ABSRACTFactors influencing the color of liquid‐cyclone‐process (LCP), gland‐less and gland‐free cottonseed flours were investigated. Among the factors considered were variation in pH, heat, presence or absence of pigment glands and hull contents. It is apparent that all the factors studied here contribute to the discoloration of the cottonseed product to a certain degree.

The extra glandular pigments only show some influence on the colour of cottonseed products at alkalinic con
