Application of palladium-based oxygen scavenger to extend the mould free shelf life of bakery products

An oxygen scavenging film based on a catalytic system with palladium (CSP) was combined modified atmosphere (MA) packaging to extend the mould free shelf life (MFSL) of bakery products. Par-baked buns, toast bread and gluten-free inoculated Aspergillus niger spores were packed in normal (NA) under MA (with 2 vol.-% O ) or without CSP. Mould growth detected after 2–3 days all products NA as well CO Use extended MFSL by 8–10 days, 16–18 3–4 for par-baked bread, respectively. CSP reduced concentration headspace from < 0.01 within 105–190 min This led further increase 3–9 days. • Palladium scavenger removed 3 h. Bakery mouldy 1–2 extension at least 3–16 use CO2. Additional achieved O2 scavenger.
