Attributes measured:

firmness

compression

adhesiveness

stickiness

Background

Rice is a food staple for over 3 billion people in the world. There are plenty of published articles describing methods for evaluating the firmness of cooked rice but no consensus exists between different breeders and researchers. This study presents a compression test with jasmine rice using the TA.XTPlus Texture Analyzer, Exponent software and a TA-40 4” diameter cylinder. The objective is to identify an appropriate sample size, test settings and to present a method that is suitable for determining the firmness and adhesiveness of differently cooked rice. The application then examines the sensitivity of the method by testing rice cooked under different conditions (less water, appropriate amount of water, too much water).
