2-(2-ethoxy-2-keto-ethyl)-1,4-dimethyl-pyrrole-3-carboxylic acid ethyl ester - Introduction
MALTOPENTAOSE, also known as maltooligosaccharide, is a polysaccharide structure composed of glucose molecules. It is the product of maltose through enzymatic hydrolysis, with special chemical properties and biological functions.
MALTOPENTAOSE is chemically insoluble in water, but can be fermented by some microorganisms (such as lactic acid bacteria). It is stable under acidic conditions, but decomposes under alkaline conditions. In addition, MALTOPENTAOSE also has a strong antibacterial effect, can inhibit the growth of some pathogenic bacteria.
MALTOPENTAOSE is widely used in the food industry. It can be used as a food additive in condiments, beverages, dairy products, pastries and other foods to increase the taste and nutritional value of food. MALTOPENTAOSE can also be used as a nutritional source of probiotics, promote the growth of probiotics, and have a beneficial regulatory effect on the intestine.
The preparation method of MALTOPENTAOSE is generally obtained by the catalytic reaction of maltose through decomposition enzyme. After the maltose is heated, the corresponding enzyme is added. The enzyme can break down the maltose into smaller molecules, including MALTOPENTAOSE.
MALTOPENTAOSE has high safety and is generally considered to be food safe. It has a slow digestion and absorption rate in the human body, does not cause a rapid increase in blood sugar, and has no adverse effects on diabetic patients. However, individual people may be allergic to MALTOPENTAOSE, and attention should be paid to possible allergic reactions when using it.
In General, MALTOPENTAOSE is a food additive widely used in the food industry. It has good chemical properties and biological functions, as well as high safety.
