VANILLA POWDER - Owing to the high fat and moisture content of vanilla beans, they are difficult to powder alone and this operation is usually carried out in the presence of sugar or a similar suitable blending material. Consequently, 'vanilla powder' is normally a mixture of ground vanilla and a carrier. A minimum of 30 per cent sugar in the mixture is necessary during the powdering to obtain a satisfactory product. Care must be taken during the operation to avoid overheating which can result in the loss of volatile constituents by evaporation. An anti-caking agent, such as aluminium calcium silicate, may be incorporated in the ground mixture at a level of up to 2 per cent by weight.
