Embodiment 1

[0033] Dry the mung bean seeds at 40°C to a water content of 3%; put the seeds into an electric constant temperature blast drying oven for high-temperature sterilization, first treat at 70°C for 0.1h, then heat up to 80°C for 1h, and then cool to room temperature; Put the high-temperature sterilized seeds into a sealed bag, vacuumize them, and store them at 4°C.

Embodiment 2

[0035] Dry the mung bean seeds at 40°C to a water content of 3%, immerse in a vegetable oil coating agent, soak at room temperature for 3 minutes, take them out and dry them in the air, put the seeds into an electric constant temperature blast drying oven for high-temperature sterilization, and treat them at 70°C for 0.1 h, then heat up to 80°C for 1h, then cool to room temperature; put the sterilized seeds into a sealed bag, vacuumize, and store at 4°C.

[0036] Wherein, the vegetable oil coating agent includes the following raw materials by weight: 60 g of vegetable oil, 20 g of chitosan, 3 g of modified titanium dioxide nanorods, 2 g of phytoncide, and 1230 g of 1% acetic acid solution by volume fraction. Its preparation method is as follows:

[0037] Weigh the dried titanium dioxide nanorods, add them into isopropanol at a ratio of 1g / 10mL, and disperse with 400W ultrasonic waves for 15min to obtain a titanium dioxide nanorods solution;

[0038] Then weigh 6g of titanate ...

Abstract

The invention discloses a high-temperature sterilization method for mung bean seeds, and relates to the technical field of treatment of crop seeds. The high-temperature sterilization method comprisesthe following steps: drying the mung bean seeds at the temperature of 40 DEG C until the water content reaches 3-5%, placing the seeds into an electric heating constant-temperature air blast drying oven, carrying out high-temperature sterilization, treating the seeds at the temperature of 70 DEG C for 0.1-0.2 hour, then heating the seeds to the temperature of 80 DEG C to be treated for 1-1.5 hours, cooling the seeds to room temperature, filling a sealed bag with the seeds, carrying out vacuumizing, and storing the seeds at the temperature of 4 DEG C. According to the method disclosed by the invention, a film layer is formed on the surface of each of the mung bean seeds, so that the mung bean seeds are uniformly heated in the sterilization process; and moreover, plant bacteriocins are addedinto the film layers, pathogenic bacteria can be thoroughly killed in cooperation with high temperature, and the pathogenic bacteria carried on the seeds can be fully killed. Meanwhile, by the film layers, the evaporation rate of seed moisture can be reduced, and the germination rate of the seeds is guaranteed.

Description

technical field [0001] The invention relates to the technical field of crop seed treatment, in particular to a high-temperature sterilization method for mung bean seeds. Background technique [0002] Mung bean, also known as green bean, is an annual herbaceous plant belonging to the legume family Vigna, and is planted in various places in the north and south of my country. Mung beans are rich in nutrients. According to measurements, every 100 grams of mung beans contains 58.8 grams of carbohydrates, 23.8 grams of protein, 0.5 grams of fat, 0.36 grams of phosphorus, 80 mg of calcium, and carotene, vitamins (VB1, VB2, VE), niacin, etc. A variety of nutrients. Mung beans are full of treasures. The seeds are not only edible, but also can extract starch (making mung bean paste, mung bean cake, mung bean powder skin, vermicelli, etc.), add water to shading germination (cultivate sprouts, and make vegetables); Boil soup for drinking, which has the effects of clearing heat, preven...
