A Guide to Raw Material Analysis using Fourier Transform Near-Infrared Spectroscopy
• Spectral Libraries In this document, we discuss the principles behind the planning, development and implementation of Fourier transform near-infrared (FT-NIR) spectroscopic libraries for raw material identification and qualification. This document considers not only the mechanics of library construction but also the steps in establishing a raw material program. This includes the planning stag...
متن کاملApplications of Near Infrared Spectroscopic Analysis in the Food Industry and Research
Near infrared spectroscopy (NIR) is routinely used in agriculture, for the analysis of pharmaceuticals, combustion products, astronomy, food stuffs and in research. The method has been broadly accepted and is widely used in quality assessment of foods, beverages and in food and beverage research. The method is relatively inexpensive, rapid, preserves the sample and is able to measure several co...
متن کاملNear-infrared calibration transfer based on spectral regression.
A calibration transfer method for near-infrared (NIR) spectra based on spectral regression is proposed. Spectral regression method can reveal low dimensional manifold structure in high dimensional spectroscopic data and is suitable to transfer the NIR spectra of different instruments. A comparative study of the proposed method and piecewise direct standardization (PDS) for standardization on tw...
متن کاملPrediction of Freshness Quality and Phosphate Residue of White Shrimp Products Using Near-Infrared Spectroscopy
Background: The manufacturing of frozen shrimp is an important industry for the economy of Thailand. The objective of this study was to use Near-Infrared (NIR) spectroscopy to determine the freshness quality, including Total Volatile Basic Nitrogen (TVB-N) and Water Holding Capacity (WHC) of white shrimp (whole and chopped shrimp) and phosphate residues of shrimp. Methods: Sixty white shrimp ...
متن کاملComparison and combination of spectroscopic techniques for the detection of counterfeit medicines.
During this study, Fourier transform infrared spectroscopy (FT-IR), near infrared spectroscopy (NIR) and Raman spectroscopy were applied to 55 samples of counterfeit and imitations of Viagra and 39 samples of counterfeit and imitations of Cialis. The aim of the study was to investigate which of these techniques and associations of them were the best for discriminating genuine from counterfeit a...
