Embodiment 1

[0029] Harvest the blue indigo fruit in small baskets matched with the micro-environment modified atmosphere fresh-keeping box. The maturity of each basket is about 1.0 kg. After 4 hours after harvesting, the place of origin is 0-4 ℃ cold storage for 18 hours, and every two small baskets are put into Put it into the micro-environment modified atmosphere fresh-keeping box of blue indigo fruit, put it in dry ice at the same time, and immediately buckle the cover, and transport it to Tianjin with a 0-4 ℃ cold chain transport vehicle, open the box and put it into a precise temperature-controlled warehouse (program: pre-cooling stage 5 ℃ 4 h, 2 ℃ 4 h, -1 ℃ 8 h, storage stage -0.5 ℃, temperature fluctuation ± 0.3 ℃) fully precooled in the interior and then stacked and stored with the lid on. Divided into the following three treatments: (1) Indigo fruit was put into the micro-environmental atmosphere fresh-keeping box without the air-conditioning element, and no dry ice was added, whi...

Embodiment 2

[0031] Harvest the blue indigo fruit in small baskets matched with the micro-environment modified atmosphere fresh-keeping box. The maturity of each basket is about 1.0 kg. After 4 hours after harvesting, the place of origin is 0-4 ℃ cold storage for 18 hours, and every two small baskets are put into Put 8 g of dry ice in the microenvironment-modified atmosphere fresh-keeping box of blue indigo fruit at the same time, then buckle the lid immediately, and transport it to Tianjin with a 0-4 ℃ cold chain transport vehicle. . Divided into the following two treatments: (1) ordinary cold storage (program: temperature 2 ℃, pre-cooling for 24 h, temperature fluctuation during storage period ± 1.0 ℃); (2) precise temperature control storage (program: pre-cooling stage 5 ℃ 4 h , 2 ℃ 4 h, -1 ℃ 8 h, storage stage -0.5 ℃, temperature fluctuation ±0.3 ℃). pass image 3 It can be seen from the photographs of the appearance of the indigo fruit stored for 60 days that mildew appeared on the ...

example 3

[0034] At present, there are very few researches on the fresh-keeping methods of indigo fruit in the existing research, only the report of edible plastic wrap, and the storage temperature is still at the temperature of 4°C in the family refrigerator. It can be said that indigo fruit is still in a blank stage in the field of fresh-keeping. Due to the concentration of its production areas, the fruit is tender and juicy and cannot be shipped out of the production area. Most of them are processed. With the increase in production, matching fresh-keeping technologies are urgently needed. As can be seen from the comparison of the fresh-keeping effects of the blue-blue fruit in Table 1, the fresh-keeping method adopted in this patent can effectively prolong the storage period of the blue-blue fruit, improve the commerciality of the fruit, and can solve the difficult problems that the blue-blue fruit production areas cannot be transported out and post-harvest fresh-keeping.

Abstract

The invention discloses a fresh-keeping method for prolonging storage period of lonicera caerulea and an application thereof. The method comprises the following steps of picking lonicera caerulea of 8-9 maturity degrees by small baskets matched with a micro-environment air-conditioning fresh-keeping box, wherein each basket contains about 1.0kg in net weight; performing pre-cooling in time in theharvested place after harvesting, putting each two small baskets into one micro-environment air-conditioning fresh-keeping box of lonicera caerulea, meanwhile putting dry ice and covering instantly tobe transported to a destination through a cold-chain transport vehicle; and opening the boxes to be fully pre-cooled in a precise temperature control refrigerator for storage in stacks. The preservation method can avoid the problems of lonicera caerulea fruit cream loss and storage resistance reduction caused by multiple transfers after picking the lonicera caerulea fruits, effectively prolongs the storage period of the lonicera caerulea, fills up the blank of a seamless fresh-keeping method for the lonicera caerulea fruits from picking, transporting and storing.

Description

technical field [0001] The invention belongs to the technical field of storage and preservation of agricultural products, and in particular relates to a blue indigo fruit fresh-keeping mode in which picking, transportation and storage are seamless and integrated with a cold chain throughout the whole process, combined with rapid air conditioning, precise temperature control, and spontaneous air conditioning. A new way to preserve freshness. Background technique [0002] The indigo fruit is a perennial shrub, born in wet grasslands, forests or near mountain streams. It likes a cool and humid climate, has strong cold resistance, and is a wild berry with high utilization value. In my country, it is mainly distributed in the Changbai Mountains of Jilin Province, the eastern part of the Greater Khingan Mountains in Heilongjiang, Inner Mongolia and other places. The indigo fruit has a good taste, moderate sweetness and sourness, thin skin and small seeds, and a high juice yield. ...
