Abstract
The invention relates to a method for performing vacuum freeze drying on kiwi fruits. The method comprises the following steps: S1, performing pretreatment, wherein the step of pretreating comprises picking, sorting, cleaning and disinfecting; S2, performing pre-freezing, wherein the pretreated kiwi fruits are put at a place of minus 35 DEG C to minus 25 DEG C for pre-freezing, and the time is 4-7 hours; and S3, performing vacuum freeze drying, wherein vacuum freeze drying is performed on the pre-frozen kiwi fruits rapidly, the temperature is minus 60 DEG C to minus 55 DEG C, and the time is 10-15 hours. The kiwi fruits obtained after operation by the method can maintain fresh for a long term, the favorable taste of the kiwi fruits is reserved, the quantity of nutritive losses is small, and the kiwi fruits are convenient to preserve and transport, so that the method has important application values.
Description
Technical field
The present invention relates to the freeze-drying method of a kind of fruit, the method being specifically related in vacuum lyophilization Kiwifruit.
Background technology
Kiwifruit is the plant of Actinidiaceae Actinidia, is a kind of healthy fruit being subject to ordinary populace and welcoming. In its fruit, ascorbic content is high especially, is described as " king of fruit " or " king of Vc ". In addition, also containing necessary 17 seed amino acids of human body and tartaric acid, citric acid and several mineral materials element etc. in Kiwifruit. But the Kiwifruit fruit that to be a kind of easy damage perishable, not easily places after its maturation for a long time, this is a kind of challenge greatly for the transport of Kiwifruit or preservation etc.
Summary of the invention
It is an object of the invention to provide a kind of method of vacuum lyophilization Kiwifruit. It is an object of the invention to be achieved through the following technical solutions:
A method for vacuum lyophilization Kiwifruit, comprises pre-treatment, pre-freeze, vacuum lyophilization and packaging, and described step concrete grammar is as follows:
S1: pre-treatment: comprise harvesting, arrangement, clean and sterilization, pluck health, without disease and pest, not damaged and the Kiwifruit meeting specification of quality, and carry out taxonomic revision by size, sterilizing after cleaning clean, draining, being used for the thimerosal composition of sterilization is made up of potassium permanganate solution and chlorine bleach liquor;
S2: pre-freeze: pre-freeze will be carried out at pretreated Kiwifruit puts into-35��-25 DEG C, the time is 4��7h;
S3: vacuum lyophilization: carrying out rapidly vacuum lyophilization by for the Kiwifruit after freezing, temperature is-60��-55 DEG C, and the time is 10��15h;
Further, potassium permanganate solution described in step S1 is the potassium permanganate solution of 0.1%.
Further, chlorine bleach liquor described in step S1 is the chlorine bleach liquor of 100ppm��300ppm.
Further, the vacuum tightness in step S3 is 70pa��120pa.
The present invention provides a kind of method of vacuum lyophilization Kiwifruit, its useful effect mainly having is: after being operated by the method, the Kiwifruit of gained can the maintenance of longer-term fresh, remain the good taste of Kiwifruit, and nutrition leak is few, preserving, transport convenient, the method has important using value.
Embodiment
The method of a kind of vacuum lyophilization Kiwifruit described in the embodiment of the present invention, illustrates embodiment for specific experiment case below, it will be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Embodiment
1. pre-treatment: comprising harvesting, arrangement, clean and sterilization, a. plucks: pluck health, without disease and pest, not damaged and the Kiwifruit meeting specification of quality; B. arrange: after harvesting, carry out taxonomic revision by size etc.; C. cleaning: cleaned by Kiwifruit, clean after totally and drain the water, then sterilize, the thimerosal composition being used for sterilizing is made up of potassium permanganate solution and chlorine bleach liquor; Preferably, described potassium permanganate solution is the potassium permanganate solution of 0.1%; Described chlorine bleach liquor is the chlorine bleach liquor of 100ppm��300ppm.
2. pre-freeze: carrying out pre-freeze at pretreated Kiwifruit puts into-35��-25 DEG C, it is preferable that pre-freeze at-30 DEG C, the time is 4��7h; Make Kiwifruit core temperature rapid reduction, moisture is fully freezed;
3. vacuum lyophilization: carrying out rapidly vacuum lyophilization by for the Kiwifruit after freezing, temperature is-60��-55 DEG C, and the time is 10��15h; Vacuum tightness be generally 70��120pa just can, after Kiwifruit freeze-drying, terminate vacuum lyophilization.
4. pack: Kiwifruit complete for vacuum lyophilization is loaded in weather-proof dressing bag, namely becomes vacuum lyophilization Kiwifruit.
The present invention is not limited to above-mentioned preferred forms, and anyone for the present invention any modification done under the enlightenment of the present invention or change, every have the technical scheme identical or close with the application, all drops within protection scope of the present invention.
