Methods for the detection of taints in food
From June 2011 newsletter
There has been an increasing incidence of taints in food
and drink in recent years, which has created problems for
parts of the industry. The presence of a taint in a product
is a significant cost to industry, creating large amounts of
waste from spoiled products, and can present a potential
health hazard to consumers.
There are three major sources of food taints - environment (e.g. direct contamination via exposure to a range of airborne chemicals, chlorinated cleaning fluids, phenols and solvents), packaging (e.g. migration or scalping), and microbial (microbial action on food components to produce taints, e.g. trichloroanisole, skatole, ethyl acetate).
A new member subscription–funded project is identifying causes for taints and developing strategies for their minimisation in food and drink, and is focusing initially on halophenols and haloanisoles.The aim is to have clearly defined methods for the detection of taints in a range of sample matrices by the end of the year, and to follow this up with guidance on taint formation, toxicity, how to avoid taint issues, and implications when contamination has occurred.
