中文摘要: 该文以燕麦碎米及皮粉为主要原料,采用模糊评价和响应面法结合,考察以自制燕麦麸曲进行糖化液化对燕麦营养醋的影响。确定最佳工艺条件为麸曲添加量0.4%、糖化温度62℃、糖化时间6.4 h、糖化pH5.2,该条件下所得燕麦营养醋的感官评分为92.71±1.15,总酸含量为5.12 g/100 mL,总黄酮含量为3.64 mg/mL,总酚含量为57.2 mg/100 mL,可溶性固形物含量为4.27 g/100 mL,所得燕麦营养醋色泽清亮,呈棕红色,具有燕麦营养醋所特有的香气和滋味,无沉淀。
Abstract:Broken oats and hulls were used as the main raw materials to produce oat vinegar.The effects of saccharification conditions on the self-made oat vinegar were investigated by fuzzy evaluation and response surface methodology.The saccharification conditions were optimized as follows:bran koji addition amount of 0.4%,62℃,6.4 h and pH5.2.The oat vinegar produced under these conditions had the sensory score of 92.71±1.15,the total acid content of 5.12 g/100 mL,the total flavonoid content of 3.64 mg/mL,the total phenol content of 57.2 mg/100 mL,and the soluble solid content of 4.27 g/100 mL.The obtained oat vinegar has a clear brownish-red color,unique aroma and taste,and no precipitation.
