Nir Estimation of Rockmelon (Cucumis Melo) Fruit Tds, in Relation to Tissue Inhomogeneity

NIRS, fruit quality and Central Queensland University

“…Of course, more issues arose, needing solutions, e.g., calibration transfer between instruments 8,9 and the issue of sampling (matching the volume of fruit tissue that was optically sampled with a volume of tissue taken for reference analysis). 10 Another focus was dealing with the impact of varying sample temperatures on water spectra, given the high moisture (80–90% w/w) product content of fruit. 11,12…”
