Abstract:
... Melastoma dodecandrum Lour. (MDL) extracts have shown potent α-glucosidase inhibitory activity, suggesting MDL might be a good source of α-glucosidase inhibitors. The aim of the study was to identify compounds in MDL extracts with α-glucosidase inhibitory activities and evaluate their effect on postprandial blood glucose as well as elucidating the underlying mechanisms of inhibition. A total of 34 ...

Abstract:
... The breakdown of starch into fermentable sugars is essential for several industrial processes, including beer production. Nowadays, high ratios of barley malt to water are used to improve brewhouse efficiency. Recent findings, however, indicate that small starch granules in barley malt could reduce starch conversion efficiency. In this study, the gelatinisation behaviour of small and large starch ...

Abstract:
... Here, we develop a sensitive method for glucose-containing disaccharide analysis by 1-(4-carboxyphenyl)-3-methyl-5-pyrazolone (CPMP) derivatization using mass spectrometry. The intense anion of [M – H]⁻ (m/z 759) was observed for CPMP-labeled disaccharides in a negative mode. After derivatization, its sensitivity was significantly increased with the limits of detection (LODs) and limits of quantif ...

Abstract:
... Microbial enzymes have contributed significantly to the development of biotech based industries over the recent past. Importantly, the microbial α‐amylases share a major market along with proteases. Starch gets hydrolyzed to dextrin, maltotetroses, maltotrioses, maltose, and glucose in trace amount using amylases. To be suitable commercially, the amylase should be stable at higher temperatures and ...

maltose, etc ; emulsions; freeze-thaw cycles; fructose; oil-water interface; sucrose; trehalose; Show all 7 Subjects
Abstract:
... The water-in-oil emulsion transfer method was developed for preparing giant unilamellar vesicles (GUVs) and is useful for studying cellular functions under conditions that mimic cellular environments. A shortcoming of this method for encapsulating biochemical reactions is that it requires high sugar concentrations to enable the density effect to transverse the oil–water interface. In this study, w ...

Abstract:
... Ethyl α-d-glucopyranoside (α-EG) is detected in sake (Japanese rice wine), that has moisturizing and skin conditioning effects. The production of α-EG by fermentation or enzymatic synthesis to date generates unwanted by-products such as maltooligosaccharides and/or organic acids. In this study, we employed a reaction involving selective α-glucosylation of ethanol by the α-glucosyl transfer enzyme ...

Abstract:
... Melibiose, cellobiose, maltose, lactose, turanose, and isomaltulose were selected to be glycated with OVA. The number of free amino groups of OVA modified with different disaccharides decreased, and the secondary and tertiary structures of the modified OVA also changed greatly. Moreover, the glycation sites detected by HPLC–HCD–MS/MS were all on the sensitized epitopes of OVA, which reduced the bi ...

Abstract:
... The dried adductor muscle of scallop (Mizuhopecten yessoensis) has been used as a material for “dashi.” To prepare dashi, the dried scallop must be soaked in water before boiling. Although dashi recipes using dried scallops have been passed down for many generations as a local food, the optimum immersion time prior to cooking has not been elucidated. Thus, the objective of the present study was to ...

Abstract:
... The fermented beverage industry is always pursuing alternatives to make products that delight consumers with special or unique characteristics. The identification and improvement of new yeast strains emerge as an opportunity; however, wild strains usually have a limitation in maltose fermentation and/or off-flavors production. Here we report the production of a Blond-style ale beer using a bioetha ...
