Embodiment 1

[0024] 1. Cold storage disinfection

[0025] Mix copper sulfate, quicklime, and water in a mass ratio of 1:1:50, brush the roof, wall and floor of the cold storage, and dry; scrub the plastic fruit basket with a bleach solution with a mass fraction of 0.5%, and dry; Use a disinfectant with a mass ratio of formaldehyde to potassium permanganate of 5:1 at 5 g / m 3 The amount of fumigation cold storage for 24 hours.

[0026] 2. Making preservatives

[0027] Soak the vermiculite with a particle size of 3-4mm in an aqueous solution of potassium permanganate with a mass fraction of 5% for 2 hours, drain it and dry it in the shade, put it into a polyethylene plastic bag with a thickness of 0.03mm, 100g per bag, and seal it .

[0028] 3. Select Shaguo fruit

[0029] Select Shaguo, a late-maturing variety with normal fruit development, fully colored fruit surface, full of luster, no pests and diseases, and no mechanical damage. The soluble solid content of the pulp is required to be...

Embodiment 2

[0039] In the storage and fresh-keeping step 5 of embodiment 1, after precooling, the fruit basket that sand fruit is housed is moved into the air-conditioning cold storage for stacking, and the fruit basket is 15cm apart from the side wall, and 50cm apart from the top of the storehouse, and the distance between the fruit baskets is 5cm. At the same time, put the antistaling agent in an amount of 2% of the storage quality of each basket of sand fruit, and pierce 10 needle holes in each bag of preservative. After the sand fruit is put into storage, fill O 2 , CO 2 , N 2 The mixed gas is charged to balance with the natural atmospheric pressure, and the gas index of the mixed gas is: O 2 The volume fraction is 2%, CO 2 The volume fraction is 1%, N 2 The volume fraction is 97%, and it is stored under the conditions of 0-1°C and relative humidity of 90%-95%. During the storage period, ozone is filled into the cold storage every 30 days until the ozone concentration reaches 12mg / ...

Embodiment 3

[0041] In the storage and fresh-keeping step 5 of embodiment 1, after precooling, the fruit basket that sand fruit is housed is moved into the air-conditioning cold storage for stacking, and the fruit basket is 15cm apart from the side wall, and 50cm apart from the top of the storehouse, and the distance between the fruit baskets is 5cm. At the same time, put the antistaling agent in an amount of 4% of the storage quality of each basket of sago, and pierce 10 needle holes in each bag of preservative. After the sago is put into storage, fill O 2 , CO 2 , N 2 The mixed gas is charged to balance with the natural atmospheric pressure, and the gas index of the mixed gas is: O 2 The volume fraction is 4%, CO 2 The volume fraction is 3%, N 2 The volume fraction is 93%, and it is stored at 2-3°C and the relative humidity is 90%-95%. During the storage period, ozone is poured into the cold storage every 30 days until the ozone concentration reaches 16mg / m 3 Afterwards, keep the war...

Abstract

The invention discloses a storage method of Chinese pearleaved crabapples. Under a low-temperature condition, through adding a preservative, regulating the gas composition of a storage environment and combining with intermittent ozone treatment, the Chinese pearleaved crabapples are stored, thus harmful gases such as ethylene released in a storage period of the Chinese pearleaved crabapples can be effectively removed, the fruit respiration intensity of the Chinese pearleaved crabapples is reduced, the material consumption is reduced, the tissue aging is delayed, the bacterium growth is inhibited, the Chinese pearleaved crabapples are prevented from being softened and rotten, the good quality is maintained, and the storage period is prolonged. By adopting the storage method, the Chinese pearleaved crabapples are stored for over 150 days, the Chinese pearleaved crabapples are good in quality after the storage is ended, and the rotting rate is lower than 5 percent. The storage method is simple to operate, stable in technology, long in storage period, free of chemical pollution, good in preservation effect and remarkable in economic benefit, and can be popularized and used during production.

Description

technical field [0001] The invention belongs to the technical field of general preservation of foods or foodstuffs, and in particular relates to a method for storing sand fruits under low temperature conditions by using preservatives, controlled atmosphere and intermittent ozone treatment. Background technique [0002] Shaguo (scientific name: Malus asiatica), also known as Huahong, Ringo, Wenlinguo, Lianzhuguo, is a small deciduous tree of the genus Malus in the Rosaceae family. The fruit is ripe in autumn, oblate, 4-5cm in diameter, yellow or red. It is widely distributed in the Yellow River and Yangtze River basins in mainland China. It grows in areas with an altitude of 50 meters to 1300 meters. It often grows on hillsides, flats and valley terraces. It tastes like apples when eaten raw. There are many varieties. It is a unique plant in China. Shaguo fruit is bright in color, fragrant, sweet and sour, and unique in flavor. It is rich in carbohydrates, organic acids, cru...
