C. Sitakalin et Jfc. Meullenet, Prediction of cooked rice texture using extrusion and compression tests inconjunction with spectral stress strain analysis, CEREAL CHEM, 77(4), 2000, pp. 501-506
Sensory texture attributes of cooked rice from two cultivars (Bengal and Cy
press) harvested in 1997 (56 samples) were predicted using extrusion and co
mpression tests along with spectral stress strain analysis. Predictive mode
ls for each of nine sensory texture attributes studied were evaluated using
force values from the instrumental tests in conjunction with partial least
squares regression. All sensory attributes were well predicted using both
the extrusion and compression tests (relative ability of prediction > 0.70)
. However, the extrusion test consistently provided more accurate and discr
iminative predicted models (root mean square error of prediction < 0.55, S-
tot/RMSEP > 2.0). Spectral stress strain analysis predictive models for adh
esiveness to lips and hardness were explained.
