Problems solved by technology

However, in the process of use, it has been accompanied by the following problems: If SO 2 Insufficient dosage, poor anti-corrosion effect, and excessive SO 2 The treatment will cause bleaching damage to the grapes
At present, the research on natamycin at home and abroad is still in its infancy, mainly focusing on the simple application and production of natamycin. There is no systematic report on the theory and application of natamycin in fresh fruits and vegetables.

Embodiment 1

[0016] A method for keeping grapes fresh, comprising the steps of: spraying newly picked ripe grapes without rot, shattering, and mechanical damage with 0.1g / L natamycin aqueous solution, and the grapes are mixed with natamycin The ratio of mycin aqueous solution is 500g: 2mL, (the control group is sprayed with 2mL of water as a control). After spraying, let it dry naturally at room temperature, pack it in a thin polyethylene bag, and store it at 0°C±1°C for 70 sky. During the storage process, the decay rate, shattering rate, fruit firmness, respiration intensity and soluble solid content of grape fruit were measured to evaluate the fruit quality, and the changes of fruit enzyme (PPO enzyme, POD enzyme, PAL enzyme) activity were measured. See figure 1 , 2, 3.

Embodiment 2

[0018] A method for keeping grapes fresh, comprising the steps of: spraying newly picked ripe grapes without rot, shattering, and mechanical damage with a 0.5g / L natamycin aqueous solution, the grapes being mixed with natamycin The ratio of mycin aqueous solution is 500g: 2mL, (the control group is sprayed with 2mL water as a control) after spraying, let it dry naturally at room temperature, pack it in a thin polyethylene bag, and store it at 0°C±1°C for 1 day . During the storage process, the decay rate, shattering rate, fruit firmness, respiration intensity and soluble solid content of grape fruit were measured to evaluate the fruit quality, and the changes of fruit enzyme (PPO enzyme, POD enzyme, PAL enzyme) activity were measured. See figure 1 , 2, 3.

Embodiment 3

[0020] A method for keeping grapes fresh, comprising the steps of: spraying newly picked ripe grapes without rot, shattering, and mechanical damage with 0.1g / L natamycin aqueous solution, and the grapes are mixed with natamycin The ratio of mycin aqueous solution is 500g: 3mL. After spray treatment, let it dry naturally at room temperature, pack it in a thin polyethylene bag, and store it at 0°C±1°C for 70 days.

Abstract

The invention discloses a method for preserving grapes. The method is characterized by comprising the following steps: atomizing newly picked ripe grapes without rot, shattering or mechanical damage through 0.1g / L-0.5g / L of a natamycin water solution, wherein the ratio of the grapes to the natamycin water solution is 500:(1-3ml); and naturally airing at normal temperature after atomization treatment, packaging with a polyethylene packaging bag, and storing under the condition of 0DEG C+ / -1DEG C. Through the systematic evaluation analysis on the storage quality, rot condition and physiological change of the grapes, the quality of the grapes treated by natamycin is better than that of the grapes in the control group at low temperature, proving that the grapes can be effectively preserved by adopting the method; compared with a traditional grape preservative, the method for preserving grapes has the advantages that the damage and usage amount of SO2 can be decreased, and the preservation safety of the grapes can be improved. The storage period of the grapes can be prolonged to 65-70days by adopting the method.

Description

technical field [0001] The invention belongs to the field of fresh-keeping of fruits and vegetables, and relates to a method for keeping grapes fresh. Background technique [0002] Due to the characteristics of high water content and thin skin of grapes, grapes are easy to damage and rot, and the storage period after harvest is short. Therefore, research on grape preservation technology during storage and transportation is a hotspot. At present, domestic and foreign grape preservation methods include cellar storage, low temperature, SO 2 fumigated or with SO 2 Fumigation methods such as gas generating agent, sec-butylamine and its derivatives, among which SO 2 The gas has an ideal antiseptic and fresh-keeping effect on grapes. It is an effective fungal inhibitor that can kill spores and prevent the growth of mold on the surface of grapes. It has become a grape preservative commonly used at present. However, in the process of use, it has been accompanied by the following...
