The color of the uncooked and cooked noodle samples were measured with spectrophotometer (Hunter Lab,
Color Quest XE, USA) equipped with a D65 illuminant using the CIE L* a* b* system. L* value is a measurement
of brightness (0-100); a* value represents the red – green coordinates (- is green while + is red); b* value indicates
the blue – yellow coordinates (- is blue while + is yellow). All measurements were performed in triplicate.
