The characteristic variables screened of Raman spectroscopic regression modeling of amylopectin content with various rice samples. (a)paddy rice, (b)brown rice, (c)polished rice, (d)rice flour. The blue represents variables exhibiting deviations in Raman characteristic shifts from the established profile of rice amylopectin. The red signifies variables that align closely with the known Raman characteristic shifts of rice amylopectin. The intensity of color correlates with the frequency of variable
