利用质构仪测量琼脂和卡拉胶凝胶特性,重点研究了Mg~(2+)、浓度和pH值对琼脂和卡拉胶凝胶强度的影响。结果表明,琼脂凝胶强度随着Mg~(2+)浓度的增加有小趋势的增加,因此可在琼脂中添加Mg~(2+),而Mg~(2+)不能使卡拉胶凝胶,浓度是影响凝胶强度的主要因素,凝胶强度随着浓度的增加而增加,随着pH先增后减。

Using texture analyzer,the gels of carrageenan and agar were measured.Special attention was pain to the influence of concentration,pH value and Mg2 ＋ ion intensity on the gel strength of the agar and carrageenan.The results showed that the gel strength of the agar have a small increasing trend with the increase of the concentration of Mg2 ＋,so Mg2 ＋ can be added to the agar.But Mg2 ＋ can not make carrageenan gel effectively,the concentration was the main factor in affecting the gel strength.This strength increased with increasing concentration,and f...
