adhesiveness

firmness

Background

This is the second part of the “Gap Testing of a Single Layer of Rice Using TA-40 4” Diameter Cylinder” application study. This study evaluates the reproducibility and differentiation of a gap test on a single layer of rice kernels on four types of Lundberg-brand rice. The rice types were Jasmine, Basmati, Sushi and White Long Grain. The method quantifies the firmness and adhesiveness of rice with the TA.XTPlus Texture Analyzer, Exponent software and a TA-40A 4” diameter cylinder. The test results were very reproducible and were able to highly differentiate the firmness and adhesiveness of the four types of rice under proper cooking conditions as well as when the conditions were intentionally skewed with not enough or too much water.
