Problems solved by technology

Although new microencapsulation methods and technologies are emerging, most of them use protein, carbohydrates and wax as wall materials. The resulting microcapsules are fragile, have little adaptability to core substances, are not pressure-resistant, heat-resistant, and have poor processability. Moreover, the particle size of the product is not uniform, so there are not many products that can be used in industrial production, and some microencapsulation processes will use toxic solvents or auxiliary materials, etc.

Embodiment 1

[0048] Example 1 According to the preparation method described in the specification, the Saccharomyces cerevisiae strain was inoculated on the PDA slant seed medium for activation for 4 hours, and then inserted into the high-sugar seed medium for 24 hours of cultivation. Then insert 10% of the inoculum into the high-sugar medium, the filling volume is 50mL fermentation broth / 250mL shake flask, the fermentation temperature is 28-32°C, the fermentation time is 24 hours, and the shaker speed is 180r / min. After centrifugation, washing, and freeze-drying.

Embodiment 2

[0049] Example 2 According to the preparation method described in the instructions, inoculate the Saccharomyces cerevisiae strains on the PDA slant seed medium for activation for 4 hours, then insert into the bean sprout seed medium and cultivate for 24 hours, then insert the bean sprouts at an inoculation amount of 10% In the culture medium, the liquid volume is 50mL fermentation broth / 250mL shake flask, the fermentation temperature is 28-32°C, the fermentation time is 24 hours, and the shaker speed is 180r / min. After centrifugation, washing, and freeze-drying.

Embodiment 3

[0050] Example 3 According to the preparation method described in the instruction manual, inoculate Saccharomyces cerevisiae strains on PDA slant seed medium for activation for 4 hours, then insert into YPD seed medium and cultivate for 24 hours, then insert into YPD according to 10% inoculation amount In the culture medium, the liquid volume is 50mL fermentation broth / 250mL shake flask, the fermentation temperature is 28-32°C, the fermentation time is 24 hours, and the shaker speed is 180r / min.

Abstract

The present invention relates to a method for preparing safe, non-toxic and property-excellent microcapsule wall material by using yeast cell. In the concrete, said invention relates to a method for culturing and processing yeast cell, and further relates to a microcapsule wall material prepared by using said method and biological microcapsule. Said method includes the following steps: making the yeast cell cultured under the proper condition be directly suspended in the autosoluble accelerating agent formed from Tween-80 or TritonX-100, hexadecyltrimethylammonium bromide, sodium lauryl sulfate, ethyl acetate, ethyl alcohol, hydrochloric acid, sodium hydroxide, potassium chloride and sodium chloride, making shaking treatment for 24-48h at 40-60deg.C, centrifugalizing, washing, freeze-drying so as to obtain the invented microcapsule wall material.

Description

technical field [0001] The present invention relates to a method of using yeast cells to prepare safe and non-toxic microcapsule wall materials, a method for cultivating and treating yeast cells, and further relates to microcapsule wall materials and biological microcapsules prepared by the method . technical background [0002] Microencapsulation technology, also known as microencapsulation, is one of the key high-tech developments in food, medicine and other industrial fields in the 21st century. Microcapsules are composed of core material and wall material, which can protect substances from environmental influences, reduce toxicity, mask bad taste, control core release, prolong storage period, change physical state for easy portability and transportation, and change physical properties to make incompatible ingredients Uniform mixing and other functions. These functions make microencapsulation technology an effective commercialization method in the industrial field, and ...
