Embodiment Construction

[0017] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0018] see figure 1 , a method for preparing pine bark extract using membrane separation and integration technology. The raw material is fresh and pollution-free pine bark after crushing, and the particle size is 16-40 mesh pine bark raw material; the pine bark raw material is purified by hot boiling deoxygenation The process parameters for water extraction and pure water extraction are: the ratio of the weight of the pine bark raw material to the volume of the liquid is 1:2 to 1:15, the temperature is between 60 and 100°C, and the time is 30 to 200min / time. Extract 2 to 3 times; Concentrate the filtered extract after pure water extraction, the process parameters used for film concentration are: vacuum degree is -0.08 ~ 0Mpa, temperature is 30 ~ 100°C, and the concentration of the concentrated solution is 1.01~1.50; then add flocculant and then flocculate and cla...

Abstract

The invention relates to a method which prepares pinaster bark extracts by a film separation integration process technique. The pinaster bark is taken as the raw material, deoxidized by boiling and extracted in pure water, so as to gain the filtration extract which is concentrated by the film subsequently; the concentrated extract is defecated by adding flocculant; further defecation and impurityremoval of the extract are carried out by plate frame filtration and micro-filtration impurity removal; subsequently, macro molecule component with poor biological activity by super-filtration; the component with the molecular weight of 40,000-150,000 is withheld by the super-filtration film; during the super-filtration, the pressure is controlled within 0.2-0.5MPa; the super-filtrated material isconcentrated by nanometer filtration; the component with the molecular weight of 300-8,000 is withheld by the nanometer filtration film; during the nanometer filtration, the pressure is controlled within 0.8-3.5MPa; finally, the nanometer-filtrated material is sprayed and dried so as to prepare the pinaster bark extract product. The method of the invention ensures the purity and activity of the pinaster bark extract; the whole production process realizes the cleaning production process and industrial water circulation and recycling usage; furthermore, the product has no chemical residues, andthe method of the invention is a production method which is extremely environment-friendly.

Description

【Technical field】 [0001] The invention belongs to the technical field of membrane separation, and relates to a method for preparing pine bark extract from pine bark by adopting membrane separation integration technology. 【Background technique】 [0002] Pine bark extract is a safe and highly effective natural antioxidant. Animal and in vitro experiments, epidemiological evidence and preliminary clinical studies have shown that pine bark extract has various benefits to human health, such as protecting blood vessels, scavenging free radicals, preventing heart disease, high blood pressure, cancer, arthritis, retinal fundus Hemorrhage, ADHD, Alzheimer's, improve immune function, etc. Dr. Lester Packer, chairman of the World Free Radical Biology and Medicine Committee, pointed out: Pine bark extract is the most effective natural antioxidant found in various laboratories and scientific literature. At present, there are more than 500 pharmacological and clinical reports on pine ba...
