For starch digestion to glucose, two luminal a-amylases and four gut mucosal a-glucosidase subunits are employed. The aim of this research was to investigate, for the first time, direct digestion capability of individual mucosal a-glucosidases on cooked (gelatinized) starch. Gelatinized normal maize starch was digested with Nand C-terminal subunits of recombinant mammalian maltase-glucoamylase ...

Cyclodextrin glucanotransferase (CGTase, EC 2.4.1.19) is an important member of α-amylase family which can degrade the starch and produce cyclodextrins (CDs) as a result of intramolecular transglycosylation (cyclization). β-Cyclodextrin production was carried out using the purified CGTase enzyme from an alkaliphile Microbacterium terrae KNR 9 with different starches in raw as well as gelatinize...

The traditional use of sodium chloride (NaCl) fulfils various important rheological, technological and sensory properties while manufacturing of baked goods. However, using NaCl in the production of food has been controversially discussed since a high intake of sodium is discussed to be associated with hypertension. Retrogradation of starch in bread crumb is defined for changes that take place ...

A standard resin system used in wood-based panel preparation was formaldehyde-based glue, which believed to have fatal effects on the environment and human health due release of free formaldehyde. Therefore, study's objective evaluate physical mechanical properties experimental plywood made using glutardialdehyde-modified starch as an environmentally friendly binder. Two gelatinization methods ...

This chapter evaluates and compares the indoor performance of different concentrations non gelatinized starch in drilling fluid, modified at 80°C, then aged high temperature. Taking plastic viscosity (PV) filtration loss (FL) as main evaluation indexes, a formula with better was selected additive used follow-up study. At same time, inhibition water-based fluid investigated.

Sorghum (Sorghum bicolor (L.)Moench) is a starch-rich grain similar to maize (Zea mays L.), but sorghum has been underutilized for biobased products and bioenergy. This study was designed to investigate the effects of supercritical-fluid-extrusion (SCFX) of sorghum on ethanol production. Morphology, chemical composition, and thermal properties of extruded sorghum were characterized. Analysis of...
