accelerated aging testing shelf life study
That means your product may not function, smell, or taste as expected when stored improperly or beyond its recommended shelf life. One week under these conditions was thought to equate to one month of normal storage for most fat-based confectionery products and those containing nuts. For example, storage at a higher temperature can result in a prediction in, say, half the time of the real shelf life, although some methods claim to deliver the information in substantially less time. In the interim, we adhere to the FDA’s previous stability testing standards for new drug substances and products. Another problem is the amount of resource it takes to validate the accelerated method. Keeping this cookie enabled helps us to improve our website. If high enough temperatures are used, proteins may become denatured.

ASLT aims to accelerate the rate of deterioration of the product without altering the mechanisms or order of changes seen in the product under normal storage conditions. Accelerated aging is optional, but real-time aging is required when establishing an expiration date. MPT is an ISTA certified packaging test lab (ID Number ST-2339) devoted to the validation, testing and design of packaging for medical device manufacturers, pharmaceutical companies, biotech companies, and the diagnostic industry. For example, when the product/package system is tested, the package also controls shelf-life so that the true shelf-life of the food itself is unknown; thus, if a new package with different permeabilities to oxygen, water, or carbon dioxide is chosen, the prior results may not be applicable. Accelerated aging testing is based on a thermodynamic temperature coefficient formulated by J.H. ASLTs are particularly useful in predicting the shelf life of ambient-stable products such as confectionery which have long shelf lives. Brea, CA 92821 The food industry has a great need to have a shelf-life test in the minimum time possible because of the fierce competition, sudden shortage of agricultural inputs, opportunity loss and low unit value of … Accelerated Aging in Detail The common and conservative means of the accelerated aging calculation is based on the Arrhenius equation which states that a 10°C increase in temperature doubles the rate of chemical reaction. However, others suggest that freezing induces changes that can be noticed by a sensory panel, in particular relating to flavour. The same basic approach may be used to study fundamental oxidation reactions, compare stability of different oils or foods, compare processing and formulation of foods, test catalysts and antioxidants, guide genetic modifications, determine “sell by” dates, or answer any number of other research questions, practical or fundamental. Study Outline The Accelerated Aging test can be run to simulate a designated time period ranging from 1 month to 5 years (or longer). Accelerated shelf life testing (ASLT) (Kilcast and Subramaniam, 2000) can be incredibly useful when setting a shelf life for an ambient product, as the developer does not need to wait for the whole of the product’s shelf life to determine the end of shelf life.

So at these parameters, 13.0 weeks would be equivalent to 2 years on the shelf and 32.5 weeks would be equivalent to 5 years on the shelf. This calculator generates a table of values for calculations based upon ASTM F1980, Accelerated Aging of Sterile Medical Device Packages. The use of ideal temperatures in shelf life studies is bad practice and likely to be misleading. Real time aging must be performed in conjunction with any accelerated aging study to correlate the results found during accelerated aging. Armed with that knowledge, you can give customers the confidence they need to purchase and safely store your product. *,
, Predicting Product Shelf Life Through Accelerated Studies. The main issue with accelerated conditions is with the production of artefacts: chemical components that would not usually occur under normal storage conditions. Then we determine the rate of degradation, which we use to predict the recommended storage lengths. Accelerated Shelf-life Test Real Time assessment is usually time and resource consuming. The product must be kept at real-time storage conditions for the required length of time to compare to the accelerated test results, thus resulting in a long lead time before the accelerated test can be used with confidence. This means that every time you visit this website you will need to enable or disable cookies again. When establishing shelf life claims, it must be recognized that the data obtained from accelerated aging testing is based on conditions intended to simulate the effects of aging on and between the materials involved. Rogers, in Food and Beverage Stability and Shelf Life, 2011.
