BACKGROUND: Heating temperature is an important factor affecting meat palatability. This study aimed to evaluate the influence of heating temperature on some eating quality indicators, protein degrada...
Isolation of Reaction Products Resulting from Heat-Induced Degradation of Inulin
inulin di-D-fructose dianhydrides DFDA NMR bakery products
2014/3/10
From inulin which had been heated for 30 min at 200°C, four di-D-fructose dianhydrides (DFDAs) were isolated using flash chromatography and final purification by semipreparative HPLC, followed by iden...
Modelling the Effect of Headspace Oxygen Level on the Degradation of Vitamin C in a Model Fruit Juice
oxygen permeability vitamin C fruit juice ascorbic acid dehydro ascorbic acid
2014/3/10
Fruit juices are a significant source of vitamin C in the human diet and therefore their nutritional value is mainly related to the amount vitamin C they contain (KABASAKALIS et al. 2000; MANSO et al....
Plant α-Glucosidase: Molecular Analysis of Rice α-Glucosidase and Degradation Mechanism of Starch Granules in Germination Stage
α-glucosidase starch granules starch granule-binding sit
2008/4/20
In germination of plant seeds, storage starch is principally degraded by the combination of amylolytic enzymes. As starch is an insoluble granule, a conventional view of the degradation pathway is tha...
Properties and Application of Enzymes for Bacterial Glycogen Biosynthesis and Degradation
branching enzyme cyclization dextrin glycogen ADP-glucose pyrophosphorylase
2008/4/20
Structures and properties of enzymes for bacterial glycogen metabolism have been investigated. Branching enzyme (BE, EC 2.4.1.18), which is responsible for α-1,6 glucosidic linkages of glycogen, was f...
Exopolysaccharide Production by Streptococcus salivarius ssp. thermophilus Cultures. 2. Distinct Modes of Polymer Production and Degradation Among Clonal Variants
Streptococcus salivarius ssp.thermophilus mucoid character clonal heterogeneity
2008/3/19
A population of Streptococcus salivarius ssp. thermophilus S22 was clonally heterogeneous in polymer production and the mucoid character of colonies. Weak, moderate, or hyper-producing clones could be...
