Abstract
Purpose
The purpose of this paper is to examine descriptive sensory characteristics and consumer acceptability of eight commercial ready-to-eat cooked rice samples by 8 trained panelists and 50 consumers.
Design/methodology/approach
A total of 24 descriptive attributes for appearance, odor/aroma, taste/flavor, and texture were developed. Also Consumer Acceptability (CA) was performed for overall liking, appearance, flavor, and texture liking. All statistical analyses were using analysis of variance, principal component analysis (PCA), hierarchical cluster analysis (HCA), and partial least square regression (PLSR).
Findings
The overall liking score for the cooked white rice from C brand was the highest (6.43) among the eight samples. Three groups of eight commercial ready-to-eat cooked rice samples were obtained from PCA and HCA. The samples of cooked white rice from C, N, and O brand characterized by intactness, starch odor, translucency, whiteness, and glossiness were located on to the positive PLS 1, whereas the samples of cooked white rice from D and E brand characterized by scorched odor, cohesiveness, stickiness, and moistness were located on the negative side of PLS 2 in the PLSR analysis.
Originality/value
Further studies on the improvement of sensory quality for brown rice are necessary to increase CA in terms of health functionality of brown rice.
