Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, and the technical scheme of a kind of winter jujube fruit squash and processing method thereof is provided.This technical scheme utilizes the winter jujube to process fruit squash for raw material, has not only kept original local flavor of winter jujube but also has kept the nutritional labeling of winter jujube, and quality also has better lifting.
For achieving the above object, the technical scheme that the present invention adopts is:
Described winter jujube fruit squash is a raw material with the winter jujube, and white granulated sugar, citric acid, compound stabilizer etc. are auxiliary material, process by following prescription:
Winter jujube 30~50%;
White granulated sugar 5~7%;
Citric acid 0.3~0.6%;
Compound stabilizer 0.1~0.4%;
Water surplus.
Said compound stabilizer comprises sodium alginate, sodium carboxymethylcellulose, xanthans, and its mass ratio is 4: 4: 3; Said water is distilled water, mineral water or pure water.
Above-mentioned winter jujube fruit squash processing method is that the several steps according to following order carries out:
(1) blanching is put into blanching machine with the raw material jujube after the acceptance(check), 90~95 ℃ of blanchings 3~6 minutes;
(2) clean cooling, the raw material jujube of step (1) gained is cleaned, is cooled to 40~50 ℃ with cold water;
(3) making beating with the raw material jujube of step (2) gained, is served conveyer belt by elevator, from beater entering beater suitable for reading, adds entry by the jujube quality than 1: 2, obtains slurries;
(4) the glue mill carries out levigate processing with slurries with colloid mill, and being milled to fineness is 40~60 μ m, and fine grinding becomes homogenate 2~3 times;
(5) centrifugal, centrifuge is carried out in levigate homogenate centrifugalize, remove fructus corni and other impurity, obtain the jujube slurry;
(6) allotment is sent the jujube slurry into blend tank; Take by weighing the sugared equipment of sending into of white granulated sugar by formula rate, add water at 1: 1 according to the mass ratio of white granulated sugar and water, heating for dissolving obtains liquid glucose, after duplex strainer filters, is sent to the blend tank that the jujube slurry is housed; Take by weighing citric acid and compound stabilizer by formula rate again, with an amount of warm water dissolving, be sent to blend tank, in blend tank, supply water to the scale that requires, stirring obtains winter jujube Normal juice;
(7) degassing, the raw material jujube itself contains aerobic, can cause also that in process the secondary of air is sneaked into, and influences juice quality, is unfavorable for the stability of fruit juice, therefore, adopts the mode of vacuum outgas to remove the gas in the fruit juice in the production;
The winter jujube Normal juice that allotment is good is got to the operation of bleeding in the vacuum receiver with pump; The temperature of control appropriate vacuum and winter jujube Normal juice, 20~25 ℃ of degassing temperature.Vacuum in the degassing tank is 90~93KPa; Adopt the mode under the Film Flow, be beneficial to the abundant degassing;
(8) homogeneous, the Winter jujube juice beverage belongs to pulp type beverage, and lamination often takes place in postpone for a long time; Make the miniaturizations such as slurry grain in the product through homogeneous, not only reduce its granular size, change the distribution of its particle diameter simultaneously; Make Winter jujube juice keep certain turbidity, thereby reduce deposition to greatest extent; At pressure 20~25Mpa, inlet temperature is a homogeneous 2 times in 60~65 ℃ the high pressure homogenizer;
(9) sterilization can, the superhigh temperature instantaneous sterilization, temperature adopts 125 ℃, 4~6 seconds instantaneous sterilization; One of the purpose of instantaneous sterilization is the enzyme that goes out, and another is the microorganism of killing in the product, prevents that product is rotten when storing and drinking; After finishing, sterilization adopt the normal pressure sterile filling to get winter jujube fruit squash;
(10) two-stage sterilization, spray cooling after can finishes, after can finishes, adopt the spray sterilization machine that tank body is carried out two-stage sterilization, and control material sterilizing time was at 20 minutes; Spray plays cooling effect simultaneously, gets finished product after product temperature is reduced to 25~30 ℃.
Compound stabilizer described in the processing method comprises sodium alginate, sodium carboxymethylcellulose, xanthans, and its mass ratio is 4: 4: 3; Said water is distilled water, mineral water or pure water; Adopting beater in the making beating step is the two pass beater, broken together, the making beating of two roads, and this step can be removed jujube nuclear and most of fructus corni; The centrifuge that adopts in the said centrifugation step is a horizontal spiral centrifuge, and the FREQUENCY CONTROL of its frequency converter is 35Hz.
Adopt the fresh fruit beating process in the above-mentioned winter jujube fruit squash processing step, guaranteed the quality and the nutrition of winter jujube fruit squash.
The present invention compared with prior art has the following advantages:
1, the present invention is the raw material processing fruit squash of directly pulling an oar with bright winter jujube, has kept the dietary fiber and the nutritional labeling of winter jujube preferably, and the bright jujube local flavor of winter jujube;
2, the present invention has increased blanching technology, makes jujube fruit beating results obviously improve, and jujube meat is easy to separate with nuclear, skin, and the slurries quality has a distinct increment;
3, adopt HTHP to carry out homogeneous, homogenizing effect is good, and beverage liquid is more even;
4, this project adopts an amount of compound stabilizer, makes the fruit squash of processing have stronger stability, thereby has guaranteed product quality.
