Application of hull, bur and leaf chestnut extracts on the shelf-life of beef patties stored under MAP: Evaluation of their impact on physicochemical properties, lipid oxidation, antioxidant, and antimicrobial potential.
The impact of chestnut extracts (Castanea sativa) from leaf, bur and hull at different concentrations on the shelf-life of beef patties during 18 days of refrigerated storage at (2 ± 1 °C) was studied and compared to control and synthetic antioxidant (BHT) samples. Total phenolics and in vitro antioxidant capacity of extracts were evaluated by using DPPH, FRAP, reducing power and oil accelerated oxidation test (peroxide value, conjugated dienes, p-anisidine and fatty acid profile). The microbial spoilage, colour parameters, lipid oxidation and sensorial properties were used to assess antioxidant activity in beef patties. The highest total phenolic content was found in bur extracts (43.68 ± …
Green technologies for food processing: Principal considerations
Abstract The environmental impact of the food industry is of increasing concern for our society. Reductions in the amounts of harmful substances produced and in energy consumption, and increases in by-product recycling, are all requirements that the industry must now meet. However, “green technology” concepts are currently driving the development of new techniques in this field. Emerging green technologies are capable of superseding conventional thermal treatment, which negatively affects the physical, nutritional, and bioactive properties of food, and are also more environmentally friendly. Novel green techniques include ionizing and ultraviolet radiation, ohmic heating, high-power ultraso…
In vitro bioactive properties of phlorotannins recovered from hydrothermal treatment of Sargassum muticum
Abstract The present work addresses the potential of different adsorbents for the recovery of the phlorotannin fraction present in the liquid phase from the autohydrolysis of Sargassum muticum. Operating with the extract generated during autohydrolysis of alginate exhausted algae, the kinetics followed pseudo-second order and the equilibrium corresponded to Freundlich model. In batch configuration, up to 70% phlorotannins were adsorbed and up to 30% were desorbed with ethanolic solutions. Comparable performance was observed with the autohydrolysis extracts from the whole algae. The phloroglucinol content, the reducing and ABTS antiradical capacities of the desorbed product increased by 2–4 …
