Method for extracting protein powder from corn germ meal

Abstract

The invention provides a method for extracting protein powder from corn germ meal. The method comprises the following steps that: related technical parameters are set by an arranged controller; a water suction pump I, a water suction pump II, a water suction pump III and a water suction pump IV run synchronously according to the related parameters set by the controller, so that soaking liquid in atank body I is suctioned into a tank body II by the water suction pump I, the soaking liquid in the tank body II is sucked into a tank body III by the water suction pump II, the soaking liquid in thetank body III is sucked into a tank body IV by the water suction pump III, the soaking liquid in the tank body IV is sucked into the tank body I by the water suction pump IV, and the soaking liquid flows circularly and regularly among all the tank bodies. A device for extracting the protein powder from the corn germ meal has the beneficial effects that the amount of the corn germ meal in once soaking is more, the soaking time is short, and the acidity of the soaking liquid is balanced, so that the protein extracted from the corn germ meal is full, the production efficiency is high and the raw-material utilization is high.

Description

technical field [0001] The invention relates to the field of extracting protein powder from corn germ meal, in particular to a method for extracting protein powder from corn germ meal. Background technique [0002] Corn germ is a by-product of corn starch and alcohol industry, accounting for about 10% to 15% of corn grains. It is very rich in nutrients, containing 15% to 23% of protein, more than 30% of fat, and rich in carbohydrates and amino acids , vitamins and minerals, have the functions of lowering blood cholesterol, preventing arteriosclerosis, and enhancing the vitality of brain cells. At the same time, the amino acid composition of corn germ protein is relatively balanced, and the protein efficacy ratio (PER) is 2.04-2.56, which is equivalent to beef (2.30), and has a good consistency with the human protein standard recommended by FAO / WHO. protein source. At present, corn germ in my country is only used as an oil resource to extract corn germ oil, and the remainin...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method for extracting protein powder from corn germ meal, which solves the problem that the above-mentioned existing device soaks corn germ meal with a small amount of soaking time, long soaking time, and low acidity of the soaking solution. Equilibrium makes corn germ meal extract protein insufficient, resulting in low production efficiency and low utilization rate of raw materials
