Abstract

The present invention discloses zinc replenisher with control released zinc and its preparation process and use. The zinc replenisher is zeolite containing active zinc in 1.5-10 wt%. The preparation process includes the adsorption and ion exchange reaction between zinc salt and zeolite, filtering, drying and crushing to obtain zeolite containing active zinc. Supporting zinc onto zeolite, which possesses excellent biocompatibility, excellent gastrointestinal mucous membrane affinity, regular pore canal structures and cage spaces, high surface activity and great specific surface area, can obtain controlled releasing of zinc and raise utilization of zinc. The control released zinc preparation may be used as zinc replenisher for human body and animal.

Description

technical field [0001] The invention relates to a zinc supplement of controlled and sustained release type zinc, a preparation method and application. Background technique [0002] Zinc is an essential trace element for the body. It has been proven that zinc participates in the composition of more than 300 enzymes and functional proteins in animals. It not only participates in the metabolism of DNA, RNA, proteins, sugars, lipids, vitamins and minerals in animals, And it is related to the function and activity of insulin cord, glucagon, prostatic cord, gonadotropin, etc. In addition, zinc is also a component of many functional proteins such as metallothionein, nucleoprotein, receptor, etc., so zinc has a wide range of physiological and biochemical functions. Zinc nutrients can be divided into: 1) Inorganic zinc: including zinc sulfate, zinc oxide, zinc carbonate, zinc sulfide, etc. The typical representative of inorganic zinc is zinc sulfate. According to the "Chinese Medic...
