A kind of vacuum freeze drying glutinous rice coconut group and preparation method thereof
Technical field
The present invention relates to food technology field, especially a kind of vacuum freeze drying glutinous rice coconut group and preparation method thereof.
Background technique
Mochi nutrition in the prior art is single, and packed and transported is inconvenient, and the shelf-life is short, eats restricted, takes
Band is inconvenient, and.Coconut powder nutrition in the prior art is single, is easy breakage, and poor taste is easy discoloration, packing instructions
Height, cost price are high.
Summary of the invention
The present invention is intended to provide a kind of vacuum freeze drying glutinous rice coconut group and preparation method thereof, overcomes prior art defect
And the problem that product nutrition is single, the edible glutinous rice convenience of consumer is improved, does not need to go boiling that can conveniently eat again
The glutinous rice product eaten.
For this purpose, the specific technical solution that the present invention uses is as follows:
A kind of vacuum freeze drying glutinous rice coconut group and preparation method thereof is provided, vacuum freeze drying glutinous rice coconut group
Raw material includes the component of following parts by weight:
Preparation method includes the following steps:
(1) each component is weighed within the above range by different cultivars;
(2) glutinous rice is needed using cold water soak 60-100 minutes, then add 10-11 times of parts by weight of glutinous rice water boiling it is glutinous
Rice, boiling temperature control between 98-100 DEG C, and digestion time was controlled at 60-70 minutes, need to be stirred continuously in the process;
(3) by each coconut albumen juice or coconut powder that weigh up, white granulated sugar, it is edible successively put into well-done glutinous rice, stir
Uniformly;
(4) mixture is worn into slurry shape using colloid milling equipment by the processed material honest material for handling step (3) well;
(5) the mixed molding of homogeneous material is obtained into molding mass using mold or injection molding machine molding equipment;
(6) fruit cut or vegetable stuffing are uniformly paved into moulding mixture surface by the environment by molding mass at -5 DEG C to -8 DEG C;
(7) material for completing fruit or vegetable stuffing is drawn to -25 DEG C quick-frozen 2-3 hours of progress below, must be formed quick-frozen
Material;
(8) before quick-frozen material is dehydrated into furnace, disinfection is cleaned up, spare;
(9) cleaned furnace body, it is glutinous to get vacuum freeze drying by being freeze-dried in quick-frozen material drawing to freeze-drying furnace
Rice coconut group.
Preferably, the moisture content of the vacuum freeze drying glutinous rice coconut group is less than 5%.
Preferably, the coconut albumen juice or coconut powder are the pure natural coconut for not adding any foreign substance that coconut is worn into
Slurry or by the coconut powder of vacuum freezing drying dehydration, when slurry fortune or storage, save at low ambient temperatures.
Preferably, the boiled water that the step (2) also glutinous rice flour can be used to add 6 times is directly reconstituted and cured, wash open
It needs constantly to stir evenly during water.
Preferably, the step (3) uses coconut powder, the parts by weight of addition are the 25% of leaf slurry.
Preferably, the freeze-drying water desorption curve being freeze-dried in the step (9) are as follows: vacuum degree 80-120Mpa, temperature
Curve is as follows: it is warming up to 85 DEG C in 1 hour, constant temperature 6 hours, then 45 DEG C are cooled within 1 hour, last constant temperature 3 hours cools to
30 degree or less can come out of the stove.
A kind of vacuum freeze drying glutinous rice coconut group provided by the invention and preparation method thereof, the beneficial effect is that:
1, overcome prior art defect and product nutrition single, solve the eating method of glutinous rice, coconut, improve consumer's
Edible glutinous rice convenience, does not need to go boiling that can conveniently eat nice glutinous rice product again;
2, various shape can be shaped to, entrance is crisp, be suitble to all personnel as breakfast or dessert articles, especially when
Still young man is edible and eats easy to carry, can be made the fruit or greengrocery product of collocation different taste, can also arrange in pairs or groups
Nut fruits product can more enrich the mouthfeel of product;
3, using freeze-drying fruits and vegetables fourth or cereals fourth, bright and lustrous, characteristic perfume is obvious, and mouthfeel is plentiful crisp.
Specific embodiment
Technical solution of the present invention is further explained and described below by way of specific embodiment.
Vacuum freeze drying glutinous rice coconut group provided in this embodiment and preparation method thereof, the vacuum freeze drying glutinous rice coconut palm
The raw material of son group is by kilogram weighing each component:
Preparation method includes the following steps:
(1) each component is weighed within the above range by different cultivars;
(2) glutinous rice is needed using cold water soak 60 minutes or more, then adds 330 kilograms of cold water of middle glutinous rice and carries out to boiling
Glutinous rice, boiling temperature control between 98-100 degree, and digestion time was controlled at 70 minutes, need to be stirred continuously in the process.
(3) coconut albumen juice weighed up is weighed into 50 kilograms, 1.9 kilograms of white granulated sugar, 15 kilograms of fruits and vegetables fourth, 0.1 kilogram of edible salt,
After sticky rice stewing is good, successively coconut albumen juice, white granulated sugar, edible salt this three kinds of components are successively put into well-done glutinous rice,
It stirs evenly;
(4) the processed material honest material for handling step (3) well carries out mixture to wear into slurry shape using colloid mill equipment;
(5) the mixed molding of homogeneous material is obtained into molding mass using the equipment such as mold or injection molding machine molding;
(6) cut 15 kilograms of fruits and vegetables fourths are uniformly paved into moulding mixture surface by the environment by molding mass in -5 to -8 degree;
(7) by complete fruits and vegetables fourth material draw to subzero 25 it is below carry out it is quick-frozen 2-3 hours, must be formed quick-frozen material;
(8) before quick-frozen material is dehydrated into furnace, disinfection is cleaned up, spare;
(9) quick-frozen material is drawn into freeze-drying furnace and is freeze-dried by cleaned furnace body, the freeze-drying dehydration of freeze-drying
Curve are as follows: vacuum degree 80-120Mpa, temperature curve are as follows: being warming up to 85 DEG C in 1 hour, and constant temperature 6 hours, then dropped through 1 hour
Temperature is to 45 DEG C, last constant temperature 3 hours, and cooling to 30 degree or less can come out of the stove to get vacuum freeze drying glutinous rice coconut group, vacuum
The moisture content of glutinous rice coconut group is freeze-dried less than 5%.
Evaluate identification experiment:
Experiment number totally 32 people, it is dry to a kind of vacuum freeze drying glutinous rice coconut group of above-mentioned preparation, vacuum refrigeration respectively
Dry durian block, three kinds of bread of the durian taste of market sale carry out carrying out sense organ comparison evaluation.
Experimental grade criterion refers to following table:
Experimental result review record is in following table:
Identification is evaluated to summarize:
It evaluates appraiser and amounts to 35 people, score is that score is averaged after each evaluating personnel's evaluation.
Evaluate appraiser composition, 15 people of intra-company, 10 people of customer survey, 15 people of circle of friends.
Originally evaluate identification experiment the result shows that, a kind of product quality of vacuum freeze drying glutinous rice coconut group of the invention
Crisp, color is delicious, full of nutrition, mouthfeel is thick and solid, has glutinous rice and the distinctive fragrance of fruit.
Although specifically showing and describing the present invention in conjunction with preferred embodiment, those skilled in the art should be bright
It is white, it is not departing from the spirit and scope of the present invention defined by the appended claims, it in the form and details can be right
The present invention makes a variety of changes, and is protection scope of the present invention.
