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…

The presence of foreign bodies (FBs) in processed foods is one of the major concerns of the food industry, and their detection and identification are important in quality assurance and safety. An FB is any undesirable piece of solid matter present in a food product. When foods are manufactured or…

Microbial analysis in foods is an integrated part of management of microbial safety in the food chain. Both competent authorities and individual food business operators use microbial analysis for monitoring of the actual situation and trend analysis in order to detect emerging risks. For compliance testing to defined microbiological criteria…

Fats are present in most food products and they have a significant importance for fat-containing products such as chocolate and butter. The physical properties of fats depend on the polymorphic behaviour and inter-solubility of their major triacylglycerol components and the phase behaviour of these mixtures is of paramount importance for…

Consumer expectations of product quality for food emulsions drive the industry to continuously invest in new production methods. Membrane emulsification (ME) has been known for many years and its potential is emphasised in numerous scientific publications. ME is said to ensure highly controlled production of particulates and be a more…

Pasta is apparently a very simple food, with one ingredient: semolina of durum wheat and one reactant: water. In its native state, the ingredient has two main constituents, which are proteins and starch. The reactant, together with mechanical and thermal energy, is necessary to modify their structure to obtain the…
For food processing applications, ohmic heating may be defined as a process where an electric current is passed through the food with the main purpose of heating it. Under these circumstances, heat is internally generated due to the food's electrical resistance1 and this simple fact is responsible for the particular…

The launch in September 2005 of the ISO 22000 series, developed by ISO technical committee ISO/TC 34, Food products, signalled the arrival of a truly global option for ensuring safe food supply chains. This article gives a technical overview of the different standards in the series and how they can…

Some of you may have read details of the standard ISO 21469 which covers ‘Safety of Machinery - Lubricants with Incidental Product Contact - Hygiene requirements,' and may wonder why the food industry or the lubricants industry need yet another standard to which they should adhere.
