【摘要】 采用正交试验法,用粉末活性炭对大豆多肽进行脱色处理,比较各因素(活性炭用量、pH、温度和时间)对脱色结果的影响。结果表明:2%的活性炭用量、pH3、脱色温度50℃、吸附时间3h,大豆多肽脱色效果明显,肽氮的损失率为18.88%。更多还原

【Abstract】 Activated carbon was chosen as decolouring agent of soybean peptide, the effect of the activated carbon concentration, pH, temperature and period of absorption on decolouring was studied. The result showed that high degree of discolouration could be obtained under the following conditions: activated carbon concentration 2%, solution pH value 3, temperature 50℃, absorption time 3h, and the loss rate of soybean peptide was 18.88%.更多还原
