The Sicilian sumac ( L.) is considered an excellent source of natural polyphenols whose antioxidant activity is able to affect specific technological functions. The effect of the addition on the quality of beef burgers before and after cooking was evaluated, by pH, colour, protein (-SH) and lipid oxidation, total phenol content and antioxidant activity (ABTS assay). The sumac in burgers (THs) resulted in a significant increase in all dry matter components (P < 0.05), while water content and pH value decreased. Furthermore, THs, compared with control burgers (CHs), were characterised by lower L* and peroxidation values and higher a* and b* values ( < 0.05). The added in the burgers positively influenced the total phenolic content and antioxidant activity values. Cooking reduced content of phenols, -SH groups and antioxidant activity. However, in THs the reduction of -SH, phenols and antioxidant activity was more limited than in CHs ( < 0.05). Sensory analysis showed a higher appreciation for THs by consumers for all the considered attributes. The ground meat incorporated with sumac could be a valid strategy to improve its quality and sensorial evaluation.

In this study, the nano chitosan particles were produced by ionotropic gelation between sodium tripolyphosphate and chitosan. The effect of nano chitosan with or without sodium lactate coating was evaluated on physicochemical (pH, thiobarbituric acid, total volatile basic nitrogen, and peroxide), microbial (total mesophilic and psychrotrophic viable counts, lactic acid bacteria, yeasts, and molds), and sensorial properties of beef burgers within 24 days of storage at 4°C. The solutions of 1% nano chitosan (T), 2% nano chitosan (T), 2.

The objective of this study was to characterize the nutritional profile of plant-based meat alternatives (PBMA) and ground beef (GB). Beyond Beef (BEY); Impossible Burger (IMP), a third available product of plant-based protein, including SWEET EARTH, Incogmeato, Open Nature, and Good & Gather (GEN); and two lean levels of GB (regular [80%-85% lean, regular ground beef] and Lean [>93% lean, lean ground beef, LGB]) were purchased from retail stores across the United States. Proximate composition, mineral content, fatty acid profile, amino acid profile, and B-vitamin content were measured in raw products.

This study was conducted to develop biodegradable films using a combination of carboxymethyl cellulose (CMC), polyvinyl alcohol (PVA) and purified leaves extract of Astragalus tribuloides (ATE). Various traits of the films, including their morphology description, thermal behavior, tensile/elongation properties and physical characteristics were examined. The scanning electron microscope (SEM) photographs showed smooth surface with small amounts of ATE, but rougher with higher concentrations of 1.

This study aimed to evaluate the effect of fat level and meat cut type on burger meat through color, texture, image, and sensory analyses, and to explore the ability of the imaging technique as a complementary tool for consumer quality perception. For this purpose, burger meat samples were prepared by combining pork and beef meat (50/50%) with other nonmeat ingredients. The differences between samples were fat level: around 15 g fat/100 g (code HF) or 10.

Article Synopsis
- * Two fat replacers, lemon albedo and carob seed gum, were analyzed for their effects on the burgers, along with plant extracts from nettle leaves and medlar seeds that were tested for antimicrobial and antioxidant properties.
- * Results showed that while the fat replacers improved nutrition and taste, they did not guarantee safety, indicating that combining them with natural antimicrobial extracts, like medlar seeds, is crucial for producing safe low-fat burgers.
