Abelmoschus esculentus (L.) Moench polysaccharide enhances the resistance of Bifidobacterium longum MYL16 to freeze-drying and artificially digestive processes

The protective effect of Abelmoschus esculentus (L.) Moench polysaccharide for Bifidobacterium longum MYL16 from freeze-drying and digestive processes was investigated.Our results indicated after freeze-drying, the log (CFU/g) of B.longum MYL16 without protectant decreased from 10.52 to 4.98, while supplementation of 20% polysaccharide with GRUNDIG
