Problems solved by technology

[0003] Due to the large surface area of ​​leaf-eating grass leaves, easy to lose water, and fragile tissues, it is easy to cause mechanical damage after picking, and the breathing intensity is high. During transportation, it is easy to wilt, yellow, rot and other problems, resulting in shortened shelf life. good preservation method

Embodiment 1

[0027] Choose a vegetable leaf leaves that are harvested, no mechanical injury and pests and pests; uniform spraying preservation agents, the preservative contains 0.05% propionic acid, pyropopyneua 30 ppm, adenosine The concentration of triphosphate is 10 ppm. The preparation method of the preservation agent is to add propionic acid, chloropyripateneutin, adenosine triphosphate to water in water, mix well, and mix well. Then the food-treated eaters were dried; the treated eaten herbs were loaded into a polytetrafluoroethylene microporous film having a thickness of 0.03 mm, and the final concentration was 10 ppm 1-A Base cyclic propylene, tighten the bag, stored at 25 ° C. It is carried out for storage preservation of eating leaves by the method of the present invention, and can be stored for 10 days at normal temperature. Compared to the ratio 1, the rot rathe is reduced by 50%, and the yellowing rate is relatively reduced by 85%. image 3 ).

Embodiment 2

[0029] Choose a vegetable leaf leaves that are harvested, no mechanical injury and pests and pests; uniform spraying preservation agents, the preservative contains 0.05% propionic acid, pyropopyneua 30 ppm, adenosine The concentration of triphosphate was 50 ppm. The preparation method of the preservation agent is to add propionic acid, chloropopynen uretenena, adenosine triphosphate to the water according to its content, and mix well and uniformly prepare. Then the food-treated eaters were dried; the treated eaten herbs were loaded into a polytetrafluoroethylene microporous film having a thickness of 0.03 mm, and the final concentration was 10 ppm 1-A Base cyclic propylene, tighten the bag, stored at 4 ° C. It is carried out for 60 days of storage for 60 days by the method of the present invention, and after 60 days of low temperature conditions, the rot rat rate is reduced by 80%, and the yellowing rate of the blade is relatively reduced by 85%. Figure 4 ).

Embodiment 3

[0031] Choose a vegetable leaf leaves that are harvested, no mechanical damage and pest injury; the surface of the surface of the leaf is sprayed, the preservation agent contains 0.01% mass propionic acid, a chloropyrida 50 ppm, adenosine The concentration of triphosphate is 100 ppm, the preparation method of the preservation agent is to add propionic acid, chloropopynen uretena, adenosine triphosphate to water, mix well, and mix well. Then the freshly treated eating leaf is dried; the treatment of eaten leaves into a polytetrafluoroethylene microporous film having a thickness of 0.03 mm in the locking water, and the final concentration is 30 ppm 1-A Base cyclic propylene, tighten the bag, stored at 4 ° C. With the present invention, it was stored in a storage preservation of eating, and after 60 days of low temperature conditions, the rot ratio was reduced by 95% compared to the ratio 1, and the yellowing rate of the blade was relatively reduced by 95%.

Abstract

The invention discloses a fresh-keeping method of rumex hanus. The method comprises the following steps: a, selecting rumex hanus leaves without mechanical damage and pest and disease damage; b, evenly spraying a preservative to the surfaces of the rumex hanus leaves, wherein the preservative is prepared from propionic acid with the concentration of 0.01%-0.5% by mass, forchlorfenuron with the concentration of 10-50 ppm and adenosine triphosphate with the concentration of 10-100 ppm; and c, airing the rumex hanus subjected to preservation treatment, putting the rumex hanus into a water-locking and breathable functional packaging bag, putting 1-methylcyclopropene into the packaging bag until the final concentration is 1-30 ppm, tightening the packaging bag, and storing the rumex hanus. When the rumex hanus is stored and preserved by adopting the method, after the rumex hanus is stored for 60 days under a low-temperature condition, the rotting rate is reduced by 95%, and the leaf yellowing rate is relatively reduced by 95%; and the rumex hanus can be stored for 10 days at normal temperature, the rotting rate is reduced by 50%, and the yellowing rate is relatively reduced by 85%.

Description

Technical field: [0001] The present invention belongs to the field of preservation, and specifically involves a method of eating leaf. Background technique: [0002] Rumexpatientia L. × rumex.tianschiicusa.los, also known as "protein" for perennial plants, the protein content of up to 4.5%, is a Chinese cabbage, amaranth, spinach, oil in protein content 3.0, 1.6 1.73 and 2.5 times, comparable to the soy protein content, is a new source of plant protein; rich in mineral potassium, content of 2805 mg / 100g, is 9.02 times of potassium element content (311.0 mg / kg) in spinach; In addition, eating leaf contains 8 essential amino acids and bioactive substances superoxide dismutase, high nutritional value, and has the potential to become new food raw materials. [0003] Because of the large surface area of ​​the eating leaf, it is easy to lose water, the organization is fragile, and it is easy to cause mechanical damage. The breathing intensity is very large, the transportation proce...
