Problems solved by technology

At the same time, cysteamine hydrochloride is very easy to oxidize and absorb moisture, which leads to the rapid oxidation of cysteamine hydrochloride during the granulation, coating process and product placement of the finished product, which affects the use effect of the product
At present, the technical process adopted by cysteamine hydrochloride products on the market is physical granulation and coating. Due to the relatively low ratio of sustained-release materials and coating, palatability and stability problems exist at the same time.

Abstract

The invention discloses a granulating coated slow release product of cysteamine hydrochloride and a preparation method thereof. The product is obtained by taking cysteamine hydrochloride, corn starch, vitamin C, powdered glucose, stearic acid and 85wt percent phosphoric acid solution as raw materials through the processes of heating for dissolving, millard reaction, stabilization treatment, atomized granulation, hardening waterproof coating, enteric coating, drying, sieving and the like, wherein the content of the cysteamine hydrochloride in the product is more than or equal to 30.50 percent and the water content ranges from 0 percent to 8.0 percent. The method thoroughly eradicates the odor of the cysteamine hydrochloride, the product has the fragrance of bulked corn, and the glucose added in the millard reaction can conduct physical coverage and cause the cysteamine hydrochloride to be slowly released, thus increasing the palatability of products. The addition of glucose in full-price materials not only does not affect feed intake, but also can increase the feed intake. In the process of technological treatment and storage of the products, the content of cysteamine hydrochloride is stable.

Description

technical field [0001] The invention relates to cysteamine hydrochloride, in particular to a cysteamine hydrochloride granulated and coated slow-release product and a preparation method thereof. Background technique [0002] Cysteamine hydrochloride can inhibit the secretion of somatostatin in animals, promote animal growth, increase feed-to-meat ratio and protein deposition rate. At present, cysteamine hydrochloride products mainly include powder and granular products. [0003] Because cysteamine hydrochloride itself has a strong odor and bitter taste, it has a great impact on animal feed intake. At the same time, cysteamine hydrochloride is very easy to oxidize and absorb moisture, which leads to the rapid oxidation of cysteamine hydrochloride during the granulation, coating process and product placement of the finished product, which affects the use effect of the product. At present, the technological process adopted by cysteamine hydrochloride products on the market is...
