Chelated-Mg composite feed and preparation method thereof

Abstract

The invention relates to a chelated-Mg composite feed and a preparation method thereof. The chelated-Mg composite feed is prepared by processing the following raw materials in parts by weight: 20-30 parts of defatted rice bran, 10-20 parts of corn flour, 10-15 parts of sweet potato vine powder, 10-20 parts of wheat bran, 15-30 parts of soybean cake powder, 30-40 parts of sea cucumber intestine extract chelated Mg, and 4-6 parts of bacillus subtilis. A preparation method of the sea cucumber intestine extract chelated Mg comprises the following steps: (1) sea cucumber intestine pretreatment; (2) sea cucumber intestine homogenizing; (3) primary enzymolysis; (4) secondary enzymolysis; (5) ultrafiltration; (6) nanofiltration; and (7) chelation. The prepared chelated-Mg composite material capable of promoting digestion and assisting growth is rich in nutritional ingredient, easy to absorb and utilize, high in absorption and utilization rate, low in contents of impurities and heavy metals, and high in nutritive value, and is capable of not only replenishing magnesium element, but also replenishing various nutritive elements from sea cucumber intestines.

Description

technical field [0001] The invention relates to a chelated magnesium compound feed and a preparation method thereof. Background technique [0002] Sea cucumber is one of the precious seafood. It contains more than 50 kinds of nutrients that are beneficial to human physiological activities. Among them, the protein content is high, and the trace elements are rich in types. It also has the functions of anticoagulation, antitumor, antibacterial, antiviral and improving immunity. In recent years, there are more and more enterprises processing sea cucumbers. The nutrients contained in sea cucumber intestines, which are leftovers in the process of sea cucumber processing, are no less than those in the body wall. The vanadium content of its dry sausage is 12 parts per million, about 3 times higher than that of its body. It has the effect of warming the middle, tonifying deficiency and relieving pain, and can treat gastric and duodenal ulcers. [0003] The utilization of sea cucum...

AI Technical Summary

Problems solved by technology

However, this kind of capsule product does not do biological treatment to sea cucumber intestines, the absorption and utilization rate is low, and the nutritional value is greatly reduced

In addition, there are still problems in the processing of raw materials: the efficiency of manual desilting of sea cucumber sausages is low, the sediment is not thorough, and the desalination is not thorough after washing with water, resulting in the problem that the content of heavy metals and salt in the product exceeds the standard.
