säilyvyysanalyysi

Säilyvyysanalyysi, or shelf-life analysis, is a process used to determine the length of time a product can be stored under specific conditions before it is no longer considered acceptable for use or consumption. This is particularly relevant for perishable goods such as food, pharmaceuticals, and cosmetics. The analysis typically involves testing the product under various environmental conditions, including temperature, humidity, and light exposure, that mimic its expected storage and transport conditions.

During a säilyvyysanalyysi, key quality parameters are monitored over time. For food products, this might include microbial growth, changes in texture, flavor, color, and nutritional value. For pharmaceuticals, it could involve assessing the potency of active ingredients, the appearance of the dosage form, and the absence of degradation products. The goal is to identify the point at which any of these parameters fall below an acceptable threshold or exceed a predetermined limit.

The data collected from these tests is then used to establish the product's expiration date or best-before date. This date provides consumers with information about the product's expected quality and safety. Factors influencing shelf life include the inherent stability of the product's ingredients, the packaging used, and the manufacturing processes employed. Manufacturers conduct säilyvyysanalyysi to ensure product quality, comply with regulatory requirements, and minimize product waste.
