摘要
研究了食用盐酸水解米渣的工艺条件,通过单因素实验及正交实验,得到酸水解的最佳作用条件是水解时间11h、料液比1∶7、盐酸浓度6mol/L,各因素的影响作用大小是水解时间>料液比>酸浓度。糖用活性炭的最佳脱色条件是活性炭用量8%、室温、脱色时间2min,在此条件下脱色率可以达到99.5%。
The technics of acid hydrolysis of rice residue protein was studied. Premium working conditions for the hydrolysis were determined by means of orthogonal experiments. The best conditions of hydrolysis were as follows： the time is 11h, the ratio of raw material mass to acid volume is 1：7, and the concentration of hydrochloric acid is 6mol/L. An ordinal rank of influence is time, the ratio of raw material mass to acid volume and the concentration of hydrochloric acid. The best conditions for the effect of active carbon are as follows： active carbon dosage is 8%, under room temperature and the time is 2min. in such conditions the ratio of discolouration is 99.5%.
