Determining spatial sodium distribution in fresh and aged bread using laser-induced breakdown spectroscopy

Atomic_25_3-F1-sMost of us are increasingly aware of the dangers of the modern diet and realise that salt intake should be kept low. It turns out that bread is a major contributor to our salt intake. However, without it, the bread is not particularly palatable. One trick is to distribute the salt unevenly throughout the bread, but the salt then needs to be encapsulated to prevent it dissolving. This article describes the use of laser-induced breakdown spectroscopy to monitor this distribution and help develop methods to reduce the salt content of bread whilst maintaining the taste.

Surface-enhanced Raman scattering (SERS) spectroscopy identifies fraudulent uses of fuels

SERS-25-2-sFuels and the taxes raised from their sale are a big business around the world. To control smuggling, counterfeiting, theft and product diversion, markers can be placed in the fuel. The use of a SERS active compounds as markers is described as well as the development of a portable instrument for detection of the markers in the field.

Nuclear magnetic resonance-based approach to fruit characterisation: the case studies of kiwifruits and peaches

nmr-sMany analytical methods have been used to control the quality, authenticity and origin of fresh fruit. NMR methodologies yield a comprehensive metabolic profile, provide direct structural information regarding individual metabolites in the mixture and also give information regarding the water state in the tissue. This is useful in discriminating various fruits varieties, in investigating nutritional properties, in monitoring the development of the fruit and in assessing the optimum harvesting time.

Qualitative and quantitative assessment of acetylated wood using infrared spectroscopic methods and multivariate data analysis

Chemical modification of wood by methods such as acetylation is required to improve characteristics such as photosensitivity and combustibility, and to provide harmonisation of wood properties in order to avoid swelling and shrinking and to improve bio­degradability. The authors describe the use of mid and near infrared spectroscopies to monitor chemical changes due to acetylation is described.

Pyrolysis, spectroscopy and extraterrestrial organic matter

Space-25-1-F4-sThis article shows that pyrolysis techniques, in combination with spectroscopy, are helping our understanding of how the organic matter in our solar system came to be. Fascinatingly, they also show how secondary processing of meteorite materials seems to enhance the abilities of atmospheres to host life on planetary surfaces as well as providing the raw materials from which life could originate.
