Galactomannan (GM) is widely used in many fields, mainly including food, medicine, oil production, etc.
Food field Thickener: Galactomannan has good thickening properties, which can increase the viscosity of food and improve the taste and texture of food. Therefore, it is widely used in the preparation of foods such as yogurt, jam, and salad dressing. Stabilizer: Galactomannan has good stability and can effectively stabilize suspended particles and proteins in food to prevent precipitation and stratification of food. Therefore, it is widely used in the preparation of foods such as juice, beverages, and dairy products. Emulsifier: Galactomannan has good emulsifying properties, which can reduce the surface tension of the oil-water interface, promote oil-water mixing, and improve the emulsification stability of food. Therefore, it is widely used in the preparation of foods such as margarine and mayonnaise. Nutritional enhancer: Galactomannan has low calorie and fat content and can be added to food as a nutritional enhancer to meet the nutritional needs of special groups of people. For example, it can be used as a food additive for diabetic patients to reduce the blood sugar response of food. Antibacterial agent: Galactomannan has antibacterial properties, which can inhibit the growth and reproduction of bacteria in food and extend the shelf life of food. Therefore, it is widely used in the preparation of canned food, condiments and other foods. Medical field Galactomannan is also widely used in medicine and clinical fields. It has the functions of lowering blood sugar, preventing constipation, regulating insulin levels, improving intestinal bacteria, lowering cholesterol, and preventing cancer. In addition, galactomannan can also be used as a drug carrier to improve the stability and bioavailability of drugs. Oil recovery field In oil recovery, galactomannan and its modified products such as carboxymethyl galactomannan and hydroxyethyl galactomannan are used as thickeners, drag reducers, stabilizers for foams and emulsions. The modified galactomannan exhibits better performance in oil recovery and can improve oil recovery efficiency and economic benefits.
