| 摘 要： | 考察了不同酸度、钙质量分数调节后复原乳酶凝胶的质地特性,并对其质地变量进行了主成分分析。结果表明,不同工艺处理样品间的差异可以清晰地表现在两个新变量中。酸度、钙质量分数调整可对凝胶的表观黏度和持水力产生很大影响。此外,通过对照分析可以发现,不同前处理的复原乳样品具有与原料乳相近的凝胶特性。

| Abstract: | Whey protein is of the nutritional value.The nutritional value and yield of products could increase when whey protein is integrated into cheese.The textural properties of rennet gel produced from the reconstituted whole and skim milk powder after pre-treatments by adjusting calcium concentration and pH were investigated.With the principle component analysis for textural variables,the differences in the new components were clearly observed among the pre-treatments.These pre-treatments showed great effects on... |
