Embodiment 1

[0022] Example 1 The impact of the type of maltodextrin on the stability of tributyrin microcapsules

[0023] The preparation process of tributyrin powder oil is carried out as follows:

[0024] (1) Add maltodextrin and cyclodextrin into distilled water, heat in a water bath at 50-80°C and mix evenly;

[0025] (2) Add tributyrin and emulsifier to the mixed solution obtained in (1), fully stir;

[0026] (3) The mixture obtained in (2) is sheared intermittently for 2 to 5 minutes at 8,000 to 20,000 rpm (increasing the speed step by step) with a high-speed shearer, and then homogenized for 2 to 3 minutes with a high-pressure homogenizer at a pressure of 30 to 40 MPa. times, and finally carry out spray drying to obtain tributyrin microcapsule powder product. The operating parameters of the spray drying are as follows: the inlet air temperature is 180-185°C, the outlet air temperature is 85-95°C, and the feed flow rate is 20-22mL / min.

Abstract

Belonging to the technical field of grease microcapsulation, the invention discloses a tributyrin microcapsule with maltodextrin and cyclodextrin as the wall material. The preparation process includes: adding maltodextrin and cyclodextrin into distilled water, conducting water bath heating at 50-80DEG C, and mixing the substances evenly, then adding tributyrin and an emulsifying agent, and fully stirring the substances evenly; and carrying out shearing, homogenizing and spray drying on the obtained mixture so as obtain a tributyrin microcapsule powder product. The method adopted by the invention has the characteristics of simple process and convenient operation. The prepared tributyrin microcapsule powder has the characteristics of small peculiar smell, and good stability and solubility, obviously improves the defects of peculiar smell, insolubility in water, poor fluidity and the like in tributyrin, and expands the application of tributyrin.

Description

technical field [0001] The invention relates to tributyrin microcapsules with maltodextrin and cyclodextrin as wall materials, and belongs to the technical field of oil microencapsulation. Background technique [0002] Butyric acid is a short-chain fatty acid that exists in the intestines. It has the functions of providing energy for intestinal mucosal cells, improving the morphology and structure of the small intestine, and regulating the balance of intestinal microorganisms. However, due to the freeness, volatility and special odor of butyric acid, It is not conducive to the actual production application. As the precursor of butyric acid, tributyrin is composed of three molecules of butyric acid and one molecule of glycerin, and its chemical formula is C 15 h 26 o 6 It is a white and nearly oily liquid, easily soluble in organic reagents such as ethanol, which overcomes the defects in the physical and chemical properties of butyric acid, and also has the functions of im...
