Description

One.Product presentation Middle-temperature-amylase is extracted from fermented deeply Bacillus ***** can hydrolyze starch and hepatin, dissolve internal Alpha*1, 4 glucose glycosidic linkage, produce short-chain dextrine and oligosaccharide to reduce viscosity of gelatineous starch ***** enzyme can be used in beer brewing, alcohol production, monosodium glutamate, starch sugar, feed, liquefication of fermentation business, fiber, printing and dyeing, etc. Two. Product specification and qanlity index Item Index Item Index Appearance Light-yellow powder Brown liquid Temperature ****0℃ Activity u/ml(g) ***0、***0、***0、***0 Best temperature *0℃ Smell No irritative smell Water concent ï&frac*4;œ8% pH range 5.**7.0 *0mesh ≥*0% Best pH 6.**6.4 Volume weight ≤1.*5g/ml Three.Define of enzyme activity In the condition of *0 centi grade, PH6.0, the amount of this enzyme it needs which dissolved starch become dextrine in one ***** is an enzyme activity. Four.Using methods 1. In the process of beer brewing, this enzyme can be added after material is stired in the mash ***** material can need 6 unit enzyme The material can be liquefied about *0 mins in ****0 centi grade. 2. In the process of sugar and monosodium glutamate, this kind of starch enzyme can be added to starch slurry(**8 unit per gram material), and they are sufficiently mixed, you can heat them to ****0 centi grade and liquefy them about *0 mins. 3. In the process of textiles desizing, it can be used in desizing of no resisting high-temperature silk, chemical fiber, ***** addition of this enzyme is 0.2 percent(****0u/ml), and it should be kept ****0 mins after the temperature is increased to ****0 centi grade. 4. In other industries, the addition of enzyme can be controled in **8 unit per gram starch, and concentration of Ca is **0 ppm. Five.Package and storage The package of liquid is innoxious plastic ***** inside pack of powder is innoxious plastic bag(1kg per bag), and extrenal pack of powder is paper box(*0kg per box). This product is active bio-substance, which is avoided strong sunshine and high ***** should be put on cool and dry place.
