Problems solved by technology

[0004] At present, selenium-enriched spirulina products at home and abroad are still mainly at the level of whole algae powder. As a health food, it needs to be taken in large doses to be effective. However, as a plant cell, selenium-enriched spirulina has a thick cell wall and is not easy to be digested and absorbed. Take more than 10-30 grams per day. Even if the cell wall is broken, it will waste a lot. In addition, the algae itself is alkaline (pH8.0-10). Taking a large amount will neutralize gastric acid and affect the digestive function of the stomach. Selenium spirulina has an unpleasant fishy smell and very bad taste

Embodiment 1

[0021] Embodiment 1, A kind of crushing method of spirulina (enriched in selenium)

[0022] Weigh 500g of fresh spirulina (enriched in selenium), suspend it in 1000ml of pure water, and extract it by ultrasonic crushing in an overflow cycle at 0°C. The ultrasonic power is 24000W, the frequency is 15KHZ; the ultrasonic working time is 20s, the intermittent time is 20s; the ultrasonic crushing time is 10 minutes, every working 5 minutes, intermittent 5 minutes. After the ultrasonic crushing was completed, samples were taken, and the crushing of the Spirulina was observed under a 400-fold microscope. The result showed that the Spirulina (selenium-enriched) cells were completely broken.

Embodiment 2

[0023] Embodiment 2, A kind of crushing method of spirulina (enriched in selenium)

[0024] Weigh 500g of fresh spirulina (enriched in selenium), suspend in 1000ml of pure water, and extract by ultrasonic crushing in overflow cycle at 10°C. Ultrasonic power is 4600W, frequency is 33KHZ; ultrasonic working time is 10s, intermittent time is 10s; ultrasonic crushing time is 60 minutes, every working 5 minutes, intermittent 5 minutes. After the ultrasonic crushing was completed, samples were taken, and the crushing of the Spirulina was observed under a 400-fold microscope. The result showed that the Spirulina (selenium-enriched) cells were completely broken.

Embodiment 3

[0025] Embodiment 3, A kind of crushing method of spirulina (enriched in selenium)

[0026] Weigh 500g of fresh spirulina (enriched in selenium), suspend in 1000ml of pure water, and extract by ultrasonic crushing in overflow cycle at 40°C. Ultrasonic power is 600W, frequency is 80KHZ; ultrasonic working time is 5s, intermittent time is 20s; ultrasonic crushing time is 120 minutes, every working 5 minutes, intermittent 5 minutes. After the ultrasonic crushing was completed, samples were taken, and the crushing of the Spirulina was observed under a 400-fold microscope. The result showed that the Spirulina (selenium-enriched) cells were completely broken.

Abstract

The invention belongs to the technical field of biochemical separation and purification, and relates to a production process and a preparation method of spirulina platensis nutritious protein powder. Spirulina platensis rich in selenium is used as a raw material, is subjected to disruption extraction by overflowing circulating ultrasonic waves and is filtered by filter cloth, filtrate is centrifuged at 6000-18000rpm for 10-60min at 0-40 DEG C, liquid supernatant is intercepted by an ultrafiltration membrane separation system to obtain required active protein solution, and the required active protein solution is subjected to microwave vacuum drying to obtain the selenium-enrichment spirulina platensis nutritious protein powder. The process and the preparation method are simple and easy to operate, have low energy consumption and can be used for industrial production, and the natural activity, the color, aroma and taste and the nutritional ingredients of the prepared products are reserved well.

Description

technical field [0001] The invention relates to a production process and preparation method of spirulina nutritional protein powder, belongs to the technical field of biochemical separation and purification, and can be used in the fields of food, health food and cosmetics. Background technique [0002] Spirulina, also known as blue-green algae, has lived on the earth for 3.5 billion years and is one of the oldest living organisms on the earth. Spirulina is extremely nutritious, with protein content as high as 60-70%, three times that of beef, four times that of pork liver, six times that of eggs, and 10 times that of rice. The protein contained in spirulina is composed of 18 kinds of amino acids, of which 8 It is necessary for the human body and cannot be synthesized by itself. Selenium (Se) is an essential trace element for the human body, known by scientists as the "king of cancer prevention" among trace elements in the human body. The Chinese Nutrition Society also lists...
