AI Technical Summary

Benefits of technology

This patented technology provides a new type of nanoencapace that solves problems with existing methods such as solvents or other chemical agents while also being easy to prepare without damaging them over time. It uses enzymes liketransglucosidases (TG) which helps create small particles called betacylates. These tiny particles are very effective because they don't harm any pigments on their surface but only work properly under specific circumstances where there may be heat exposure. They stay evenly distributed throughout this matrix made up by binder materials like plasterboard panels. Overall, these technical features make it easier than previous ways to produce high quality products containing quantum dots.

Problems solved by technology

This patented technical problem addressed in this patent relates to improving the quality of perfume compositions while maintaining durable shelf life without adding too much weight (weight). Current techniques such as emulsification require high temperatures, making them difficult to use at home or during travel. Additionally, current methods involve complicated processes involving multiple steps like mixing ingredients together, leading to low efficiency and potential issues associated therewith.

Embodiment 1

[0025] A styryl acetate nanocapsule is prepared by using a composite coacervation method with gelatin / gum arabic as the wall material, styryl acetate as the core material, Tween 20 as the emulsifier, and transglutaminase as the curing agent. The amount of gelatin, gum arabic, styroyl acetate, Tween 20 and transglutaminase used is calculated by mass ratio, i.e. gelatin: gum arabic: styroyl acetate: Tween 20: transglutaminase is 1:1: 2:2:0.25, its preparation process specifically includes the following steps:

[0026] (1) Dissolve 0.5 g of gelatin and 0.5 g of gum arabic in 100 ml of water respectively to obtain a gelatin solution with a mass percentage concentration of 0.5% and an aqueous solution of gum arabic with a mass percentage concentration of 0.5%;

[0027] (2) Add 1.0 g of core material styroyl acetate and 1.0 g of emulsifier Tween 20 to the aqueous solution of gum arabic with a concentration of 0.5% by mass obtained in step (1), and perform homogeneous emulsification w

Abstract

The invention discloses an acetic acid styracin nanometer capsule and a preparation method thereof. The acetic acid styracin nanometer capsule is prepared from gelatin/gum arabic as a wall material, acetic acid styracin as a core material, tween 20 as an emulsifying agent, and glutamine aminopherase as a curing agent by using a composite coacervation method, and in the process of the preparation, the quantity of the gelatin, the gum arabic, the acetic acid styracin, the tween 20 and the glutamine aminopherase are computed in a mass ratio of 1:1:1-2:1-2:0.25. The acetic acid styracin nanometer capsule has favorable storage stability and heat stability, and can durably and effectively control the release of the core material, wherein the average particle diameter is 168.48nm-211.67nm, and the particle size distribution coefficient is 0.132-0.154. The acetic acid styracin nanometer capsule can be used in the fields of spice, essence, foods, cosmetics, detergents, and the like.
