Problems solved by technology

At present, there are very few studies on the storage and preservation of okra tender pods. Therefore, the development of effective storage and preservation technology will solve the problem of short shelf life in the transportation, sales, storage and processing of okra tender pods, so as to meet the growing demand at home and abroad. The need for fresh sales is very important

Embodiment 1

[0021] Select tender okra pods with uniform size, consistent maturity, no pests and mechanical injuries, and after pre-cooling in a cold storage at 2°C for 4 hours, put 10 kg of tender okra pods into a low-pot with a size of 80 × 70 cm and a thickness of 0.03 mm. Density polyethylene fresh-keeping bag, put the fresh-keeping bag in a 45×33×21 cm plastic basket, weigh 0.05g 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 Store at 7°C. During the storage process, the fresh-keeping bag is always in a closed state. After 30 days, the tender pods of okra had no rot, no browning, the pericarp remained green, and the fruit still maintained the hardness when harvested, but without lignification. ...

Embodiment 2

[0024] Select tender okra pods with uniform size, consistent maturity, no pests and mechanical injuries, and pre-cool them in a cold storage at 4°C. After pre-cooling for 8 hours, pack okra tender pods into 10 kg with a size of 80×70 cm and a thickness of 0.015 cm. mm low-density polyethylene fresh-keeping bag, put the fresh-keeping bag in a 45×33×21 cm plastic basket, weigh 0.1g 1-methylcyclopropene preparation powder (Ethybloc TM ), put it into a small plastic container, put the small plastic container in a fresh-keeping bag, add 0.5 ml of water to dissolve it, the final concentration of 1-MCP released in the bag is about 10 ppm, immediately tie the mouth of the fresh-keeping bag tightly with a rubber band, and place Store at 8°C. During the storage process, the fresh-keeping bag is always in a closed state. After 30 days, the tender pods of okra had no rot, no browning, the pericarp remained green, and the fruit still maintained the hardness when harvested, but without lign...

Embodiment 3

[0027] Select tender okra pods with uniform size, consistent maturity, no pests and mechanical injuries, and pre-cool them in a cold storage at 3°C. After pre-cooling for 6 hours, pack okra tender pods into 10 kg with a size of 80×70 cm and a thickness of 0.03 mm low-density polyethylene fresh-keeping bag, put the fresh-keeping bag in a 45×33×21 cm plastic basket, weigh 0.005g 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 Store at 6°C. During the storage process, the fresh-keeping bag is always in a closed state. After 30 days, the good fruit rate of okra tender pods is more than 95%, the browning rate is less than 4%, and the fruit can basically keep green and firm when harveste...

Abstract

The invention discloses a storage and fresh-keeping method of a hibiscus esulentus L. tender pod. The storage and fresh-keeping method comprises the following steps of 1, selecting hibiscus esulentus L. tender pods which do not have mechanical damage and insect diseases, and are harvested in an appropriate stage, 2, pre-cooling the selected hibiscus esulentus L. tender pods, and 3, putting the pre-cooled hibiscus esulentus L. tender pods into fresh-keeping bags, treating the pre-cooled hibiscus esulentus L. tender pods by 0.5 to 20ppm of 1-methylcyclopropene, tying up mouths of the fresh-keeping bags instantly, and storing the fresh-keeping bags at a temperature of 6 to 8 DEG C, wherein in storage, the fresh-keeping bags are sealed for more than 12 hours. On the basis of a low temperatureand packaging, the storage and fresh-keeping method combines with hibiscus esulentus L. tender pod biological characteristics, adopts an ethylene effect inhibitor of 1-methylcyclopropene having an appropriate concentration, can effectively delay hibiscus esulentus L. tender pod aging symptoms of browning, decaying and lignification, can reduce decaying, and can prevent cold injuries. Fresh hibiscus esulentus L. tender pods stored by the storage and fresh-keeping method still retain original quality after being stored for more than a month.

Description

Technical field [0001] The present invention involves the preservation technology of fruits and vegetables, and specially involves a method of storing fresh okra and tender pods. Background technique [0002] Yellow Okra is Malvaceae, ABelmoschus Medic, also known as sheep bean, okra, coffee yellow sunflower.Native to Africa, is now widely cultivated in tropical and subtropical regions, with the most southern United States.The protein, total sugar, and polysaccharides in the yellow okra and tender pods are rich in nutritional health value.In addition, the caffeine content in yellow okra seeds is about 1%, which can be used as a substitute for coffee beans.According to reports, Yellow Okra has functions such as anti -fatigue, stomach -keeping liver, reducing lung damage, improving the body's immunity, anti -cancer, diuretic, enhancing vascular dilation, and protecting the heart.It is one of the most popular vegetables in developed countries such as North America and Europe, and it...
