kasutusaja

Kasutusaja, also known as shelf life or expiration date, refers to the period during which a product can be stored and used without a significant decline in quality, safety, or efficacy. This concept is particularly relevant for perishable goods such as food, pharmaceuticals, and cosmetics. The kasutusaja is determined by various factors including the ingredients, packaging, storage conditions, and manufacturing processes. For food products, exceeding the kasutusaja can lead to spoilage, loss of nutritional value, and the potential for foodborne illnesses. Similarly, expired medications may lose their potency or become harmful.

Manufacturers typically establish the kasutusaja through rigorous testing and stability studies. This date is usually printed on the product packaging, often in formats like "Best Before," "Use By," or "Expiration Date." "Best Before" indicates the date until which the product is expected to remain at its optimal quality, while "Use By" is a safety recommendation, especially for highly perishable items. It is crucial for consumers to pay attention to these dates to ensure they are consuming or using products that are safe and effective. Proper storage, such as refrigeration or keeping items in a cool, dry place, can help products maintain their quality until their designated kasutusaja.
