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 122-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.

Reused cooking oil is the oil which is used more than one time and contains less than 25% (by weight) of polar compounds. Degenerative reused cooking oil is the oil which is used more than two times and contains more than 25% (by weight) of polar compounds. Major raw material of fried foods is oil. Therefore usefulness of consumed fried foods depends on the quality of cooking oil. When the oil is heated up while cooking chemical change occurs due to the reactions of hydrolysis oxidation and polymerization. These reactions cause degeneration of the oil i.e. black color rancid smell lower smoke point bubbled increased viscosity and generation of toxic substances called polar compounds. This substance can cause high blood pressure heart disease and coronary artery disease. Furthermore the reused cooking oil also contains polycyclic aromatic hydrocarbons (PAHs) - toxic mutagens which can cause cancer.
