Pear quality characteristics by Vis / NIR spectroscopy

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...

nondestructive 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...

Noninvasive Tissue Monitoring Using UV-Vis and NIR Spectroscopy

the key to many studies into the efficacy and impact of ingested and topical drugs affecting pigmentation. Spectral reflectance measurements offer an objective way to measure skin throughout dermatological studies, providing quantitative data on color and absorbance of skin. Ocean Optics modular products offer the flexibility to design a measurement system for a wide variety of dermal studies, ...

Nir and Vis-nir Spectroscopy to Predict Pse-like Zones of Ham

The aim of the study was to evaluate NitFom ́s ability to predict PSE-like zones, a muscle structure defect in ham, which at present can only be detected by visual inspection after deboning. NitFom is an on-line fast device based on NIR spectroscopy dedicated to the meat industry. In comparison with the Vis-NIR Labspec4 spectrometer, the overall misclassification level of the NitFom is higher (1...
