Description
Technical field
The present invention relates to field of food industry, more particularly to a kind of glucose syrup production technology.
Background technology
Glucose syrup is a kind of a kind of caused starch syrup, main component in the presence of enzyme or acid using starch as raw material
It is glucose, maltose, maltotriose, maltotetraose and tetrose with first-class, also known as liquid glucose, domestic production at present
The method of glucose syrup, all it is using pure starch as raw material, is made through alpha-amylase and Glucoamylase hydrolysis, this production method needs
Drying equipment is used, efficiency is low and production cost is high；
The area of China plantation sugarcane or beet is lacked compared with the area of plantation corn simultaneously, the use of sugarcane or beet is raw material
Production method causes season limit of the production by raw material, and carrys out extra earning without other accessory substances so as to reduce sugar making cost；
And the glucose syrup without ion-exchange treatment, its is of low quality.
The content of the invention
For the deficiencies in the prior art, it is an object of the invention to provide the grape that a kind of cost is low, quality is high
Syrup production technology.

Enter 0.3%CaCl2Solution and the alpha-amylase mixed well with a small amount of water, starch slurry is made；
(3) liquefy
Starch slurry is pumped into jet cooking device and is heated to more than 90 DEG C, the slurries of partial liquefaction are sent into after 5min and protected
In warm tank, 88-90 DEG C is rapidly cooled to, and is incubated 30-60min, negative to starch reaction, starch resolves into dextrin, and slurries are dilute
Thin, liquefaction is completed, and 10min sterilising and enzyme inactivatings are boiled in heating；
(4) it is saccharified
Liquefier is pumped into insulation saccharifying tank, adds sulfuric acid to adjust PH to 4.0, adds carbohydrase, reaction temperature 60-62
DEG C, reaction time 36h, DE values reach more than 95 end saccharification, boil enzyme deactivation；
(5) decolorization filtering
Saccharified liquid adds the craboraffin of 1-1.5% on dry basis, and decolouring 30min, Ran Houyong are incubated in 80 DEG C
Plate and frame filter press filters, and obtains the transparent liquid glucose of light color；
(6) ion exchange
Be passed directly into by the transparent liquid glucose of the light color of decolorization filtering handle well from hand over bed, be 50-60 DEG C of condition in temperature
Under, cationic ion-exchange resin and anion exchange resin are successively passed through with 3t/h flow velocity；
The liquid glucose just flowed out needs to sample, and examines whether there is precipitation generation with ammonium oxalate and barium chloride solution；
Regeneration treatment is carried out after the production of a period of time from bed is handed over；
(7) it is concentrated in vacuo
In vacuum 600mm mercury column, it is 50-60% that 65-70 DEG C of temperature, which carries out being concentrated into concentration,.
Above-mentioned glucose syrup production technology, during pretreatment, 0.1-0.3% sulfurous acid soaking maizes are used at a temperature of 50 DEG C
48-72h is to decompose the protein in cutin starch.
Above-mentioned glucose syrup production technology, except the thick slurry of degerming, then be ground to can cross 80-120 mesh sieves, gained
Crude starch through centrifuge separating starch and protein.
Above-mentioned glucose syrup production technology, liquefy after enzyme deactivation, the chuck cooling water for opening cooler is cooled.
Above-mentioned glucose syrup production technology, decolorization filtering saccharified liquid is in filter press during press filtration, the liquid glucose that begins to flow out
It is unclear, then need to flow back, untill liquid glucose is clarified.
Above-mentioned glucose syrup production technology, during ion exchange, there is liquid glucose backflow caused by precipitation to carry out handling from friendship again,
Next procedure is delivered to without liquid glucose caused by precipitation.
Above-mentioned glucose syrup production technology, after ion exchange terminates, it will be ejected with clear water from liquid glucose remaining in friendship bed.
Above-mentioned glucose syrup production technology, regeneration treatment water backwash resin, clear up from handing over impurity in bed, then with 6%
Salt solution be slowly passed through resin bed and keep contact 2h, then clean salt solution with clear water.
The beneficial effects of the invention are as follows：The use of corn is that raw material produces glucose syrup, not only than pure Starch Production grape
Syrup eliminates the drying equipment of manufacture starch, at the same can also the higher byproduct of price such as production of albumen powder, corn oil, drop
Low production cost, while ion-exchange treatment further is carried out to syrup after decolorization filtering, obtain the quality of glucose syrup
It is further to improve.

Analysis of conclusion：
(1) from table, as corn powder particles are less and less, sugared rate raises, and filtration flow-rate reduces, and can draw
The corn flour of 100-110 mesh fineness is that preferable working condition, not only sugared rate and filtration flow-rate are more suitable, and raw material adds
Work is relatively easy to.
(2) plumule of corn is separated during coarse crushing, corn oil workshop section can be delivered to after washing, and passed through after grinding thick slurry
Centrifuge may separate out protein, so add the accessory substance of glucose syrup production, improve the utilization rate of raw material, further
Reduce production cost.
(3) only need a pair from hand over bed and brine pit can composition complete set from the system of friendship, salt solution is as again
Raw agent is small to equipment corrosion, and often 1 ton of finished product glucose syrup of production need to only consume 400kg salt, compared with traditional processing technology
Often producing 1 ton of finished product syrup needs to consume hydrochloric acid 100kg, caustic soda 40kg, reduces production cost.
(4) glucose syrup Jing Guo ion exchange, limpid, transparent, outward appearance is beautiful.
The use of corn is that raw material produces glucose syrup, not only eliminates manufacture starch than pure Starch Production glucose syrup
Drying equipment, at the same can also the higher byproduct of price such as production of albumen powder, corn oil, reduce production cost, while decolourizing
Ion-exchange treatment further is carried out to syrup after filtering, the quality of glucose syrup is further improved.
