M. C. GACULA JR., Armour Food Research Laboratory. Shelf life is a parameter of the lifetime distribution of a food product, usually the time until a specified proportion (1-50%) of the product has spoiled according to taste (Freitas et al. Conduct an informal study yourself and take notes. The most direct way to estimate the shelf life of a product is to conduct simulation or real-time stability test that corresponds to the time of decay of a food under optimum storage conditions. A shelf life study is an objective means to determine how long a food product can reasonably be stored and used, without any appreciable change in quality. Careful consideration of experimental design and test parameters is essential for accurate shelf life evaluation. We will touch on real-time aging later in this article. Shelf life = Study time period x Factor . 11. Samples that have

If long-term condition or accelerated condition data shows change then statistical analysis is used to estimate the shelf-life of the drug product. With a real-time shelf life study, the food is stored under normal conditions for a period of time greater than the estimated shelf life. The state of the food is verified at regular intervals to determine the point at which it deteriorates and no longer has the quality, nutritional value, microbial, chemical and physical integrity it should have For example, a study on shelf-life extension of salmon slices 14, the samples were purchased from different markets, assigned to 5 treatments with one being a control, and stored at 1C.At 0, 3, 6, 9, 12, and 15 days of storage, samples were cooked and examined by 15semi-trained panelists for overall acceptability on appearance, odor intensity, salmon flavor, The FDA will accept accelerated shelf-life testing as long as real-time testing is completed in parallel. The shelf life was determined with respect to physicochemical and microbiological characteristic changes monitored during storage. help estimate physical, chemical, and microbiological stability of the food.
