Embodiment 1

[0030] A preparation method of spirulina protein powder, comprising the following steps:

[0031] A, 125kg of spirulina is pulverized by a pulverizer to obtain spirulina powder with a mesh number of 1200-1500, wherein the pulverizer speed is 5000-1000r / min, and the pulverization time is 10-15min;

[0032] B. Add 1000kg of water to the pulverized spirulina powder and stir evenly, the stirring temperature is controlled at 20°C, and the stirring time is 8h. The spirulina powder fluid after the uniform stirring is placed in a high-pressure homogenizer for homogenization. Make the spirulina powder swell, burst, and release the broken spirulina protein, wherein the temperature of the spirulina powder treated by the high-pressure homogenizer is controlled below 12°C to prevent the denaturation of the protein in the spirulina powder due to excessive temperature;

[0033] C. Add 3% calcium chloride to the broken spirulina protein, and automatically squeeze out the protein liquid in the...

Embodiment 2

[0038] The difference between Example 2 and Example 1 is that in step B, the stirring temperature is 15° C., and the stirring time is 10 h.

[0039] The purity of the spirulina protein powder prepared in Example 1 is 70%, and the concentration is 12g / L; the purity of the spirulina protein powder prepared in Example 2 is 75%, and the concentration is 13g / L, prepared by the preparation method of the spirulina protein powder of the present invention The purity and concentration of the spirulina protein powder have been greatly improved, and the entire production and purification process adopts a physical method based on an air flotation separation and purification device. The air flotation separation and purification device combines the extraction of the spirulina protein powder with the The separation of light impurities is combined into one, which simplifies the process flow and improves the use efficiency and separation quality of products. At the same time, the spirulina prot...

Abstract

The invention belongs to the technical field of biochemical separation and purification, and relates to a preparation method of spirulina protein powder. The method comprises the following steps: firstly crushing spirulina powder, uniformly mixing the spirulina powder with 8 to 10 times of water, and then laying spirulina powder fluid into a high pressure homogenizer to perform homogenizing treatment on the fluid, so as to release spirulina protein subjected to wall breaking, pressing the spirulina protein subjected to wall breaking to form protein fluid, unfreezing and extracting the proteinfluid, laying the protein fluid to an air flotation separation and purification device to perform purity extraction, and finally drying the purified protein fluid, so as to obtain the spirulina protein powder. The method solves the problems of long process route, long extraction period, high energy consumption and low production efficiency of a preparation method of spirulina protein powder in theexisting prior.

Description

technical field [0001] The invention belongs to the technical field of biochemical separation and purification, and relates to a method for preparing spirulina protein powder, in particular to a method for preparing spirulina protein powder purified by an air flotation separation and purification device. Background technique [0002] Spirulina is a photoautotrophic organism, and its algae cells contain photosynthetic lamina (thylakoid), vitamins, crude protein, crude fat, carbohydrates, carotene, etc. Spirulina is rich in protein, up to 60-70%. Spirulina is rich in β-carotene, which is 15 times that of carrots and 40-60 times that of spinach. Spirulina is rich in vitamins B1, B2, B5, B6, B11, B12, C, E. There are many kinds of B vitamins, and each has a special physiological function, and the lack of any one of them may lead to disease. Spirulina contains a variety of essential trace elements, such as calcium, magnesium, sodium, potassium, phosphorus, iodine, selenium, ir...
