Problems solved by technology

The planting of grapes will have different moisture and sweetness due to climate conditions and land properties. Therefore, the sweetness and variety of grapes are very different across the country. The most common way to eat grapes at this stage is to prepare raisins, wine and Grape juice, after the grapes are on the market, the quantity of picking at one time is generally relatively large. Therefore, if the picked grapes cannot be sold at one time, they must be stored. However, because grapes belong to berries, they are not resistant to storage among fruits. One of the most popular fruits, dry stems, shattering and rot are the main problems affecting the storage of grapes, which will cause a lot of fresh-keeping loss and generate a lot of waste.

Embodiment 1

[0024] A method for storing and keeping fresh grapes includes the following steps:

[0025] 1) Cold storage storage:

[0026] After harvesting, the orchard is directly bagged, and the fruit is pre-cooled to 0°C in the open, then sulfur dioxide preservative is added, and finally sealed for storage;

[0027] ① Temperature control: The best storage temperature for grapes is between -2°C and 0°C, preferably between -0.5°C and -1.5°C;

[0028] ② Humidity control: Since the grapes are all packed in plastic bags after picking, it is best to control no condensation in the fresh-keeping bag. The humidity should be controlled at 90%-95%, and absorbent paper is generally stored in the bag;

[0029] ③Control of gas composition: the gas in the bag is controlled in CO 2 The concentration is 8%~12%, O 2 <12%, play an obvious spontaneous atmosphere regulation effect;

[0030] 2) Prevention of storage diseases

[0031] ①. Fruit cracking prevention measures:

[0032] b. Strengthen the management of fertiliz...

Abstract

A storage and preservation method for grapes belongs to the technical field of cold storage of fruits. The method comprises storage in cold storage houses, storage disease control and preservatives disease prevention. The method has the following beneficial effects that: storage conditions suitable for grapes are determined, reasonable temperature, humidity and gas components in the storage houses can be guaranteed, the problems during the storage process of grapes such as water loss, aging, yellowing and rotting are solved, the storage time of grapes is prolonged, and the color and the quality of grapes are not destroyed.

Description

Technical field [0001] The invention relates to the technical field of fruit cold storage, in particular to a grape storage and fresh-keeping method. Background technique [0002] The output of grapes accounts for almost a quarter of the world's fruits; its nutritional value is very high and can be made into grape juice, raisins and wine. The cultivation of grapes will have different moisture and sweetness due to climatic conditions and the nature of the land. Therefore, the sweetness and varieties of grapes all over the country are quite different. At this stage, the most edible way to make more grapes is to prepare raisins, wine and Grape juice, the number of grapes picked at one time is generally relatively large after the grapes are on the market. Therefore, if the harvested grapes cannot be sold at one time, they must be stored. However, because the grapes are berries, the fruits are not storage-resistant One of the fruit products, dry stems, shattering and decay are the ma...
