Physicochemical, cooking and textural properties of milled rice from different Indian rice cultivars
چکیده انگلیسی
Milled rices from 23 varieties were evaluated for physicochemical, cooking and textural properties. The relationship between different properties was determined using Pearson correlation. Thousand kernel weight, bulk density, length-breadth (L/B) ratio, and amylose content varied between 13.3-19.9 g, 0.77-0.88 g/ml, 2.62-4.55 and 2.3-15.4%, respectively among the various cultivars. Minimum cooking time, water uptake ratio, gruel solid loss, and elongation ratio varied between 13.3-24.0 min, 2.37-4.45, 1.88-8.53% and 1.29-1.74, respectively. Textural properties, such as maximum force, cohesiveness, packability, hardness and chewiness, determined using an Instron Universal Testing Machine varied between 57-266 N, 40-220 N, 10.0-27.0 mm, 20-91 N/mm, and 1505-6969 N mm, respectively. Cooking time showed a negative correlation with amylose content (r=−0.70, p⩽0.01) and a positive correlation with bulk density of milled rice (r=0.333, p⩽0.05). Gruel solid loss showed a significant positive correlation with the amylose content (r=0.880, p⩽0.01) and was negatively correlated with cooking time (r=−0.708, p⩽0.01). The rice cultivars with higher cooking time showed lower gruel solid loss and vice versa. All textural parameters showed a significant correlation with each other and had a positive correlation with amylose and negative correlation with cooking time.
