Embodiment Construction

[0019] 1) Process flow Lotus pod and lotus shell acceptance→rinsing→drying→crushing→enzymolysis→microwave extraction→filtering→drying→microcapsule embedding→packaging

[0020] 2) Operation points

[0021] ① Acceptance of lotus pods and lotus shells: lotus pods and lotus shells should have no deterioration, no pests, and mildew; special attention should be paid to excessive pesticide residues in lotus pods and lotus shells due to improper use of pesticides or insufficient safety interval after pesticide application;

[0022] ② Rinse: Wash with tap water.

[0023] ③Drying: Dry the lotus pods and lotus shells in the dryer for crushing.

[0024] ④ Broken: crush lotus pods and lotus shells;

[0025] ⑤Enzymolysis: under the conditions of enzymolysis: pH 5, substrate concentration 10% at 50°C, compound enzyme concentration 0.0235%, enzymolysis for 3 hours;

[0026] ⑥Microwave extraction: use electromagnetic waves between 300 and 300,000MHz to freely pass through the extraction med...

Abstract

The method provides a method for extracting flavone extract from lotus seedpods. According to the method, the extraction efficiency is more than 95%, and the content of the total flavone of the flavone extract is more than or equal to 14%. The technical scheme is as follows: firstly, the technology of the combination of complex biological enzymatic hydrolysis and microwave-assisted extraction is adopted, wherein enzymatic hydrolysis is performed for three hours under the enzymatic hydrolysis conditions that the pH value is 5, the temperature is 50 DEG C, the substrate concentration is 10%, the complex enzyme concentration is 0.0235%; microwave-assisted extraction is implemented: electromagnetic waves from 300MHz to 300000MHz are adopted to freely penetrate through extracting mediums to filter and separate residues at lower temperature to obtain the extract; secondly: the microcapsule embedding technology is adopted: maltodextrin is used as a microcapsule embedding agent, and the adding coefficient is 2.0g.mL<-1>, wherein the microcapsule embedding technology can keep the antioxidant physiological activity of products to the maximum extent. The flavone extract extracted through the method can be used as drugs, health products and food materials.

Description

(1) Technical field [0001] The invention relates to a method for extracting flavone extract from lotus pods and lotus shells. (2) Technical background [0002] There are 20 to 30 small holes in the lotus fruit holder, each of which is a room, and each room has a house, hence the name. The lotus pod is fluffy in texture, so it is also called the lotus pod shell. It tastes bitter, astringent, and flat in nature. It can be used as a medicinal material, mainly used for dispelling blood stasis to stop bleeding, menorrhagia, blood in the stool, and hematuria. [0003] In view of the high content of flavonoids in lotus pods and lotus husks, research on the extraction of flavonoids from lotus pods and lotus husks has been carried out, but due to the maturity of the technology department and other reasons, it has not been used in actual production. (3) Contents of the invention [0004] The technical task of the present invention is to provide a method for extracting flavonoid ex...
