Description

A kind of Hylocereus undatus fruit vinegar and preparation method thereof

Technical field

The present invention relates to food processing technology field, particularly relate to a kind of Hylocereus undatus fruit vinegar and preparation method thereof.

Background technology

Current vinegar constantly changes to health and becomes trend, and fruit vinegar has the health vinegar of excellent flavor as a kind of and extensively get consumer reception, and its rich in nutrition content is mellow, fresh tasty and refreshing.Hylocereus undatus fruit vinegar take Hylocereus undatus as raw material, through the acid goods of nutritious, the excellent in flavor of fermentation brew.The fruit vinegar fermentation at present normal liquid fermentation method that adopts is produced, and containing a large amount of microorganism based on acetic bacteria in the fresh fruit vinegar of just fermentation, microbial growth breeding can cause the material consumption of vinegar liquid Middle nutrition, and flavor deterioration, has a strong impact on quality product.In addition, new vinegar mouthfeel is stiff, and the smell of vinegar stimulates, and fragrance is thin, needs to carry out ageing to improve fruit vinegar flavor., there is the defects such as power consumption is high, operation inconvenience in the degerming employing thermal treatment of tradition vinegar.Ozone belongs to strong oxidizer, has broad-spectrum bactericidal action, has easy to use, speed of action feature faster, therefore utilizes ozone to carry out sterilization to fruit vinegar and has broad prospects.。

Summary of the invention

The object of the invention is exactly the defect in order to make up prior art, provides a kind of Hylocereus undatus fruit vinegar and preparation method thereof.

The present invention is achieved by the following technical solutions:

A kind of Hylocereus undatus fruit vinegar, be made up of the raw material of following weight part:

Hylocereus undatus 300-310, honey 5-6, tealeaves 7-8, Root of Indigowoad 2-3, taraxacum 1-2, radix bupleuri 3-4, Japanese Honeysuckle 2-3, white sugar 24-25, yeast 1-1.2, acetic bacteria 3-4, chitosan 0.4-0.5, medical stone powder 9-10.

The preparation method of described Hylocereus undatus fruit vinegar, comprises the following steps:

(1) Root of Indigowoad, taraxacum, radix bupleuri, Japanese Honeysuckle are added 5-6 water slow fire boiling 40-50 minute doubly, filter cleaner, gained filtrate is spray-dried makes powder, obtains Chinese medicine powder;

(2) tealeaves is added 4-5 times of water lixiviate 15-20 minute at 70-75 DEG C, filter cleaner, collect filtrate;

(3) removed the peel by Hylocereus undatus, add the water making beating of 2 times, at 80 DEG C, sterilizing 10 minutes, was cooled to 30 DEG C, adds white sugar, yeast, loads fermentor tank, 30-32 DEG C of bottom fermentation 96 hours, then accesses acetic bacteria, 33 DEG C of bottom fermentations 110 hours;

(4) acetic acid solution chitosan being added 4% is stirred to dissolving, and wherein solid-to-liquid ratio is 1:10, gained solution and medical stone powder mixing and stirring, crushed after being dried;

(5) by step (3) gained material filter cleaner, the raw material do not used with step (1), (2) gained material and above-mentioned technique mixes, and then adds step (4) gained material, stir 10-15 minute, filter, filling, at 30 DEG C, pass into ozone gas 15 minutes, sealing, to obtain final product.

Advantage of the present invention is: the present invention adopts ozone to carry out sterilization, not only can obtain good sterilization effect, and the esterification under the oxygenizement of ozone of acetic acid and ethanol becomes ethyl acetate, increase substantially the total ester content of fruit vinegar, make fruit vinegar color burn, improve fruit vinegar flavor, and the present invention also adopts medical stone loading chitosan, play the adsorption of medical stone and the sequestering action of chitosan, there is good clarifying effect, significantly decrease the consumption of chitosan simultaneously, reduce costs, also can avoid being used alone the Random Effect factor that chitosan easily occurs, in addition, the present invention is also containing medicinal herb components, there is the effect of preventing cold.
