Description

Based on the starch liquefacation and Mashing process in being produced in fructose

Technical field

The present invention relates to a kind of technique, more particularly, to a kind of starch liquefacation based in being produced in fructose and saccharification work Skill.

Background technology

Contain 6 carbon atoms, and a kind of monose in fructose, be the isomer of glucose, it is a large amount of with free state It is present in the juice and honey of fruit, fructose can also be combined generation sucrose with glucose.Pure fructose is clear crystal, is melted Point is 103~105 DEG C, and it is not easy to crystallize, usually viscous liquid, soluble in water, ethanol and ether.D-Fructose is most sweet tea Monose.Fructose is a kind of most commonly seen ketohexose.It is present in honey, fruit, and glucose is bonded daily consumption Sucrose.Contain 6 carbon atoms, and a kind of monose in fructose, be the isomer of glucose, it largely exists with free state In the juice and honey of fruit, fructose can also be combined generation sucrose with glucose.Pure fructose is clear crystal, and fusing point is 103~105 DEG C, it is not easy to crystallize, usually viscous liquid, soluble in water, ethanol and ether.D-Fructose is the list of most sweet tea Sugar.One kind is refined from various fruit and cereal, the strong new carbohydrate of All Pure Nature, sweet taste, because not being easily caused hyperglycaemia, is not likely to produce Fat accumulation and get fat, will not more produce carious tooth, and recognized by more people.Fructose mainly originates from natural fruit and paddy Among thing, have the advantages that in good taste, sugariness is high, glycemic index is low and be not easily caused carious tooth.The sugariness of fructose is sucrose 1.8 times, be sugariness highest sugar in all natural sugars, so under same sweetness standard, the intake of fructose is only sucrose Half.

Accurately it can not be liquefied and be saccharified during existing fructose production, influence the mouthfeel of fructose, be unfavorable for fructose production.

The content of the invention

Accurately it can not be liquefied and be saccharified during it is an object of the invention to overcome above-mentioned existing fructose production, influence fructose Mouthfeel, be unfavorable for fructose production the problem of, devise a kind of starch liquefacation and Mashing process based in being produced in fructose, should Technique enables to starch fast liquefying and saccharification so that the fructose quality produced is high, in good taste, meets people's demand.

The purpose of the present invention is achieved through the following technical solutions：Based on the starch liquefacation in being produced in fructose and saccharification work Skill, comprise the following steps：

（1）Size mixing and liquefy：Starch is modulated into dry matter content 30%-35% starch milk with water, and pH6.0- is adjusted with hydrochloric acid 6.5, starch material per ton adds ɑ-starch enzyme dosage 6-10 μ/g starch, adds CaCl₂Regulation Ca " concentration reaches 0.01mol/l, Slurry is pumped into Jet liquefier, is instantaneously warming up to 105-110 DEG C, and pipeline liquefaction reaction 10-15min, feed liquid is delivered to liquefied pot, At a temperature of 95-97 DEG C, ɑ-amylase is added twice, continues liquefaction reaction 40-60min, and iodine colour response is qualified；

（2）Saccharification：Liquefied starch introduces saccharifying tank, is cooled to 60 DEG C, adjusts pH to 4.5, adds 80 μ/g diastases, Under the stirring of gap, 60 DEG C of insulation 40-50h, DE ＞ 95 are saccharified to, 90 DEG C is heated up to, carbohydrase is destroyed, are made in saccharification reaction Only；

（3）Saccharified liquid is refined continuously to be filtered using diatomite precoating rotary drum filter, removes the impurity of non-solubility in saccharified liquid And jelly, then the inorganic salts and organic impurities in liquid glucose are removed, are further carried with activated carbon decolorizing, spent ion exchange resin High-purity, liquid glucose is colourless or faint yellow, sugar-containing concentration 24%, and electrical conductivity ＜ 50MS/c, pH4.5-5.0 m, vacuum evaporation is extremely Light transmittance more than 90%, DE value 96-97, sugar concentration are the optium concentration 40%-45% required by isomerase.

In summary, the beneficial effects of the invention are as follows：The technique enables to starch fast liquefying and saccharification so that production The fructose quality gone out is high, in good taste, meets people's demand.
