Brominated vegetable oil was used as an emulsifier system for many years, but while of very good technological performance was with-drawn due to safety fears. Many alternatives have been sought including sucrose esters, such as sucrose diacetate hexa-isobuty-rate, rosin esters, protein clouds, benzoate esters of glycerol and propylene glycol, waxes and gum exudates. None have achieved universal acceptance and unacceptable background flavour is a common problem, especially with rosins and gum exudates. A new product based on modified soy protein may, however, prove satis factory.
