Embodiment 1

[0017] A kind of extraction process of citrus fruit peel of the present invention, comprises the following steps:

[0018] a: Prepare raw materials, select fresh citrus fruit peels as raw materials, remove the dirt on the surface of the peels, and remove the white skin layer in the peels;

[0019] b: heat and reflux the peel obtained in step a with 80% ethanol for 5 times, and combine the extracts to obtain the primary extract;

[0020] c: Rinse the initial extract obtained in step b with 80% ethanol and water for reuse, then adsorb it with a macroporous resin and elute it with 50% ethanol on the macroporous resin column, combine and mix the eluents to obtain a crude extract thing;

[0021] d: Compress the crude extract obtained in step c to 1 / 5 of the original volume;

[0022] e: extracting the compressed filtrate obtained in step d, standing still, suction filtering and drying to obtain the finished product.

Embodiment 2

[0024] A kind of extraction process of citrus fruit peel of the present invention, comprises the following steps:

[0025] a: Prepare raw materials, select fresh citrus fruit peels as raw materials, remove the dirt on the surface of the peels, and remove the white skin layer in the peels;

[0026] b: heat and reflux the peel obtained in step a with 85% ethanol for 4 times, and combine the extracts to obtain the primary extract;

[0027] c: Rinse the primary extract obtained in step b with 85% ethanol and water for reuse, then adsorb it with a macroporous resin and elute it with 55% ethanol on the macroporous resin column, combine and mix the eluents to obtain a crude extract thing;

[0028] d: Compress the crude extract obtained in step c to 1 / 4 of the original volume;

[0029] e: extracting the compressed filtrate obtained in step d, standing still, suction filtering and drying to obtain the finished product.

Embodiment 3

[0031] A kind of extraction process of citrus fruit peel of the present invention, comprises the following steps:

[0032] a: Prepare raw materials, select fresh citrus fruit peels as raw materials, remove the dirt on the surface of the peels, and remove the white skin layer in the peels;

[0033] b: heat and reflux the peel obtained in step a with 90% ethanol for 3 times, and combine the extracts to obtain the initial extract;

[0034] c: Rinse the primary extract obtained in step b with 90% ethanol and water for reuse, then adsorb it with a macroporous resin and elute it with 60% ethanol on a macroporous resin column, combine and mix the eluents to obtain a crude extract thing;

[0035] d: Compress the crude extract obtained in step c to 1 / 3 of the original volume;

[0036] e: extracting the compressed filtrate obtained in step d, standing still, suction filtering and drying to obtain the finished product.

[0037] The fruit peel is effectively treated, the active ingredi...

Abstract

The invention discloses a process for extracting peel of fruits such as citrus. The method comprises the following steps: a, preparing raw material, namely selecting fresh peel of fruits such as citrus as raw material; b, performing heating reflux extraction on the peel which is completely cleaned in the step a for 3-5 times by using 80-90% ethanol, mixing the extracted solutions, thus obtaining a primary extract; c, washing and recycling the primary extract obtained in the step b by using 80-90% ethanol and water, adsorbing by using a macroporous resin, eluting the macroporous resin column by using 50-60% ethanol, mixing the eluants, thus obtaining a crude extract; d, compressing the crude extract obtained in the step c to 1 / 5-1 / 3 of the original volume; and e, extracting the filtrate compressed in the step d, standing, performing suction filtration, and drying to obtain the finished product. The process has the advantages that the peel is effectively treated, the active ingredients are preserved, the production process flow is simple and convenient, the extraction purity is high and the operation is simple and convenient.

Description

technical field [0001] The invention relates to a process for extracting citrus fruit peels. Background technique [0002] Citrus fruits are rich in nutrients and unique taste. In addition to fresh food, canned food, fruit juice, jam, fruit wine, candied fruit, etc. have become the main fruit processing products; citric acid and essential oils extracted from them , pectin, etc. can be used as raw materials for food and pharmaceutical industries. Tangerine peel, orange network, etc. are Chinese herbal medicines. After people eat the citrus fruits, they often discard the peels, and the citrus peels are rich in active ingredients, which wastes effective resources. [0003] Therefore, there is an urgent need for an improved technology to solve this problem in the prior art. Contents of the invention [0004] The purpose of this invention is to provide a kind of extraction process of citrus fruit peel. [0005] The technical scheme adopted in the present invention is: [0...
