Problems solved by technology

However, simply extracting and separating an active substance from Lycium barbarum will undoubtedly cause a great waste of resources, and after extracting the active substance, the remaining waste residue is large and difficult to handle, which will cause great pressure on the ecological environment

Embodiment 1

[0026] 1) Take 400 kg of high-quality wolfberry fruit, wash them with tap water and pure water in turn, dry, crush, and pass through a 15-mesh sieve;

[0027] 2) Add the crushed and sieved Lycium barbarum into the subcritical extraction device, and then add 25m 3 Butane; after filling with nitrogen for 3 hours, perform subcritical extraction: the extraction pressure is 5 MPa, and the extraction time is 2 hours. After the extraction, the solvent was removed to obtain wolfberry residue (about 0.4 T) and the fat-soluble components of wolfberry; the fat-soluble components of wolfberry were collected and sterilized by irradiation to obtain 6 kg of wolfberry red pigment. The extraction rate of Lycium barbarum is 92%, and the yield is 1.5%;

[0028] 3) Put the above-mentioned 0.4 T wolfberry residue into a multifunctional extraction tank with a capacity of 6 T, add 2 T pure water, turn on the high-speed shear system, run it at a speed of 10000 RPM for 0.5 h, and turn off the high-sp...

Embodiment 2

[0034] 1) Take 40 kg of high-quality wolfberry fruit, wash them with tap water and pure water in turn, dry, crush, and pass through a 15-mesh sieve;

[0035] 2) Put crushed and sieved Lycium barbarum powder into a 1T multifunctional extraction tank, add 5 times the amount of pure water, and shear at a high speed of 10,000rpm for 30 minutes; then add 5 times the amount of pure water, stir and heat up to 60°C, and extract 2h, stand still for 2h, drain the wolfberry extract from the liquid outlet on the side of the extraction tank, and discharge the material when the temperature drops below 30°C, and the extraction process is completed.

[0036] 3) The wolfberry extract is first centrifuged with a three-legged centrifuge (filter cloth aperture is 200 mesh), and then centrifuged with a tubular centrifuge (centrifugal speed is 16000rpm), and the wolfberry residue obtained from the two centrifuges is combined; the collection tube Centrifuge liquid.

[0037] 4) Put the wolfberry res...

Abstract

The invention discloses a method for synchronous separation and preparation of zeaxanthin dipalmitate, Lycium barbarum polysaccharides and Lycium barbarum flavones from Lycium barbarum. The method employs the integrated technology of subcritical extraction, high-speed shearing, low-temperature extraction, tubular centrifugation, membrane filtration separation, macroporous adsorption resin mixed-bed purification and drying, etc. to synchronously prepare three active substances in Lycium barbarum, i.e., zeaxanthin dipalmitate capable of improving eyesight, Lycium barbarum glycopeptide capable ofprotecting the liver and Lycium barbarum flavones capable of slowing down the aging process; the method greatly improves the utilization of Lycium barbarum, obviously shortens extraction time and significantly lowers cost; and the three active extracts have high purity, complete active structure and stable physicochemical properties, and can be used as raw materials for food, health food, food ofspecial medical purposes and medicines.

Description

technical field [0001] The invention relates to a method for synchronously separating active extracts from wolfberry, in particular to a method for synchronously separating wolfberry red pigment, wolfberry polysaccharide and wolfberry flavonoids from wolfberry, and belongs to the technical fields of food, health food and medicine. Background technique [0002] Lycium barbarum, sweet in taste, has the functions of nourishing the liver and kidney, improving eyesight, regulating the body's immunity, delaying aging, and anti-fatty liver. The Ministry of Health first listed it as one of the homologous varieties of medicine and food. It has been eaten in my country for more than 2,000 years and has been included in the "Chinese Pharmacopoeia" in previous editions. Modern natural product chemistry, biology, and pharmacology studies have found that wolfberry contains wolfberry glycopeptides, wolfberry flavonoids, wolfberry red pigment, amino acids, vitamins, trace elements, etc., and...
