请教果冻膨胀问题 [复制链接]

Please find attached formulation to make jelly beads drink.
"Gum" means Sodium Alginate.
We make the Jelly beads first, and then we drop this into the 'setting solutions' using a pippette, then the jelly becomes hard because of the diffusion setting .
after that we washed the jelly beads and then put it in the storage solution.
To make a drinking jelly we use the last formula.
But if we make jelly with jelly beads inside,then we make a jelly dessert first , and put the jelly beads inside after water dessert jelly ready.
if we put the jelly beads inside the 'fluid gel' the swelling is not happen, it is only happen inside water dessert jelly based on carrageenan.

      楼主,大致看了你帖子的内容,似乎你的题目应该改为“海藻酸钠和钙盐形成不可逆胶在水溶液中为何会崩解”而非果冻的膨胀问题。另外最好用中文问问题,因为这里很多网友看长篇英语可能会头痛!

      楼主问题的大致意思是海藻酸纳和钙交联形成海藻珠储存在卡拉胶凝冻的水溶液中一段时间后为何会发生崩解(海藻珠烂开,楼主说是果冻膨胀),楼主,不知我的理解是否正确?

      海藻酸钠和钙盐形成不可逆胶后,有报道说将海藻珠浸在一定浓度的硼砂溶液中能加强它们的交联强度,(似乎增加的幅度也不大),但楼主的海藻珠是用于做食品的,故该方法并不可行。且即使用硼砂溶液处理了,也只是增加一点强度,并不能完全避免它在水溶液中的崩解。

      至于它储存在卡拉胶溶液中为何出现这种现象则可以从两方面解释:A.fluid gel中含有乳酸钙,能有效补充海藻珠中逃逸的钙离子,故而不易出现崩解;B.卡拉胶的凝胶冻中的阳离子(K+)和海藻珠中钙离子存在置换或不能有效阻止钙离子逃逸。

      出现这种问题并不要紧,其实有很多种方法可以解决这问题的。你稍微转换一下思路就可以。查我以前发的一些贴子里就有所提到的解决办法。

使用铝盐也有一些帮助

楼主,你若要加强海藻珠的强度,海藻酸钠浓度、pH、温度、溶涨时间、凝固剂、金属离子、乙醇以及海藻酸钠以其它食用胶的协同作用对海藻酸钙凝胶拉伸强度、弹性、脱水性等特性均有影响。

你可以按下述条件试验一下:

海藻酸钠浓度为1.5%,pH 为4~5,温度为50~C一60~C,溶胀时间为45min,采用乳酸钙,加入硫酸铝;

另外,海藻酸钠与瓜尔豆胶、明胶、p一环状糊精、
EDTA的协同增效作用有利于海藻酸钙凝胶的形成。

还有些其它的方法可以不耽搁你的生意,

这是我的一个国外客户做果冻的配方,我不知道问题出在哪。非常感谢指教!回头我再调试看看结果如何。谢谢!
