Embodiment 1

[0061] A method for processing clean vegetables, characterized in that it comprises the following steps:

[0062] (1) Harvesting, timely harvesting of vegetables that meet the quality requirements of harvesting, and strictly controlling the quality of vegetables;

[0063] (2) Vacuum pre-cooling. Spray the pretreatment liquid on the surface of the harvested vegetables, then place them in a vacuum chamber, turn on the vacuum pump and refrigeration device, and when the temperature in the vacuum chamber drops to 3°C, turn off the vacuum pump and refrigeration device and keep it for 40 minutes. Pre-cooled vegetables are obtained; wherein the pre-treatment liquid is 2wt% calcium chloride aqueous solution, and the spraying amount of the pre-treatment liquid is 5% of the mass of the harvested vegetables;

[0064] (3) trimming, trimming the precooled vegetables, removing yellow leaves, disease spots, and vegetables that do not meet the requirements, so that the edible part reaches more...

Embodiment 2

[0078] It is basically the same as Embodiment 1, the difference is:

[0079] The preservation solution is composed of the following raw materials in parts by weight: 6% by weight of plant extract, 3% by weight of film-forming agent, 1% by weight of emulsifier, and 90% by weight of deionized water. The preparation method of the preservative solution is as follows: mix the components, stir at 25° C. and 1000 rpm for 5 hours, and then ultrasonically treat for 30 minutes to obtain the preservative solution, wherein the ultrasonic frequency is 40KHz and the ultrasonic power is 500W.

[0080] The plant extract is spinach seed extract.

[0081] The preparation method of the spinach seed extract is as follows: crush the spinach seeds and pass through a 60-mesh sieve, then use 70wt% ethanol to extract 40min at 70°C, an ultrasonic frequency of 40KHz, and an ultrasonic power of 400W according to a solid-liquid ratio of 1g:20mL, and end Suction filtration is then carried out, the filtrat...

Abstract

The invention provides a clean vegetable processing method, which mainly comprises the steps of harvesting, vacuum precooling, trimming, cleaning, cutting, fresh keeping, dehydration, packaging, cold storage and the like; the method is safe and efficient, can effectively remove microorganisms on the surface of the clean vegetable, better prolongs the shelf life of the clean vegetable, and ensures the quality and nutritional value of the clean vegetable to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of clean vegetable processing, in particular to a clean vegetable processing method. Background technique [0002] As one of the indispensable foods in people's daily diet, vegetables can supplement various vitamins and minerals needed by the body. Due to the backwardness of post-harvest processing and circulation system of vegetables in our country, there are serious problems such as post-harvest loss, urban environmental pollution and labor waste. According to statistics, about 30% of vegetables in our country are spoiled and deteriorated during harvesting, storage, processing and transportation every year, and the loss of vegetables is as high as hundreds of millions of tons, which can almost meet the basic nutritional needs of 200 million people. Therefore, how to effectively ensure the quality of vegetables, suppress their dehydration, yellowing and rot speeds in the process of storage, transportation ...
