Abbreviations: TS, tapioca starch; CS, corn starch; PS, pea starch; L*, lightness; a*, redness; b*, yellowness
^cThe P values indicate the effects of different dietary starch sources with different amylose/amylopectin ratios by one-way ANOVA and polynomial contrasts- linear and quadratic analyses, respectively
