The dominant feature of khao wong glutinous rice kalasin province for geographical indications

Abstract

The objective of this research was to study the dominant feature of Khao Wong glutinous rice Kalasin province for geographical indications. The effect of three cultivated areas of glutinous rice variety (RD6) consisting of Khao Wong, Huai Mek and Kong Chai districts was investigated along with their physicochemical textural properties and thermal properties. For the effect of different cultivated areas on glutinous rice properties, the significant effect of different cultivated areas on chemical compounds, viscosity and textural properties was observed (p?0.05). There was no significant effect of cultivated areas on amylose content (p>0.05). The highest protein and ash contents and the lowest setback, hardness and chewiness values were found in the sample cultivated in Khao Wong district area. The aroma compounds analysis of rice samples revealed that methanecarboxylic acid was observed in glutinous rice cultivated in all studied areas. Whereas, the highest content of 1,2,2-Trimethylcyclopropylamine was found in the sample cultivated at Khao Wong and Kong Chai districts. In addition, the highest content of 2-cis-9-octadecenyloxyethanol was observed in glutinous rice cultivated at Huai Mek district.
