Selenium-rich soybean sprouts and production method thereof

Abstract

The invention discloses selenium-rich soybean sprouts and a production method thereof and belongs to the technical field of production of selenium-rich agricultural products. The production method comprises the following particle steps of: inoculating rhodopseudomonas bacteria AYGHJ-16 in a culture medium to prepare a selenium-rich bacterial agent; diluting the selenium-rich bacterial agent into selenium-rich bacterial agent diluent of which the volume is 20 to 50 times the volume of the selenium-rich bacterial agent with water; after placing soybean seeds into the 50-times selenium-rich bacterial agent to carry out seed soaking for 24 to 48 hours, enabling the soybean seeds to sprout and grow at a room temperature of 20 to 25 DEG C; in the sprouting process, spraying the soybeans with the 20-times selenium-rich bacterial agent at time intervals of 4 hours, so that after sprouting and growing for 5 to 6 days, bud seedlings grow to 8 to 10cm; and after taking out the bud seedlings, flushing the bud seedlings clean with tap water so as to obtain the selenium-rich soybean sprouts. The selenium-rich soybean sprouts produced by the method has the selenium content of 1 to 1.5mg / L, does not contain inorganic selenate or selenite and can meet the requirement of people for long-term safety 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 soybean sprout 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 an...

Problems solved by technology

However, in the past, the technology of producing selenium-enriched soybean 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 soybean sprouts produced. Salt or selenite, which has certain toxic and side effects, is rarely used now
