Problems solved by technology

But in the past, the technology of producing selenium-enriched Chinese toon buds all adopts to add sodium selenate and sodium selenite in soaking and spraying water, and 30-40% inorganic selenic acid remains unavoidably in the total selenium content of selenium-enriched Chinese toon buds produced Salt or selenite, which has certain toxic and side effects, is rarely used now

Embodiment Construction

[0014] Below in conjunction with embodiment the invention is described in further detail.

[0015] 1) Preparation of selenium-enriched bacterial agent

[0016] Preparation method of fermentation medium: take 150mg sodium selenite, 40g glucose, 7.5g peptone, 9g urea, 5g yeast extract, 0.4g NaHCO 3 , lg NH 4 Cl, 0.2g K 2 HPO 4 、2.O CH 3 COONa, 0.2g MgSO 4 ·7H 2 O, 2.0g NaCl and 10ml trace element solution were dissolved in water and the volume was adjusted to 1000ml; the fermentation medium was sterilized at 115°C for 20min. The fermentation medium can be of pH 6.7-7.2.

[0017] The preparation method of trace element solution: take 0.5g H 3 BO 3 , 400mg MnSO 4 , 60mg ZnSO 4 ·7H 2 O, 180mg NaMoO 4 2H 2 O and lOmg Ca(NO 3 ) 2 2H 2 O, dissolved in water and adjusted to 250ml.

[0018] Add 160L of fermentation medium to the fermenter, and then inoculate Rhodobacter capsulata AYGHJ-16 (CCTCC NO: M 2011377); fermentation conditions: temperature control at 30°C, carb...

Abstract

The invention discloses selenium-rich Chinese toon sprouts and a production method thereof and belongs to the technical field of selenium-rich agriculture product production. The production method comprises the following specific steps: inoculating capsule rhodobacter AYGHJ-16 in a culture medium to prepare a selenium-rich microbial inoculum, diluting the selenium-rich microbial inoculum with water into 20-50 times volume of selenium-rich microbial inoculum diluent, putting Chinese toon seeds into the 50 times selenium-rich microbial inoculum diluent to be soaked and germinated for 24-48 hours, sprouting and growing at the room temperature of 20-25 DEG C, spraying once by using the 20 times selenium-rich microbial inoculum diluent every other four hours in the sprouting process, after sprouting and growing for 5-6 days, sprouts grow to 8-10 cm, taking out the sprouts and washing the sprouts with running water to obtain the selenium-rich yeast Chinese toon sprouts. The selenium-rich Chinese toon sprouts produced by the method contain 1-1.5mg / L of selenium, do not contain inorganic selenate or selenite and can meet the requirement of people for long-term safe selenium supplement.

Description

technical field [0001] The invention belongs to the technical field of production of selenium-enriched agricultural products, and in particular relates to a selenium-enriched Chinese toon bud and a production method thereof. Background technique [0002] Selenium is an essential micronutrient for animals and humans. The International Selenium Society recommends a daily intake of 60-400 μg, and the Chinese Nutrition Society recommends a daily intake of 50-200 μg. According to my country's nutritional survey, the daily intake of selenium for adults is only 26-32 μg. Therefore, selenium malnutrition is a common problem in our population. my country's selenium-deficient soil accounts for 72% of the country's land area, and the selenium-deficient population reaches more than 100 million. Many endemic high-incidence diseases in my country, such as Keshan disease, Kaschin-Beck disease, cancer, cardiovascular and cerebrovascular diseases, diabetes, infertility, weakened immunity ...
