A near-infrarred reflectance (NIR) equipment with optical based on interfer
ence filters was used. Lineal combination of these filters were obtained fo
r measuring oil content and moisture in olives. A good correlation in the i
nterval 15.70% to 33.00%, between olive oil content predicted by near-infra
rred and data obtained with the Soxhlet method has been obtained (correlati
on coefficient r=0.9908 and estandar error of prediction SEP=0.811). For mo
isture, a good correlation, in the interval 36.5%-65.0% between measures ob
tained by near-infrarred prediction and the reference dry-oven method was a
lso observed (r=0.9939 and SEP=0.928). With a near-infrarred technique meas
urement of both parameter can be takes concurrently and in a few seconds. C
hemical reagents and complex sample preparation are not required, only mill
ing of drupes by a hammer crusher.
