Abstract
The invention discloses a kind of processing method for being dehydrated chive leaf, it is characterised in that：Specific steps include：1）Feedstock treating, 2）Infiltration, 3）Precooling and 4）The chive that the step process such as vacuum freeze drying are dehydrated.The inventive method is while ensureing to follow lyophilization method characteristic, due to there is no frozen step to material, so power consumption is significantly lower than lyophilization technique, processing cost is greatly reduced, ensure that the color and luster of chive, taste are constant simultaneously, it is also possible to the characteristics of being kept for the quality time long.
Description
Technical field
The invention belongs to technical field of agricultural product process, it is related to a kind of processing method for being dehydrated chive leaf.
Background technology
China is large agricultural country, vegetables as the second largest industry in China's agricultural production, but in circulation, the overwhelming majority
Vegetables are appeared on the market of farm produce in the hair dish form without any treatment, high if cannot sell completely that post-harvest loss high will be caused
Cost circulates, high environmental pollution.Fresh-keeping, quick-frozen, the small chive sales volume of diving of big and medium-sized cities supermarket of China constantly increase.Especially
It is some developed countries and regions, such as Japan, Hong Kong, South Korea, Holland, the U.S., Singapore, France, the vegetables to China go out
Mouth demand is bigger.Therefore, the fresh-keeping problem during vegetables and fruit outward transport is solved, urban vegetable and water can be further improved
Level, the quality of fruit supply, expand foreign exchange earning, increase vegetable grower's income, and prosperity urban and rural economies improve comprehensive benefit, are vegetables
The inexorable trend of industry development.
As living standards of the people are increasingly improved, rhythm of life is accelerated, and people have been unsatisfactory for the single form of vegetables fresh eating,
People are increasing to pollution-free green food, the demand of organic food.Small chive is to cook, do based on edible tender leaf
Fish and indispensable condiment when cooking soup, are also the principal item of Dehydrated Vegetable Processing.Pollution-free green food, organic food
Essential in seasoning is exactly small chive, therefore, it is important development direction that exploitation is dehydrated small chive and fresh-keeping small chive product,
Can not only obtain people and be rich in local flavor, nutritious, safety and sanitation, convenient and practical, the economical and practical small chive of all kinds of additions
Product, is also the effective way for solving small chive dull and rush season imbalance between supply and demand.
However, in the prior art, it is easily caused that vegetables color and luster is gloomy, taste is changeable to the dewatering of vegetables, and is difficult to grow
Phase keeps quality, therefore urgently researches and develops a kind of method of the dewater treatment of chive.
The content of the invention
A kind of deficiency it is an object of the invention to be directed to existing chive dehydration technique, there is provided the processing of dehydration chive leaf
Method.
To achieve these goals, present invention employs following technical scheme：
A kind of processing method for being dehydrated chive leaf, the method is comprised the following steps：
1）Feedstock treating：Fresh chive leaf is cleaned, and it is 40 ~ 60KHz, ultrasound that immersion has alkali lye to carry out supersonic frequency after cleaning
Power is 300-500W, and temperature is 3 DEG C -8 DEG C, the ultrasonication of process time 3-5min, then is cleaned with clear water, segment, dress
The fresh chive leaf handled well is obtained after disk；
2）Infiltration：Then infiltration treatment is filtered dry during chive is immersed in compounding liquid glucose；
3）Precooling：The fresh chive leaf precooling at 4 DEG C that will be handled well, pre-coo time is 0.7 hour；
4）Vacuum freeze drying：By the fresh chive leaf after precooling, the vacuum freeze drying cabin of vacuum freeze is inserted
In fresh chive leaf is thermally dried, heating-up temperature be 100 DEG C, the vacuum of vacuum freeze drying cabin is in drying process
900-1500pa, condenser temperature is -21 DEG C, dries to the moisture of chive leaf and dehydration chive leaf is obtained less than 3%.
Further, the alkali lye of described step (1) is edible Na2CO3 or NaHCO3 solution, and concentration is 0.9%.
Further, step 2）Described infiltration treatment control time is 10min-20min.
Further, step 2）The described compounding liquid glucose amount of attaching most importance to compares 2: 1 glucose：Lactose, concentration is 8%
Further, step 4）The middle heat drying time for controlling is 8-9 hours.
Beneficial effects of the present invention：
The inventive method ensure follow lyophilization method characteristic while, due to there is no frozen step to material, thus consumption
Lyophilization technique can be significantly lower than, processing cost is greatly reduced, while ensure that the color and luster of chive, taste are constant, also can
The characteristics of enough keeping the quality time long.
Specific embodiment
It is described in further detail to specific embodiment of the invention below.
Embodiment 1：
A kind of processing method for being dehydrated chive leaf, the method is comprised the following steps：
