3.6 复合稳定剂试验
❖ 2.4.4 杀菌
❖ 在杀菌锅中将料液加热至85℃,保温20min。
❖ 2.4.5 冷却、老化
❖ 将均质后的料液迅速冷却至2~4℃进行老化, 12~24h。提高料液黏度,增加产品稳定 性和膨胀率。
❖ 2.4.6 凝冻、搅拌
❖ 将老化成熟后的物料进入冰淇淋机凝冻搅拌,使产品得到合适的膨胀率。使其中的冰晶 微细均匀。

Abstract
❖ Chinese mushroom has the characteristic of high protein,low fat,rich in polysaccharide,
❖ and having various of amino acid and vitamin. Being mixed into icecream can make it helpful to human health. We have comfirmed that the best addition amount of chinese mushroom juice is 40%,milk 6%,emulsifer 0.3% according to the orthogonal test of product ingredient and composite stabilizer. The best ratio for composite stabilizeris CMC-Na0.15%、gelatin 0.4%、xanthan gum 0.15%.
