Embodiment 1

[0017] 1. The preparation of the preservative includes the following steps:

[0018] a) pulverization process: the orange peel is washed, and pulverized into particle size of 20 meshes;

[0019] b) alcohol extraction process: adding 5 times of the total weight of orange peel is 60% ethanol, soaking for 20 hours, and filtering;

[0020] c) Concentration process: the extract prepared in the alcohol extraction process is concentrated to a density of 1.05 g / cm 3 the extract;

[0021] 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 the silica gel is 1:2, and the eluent is ether, ethyl acetate, and ammonia. The volume ratio of the mixture is 1:0.5:0.01.

[0022] e) Collection process: the components of the second color band are collected, and the collected material is subjected to vacuum distillation under the condition of a water bath te...

Abstract

The invention discloses an apple juice beverage. The apple juice beverage contains fresh-keeping agent extracted from orange peels. Compared with the prior art, the fresh-keeping agent extracted from orange peel can prolong the shelf life of apple juice beverages, particularly keep the remaining apple juice in the large-volume apple juice beverage stored at room temperature for more than 3 days after opening.

Description

technical field [0001] The invention belongs to beverages, in particular to apple juice beverages. Background technique [0002] Apple juice beverages contain important vitamins A and C, which can maintain the daily needs of the human body and play an effective role. Apple juice beverages are generally made of concentrated apple juice diluted with water. The usual ingredients are water, white sugar, and apple juice. , calcium lactate, citric acid, flavor, vitamin C, caramel color. Since apple juice contains a lot of vitamin C, it is best to drink it within half an hour after opening, otherwise the apple juice will easily deteriorate, but for large-capacity apple juice drinks, it is often impossible to drink it at one time, causing waste. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide an apple juice beverage that is not easily deteriorated. [0004] The technical solution of the present invention to solve the te...
