Problems solved by technology

Although tributyrin has many good properties and better potential application value than butyric acid and its salts, it also has certain defects: there is still a certain odor, poor fluidity, extremely difficult to dissolve in water, and easy to dissolve in water. Rancid oxidation, not conducive to transportation and storage

Abstract

The invention discloses a method of utilizing a Tween emulsifier to prepare microcapsule tributyrin and belongs to the technical field of oil microencapsulation. In the method, by taking cyclodextrin,dextrin and the like obtained after tributyrin is acted on starch or maltodextrin by using enzyme as wall materials, the wall materials are embedded with Tween as an emulsifier to prepare microcapsule tributyrin powder, peculiar smell of the tributyrin is removed, the stability and the solubility of the tributyrin are improved, and the method has an important significance to wide application of the tributyrin in the aspects of livestock feeds and breeding industry.

Description

technical field [0001] The invention relates to a method for preparing microcapsule tributyrin by using a Tween emulsifier, and belongs to the technical field of oil microencapsulation. Background technique [0002] Short-chain fatty acids (such as acetic acid, propionic acid, butyric acid, isobutyric acid, valeric acid, etc.) are important energy supplies for colon and small intestinal epithelial cells, and play an important role in maintaining the normal function of the large intestine and promoting the consumption and absorption of nutrients. Among them, butyric acid is the most effective in this regard, so it and its salts are potential substitutes for antibiotic feed additives. However, butyric acid and its salts have a strong cheese-like rancid odor, which brings a lot of inconvenience to operators during feed processing, and also affects the feed intake performance of poultry and livestock. [0003] Tributyrin (tributyrin, C 15 h 26 o 6 ), which is formed by ester...
