Embodiment Construction

[0005] The present invention designs three groups of treatments, that is, blueberries are stored in decompression tanks with different vacuum degrees: (1) stored in decompressed tanks without treatment (storage temperature is 0°C), that is, the control group; Stored in a decompression tank with an absolute pressure of 50kPa (storage temperature is 0°C), that is, the 50kPa group; (3) stored in a decompression tank with an absolute pressure of 75kPa (storage temperature is 0°C), that is, the 75kPa group. Each group selects fruits with the same maturity and the same size.

[0006] The rate of good fruit in the control group after storage for 49 days decreased to 71%, the content of reduced glutathione was 564mg / 100g fresh weight, and the protein content was 0.75 mg / 100g fresh weight; compared with the control group, the rate of good fruit was 72% when the atmospheric pressure was 50kPa , The content of reduced glutathione is 648mg / 100g fresh weight, and the protein content is 1.0...

Abstract

The invention relates to a reduced pressure storage preservation method for blueberry. According to the reduced pressure storage preservation method for blueberry, an absolute pressure during reduced pressure storage is 50-75kPa, and a storage temperature is 0 DEG C. By adopting the reduced pressure storage preservation method for blueberry, high healthy fruit rate is guaranteed, content of reduced glutathione and protein is increased, and shelf life is greatly prolonged.

Description

technical field [0001] The invention relates to the field of fresh-keeping processing, in particular to a fresh-keeping and storage method for blueberries and other blueberries. Background technique [0002] Blueberry is known as the "Queen of Fruits" and "The Fruit of Color Contact". It has many medicinal functions, such as protecting eyes, enhancing vision, enhancing autoimmunity, anti-oxidation function, slowing down human aging, enhancing memory, anti-cancer function, etc. However, blueberries have high moisture content, delicate tissues, are extremely vulnerable to mechanical damage and microbial infection and rot, and have a very short shelf life. Contents of the invention [0003] In order to solve the above problems, the present invention intends to provide an effective fresh-keeping method for blueberries, which can effectively prolong the shelf life of blueberries and ensure a higher good fruit rate. The specific decompression storage and fresh-keeping method...
