Those whose gel strength is lower than 1000 belong to agar powder, which can be melted in bubbles of 95 degrees; those whose gel strength is higher than 1000 belong to agar powder and Gracilaria, which need boiled water to be completely melted. Gracilaria has good elasticity, low freezing point and good hardness. When the dosage of Gracilaria is large, the dosage of Gracilaria is small, and the ratio of water to powder is 400 1, it can be made into jelly and solidified at 42 degrees. You have a scale test for these characteristics. Qingdao Agar Manufacturing Co., Ltd. replied.
