Abstract
The effects of different isolation methods including drymilling DM sour liquid processing SL alkaline steeping AS and neutral protease isolation NP on pea starch physicochemical properties and textural properties of vermicelli were studied The results showed that the pea starch isolated by DM had higher damaged starch content of 1244 The starch isolated by NP showed the lowest SP and SOL while DM starch showed the highest The AS starch showed higher PV TV and FV than the other starches The NP starch gel showed significantly lower hardness value than the other starch gel The AS starch had higher To Tp Tc and endothermic enthalpy value than SL starch did The vermicelli made from NP and SL starches had significantly lower CL and higher tensile strength elongation at break apparent modulus and fracture work The result of the study implied that the vermicelli made from NP and SL starches had better quality than that made from DM and AS starches
