Shelf-life study of a food, feed or dietary supplement product
Shelf life refers to the time between the production date and the "best before" or "use by" date of a product. In the EU, the date of minimum durability is mandatory food information for almost all packaged foods, supplements, and feed products.
During the product's shelf life, when stored according to instructions, the product should:
Not pose a microbiological hazard to the consumer. Microbiological risks are usually more prevalent in perishable products, such as raw meat and dairy, but must also be accounted for with more stable products with a longer shelf life.
Not pose a chemical hazard to the consumer. Certain toxins may accumulate in the product due to microbiological activity. It is also possible that the packaging material is not fully compatible with the contents, causing contaminants to leach into the food or feed.
Retain all relevant characteristics, such as nutritional value, consistency, and flavor.
There are various approaches to assessing the stability of food products over their intended shelf life:
Sensory analysis can be used to assess the retention of sensory properties, such as flavor and odor.
Nutritional analyses, measurement of water activity, and pH give information about changes in composition. They can also be used to assess microbiological stability and risks.
Nutrient level monitoring is necessary for products containing vitamins and other nutrients to ensure that nutrient levels are maintained throughout the shelf life.
Fat oxidation parameters, such as peroxide, p-Anisidine, and TOTOX value, can be used to assess the oxidative stability of fat-containing foods. Fat oxidation parameters can, in some cases, also explain a downward trend in sensory quality.
Shelf life studies can be conducted in real-time using the storage conditions described in the packaging. Alternatively, accelerated studies in elevated temperature and/or relative humidity can be performed to approximate the shelf life within a shorter time frame. In addition to the best-before or use-by date, the period after opening can also be determined.
Every shelf life study is unique, and the testing conditions, duration, and analyzed parameters are chosen based on product characteristics and related risks.
