Embodiment

[0017] Embodiment: choose gelatin (A), gum arabic (B), maltodextrin (C), and β-CD (D) 4 kinds of wall materials that are most commonly used in oil microencapsulation to carry out compounding at a ratio of 1:1. Mix and emulsify homogeneously under the conditions of 1:4, solid content concentration 20%, emulsifier 0.6% (monoglyceride: sucrose ester = 1:1), take the sensory properties of the emulsion as the evaluation index, and comprehensive analysis to determine the ideal Composite wall materials. The experimental results show that the coixenolide emulsion obtained by compounding gum arabic and maltodextrin has no precipitation and only a small amount of slick oil on the surface. The emulsification effect of coixene is good, and it is suitable for microencapsulation. Further experiments confirmed that maltodextrin and arabic Glue is used to form a composite wall material in a ratio of 3:1; a composite emulsifier is composed of sucrose ester and monoglyceride in a ratio of 1:1; ...

Abstract

The invention discloses a preparation method for microencapsulating coixenolid, which comprises the following steps of: adding a composite emulsifier into the mixed solution of the coixenolid and a composite wall material to form emulsion, adding water, heating the mixed solution to dissolve the emulsion, uniformly stirring the mixed solution, performing emulsification in a thermostatic water bath of a colloid mill, performing emulsification and homogenization in a homogenizer, and performing spray drying and sieving to obtain the finished product. The preparation method can reduce the degree of influence of an external environment on the coixenolid, keep the original activity of the coixenolid, improve storability and operability and cover peculiar smell, and simultaneously, is low in cost, widely applicable and simple in process.

Description

technical field [0001] The invention belongs to the technical field of food processing and medicine, and in particular relates to a preparation method of coixenolide microencapsulated. Background technique [0002] Job's tears ( Coix lacryma-jobi L. ) belongs to the Gramineae family ( Gramineae ) Maize Coix genus, native to tropical and subtropical regions of Southeast Asia, as well as China's Guangxi or Yunnan-Guizhou Plateau. According to archaeological data, Job's tears is one of the earliest gramineous plants developed and utilized by the Chinese nation, with a cultivation history of at least 6,000 years. It is an annual or perennial herb plant that likes warm and humid climates, has strong adaptability, and has the characteristics of waterlogging resistance, drought resistance, and wind resistance. my country's Coix coix is ​​very rich in resources and is widely planted in various provinces in the north and south; it is cultivated in areas with an altitude of 35-2500...
