Embodiment 1

[0032] 1) Squeeze

[0033] Take 1000Kg of fresh corn germs without rancidity and odor, remove impurities and send them to the drying room for drying. Dry them at 29-31°C until the water content is 8%, and then fry the dried corn germs with hot air. The frying temperature is 80°C. Feed the roasted corn germ into the SSYZ12 / 12 double-screw oil press, adopt the low-temperature oil extraction process, keep the outlet temperature of the corn germ meal at 110°C, and the oil output is about 250Kg, and the oil content of the corn germ meal is 8-10%.

[0034] 2) Prepare protein powder

[0035] First wash 750Kg of oily corn germ meal obtained in step 1) with water, drench off the cleaning solution, soak in 3 times of water for 0.5h, grind and refine with a mill, heat the refined slurry to 45°C, and stir while stirring Add NaOH to make the PH value to 8.0, soak at constant temperature for 1.5h. Remove the slag from the alkali-dissolved corn germ slurry with a pulp and slag separator, ...

Embodiment 2

[0037] 1) Squeeze

[0038] Take 1500Kg of fresh corn germs without rancidity and odor, remove impurities and send them to the drying room for drying, and dry them at 20-25°C until the water content is 7%, and then fry the dried corn germs with hot air. The roasting temperature is 70°C. Feed the roasted corn germ into the SSYZ12 / 12 double-screw oil press, adopt the low-temperature oil extraction process, keep the outlet temperature of the corn germ meal at 100°C, the oil output is about 375Kg, and the oil content of the corn germ meal is 9-11%.

[0039] 2) Prepare protein powder

[0040] First wash 1125Kg of oily corn germ meal obtained in step 1) with water, drench off the cleaning solution, soak in 4 times of water for 1.5 hours, grind and refine with a mill, heat the refined slurry to 40°C, and stir while stirring Add NaOH to bring the pH to 7.5, and soak for 2 hours at a constant temperature. Remove the slag from the alkali-dissolved corn germ slurry with a pulp and slag...

Abstract

The invention discloses oil-bearing maize embryo albumen powder containing 5-12 percent of oil grease. The preparation of the oil-bearing maize embryo albumen powder is as follows: low-modified oil-bearing corn germ meal is obtained with fresh maize embryo through low-temperature drying, roasting and squeezing; the oil-bearing maize embryo albumen powder is prepared by taking the obtained oil-bearing corn germ meal as raw material through an alkaline extraction and acid precipitation process. The albumen powder is rich in nutrition and good in quality and can be widely used in the food service industry. The invention also discloses a method for preparing the oil-bearing maize embryo albumen powder; which can greatly reduce the modification degree of the maize embryo protein in the processing and significantly increase the rate of comprehensive utilization and the added economic value of the maize embryo under the condition of low cost.

Description

technical field [0001] The invention belongs to the field of food processing, and relates to an oily corn germ protein powder and a manufacturing method thereof. Background technique [0002] Corn germ accounts for about 11.5% of the total corn kernel. Corn germ is rich in nutrients, including 34.5% fat, 18.8% protein, sugar, minerals, vitamins and other nutrients. [0003] Corn germ fat is a high-quality fatty acid with an unsaturated fatty acid content of more than 86%, rich in VE and phytosterols. Corn germ protein is a full-priced high-quality protein, of which albumin accounts for 30%, globulin accounts for 30%, and there are as many as 18 kinds of amino acids, which belong to full-valent protein. [0004] With the improvement of living standards, people's pursuit of high-quality protein nutrition is gradually heating up, and the market demand for protein nutrition foods such as corn and soybeans is very large. However, the main purpose of corn germ processing at pre...
