Description
Technical field
The invention belongs to technical field of red jujube processing, and in particular to a kind of freeze-dried fruit composite jujube piece and its manufacture craft.
Background technique
Jujube piece is to use precook, grind mashing, and vacuum and low temperature concentration, booth piece, heated-air drying refine.Since technique is numerous
Trivial, production cycle length, production capacity are very limited, and in order to shorten technique duration, energy saving more caters to children's counterpart simultaneously
Taste and health-nutrition demand now make novel fruits composite jujube piece with tablet making technology is rolled using Vacuum Freezing & Drying Technology,
Namely freeze-dried fruit powder is reconciled to roll through compounding and fruit composite jujube piece is made, obtains the novel jujube that piece piece faint scent has chewy texture
Piece greatly improves the added value of jujube piece while taking into account mouthfeel and fragrance.
Summary of the invention
Aiming at the problems existing in the prior art, the present invention provides a kind of fruit composite jujube piece, using vacuum freeze drying
Technology obtains all good freeze-dried fruit raw material of color, smell and taste, then reaches 100 mesh using air-flow crushing mechanism powder, then use the system of rolling
Fruity jujube piece is made in piece slice process.
A kind of freeze-dried fruit composite jujube piece, it is made of the raw material of following portions by weight: freeze-drying red date powder 30-50,
Apple powder 10-15, freeze-dried strawberry powder 10-15, maltitol liquor 15-20, pure water 5-10, sunflower oil 3-5 is lyophilized.
Preferably, the freeze-dried fruit composite jujube piece, it is made of the raw material of following portions by weight: freeze-drying jujube
Powder 40, freeze-drying apple powder 12, freeze-dried strawberry powder 13, maltitol liquor 18, pure water 8, sunflower oil 4.
The manufacture craft of the freeze-dried fruit composite jujube piece, steps are as follows:
(1) will jujube, apple, strawberry cleaning impurity elimination after slice carry out vacuum freeze drying, -35 DEG C pre-freeze 2 hours, 40-60 DEG C
20h is to moisture≤5% for dryness storehouse freeze-drying, spare；
(2) it by jujube, apple, the strawberry air-flow crushing mechanism powder after freeze-drying, sieves with 100 mesh sieve spare；
(3) according to the proportion, step (2) obtained into freeze-drying red date powder, apple powder, freeze-dried strawberry powder and maltitol liquor be lyophilized, pure
Water purification, sunflower oil are uniformly mixed, and are stirred for becoming dough；
(4) dough that step (3) obtains is rolled into laminar compound fruit slice with noodle press, to prevent adhesion, machine
On spread a small amount of candy sugar powder；
(5) step (4) is obtained into compound fruit slice cutting, then with water vapour sterilization processing jujube piece 1 minute of 100 DEG C, mesh
Sterilizing while make fruity jujube piece mouthfeel finer and smoother.
It is to prevent its oxidation stain from needing to be impregnated color protection 10 minutes with 0.1% sodium chloride and vitamin C after apple cutting.
Compound fruit slice is cut into 1.5*6 centimetres of jujube sheet, every sheet weight 3-5g in the step (5).
Beneficial effects of the present invention: verifying by batch experiment, and the optimum proportioning of fruity jujube piece is freeze-drying red date powder 30-
50%, apple powder 10-15%, freeze-dried strawberry powder 10-15%, maltitol liquor 15-20%, pure water 5-10%, sunflower oil 3- is lyophilized
5%.Fruit after freeze-drying powder again by mixings, reconciliation, roller-compaction, slice, hot steam sterilize nutrient health water
Fruity jujube piece.The chankings bright in color, thickness are uniform, sweet and sour taste, and mouthfeel muscle is glutinous.Now use Vacuum Freezing & Drying Technology and stone roller
Compacting blade technolgy makes novel fruits composite jujube piece, that is, freeze-dried fruit powder reconciled through compounding to roll and fruit is made answers
It closes jujube piece (rolling, which merges fruit powder slurries sufficiently, is of close texture), so that the novel jujube piece that piece piece faint scent has chewy texture is obtained, simultaneous
While caring for mouthfeel and fragrance, the added value of jujube piece is greatly improved.
Relative to the manufacture craft of traditional jujube piece, the present invention uses Vacuum Freezing & Drying Technology, 40-60 DEG C of freeze temperature
The nutritional ingredient in raw material can be retained to greatest extent, preservation of the fruity jujube piece particularly with heat-sensitive nutrition
After (such as VC) has incomparable advantage, fruit raw material freeze-drying to produce fruit powder, purification is rolled in flakes using modulation, also more preferably
The flavor and color for remaining former fruit, compensate for and add fruit and the insufficient defect of flavor in jujube piece.
Specific embodiment
Combined with specific embodiments below, the present invention will be further described.It should be understood that following embodiment is merely to illustrate this
The person skilled in the art of the range of invention and is not intended to limit the present invention, the field can make one according to the content of foregoing invention
