Abstract
The invention discloses a preparation method of a concentrated sugarcane juice. A traditional production method of the concentrated sugarcane juice has the disadvantages of easy causing of the destroy to the nutritional components in the sugarcane juice, appearance of precipitation and turbidity in a finished product in the storage life, deep and reddish color and bitter taste of the concentrated sugarcane juice, no guarantee of the continuous production, and low production efficiency. The preparation method comprises the technological steps of tearing and juicing, pre-disinfecting and killing enzymes, centrifuging for particle removal, carrying out enzymatic hydrolysis, ultrafiltering, concentrating and disinfecting against the macromolecular substances comprising proteins, enzymes, pectin, starches and the like in the sugarcane juice. The concentrated sugarcane juice prepared through using the method has the advantages of good clarity, delicate fragrance, sweetness, and no precipitation or turbidity during the storage life; and the longtime problems of bad clarity, bad color and appearance of precipitation during the storage life of the concentrated sugarcane juice, caused by the influences of the enzymes and pigments, are solved.
Description
Technical field
That the present invention relates to is the preparation method of concentrated sugarcane juice, belongs to the fruit juice food processing technique field.
Background technology
Sugarcane is the distinctive a kind of fruit in subtropical zone, and its juice is abundant, the sugar content height, and sense of taste is fresh and sweet, extensively is subjected to liking of people.Sugar-cane juice is made beverage, huge market prospects are arranged, because the mouthfeel of sugar-cane juice is subjected to generally liking of people.Cooking beverage with sugar-cane juice has two kinds of methods, and a kind of is exactly directly to squeeze sugar-cane juice, synthetic beverage; Another kind is exactly with sugarcane inspissated juice synthetic beverage.Beverage/food processing enterprise can not directly use the sugar-cane juice synthetic beverage, and preparing sugarcane beverage at present all is to produce sugarcane beverage with the sugarcane inspissated juice as raw material mostly.Sugarcane inspissated juice quality good or not is mainly reflected in clarity, flavour and taste, color and luster, the such index of solid content, and the variation of the sediment of storage period and physical property thereof, if these indexs all reach requirement, product must have the extremely strong market competitiveness.And in the present disclosed report, the quality index of concentrated sugarcane juice or product quality also find no and meet the requirements of, tracing it to its cause mainly is the problem of production method, what the production method of tradition sugarcane inspissated juice mainly adopted is lime-phosphoric acid sedimentation, be behind sugar cane crushing, to add phosphoric acid and limewash, thereby making it produce chemical reaction generates phosphate and impurity in the sugar-cane juice is precipitated separate out, obtain the reasonable sugar-cane juice of clarity after the filtration thereupon.But this method need keep sugar-cane juice in the condition of high temperature for a long time, nutritional labeling in the sugar-cane juice has been caused destruction, if acid-base value control is bad, can cause the storage of finished products phase to produce precipitation and muddy, the limewash and the phosphoric acid that add, incomplete problem must respond, there are phosphate radical or limewash residual in the product, there is food security hidden danger, the concentrated sugarcane juice color and luster of producing with this method is dark and red partially, astringent taste is arranged, this method can not guarantee continuous production in addition, and production efficiency is low, can produce precipitation or muddy at its product of storage.Therefore it is necessary providing a kind of production method of high-quality concentrated sugarcane juice.
Summary of the invention
Purpose of the present invention provides the preparation method of concentrated sugarcane juice.Overcome existing concentrated sugarcane juice produce in existing color and luster bad, residual impurity, the problem that production efficiency is not high.
The foregoing invention purpose is achieved and is because adopted following technical scheme: the preparation method of concentrated sugarcane juice comprises the steps:
(1) tear, squeeze the juice: through cane crusher sugarcane is pressed extracting juice again after using cane shredder that clean sugarcane is torn, it is standby to obtain sugar-cane juice through beater elimination impurity;
(2) the pre-sterilized and enzyme that goes out: sugar-cane juice is heated to 95-100 ℃ and kept 3-5 minute, carries out pre-sterilized, the enzyme and make the protein inactivation sex change of going out, and it is standby to obtain hot sugar-cane juice;
(3) the centrifugal particulate that goes: hot sugar-cane juice in centrifuge with rotating speed is 〉=4000 rev/mins the centrifugal solid content of removing of speed, makes the solid content in the sugar-cane juice be less than 0.5%, and it is standby to clarify sugar-cane juice;
(4) enzymolysis: will clarify sugar-cane juice and deliver to heat exchanger and cool off, be cooled to 50-55 ℃, be transported to enzymatic vessel then and carry out enzymolysis, adding activity during enzymolysis is the pulp enzyme of 2000-6000u/ml, make the enzyme content of clarification sugar-cane juice reach 200-300ppm, enzymolysis time 60-90 minute, it was standby to obtain the enzymolysis sugar-cane juice;
(5) ultrafiltration: the enzymolysis sugar-cane juice is delivered to ultrafiltration work jar, is that the milipore filter of 0.01-0.1 micron carries out ultrafiltration with the aperture, reaches turbidity less than the quality requirement of 5.0NTU when sugar-cane juice after the ultrafiltration is calculated with 12.0 ° of Bx, and it is standby to obtain the ultrafiltration sugar-cane juice;
(6) concentrate, sterilize: use the triple effect vacuum concentrator that the ultrafiltration sugar-cane juice is concentrated into technological requirement pol index, heating-up temperature≤90 ℃ are imitated in control one when concentrating, the system vacuum degree≤-0.093Mpa, obtain concentrated sugarcane juice, be cooled to room temperature rapidly, place in the basin to stir, carry out pasteurize with board-like sterilization line, be cooled to 18-20 ℃ then rapidly, packing namely.
Take the present invention of above-mentioned measure, having adopted three step master operations in preparation process, is exactly the sugar-cane juice pre-sterilizing, the enzyme that goes out, enzymolysis and ultrafiltration, in sugar-cane juice pre-sterilizing, the enzyme step of going out, sugar-cane juice is heated to 95-100 ℃, this with regard to make in the sugar-cane juice protein denaturation and become precipitation and disengage, be to make the sugar cane juice clarification effective measures, in heating process, also the oxidizing ferment deactivation in the sugar-cane juice, oxidizing ferment can impel the sugar-cane juice oxidation and color burn, influence the outward appearance of product; The sugar-cane juice enzymolysis step is to add organized enzyme in sugar-cane juice, macromolecular substances such as the pectin in the sugar-cane juice, starch decomposed, thus the product that obtains clarifying, and make product in storage period, not produce precipitation and muddy, improve product quality stability; Ultrafiltration step is the solid content in the sugar-cane juice and macromolecular substances elimination, thereby improves the clarity of product.Products obtained therefrom of the present invention has following quality index:
| Project | Index |
| Soluble solid (20 ℃ of compound microcapsules), % | 60.0 ±1.0 |
| PH value | 4.0-6.0 |
| Total acidity (in anhydrous citric acid), % | ≤0.9 |
| Solid content (soluble solid is 12% o'clock), V/V% | N/A |
Products obtained therefrom concentrated sugarcane juice clarity of the present invention is good, delicate fragrance is sweet, lay up period not precipitation disengages, and does not also have muddy the generation, and having solved for a long time, concentrated sugarcane juice causes the product clarity bad because of the influence of enzyme, pigment, color and luster is not good, the problem that has storage period precipitation to disengage.Concentrated sugarcane juice by the present invention produces has the very strong market competitiveness because have good quality, and the present invention can produce continuously in addition, has solved the shortcoming of the necessary batch production of traditional sugar cane juice clarification.
