Problems solved by technology

The extraction method mentioned in this invention patent application has certain shortcomings. First, the raw material used is fresh pepper, which is not easy to preserve. It will reduce the vitamin C content; secondly, resin is used in the extraction method, which has high production cost and is not conducive to the promotion of the product; finally, the method does not mention the purification of the extracted vitamin C, so the product purity may not be high

Embodiment 1

[0022] Weigh 250kg of chili granules and place them in a reaction tank, add 500L of ethyl acetate, stir for 3 hours at room temperature, after filtration, the filtrate can be used to prepare chili oleoresin, weigh 235kg after the degreased filter residue evaporates the solvent, add 470kg of 2% oxalic acid solution , stirred at 4°C for 6 hours under vacuum, after filtration, weighed 452kg of the filtrate, added 452kg of soybean oil, and stirred at room temperature under vacuum for 1 hour. After concentrating under pressure, pre-freeze for 24 hours, and carry out vacuum freeze-drying to obtain 10.3 kg of capsicum natural vitamin C product with a purity of 45.6%.

Embodiment 2

[0024] Weigh 1000 kg of chili granules and place them in a reaction tank, add 2500 L of petroleum ether, stir for 3 hours at room temperature, after filtration, the filtrate can be used to prepare chili oleoresin, weigh 986 kg after the degreased filter residue evaporates the solvent, add 1972 kg of 4% citric acid solution , stirred at 4°C for 8 hours under vacuum, after filtration, the filtrate weighed 1935kg, added 1935kg of sunflower oil, stirred at room temperature under vacuum for 1 hour, after the water and oil were separated, the soybean oil phase could be used as a low-spicy pepper oleoresin product, and the aqueous solution was vacuum After concentrating under reduced pressure, it was pre-frozen for 36 hours, and vacuum freeze-dried to obtain 52.3 kg of capsicum natural vitamin C product with a purity of 46.1%.

Abstract

The invention discloses a method for extracting natural vitamin C from capsicum granules. The method comprises the following steps: (1) degreasing: placing a proper amount of capsicum granules in a reaction tank, adding a degreasing solvent, carrying out stirring at a normal temperature, and carrying out filtering separation, so as to obtain degreased residues; (2) extracting: adding a vitamin C extracting solution into the degreased residues, carrying out vacuum stirring at a low temperature, and carrying out filtering separation, so as to collect filter liquor; (3) capsaicin removing: addingvegetable oil in the filter liquor, carrying out vacuum stirring at a normal temperature, and carrying out water-oil separating, so as to collect a vitamin C aqueous solution; and (4) drying: subjecting the vitamin C aqueous solution to vacuum depressurized concentration, and then, carrying out vacuum freeze drying, thereby obtaining the natural vitamin C. According to the method disclosed by theinvention, due to degreasing pretreatment, interference to detection on the vitamin C caused by lipids is avoided, and meanwhile, the rate of extraction can be increased; due to vacuum low-temperature extraction, the loss of the vitamin C is lowered to the maximum; due to capsaicin removing treatment, the purity of the vitamin C product is improved; and the method is simple in operation, easy toimplement and low in cost.

Description

technical field [0001] The invention relates to the field of extraction and separation of natural products, in particular to a method for extracting natural vitamin C from pepper granules. Background technique [0002] Vitamin C is a kind of water-soluble active substance, which has many functions such as nutrition, medical treatment and health care, and plays an important role in maintaining normal physiological functions and health of the human body, such as enhancing human immune function, anti-oxidation, anti-aging, anti-cancer Cancer, etc., can cause disease if insufficient intake or malabsorption. VC cannot be synthesized and stored in the human body, and must be ingested from the outside world. It is widely distributed in nature and mainly exists in fresh fruits and vegetables. The content of VC in different fruits and vegetables is different. According to literature reports, the VC content in peppers ranks first among vegetables and fruits, and the VC content in 100...
