Embodiment 1

[0064] Application of water extraction method to extract naringin and the extraction method of other by-products

[0065] (1) Crushing and extraction of pomelo young fruit;

[0066] The raw pomelo fruit comes from Qionglai, Sichuan. After swelling 100g of 1.5-3.0cm young pomelo fruit, it is crushed with a crusher. After the crushed pomelo fruit is steamed for 30 minutes, 500mL of water is added for the first time to boil. After filtering, add 300mL of water to boil, then filter, and combine the two extracts. Each extraction time is 1h, and the extraction process maintains a slight boiling state.

[0067] (2) cooling and standing; add the extract to 20% salt of the raw material, cool and stand for 2 days, and separate the crystals; wash the crude crystals with ice water and dry to obtain the product.

[0068] (3) Production of by-products:

[0069] The filtrate was concentrated to dryness, added a certain amount of hydrochloric acid, stirred and filtered. The filtrate was c...

Embodiment 2-3

[0075] The difference from Example 1 is that the materials are different, all of which are young pomelo fruits produced in Qionglai, Sichuan, with different sizes, respectively: 0-1.5cm, 3.0-5.0cm.

Embodiment 4-5

[0077] The difference from Example 1 is that the amount of salt added during salting-out in step (2) is different, being respectively: 10%, 30%.

Abstract

The invention provides a method for extracting naringin, synephrine and pectin from young shaddock fruits. The method comprises the following steps: performing extraction on steamed young shaddock fruits for one time or a plurality of times with water, and combining extracting solution and collecting residues; adding water-soluble halogenated inorganic salt into the extracting solution to separate out naringin crystals; filtering and collecting filtrate and the naringin crystals, wherein the adding amount of the halogenated salt is 10 weight percent to 30 weight percent of the young shaddock fruits; carrying out concentration, drying and halide salt removal on the filtrate obtained by salt separation to obtain a synephrine crude product; dissolving the residues obtained by extracting into water and adjusting the pH (Potential of Hydrogen) to be 1 to 2; heating and carrying out acidolysis; decomposing starch and carrying out enzyme deactivation, de-coloring, pectin gelling, filtering and concentration to obtain the pectin. By adopting the method provided by the invention, the problems of an existing process that the use amount of organic solvents is more, the utilization rate of the raw materials is low and the like are solved.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to a method for extracting naringin, synephrine and pectin from pomelo young fruit. Background technique [0002] Naringin (Naringin) mainly exists in the fruit of Citrus grandis, a plant of Rutaceae (Ihitaceae). Belongs to flavonoids. Naringin is light yellow powder or off-white powder. It has anti-inflammatory, anti-virus, anti-cancer, anti-mutation, anti-allergic, anti-ulcer, analgesic, and blood pressure-lowering activities. It can lower blood cholesterol, reduce the formation of thrombus, and improve local Microcirculation and nutrient supply can be used to prevent and treat cardiovascular and cerebrovascular diseases. Naringin exists in grapefruit (Citrus paradisi), orange, pomelo young fruit, peel and pulp of orange. [0003] There have been many reports on the extraction of naringin. At present, several main extraction methods include alkaline extraction, alcohol...
