This invention provides a method for identifying the textural characteristics of small-sample cooked rice from rice genetic populations. By using centrifuge tubes as the rice cooking vessel and measuring various textural parameters of the rice using a texture analyzer, the amount of each parallel sample is reduced to 0.5 ± 0.03 g. Only 2.5 g is needed to obtain the textural parameters of both fresh and reheated rice, providing a feasible method for identifying the textural phenotype of rice genetic populations, especially those with small seed quantities. Qualitative medium-speed filter paper is used to cover the tube opening, facilitating the exchange of moisture between the inside and outside of the centrifuge tube during cooking and preventing rapid loss of surface moisture during reheating. The sampling process employs whole-grain indiscriminate sampling, effectively avoiding differences in results caused by different sampling locations due to the unevenness of the inner and outer layers of the rice when sampling from a large number of samples after cooking. This invention establishes an objective evaluation method for the textural characteristics of small-sample rice based on a texture analyzer, laying the foundation for genetic research on the textural characteristics of rice.
