Abstract

The invention discloses a preparation method of a ferrous saccharose complex. The preparation method comprises the steps of obtaining a ferrous saccharose solution through complex reaction of saccharose and ferric salt; cooling and filtering to obtain filter residues and a filter liquor; adding ethanol water into the filter liquor to precipitate the complex; centrifugally pumping and filtering precipitates; vacuum drying to obtain a pure ferrous saccharose complex product; detecting ferric ion concentration of the filter residues; continuously adding the saccharose and ferrous salt according to the molar ratio of the saccharose to ferric ions being 1 to 4; returning the centrifugally pumped and filtered waste water into a reaction kettle so as to be used as a mother liquor for dissolving the saccharose, and carrying out circular reaction to continuously generating ferrous saccharose. According to the process for preparing the ferrous saccharose provided by the invention, the resource is not wasted, the production cost is reduced, and the production efficiency is improved. The obtained ferrous saccharose has the advantages of safety, high efficiency and high cost performance, and can be applied in production of an animal feed with comprehensive nutrition.

Description

technical field [0001] The invention relates to a complex, especially a sucrose iron complex and a preparation method thereof, and discloses the use thereof. Background technique [0002] Nutritional and physiological functions of iron: 1. As a carrier and enzyme component: iron participates in the composition of hemoglobin and myoglobin, and is responsible for the important role of oxygen and carbon dioxide in the carrier. In addition, iron is directly involved in the composition of cytochrome oxidase, peroxidase and xanthine oxidase. Divalent or ferric iron ions are indispensable activating factors for various enzymes that activate carbohydrate metabolism; 2. Participate in protein synthesis and energy metabolism: the content of iron in animals directly affects the content of phosphorus. The synthesis of DNA will be inhibited due to phosphorus deficiency, and the mitochondria and microsomes in tissue cells will be abnormal. In addition, iron, as a component of cytochrome...
