农村薯渣资源十分丰富,未经发酵处理,其营养价值低,经酵母菌发酵后营养显著提高。薯渣发酵方法规模小,操作简便,投资少,见效快,很适合农产加工生产。一、种曲制备:将1:1的麦麸和水混匀,分装于培养皿中(每公斤麦麸可装直径9厘米培养皿200个)高压灭菌(每平方厘米1.3公斤)后,当料温降至50℃以下时接种(接试管中培养好的酵母菌),于32℃条件下培养3—4天。
Rural potato residue is very rich in resources, without fermentation, its nutritional value is low, the yeast nutrition after fermentation significantly increased. Small size of potato residue fermentation, easy to operate, less investment, quick, it is suitable for agricultural processing and production. First, the kind of music preparation: The 1: 1 wheat bran and water mixing, sub-packed in petri dishes (per kilogram of wheat bran can be loaded with 9 cm diameter petri dishes 200) autoclaved (1.3 kg per square centimeter) , When the feed temperature dropped below 50 ℃ when inoculated (then cultured in the test tube yeast), cultured at 32 ℃ for 3-4 days.
