Problems solved by technology

However, due to the unique biological characteristics of tangerines, it is difficult to keep fresh compared with other citrus fruits, and the post-harvest loss is quite serious. The annual loss is more than hundreds of millions of yuan, which seriously restricts the development of tangerine industry.
[0003] Common problems in the storage, transportation and sales of tangerines include: leaf shedding, fruit rot, quality decline, short shelf life, etc.
1-MCP has a great influence on the ripening and senescence of fruits with climacteric types, such as apples, pears, bananas, avocados, kiwi, plums and apricots, and has a good fresh-keeping effect and broad application prospects; Such as citrus, lychee, fresh dates, cherries, etc., the preservation effect is not great

Embodiment 1

[0025] Shatangju fruit is harvested when it is ripe at 8, and 2 leaves are left on the fruit base. Fruits without pests and mechanical injuries are selected. The Shatangju fruit is soaked with 750 ppm carbendazim for 30 seconds. After drying, the fruit is pressed into 10 kg Put it into a low-density polyethylene fresh-keeping bag with a size of 80×70 cm and a thickness of 0.03 mm, place the fresh-keeping bag in a plastic basket with a size of 45×33×21 cm, and weigh 0.05 g of 1-methylcyclopropene preparation powder (Ethybloc TM ), put it into a small plastic container, put the small plastic container in a fresh-keeping bag, add 1 ml of water to dissolve it, the final concentration of 1-MCP released in the bag is about 5 ppm, immediately tie the mouth of the fresh-keeping bag tightly with a rubber band, and place Treat at 20°C for 24 hours, then remove the closed state, wrap the mouth of the fresh-keeping bag with a rubber band for 1 circle, and store at 20°C. After 22 days of s...

Embodiment 2

[0028] The fruit of Shatangju is harvested at 8 mature, with 2 leaves left on the fruit pedicle, and the fruit without pests and mechanical damage is selected. The fruit of Shatangju is soaked in 1000 ppm Teketor for 30 seconds, and after drying, the fruit is pressed into 10 kg Put it into a low-density polyethylene fresh-keeping bag with a size of 80×70 cm and a thickness of 0.03 mm, place the fresh-keeping bag in a plastic basket with a size of 45×33×21 cm, and weigh 0.005g of 1-methylcyclopropene preparation powder (Ethybloc TM ), put it into a small plastic container, put the small plastic container in a fresh-keeping bag, add 1 ml of water to dissolve it, and the final concentration of 1-MCP released in the bag is about 0.5 ppm, immediately tie the mouth of the fresh-keeping bag tightly with a rubber band, and place Treat at 20°C for 36 hours, then remove the closed state, wrap the mouth of the fresh-keeping bag with a rubber band for 1 circle, and store at 20°C. After 22...

Embodiment 3

[0030] The fruit of Shatangju is harvested at 8 mature, and 2 leaves are left on the fruit base. Fruits without pests and mechanical injuries are selected, and the fruit of Shatangju is soaked in 1000 ppm Shibaoke for 30 seconds. After drying, the fruit is pressed into 7.5 kg Put it into a low-density polyethylene fresh-keeping bag with a size of 60×50 cm and a thickness of 0.02 mm, place the fresh-keeping bag in a plastic basket with a size of 43×32×13 cm, and weigh 0.1 g of 1-methylcyclopropene preparation powder (Ethybloc TM ), put it into a small plastic container, put the small plastic container in a fresh-keeping bag, add 1 ml of water to dissolve it, the final concentration of 1-MCP released in the bag is about 20 ppm, immediately tie the mouth of the fresh-keeping bag tightly with a rubber band, and place Treat at 15°C for 12 hours, then remove the closed state, wrap the mouth of the fresh-keeping bag with a rubber band for 1 circle, and store at 15°C. After 22 days of...

Abstract

The invention relates to a method for fresh-keeping of sugar citrus with leaves, which is used for treating the fruits of the sugar citrus with 0.5-20 ppm of 1-methylcyclopropene (1-MCP) as an ethylene action inhibitor for certain time so as to efficiently slow down the aging (etiolating, browning or rotting) and falling off of the leaves during post-harvest storage, greatly enhance the fresh-keeping effect of sugar citrus with leaves and maintain quality of the fruits. The method disclosed by the invention is adopted to keep the sugar citrus with leaves fresh; and after storage at low-temperature of 4-8 DEG C for 50 days, or at room-temperature of 15-25 DEG C for 15-30 days, the leaves of sugar citrus are still green, the falling-off rate of the leaves is under 5% and the original quality and marketability of the fruits are still kept.

Description

technical field [0001] The invention relates to fruit storage and fresh-keeping technology, in particular to a method capable of keeping shatangju with leaves. Background technique [0002] Shatangju is a characteristic fruit in Guangdong, mainly produced in Zhaoqing, Yunfu and other places. Because the peel of Shatangju is bright red and beautiful, the skin is thin and easy to peel, it is sweet and sour, and there are few seeds and no residue. In addition, the harvest season coincides with the Spring Festival. Therefore, it is very popular with consumers and is quite competitive in the domestic and foreign fruit markets. However, due to the unique biological characteristics of tangerines, it is difficult to keep fresh compared with other citrus fruits, and the post-harvest loss is quite serious. The annual loss is more than hundreds of millions of yuan, which seriously restricts the development of tangerine industry. [0003] The common problems in the storage, transportat...
