Description
Technical field
The present invention relates to a kind of instant instant xylitol preparation method, belong to technical field of functional sugar alcohol production.
Background technology
Xylitol, i.e. pentitol, contain the material of pentosan for raw material with corncob, bagasse, cotton seed hull, birch etc., through the white crystal that the operations such as hydrolysis, purification, hydrogenation, concentrated, crystallization, centrifugal, oven dry are obtained, it is soluble in water, sugariness is suitable with sucrose, and edible, entrance has refrigerant sense.
Xylitol also has special biochemical property, if do not needed directly to be absorbed by the body by cell membrane by insulin, has the function reducing blood fat.It can also regulate the pH value of cavity gum and the fermentation of antagonism oral microorganism in addition, there is special preventing decayed tooth function, the such as chewing gum of our often use, our fresh breath can be helped, but often chew gum the material that can damage for dental filling in oral cavity, mercury alloy is wherein discharged, causes the mercury content in blood, urine to exceed standard, thus brain, nervous centralis and kidney are worked the mischief.Again, chew gum unfavorable to children, because children's self-control is poor, chews gum likely to cause and eat or be strayed into tracheae, threat to life.In addition, chew gum for a long time, masseter is in tension all the time, likely causes the bad habit of sleeping and grinding one's teeth in sleep, affects sleep quality.Therefore, xylitol being made a kind of instant instant food is very favorable for human body.
The production technology of current xylitol is still based on chemical method, be generally the string being rich in pentosan be raw material, wood sugar is obtained through steps such as hydrolysis, purifying and ion-exchanges, such as patent publication No. is CN1903866A, what name was called that " a kind of preparation method of crystalline xylosic alcohol powder " adopt is exactly the method, but the sewage produced in process of production is many, severe contamination environment, and also wood sugar yield is lower.
Summary of the invention
The technical problem that the present invention mainly solves: the chewing gum made for current xylitol easily causes masseter pull and be detrimental to health when chewing, chew tasteless after the residue environmental pollution that spues seriously be difficult to cleaning, and the sewage produced in process of production is many, the drawback that wood sugar yield is also lower, provide a kind of instant instant xylitol preparation method, be raw material by agricultural residues such as maize pulps, pass through pretreatment, hydrolysis, hydrogenating reduction, concentrated, crystallization, the serial of methods such as centrifugal, thus obtain clean xylitol crystal, and utilize cotton candy machine to be made into cotton candy xylitol crystal, thus make a kind of instant instant xylitol.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
(1) get 50 ~ 100g corncob, 70 ~ 120g sugarcane, 80 ~ 125g cotton seed hull, squeeze add 300 ~ 500ml clear water after water with squeezer, be uniformly mixed;
(2) in mixed liquor, add 5 ~ 10g peppermint, 3 ~ 5g gas-producing disintegrant, fully mix, cause dissolving;
(3) according to the corncob after process, sugarcane, 2 ~ 3 times of cotton seed hull dry weight add the hydrochloric acid solution that mass concentration is 0.5mol/L, it is 100 ~ 120 DEG C that temperature controls, and obtains xylose hydrolysis fluid after hydrolysis 3 ~ 4h;
(4) be injected into and be equipped with in the hydrogenation reaction kettle of Ni-Al alloy catalyst by the xylose hydrolysis fluid after hydrolysis, controlling hydrogenation temperature is 120 ~ 150 DEG C, and pressure is 15 ~ 18MPa, makes xylose hydrolysis fluid be converted into xylitol liquid;
(5) evaporimeter is utilized to be 80 ~ 85% by xylitol liquid evaporation and concentration obtained above to mass concentration;
(6) be put in round powder hybrid junctions crystal by the xylitol liquid after concentrated, the temperature of mixed liquor is cooled to 80 ~ 100 DEG C, then sprays into 10 ~ 20g xylitol crystal, cools while stirring, makes xylitol crystal constantly grow and separate out;
(7) put in centrifuge by xylitol crystal, centrifugal 2 ~ 3h, rotating speed is after 1200 ~ 1500r/min, xylitol crystal is separated with mother liquor, obtains clean xylitol crystal;
(8) utilize cotton candy machine that xylitol is made into cotton candy.
Described cotton candy making step is:
(1) get ready xylitol crystal 10 ~ 20g, and put it in cotton candy machine with little spoon;
(2) after sugared silk flies out, a hand-held bamboo let turns clockwise, and keeps hand-held bamboo let to balance, and keeps low early and high after mobile status, be wound into equably on bamboo let by sugared silk in winding process.
The invention has the beneficial effects as follows:
(1) xylitol is made cotton candy, do not need to chew, old man and child's use safety;
(2) utilize agricultural residue for raw material, twice laid, save cost;
(3) manufacture craft is simple, operates easy.
