Wafer Biscuits Manufacturing – Technological Insights and Developments

Wafer biscuits, mostly a combination of crisp, light wafers with fillings and optional chocolate enrobing are a small, 5 to 10 percent segment within the about 80 Bio$ biscuit market worldwide. After an overview on the different products from both, low/no sugar wafers and sugar wafers the emphasis is on technological issues in wafer manufacturing.

Fluid batters and the steam leavening generate the typical light texture. Technical developments, the basis of better products and the perspectives are discussed. Wafers after baking are sensitive to moisture and require good packaging. The playing ground for product development in wafers are: texture, forms, and fillings. The presentation finishes with trends and outlooks in today’s wafer biscuit market.
