ABSTRACT
The use of Pleurotus ostreatus to reduce calories and increase bioactivity in processed meat products is an increasingly common practice. In this study, a novel sausage containing P. ostreatus was developed based parameters like protein, antioxidants, total phenolic content, cohesiveness, energy, fat, ΔE, hardness, and gumminess values using a D-optimal mixture design. The results showed that over 20% of P. ostreatus could be used in sausage production. Moreover, it was concluded that the optimized sausages contain less fat (33.05%) and meat (18.6%) and therefore have a lower calorie value (19.03%). In addition, P. ostreatus added to the sausage formulation decreased the use of animal raw materials, increased the bioactive properties of the sausages, and did not cause a significant change in the amino acid profile.

The objective of this study was to develop novel micro-nanofibers for food packaging using grapevine extract (GLP) and gelatine using electroblowing technique. The identified components of GLP were dominated by the flavone group phenolics, as analyzed by LC-MS/MS. SBS was used to fabricate gelatine micro-nanofiber mats loaded with three different concentrations of GLP, which were subsequently cross-linked. The micro-nanofibers were characterized by their morphology, chemistry, thermal properties, and bioactivity. The in-vitro antioxidant and antimicrobial effects of the nanofiber mats were determined using various methods, which showed an increase in effectiveness with increasing GLP concentration. The in-situ assessment, where the nanofibers were applied to cheese, also showed a consistent improvement in shelf life with the use of GLP-loaded gelatin electroblown fibers.
