Sulfur-fumigated Chinese medicine is a common issue in the process of Chinese medicines. Detection of sulfur dioxide (SO 2 ) residual content in Fritillaria thunbergii Bulbus is important to evaluate the degree of sulfur fumigation and its harms. It helps to control the use of sulfur fumigation in Fritillaria thunbergii Bulbus. Near-infrared hyperspectral imaging (NIR-HSI) was explored as a rapid, non-destructive, and accurate technique to detect SO 2 residual contents in Fritillaria thunbergii Bulbus. An HSI system covering the spectral range of 874-1734 nm was used. Partial least squares regression (PLSR) was applied to build calibration models for SO 2 residual content detection. Successive projections algorithm (SPA), weighted regression coefficients (Bw), random frog (RF), and competitive adaptive reweighted sampling (CARS) were used to select optimal wavelengths. PLSR models using the full spectrum and the selected optimal wavelengths obtained good performance. The Bw-PLSR model was applied on a hyperspectral image to form a prediction map, and the results were satisfactory. The overall results in this study indicated that HSI could be used as a promising technique for on-line visualization and monitoring of SO 2 residual content in Fritillaria thunbergii Bulbus. Detection and visualization of Chinese medicine quality by HSI provided a new rapid and visual method for Chinese medicine monitoring, showing great potential for real-world application.

“…Lee et al [210] applied diffusive reflectance of shortwavelength near-infrared in the range of 700-1000 for predicting the amount of crude lipid of intact, whole rainbow trout. The best correlation between measured and reference values was obtained from measurements at a midposition between dorsal and adipose fins above the lateral line.…”

This paper is a review of optical methods for online nondestructive food quality monitoring. The key spectral areas are the visual and near-infrared wavelengths. We have collected the information of over 260 papers published mainly during the last 20 years. Many of them use an analysis method called chemometrics which is shortly described in the paper. The main goal of this paper is to provide a general view of work done according to different FAO food classes. Hopefully using optical VIS/NIR spectroscopy gives an idea of how to better meet market and consumer needs for high-quality food stuff.

Short-wavelength near infrared (SW-NIR) spectroscopy can provide a rapid and nondestructive determination of salt content in food products, and potentially monitor salt concentration of brines during processing. This is of significant importance for ensuring the safety and quality of cured and smoked foods. One of the constraints is having reliable models to predict salt concentration as temperature varies. The effect of temperature (4.0-42.9°C) on SW-NIR spectra (594-1,105 nm) of aqueous salt solution (0-10.03% w/v) was tested in this study. A partial least squares (PLS) model based upon spectra from the entire tested temperature range, had similar predictability for salt content as PLS models developed using spectra over shorter temperature ranges (root mean square error of prediction was 0.35% versus 0.37-0.38%). The result indicated that temperature compensation with mathematical approaches for NIR spectral measurements is feasible. This could limit the cost and time necessary to collect samples over a wide range of temperature for developing and validating calibration models for salt measurement in food processing and similar applications.
