Embodiment 1

[0032] Embodiment 1: The influence of different temperature treatment on bean sprouts anthracnose spore germination

[0033] The effect of different temperature treatments on the spore germination of bean sprout anthracnose was determined by spore liquid coating method. Put the purified mycelial mass of bean sprout anthracnose into sterile potato liquid medium (PD), place it in a shaker at a constant temperature of 150rpm at 25°C for 3 days, and then dilute it with sterile water to a concentration of 10% of the pathogenic spore suspension. 7 A / L spare. Use a pipette gun to draw 200 μL of spore suspension into a PCR tube, and then put it into a gradient PCR instrument for temperature treatment. The treatment temperature is 45-60°C, and the treatment time is 2min, 5min, 10min, 15min, and 20min. Treat 3 repetitions. Draw 100 μL of temperature-treated spore suspension onto the poured potato agar medium plate under aseptic operation, spread it evenly with a spreader, place it in ...

[0039] Embodiment 2: the impact of different temperature treatments on bean sprouts bacterial rot

[0040] With the test method of Example 1, the isolated bean sprout rot disease pathogenic bacteria were single-colonized into the LB culture medium, and the test was carried out after culturing at 28° C. for 24 hours with constant temperature shaking (150 rpm). The treatment temperature was 45-60°C, the treatment time was 6h, 12h, 18h, 24h and 30h, and each treatment was repeated 3 times.

[0041] The test results are shown in Table 2. The temperature treatment was 30-60°C, with a total of 16 temperature gradients. The plate was placed in a constant temperature incubator at 28°C for 24 hours and then the growth of colonies on the surface was recorded. The temperature test was repeated three times.

Embodiment 3

[0046] Embodiment 3: the influence of different disinfection methods on mung bean germination

[0047] Mung beans were sterilized by dry heat at different temperatures, and the effects of different treatments on the detection rate and germination rate of mung bean pathogens were determined. Select plump and mature mung bean seeds (germination rate ≥ 98%) for experimental treatment, soak mung beans in clean water for 30 minutes to remove impurities, then screen the expanded mung bean seeds, select plump mung bean seeds and use a dry heat disinfection box for disinfection For treatment, the treatment temperature is 50-65°C, a gradient of 5°C, and the treatment time is 18h and 24h. Put the dry heat sterilized mung bean seeds in a dry heat disinfection box at room temperature for 24 hours to allow them to regain moisture naturally, so as to prevent the mung beans from being broken during subsequent processing; soak the mung beans that have naturally regained moisture in ozone nano...

Abstract

The present application discloses a disinfection method of raw material seeds in bean sprout production and an application of the disinfection method. The method comprises the following steps: 1) exposing raw material seeds of bean sprouts to a dry heat treatment atmosphere, wherein the dry heat treatment atmosphere has a temperature of at least 50 DEG C, and exposing the raw material seeds of thebean sprouts until time of the dry heat treatment atmosphere is at least 18 h; and 2) soaking raw material seeds of the bean sprouts after the dry heat treatment to a disinfectant containing ozone nano bubble water for 4-6 h. The disinfection method can significantly reduce occurrence of bean sprout diseases by inhibiting pathogenic microorganisms of fungal anthracnose and bacterial rot disease carried by the raw material seeds of the bean sprouts, does not affect a germination rate of the bean sprouts, is high in safety, free of pesticide residues and simple in processes, and ensures consumption safety of the bean sprouts.

Description

technical field [0001] The application belongs to the technical field of bean sprouts production, and in particular relates to a method for disinfecting raw material seeds in bean sprouts production and its application. Background technique [0002] Bean sprouts is a traditional vegetable in my country, which is generally cultivated by leguminous plant seeds such as soybeans, mung beans, and pea seeds under suitable moisture, temperature, air and dark environmental conditions. radicle or unexpanded cotyledons) for feeding. The traditional bean sprouts production process uses technical means such as temperature control and water spraying to produce products with thick hypocotyls, crisp and tender, and short radicles. In long-term consumption, with the improvement of living standards, people have higher requirements for the palatability of bean sprouts, and bean sprouts that are thick, white and tender, sweet and crisp, and have no radicle are more and more favored by consumer...
