Problems solved by technology

[0006] At present, the technological process and parameters of blueberry storage and preservation of different specifications are still unclear. Through pre-harvest green biological preservative preservative treatment, accurate specification grading, precise storage environment temperature and mode control, and high-concentration 1-MCP fumigation and antiseptic treatment, the storage and preservation can be improved. Improve the quality of blueberries during the shelf life, reduce rot or mildew, and prolong the storage and shelf life, thus establishing a green and precise preservation method for blueberries

Embodiment 1

[0033] Fresh-keeping Technology of Big Fruit Blueberry

[0034]Select harvested blueberries with a maturity of 8 to 9, spray them with 800 mg / L natamycin before harvesting, and complete the picking within 2 hours after the fruit surface is dry, and remove the injured, diseased, and deformed fruits. The fruit sorting machine sorts out large fruits with a diameter of 8 mm 10%) for 60 days, and the storage temperature Adjust the temperature to 0-0.5°C to revive for 60 hours, then adjust the storage temperature to 10±0.5°C and revive for 36 hours again; remove the micro-atmosphere anti-fog fresh-keeping bag with the outer lining of the blueberry fresh-keeping basket for high-concentration 1-MCP fumigation , the concentration is 5.0 μL / L, the treatment time is 10 h, and the commercialized packaging enters the cold chain distribution and sales. After being refrigerated for 60 days and stored for 5 days, the mold rot rate of blueberries was 3.85%, and the hardness was 13.42 kg / cm 2...

Embodiment 2

[0037] Fresh-keeping Technology of Small Fruit Blueberry

[0038] Select harvested blueberries with a maturity of 8-9, spray them with 1000mg / Lε-polylysine before harvesting, and finish picking within 2 hours after the fruit surface is dry, and remove injured fruits, diseased fruits, and deformed fruits. , The fruit sorting machine sorts out small fruits with a diameter of 5 mm2 , the sugar content is 9.65%.

[0039] Effect comparison: when stored according to the above conditions, without pre-harvest natamycin treatment and post-harvest high-concentration 1-MCP treatment, the mold rot rate of blueberries was 14.38%, and the hardness was 8.81 kg / cm 2 , the sugar content is 9.02%.

Abstract

The invention discloses a green accurate preserving and fresh-keeping method for blueberries and an application thereof. The method comprises the following steps: spraying treatment is carried out forblueberries with a before-harvest biological antistaling agent, fruits are nondestructively graded according to sizes, the fruits are harvested and placed in a precooling refrigerator in 3-5 hours, rapid precooling is carried out for 6-10 hours, precooling is carried out for 4-8 hours at 0+ / -0.5 DEG C, and then an antifog fresh-keeping bag whose thickness is 20-35[mu]m for slightly controlled atmosphere is used as an outer lining of a small basket for sealing; low temperature domestication is carried out at -1.6 to -1.2 DEG C for 6-8 hours, storage is carried out for 60-70 days with accuratetemperature control at -0.8 to -0.5 DEG C or -0.5 to -0.2 DEG C, the temperature of the refrigerator is adjusted to 0-0.5 DEG C, awaking time is 48-72 hours, awaking is carried out again at 10+ / -0.5 DEG C for 24-36 hours, external packing is removed in order to carry out high-concentration 1-MCP fumigating treatment, and commercial package of blueberries is carried out. Combination of technology and technological parameter is used, in order to substantially maintain original quality of blueberries and improve quality of blueberries.

Description

technical field [0001] The present invention relates to a pre-harvest and post-harvest preservation technology for blueberries, in particular to precise pre-harvest biological preservative treatment, precise specification grading, precise temperature storage technology (stage cooling-low temperature domestication-precise temperature control-stage recovery), precise high Concentration 1-MCP antiseptic treatment of blueberry prenatal and postharvest antiseptic green preservation method. Background technique [0002] Blueberry, also known as lingonberry, is also called blueberry because it is a small dark blue berry fruit, belonging to the rhododendron family ( Ericaceae ) Vaccinium ( Vaccinium ) plant, the fruit is nearly round, the flesh is delicate, the flavor is unique, the nutrition is rich, and the antioxidant activity is high. However, because blueberries are not easy to store, the development of the blueberry industry is limited, so seeking the best fresh-keeping tec...
