Pharmaceutical DextrinIt is a dietary fiber processed from starch as a raw material. According to its solubility, dietary fiber is divided into soluble and insoluble. Dietary fiber is an indispensable nutrient for human beings, with physiological functions such as improving gastrointestinal function, regulating blood sugar and fat metabolism, lowering serum cholesterol, and promoting mineral absorption. Soluble dietary fiber is divided into high-molecular and low-molecular soluble dietary fiber according to the degree of polymerization. So, let's learn about the preparation methods and processes of pharmaceutical dextrin!

　　Pharmaceutical dextrin is a representative low-molecular soluble dietary fiber. It is not digested and absorbed by the human body and directly enters the large intestine, exerting the physiological function of dietary fiber. Moreover, dextrin molecules contain -1, 2 and -1, 3 (glucosidic bonds), and some reducing ends have intramolecular dehydration-produced glucans and -1, 6 glucosidic structures. It also has good processing stability, such as low sweetness, low viscosity, low calories, low browning, high solubility, acid and alkali tolerance, high temperature resistance, freezing resistance, and preservation resistance. Therefore, resistant dextrin, as a raw material for new dietary fiber, is widely used in beverages, dairy products, baked foods, noodles, meat products, seasonings, infant foods, health products, and special foods.

　　Pharmaceutical DextrinIt can be made from wheat starch and corn starch, and is a low-molecular soluble dietary fiber. A white to light yellow powder, it is a low-calorie glucan refined by industrially extracting and processing the indigestible components of baked dextrin. It has a slightly sweet taste, low water solution viscosity for dextrin, and little change in viscosity due to changes in shear rate and temperature. It has no other peculiar smell, good water solubility, a 10% aqueous solution is transparent or light yellow, and a pH of 4.0~6.0. It has broad development prospects in the food industry. Pharmaceutical dextrin has low calories, heat resistance, acid resistance, and freeze resistance, and can be used as a raw material for low-calorie soluble foods.

　　Key elements for pharmaceutical dextrin technology:

　　Therefore, the purpose of this invention is to provide a method for producing resistant dextrin.

　　In order to solve the above problems, this invention provides a method for producing resistant dextrin, which includes the following steps:

　　Step S1: After oxidizing corn starch for one and a half hours, pre-drying is performed to reduce the water content to less than 5%;

　　Step S2: Then, adjust the pH to 5.5-6.5 for gelatinization, increase the temperature to 180-250, maintain this temperature for one and a half hours at a constant temperature, and obtain crude dextrin;

　　Step S3: Add 1 ton of water to every 500 kg of crude dextrin, cool to 100-150, and maintain the temperature for 45 min.

　　Step S4: Add 1% of amylase to the mixture in Step S3, cool to 70-90, and maintain the temperature for 20 min;

　　Step S5: The dextrin processed in Step S4 is further filtered, concentrated, and precipitated;

　　Step S6: The slurry processed in Step S5 is placed in a spray drying tower for drying. After bacterial examination, resistant dextrin is immediately obtained.

　　The above is the preparation method and process of pharmaceutical dextrin. If you need to know more, please feel free to contact us!
