Determination of Oil Content in Whole Milk Thistle Seeds Using Fourier Transform near – Infrared (ft – Nir) Spectroscopy
ثبت نشده
چکیده
Our objective was to create a calibration model for rapid determination of the oil in whole Milk Thistle seeds using the method Fourier Transform Near Infrared (FT-NIR) Spectroscopy. The seeds from different distributors and dealers from several European countries and from the harvests 2010, 2011 and 2013 were processed by Soxhlet extraction in Det-Gras N instrument and its FTNIR spectra were collected. The calibration model was created using Partial Least Square (PLS) chemometric analysis – and was successfully tested with the validation samples (spectra not included in the calibration model).

Rapid Determination of Active Compounds and Antioxidant Activity of Okra Seeds Using Fourier Transform Near Infrared (FT-NIR) Spectroscopy.
Okra seeds (OSD) have been proved to possess significantly anti-fatigue activity and due to their high contents of flavonoids and polyphenols. While, the quality of OSD is easily affected by harvest time, region and other factors. In this research, the rapid method based on Fourier transform near infrared (FT-NIR) spectroscopy was developed for quality assessment of okra seeds. Firstly, 120 sam...
متن کاملMeasurement of Soy Contents in Ground Beef Using Near-Infrared Spectroscopy
Models for determining contents of soy products in ground beef were developed using near-infrared (NIR) spectroscopy. Samples were prepared by mixing four kinds of soybean protein products (Arconet, toasted soy grits, Profam and textured vegetable protein (TVP)) with ground beef (content from 0%–100%). NIR spectra of meat mixtures were measured with dispersive (400–2500 nm) and Fourier transfor...

Nondestructive method of measuring the internal quality of citrus fruits was developed using fourier transform near-infrared (FT-NIR) spectroscopy. Also the models describing the relationship between quality attributes and the NIR spectra of the fruits were developed and evaluated. Diffuse reflectance measurements (12500–3600 cm -1 ) and biochemical measurements were performed individually on e...
