补充资料：浓缩冷冻混浊红葡萄汁
工艺流程 红葡萄→洗净→破碎除梗→加热→榨汁→除果酱→杀菌→冷却→浓缩→糖度调整→冷却→冷冻→灌装→密封→包装→检验→产品→冷冻保藏
制作方法
1.为了保持葡萄汁的混浊度，除果酱时不使用酶法处理果酱，而且直接应用自动排渣离心分离机除果酱，离心机转速为6000转/分。
2.杀菌冷却，一般采用片式热交换器，杀菌温度85℃，15秒。迅速冷却至常温。
3.浓缩冷冻混浊红葡萄汁比透明汁果胶含量高，果汁中又有许多不溶性固形物，容易产生胶化现象。所以这样的果汁浓缩一般控制果汁糖度在33°bx，浓缩比为1/3比较合适。
4.浓缩后的混浊红葡萄汁，一般用片式热交换器两级冷却，第一级通自来水冷却到20℃，第二次通冷冻水冷却到5℃左右。然后再用快速冷冻机冷到-6～7℃。
5.这种冷冻红葡萄汁一般作为原料果汁，用18立升的内表面有涂层的铁桶盛装，果汁净重20千克。注意不要装满，要考虑到冷冻时的体积膨胀。密封包装后的产品，存放在低温冷库内在-25℃冻结保藏。
产品特点 经包装保藏后其色、香、味俱佳，是理想的原料果汁。
