For many years, low moisture foods, such as chocolate, were regarded as microbiologically safe due to the inherent product characteristics. Water activity levels below 0.6 would prevent any microbial growth, whereas water activities below 0.85 would prevent proliferation of pathogenic / toxin formation by toxigenic microorganisms[1]. A water activity of…

Often, we get in the habit of accepting numbers from computerised displays without regard to accuracy or precision, and when we do evaluate a number, we often look at how precise it is. We forget that we can be very precisely wrong. We don't really pay close attention to numbers…

Spores from mesophilic aerobic sporeforming bacteria (Bacillus) are sometimes able to survive the thermal process of commercial sterile products and sporadically cause spoilage or food poisoning. Because of an increasing demand for more fresh products, ideally the processing temperatures should be tailored to inactivate the actual spore load rather than…

The food industry uses more and more purified natural and synthetic fragile substances today, and consequently, there is an increased need to protect these ingredients. Functional food ingredients, such as flavours, vitamins or antioxidants, are sensitive to environmental stress during manufacturing, storage and consumption of the food product. Furthermore, loss…

The ability to test products and processes has always been an essential part of new product development. Until now, food processing companies have had to conduct exhaustive tests to establish the most appropriate formulations to optimise taste and the manufacturing process. But now a new particle analysis process, pioneered by…

Refreshing in foods and drinks is a perception strongly related to mouth state after product consumption. Oral dryness and roughness are lingering perceptions negatively related to refreshing perception whereas mouth wetting perception is a positive driver of refreshing perception. Since saliva seems to be related to mouth wetting, we explored…

Hyperspectral imaging combines digital imaging with precise spectral information in each image pixel. It enables composition mapping in food and agricultural raw materials and products based on differences in the spectral signatures of the various chemical ingredients. Advances in hyperspectral cameras and image processing solutions are now making hyperspectral imaging…

The brewery by-product Brewers' Spent Grains (BSG) is composed of the insoluble cereal residue that is separated from the mash before fermentation. It is estimated that the annual production of BSG is approximately 30 million tonnes worldwide. BSG consists mainly of the insoluble covering layers of the barley malt, i.e.…

In most countries with temperate climates, cereal, notably wheat, is the most important arable crop. In a few countries such as the Netherlands, potato dominates. In the European Union, over 50 million hectares of wheat is grown against approximately two million hectares of potato, yielding some 70 million tons of…
