All L*, a*, b* values are presented as mean ± standard deviation. Different lowercase letters indicate a significant difference between different target moisture content at the same screw speed, and different uppercase letters indicate a significant difference between different screw speeds at the same target moisture content (Tukey’s test, p < 0.05).
