The time required for cooking rice is depended on the Gelatinization Temperature (GT) of rice kernel starch (Bhattacharya, 1979; Cruz and Kush, 2000; Singh et al, 2000)

Summary

Introduction

Rice (Oryza sativa L.) is the staple food in Sri Lanka since ancient civilization and it is the main food in most of the other countries in Asia.
