Gelatin is manufactured by cooking animal bone, skin, ligaments, tendons and collagen of tendons by acid or alkali or boiled in water; on the other hand, agar-agar can be made by seaweed or kudzu root. Gelatin is a mixture of soluble protein in water, which is colorless or yellowish transparent chips or coarse powder, gelatin is not easy to dissolve in water, which is formed a gel under the 35 ~ 40 ℃ water (water content of 5 to 10 times its own weight), plastic melting point between 24-28 ° C, and the difference between its solubility and the solidification temperature is small, so it is easily to go bad under the influence of moisture, temperature, humidity. So it should be kept away from the high temperature and the moist place, the room temperature,ventilate and dry,evades the light for the best storing condition.Storing to cleanly weaves in the bag,preserve time is three years
