Shimadzu Selection

These articles were selected by Shimadzu. Relating to food analysis, they are from
application notes and technical reports. They feature a variety of instruments we
produce and include cutting-edge technologies. Please obtain the articles of your
interest through the links on the titles.

Selection 1 Food Analysis
FTIR-ATR Characterization of Commercial Honey Samples and Their Adulteration with Sugar Syrups
Using Chemometric Analysis
Honey is a valuable food commodity that gains a lot of attention due to its potential health benefits and usage to sweeten foods
and beverages. To save on manufacturing costs, honey is susceptible to deliberate adulteration with sugar syrups such as corn
syrup. FTIR with attenuated total reflectance (ATR) was used to collect absorption spectra of various commercial honey samples.

Selection 2 Food Analysis
In Wine There is Truth - The Characterisation and Quantitative Analysis of Wine Using
Spectroscopic Methods
Due to globalisation, food is no longer a local product, but may be transported over thousands of kilometres from its source
to where it is consumed. Unfortunately, the additives for preservation as well as the packaging material are potential sources
of contamination. From the very beginning, Shimadzu has been involved in the development of analytical methods related to
European regulations and food guidelines. One recent example is the European wine regulation. This paper shows the
Shimadzu spectroscopic methods for residue analysis and quality control of wine.

Selection 3 Food Analysis
Analysis of Sugars and Sugar Alcohols in Energy Drink by Prominence-i with Differential
Refractive Index Detector
Sugars and sugar alcohols display almost no ultraviolet absorption, and are therefore typically detected using a differential
refractive index detector or evaporative light scattering detector. This note presents an example of simultaneous analysis of sugars
and sugar alcohols in an energy drink using the Prominence-i and RID-20A.

Selection 4 Food Analysis
Simultaneous Analysis of Water- and Fat-Soluble Vitamins in Beverages Using an ODS-Modified
Metal-Doped Column
In this study, a Shim-pack MAqC-ODS I was used to analyze water- and fat-soluble vitamins in a single method. This column
contains ODS-modified and metal-doped stationary phase, so it was able to retain the weakly-retained components without
ion-pairing reagents.

Selection 5 Food Analysis
Quantitative Analysis of Anabolic Steroids in Control Samples from Food-producing Animals
using a Column-switching LC-HESI-MS/MS Assay
The use of natural and synthetic hormones to increase the weight of meat-producing animals is prohibited in the European
Union. This paper shows the development of an online-SPE method to considerably shorten the pre-treatment time. In
addition to optimisation of the extraction method, chromatographic separation was optimised to decrease ion-suppression
and isobaric interference.

Selection 6 Food Analysis
Quantitative Analysis of Veterinary Drugs Using the Shimadzu LCMS-8050 Triple Quadrupole
Mass Spectrometer
Foods in which chemical residues, like pesticides, feed additives, and veterinary drugs, found in excess of maximum residue levels
have been banned from sale in many countries around the world. This Application News introduces an example of the
high-sensitivity analysis of 89 veterinary drugs in a crude extract of livestock and fishery products.
