Problems solved by technology

Although there are many methods for extracting flavonoids, the research on extracting flavonoids from banana peels has not been reported yet. Extracting flavonoids from banana peels can open up a new way for the comprehensive utilization of bananas, and also provide a basis for the use of banana peel extracts in food. The development and utilization in the field of natural preservatives provides an experimental basis

Embodiment 1

[0015] a. Raw material pretreatment: clean the ripe banana peels, shred them, place them in an oven at 50°C, and fully dry them for 24 hours. After the dried banana peels are routinely pulverized, the coarse powder obtained is ultrafinely pulverized with an airflow mill for 40 minutes. Obtain the banana peel powder, bottle it and place it in a desiccator for subsequent use;

[0016] b. Enzymolysis: Weigh the dried banana peel powder, put it into a conical flask, add distilled water to make the ratio of solid to liquid 1:30, shake well, add pectinase to make the enzyme concentration 0.1mg / ml, use plastic Cloth seal, carry out enzymolysis, enzymolysis temperature is 50 ℃, enzymolysis time is 90min, pH value is 3.5;

[0017] c. Water bath leaching: After enzymatic hydrolysis, centrifuge to remove the supernatant, add distilled water to the sediment to make the ratio of solid to liquid 1:20, fully dissolve and carry out water bath leaching, adjust the pH value to 10.5, heat in wat...

Embodiment 2

[0022] a. Raw material pretreatment: clean the ripe banana peels, shred them, place them in an oven at 55°C, and dry them fully for 20 hours. After the dried banana peels are conventionally pulverized to obtain coarse powder, use an airflow mill for ultrafine pulverization for 35 minutes. Obtain the banana peel powder, bottle it and place it in a desiccator for subsequent use;

[0023] b. Enzymolysis: Weigh dried banana peel powder, put it into a conical flask, add distilled water to make the ratio of solid to liquid 1:25, shake well, add cellulase to make the enzyme concentration 0.15mg / ml, use plastic Cloth seal, carry out enzymolysis, enzymolysis temperature is 55 ℃, enzymolysis time is 35min, pH value is 5.0;

[0024] c. Water bath leaching: After enzymatic hydrolysis, centrifuge to remove the supernatant, add distilled water to the sediment to make the ratio of solid to liquid 1:25, fully dissolve and carry out water bath leaching, adjust the pH value to 11.0, heat in a w...

Abstract

The invention discloses a method for extracting anthoxanthin from banana skin. The method comprises the following steps: raw material pretreatment, enzymolysis, water bath extraction, clarification, adsorption, concentration, freeze drying and conservation. The invention adopts a water bath extracting and big hole resin adsorbing combined method after enzymolysis for extracting anthoxanthin in the banana skin, and the obtained anthoxanthin extractive is tan, is higher in content and purity, is better in quality and conforms to Food Sanitation Standards. The anthoxanthin can improve the blood circulation of people, reduce cholesterol and lower the sickness rate of cardio-cerebrovascular diseases, and also can improve the symptom of cardio-cerebrovascular diseases, and can be used in functional food additives such as natural sweetener, natural anti-oxidant and natural coloring matters. The method provided by the invention is unique, is easy to implement, is small in energy consumption and high in benefits, improves the added value of bananas, and has a great market prospect.

Description

technical field [0001] The invention relates to a method for extracting flavonoids from fruits, in particular to a method for extracting flavonoids by using banana peel as a raw material, using enzymatic hydrolysis, auxiliary water bath extraction and macroporous resin adsorption to extract flavonoids, belonging to the field of agricultural product processing. Background technique [0002] Banana is the fruit of the perennial tree-like herbaceous plant banana in the family Musaceae, which has extremely high edible and medicinal value. The edible part of the banana accounts for more than 60% of the total wet weight, and it is characterized by high carbohydrate and low protein and low fat content. For a long time, bananas have been loved by people for their unique flavor and nutritional value. With the rapid development of the banana deep processing industry, a large amount of banana peels have been produced simultaneously. Banana peel mainly contains phenols, oils, organic ...
