Problems solved by technology

[0010] In view of the currently widely used corn yellow pigment solvent extraction method, the requirements for reagents and extraction conditions are high and the effect is poor. At the same time, the general high-tech auxiliary extraction method has the problems of long processing time, complicated operation, expensive equipment and high cost. , and the extraction efficiency and yield are low, it is difficult to apply to industrial production, and the extraction efficiency and yield are low, and the application range is narrow. The present invention proposes a method for using laser-assisted extraction of zeaxanthin food additives, thereby It effectively guarantees the extraction efficiency and is suitable for large-scale promotion

Abstract

The invention provides a method for extracting a corn yellow pigment food additive through laser assistance. The method comprises the following steps of compounding corn protein powder tiny powder into suspension liquid, performing enzymolysis with cellulase and neutral protease, adding precipitate obtained through filtering enzymatic hydrolysate into ethanol, assisting extraction with laser illumination, after an extraction solution is filtered, taking supernatant, removing protein through chitosan flocculation, performing decompressed concentration, and performing vacuum freeze drying so asto obtain the corn yellow pigment food additive. According to the method, enzymes in corn can be activated through laser illumination, cell walls are thoroughly destroyed, pigment is released to the maximum extent, the extraction efficiency is high, the yield is high, the safety is good, and the corn yellow pigment food additive can be used as a coloring agent and an additive of various foods. Besides, the cost of equipment and raw materials is low, and the method is suitable for industrialized production.

Description

technical field [0001] The invention relates to the field of food, in particular to the extraction of zeaxanthin, in particular to a method for extracting zeaxanthin food additives with laser assistance. Background technique [0002] Corn is a one-year herbaceous plant belonging to the family Poaceae Maize, which has the characteristics of wide planting area and large yield. In recent years, the application of corn has become more and more extensive. In terms of nutrition, the energy utilization rate of corn is higher. In addition to high content of fat-soluble vitamin E and lutein, corn seeds also have glutathione, which has the functions of delaying aging and enhancing immunity. In terms of medicine, corn has the effects of lowering blood pressure, lowering blood sugar, and preventing arteriosclerosis. Therefore, the research and development of corn has become a research hotspot at home and abroad. [0003] Zeaxanthin is a mixture of oxygen-containing derivatives of sev...
