中文摘要: 以玉米皮为原料,采用猴头菌固态发酵的方式生物改性玉米皮可溶性膳食纤维(soluble dietary fiber,SDF),研究猴头菌接种量、培养温度和培养时间对玉米皮可溶性膳食纤维含量的影响,通过单因素试验和响应面试验优化得到的最优工艺条件为接种量8%、培养温度25℃、培养时间7 d,该条件下实测玉米皮可溶性膳食纤维含量为(8.39±0.14)g/100 g。通过研究发酵前后玉米皮可溶性膳食纤维的吸附特性发现,发酵后玉米皮可溶性膳食纤维的亚硝酸盐吸附能力、胆固醇吸附能力和胆酸盐吸附能力均有所提高。
Abstract:The soluble dietary fiber(SDF)in corn husk was biologically modified by solid-state fermentation with Hericium erinaceus.The effects of H.erinaceus inoculation amount,fermentation temperature,and fermentation time on the content of SDF in corn husk were investigated.The conditions were optimized by single-factor tests and response surface methodology as fermentation at the inoculation amount of 8%and 25℃for 7 days.Under the optimum conditions,the measured SDF content was(8.39 ± 0.14)g/100 g.The adsorption capacity of the SDF after fermentation for nitrite,cholesterol,and cholate significantly increased compared with that before fermentation.
