Problems solved by technology

Fresh blueberries are the main product form of blueberries produced in various countries in the world, and the consumption of fresh blueberries is still growing in a good manner; however, blueberries are still a living organism after harvesting, which can maintain stable aerobic respiration and consume continuously. Its own nutrients produce carbon dioxide and water, so it is not easy to store and keep fresh
[0003] At present, the distribution methods of fresh blueberries in my country mainly include bulk, plastic baskets and perforated PET boxes. These methods directly expose or semi-expose them to the external environment, which can easily cause water loss and infection by microorganisms. , cause mechanical damage, so that the fully mature blueberry fruit will appear dehydration, wilting, softening, rot and other symptoms when placed at room temperature (20°C) for 2 to 4 days, and the shelf life is quite short
At the same time, blueberries are often washed with clean water, low-concentration salt water or ozone water before eating. This treatment method cannot completely solve the problem of pathogenic bacteria and pesticide residues, and cannot meet people's requirements for food hygiene and safety.

Embodiment 1

[0042] Embodiment 1 of the present invention discloses a combined processing method for shelf preservation of blueberry fruit, which specifically includes the following steps:

[0043] (1) Pre-harvest treatment: First weigh 31.0g of β-aminobutyric acid with a purity greater than 98%, fully dissolve it in water, and then dissolve it in a 30L pressure watering can, then add 15g of Tween-80, mix well Configured as 10mmol L -1 β-aminobutyric acid solution (containing 0.05% Tween-80); 7 days before harvest, when the skin of blueberry fruit has just changed from red to purple, spray β-aminobutyric acid solution evenly and repeatedly on the skin of blueberry fruit, One acre of land can be sprayed per bucket of solution.

[0044] (2) Harvesting and fumigation treatment: 7 days after spraying, the surface color of the blueberries all turns dark purple, and the blueberries are basically mature. Wear gloves or finger cots as required, pick them lightly, avoid mechanical damage, and keep...

Embodiment 2

[0049] Embodiment 2 of the present invention discloses a combined processing method for shelf preservation of blueberry fruit, which specifically includes the following steps:

[0050] (1) Pre-harvest treatment: First weigh 31.0g of β-aminobutyric acid with a purity greater than 98%, fully dissolve it in water, and then dissolve it in a 30L pressure watering can, then add 15g of Tween-80, mix well Configured as 10mmol L -1 β-aminobutyric acid solution (containing 0.05% Tween-80); 7 days before harvest, when the skin of blueberry fruit has just changed from red to purple, spray β-aminobutyric acid solution evenly and repeatedly on the skin of blueberry fruit, One acre of land can be sprayed per bucket of solution.

[0051] (2) Harvesting and fumigation treatment: 7 days after spraying, the surface color of the blueberries all turns dark purple, and the blueberries are basically mature. Wear gloves or finger cots as required, pick them lightly, avoid mechanical damage, and keep...

Embodiment 3

[0056] Embodiment 3 of the present invention discloses a combined processing method for shelf preservation of blueberry fruit, which specifically includes the following steps:

[0057] (1) Pre-harvest treatment: first weigh 30.94g of β-aminobutyric acid with a purity greater than 98%, fully dissolve it in 20L of water, and configure it into 15mmol L -1 β-aminobutyric acid solution, 1 bucket per 20L solution; 7 days before harvest, when the skin of blueberry fruit has just changed from red to purple, spray β-aminobutyric acid solution evenly and repeatedly on the skin of blueberry fruit, 1 barrel Can spray 1 mu of land.

[0058] (2) Harvesting and fumigation treatment: 7 days after spraying, the surface color of the blueberries all turns dark purple, and the blueberries are basically mature. Wear gloves or finger cots as required, pick them lightly, avoid mechanical damage, and keep the fruit powder intact. Harvest Blueberry fruits of the same variety, same size, 9-10 ripe; th...

Abstract

The invention discloses a shelf fresh-keeping combined treatment method for semen trigonellae fruits. Beta-aminobutyric acid spray coating before harvesting and S-nitrosoglutathione fumigation treatment after harvesting are carried out, and enclosing packaging technology with certain air permeability and gamma irradiation technology are combined to realize the purpose, so that the shelf life of semen trigonellae fruits at room temperature or 4-5DEG C can be significantly prolonged, and the semen trigonellae fruits also can maintain good hardness, flavor and nutritional quality.

Description

technical field [0001] The invention relates to the technical field of storage and preservation of agricultural products, and more specifically relates to a combined method for shelf preservation of blueberry fruit. Background technique [0002] Blueberry (Semen trigonellae), also known as lingonberry, blueberry, is a plant of the genus Vaccimium spp. in the Ericaceae family (Ericaceae), a perennial deciduous or evergreen shrub fruit tree, with beautiful fruit color and delicate and juicy pulp , Sweet and sour. Blueberry fruit contains nutrients such as protein, lipids, and carbohydrates. It is also rich in vitamins, mineral elements such as zinc, iron, and manganese, and is also rich in various health-care functional ingredients; Protect eyesight, prevent cardiovascular disease, fight cancer, strengthen brain, etc. Fresh blueberries are the main product form of blueberries produced in various countries in the world, and the consumption of fresh blueberries is still growin...
