Abstract

The invention discloses a storing and refreshing method of litchis, and relates to the technical field of chemical industry. The storing and refreshing method comprises four technological steps of pretreatment, ultrasonic treatment, ozone water treatment and biological refreshing agent treatment. According to the storing and refreshing method disclosed by the invention, the appearance of the litchis is pretreated before the litchis are processed and treated, so that the rinds of the litchis are cleaned and complete; then through ultrasonic treatment and the ozone water treatment, ultrasonic waves, ozone water and a biological refreshing agent are used for treating the litchis, so that the decaying of the litchis and the brown stains of the rinds of the litchis are slowed down, and the color of the rinds of the litchis is effectively maintained; the storing and refreshing method has a good refreshing effect, is favorable for storage and refreshing of the litchis, and is suitable for production and application.

Description

A kind of method for storing and refreshing of lichee
Technical field
The present invention relates to chemical technology field, be specifically related to a kind of method for storing and refreshing of lichee.
Background technology
Along with the high speed of China's economy finds, living standards of the people rapidly improve, and the demand of common people to fresh fruit increases increasingly.Wherein lichee be a kind of common people than preferable fruit, but the transport of lichee and storage be not easy ensure fresh.
At present, the fresh-keeping method mainly adopting chemical agent leaching fruit and low-temperature transport to combine of China's lychee storage: the fresh-keeping chemical agent of lichee fresh fruit embathes, packs, then low-temperature transport.Cardinal principle be by improving temperature in storage environment, relative humidity, gas componant control transpiration, breathing and disease and pest; Some method also delays lichee aging, brown stain by the generation controlling ethene and rots thus reach fresh-keeping object.Lichee fresh-keeping process is also a lot, be summed up mainly contain several as follows: bubble refrigerator is on the rocks, low temperature (or quick-frozen) storage, air conditioned storage etc.
Ozone, ultrasonic wave are the disinfecting technology in current storage fruit and vegetable, are more and more subject to people's attention.How to utilize new technology to take preservation and freshness lichee, have very high practical significance.
Summary of the invention
Problem to be solved by this invention is to provide a kind of method for storing and refreshing of lichee.
To achieve these goals, the technical scheme that the present invention takes for: the method for storing and refreshing of a kind of lichee provided, comprises the steps:
(1) pretreatment: remove the bad fruits such as fruitlet, sick wormed fruit and mechanical damage by plucking the lichee of returning, clear water dries after cleaning, for subsequent use;
(2) ultrasonic wave process: utilize ultrasonic cleaning agent to the lichee cleaning 10-20min after step (1) process, for subsequent use;
(3) Ozone Water process: utilize ozone generator to the lichee cleaning 5-10min after step (2) process, for subsequent use;
(4) bio-preservative process: utilize the lichee after obtained bio-preservative (macromolecular material) smearing step (3) process, biological preservation film can be formed after dry tack free.
Preferably, Ultrasonic Cleaning unit frequency 28KHz in described step (2); Bottom surface power 1200W, side peak power 1200W, side minimum power 300W.
Preferably, the Ultrasonic Cleaning time in described step (2) is 90s.
Adopt technical scheme of the present invention, before lichee processing process, outward appearance pretreatment is carried out to lichee, make lichee epidermis totally complete, then by the process of using ultrasound ripple and Ozone Water process, ultrasonic wave and Ozone Water and bio-preservative, to after lichee process, slow down rotting and the brown stain of pericarp of lichee, effectively maintain the color of lichee pericarp, there is good fresh-keeping effect, be beneficial to the preservation and freshness of lichee, be very suitable for production application.
Detailed description of the invention
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the present invention further.
Embodiment 1:
(1) pretreatment: remove the bad fruits such as fruitlet, sick wormed fruit and mechanical damage by plucking the lichee of returning, clear water dries after cleaning, for subsequent use;
(2) ultrasonic wave process: utilize ultrasonic cleaning agent to the lichee cleaning 15min after step (1) process, for subsequent use;
(3) Ozone Water process: utilize ozone generator to the lichee cleaning 6min after step (2) process, for subsequent use;
(4) bio-preservative process: utilize the lichee after obtained bio-preservative (macromolecular material) smearing step (3) process, biological preservation film can be formed after dry tack free.
Based on above-mentioned, in the present invention, before lichee processing process, outward appearance pretreatment is carried out to lichee, make lichee epidermis totally complete, then by the process of using ultrasound ripple and Ozone Water process, ultrasonic wave and Ozone Water and bio-preservative are to after lichee process, slow down the brown stain of the rotten of lichee and pericarp thereof, effectively maintain the color of lichee pericarp, there is good fresh-keeping effect, be beneficial to the preservation and freshness of lichee, be very suitable for production application.
Obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
