strip Agar is colorless translucent or white to light yellow, the surface shrinkage, slightly glossy, light, soft and tough, not easy to fold, completely dry, brittle and fragile; powdered Agar is a white or yellowish scaly powder. The Agar was odorless and mild in taste. Insoluble in cold water, but can slowly absorb water, swelling and softening, can absorb more than 20 times the water. It is easily dispersed in boiling water to form a Sol, and the Sol is a neutral reaction. More than 0.1% to 0.6% of the Sol can be converted into gel at 28 to 42 °c, and will not melt below 85 °c. Not involved in human metabolism, no nutritional value.
water soaked stone cauliflower, Corynebacterium and other red algae to remove impurities, and then sulfuric acid or acetic acid under certain conditions to soak hydrolysis, and then the hydrolysis liquid is filtered, purified, the product is obtained by cooling and solidifying.
This line is derived from the slime leached and dehydrated by the stone cauliflower Gelidium amansii Lamx or several other red algae.
as an emulsion stabilizer and thickener, Agar has a strong gelling power, and its gel strength increases when it is used together with dextrin or sucrose. China's provisions for all types of food, according to the production needs of the appropriate use.
