Embodiment 1

[0019] 〔1〕Take 100g of seabuckthorn puree and put it into the extractor for supercritical CO 2 Extraction, extraction pressure 16MPa, extraction temperature 32°C, separation pressure 6MPa, separation temperature 25°C, to obtain 16g of sea buckthorn fruit oil and 80g of defatted fruit puree;

[0020] [2] Extract the defatted fruit puree with 10 times the weight of hot water (30° C.) for 1 hour, filter, and dry the filtrate to obtain 7 g of water-soluble product;

[0021] [3] Reflux the fruit puree after water extraction with 6 times the weight of 65v% ethanol, filter, recover ethanol, wash the obtained solid with water, and dry to obtain crude flavonoids, which are then dissolved in ethyl acetate and filtered , concentrated the filtrate by distillation under reduced pressure, and crystallized to obtain a light yellow flavonoid product with a flavonoid content of 42%;

[0022] [4] The residue obtained in step (3) is dried and used as feed.

Embodiment 2

[0024] 〔1〕Take 100g of seabuckthorn puree and put it into the extractor for supercritical CO 2 Extraction, the extraction pressure is 18MPa, the extraction temperature is 38°C, the separation pressure is 7MPa, and the separation temperature is 68°C to obtain 18g sea buckthorn fruit oil and 75g defatted fruit puree;

[0025] [2] Extract the defatted fruit puree with 12 times the weight of hot water (32° C.) for 1.5 hours, filter, and dry the filtrate to obtain 7.5 g of a water-soluble product;

[0026] [3] The fruit puree slag after water leaching is filtered with 8 times the weight of 70v% ethanol, and the ethanol is recovered. The obtained solid is washed with water and dried to obtain the crude flavonoids. The crude flavones are then dissolved in ethyl acetate, filtered, Distill under reduced pressure, concentrate the filtrate, and crystallize to obtain a light yellow flavone product with a flavone content of 41%;

[0027] [4] The residue obtained in step (3) is dried and u...

Embodiment 3

[0029] 〔1〕Take 100g of seabuckthorn puree and put it into the extractor for supercritical CO 2 Extraction, extraction pressure 25MPa, extraction temperature 45°C, separation pressure 9MPa, separation temperature 60°C, to obtain 19g of sea buckthorn fruit oil and 73g of defatted fruit puree;

[0030] [2] Extract the defatted fruit puree with 14 times the weight of hot water (40° C.) for 1 hour, filter, and dry the filtrate to obtain 7.8 g of water-soluble product;

[0031] [3] The fruit puree slag after water leaching is filtered with 10 times the weight of 75% ethanol, and the ethanol is recovered. The obtained solid is washed with water and dried to obtain crude flavonoids. The crude flavones are then dissolved in ethyl acetate, filtered, Concentrate the filtrate by distillation under reduced pressure, and crystallize to obtain a light yellow flavone product with a flavone content of 43%;

[0032] [4] The residue obtained in step (3) is dried and used as feed.

Abstract

The deeply processing of mashed sea-buckthorn fruit includes supercritical CO2 extraction of mashed sea-buckthorn fruit to obtain sea-buckthorn fruit oil and defatted sea-buckthorn fruit paste; water extraction of defatted sea-buckthorn fruit paste; filtering and drying filtrate to obtain sea-buckthorn fruit tea with rich organic acid, vitamin C, sea-buckthorn polysaccharide, pectin, etc.; and alcohol extraction of the filter residue to obtain sea-buckthorn flavone in 40-50 % content and residue. The sea-buckthorn flavone is used as health food and medicine material, and the residue is used as feed additive. The present invention has simple process, and the products sea-buckthorn fruit oil, sea-buckthorn fruit tea, sea-buckthorn flavone and feed additive are marketable.

Description

technical field [0001] The invention belongs to a method for deep processing of seabuckthorn puree. Background technique [0002] Seabuckthorn fruit puree is a product obtained from seabuckthorn juice through sedimentation and fermentation. It is rich in vitamin C, seabuckthorn flavonoids, organic acids, seabuckthorn polysaccharides, pectin, fruit oil and other ingredients. It is currently mainly used to extract seabuckthorn flavonoids, and for it Seabuckthorn fruit oil, seabuckthorn polysaccharides, vitamin C and organic acids are not fully utilized. [0003] Seabuckthorn flavonoids have important physiological activities, such as anti-myocardial ischemia, lowering blood fat, anti-tumor, regulating immune system, etc., can remove free radicals in the body, prevent and treat cardiovascular diseases, and also have the effect of directly removing free radicals. It is stronger than vitamin E and has obvious anti-aging effect. The content of isorhamnetin in seabuckthorn flavon...
