Bevaringstid

Bevaringstid refers to the period during which a product is expected to remain safe and retain its intended quality when stored under specified conditions. The term is commonly used for foods, medicines, cosmetics and chemicals, and it helps producers set appropriate dates and instructions. Bevaringstid is not a single universal label; it is influenced by product type, packaging, and storage conditions, and may be aligned with or cited alongside use-by and best-before dates.

Bevaringstid is typically determined through stability testing and shelf-life studies, which assess how factors such as temperature, humidity, light, oxygen, moisture, and microbial growth affect safety and quality over time. Real-time testing, accelerated aging, and regulatory guidance may all play a role. Packaging design, preservatives, and formulation influence bevaringstid by slowing deterioration.

In practice, bevaringstid informs labeling and storage recommendations. For consumers, following storage instructions (keeping cool, dry, away from light) helps maintain the product’s bevaringstid and reduce waste. After opening in foods or medicines, bevaringstid may change and is often shortened; open-product guidance is usually provided on the label.
