Regression equations for physical properties of soy protein isolate-corn starch blend
extrusion (taking significant parameters on the basis of t > 2.5 at probability level
p 0.05). [BS ¼ breaking stress, BD ¼ bulk density, ER ¼ expansion ratio,
WSI ¼ water solubility index, RR ¼ rehydration ratio, L ¼ lightness (L, a, b color
space)].
