Problems solved by technology

[0003] The existing process takes a long time to produce, and a large amount of toxic preservatives and flocculants are added in the production. The suspended impurities and activated carbon decolorized by flocculation absorb part of the product, and the yield is low; plate and frame filter is used to remove the suspended flocculants and other suspended Impurities, the production environment is very poor, and the production environment is difficult to meet the production requirements of food additives; the extensive use of ion exchange and macroporous resins in production consumes a lot of water resources and chemical raw material resources, and it is difficult to elute toxic waste water from a large amount of resin Biochemical treatment brings heavy economic burden and environmental pressure to enterprises

Embodiment Construction

[0024] specific implementation plan

[0025] now attached figure 1 The present invention will be further described in detail with specific embodiments.

[0026] Such as figure 1 Shown, a kind of novel naringin extraction method, extraction process step comprises:

[0027] Step 1, pretreatment: pulverizing and sieving the pomelo peel with a mechanical pulverizer, crushing the pomelo peel into pulp with slag, and then sieving to obtain a crude pomelo peel pulp;

[0028] Step 2, enzymatic hydrolysis: put pomelo peel pulp into a circulation tank for enzymolysis treatment, put in enzymes to enzymatically hydrolyze the crude pomelo peel pulp, and then sieve to obtain pomelo peel pulp;

[0029] Step 3, adjust PH: adjust the PH of the obtained pomelo peel pulp to ensure that there is a certain buffer in the pulp;

[0030] Step 4, inactivation: adjust the temperature, and inactivate the enzymes that have been put into the pomelo peel pulp;

[0031] Step 5, separation and concentra...

Abstract

The invention discloses a novel method for extracting naringin. The extraction process steps include: step 1, crushing; step 2, enzymatic hydrolysis; step 3, adjusting PH; step 4, inactivation; step 5, separation and concentration; step 6 , decolorization; step seven, concentration and centrifugation; step eight, spray drying; step nine, pulverization. The novel naringin extraction method of the present invention has high filtration precision and fundamentally ensures the purity and quality of the filtrate; the membrane process is a purely physical process without phase change and low energy consumption, and the system operates at normal temperature. It overcomes the damage of heat to the active substances in the enzyme preparation products; compared with the traditional filtration process, not only the product quality has been improved, but also the product yield and production efficiency have been significantly improved.

Description

technical field [0001] The invention relates to the technical field of membrane treatment of naringin, in particular to a novel method for extracting naringin. Background technique [0002] Naringin is a flavonoid compound. Since there is no conjugation between ring A and ring B, there is a strong ultraviolet absorption peak at 282nm, which makes naringin display various biological activities and pharmacological effects. It has anti-inflammatory, anti-virus, anti-cancer, anti-mutation, anti-allergic, anti-ulcer, analgesic, and blood pressure-lowering activities, can lower blood cholesterol, reduce the formation of thrombus, improve local microcirculation and nutrient supply, and can be used for production and prevention of heart and brain vascular disease. [0003] The existing process takes a long time to produce, and a large amount of toxic preservatives and flocculants are added in the production. The suspended impurities and activated carbon decolorized by flocculation...
