Description
Technical field
The present invention relates to a kind of drying means of carrot more particularly to a kind of full nutrition carrot Ultramicro-powder preparation sides
Method.
Background technique
Carrot is crisp delicious, the full of nutrition homely vegetables of a germplasm, is known as the title of " glabrousleaf asiabell root ".Carrot is rich in sugar
The nutritional ingredients such as class, fat, volatile oil, carrotene, vitamin A, vitamin B1, vitamin B2, anthocyanidin, calcium, iron.Separately contain
Pectin, starch, inorganic salts and a variety of amino acid.In each veriety, You Yishen Chinese red carotene carotene content highest.American science
Family's research confirms: eating two carrots daily, blood cholesterol can be made to reduce 10%-20%;Three carrots are eaten daily, are facilitated
Prevent heart disease and tumour.
Freeze Drying Technique is much studied and is reported in the application that carrot drying is processed at present, it and drying, hot
The carrot of wind seasoning production is compared, and not only effective component etc. is not damaged, can keep to the maximum extent the color of fresh goods, perfume (or spice),
Taste, nutritional ingredient, appearance and active material.Such as: number of patent application: 201510612336.8, disclose a kind of carrot fruit
The preparation method of piece, it is the carrot for selecting nuisanceless no disease and pests harm, and the maturity control of carrot is in 9 maturations;It will be above-mentioned
Raw material is rinsed well by repeated multiple times clear water, and removes the stem of carrot;Double centner carrot is cut by shredding machine
The fragment of 1cm size, then rotten shape is stirred into pulper;First time glue mill is carried out using carrot of the rubber mill to rotten shape;Simultaneously
3000 grams of water are added to be dissolved into snail enzyme solutions using 20 grams of glusulases;3 kilograms of tune are added in material after completing first time glue mill
Good snail enzyme solutions, second of glue for carrying out material and snail enzyme solutions are ground, and glue mill temperature control is at 36 DEG C, fineness of materials control
System is in 105 mesh;Material is placed on refrigerator tray 1 hour after second of glue mill, then -15 DEG C of use of anxious temperature of freezing carries out material
It is anxious to freeze, until material condenses into bulk;Block-like material is congealed into after suddenly freezing is sent into vacuum freeze-drying machine progress vacuum freeze-drying 20 hours,
Material moisture is controlled 4%, material is made to form orange red powder;In the air conditioning chamber with dehumidifier function, set by tabletting
It is standby that orange-red carrot freeze-dried powder is pressed into piece, product is obtained after packaging.However, these vacuum freeze-drying techniques freeze
Drying time is all very long, and energy consumption is big, and the production cycle is long, constrains the industrialized production of Freeze Drying Technique.In some sides
Freeze-drying time could be saved when in method by being cut into very thin thickness, but yield just declines, specific energy consumption is increased by.In certain methods
Needing to be added additional auxiliary material could be beaten, forms, be lyophilized, and increase production cost, change some original characteristics of medicinal material.
To solve drawbacks described above, there is higher cost for vacuum freeze drying, the production cycle is long, and big wait of specific energy consumption lacks
Point, inventor have carried out a large amount of research work, propose a kind of new preparation method.
Summary of the invention
Present invention aims to overcome that the shortcomings of the prior art, propose a kind of to be rapidly frozen dried carrot ultra micro
The method of powder shortens the production cycle being entirely lyophilized, and specific energy consumption and cost, which is lyophilized, to be reduced, but also sufficiently keeps fresh Hu
Effective component, the nutritional ingredient of radish, Ultramicro-powder obtained can be dissolved into rapidly molecule after adding water, and rehydration speed is fast, multiple
Its color, quality and fresh goods are essentially identical after water.
To achieve the goals above, present invention employs technique below and steps:
A kind of full nutrition carrot superfine preparation method, it is characterised in that this method includes the following steps:
1) it by the carrot of fresh harvesting, washes with water completely, drains;
2) pretreated carrot is squeezed, collects carrot juice and carrot pomace respectively;
3) carrot juice of step 2 is put into dryness storehouse pallet, dryness storehouse is vacuumized, certain pressure and at a temperature of it is dry
Dry a period of time;Then material is cooled to -35 DEG C~-40 DEG C, maintained 1~3 hour;The shelf in dryness storehouse is added again
Heat is passed through mixed gas from dryness storehouse top, and control pressure is 50~100Pa, and material is made to rise to 0 DEG C from -35 DEG C~-40 DEG C,
Lyophilization 4~6 hours, material rose to 30 DEG C from 0 DEG C, parsing-desiccation 1~2 hour, was forced into export after normal pressure;
4) carrot pomace of step 2 is put into dryness storehouse, under the conditions of 10~50Pa of pressure, -35 DEG C~-40 DEG C of temperature,
Freeze 1~2 hour;The shelf in dryness storehouse is heated again, is passed through mixed gas from dryness storehouse top, control pressure is 50
~100Pa makes material rise to 0 DEG C from -35 DEG C~-40 DEG C, and lyophilization 4~6 hours, material rose to 30 DEG C from 0 DEG C, and parsing is dry
Dry 1~2 hour, it is forced into export after normal pressure;
5) by after drying carrot juice and carrot pomace carry out 5~10min of crushing with airslide disintegrating mill at 30 DEG C or less together,
It is the 5% full nutrition Ultramicro-powder of carrot below up to biodiversity content;
6) it packs: carrot full nutrition Ultramicro-powder is fitted into clean packaging, airtight vacuum or rush nitrogen and pack.
Further, pressure and temperature control certain described in step 3) is 10~50Pa and 30 DEG C~40 DEG C, drying time
It is 4~6 hours.
Further, step 3), 4) gas being passed through is the mixed gas of Krypton and neon, mixing mass ratio is 1%~
4%, the gas temperature being passed through is controlled at 20~30 DEG C.
Further, grain size of micropowder reaches 10 μm or less after crushing described in step 5).
Compared with prior art, the invention has the following beneficial technical effects.
The present invention is separated juice and slag using the method for physics, is then concentrated, is lyophilized respectively etc. and operates, whole process
All it is to be handled in low temperature environment, does not destroy thermal sensitivity, active constituent and effective component.Material after freeze-drying is in loose
Porous spongy, the time and difficulty, the submicron powder sheet finally obtained for greatly reducing later period crushing can dissolve rapidly after adding water
At molecule, rehydration speed is fast, its color, quality and fresh goods are essentially identical after rehydration.
The present invention is combined using low-temperature vacuum drying and freeze-drying reasonable arrangement and effectively, and entire preparation process does not have
Other auxiliary materials are added, so that whole preparation process unit total energy consumption be made to reduce at least 50% or more, yield in unit time is improved at least
50% or more, while successfully remaining fresh goods color, effective component, nutritional ingredient etc..
Drying process of the present invention both ensure that it is dry after the color of material, quality it is consistent with fresh goods, it is effective retain it is effective
Ingredient, active component content, and reduce freeze-drying time, accelerate freeze drying rate, reduces specific energy consumption, be conducive to production cost
It saves.
Product after present invention freeze-drying using vacuum or nitrogen-filled packaging and is kept in dark place, and long shelf-life is more advantageous to product
Stability during storage.
