Fermented oat-based foods offer attractive prospects within the market of non-dairy functional products, since they are suitable substrates for the delivery of probiotic microorganisms, and are significant sources of dietary fiber, both insoluble and soluble such as β-glucan, good quality fat and other phytochemicals important for human health In the present work, whole oat flour was fermented with probiotic Lactobacillus plantarum strains to produce new functional foods with improved nutritional and technological features. Viability of the probiotic and the main technological, physico-chemical, nutritional and sensorial parameters were monitored at 7, 14 and 21 days of cold storage. The microbial survival was higher than 5x10 8 cfu g-1 at the end of the shelf life. After the fermentation step, viscosity was higher in products inoculated with the exopolysaccharide-producing L. plantarum strain Lp90. However, a subsequent viscosity reduction was detected in all the samples throughout the storage period, consistent with the observed concentration decrease of the oat β-glucan. Vitamin B2 content was about twofold higher in products fermented by the riboflavin-overproducing LpB2, and in these samples the riboflavin concentration further increased during cold storage. Highlights Fermented oat-based foods are suitable substrates for delivery probiotic LAB. Riboflavin-overproducing LpB2 increased the vitamin B2 content of oat-based products. EPS-producing Lp90 seems to improve some rheological features.
The results showed that table grape sensory quality could be increased by delaying harvest up to a certain time of the season, while excessive delay could reduce final grape quality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
