A Holistic Approach to Enhancing Bakery Products’ Quality and Health Benefits with Saffron Petals—A Review

Year: 2026

Type: article

Abstract: L.) production, approximately 53 kg of petals are obtained as a by-product for every 1 kg of saffron spice. The use of saffron petals and petal extracts in bakery products improves products' shelf life due to the petals' high content of nutraceuticals and minerals acting as natural preservatives. Petal-enriched bakery products contain high levels of fiber, minerals and antioxidants. Addition of saffron petals into bread dough reduces gluten network strength, increases crumb hardness, enhances acidity, improves water retention, alters color profiles and increases the duration of the shelf life. The formulation for incorporating saffron petals or petal extracts into food products must address three primary criteria: the maximum concentration of bioactive compounds per 100 g of the finished matrix, the thermal stability of these compounds during the baking process, and their bioavailability (in the food matrix) within the human gastrointestinal tract. Nutraceuticals with pharmacological potential are also influenced by the compositional profile: the proximate composition, minerals, phenolic content, flavonols, and antioxidant capacity of saffron petals and bakery products containing saffron petals. Saffron petals exhibit diverse therapeutic potentials, acting as antidepressants, anxiolytics, anticonvulsants, and neuroprotective agents. They also offer metabolic, cardiovascular, hepatoprotective, and renoprotective benefits, along with anti-inflammatory, antimicrobial, and antitumor activities. This article proposes a roadmap for developing bakery products enriched with saffron petals or petal extracts, targeting both pharmacological applications and consumer goods focused on disease prevention and general wellness. This study investigates the biochemical composition of saffron petals and their integration into bakery products. It evaluates the influence of petal-derived additives on rheological properties, shelf stability, and organoleptic characteristics, alongside an assessment of their bioactivity and toxicological profiles. Furthermore, the analytical methodologies employed for ingredient and biological sample characterization are discussed, emphasizing their role in verifying the authenticity, safety, and nutritional functionality of both raw materials and finished formulations.
