Study on the effect of precipitation of milk protein by trichloroacetic acid analyzing with biuret spectrophotometry method
摘要
Abstract
The effect of precipitation of milk protein by heating and different concentration of trichloroacetic acid (TCA) was analyzed by biuret spectrophotometry method,and it was influenced by pH that the effect precipitation of milk protein by TCA.Results showed that it was influenced by concentration of TCA that the effect of precipitation milk protein by TCA were analyzed by biuret spectrophotometry method, when using standard biuret spectrophotometry, and the concentration of TCA ≤ 15％.When TCA ＞ 15 ％, it must adjust the pH above 11.When pH≥11 ,the delicacy change of pH didn' t affect OD.There was no obvious difference between heating and not heating on the precipitation effect of milk protein by TCA.关键词
