Chemical food spoilage is an unwanted quality change in a foodstuff, such as staling, discoloration, the development of
off-flavours and odours (e.g. rancidity), and thinning of sauces. It can be caused, for example, by enzymic or microbial activity, oxidation or
external tainting. Understanding these changes is required before action can be taken to slow them down or prevent them. Campden BRI has
wide-ranging expertise in a variety of areas which can help you identify the cause of the problem:
- Texture – such as the thinning of sauces from starch degradation.
- Colour – including discoloration of meat, fruit or vegetables.
- Off-odour and Off-flavour:
- Breakdown of proteins in meat.
- Taint from packaging, environment or processing.
- Rancidity from lipid oxidation or hydrolysis.
Enzyme analysis can give an indication of adequacy of blanching and heat processing/cooking, and many
texture, flavour and colour issues can be caused by specific enzyme activities -amylase,
polygalacturonase, lipase, polyphenoloxidase, lipoxygenase, peroxidase, alkaline phosphatase and so on.
