Embodiment Construction

[0017] Below in conjunction with test the present invention is further described:

[0018] 1. Preparation of electrolyzed water: prepare the acidic electrolyzed water stock solution, dilute it with tap water into acidic electrolyzed water with available chlorine concentration of 10mg / L, 20mg / L, 30mg / L, 40mg / L, 50mg / L, 60mg / L, and Deionized water is used as a contrast, and Table 1 is the physical and chemical parameters of acidic electrolyzed water and deionized water used in this test;

[0019] Table 1 Physical and chemical parameters of acidic electrolyzed water and deionized water

[0020]

[0021] 2. Grouping loofahs: Pick loofahs with the same shape, size, and color in the early morning, clean, free from pests and diseases, and without mechanical damage, or pick loofahs at other times to dissipate the heat in the field;

[0022] 3. Treatment of loofahs with electrolyzed water with different available chlorine concentrations: Divide the picked loofahs into 7 groups on a...

Abstract

The invention relates to a method for fresh keeping of dishcloth gourds by utilizing acidic electrolyzed water. The method comprises the following steps of (1) preparing an acidic electrolyzed water stock solution, and diluting the prepared acidic electrolyzed water stock solution to obtain acidic electrolyzed water (liquid A) of which the available chlorine concentration is 50mg / L-60mg / L; (2) picking commercial maturity dishcloth gourds which have consistent shapes, sizes and color, and are clean, free from diseases and insect pests, and free from mechanical injury, or picking dishcloth gourds at other times, and then dispersing field heat; (3) putting the picked dishcloth gourds in the liquid A for soaking for 5 minutes, and drying the soaked dishcloth gourds indoors through natural ventilation; and (4) transferring the dried dishcloth gourds into polyethylene film freshness protection packages of which the thickness is 0.03mm, performing non-ironing sealing packaging, and then putting the packaged freshness protection packages in dark conditions of 13 DEG C for storage. After the dishcloth gourds are treated by the method, the rate of weight loss and the brown stain degree can be reduced, the generation of diseases and decomposition of the dishcloth gourds can be avoided, and a good storage and fresh keeping effect can be achieved. The method has the characteristics of being simple to operate, notable in effect and the like.

Description

technical field [0001] The invention relates to the application of electrolyzed water in vegetable preservation, in particular to a method of using slightly acidic electrolyzed water to preserve loofah, using electrolyzed water with different concentrations of available chlorine to treat post-harvest loofah, and to screen out the loofah which can significantly reduce the weight loss rate and browning of loofah The effective chlorine concentration of electrolyzed water to prevent loofah rot and storage diseases, prolong the shelf life of loofah, and maintain the quality of postharvest loofah. Background technique [0002] Loofah belongs to melon vegetables and is the main vegetable variety in summer and autumn in my country. After harvesting, it is not resistant to storage, its quality deteriorates rapidly, and its water loss is serious. Along with the yellowing of the peel, wilting, and fibrosis of the pulp, it loses its original commodity value. , shorter shelf life. Low te...
