Betaine includes betaine hydrochloride, betaine anhydrous, betaine monohydrate, pharmaceutical grade betaine and compound betaine. In our country in the late 1970 s gradually choose membrane separation equipment for betaine from cabbage, Organic synthesis was gradually applied to manufacturing after 2000, accompanied by betaine efficacy and role of gradually highlight, betaine demand more and more big, betaine production line has also begun to be built throughout the country. At present, China has already become the world's largest betaine production and manufacturing industrial base, the application of betaine has also been extended to feed, alcohol, food, medicine, agriculture, daily chemical plants and many other fields.

According to the "2019-2024 In-depth Investigation and Development Forecast Analysis Report of Betaine Sales Market in China" published by The New Industry Development Center, from 2014 to 2018, with the expansion of the market capacity of feed, alcohol, food, medicine, agriculture, daily chemical plants and other fields, the demand for betaine has maintained and improved the development trend. In 2018, the demand will reach 140,000 tons. In addition, with the advantages of cost in the field of betaine in China, the competitiveness in the foreign market is slowly improving, and the production and sales continue to improve. Under the trend of continuous improvement in the demand of the world market, the sales of betaine in China continue to increase, and the operation of the enterprise develops steadily.

Feed is the most critical application area of betaine. The amount of betaine added in feed is very little, but the effect is obvious, it has significant practical effect on strengthening the basic feed nutrients, improving the production characteristics of animals, ensuring the physical and mental health of small animals, saving feed costs, improving the quality of livestock and poultry. Betaine is recognized as one of the new non-toxic, harmless and pollution-free yeast feed additives. In the future, the development trend of feed industry production in China will eventually promote the development of betaine sales market and promote the capacity of betaine market.

At the present stage, the key investment of betaine project in China is concentrated in betaine hydrochloride, anhydrous betaine and other commercial fields, while the investment of compound betaine, pharmaceutical betaine and other products is relatively less. In the future, the project investment of compound betaine and pharmaceutical betaine needs to be improved.
