Curdlan powder

What is Curdlan powder?

Curdlan powder is a β-1,3-glucan, a high molecular polymer composed of glucose. It contains the residue of β-(1,3)-glucose and can be heated in the water-like suspension it forms to form an elastic colloid substance called curdlan gum. Curdlan has a β-triple helix structure. When heated into high-strength gel, it is a right-handed 6-fold 3-stranded helix that can form a stable hard rod structure. It is a water-insoluble polysaccharide that is insoluble in general organic solvents and soluble in alkaline solutions. It is a water-insoluble glucan composed of β-(1→3)-glycosidic bonds produced by microorganisms. It is a general term for polysaccharides that can form both hard and elastic thermally irreversible gels and thermally reversible gels after heating their suspensions.

Source:

It is a class of molecules composed of polysaccharides that can form gel structures. They have rich biological activities and can be extracted from animals, plants and microorganisms. According to different sources, they can be divided into animal-based, plant-based and microbial-based gel polysaccharides.
Animal sources mainly come from animal connective tissues and internal organs, such as fish skin, sea cucumbers, and clam shells. Plant sources come from seeds, fruits, leaves and other parts of various plants, such as seaweed, xylan, etc. Microbial sources are synthesized by microorganisms, such as mycelium and extracellular polysaccharides. These curdlans have similar basic structures, but their biological activities and effects are different.

Physiological functions:

Due to its unique macromolecular structure and its special triple helix advanced three-dimensional molecular structure, it has many unique physiological functions. It can improve the body's immunity. Curdlan with β-glucan glycosidic bonds also has a good health care effect. It is not absorbed in the digestive tract and has no nutritional value. It does not cause weight gain after consumption and can be used as dietary fiber.
Curdlan (CUR), a triple helical polysaccharide, is a type of linear β-(1,3)-D-glucan. It was first obtained by fermentation of Alcaligenes faecalis and approved by the US Food and Drug Administration as a food additive. Its excellent thickening and water retention properties make it widely used in the field of food processing.

Formation:

Two different gels can be formed depending on the heating temperature. When its aqueous dispersion (more than 2%) is heated to 54~80℃ and then cooled to 40℃, a thermoreversible low-strength gel can be formed. When it is reheated to 70℃, the gel will dissolve again. This property is similar to agar. If the coagulated polysaccharide is heated to above 80℃ (80~130℃) for a few minutes, a heat-irreversible high-strength gel is formed, which will not dissolve when reheated after cooling to room temperature. The heat-irreversible gel formed is brittle and hard at room temperature. The hardness decreases when heated and steamed, but the elasticity does not decrease. It will not dissolve or become soft after long cooking.

Influencing factors:

1. Concentration
As the concentration increases, its strength increases. From about 3%, the gel strength rises sharply, which is higher than the strength of agar at the same concentration. Its gel properties are between the brittleness of agar and the ductility of gelatin.
2. pH
It has strong adaptability to pH and has good gel formation in the range of pH2~10.
3. Inorganic salts
Various inorganic salts have almost no effect on gel strength, but Na2B407 can significantly enhance gel strength.

Effects and functions

1. Antioxidant effect
It has a strong antioxidant effect, which can remove free radicals and reduce cellular oxidative stress and damage. Studies have shown that its antioxidant activity exceeds that of vitamin C and vitamin E, and has potential for the prevention and treatment of oxidative stress-related diseases.
2. Immunomodulatory effect
It can enhance the function of the immune system, regulate the activity of immune cells and the level of secreted immune factors. They can increase the activity of macrophages, T cells and B cells, promote the synergistic effect of cellular immunity and humoral immunity, and thus enhance the body's resistance to pathogens.
3. Hypoglycemic effect
It has certain therapeutic potential for diabetes, and can reduce blood sugar levels by improving insulin sensitivity, inhibiting intestinal sugar absorption, and reducing liver glycogen synthesis. Studies have shown that some gelatin has a hypoglycemic effect comparable to that of commonly used antidiabetic drugs, and has good safety.
4. Cardiovascular protection effect
It has a certain ability to protect the cardiovascular system, can reduce blood lipids, inhibit platelet aggregation, and regulate endothelial cell function. They can prevent and treat cardiovascular diseases such as hypertension and hyperlipidemia, and reduce the occurrence of cardiovascular and cerebrovascular accidents.

Application areas:

1. Pharmaceutical field
It can be used for the prevention and treatment of diseases, such as antioxidants, anti-tumor agents, hypoglycemic drugs, etc.
2. Health care products
It can be used as an important ingredient in health food to enhance the body's resistance and immune function.
3. Cosmetics
It can be used as an active ingredient in skin care products to moisturize the skin and delay skin aging.
In addition, it can be used as a stabilizer, thickener and emulsifier in food processing to enhance the texture and stability of food. In environmental protection, it can be used in wastewater treatment, soil remediation and other aspects to reduce pollutant emissions. In the field of biotechnology, it can be used in cell culture, genetic engineering and other aspects to promote the progress of biotechnology.
