Abstract
A process for preparing glucose with corn starch features that during liquefying with amlyase, CaCl (0.01-0.05%) and sodium hydroxide (weight ratio to corn starch is 1.1-1.2) is added and during saccharifying, carbohydrase is added for shorter period, higher utilization rate, less investment in apparatus, no corrosion to apparatus and higher activity of enzyme, resulting in high convension rate of grains up to 95%.
Description
The present invention relates to a kind of food chemical industry, especially Semen Maydis powder is produced the glucose making method.
The production method of tradition glucose is, and to be starting material with the starch that grain-production goes out make through liquefaction (amylase), saccharification, press filtration, evaporation, various commerieal sugar, and the production cycle of this method is long, cost height, complex process.Chinese patent 91107288.8 discloses a kind of " method of directly producing glucose from maize enzyme acid ", and it is after corn is made the powder oar, by enzyme (amylase) liquefaction, uses acid (hydrochloric acid) to carry out saccharification again, carries out following process then and forms glucose.Though this method is than traditional technology conserve water consumption, grain consumption, energy consumption and labor force, the process-cycle is still longer, and the utilization ratio of grain is also not too high, exists impurity in the product, and equipment corrosion is more serious.
The purpose of this invention is to provide a kind of Semen Maydis powder and produce the glucose making method, liquefy, improve the utilization ratio of grain, shorten the work period by alkali is enzyme-added; Utilize saccharifying enzyme to carry out saccharification, the fresh vigor of protective enzyme makes equipment do not corroded simultaneously.
The object of the present invention is achieved like this: the catalyzer that changes liquefaction and saccharification in processes well known-corn, one-tenth powder, liquefaction (amylase), saccharification, press filtration, evaporation, various commerieal sugar.It is characterized in that: in the process that liquefies with amylase, add CaCl
20.1 ‰-0.5 ‰ and caustic soda, the proportion of caustic soda and Semen Maydis powder is 1.1-1.2; Amylase in the liquefaction process is to make 25 vigor with the α-Dian Fenmei of per 1 milliliter of 20000 vigor measure unit by per 1 gram starch to calculate; In saccharifying, add saccharifying enzyme and carry out saccharification, and make 200 vigor with the saccharifying enzyme that per 1 milliliter of 100000 vigor is measure unit by per 1 gram starch and calculate.
The saccharifying enzyme of the α-Dian Fenmei of required per 1 milliliter of 20000 vigor of using and per 1 milliliter of 100000 vigor can buy on market in the production process.
The present invention adopts alkali enzyme-added in the liquefaction operation, has guaranteed the yield of this technology, is the key point of increasing operation rate.
The present invention adopts neutral method for saccharifying in saccharifying, promptly utilize saccharifying enzyme to carry out saccharification, can reduce investment; simplify technology; equipment is not corroded, but simultaneously in neutral environment the vigor of protective enzyme do not encroached on, lay a good foundation for changing into high-quality glucose.
The present invention compared with prior art has following advantage:
1. equipment is simple, less investment, and technology is simple, and the process-cycle is short.
2. equipment is not perishable, has prolonged the work-ing life of equipment.
3. comprehensive utilization ratio height, the grain transformation efficiency can reach 95%.
4. the glucose quality height of producing, inclusion-free can reach injection glucose standard with comparalive ease.
5. save energy manually expends few.
A most preferred embodiment of the present invention is:
Get main raw material: 750 kilograms of corns, 1500 liters in water.
On market, buy measure unit and be 700 milliliters of the α-Dian Fenmei of per 1 milliliter of 20000 vigor; Measure unit is 2100 milliliters in the saccharifying enzyme of per 1 milliliter of 100000 vigor.
Earlier corn is broken into the powder that granularity is the 0.6-0.8 millimeter, in liquefaction vessel, add Semen Maydis powder and water then, add CaCl simultaneously in 1: 2 ratio
2200 milliliters are evenly stirred with 0.1 ‰-0.5 ‰.700 milliliters of NaOH (proportion is 1.1-1.2), the α-Dian Fenmei (amylase is that per 1 gram starch calculates by 25 vigor) that add 2500 milliliters again; Adjusting the Ph value is about 6.5, and the liquefaction that heats up when temperature reaches 90 ℃, is incubated about 2 hours, and liquefaction finishes.
5000 liters of liquefied product are put into the saccharification container carry out the saccharification processing.In the time of 63 ℃, adjust about Ph value to 5 earlier, evenly stir then, add 2100 milliliters in saccharifying enzyme (per 1 gram starch calculates by 200 vigor) again and transform (saccharification).Treat to transform after 12-24 hour and finish.Inversion rate of glucose can reach more than 94% in the saccharification product.
With pressure filter liquid glucose is separated with slag, requiring can not have foreign matter in the liquid glucose, keeps liquid glucose pure.Handle simultaneously and isolate Zein powder.
Liquid glucose after the filtration needs evaporation concentration to the desired concentration of product, makes the finished product Liquid Glucose.
Produce oral glucose and injectable dextrose monohydrate as desire, need further carry out precision work, its technology is current techique, just promptly carry out secondary press filtration → decolouring → can obtain from friendship → evaporation → crystallization → separation → drying → packing again after aforementioned press filtration operation.
Claims (2)
1. a Semen Maydis powder is produced the glucose making method, and its step is corn → one-tenth powder → liquefaction → saccharification → press filtration → evaporation → various commerieal sugars, it is characterized in that: in the process that liquefies with amylase, add C
aCl (0.1 ‰-0.5 ‰) and caustic soda, the proportion of caustic soda and Semen Maydis powder is 1.1-1.2; In saccharifying, add saccharifying enzyme and carry out saccharification, saccharifying enzymic activity calculates by 200 vigor at 100000 vigor.
2. Semen Maydis powder according to claim 1 is produced the grape manufacture craft, it is characterized in that: the amylase in the liquefaction process is that 20000 unit of activity α-Dian Fenmei are calculated adding by 25 vigor.
