Journal ArticleDOI
Porous high amylose rice starch modified by amyloglucosidase and maltogenic α-amylase
Thewika Keeratiburana,Aleksander Riise Hansen,Siriwat Soontaranon,Andreas Blennow,Sunanta Tongta +4 more
TL;DR: The results demonstrate that porous rice starch can provide different functionalities depending on the enzyme mechanisms, extending the range of applications.
Journal ArticleDOI
Generation of short-chained granular corn starch by maltogenic α-amylase and transglucosidase treatment.
Yuyue Zhong,Thewika Keeratiburana,Jacob J. K. Kirkensgaard,Bekzod Khakimov,Andreas Blennow,Aleksander Riise Hansen +5 more
TL;DR: The potential of sequential addition of starch active enzymes to obtain granular starch with improved functionality is demonstrated to be sequential after the pre-treatment by maltogenic α-amylases from GH13.
Journal ArticleDOI
Porous rice starch produced by combined ultrasound-assisted ice recrystallization and enzymatic hydrolysis.
Thewika Keeratiburana,Thewika Keeratiburana,Aleksander Riise Hansen,Siriwat Soontaranon,Sunanta Tongta,Andreas Blennow +5 more
TL;DR: This study demonstrates that US+IR treatment in combination with enzyme hydrolysis is a useful method to produce specifically functionalized porous rice starch that can be used as e.g. absorbents and for further chemical modifications.
Journal ArticleDOI
Pore characteristics and structural properties of ethanol-treated starch in relation to water absorption capacity
Achmat Sarifudin,Achmat Sarifudin,Thewika Keeratiburana,Siriwat Soontaranon,Chaiyot Tangsathitkulchai,Sunanta Tongta +5 more
TL;DR: In this paper, the pore characteristics and structural properties of ETS prepared from four different starch sources (maize, potato, cassava, and rice starches) at three conversion temperatures (80, 90 and 100°C) were investigated.
Journal ArticleDOI
Pre-treatment of granular rice starch to enhance branching enzyme catalysis
Thewika Keeratiburana,Aleksander Riise Hansen,Siriwat Soontaranon,Andreas Blennow,Sunanta Tongta +4 more
TL;DR: Pre-treatment prior to BE catalysis offers an efficient alternative way to modify granular starch with different structure and properties depending on the pre-treatment protocol.
