Embodiment 1

[0031] The production method of selenium-enriched bamboo shoots comprises the following steps:

[0032] a) add citric acid and sucrose reaction in sodium selenite aqueous solution, obtain selenium content and be 2000mg / kg selenium-enriched organic acid sucrose solution; The concentration of organic acid is 5g / kg; The concentration of sucrose is 20g / kg;

[0033] Described organic acid is citric acid; Described sucrose is white sugar;

[0034] b) Dilute the above-mentioned selenium-enriched organic acid solution with pure water, and control the selenium concentration to 20 mg / kg to obtain selenium-enriched organic acid sucrose injection;

[0035] c) choose the bamboo shoots grown from the bamboo whip of the female bamboo that has grown vigorously in 2-4 years. When the shoot tip is outcropped and the shoot body is still in the soil, clean the soil on the surface of the shoot body along the shoot body to 10-30cm underground. Use a syringe to inject 20ml to 40ml of selenium-enric...

Abstract

The invention discloses a production method of selenium-enriched bamboo shoots. The production method comprises adding organic acid and sucrose into a sodium selenite aqueous solution for reaction to obtain a selenium-enriched organic acid sucrose solution; adding the pure water into the selenium-enriched organic acid sucrose solution for dilution, controlling the selenium concentration into 20 to 40 mg every kg and obtaining a selenium-enriched organic acid sucrose injection; injecting 20 to 40 ml of selenium-enriched organic acid sucrose injection into a bamboo shoot body through a syringe in an inclined mode and sealing an injection hole through the beewax; harvesting when bamboo shoots are 20 to 30 cm higher than the ground after 3 to 7 days of injection to obtain the selenium-enriched bamboo shoots. According to the production method of the selenium-enriched bamboo shoots, the obtained selenium-enriched bamboo shoots are high in nutritional value, slightly sweet and free of bitter, nutrients such as the rich protein and the amino acid, particularly the trace element selenium, are contained in the selenium-enriched bamboo shoots, the good antioxidant effect such as the cosmetic, anti-cancer and anti-aging effect is achieved, and the selenium-enriched bamboo shoots can be utilized as antioxidants or health food development raw materials.

Description

technical field [0001] The invention belongs to the technical field of functional foods, and in particular relates to a production method of selenium-enriched bamboo shoots. Background technique [0002] Selenium is a chemical element discovered by Swedish chemist Berzelius in 1817. At first people regarded selenium as a poisonous element. In 1973, the World Health Organization announced that selenium is an essential trace element for the human body; in 1974, the U.S. Food and Health Administration stipulated that in order to ensure that people can obtain enough selenium, selenium must be added to the feed of edible animals; Listed as one of the daily dietary nutrients. On January 24, 2011, the Ministry of Health issued the No. 3 Announcement, saying: According to the provisions of the "Food Safety Law" and the "Measures for the Administration of National Food Safety Standards", after review and approval by the National Food Safety Standard Review Committee, it was decided...
