Optimization of NIR Spectral Data Management for Quality Control of Grape Bunches during On-Vine Ripening
NIR spectroscopy was used as a non-destructive technique for the assessment of chemical changes in the main internal quality properties of wine grapes (Vitis vinifera L.) during on-vine ripening and at harvest. A total of 363 samples from 25 white and red grape varieties were used to construct quality-prediction models based on reference data and on NIR spectral data obtained using a commercial...
متن کاملA revolutionary device for predicting grape maturity based on NIR spectrometry
Near Infrared spectrometry can be used for measuring the evolution of fruit quality traits. The main characteristics that can be measured are sugar content but also in some case acidity. In conjunction with IFV (institute of Vine and wine), Cemagref research centre and Pellenc SA company have conducted long term researches to get accurate measures of grape sugar and acidity in field conditions,...
متن کاملGrape Maturity
Berry sensory analysis (BSA) follows a standardized set of 20 descriptors, assessing the ripeness of wine grapes by judging fruit stems, skin, pulp, and seeds separately (Winter et al., 2004). It uses a four-point scoring system to determine relative ripeness and the change in ripeness over time. As with any maturity analysis, this system is most advantageously used in conjunction with other as...
متن کاملA Contactless Technique for Measuring Minority-carrier Parameters in Silicon
Characterization of minority-carrier parameters is a primary interest for a range of devices, including solar cells. For “on-line” testing needs, contactless techniques are mandatory, as any diagnostic requiring contact formation is impractical. Here, we will describe the resonancecoupled photoconductive decay (RCPCD) technique that has proven to be a valuable diagnostic for a number of semicon...
متن کاملContactless electromagnetic measuring system using conventional calibration algorithms to determine scattering parameters
In this paper, a contactless measuring system for the determination of the S-parameters of planar circuits is presented. With a contactless measuring system it is possible to characterise a device-under-test (DUT) embedded in a planar circuit environment without cutting the planar transmission lines connecting the DUT. The technique utilizes four identical capacitive probes in conjunction with ...
