Embodiment 1

[0053] Embodiment one: the modified atmosphere method of the present invention produces bean sprouts

[0054] The invention provides a method for the controlled atmosphere cultivation of mung bean sprouts, comprising the steps of:

[0055] (1) First, the raw beans are strictly screened to remove bad beans and germ-free beans.

[0056] (2) Blanch the beans, put the screened beans into hot water for 1 to 2 minutes, and stir.

[0057] (3) Soak the beans, soak the screened beans in warm water for 90 to 150 minutes.

[0058] (4) After soaking the beans, drain the water and spread the beans evenly in the incubator. The incubator is sterilized by high temperature or sprayed with 100PPM sodium hypochlorite.

[0059] (5) Move the incubator into the aseptic cultivation room to carry out the controlled atmosphere cultivation system of sprouts, the temperature is controlled at 22°C to 24°C, and water is sprayed periodically.

[0060] (6) On the 0th to 3rd day of cultivation, the volume...

Embodiment 2

[0063] Embodiment 2: Production of bean sprouts by controlled atmosphere at an outdoor temperature of 25°C to 35°C

[0064] First, strictly screen 50kg of mung beans as a raw material, put the screened beans into hot water at 80°C for 1 to 2 minutes, and stir at a stirring speed of 30 to 50 rpm. Soak in warm water at 35°C for 90 minutes, the ratio of beans to water is 1:4. After soaking the beans, drain the water and spread the beans evenly in the incubator. The incubator is sterilized by steam at a temperature above 100°C. Move the incubator into the aseptic cultivation room to carry out the controlled atmosphere cultivation system of sprouts. The temperature is controlled at 23°C, and the water temperature of the automatic spraying water every 4 hours is 20°C. On the 0th to 3rd days of cultivation, the volume fraction of circulating gas during cultivation is composed of 19.8% oxygen, 0.031% carbon dioxide, 78% nitrogen, and the rest are rare gases, and the gas circulation v...

Embodiment 3

[0065] Embodiment 3: Production of bean sprouts by controlled atmosphere method at an outdoor temperature of 25°C to 35°C

[0066] For 50kg of mung beans that have been strictly screened, put the screened beans into hot water at 90°C for 1 to 2 minutes, and stir at a stirring speed of 30 to 50 rpm, then soak in warm water at 33°C for 90 After soaking the beans, drain the water and spread the beans evenly in the incubator. The incubator is sterilized by spraying 100PPM sodium hypochlorite. Move the incubator into the aseptic cultivation room to carry out the controlled atmosphere cultivation system for sprouts. The temperature is controlled at 22°C, and the temperature of the automatic spraying water every 4 hours is 20°C. On the 0th to 3rd days of cultivation, the volume fraction of circulating gas during cultivation consists of 19.6% oxygen, 0.030% carbon dioxide, 76% nitrogen, and the rest are rare gases, and the gas circulation is 200 cubic meters per hour. On the 4th to 8...

Abstract

The invention discloses an air-regulation cultivation method for green bean sprouts and a device of the method. The method comprises the steps that green beans are heated in hot water of 95 DEG C, soaked in warm water for 90 minutes and subjected to high-temperature sterilization in a cultivation box, after sterilization, the green beans are placed in a sterile cultivation chamber for cultivation,from the starting time to the third day of cultivation, circulation gas in the cultivation period is composed of 19.8% of oxygen, 0.031% of carbon dioxide, 78% of nitrogen and the balance rare gas, from the fourth day to the eighth day, circulation gas in the cultivation period is composed of 18.5% of oxygen, 0.021% of carbon dioxide, 75% of nitrogen and the balance rare gas, and in the ninth day, cultivation is ended. According to the method, the problem is fundamentally solved that hormones, quantitative chemical medicine and the like are used for cultivating poisonous bean sprouts, the bean sprouts produced through the cultivation method are even in thickness and length of appearance, fresh and cool in taste, high in nutrient component content and low in poisonous chemical medicine residue content, timely quantitative control is conducted, the accuracy and stability of gas are guaranteed, the gas resources are also saved, and the environment of bean sprout production can be effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of food production, and in particular relates to a cultivation method of mung bean sprouts. Background technique [0002] In recent years, vicious food safety incidents have emerged in an endless stream in my country, and food safety has become the focus of attention of the country and the people. Bean sprouts is a nutritious and delicious food on the table of ordinary people in our country. However, some bean sprouts production enterprises and individuals add a large amount of plant growth hormone (such as: 6-benzyl adenine, 4 Sodium chlorophenoxyacetate, gibberellin, ethephon) and carbendazim, chlorothalonil, thiram, norfloxacin, penicillin and other drugs. Substances such as bleaching agent and sodium dithionite are used again in order to change the appearance of the bean sprouts that change color and turn yellow. At the same time, the bean sprouts added with plant growth hormone can grow within 3-5 days. For qu...
