Research on diet selection is limited by inadequate techniques for determining botanical composition of diets. Our objective was to determine if near infrared reflectance spectroscopy (NIRS) of fecal material could be used to quantify the percentage leafy spurge (Euphorbia esula L.) in the diets of sheep (Ovis aries) and goats (Capra hircus). Fecal material representing diets of known percentag...

Visible/Near-infrared reflectance spectroscopy (Vis/NIRS) was applied to variety discrimination of juicy peach. A total of 75 samples were investigated for Vis/NIRS using a field spectroradiometer. Chemometrics was used to build the relationship between the absorbance spectra and varieties. Principle component analysis (PCA) was executed to reduce numerous wavebands into 8 principle components ...

Near infrared spectroscopy (NIRS) is a noninvasive optical technology that relies on the relative transparency of biological tissues to near infrared light (700-900 nm) to determine tissue oxygenation. Oxy and deoxy hemoglobin and cytochrome aa3 possess distinct absorption characteristics in the near infrared spectrum. By monitoring absorption at wavelengths where oxyand deoxyhemoglobin and cyt...

Rapeseed protein consists mainly of the seed storage cruciferin and napin. Cruciferin napin have different nutritional values techno-functional properties. Shifting cruciferin/napin ratio towards either more or could allow diversified applications. The objective this study was to investigate genetic variation in modern winter rapeseed cultivars. contents were analysed by SDS-PAGE. Genetic for b...

The development of NIRS calibration model as a rapid, precise, robust, and cost-effective method to estimate oil content in ground seeds of worldwide safflower germplasm collection grown under different agro-climatic conditions was the key objective of this research project. The oil content was measured by accelerated solvent extraction method in a total of 328 samples collected across 2004 (16...

The estimation of nitrogen status, non-destructively, in oilseed rape was performed using spectral reflectance with visible and near infrared reflectance spectroscopy (Vis/NIRS), and SPAD values of the oilseed rape leaves of 30 plots were measured by a SPAD 502 chlorophyll meter, and the research was carried out at experiment field in the Zhejiang University during growing season from 2007 to 2...

Abstrak: Minyak nilam adalah salah satu produk yang banyak diekspor oleh Indonesia. Banyak terjadi kecurangan-kecurangan dalam dunia perdagangan minyak atsiri jenis ini, satunya pemalsuan. Tujuan dari penelitian ini untuk membangun model keaslian dicampur dengan goreng sawit kemasan menggunakan teknologi NIRS (Near Infrared Reflectance Spectroscopy) bantuan metode Linear Discriminant Analysis (...
