Accelerated shelf life testing protocol.

Real time assessment is usually time and resource consuming. Accelerated shelf life testing is often employed to obtain advance indications of the performance of newly formulated products and products destined for tropical markets. Shelf life studies can come in many different forms including accelerated studies. 75 for some or all of the following tests.

Aslt is a form shelf life assessment. Epa has determined that studies using this protocol will in certain circumstances provide us with all the information we needs to make a determination on the storage. It can notbe used to test for microbial growth. 40 deg c relative humidity.

Exposure to north light in the northern hemisphere or a light box with appropriate wavelength light of the required intensity may be used for color sensitive products but the majority of accelerated testing is carried out at increased temperature typically 35 40 c. The product is then evaluated at specific intervals to monitor any potential degradation in quality or food safety. Most package shelf life validation protocols. In these studies accelerated conditions i e.

This process is performed using the q10 value. Scope of astm f 1980 provides information for developing. A non guideline accelerated storage stability and corrosion characteristics study can be used at the registrant s discretion to fulfill data requirements for storage stability. Where appropriate comply with any label.

The institute of food science and technology defines shelf life as the period of time during which the food product will remain safe. What is an accelerated shelf life study. This approach is particularly advantageous for those products that are characterized by a long shelf life such as ambient stable and frozen foods. 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 the commodity.

Be certain to retain its desired sensory chemical physical microbiological and functional characteristics. There are many definitions of shelf life provided by governments and organizations. Accelerated studies will assess changes in moisture content water activity oxidation of fat and sensory characteristics. Elevated temperature are applied to eligible products to predict product shelf life at typical storage conditions.

The number of days that the product remains stable at the recommended storage conditions is referred to as the shelf life. What is shelf life. If properly applied this procedure known as accelerated shelf life testing aslt allows estimation of the shelf life data at storage conditions usually experienced by the product on the market by using data acquired at accelerated storage conditions labuza and schmidl 1985. Typically 12 week accelerated shelf life temperature.
