Embodiment 1

[0022] (1) During the best harvesting period of wheat seedlings, manually harvest wheat seedlings, remove old leaves and yellow leaves through sorting, and obtain 2000 kg of fresh and tender wheat seedlings, which takes 30 minutes.

[0023] (2) Evenly put the fresh and tender wheat seedlings into the automatic turning cleaning equipment, rinse and spray to remove surface impurities, and the fresh wheat seedlings after cleaning enter the squirrel cage crusher through the conveyor belt for physical wall breaking and squeezing. The crusher speed is 1440r / min. The blade is sawtooth-shaped and has double-sided blades; the mixed liquid obtained after crushing is pressed through a 5T / H belt-type juicer with automatic deviation correction and automatic belt washing functions, and it takes 50 minutes to obtain pasty wort.

[0024] (3) The pasty wort is filtered through a resonance filter to obtain the clear liquid, and the clear liquid is continuously concentrated by a single-effect vac...

Abstract

The invention discloses a process for extracting active SOD (Superoxide Dismutase) from wheat seedlings. The process comprises the following steps of: harvesting fresh wheat seedlings, sorting, cleaning, juicing, filtering, concentrating, spraying and drying, collecting powder, checking and accepting, and packaging and storing. According to the process disclosed by the invention, the time from harvesting the fresh wheat seedlings to collecting the powder is controlled within 5 hours. The whole process is a physical process, the mechanical degree is high, the extracting rate is high and the temperature is controlled to 25 DEG C to 45 DEG C. The preparation process disclosed by the invention can be used for efficiently extracting SOD in the wheat seedlings and sufficiently storing and keeping the function activities; besides, the process is green and environment-friendly, the wheat seedlings can be recycled and the residues can be used as feed, so that industrial pollution is avoided.

Description

technical field [0001] The invention belongs to the technical field of extracting plant active substances, and more specifically relates to a process for extracting active SOD from wheat seedlings. Background technique [0002] Superoxide dismutase (English abbreviation SOD) is known as the "scavenger" of human garbage, "the king of anti-aging" and "the favorite of beauty". As a free radical scavenger, it is an important active substance that can improve human health. An important class of functional food base materials. As early as the mid-to-late 1960s, scientists successively extracted SOD from animal blood. However, the common defects of these SODs are high price and unstable safety. Therefore, the World Health Organization (WHO) appeals not to extract SOD from animal plasma, and the European Union has also announced that it will phase out the use of animal protein and promote the use of vegetable protein. [0003] In recent years, breakthroughs have been made in plant...
