Embodiment 1

[0033] This example provides a method for extracting banana peel from banana peel. This method uses a composite solvent to extract banana peel, extracts banana peel efficiently, and provides a new way for the recovery and utilization of banana peel. Provide the basis for the wide application of banana peelin. The method for extracting sciabacetin from banana peel provided by the present embodiment comprises the following steps:

[0034] Step 1: Take dried banana peels, grind them to a particle size of 0.2-0.5 mm, add methanol, acetic acid, tetrahydrofuran and water and mix them according to the volume ratio of 0.4:0.5:0.2:1 to form a mixed solution. The extraction solvent was heated to reflux for 2 hours, wherein the solid-liquid ratio between the banana peel and the extraction solvent was 1:6. After reflux, cool to room temperature, and filter to obtain the first filtrate and the first filter residue.

[0035] Step 2: Add ammonium sulfate solution with a mass fraction of 70...

Abstract

The invention discloses a method for extracting banana peel from banana peel, and relates to the technical field of extraction of natural substances. The method for extracting banana peel from banana peel of the present invention comprises: take dry banana peel, add the mixed solution of methanol, acetic acid, tetrahydrofuran (THF) and water as the extraction solvent and heat to reflux; after cooling, filter to get the first filtrate and The first filter residue; add ammonium sulfate solution to the first filtrate, let stand to precipitate, filter to get the second filtrate; add absolute ethanol to the second filtrate, let stand to precipitate, filter to get the precipitate; precipitate with absolute ethanol and ether respectively Wash and serve. The method for extracting banana peel from banana peel provided by the present invention is simple, easy to implement and low in cost. It uses a composite solvent to extract banana peel, and the extraction efficiency of banana peel is high, providing a new way for the recycling of banana peel , and provide a basis for the wide application of banana peelin.

Description

technical field [0001] The invention relates to the technical field of natural substance extraction, in particular to a method for extracting banana peel from banana peel. Background technique [0002] Banana is one of the four major fruits in the world, the most traded fruit in the world, and the most consumed fruit in the world. In China, bananas are the fourth largest fruit after apples, grapes and citrus. Because bananas are not resistant to storage and transportation, they often cause serious losses after harvest. Therefore, some major banana-producing countries have established deep-processing enterprises in the production areas to produce banana food to reduce losses. If it is discarded as waste in the field, it will waste resources and pollute the environment. At the same time, it will also spread some latent germs, which will have a negative impact on production. Therefore, the development and utilization of food by-products and wastes such as banana peels can not...
