| 1 | Comparative analysis of the antioxidant capacity and lipid and protein oxidation of soy and oats beverages显示文摘Soy(Glycine max)and oats(Avena sativa)are plant sources used in milk-alternative beverages.However,protein and lipid constituents of these food matrices can undergo alterations during the storage.In this work,a commercial formulation of soy and oat-based beverages were comparatively evaluated.During the 12 months of shelf life and two following months,their phenolic content,antioxidant capacity,lipid peroxidation,protein carbonyl formation and protein breakdown were assessed.Total phenolic content and antioxidant capacity of soy and oat-based beverages were maintained during the entire period of 14 months.Both beverages did not show any increase in spontaneous lipid peroxidation beyond the basal level,however,due to the different content of unsaturated fats,when lipid peroxidation was stimulated,soy exhibited a major peroxidizability with respect to oat beverage.Oxidative alteration of proteins,estimated as carbonyl group formation,presented no increase with respect to the basal levels both in soy and oat beverages for all 14 months.Finally,soy proteins showed a gradual increase of proteolytic activity up until half of the shelf life,while oat did not show significant changes in protein fragmentation.In conclusion,both soy and oat beverages resulted oxidatively stable throughout their storage.We suggest that phytochemicals might guarantee the oxidative stability of the product,possibly in combination with antioxidant bioactive peptides,which already have well-known benefits on human health. | Laura Moretto Federica Tonolo Alessandra Folda Valeria Scalcon Alberto Bindoli Marco Bellamio Emiliano Felle Maria Pia Rigobello | 2021 | Food Production, Processing and Nutrition2021，3，1： | 0 |
