Pear quality characteristics by Vis / NIR spectroscopy.
Recently, non-destructive techniques such as the Vis / NIR spectroscopy have been used to evaluate the characteristics of maturation and quality of pears. The study aims to validate the readings by the Vis / NIR spectroscopy as a non-destructive way to assess the qualitative characteristics of pear cultivars 'Williams', 'Packams' and 'Carrick', produced according to Brazilian conditions. The ex...
متن کاملWood quality assessment of tree trunk from the tree branch sample and auxiliary data based on NIR Spectroscopy and SilviScan
We estimated wood quality parameters for a specific tree trunk using samples of this tree’s branch, and auxiliary samples from other similar species, based on analysis of wood density, modulus of elasticity (MOE), and microfibril angle (MFA), measured with the near-infrared spectroscopy (NIRS) and SilviScan processes. The measured materials included a branch sample from the subject tree, also k...

متن کاملnondestructive evaluation of internal quality characteristics of kiwifruit by vis/nir spectroscopy
abstract the assessment of ripeness is a major part of quality evaluation and depends on several factors such as soluble solid content (ssc), acidity and firmness. most of the methods that measure these qualities are destructive. so it is essential to develop an efficient and nondestructive method for measuring internal attributes of fruit. the objective of this study was to investigate visible...
متن کاملNIR Spectroscopy of Actaea racemosa L. rhizome - En Route to Fast and Low-Cost Quality Assessment.
Rhizomes of Actaea racemosa L. (formerly Cimicifuga racemosa) gained increasing interest as a plant-derived drug due to its hormone-like activity and the absence of estrogenic activity. According to the Current Good Manufacturing Practices guidelines and pharmacopeial standards, quality assessment of herbal starting materials includes tests on identity and substitution, as well as quantificatio...
