Frozen bakery products occupy a critical position in modern food systems because they enable centralized production, extended distribution, and on-demand baking. However, frozen dough and par-baked items remain vulnerable to ice recrystallization, gluten network disruption, yeast inactivation, starch retrogradation, and oxidative rancidity. These interacting failure modes reduce shelf life quality, increase waste, and constrain supply chain resilience. This paper develops a system-level analysis of natural antioxidant–cryoprotective systems as an alternative to conventional synthetic dough additives. It examines how plant-derived polysaccharides, polyphenol-rich extracts, and structured hydrocolloid matrices can simultaneously regulate ice morphology, stabilize dough interfaces, and suppress oxidative reactions. The discussion addresses structural trade-offs among cryoprotection, dough rheology, sensory neutrality, and cost. It also considers integration with industrial freezing infrastructure, packaging, digital cold chain monitoring, and decision-support architectures. Governance and regulatory dimensions are analyzed through the lens of clean label requirements, food additive approval regimes, and quality assurance frameworks. Sustainability implications include reduced food loss, lower life-cycle impacts, and better alignment with circular food system objectives. The analysis further considers fairness and accessibility, since natural preservation systems must be economically viable for small and medium bakeries in diverse regulatory environments. The paper argues that effective deployment depends not on a single ingredient but on coordinated design across formulation, freezing operations, distribution governance, and monitoring infrastructure. It concludes by identifying forward-looking research directions in structural biopolymer design, process integration, and decision systems that can jointly improve frozen bakery shelf life while supporting resilient and sustainable food supply networks.
