Overview
- Journalists consolidated guidance from nutrition scientists and German agencies to rebut five common myths about frozen food, emphasizing that this is a synthesis of existing evidence rather than new research.
- Rapid industrial 'shock‑freezing' often preserves vitamins because produce is processed soon after harvest and small ice crystals cause less cell damage than slow home freezing.
- Shelf life for most frozen items is achieved by keeping products at about −18 °C to stop microorganism growth, so preservatives are usually unnecessary though some processed frozen meals can include additives, flavorings or enhancers.
- Food‑safety rules matter: the BfR advises heating frozen berries before eating, consumers should avoid buying damaged packages or products with heavy frost, and refreezing is only safe for certain cooled or cooked plant foods while raw meat and fish need special care.
- Practical benefits include better portioning and lower household waste compared with fresh produce, but shoppers should check ingredient lists and nutrition labels to judge healthiness and follow cold‑chain and preparation advice from BZfE and Verbraucherzentrale.
