Food By-Product Valorisation for Enriched Bakery Formulations
Turning food-processing side streams into enriched bakery formulations through recipe development, nutritional analysis and consumer feedback.
The development process uses an enriched dough to control ingredient incorporation and bakery performance. Prototype work examines recipe composition, dough stability, rising and maturation, baking performance and storage conditions. The evaluated formulation includes 30% HiPrOat oat by-product and 5% liquid gluten.
The formulation is under development. Nutritional values relate to the tested bread. Glycaemic response, shelf life, food safety and commercial readiness require product-specific validation.
The Crete food value chain incorporates oat- and carob-processing by-products into enriched bakery formulations. Development focuses on preparing an enriched dough that can be used consistently by bakeries. This approach was selected in place of producing a separate enriched flour, because direct formulation gives greater control over dough performance and practical use in bread making.
Prototype production examines the behaviour of the dough throughout preparation and baking. The work includes dough stability, rising ability, maturation, recipe composition, production conditions and storage parameters. Organoleptic quality is considered alongside nutritional characterisation, so that the resulting formulation can be assessed both as a food product and as a workable process for bakery operators.
The pilot brings together food-processing businesses, bakeries and research expertise to develop and test the recipes. Nutritional analysis and consumer acceptance form part of the development programme, while local distribution through the participating cluster is being explored. The research aims to create added value from food-processing side streams and develop nutritionally differentiated bakery products. Glycaemic performance and other health-related properties require the relevant measurements; they are not established solely by incorporating these ingredients.
The evaluated bread formulation uses 30% HiPrOat by-product from oat-beverage production and 5% liquid gluten. The gluten addition addresses crumb fragility and loaf structure in the fibre-rich formulation. Reported composition per 100 g includes 13.1 g protein, 8.7 g dietary fibre and 235 kcal. The comparison uses conventional white-bread reference ranges of 8–9 g protein, 2.5–3.5 g fibre and 250–270 kcal per 100 g. Qualitative evaluation describes satisfactory acceptance relative to whole-wheat bread. The reported glycaemic-index range of 50–60 is an estimate, rather than a measured glycaemic response.
The circular contribution is the use of food-processing by-products as ingredients in a new food application. The formulation work connects the properties of the available side streams with the processing and quality requirements of bakeries, allowing their potential value to be examined within a food value chain.
Environmental evaluation is linked to the actual ingredient quantities and production process, while nutritional and consumer testing address the suitability of the resulting bakery product. Prototype development establishes the recipe and operating conditions needed for subsequent assessment; it does not by itself establish a quantified environmental saving.
