摘要:

本研究以豆粕和米糠为固态培养基,固体发酵生产冬虫夏草多糖。通过对培养基组成配比、接种量、温度、培养基相对湿度、空气相对湿度和培养时间的研究,初步确定了在豆粕:米糠为1:2(W/W)固体培养基发酵生产冬虫夏草多糖的最佳条件为:接种量20%、温度26℃、培养基含水量为60%、空气相对湿度为60%和培养时间7d。经傅立叶红外光谱分析,本研究生产的冬虫夏草多糖为β-葡聚糖。

关键词: 豆粕, 米糠, 冬虫夏草, 葡聚糖, 固体发酵

Abstract:

In this study, Cordyceps sinensis polysaccharide was prepared by solid fermentation with soybean meal and rice bran (1:2, W/W) as raw materials of medium. Through single-factor test, the optimum inoculation amount, fermentation temperature, water content of medium, air relative humidity and fermentation time are confirmed to be 20%, 26℃, 60%, 60% and 7 days, respectively. Fourier transform infrared spectroscopy analysis indicated that the Cordyceps sinensis polysaccharide is β-glucan.

Key words: soybean meal, rice bran, Cordyceps sinensis, glucan, solid fermentation
