Abstract
The consumption of probiotic foods is rather limited for many sectors of the population (vegans, lactose intolerant and celiacs). Therefore, it is necessary to offer functional alternatives for these sectors. Different red quinoa drinks were fermented with L. plantarum (QLPBB) and B. longum (QBLBB) at different times. Results showed that microbial concentration reached high levels (6–8 Log CFU/mL) after 6 h and probiotic viability was very high (6 Log CFU/mL) after gastrointestinal digestion (GD). However, QBLBB reached the best probiotic concentration at 24 h. From 6 h of fermentation, probiotic resistance to some antibiotics, especially B. longum, could have a great potential to restore the intestinal microbiota during and after treatment with certain antibiotics. QLPBB showed the highest levels of total polyphenols and antioxidant capacity (AOC) after GD. Therefore, these red quinoa drinks have potential as functional probiotic beverages for vegans, celiacs and allergic to milk protein and lactose-intolerant people. [ABSTRACT FROM AUTHOR]
