Multiple strategies for heat adaptation to prevent chalkiness in the ...
WEBFeb 1, 2019 · This study revealed the cellular dynamics for heat-induced chalky formation and nitrogen-enhanced heat adaptive mechanism by conducting a newly developed on-site cell-specific analysis coupled with time-course analysis via microscopy.
Relationship between High Temperature and Formation of …
WEBApr 1, 2018 · The percentage of chalkiness in rice grain is an index that determines the appearance quality. Chalky grains were found to contain a lower density of starch granules as compared to vitreous ones . So, for improving the milling and cooking quality, rice endosperm should be free from chalkiness.
Physico-chemical, morphological, thermal, cooking and textural ...
WEBAug 1, 2003 · Chalky grains showed higher transition temperatures, enthalpy of gelatinization, peak height index and gelatinization range than the translucent grains. The cooking and textural properties of chalky and translucent kernels differed significantly.
Characteristics of Physicochemical Properties of Chalky Grains …
WEBAbstract. Global warming has caused devastating damage to starch biosynthesis, which has led to the increase in chalky grains of rice. This study was conducted to characterize the qualities of chalky rice grains and to develop the estimation formulae for their quality damage degree.
Starch molecular structural differences between chalky and …
WEBNov 15, 2022 · In rice grains, starch is the main component (up to ∼ 90% of dry weight). Thus, starch structural analysis may give information on the chalkiness formation by revealing any differences in the starch molecular fine …
Detection of chalk in single kernels of long‐grain milled rice …
WEBSep 14, 2019 · An objective technique to detect grain chalk, opaque areas in the grain, will provide breeders and industry with an effective tool for developing low-chalk varieties or agronomic practices that reduce chalk occurrence.
Fine structures and physicochemical properties of starches from chalky …
WEBApr 23, 2003 · This work compared the molecular structures and physicochemical properties of starches obtained from chalky and translucent kernels of six rice cultivars. Starch samples were prepared according to a modified alkali steeping method.

WEBJul 20, 2018 · The occurrence of chalky kernels in rice is causally related to kernel size and endosperm morphology. This study aimed to investigate the occurrence of chalky kernels by analyzing kernel size, and the number and area of endosperm cells.
Physicochemical Characteristics of Chalky Kernels and Their …
WEBThe chalky kernels tended to be smaller in kernel area, maximum diameter, minimum diameter, and perimeter than vitreous kernels. Amylose content in chalky kernels was slightly lower than that in vitreous kernels. WAI of chalky kernels was higher than that of vitreous kernels.
Evaluation and analysis the chalkiness of connected rice kernels …
WEBSep 1, 2014 · Image processing technology was applied to the separation of chalky rice kernels, and was found to be very effective for two to five connected kernels. The suspected chalky areas were extracted from endosperm according to different grayscale levels and were classified using SVM.
