplemented pigs. One group (n=6) of crossbred pigs received a normal fattening diet containing 20 ppm α-tocopherol for 39 days before slaughter. Another group was fed a diet containing 410 ppm α-tocopherol during the same period. After slaughter, cured sausages were produced, packaged under three different atmospheric conditions, ripened for 4 weeks and then stored for 8 weeks (9 °C; 200 lux). The α-tocopherol content was recorded in the fat, liver, muscles and the sausage. TBARS, L*, a*, b* values and antioxidative capacity were evaluated in the sausage during storage. The results showed a transfer of vitamin E into tissues and sausage but no detectable effect on TBARS and colour stability. However, antioxidative effects of vitamin E were seen by provocation. Probably the effect of vitamin E in the sausage was masked by nitrite in the curing salt. The oxygen content of the packs had an influence on TBARS and colour stability.

This study focuses on the development and application of tea polyphenol-loaded chitosan/polyaspartic acid nanoparticles (TP@CS/PASP-Nps) embedded within polyvinyl alcohol (PVA) nanofibers to extend the shelf life of fruit. The nanofibers were fabricated using electrospinning, which enhanced the stability and uniform dispersion of the nanoparticles. Experimental results demonstrated that the TP@CS/PASP nanoparticles exhibit significant pH and protease-responsive release of TP, with a cumulative release of 56.

The use of active packaging made from biodegradable polymers can contribute to the environment and to the food industry by increasing the shelf life of their products. This study aimed to produce chitosan-based films incorporated with the invertase enzyme (1, 2, 5, 9, and 10 %) as an alternative to avoid sucrose crystallization in the confectionery industry. The optimum activity of the invertase enzyme was observed at 55 °C and pH 5, thus, the films made with the film-forming solution adjusted to pH 5 and dried at 55 °C were compared with those without pH adjustment and dried at room temperature.

Multifunctional PLA films were fabricated through the solution casting method by incorporating cardanol oil (CA) and amine-functionalized graphene (AFG). The effect of the CA, and AFG on the structural, mechanical, thermal, thermo-mechanical and antioxidant properties of PLA films were investigated. FTIR analysis of PLA-CA films showed distinct peak positions at 1590 cm corresponding to the aromatic CC bonds of CA, showing that CA is compatible with the PLA.

In the background of antioxidation properties of selenium (Se) in plants, the role of nano‑selenium (Se-NPs) was justified in the modulation of Capsicum fruit ripening. In our study, exogenous application of 8 mg L Se-NPs on fruits through 7 days (D) of postharvest storage regulated decay rate, water loss and fruit coat firmness. Se-NPs recovered fruit coat damages with reduction of ion leakage, lipid oxidation, and accumulation of polyamines.

The widespread reliance on single-use plastics (SUPs) has fostered a global throwaway culture, especially in the food packaging industry, where convenience and low cost have driven their adoption, posing serious environmental threats, particularly to marine ecosystems and biodiversity. Edible and ecofriendly packaging made from millet, specifically sorghum ( () Moench), is a promising solution to mitigate SUP consumption and promote sustainability. This study explores the development of edible sorghum bowls, enhanced through roasting and incorporating 3 g of hibiscus and rose flower powders.
