Problems solved by technology

[0003] However, the storage period of wild blueberries is short and the storage capacity is small, especially after a period of storage, the fruit grains become soft and more difficult to store, and they are easy to rot and deteriorate
At present, the method of storing blueberries in a large area is to store blueberries in cold storage and store them at low temperature, but it also has certain disadvantages. There is no antiseptic and sterilization process, and the blueberries are directly stacked and stored, which has certain food safety hazards

Embodiment Construction

[0015] The technical scheme that the present invention adopts is as follows:

[0016] a. Selection: select the blueberry fruit grains with blue color, and remove the leaves and stems;

[0017] b, canning: put the selected blueberry fruit into the container;

[0018] c. Sterilization: pasteurize for 30 minutes at a temperature of 60-65°C;

[0019] d, storage: put the sterilized canned blueberry fruit into the cold storage;

[0020] e. Anti-corrosion: place an antimicrobial agent between the tanks;

[0021] f. Storage: Control the temperature of the cold storage at 2-5°C for low-temperature storage.

[0022] The advantages of the present invention are:

[0023] 1. Without destroying the color of blueberries. In the case of nutritional components, low-temperature storage is adopted to prolong the storage time of blueberries, and an antimicrobial agent is added during storage to prevent deterioration of blueberries. The method is low in cost, simple in method, and convenient ...

Abstract

The invention relates to the field of food storage, in particular to a storage method of fresh blueberry. Low-temperature storage is applied without damaging appearance, color and nutrients of the blueberry, and storage time of the blueberry is prolonged. Antimicrobial is added in storage to prevent deterioration of dices of the blueberry. The storage method is low in cost, simple in process and convenient to popularize and use. By pasteurization, pathogenic microorganisms such as bacterium burger, mycobacterium tuberculosis, shigella dysenteriae and typhoid bacillus can be killed, and the total number of germs can be decreased to by 90%-95%. Therefore, disease transmission is decreased, and service time of articles is prolonged. In addition, the pasteurization causes no damage to effective ingredients of sterilized foods, and the storage method is simple.

Description

technical field [0001] The invention relates to the field of food storage, in particular to a storage method for fresh-keeping blueberries. Background technique [0002] Wild blueberry grows in a pure natural environment and is a pure natural food. It is low in calories but high in nutrients. There are also a lot of antioxidant substances, which can prevent cataracts, glaucoma, varicose veins, hemorrhoids, gastric ulcers, heart disease and cancer. Blueberries may also help moderate brain damage after a stroke and reduce inflammation in the digestive tract -- treating constipation and diarrhea. It also contains a variety of amino acids, trace elements and vitamins necessary for the human body, and also contains extremely rich antioxidant components VC, VE and carotene. Plants are many times, after research, it is found that the strengthening ability of eliminating free radicals of human metabolic by-products, the unique edible anthocyanins and anthocyanins of its fruits ca...
