The main purpose of agar powder:
1. Agar powder is usually used as a raw material for biological culture medium for scientific experiments and research.
2. Because agar powder is a harmless sugar component, it is often used as a drug carrier in the medical field.
3. In the food processing industry, agar powder is often used as a thickener and coagulant. It is used to improve and increase the viscosity of foods, maintain the color, aroma, taste and stability of liquid foods and jelly foods, improve the physical properties of foods, and make foods smooth and palatable.
4. Suspending agents and emulsifiers used in the production of the beverage industry can also be used to uniformly disperse the particles in the beverage.
Private production and industrial production of agar:
1. The folk production method of agar is relatively simple. It is made by heating and dissolving the raw materials, filtering and slowly solidifying them. It is usually placed on a relatively dry field or on a high platform. After laying a clean straw mat, place the agar solution to cool it down completely. The production cycle is 2 weeks, and the production is usually carried out during the three months of December to February, the most severe cold of each year.
2. Industrial production of agar powder is much more advanced, and it is usually made in a factory with complete sanitary management conditions. After heating and dissolving the raw materials, the agar component is extracted from the raw materials, filtered, and cooled. It is usually put in a large freezer and frozen, and the powder is made by removing water through a dryer.
