Solid hydrogen peroxide sustained release preparation and preparation method thereof

Abstract

The invention relates to a sustained release preparation and a preparation method thereof and particularly discloses a solid hydrogen peroxide sustained release preparation and a preparation method thereof. The solid hydrogen peroxide sustained release preparation is characterized by being prepared by taking a solid hydrogen peroxide adduct as a main agent and adding solid weak acid, water absorbing materials and auxiliaries according to a certain proportion, wherein the weight percentages of all the components are as follows: 0.1-99% of the solid hydrogen peroxide adduct, 0.1-98% of the solid weak acid, 0-98% of the water absorbing materials and 0-98% of the auxiliaries. The solid hydrogen peroxide sustained release preparation and the preparation method thereof which are provided by the invention have the beneficial effects that: the solid hydrogen peroxide sustained release preparation can be conveniently used for food sterilization and fruit and vegetable preservation and can be stored for a long term and the solid hydrogen peroxide adduct releases hydrogen peroxide when encountering water and is easy to control; the release speed and the sustained-release period of the hydrogen peroxide can be regulated according to needs; the sustained release preparation is simple in production and has small investment and low cost; and the solid hydrogen peroxide sustained release preparation is a solid powdered product and can be conveniently stored and transported.

Description

(1) Technical field [0001] The invention relates to a sustained-release agent and a preparation method thereof, in particular to a solid hydrogen peroxide sustained-release agent and a preparation method thereof. (2) Background technology [0002] Hydrogen peroxide is an inorganic substance, which is a strong oxidant, and acidic conditions are conducive to the stability of hydrogen peroxide. Hydrogen peroxide is a high-efficiency disinfectant and bactericide, widely used in wound disinfection, environment, food disinfection and other fields. [0003] Hydrogen peroxide has been used in the field of disinfection for more than 100 years, but there are very few successful examples in the food processing industry and fruit and vegetable preservation. To the effect of fresh-keeping requirement; The 2nd, the preparation device of hydrogen peroxide vapor is inconvenient to use, and cost is high. The above reasons bring inconvenience to the production, storage, transportation and u...

AI Technical Summary

Problems solved by technology

The above-mentioned patents have improved the transportation, use, and safety of hydrogen peroxide, but none of them has solved the problem of quantitative release and stability of hydrogen peroxide, which limits the application of hydrogen peroxide and brings inconvenience to users.
