Historically, maintaining the hygiene of a food process required a complete or partial disassembly and manual cleaning of every component (Cleaning out of Place: COP). The 1950’s saw the development of a method to clean the equipment without dismantling (Cleaning in Place: CIP) with the benefit of better repeatability, reduced…

Wafers offer a unique sensorial experience to consumers. Driven by consumer trends towards products which are lighter but still indulgent, the wafer category is expected to grow further. Wafers are seldom eaten alone and are often combined with components with a contrasting texture, such as chocolate or ice cream. Wafers…

This article presents a perspective on food additives, how consumers understand them and their labelling. It also highlights the evolution of consumer information obligations and expectations in the light of new EU Regulations. There are likely to be many reasons why con - sumers consult food labels and the reasons…

Fresh leafy vegetables (e.g. lettuce, spinach, escarole, cabbage and other baby leaves used in salad mixes) are an important part of a healthy diet. Global consumption levels are expected to increase in the future. However, due to recent disease outbreaks and rapid alerts attributed to fresh produce, concerns have emerged…

The discovery in 2002 that cooking of various foods at high temperature (exceeding 100°C) results in the formation of high levels of acrylamide1 has caused considerable concern because this compound has been classified as ‘probably carcinogenic to humans’ by the International Agency for Research on Cancer2. In fact, acrylamide levels…

Although traceability is often associated with food safety, increasingly the tools provided by a traceability system are being used for much more than food safety. The research carried out into traceability, initially spurred on by concerns over food safety, has expanded to include a wide range of different aspects of…

A real-time automated process control tool for coffee roasting was developed to consistently and accurately achieve a targeted roast degree. It is based on timeresolved on-line monitoring of volatile organic compounds (VOC) in the off-gas of a drum roaster, using Proton-Transfer-Reaction Time-of-Flight Mass-Spectrometry (PTR-TOF-MS). These experiments provide a detailed, real-time…
Milk is a highly perishable food so to enable it to be stored and distributed for consumption without spoilage, and without being a health risk through growth of pathogenic bacteria, it is heat treated. The most common type of heat treatment in many parts of the world is pasteurisation, which…

Since the pioneer discovery of nuclear magnetic resonance (NMR) spectroscopy by Isidor Rabi in 1938, it has become a central analytical technology in multiple scientific domains of chemistry, physics and biology. Uniquely suited to measure the spin properties of magnetically active nuclei, NMR has emerged as a very popular technique…

The production of emulsions with very low mechanical stress and a lower energy input than conventional mechanical methods have been developed in recent years and will be presented in this overview, the so-called membrane and microchannel emulsification. They are efficient processes due to their operational flexibility, reproducibility, straightforward upscaling and…

‘Something is fishy’ is a widely used expression over a doubtful, suspicious situation, a good example of how mankind has taken advantage of microbial spoilage to assess the wholesomeness of a food product. The reduction of trimethylamine oxide to trimethylamine by bacteria associated primarily with the marine environment (e.g. Alteromonas…

Many bacteria are able to attach to and colonise environmental surfaces by producing a biofilm, which allows the organisms to persist in the environment and resist desiccation, UV light and treatment with antimicrobials and sanitising agents. Biofilms are formed when microbes attach to a solid support and to each other…
