Embodiment 1

[0106] After crushing 10kg of grapefruit whole fruit into a 40-mesh homogenate, add 250kg of purified water to it, stir evenly, put it in a micro-fluidic extractor, and extract it at a refrigerant temperature of 10°C and a feed rate of 20L / min to obtain extract. The extract is subjected to solid-liquid separation through a centrifuge at a speed of 8000rpm, collected and separated, and the separated liquid is separated and purified with a ceramic membrane with a pore size of 500nm, the filtrate is collected, and concentrated with a reverse osmosis membrane until the ratio of the raw material to the concentrated liquid is 1:3, that is, grapefruit extract.

Embodiment 2

[0108] Add 20kg of whole grapefruit fruit with 100kg of purified water and crush it into a 40-mesh homogenate, add 300kg of purified water to the homogenate, stir evenly, and place it in a micro-fluidic extractor at a refrigerant temperature of 15°C and a feed rate of 20L / min conditions to obtain the extract. The extract is subjected to solid-liquid separation through a centrifuge at a speed of 8000rpm, collected and separated, and the separated liquid is separated and purified with a ceramic membrane with a pore size of 500nm, the filtrate is collected, and concentrated with a reverse osmosis membrane until the ratio of the raw material to the concentrated liquid is 1:3, that is, grapefruit extract.

Embodiment 3

[0110] After crushing 10kg of grapefruit whole fruit into a 40-mesh homogenate, add 250kg of 30% ethanol solution, stir evenly, place in a micro-fluidic extractor, and extract under the conditions of a refrigerant temperature of 20°C and a feed rate of 15L / min, to obtain extract. The extract is subjected to solid-liquid separation through a centrifuge at a speed of 8000rpm, collected and separated, and the separated liquid is separated and purified with a ceramic membrane with a pore size of 500nm, the filtrate is collected, and concentrated with a reverse osmosis membrane until the ratio of the raw material to the concentrated liquid is 1:3, that is, grapefruit extract.

Abstract

The invention belongs to the technical field of plant extraction and especially relates to a grapefruit extracting method. The grapefruit extracting method disclosed by the invention comprises the following steps: a) smashing grapefruit whole fruit to obtain homogenate; b) performing micro-jet extraction on the homogenate to obtain extractive. The extracting method has advantages of high extracting efficiency, small damage to an effective ingredient of general flavones in the grapefruit, ability in keeping functional components of the grapefruit, energy conservation and environmental friendliness. A mass fraction of the general flavones of the grapefruit extractive obtained by the extracting method can reach 50%, a content of the effective ingredient of the general flavones is high, and grapefruit function exerting is facilitated; experiments show that the grapefruit extractive has a strong anti-allergy function and especially shows obvious anti-inflammation and antibacterial functionsin the aspects of resisting delayed hypersensitivity and reducing capillary permeability. The invention further provides application of the grapefruit extractive obtained by the extracting method inpreparing anti-allergy products, anti-inflammation products and/or antibacterial products.

Description

technical field [0001] The invention belongs to the technical field of plant extraction, in particular to a method for extracting grapefruit. Background technique [0002] Skin allergy is a common skin disease at present, which seriously affects people's physical and mental health. Anaphylaxis is divided into immediate and delayed. At present, drug treatment is mainly adopted for allergies, and anti-allergic drugs include antihistamines, steroids, etc., but these drugs often have relatively large side effects. Along with the raising of people's living standard, nontoxic, harmless natural plant with antiallergic effect is more and more subject to people's favor. The Chinese Journal of Experimental Formulas reported (February 2013, Volume 19, Issue 4) that the combined prescription of Fangfeng and Kochia chinensis has therapeutic effects on skin allergy and itching, and the water extract of peach kernels on the production of skin allergy antibodies in mouse serum Has an inh...
