Sensory and consumer sciences have evolved quite a lot over the past decade. Our ambition during this period has been to pioneer some of these changes to fully incorporate the challenge of better understanding the drivers of food pleasure, intake and satisfaction. Some of these changes are very close to…

This year’s Total Processing & Packaging Exhibition takes place against a tough backdrop for the industry. Manufacturing output fell by three per cent in the year to March 2013, according to the Office for National Statistics. On top of that, the manufacturing industry is suffering a degree of collateral damage…

Nuclear magnetic resonance (NMR) spectroscopy is an investigation technique to study matter. It is based on the properties of magnetically active nuclei, which respond to a perturbation induced in a sample by applying a radio wave pulse. The nuclei, if immersed in an intense magnetic field, respond to the pulse…

“The sensory threshold for difference detection can be considered to occur when there is a 30 per cent decrease in the concentration of a flavourant”. Flavourings are concentrated aroma chemical systems used in food and beverage formulations and as such are important in the provision of aroma and taste. Their…

The trend for clean label products has been growing since the 1980s. In 2007, the well-known University of Southampton study linked certain artificial colours (tartrazine, quinoline yellow, sunset yellow, carmoisine, ponceau 4R and allura red) and the preservative benzoate to hyperactivity and attention deficit disorders in children. Since then, interest…

Food allergies have long been known as a clinical phenomenon, with welldocumented case studies as far back as the 1920s. Their recognition as a food safety issue only arose in the 1990s partly in the wake of the remarkable increase in prevalence of general allergic diseases. In order to protect…

Coffee roasting, at first glance, appears to be a simple process: applying heat to raw coffee beans. It is important to generate and control the correct temperatures at the right time, and then stop the process when the colour of the coffee is homogenous throughout the whole bean and the…

Water is a principal constituent of dough and bread, at 40 per cent of the total mass. Ice forms when dough and bread are subjected to sub-zero temperatures. The activities of water and ice shape many aspects of the dough/bread characters. Here we sketch several of these activities, looking at…

In the last 30 years, there has been increasing attention paid to the possibility of using Near Infrared (NIR) spectroscopy to deal with different aspects of food quality assessment. Indeed, the intrinsic characteristics of this technique, which, requiring little or no sample pretreatment, allows high throughput analyses in a rapid…

Hen egg yolk low-density lipoproteins (LDL), natural nanoemulsions of 30 nanometres in diameter, are the main contributors to egg yolk interfacial and emulsifying properties. These properties are clearly due to the LDL structure through interactions between amphiphilic apoproteins and phospholipids. This structure allows transport through the aqueous phase and until…

The flavour of processed foods has changed significantly over the last 50 years. Think back to the days of the early stock cubes or the original powdered desserts which bore only a passing resemblance to the real flavour. Since then, the food industry has been involved in a continuous programme…
