Selenium-enriched mung bean sprouts and production method thereof

Abstract

The invention discloses selenium-enriched mung bean sprouts and a production method thereof, and belongs to the technical field of production of selenium-enriched agricultural products. The method includes the specific steps: inoculating capsule rhodobacter AYGHJ-16 in a culture medium to prepare selenium-enriched inoculant, diluting the selenium-enriched inoculant with water to selenium-enriched inoculant diluent in the volume 60-80 times of that of the selenium-enriched inoculant, placing mung bean seeds in the selenium-enriched inoculant diluent in 80 times volume for seed soaking and accelerating germination for 24-48 hours, then sprouting and growing at the room temperature of 20-28 DEG C, spraying with the selenium-enriched inoculant diluent in 60 times volume for one time every four hours in a sprouting process until sprouts grow to 5-8 centimeters after 4-5 days of sprouting and grouping, and taking out the sprouts prior to washing clean with running water so that the selenium-enriched mung bean sprouts are obtained. The selenium-enriched mung bean sprouts produced by the method are 1-1.2mg / L in selenium content, free of inorganic selenate or selenite and capable of meeting requirements on long-term security selenium supplement of people.

Description

technical field [0001] The invention belongs to the technical field of production of selenium-enriched agricultural products, in particular to a selenium-enriched mung bean sprouts 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 and aging p...

Problems solved by technology

However, in the past, the technology of producing selenium-enriched mung bean sprouts was to add sodium selenate and sodium selenite in the soaking and spraying water, and 30-40% inorganic selenic acid inevitably remained in the total selenium content of the selenium-enriched mung bean sprouts produced. Salt or selenite, which has certain toxic and side effects, is rarely used now
