How to define the sound of crusty bread?

10 Nov How to define the sound of crusty bread?

Focus on one of its senses that we sometimes forget: the SOUND of crusty bread.
The sound of the Baguetresse: Crunchy – Crispy

An essential tool for professionals in the breadmaking industry, sensory analysis consists of highlighting and describing the organoleptic properties (appearance, smell, sound, texture, taste) of bread by a panel of experts and consumers. 

The “sound” criterion in sensory analysis

Sensory analysis, a tool for the breadmaking industry

Recognized for their sensory expertise, Lempa and Lesaffre have jointly developed a lexicon of precise sensory descriptors adapted to crusty breads. This tool, used by supermarkets, manufacturers or artisans in their marketing, R&D and Quality approaches, makes it possible to relate two approaches: that of consumers (not informed), more subjective and that of experts (having followed specific training ), more objective.

The importance of the “sound” criterion

Rather crisp or crisp, the bran of the bread is a very important characteristic that tells us in particular about its freshness. Sharing experience, Carine CNUDDE, Bread Technical Development Manager, in the Bakery – Viennese pastry – Pastry industry .

“The texture of a bread is a concept that is, in my opinion, fundamental. I characterize it by the balance between the texture of the crumb and the texture of the crust. Crunchy and crispy are terms often used to characterize the crust, but they are terms that are not easy to define and understand. The consumer describes it more intuitively when talking about an easy or difficult to eat bread. Consumer appreciation is conditioned by his use of bread (eg sandwich bread or accompanying bread) and there are also generational differences (thick crust less popular with young people). Consumers are either looking for breads with a thin, crisp crust, or breads with a more rustic appearance and a thick crust. In both cases,

To meet this market demand, Marketing and R&D work in close collaboration. We closely follow consumer trends and develop breads by choosing specific ingredients and adjusting manufacturing processes in order to obtain good crispness and optimal taste ”
