The Cassava and Starch Technology Research Laboratory was established in 1995 through the cooperation of various government agencies, including BIOTEC, Kasetsart University and a private sector body, i.e. the Thai Tapioca Development Institute under the Patronage of HRH Princess Maha Chakri Sirindhorn. The Laboratory is located at the Kasetsart Agricultural and Agro-Industrial Product Improvement Institute of Kasetsart University.

Research Scope

  • Characterization of Cassava and Starch Properties. This research area focuses on characterization of the strengths and weaknesses of cassava starch properties for industrial usage. The characterization of various starches provides a better insight into the correlation between the structural and functional properties of starch, which in turn is vital for developments in its modification and application.
  • Technology Improvements in the Starch Manufacturing Process. This research area focuses on improving the efficiency of starch processing, both in terms of technology and in terms of quality upgrades. This research also extends to the development of techniques for utilizing waste, i.e. cassava pulp from starch extraction process.
  • Development of Starch Modification. This research group aims to improve and alter the properties of cassava starch through a range of modification techniques, whether physical, chemical or biotechnological, with the eventual aim of boosting the value and utilization of cassava starch. 
  • Industrial Application of Cassava and Starch.This research area focuses on the development of cassava and starch applications in both the food and the non-food industries, such as biofuels and bioplastics.


  • Establishment of guidelines for quality control in the cassava starch manufacturing process.
  • Development of a mechanized process for low-cyanide cassava flour production from high cyanide cassava varieties.
  • Production of low protein rice flour by chemical and biotechnical treatment.
  • On-site modification and application of physically modified cassava starch in a noodle factory to replace potato starch.
  • Technology for glucose syrup production from various cassava feedstocks (starch, chips, root and pulp) using enzymatic pretreatment for bio-ethanol application.
  • Establishment of Simultaneous Liquefaction, Saccharification and Fermentation, aone-step non-thermal process technology, based on the enzymatic hydrolysis of uncooked cassava chips and yeast fermentation, for production of ethanol from cassava.
  • Use of a multi-activity enzyme from microbes to obviate the need for high-temperature gelatinization-liquefaction.
  • Development of a process for the production of cassava starch-based hydrogel with properties suitable for a variety of pharmaceutical applications.
  • Production and characterization of cassava starch-based polyglucose, used as an osmotic agent in peritoneal dialysis solution.
  • Development of conjugated-solvent technique for the production of PLA-Starch electrospun nanofibers for pharmaceutical applications.
  • Development of aqueous-based starch composite electrospun nanofibers for pharmaceutical uses.
  • Non-chemical pre-treatment process of cassava for thermoplastic starch production.
