a non-destructive, rapid and low-cost determination of date fruit moisture content is one of the most determining factors in maturity assessment and processing of this valuable product. on the other hand, the potential of near infrared (nir) spectroscopy in nondestructive internal quality evaluation of agricultural products has been proved throughout several studies. in this research, three mod...

BACKGROUND Lean body mass (LBM) is an important nutritional measure representing muscle mass and somatic protein in hemodialysis patients, for whom we developed and tested equations to estimate LBM. STUDY DESIGN A study of diagnostic test accuracy. SETTING & PARTICIPANTS The development cohort included 118 hemodialysis patients with LBM measured using dual-energy x-ray absorptiometry (DEXA)...

A new method for the estimation of body composition in humans, called infrared interactance, is discussed. Infrared interactance is based on the principles of light absorption, reflection, and near-infrared spectroscopy. Body composition (percentage fat) was estimated in 53 adults (23 to 65 yr of age) by infrared interactance and compared to results from deuterium oxide dilution (r = 0.94), ski...

Three modes of visible-near infrared spectroscopic measurement (reflectance, interactance and transmission) were compared for their ability to non-destructively estimate harvest soluble solids content (SSC), density and internal flesh colour of the yellow-fleshed kiwifruit Actinidia chinensis. Interactance mode spectra provided the most accurate estimates of SSC, density and flesh colour. SSC w...

This study presents a novel application of near infrared (NIR) spectral linearisation for measuring the soluble solids content (SSC) of carambola fruits. NIR spectra were measured using reflectance and interactance methods. In this study, only the interactance measurement technique successfully generated a reliable measurement result with a coefficient of determination of (R2) = 0.724 and a roo...
