Problems solved by technology

[0002] Orange peel is the remaining product of orange juice. The treatment of orange peel has always been a difficult problem for manufacturers. Some directly throw away the orange peel, and some use methods such as salting, sugaring, drying and grinding the orange peel. However, the above method does not make full use of the unique properties of the orange peel itself, and cannot extract specific beneficial ingredients from the orange peel

Embodiment 1

[0014] The processing method of orange peel comprises the following operations:

[0015] a) crushing process: the orange peel is washed and crushed into particles with a particle diameter of 20 mesh;

[0016] b) Alcohol extraction process: adding 60% ethanol with a volume concentration 5 times the total weight of the orange peel, soaking for 20 hours, and filtering;

[0017] c) Concentration process: concentrate the extract prepared in the alcohol extraction process to a density of 1.05g / cm 3 the extract;

[0018] d) Purification process: the extract prepared in the concentration process is subjected to column chromatography with silica gel, and eluted with an eluent, the weight ratio of the extract to silica gel is 1:2, and the eluent is ether, ethyl acetate, ammonia water The mixture, its volume ratio is 1:0.5:0.01.

[0019] e) Collection process: the components of the second color band are collected, and the collection is subjected to vacuum distillation at a water bath ...

Embodiment 2

[0021] The processing method of orange peel comprises the following operations:

[0022] a) crushing process: the orange peel is washed and crushed into particles with a particle diameter of 60 mesh;

[0023] b) Alcohol extraction process: adding 70% ethanol with a volume concentration 8 times the total weight of the orange peel, soaking for 15 hours, and filtering;

[0024] c) Concentration process: concentrate the extract prepared in the alcohol extraction process to a density of 1.1g / cm 3 the extract;

[0025] d) Purification process: The extract prepared in the concentration process is subjected to column chromatography with silica gel, and eluted with an eluent. The weight ratio of the extract to silica gel is 1:2.5, and the eluent is ether, ethyl acetate, ammonia water The mixture, its volume ratio is 1:0.7:0.03.

Embodiment 3

[0028] The processing method of orange peel comprises the following operations:

[0029] a) crushing process: the orange peel is washed and crushed into particles with a particle size of 100 mesh;

[0030] b) Alcohol extraction process: adding 95% ethanol with a volume concentration 5 times the total weight of the orange peel, soaking for 10 hours, and filtering;

[0031] c) Concentration process: concentrate the extract prepared in the alcohol extraction process to a density of 1.2g / cm 3 the extract;

[0032] d) Purification process: The extract prepared in the concentration process is subjected to column chromatography on silica gel, and eluted with an eluent. The weight ratio of the extract to silica gel is 1:2.5, and the eluent is ether, ethyl acetate, ammonia water The mixture, its volume ratio is 1:0.8:0.05.

[0033] e) Collection process: the components of the second color band are collected, and the collection is subjected to vacuum distillation at a water bath temp...

Abstract

The invention discloses a processing method of orange peels. The processing method comprises the following steps: a) pulverization step; b) alcohol extraction step; c) concentration step; d) purification step; and e) collection step. The d) purification step further comprises the following steps: subjecting the extract obtained in the concentration step to silica gel column chromatography and eluting with an eluant, wherein the weight ratio of extract to silica gel is not less than 1:2, the eluant is the mixture of ether, ethyl acetate and ammonia water at a volume ratio of 1:(0.5-0.8):(0.01-0.05). Compared with the prior art, the processing method can completely extract the effective components of the orange peels, the orange oily extract can be widely applied to the fresh-keeping of beverage foods, particularly the preservation of orange juice, grape juice, apple juice and kiwi juice.

Description

technical field [0001] The invention belongs to a food processing method, in particular to a processing method of orange peel. Background technique [0002] Orange peel is the remaining product of orange juice. The treatment of orange peel has always been a difficult problem for production enterprises. Some of them throw away the orange peel directly, and some use methods such as salting, sugaring, drying and grinding the orange peel. process, but the above method does not make full use of the unique properties of the orange peel itself, and can not extract the specific beneficial ingredients in the orange peel. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a treatment method that can make full use of the unique properties of the orange peel itself. [0004] The technical scheme that the present invention solves technical problem: the processing method of orange peel, comprises following operation: [0005] a) Pulver...
