Problems solved by technology

[0005] In order to overcome the existing spirulina powder adopting ethylene oxide and gamma ray sterilization method requires high equipment and there are factors affecting the product composition, the ethanol steam sterilization method is not sufficient for sterilization, and the room temperature ethanol sterilization method takes a long time and has low efficiency. Insufficient, the present invention proposes a kind of rapid sterilization method of spirulina powder with short sterilization time, low equipment investment, high safety and good sterilization effect

Embodiment 1

[0019] A rapid sterilization method for spirulina powder, which goes through the following process steps:

[0020] (1) Chemical sterilization: Put the spirulina powder into a container, add 70% medicinal ethanol to the container, stir evenly to make the spirulina powder fully moistened, seal and infiltrate and sterilize for 10 minutes;

[0021] (2) Intermittent sterilization: The spirulina powder obtained in step (1) after being sealed and infiltrated is sterilized and dried for 10 minutes with circulating steam at a temperature of 100°C to kill the vegetative cells in the spirulina powder;

[0022] Cultivate the sterilized and dried spirulina powder at room temperature or in an incubator to make the unkilled spores germinate and grow into vegetative cells, and then use circulating steam at a temperature of 100°C for secondary sterilization and drying for 10 minutes. Kill newly grown vegetative cells.

Embodiment 2

[0024] A rapid sterilization method for spirulina powder, which goes through the following process steps:

[0025] (1) Chemical sterilization: Put the spirulina powder in a container, add 75% medicinal ethanol to the container, stir evenly to make the spirulina powder fully moistened, seal and infiltrate and sterilize for 20 minutes;

[0026] (2) Intermittent sterilization: the spirulina powder obtained in step (1) after being sealed and infiltrated is sterilized and dried for 20 minutes with circulating steam at a temperature of 105°C to kill the vegetative cells in the spirulina powder;

[0027] Cultivate the sterilized and dried spirulina powder at room temperature or in an incubator to make the unkilled spores germinate and grow into vegetative cells, and then use circulating steam at 105°C for secondary sterilization and drying for 20 minutes. Kill newly grown vegetative cells.

[0028] (3) Repeated sterilization: the secondary sterilized and dried spirulina powder obtained in st...

Embodiment 3

[0030] A rapid sterilization method for spirulina powder, which goes through the following process steps:

[0031] (1) Chemical sterilization: Put spirulina powder into a container, add medicinal ethanol with a concentration of 85% to the container, stir evenly to make the spirulina powder fully moistened, seal and infiltrate and sterilize for 30 minutes;

[0032] (2) Intermittent sterilization: the spirulina powder obtained in step (1) after being sealed and infiltrated is sterilized and dried for 30 minutes with circulating steam at a temperature of 110°C to kill the vegetative cells in the spirulina powder;

[0033] Cultivate the sterilized and dried spirulina powder at room temperature or in an incubator to make the unkilled spores germinate and grow into vegetative cells, and then use circulating steam at 110°C for secondary sterilization and drying for 30 minutes. Kill newly grown vegetative cells.

[0034] (3) Repeated sterilization: the secondary sterilized and dried spirulina...

Abstract

The invention discloses a quick sterilization of spirulina powder. The method mainly solves the problems of high equipment requirement and unsatisfactory sterilization effect in existing spirulina powder sterilization. The invention adopts the method combining ethanol infiltration chemical sterilization with circulating steam intermittent sterilization. Specifically, the method includes: adding spirulina powder into medicinal ethanol to conduct infiltration, and performing sealing sterilization; then employing circulating steam to conduct sterilization and drying to kill nutritional somatic cells in spirulina powder; and culturing the sterilized and dried spirulina powder at room temperature or in an incubator to let unkilled spores germinate and grow into nutritional somatic cells, then employing circulating steam to conduct secondary sterilization and drying. The sterilization method provided by the invention maintains the nutrition of spirulina itself, and has the advantages of short sterilization time, low equipment investment, high safety and good sterilizing effect.

Description

technical field [0001] The invention relates to the preparation of edible seaweed, in particular to a rapid sterilization method of spirulina powder. Background technique [0002] Spirulina belongs to the lower plants of Cyanophyta Oscillatoriaceae, rich in protein, β-carotene and vitamins B1, B2, B5, B6, B11, B12, C and E, and contains a variety of essential trace elements, calcium, Magnesium, sodium, potassium, phosphorus, iodine, selenium, iron, copper, zinc, etc.; the γ-linolenic acid contained in it can promote calcium absorption, improve immunity, prevent metabolic disorders and prevent aging; The function of radiation, and indirectly inhibit the proliferation of cancer cells by enhancing the body's immunity. Spirulina polysaccharide can increase the activity of SOD in plasma, reduce the generation of lipid peroxides, and have anti-aging effects. It is precisely because of the various health functions of spirulina that it is widely used in dietary supplements. [000...
