The editors of this book have gathered together leading experts to provide the food industry with a single authoritative resource. This book first defines and classifies the field of functional foods, paying particular attention to the legislative aspects in both the EU and the USA. It then summarises the key work on functional foods and the prevention of disease. Finally, there is a series of chapters on the issues in developing functional foods in practice.
New ingredients in food processing ISBN: 1 5 The food industry is now seeing a rapidly expanding primary processing industry manufacturing tailor-made ingredients or intermediate food products for the secondary sector. This major new text offers a comprehensive guide to the range of IFPs available, their key benefits greater flexibility, functionality and more consistent quality and the ways in which their manufacture can be tailored to the requirements of the food industry.

Thomas and P. Duethi, Kerala Agricultural University Van Blaricom and Martin stated that the factors responsible for pungency are not correlated with colour retention, since the pungent component, capsaicin is retained for long periods and is still present in samples which have lost their original colour.
These results, thus establish vacuum packaging as a better technology to slow down the deterioration of capsaicin in chillies. However, the decline in vacuum packed bags was controlled while that in jute packed chilli, the deterioration was rapid resulting in very low colour values.
The degradation was much faster in jute bags stored at room temperature, since there was a free exchange of O2 and moisture content between the atmosphere and the containers as jute bags do not possess barrier properties unlike polyfilms used in vacuum packaging. In addition, the oxidative properties are enhanced at a relatively higher temperature and hence the faster degradation.
The conjugated system of double bonds in carotenoids that is responsible for their rich, intense colours is also the source of their susceptibility to oxidation Bunnell and Bauernfeind Relatively better retention of colour stored under cold storage can be justified, since lower temperature retard the degradation process.
This is in agreement with Lease and Lease who reported that the loss of colour is markedly slower at low temperature storage.
The carotenoids are sensitive to light and this sensitivity is dependent on the presence of oxygen, the light thus acting as a catalyst to induce oxidation. However, in the complete absence of air, light has little effect Bunnell and Bauernfeind This property of light acting as a catalyst can perhaps serve as an answer to the relatively higher degradation of colour among light exposed vacuum packed bags.
Moisture may protect carotenoids from oxidation through a direct effect on the free radicals produced during pigment oxidation.

Increased moisture content decreases the number of free radicals and thereby slows the oxidation rate Labuza et al. Various quality parameters viz. Among various treatments, vacuum packed chillies under cold storage were found to have the least per cent decline in various quality parameters.
