| 摘 要： | 根据Tilsit干酪加工方法制作生干酪样品,在90 d成熟内测定其总氮、水溶性氮(WSN)、三氯乙酸水溶性氮(TCA-SN)、磷钨酸水溶性氮(PTA-SN)等含量,研究成熟过程中蛋白质水解程度。上述指标,除磷钨酸水溶性氮,其余均与干酪成熟期呈现一定的线性相关性(p<0.05),该多元线性回归模型可以用于鉴定和预测Tilsit型干酪的成熟期。

| Abstract: | The manufacture method of Tilsit type cheese was applied to prepare young cheese samples.The percentage of total nitrogen,water soluble nitrogen,trichloroacetic acid in nitrogen soluble,phosphotungstic acid in nitrogen soluble were periodically measured to evaluate the proteolysis in the 90 d ripening,which reflected the width and depth of proteolysis.There was a linear regression relationship between all the variables and ripening(p<0.05).It can be applied to judge and predict the ripening time of Tilsit type cheese. |
