Abstract

The present invention belongs to the technical field of fresh-keeping, and particularly relates to a dehumidifying low-temperature vacuum preservation method for fresh fruits. The method comprises thefollowing steps: putting fresh fruits into a container; carrying out dehumidification on the fresh fruits and the container to obtain dehumidified fresh fruits and container, wherein the temperaturein a low-temperature dehumidification apparatus during low-temperature dehumidification is 5-8 DEG C, the humidity is 50-60%, and the dehumidification time is 2-4h; putting the dehumidified fresh fruits and container into a vacuum bag, and conducting vacuumizing; and putting the vacuumized fresh fruits and container into an environment for preservation, and the temperature of the environment is 1-3 DEG C. The dehumidifying low-temperature vacuum preservation method for fresh fruits firstly subjects the fresh fruits to low-temperature dehumidification and vacuumizing, then puts the fresh fruitsinto a low temperature for cold storage, and controls the temperature, time and humidity of the dehumidification. Fresh fruits treated by the method can be preserved for 17-20 days generally, and canbe preserved as long as 25 days without affecting eating. The vacuum preservation method provided by the invention is simple, easy to operate and convenient to popularize, and the preservation time is long.

Description

technical field [0001] The invention belongs to the technical field of freshness preservation, and in particular relates to a dehumidification and low-temperature vacuum preservation method for fresh fruits. Background technique [0002] With the continuous development of society, people's demand for fresh fruits is increasing, and the output of fruits is increasing. Fruits from one origin may be sold to all parts of the country and even the world. However, it usually takes 3-7 days or longer from fruit picking to packaging and transportation to customers. Before selling them all over the country and even around the world, fruit farmers need to keep these newly picked fruits well to avoid selling them. Broke before going. At present, for the preservation method of fresh fruit, there are following defects: [0003] (1) Using medicines to keep fresh, such as adding preservatives for preservation, can prolong the preservation time, but preservatives are harmful to the human b...
