A process for converting starch or partially hydrolyzed starch into a syrup containing dextrose includes the steps of saccharifying starch hydrolyzate in the presence of a mutated glucoamylase or related enzyme and increasing the selectivity of the enzyme for α-(1←4)-glucosidic bonds by the ...
Any of numerous compounds that are produced by living organisms and function as biochemical catalysts. Some enzymes are simple proteins, and others consist of a protein linked to one or more nonprotein groups. [GermanEnzym, from Medieval Greekenzūmos,leavened: Greeken-,in; seeen-2+ Greekzūmē...
The effect of heat treatment below the gelatinization temperature on the susceptibility of corn, mung bean, sago, and potato starches towards granular starch hydrolysis (35°C) was investigated. Starches were hydrolyzed in granular state and after heat treatment (50°C for 30min) by using granular...
ELECTROLYTES IN STARCH STRUCTURE AND THEIR BEHAVIOUR IN THE HYDROLYSIS OF STARCH BY BARLEY AND MALT AMYLASES From a study of starch liquefaction and saccharification, chiefly with malt amyiase, the actions of a liquefying and a saccharifying enzyme may be ... C Le,H. - 《Journal of the In...
For the complete breakdown of starch into its monosaccharide other enzymes called glucoamylases are required. The most widely used glucoamylases for complete hydrolysis of starch into glucose are produced by a fungal strain of the genus Aspergillus (Sonenshein et al., 1993). Overproducing strains ...
The coupled transglycosylation and hydrolysis activities of maltogenic amylases [20] have been used to produce IMOs from liquefied starch in a more efficient way than the conventional three-step process, resulting in a significant increase in the maximum yields of IMOs. Further improvement of IMO ...
Effect of pretreatment severity on the enzymatic hydrolysis of bamboo in hydrothermal deconstruction Bamboo was subjected to hydrothermal deconstruction to release xylans for the enhancement of enzymatic hydrolysis. The de-waxed and de-starched bamboo culm... MF Li,CZ Chen,RC Sun - 《Cellulose》 被...
Porous starch granules were formed by the partial hydrolysis of starch using amylase. Fungal amylase and corn starch were chosen as the original amylase an... J Qian,X Chen,X Ying,... - 《International Journal of Food Science & Technology》 被引量: 32发表: 2011年 Study on Preparation and...
Starch hydrolysis is an important feature of starch function both in the plant and when the plant is used for human food. Hydrolysis of starch ingested as food can vary both with respect to the rate and the extent of digestion by pancreatic α-amylase. In the human digestive tract, the un...
Chitinase, an enzyme driving the hydrolysis ofchitin, is present in the digestive system of many species regardless of their feeding habits, with different optimal pH and tissue distribution. Chitin, a linear homopolymer ofN-acetylglucosamine (NAG) units linked by β(1→4)-glucosidic bonds, is ...
