Exploring the Sensory Odor Profile of Sourdough Starter from Ancient Whole-Wheat Flours in the Development of Cookies with Enhanced Quality

This study investigates the benefits of sourdough fermentation using ancient whole-wheat flours in the development of cookies, leveraging innovative rapid sensory evaluation methods to highlight their unique sensory attributes and potential health advantages. The spontaneous fermentation of wholegrain wheat, spelt, Khorasan, and emmer flour-water mixtures was monitored, focusing on odor development. Temporal Dominance of Sensations (TDS) was employed to track how sourdough odor unfolds over time while Check-All-That-Apply (CATA) and Hedonic tests were applied to capture the sensory characteristics of sourdough starter samples and consumer overall liking in order to identify sourdough with the most appealing odor for cookie preparation. Based on the result, spelt and Khorasan lyophilized sourdough were used for cookie preparation. Further, Rate-All-That-Apply (RATA) was applied to investigate the sensory profiles of the developed cookies and panelists' hedonic perceptions and attitudes toward them. The resulting sourdough cookies exhibited higher fiber and comparable protein and fat content, lower energy value with sensory properties comparable to those of commercial samples. This research not only presents a comprehensive selection of sensory methodologies ideal for product development but also offers valuable insights into the sensory profile of sourdough-containing cookies, paving the way for enhanced formulation and strategic commercialization.
