摘要: 对食品加工条件(温度、pH值)、食品中的主要组分(葡萄糖、蔗糖、淀粉、蛋白质)、及VC和苯甲酸钠等对CPP在pH8时延缓磷酸钙沉淀形成能力的影响进行了研究。其结果为:加热温度在100℃以下时,对CPP活性无影响,在pH8~9时CPP仍能延缓磷酸钙沉淀的形成;应用CPP时在蛋白质含量高、淀粉含量低的条件下较好。

Abstract: It was studied that Effct of preparing condition (temperature and value of pH) and main component (glucose,sugar,starch and protein) of food and viamin C and sodium bezoate on CPPs postponing calcium phosphate.the result of study show the temperatue was lower than 100℃ haven’t affect to CPPs;CPPs can still postpone calcium phosphate precipiating under the condition of pH8~9,it is better that applying CPPs in food wihch contains higher protein and lower starch.
