Säilyvyysanalyysit

Säilyvyysanalyysit, known in English as shelf-life studies or stability testing, are crucial for determining the period during which a product remains suitable for its intended use. This period is commonly referred to as the shelf life or expiration date. These analyses are fundamental in various industries, particularly in food, pharmaceuticals, cosmetics, and chemicals.

The primary goal of a säilyvyysanalyysi is to assess how a product's quality attributes change over time under specified storage conditions. These attributes can include sensory properties like taste, odor, and appearance, as well as physical characteristics such as viscosity and texture. Chemical changes, such as degradation of active ingredients or the formation of undesirable compounds, are also monitored. Microbiological stability is a key concern for many products, especially food and pharmaceuticals, where the growth of harmful microorganisms can pose health risks.

To conduct a säilyvyysanalyysi, samples of the product are stored under controlled conditions that simulate real-world storage, including temperature, humidity, and light. Samples are then analyzed at predetermined intervals. This can involve accelerated testing, where products are subjected to more extreme conditions to predict long-term stability more quickly, or real-time testing, which involves storing products under recommended conditions for their expected shelf life. The data collected allows manufacturers to establish a scientifically supported expiration date and ensure product safety and quality throughout its lifespan.
