Abstract
The invention discloses a production method of freeze-dried carrot crisp chips. The production method disclosed by the invention comprises the following steps of: firstly, peeling carrots, and slicing carrots into chips; after spreading the sliced carrot chips in a dish, feeding into a hot air drying box, drying by using hot air for 40-60 min while controlling the temperature at 60-90 DEG C, after drying by using hot air, pre-freezing the carrot chips at minus 40 to minus 70 DEG C for 16-20 h, after pre-freezing, putting the carrot chips in a vacuum freeze drying machine, and freeze-drying in vacuum at minus 50 DEG C for 24 h to obtain the freeze-dried carrot crisp chips. According to the production method of the freeze-dried carrot crisp chips disclosed by the invention, because the hot air drying technology and the vacuum freeze drying technology are combined, the drying energy consumption is reduced; the drying efficiency is increased; the produced carrot crisp chips are low in nutrition loss, healthy and environment-friendly; the primary colour and the primary taste of the carrot crisp chips are greatly kept.
Description
Technical field
The invention belongs to technical field of drying, relate in particular to a kind of preparation method of freeze-drying carrots chips.
Background technology
Carrot nutritional is abundant, contain the various trace elements such as zinc, calcium, iron and 8 kinds of essential amino acids and dietary fiber, particularly be rich in β-carrotene, the health of human body is had to very useful health-care effect, carrot and deep processed product thereof are loved by the people, and are the main carrot deep processed products of one of the countries such as current China's export Japan, Southeast Asia and European Union.But the at present normal pressure heated-air drying gained that adopt more, the color of product is dark, nutritive loss is large, and the product quality of many enterprises is difficult to reach export requirement.But carrot after vacuum freeze drying can keep its original local flavor and nutritional labeling preferably, effectively solve the problem that said method exists.But the quality requirement for freeze-drying carrot product is: biologically active is constant, appearance luster is even, form is full, sound construction, dissolution velocity are fast, and residual moisture is low.At present, the problem that domestic carrot product exists in freeze-drying process is: on brightness in storage, red degree and yellow degree, relatively fresh carrot decline is very fast, and color distortion degree is large, affects shelf life and product quality.
Combined drying refers to a kind of composite drying technology that 2 kinds or two or more drying mode carry out stage by stage, its objective is will reduce drying time, reduce energy consumption, improve the quality of products.
Heated-air drying has that energy consumption low (for other drying means), production method are relatively simple, output advantages of higher; But also there are many deficiencies, as large in product shr, color and luster brown stain is serious, reconstitution rate is low, nutrient loss is serious etc.
Freeze drying can change above-mentioned quality defect, can keep to greatest extent the color, smell, taste and shape of food and good rehydration; Its weak point is that operating technology requirement is high, energy consumption large, serialization is produced difficulty, yielded poorly, thereby operating cost is high, has greatly restricted the development of the sector.
In sum, heated-air drying and freeze drying process are combined, find suitable transfer point, make energy consumption cost, guarantee simultaneously carrots chips fresh colour, former flavoursome, organize fresh and crisp, piece shape is complete etc.
Product prepared by this technique is except the radiation effects of self, the enforcement of the freeze-dry process of the research also will drive the whole freeze-drying industrial expansion of China, the difficult problem of fading that solves the dried frozen aquatic products of the whole freeze-drying industrial quarters of puzzlement, the freeze-dry process of setting up, will the competitiveness of enterprise in colleague.
Summary of the invention
One of object of the present invention is to provide a kind of profile, hue preserving good, and nutritional labeling loss is less and can improve the preparation method of the freeze-drying carrots chips of drying efficiency.
Technical scheme of the present invention
A preparation method for freeze-drying carrots chips, specifically comprises the steps:
(1), the fresh carrot cleaning up is peeled, be cut into the thin slice that thickness is 3 ~ 15mm;
(2), the carrot thin slice pure water cleaning of gained afterwards of cutting into slices is put into 80 ~ 100 ℃ of hot water after draining and carry out blanching 3 ~ 8min;
(3), by the balance that tiles of the carrot thin slice after blanching, balance thickness is no more than 25mm, and packs the carrot thin slice that sets dish into drying receptacle;
Described drying receptacle is culture dish, crisper or aluminum pallet;
(4), that the drying receptacle that carrot thin slice is housed is put into hot air drier is dry, dry run control temperature is 60 ~ 90 ℃, the time is 40 ~ 60min;
(5), after heated-air drying finishes, immediately the drying receptacle that carrot thin slice is housed is carried out to pre-freeze, pre-freeze temperature is-40 ~-70 ℃, and the pre-freeze time is 16 ~ 20h;
(6), carrot thin slice good pre-freeze is placed in vacuum freeze drier and is dried, baking temperature is-50 ℃, and be 24h drying time, obtains freeze-drying carrots chips.
After finishing, above-mentioned vacuum freeze drying immediately the freeze-drying carrots chips of gained is encapsulated.
Beneficial effect of the present invention
The preparation method of a kind of freeze-drying carrots chips of the present invention, due to heated-air drying and Vacuum Freezing & Drying Technology are combined, has reduced energy consumption for drying, has improved drying efficiency, and the carrots chips nutritive loss of production is little, health environment-friendly.
Further, the preparation method of a kind of freeze-drying carrots chips of the present invention, prevent Browning Mechanism and the carrots chips characteristic in dehydration process according to carrots chips, adopt in advance blanching processing, blanching pretreatment has effectively prevented enzymatic browning, has greatly retained the original color and taste of carrots chips.
