Problems solved by technology

[0002] Corn gluten meal (corn gluten meal) is a by-product of wet production of corn starch, containing about 60% protein, of which zein accounts for about 65% of protein, followed by pigments, oils, etc. Most of our country produces starch Enterprises sell corn yellow powder as cheap feed, and some companies do not make any use of corn yellow powder when producing starch, and discharge it with waste liquid, resulting in a waste of resources

Embodiment 1

[0018] A kind of technique of separating yellow pigment from corn yellow powder, it comprises the steps:

[0019] 1) Crush, soak, stir and centrifuge: take corn yellow powder, crush, soak in water five times its weight, stir at 300rpm for 5min, then let stand for 50min, remove the upper layer of grease, and then centrifuge to collect the sediment and upper liquid;

[0020] 2) Preparation of fermentation medium: 9% glucose, 70% upper liquid, 0.2% magnesium sulfate heptahydrate, 0.2% potassium hydrogen phosphate, 0.001% ferrous sulfate heptahydrate, VB 1 0.00001%, the rest is water, stir evenly, adjust pH to 7.0-7.2;

[0021] 3) Extrusion: Add the precipitate obtained in step 1) to an extruder for extrusion processing to obtain material A. The extrusion parameters are: the diameter of the die hole is 2mm, the temperature of the extruded material is 120°C, and the water content is 18wt %;

[0022] 4) Ultrasound, extraction and drying: mix according to the ratio of material A: ...

Abstract

The invention belongs to the technical field of deep processing of corn gluten meal, and discloses a technology for separating yellow pigment from corn gluten meal. The technology comprises the following steps: 1) grinding, soaking, stirring and centrifuging; 2) preparing a fermentation culture medium; 3) extruding; 4) ultrasonically treating, extracting and drying; and 5) performing acid-base treatment and centrifugal drying. The invention realizes the co-production technology for comprehensive treatment of the corn gluten meal and the fermentation culture medium, the yield and purity of the produced yellow pigment, alcohol-soluble protein and glutelin are high, and a new idea is provided for the comprehensive utilization of the corn gluten meal.

Description

technical field [0001] The invention belongs to the technical field of corn yellow powder deep processing, relates to a comprehensive treatment process of corn yellow powder, in particular to a process for separating yellow pigment from corn yellow powder. Background technique [0002] Corn gluten meal (corn gluten meal) is a by-product of wet production of corn starch, containing about 60% protein, of which zein accounts for about 65% of protein, followed by pigments, oils, etc. Most of our country produces starch Enterprises sell corn yellow powder as cheap feed, and some companies do not make any use of corn yellow powder when producing starch, and discharge it with waste liquid, resulting in a waste of resources. [0003] Zeaxanthin belongs to carotenoids and is a mixture of several natural pigments, mainly zeaxanthin, cryptoxanthin and lutein. Studies have shown that zeaxanthin has many physiological functions, and it can effectively protect eyesight, fight cancer, and ...
