Clean-Label Reformulation Strategies in Industrial Bakery Products: A Review

Consumer distrust of synthetic additives has reshaped ingredient strategy across the global bakery sector, pushing formulators toward “clean-label” products defined by short, recognizable ingredient lists and minimal processing. This review synthesizes the peer-reviewed literature on clean-label reformulation in industrial baked goods, covering sodium reduction, sugar reduction, saturated-fat replacement, additive-free shelf-life extension, natural colorant and whole-grain/fiber fortification, and the replacement of synthetic dough conditioners with enzymes, sourdough fermentation, and natural hydrocolloids. Across these domains, a consistent pattern emerges: ingredients removed for clean-label reasons rarely perform a single function, so their replacement typically requires a combination of technologies rather than a one-for-one swap. Sourdough fermentation surfaces repeatedly as a multifunctional tool addressing sodium perception, sugar replacement, and antifungal shelf-life extension simultaneously, while enzymes and oleogel-based fat-structuring systems offer more targeted, single-function solutions. The review considers where these technologies sit on the path from laboratory demonstration to commercial deployment, and closes with a discussion of unresolved scientific and definitional gaps. A subset of the numeric claims made throughout this review were checked directly against open-access full texts rather than relying on abstracts alone; a verification appendix at the end states, claim by claim, which figures carry that higher confidence level and which remain single-source or abstract-derived.
