Uses and synthesis of Agar powder

Agar powder is a translucent white to light yellow film band or fragments, particles and powders odorless or slightly smelly, sticky and smooth taste. Agar powder can be used as gummies. Ice cream. Jelly. Ham. Gel powder. Spam. Sausage. Ketchup. Coconut sauce. Dry cheese, etc. The amount of AGAR is generally between 0.3-1.5%. Agar powder is a kind of algal gel extracted from cauffles and other red algae. It has been used in China and Japan for more than 300 years. Due to its special gel properties, Agar powder has been widely used in food, medicine, chemical industry, textile, national defense, biological research and other fields. Internationally known as "novel East Asian products".

Functions of Agar powder

1. Agar powder is used as emulsifying stabilizer and thickener. AGAR has a strong gelling ability and its gelling strength increases when used with dextrin or sucrose.
2. Thickening agent; Stabilizer; Emulsifier; Gelling agent. Agar is commonly used in confectionery, soup, pastry, pies, ice cream, yogurt, soft drinks, dairy products, etc. In beer production, it can be used as a curing agent of copper, and the protein and tannin in it are condensed and precipitated away.
3. It is used as a preparation of bacterial medium and also as a stabilizer of colored substance suspension

Application of Agar powder

Cosmetics Field: Agar is also used in the cosmetics field:

Thickener and stabilizer: Agar can be added as a thickener and stabilizer to lotions, creams, masks, shampoos, shower gels and other cosmetics to improve the viscosity, stability and skin feel of the products.

Film-forming agent: Agar has good air permeability and is not greasy after film formation. It can be used as a film-forming agent in products such as masks and isolation creams to form a protective film to prevent water loss and resist external stimuli.

Moisturizer: Agar has a certain hygroscopic and moisturizing property. It can be added as a moisturizing ingredient to moisturizing creams, masks and other skin care products to increase skin moisture and keep the skin moisturized.

Pharmaceutical Field: Agar also has certain application value in the pharmaceutical field:

Laxative: The main component of agar is polysaccharide, which is difficult for the human body to digest and absorb, but it has strong water absorption. After entering the intestine, it can absorb water and swell, increase the volume of feces, stimulate intestinal peristalsis, promote defecation, and have a laxative effect. It can be used to treat constipation. However, its laxative effect is relatively mild and is usually used for mild constipation.

Excipients for pharmaceutical preparations: Agar can be used as an excipient, adhesive, disintegrant, sustained-release material, etc., and is used in solid preparations such as tablets, capsules, and granules, as well as liquid preparations such as emulsions and suspensions. Its film-forming, thickening, and stability properties can be used to improve the appearance, taste, stability, and drug release of pharmaceutical preparations.

Oral impression materials: Agar hydrogel has good elasticity, plasticity, and hydrophilicity. It was used as a dental impression material in the early days to make dental molds, but it has now been replaced by more advanced alginate impression materials and silicone rubber impression materials.

Biomedical materials: Agar and its derivatives have also been studied in the fields of biomedical materials such as tissue engineering, drug delivery, and wound dressings, but they are still in the research and development stage and their applications are relatively limited.

Production methodprocess of Agar powder

From the related algae such as red alga, Gracilaria, etc., pre-treated with lye, washed to remove alkali, boiled with weak acidic solution, or extracted by autoclave, filtered to remove slag, solidified, dehydrated, dried and crushed. Agar powder can be prepared by freezing, thawing and drying the filtered gel
