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] Select leaf-eating grass leaves harvested on sunny days without mechanical damage and pests; spray preservative evenly on the surface of the leaf-eating grass, and the preservative contains 0.05% propionic acid, 30ppm forchlorfenuron, adenosine The concentration of triphosphoric acid is 10ppm. The preparation method of the antistaling agent is to add propionic acid, forchlorfenuron and adenosine triphosphate into water according to their contents, and mix uniformly to prepare the antistaling agent. Then dry the leaf-eating grass after fresh-keeping treatment; put the treated leaf-eating grass into a polytetrafluoroethylene microporous film bag with a thickness of 0.03mm to lock water and ventilate, and put it into a final concentration of 10ppm 1-methanone at the same time. One pack of cyclopropene, tightly packed and stored at 25°C. Adopt the method of the present invention to carry out storage and fresh-keeping to leaf-eating grass, can store at normal temperature for...

Embodiment 2

[0029] Select leaf-eating grass leaves harvested on sunny days without mechanical damage and pests; spray preservative evenly on the surface of the leaf-eating grass, and the preservative contains 0.05% propionic acid, 30ppm forchlorfenuron, adenosine The concentration of triphosphoric acid was 50 ppm. The preservative is prepared by adding propionic acid, forchlorfenuron and adenosine triphosphate into water according to their contents, and mixing uniformly to prepare the preservative. Then dry the leaf-eating grass after fresh-keeping treatment; put the treated leaf-eating grass into a polytetrafluoroethylene microporous film bag with a thickness of 0.03mm to lock water and ventilate, and put it into a final concentration of 10ppm 1-methanone at the same time. One package of cyclopropene, tightly packed and stored at 4°C. Adopt the method of the present invention to carry out storage and fresh-keeping to leaf-eating grass, store under low temperature condition after 60 days...

Embodiment 3

[0031] Select leaf-eating grass leaves harvested in sunny days without mechanical damage and pests; spray preservative evenly on the surface of the leaf-eating grass, and the preservative contains 0.01% propionic acid, forchlorfenuron 50ppm, adenosine The concentration of triphosphoric acid is 100ppm. The preparation method of the antistaling agent is to add propionic acid, forchlorfenuron and adenosine triphosphate into water according to their contents, and mix uniformly to prepare the antistaling agent. Then dry the leaf-eating grass after fresh-keeping treatment; put the treated leaf-eating grass into a water-locking and breathable polytetrafluoroethylene microporous film bag with a thickness of 0.03mm, and put it into a final concentration of 30ppm 1-formazan at the same time. One package of cyclopropene, tightly packed and stored at 4°C. Using the method of the present invention to store and keep fresh the leaf-eating grass, after storing at low temperature for 60 days, ...

Abstract

The invention discloses a fresh-keeping method for leaf-eating grass. a, select leaf-eating grass blades without mechanical damage and damage by diseases and insect pests; b, spray antistaling agent evenly on the surface of leaf-eating grass blades, and described antistaling agent contains propionic acid, and its concentration is 0.01%-0.5% by mass; Chlorine Phenylfenuron, its concentration is 10-50ppm; Adenosine triphosphate, its concentration is 10-100ppm; c, dry the leaf-eating grass after fresh-keeping treatment again, put into the function packing bag of water-locking breathable, put again Add 1-methylcyclopropene so that the final concentration is 1-30ppm, tie up the packaging bag, and store. The method of the present invention is used to store and keep the leaf-eating grass fresh. After storage at low temperature for 60 days, the rot rate is reduced by 95%, and the yellowing rate of the leaves is relatively reduced by 95%. It can be stored for 10 days at normal temperature, and the rot rate is reduced by 50%. %, the yellowing rate is relatively reduced by 85%.

Description

Technical field: [0001] The invention belongs to the field of fresh-keeping, and in particular relates to a fresh-keeping method for leaf-eating grass. Background technique: [0002] Leaf-eating grass (Rumexpatientia L.×Rumex.tianschanicusA.LOS), also known as "protein grass" is a perennial herb, its protein content can be as high as 4.5%, which is 3.0 and 1.6 of the protein content in Chinese cabbage, amaranth, spinach, and rapeseed. , 1.73 and 2.5 times, equivalent to soybean protein content, is a new source of plant protein; rich in mineral potassium, the content can reach 2805mg / 100g, which is 9.02 times the content of potassium in spinach (311.0mg / kg); In addition, leaf-eating grass contains 8 kinds of essential amino acids and superoxide dismutase, a biologically active substance, which has high nutritional value and has the potential to become a new food raw material. [0003] Due to the large surface area of ​​leaf-eating grass leaves, easy to lose water, and fragil...
