How often do references need to be measured when using a near infrared diode array spectrometer
(Sage, 2010)
The stability of a diode array spectrometer in the near infrared region has been investigated in two experiments where the frequency of passing of dark and white references, which need manual intervention, was varied. In ...
Optimization of NIR Spectral Data Management for Quality Control of Grape Bunches during On-Vine Ripening
(MDPI, 2011)
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 ...
Monitoring texture and other quality parameters in spinach plants using NIR spectroscopy
(Elsevier, 2018)
Green colour, texture and dry matter are important attributes to appreciate freshness and quality in spinach. However, there is currently no fast, economical and non-destructive method which allows producers to measure ...
Safety and quality issues in summer squashes using handheld portable NIRS sensors for real-time decision making and for on-vine monitoring
(Elsevier, 2019)
BACKGROUND: Portable handheld near infrared spectroscopy (NIRS) instruments currently present enormous advantages in terms of size, weight and robustness. They also provide fast, precise information that can be obtained ...
Setting up a methodology to distinguish between green oranges and leaves using hyperspectral imaging
(Elsevier, 2019)
The estimation of green citrus fruit yield is a key parameter for growers and the industry. The early estimation of orange yield at the immature green stage could influence the future market price and allow producers to ...
Monitoring quality and safety assessment of summer squashes along the food supply chain using near infrared sensors
(Elsevier, 2019)
Currently, there is growing interest from the producers and the vegetable processing industry to use from farm to fork, non-destructive analysis techniques as a routine step to ensure the quality and safety of horticultural ...
Irrigation decision support based on leaf relative water content determination in olive grove using near infrared spectroscopy
(Elsevier, 2019)
The relative water content (RWC) provides a measurement of the water deficit of the leaf and may indicate a degree of stress, endured under conditions of drought and high temperatures. Its measurement is therefore essential ...
LOCAL regression applied to a citrus multispecies library to assess chemical quality parameters using near infrared spectroscopy
(Elsevier, 2019)
The non-destructive on-tree measurement of the chemical quality attributes of fruits belonging to the Citrus genus using rapid spectral sensors is of vital interest to citrus growers, allowing them to carry out a selective ...
A system using in situ NIRS sensors for the detection of product failing to meet quality standards and the prediction of optimal postharvest shelf-life in the case of oranges kept in cold storage
(Elsevier, 2019)
The viability of using near infrared (NIR) spectroscopy was studied as a non-destructive analytical technique with the potential of being applied in situ to establish quality standards and the postharvest shelf-life of ...
Pre-harvest screening on-vine of spinach quality and safety using NIRS technology
(Elsevier, 2019)
The study sought to perform a non-destructive and in-situ quality evaluation of spinach plants using near infrared (NIR) spectroscopy in order to establish its suitability for different uses once harvested. Modified partial ...
