Mechanical Texture Measurement of Whole and Chopped Peanuts¹

Abstract

Different test cells (a Warner-Bratzler type blade, compression cell and a modified Kramer shear-compression cell) were compared to obtain an objective method for texture measurement of whole and chopped peanuts. The modified Kramer shear-compression cell was found to be the most sensitive in measuring textural characteristics of whole peanuts. Objective parameters, force and energy, correlated well with subjective parameters resulting from sensory evaluation, crispness and crunchiness (r² = 0.77 and 0.79), respectively. The coefficients of determination (r²) between whole and chopped peanuts for force and energy were 0.81 and 0.72, respectively; which suggested that the modified Kramer shear-compression cell can be used to evaluate the textural quality of chopped peanuts.
