Example Embodiment

[0026] Example 1 The effect of adding Tween on the preparation of microcapsule tributyrin

[0027] The preparation process of microcapsule tributyrin is carried out according to the following steps: take corn starch milk with a mass concentration of 200g / L as raw material, add 2U / (g starch wet base) cyclodextrin glucosyltransferase and liquefy at 90℃ After cooling to 45°C for 30 minutes, add 2U / (g starch wet base) cyclodextrin glucosyltransferase for cyclization at 45°C for 12 hours. After the reaction, add tributyrin. The ratio of the added amount to the mass of corn starch is 0.50:1, and tributyrin is mixed with ethanol in a mass ratio of 3:1 in advance. Add Tween 20 emulsifier to the above solution for mixing. The addition amount of Tween 20 and the mass ratio of corn starch are 0.3:1. The high-speed shearing machine is gradually increased at 8000 to 20000 rpm for 2 to 5 minutes. The obtained emulsion is homogenized to obtain a uniform and stable emulsion, the homogenization ...

[0041] Example 3 Effect of Tween Type on the Preparation of Microcapsule Oil

[0042] The preparation process of microcapsule tributyrin is carried out according to the following steps: take corn starch milk with a mass concentration of 200g / L as raw material, add 2U / (g starch wet base) cyclodextrin glucosyltransferase and liquefy at 90℃ After cooling to 45°C for 30 minutes, add 2U / (g starch wet base) cyclodextrin glucosyltransferase for cyclization at 45°C for 12 hours. After the reaction, add tributyrin. The ratio of the added amount to the mass of corn starch is 0.5:1, and tributyrin is mixed with ethanol in a mass ratio of 3:1 in advance. Add Tween emulsifier to the above solution for mixing, the addition of Tween and the mass ratio of corn starch is 0.3:1, and the high-speed shearing machine is gradually increased at 8000~20000rpm for 2~5min of the above solution, and then the obtained The emulsion is homogenized to obtain a uniform and stable emulsion, the homogenization p...

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...
