Measurement Significance: The betaine is a quaternary water-soluble alkaloid distributed in animals and plants and microorganisms. It is an oxidative product of choline in biological body and enhances immunity.Force, lower blood fat, antioxidant, anti-tumor, and can be used as a methyl donor, participate in promoting animal protein and fat metabolism, enhances appetite, alleviating stress, regulating osmotic pressure, stable vitamin, and other biological effects, chemical, medical, Food additives have a wide range of applications.

Determination Principle: The beet base has a precipitate in a reactive reaction under strong acid conditions, and the precipitate is dissolved with acetone to form a red solution, and there is a characteristic absorption peak at 525 nm, and the absorbance value at 525 nm can be calculated.S product's betaine content.

Required instruments, consumables: balance, centrifuge, visible spectrophotometer / enzyme symbol, trace quantine-based cupping / 96-well plate, methanol, ether, hydrochloric acid, and distilled water.
