Naringin extraction process

Abstract

The invention discloses a naringin extraction process, which comprises: 1, crushing; 2, enzymolysis; 3, PH value adjusting; 4, inactivation; 5, separating and concentrating; 6, decoloration; 7, concentrating centrifugation; 8, spray drying; and 9 crushing. According to the present invention, the filtration precision is high so as to fundamentally ensure the good purity and good quality of the filtrate; the membrane process is the purely physical process without the phase change, the energy consumption is low, the system performs the operations at the room temperature, the damage of the heat on the active substance in the enzyme preparation product is overcome; and compared to traditional filtration process, the extraction process of the present invention has the following advantages that the product quality is improved, and the product yield and the production efficiency are significantly increased.

Description

technical field [0001] The invention relates to the technical field of membrane treatment, in particular to a naringin extraction process. 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 absorb part of the p...

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
