Description

Feed additive and application thereof Technical Field The invention relates to the technical field of feed additives, in particular to a feed additive and application thereof. Background The problem of handling threonine mother liquor has been a focus of attention. There are various prior art techniques for treating threonine mother liquor. The common ion exchange column method is to separate the impurities in the threonine mother liquor from threonine by using the ion exchange column, so that the threonine recovery rate is high, and the decolorization and desugaring effects are achieved. However, this method is expensive in equipment, high in running cost, and suitable for small-scale production. The membrane separation technology separates pigment, sugar and threonine in threonine mother liquor by utilizing the separation performance of the membrane, and has the advantages of convenient operation, simple equipment, energy conservation, environmental protection and the like. However, membrane materials are prone to contamination and breakage, require periodic backwashing, cleaning and inspection, and are costly to operate at a later stage. The multi-effect evaporation spray drying technology adopts the multi-effect evaporation and spray drying method to treat threonine mother liquor into solid organic compound fertilizer, and the wastewater is discharged after reaching standards, thus being a feasible treatment method. However, this method is relatively inefficient for mass production. The chromatographic separation technology is used for recovering threonine mother liquor, so that pigments, sugar and threonine can be effectively separated, the recovery rate of threonine is improved, and the production loss is reduced. However, this method is not widely used for production and is unstable in operation. Electrodialysis desalination technology provides a feasible method for treating threonine mother liquor by changing electrodialysis operation conditions, such as desalination solution flow rate, electrodialysis current density and the like, and exploring the optimal conditions of electrodialysis desalination. The hydrolysis technology for reducing sugar concentration includes regulating pH value with sulfuric acid, heating to hydrolyze to convert polysaccharide in threonine mother liquid into monosaccharide, raising sugar utilization rate, reducing residual sugar content, lowering production cost and energy consumption, reducing pollutant discharge and protecting environment. The technology has certain application and research on the aspect of treating the feed additive in the threonine mother liquor, and aims to improve the product quality, reduce the cost and reduce the environmental pollution. The invention adopts a method for re-fermenting and utilizing threonine mother liquor, and a plurality of coloring agents such as lemon yellow, sunset yellow, allure red, carmine, indigo, titanium dioxide, caramel color (ammonium sulfite method), erythrosin and the like exist in the current feed additive catalog. And (3) after various colorants are proportionally mixed in water, the mixture is sprayed into other raw material mixtures and uniformly mixed, so that a feed finished product with a fresh yellow sensory color can be formed. However, the finished feed product produced by such a method is liable to change in color under various temperatures and moderate conditions, and its coloring effect is unstable. According to the invention, the color of the amino acid liquid raw material is adjusted, so that the color optimization of the protein raw material product is realized, and the cost performance of the product is increased. And further through the preparation of the feed additive, the adsorption of deoxynivalenol and zearalenone is realized, and the biological fermentation protein raw material has better palatability and safety.
