摘要：

Araboxylan (AX) and/3-glucan (BG) were extracted and purified from highland barley bran, respectively. It was found that both AX and BG could promote the proliferation of Lactobacillus (L.) plantarum and producing short-chain fatty acids, suggesting potential intestinal probiotic effects of AX and BG. Based on this, Lactobacillus plantarum GIM1. 191 was co-microcapsuled with AX (M-AX) and BG (M-BG), respectively, and their effects on the encapsulation efficiencies, gastrointestinal tolerance and storage were evaluated. The results showed the encapsulation efficiencies of M-AX and M-BG were increased by 1.4 times, and 1.6 times, respectively, compared with the control group (M-S). After simulated gastrointestinal digestion, no viable probiotics was detected in M-S, however, the viable counts of M-AX and M-BG groups were 5.70 and 6.3 lg (CFU/g), respectively. In addition, AX and BG extended the storage time [viable probiotics counts >6 lg (CFU/g)] from 21 days to 35 days under 4 t, and significantly increased the viable probiotics counts at day 14 under 26 C. These results will provide theoretical basis and technical support for the high value utilization of highland barley bran. © 2023 Chinese Institute of Food Science and Technology.
