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 20% skim milk color charm wella 050 exhibited approximately one log reduction.In an 8-week preservation test, the log (CFU/g) of B.longum MYL16 without protectant decreased from 9.

21 to 0, while that of B.longum MYL16 treated with 20% polysaccharide with 20% skim milk just decreased from 9.13 to 8.82.

In terms of sensitivity of B.longum MYL16 to digestive process, the log (CFU/g) of B.longum MYL16 without protectant decreased from 9.20 to 2.

91, while that of B.longum MYL16 treated wuh721414ale6l1 with 20% polysaccharide with 20% skim milk merely decreased from 9.26 to 7.83.
