Embodiment 1

[0057] Embodiment 1: Different ripeness and processing apple quality in 60 days after harvesting

[0058] 1) Harvest apples at the commercial ripening stage of Fuji apples and 12 days after the commercial ripening stage of Fuji apples (late harvesting) to obtain commercial ripening apples and late harvesting apples, and pre-cool after removing diseased and defective fruits;

[0059] 2) Put the above apples into fruit baskets, stack them in a pre-cooling room at 0-1°C, and pre-cool them for 3 days. During the pre-cooling process, some apples will not be treated, and some apples will be treated with 1.0 μL / L 1-methylcyclopropene. The time is 24 hours, and the processing method is that the apples are fumigated with 1-methylcyclopropene in a closed plastic tent in a pre-cooling room.

[0060] 3) After the pre-cooling and processing, the apples are put into storage for refrigeration; the temperature of the refrigerator is -1-1°C, and the humidity is not lower than 90%.

Embodiment 2

[0065] Embodiment 2: different ripeness and processing apple quality in 120 days after harvesting

[0066] 1) Harvest apples at the commercial ripening stage of Fuji apples and 10 days after the commercial ripening stage of Fuji apples (late harvesting) to obtain commercial ripening apples and late harvesting apples, and pre-cool after removing diseased and defective fruits;

[0067] 2) Put the above apples into fruit baskets, loosely stack them in the pre-cooling room at 0-1°C, and pre-cool them for 3 days. During the pre-cooling process, some apples will not be treated, and some apples will be treated with 1.0 μL / L 1-methylcyclopropene. The processing time is 24 hours, and the processing method is that the apples are fumigated with 1-methylcyclopropene in a closed plastic tent in a pre-cooling room.

[0068] 3) After the pre-cooling and treatment, the apples are stored in a refrigerator; the temperature of the refrigerator is -1-1°C, and the humidity is not lower than 90%. ...

Embodiment 3

[0073] Embodiment 3: Different ripeness and processing apple quality in 180 days after harvesting

[0074] 1) Harvest apples at the commercial ripening stage of Fuji apples and 10 days after the commercial ripening stage of Fuji apples (late harvesting) to obtain commercial ripening apples and late harvesting apples, and pre-cool after removing diseased and defective fruits;

[0075] 2) Put the above apples into fruit baskets, stack them in a pre-cooling room at 0-1°C, and pre-cool them for 3 days. During the pre-cooling process, some apples will not be treated, and some apples will be treated with 1.0 μL / L 1-methylcyclopropene. For 24 hours, the processing method is that the apples are fumigated with 1-methylcyclopropene in a closed plastic tent in the pre-cooling room.

[0076] 3) After the pre-cooling and treatment, the apples are stored in a refrigerator; the temperature of the refrigerator is -1-1°C, and the humidity is not lower than 90%.

Abstract

The invention relates to an apple low-temperature segmented storage method, which comprises the following steps: 1) stacking apples in a pre-cooling chamber at the temperature of 0-1 DEG C after beingharvested, pre-cooling the apples for 2-3 days, and adopting 1-methylcyclopropene for processing a part of apples during a pre-cooling process; wherein the remaining apples are only pre-cooled; the apple includes apple harvested at a commercial mature stage of the apple and late harvested apple, and the late harvested apple is the apple harvested 7 to 12 days after the commercial mature period; 2) performing pre-cooling and storage refrigeration of apples; wherein the cold storage temperature is -1 to 1 DEG C, and humidity is not lower than 90%; 3) according to the selling time of the storedapples, dividing an entire storage period into different time periods, and selecting the apples with different harvest maturity and different processed storage at each time period for sales. The method aims at short-term, middle-term and long-term storage of apples, and uses the apples with different maturity and post-harvest treatment methods with different intensities, and at the same time, low-temperature storage is combined to improve food quality during shelf storage of the apples.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of fruits and vegetables, and in particular relates to a low-temperature segmental storage method for apples. Background technique [0002] China is not only a big apple producer, but also a big apple consumer. While our country's economy is developing, the national dining table is also quietly changing. From the original simple food, meat and vegetables, to now fruits have become an indispensable part of people's lives. Apples contain a large amount of vitamins, minerals and trace elements. In addition, apples also contain chemical substances such as polyphenols, triterpenes and phytosterols, which have good anti-tumor, anti-oxidation, liver protection, prevention of cardiovascular and cerebrovascular diseases and enhancement. Memory and other effects, is one of people's favorite fruit. [0003] Apple is a climacteric fruit, and its post-ripening effect can improve the edible quality of t...
