Säilitamistestid

Säilitamistestid, known in English as stability studies or shelf-life studies, are a crucial part of product development and quality control across various industries. These tests are designed to assess how a product's quality attributes change over time under the influence of various environmental factors. The primary goal is to determine the product's shelf life, which is the period during which the product is expected to remain within its specified quality limits when stored under recommended conditions.

The design of a säilitamiskatse involves storing product samples under controlled conditions that simulate expected storage environments. These conditions often include different temperature and humidity levels, as well as exposure to light. Accelerated stability studies are frequently employed, using exaggerated conditions (e.g., higher temperatures) to predict long-term stability more quickly. Real-time stability studies, on the other hand, store samples under recommended conditions for the entire proposed shelf life.

During the study, various parameters are monitored and measured at predetermined intervals. These parameters depend on the nature of the product and may include physical properties (e.g., appearance, color, texture), chemical properties (e.g., active ingredient concentration, degradation products), and microbiological properties (e.g., microbial contamination). For pharmaceuticals, these tests are particularly stringent, ensuring the efficacy and safety of medications throughout their shelf life. In the food industry, they help determine expiration dates and ensure product safety and palatability. Cosmetics and other consumer goods also undergo similar evaluations to guarantee product integrity and consumer satisfaction. The data collected from säilitamistestid is essential for regulatory compliance, product labeling, and ensuring that consumers receive products that meet established quality standards.
