Accelerated shelf life and stability studies are a critical part of product research and development (R&D) and are being included as new and upgraded food aid products are introduced. Studies proceed until it is determined that the product is no longer acceptable based on agreed criteria. The use of new types of ingredients and modifications in micronutrient levels, types and forms (vitamins and minerals) can have an impact on both shelf life duration and organoleptic properties of FBFs through the supply chain. Accelerated aging may be regarded as sufficient evidence for the claimed shelf life on the introduction of new products. However, when quality depletion proceeds fairly slowly in the actual storage conditions, testing methodologies for shelf life determination under accelerated storage conditions can be adopted. This type of conservative relationship is appropriate for a wide range of medical polymers that have been previously characterized. (wz). Shelf life protocols and conditions should be harmonized among aid organizations working on product development for comparable data and results. Special Issue: Experimental Biology 2017 Meeting Abstracts. Problems, errors, and guidelines for using the protocol (including testing design, storage conditions, sampling, and analysis) are discussed. In this chapter, the basic principles for the application of ASLT are reviewed, with special emphasis on the application of temperature and light as accelerating factors. Accelerated shelf-life testing of foods Accelerated shelf-life studies: The trial period is shortened by deliberately increasing the rate of deterioration. Predictive models:Using information from a database to predict bacterial growth under defined conditions and then can be used to calculate the shelf life of a food. Additionally, we have the ability to determine the photostability of products using controlled lighting conditions. Accelerated shelf life studies are industry standard for new product development and should be adopted as due diligence and become standard for all new or upgraded food aid products. All products were stored at 40 degrees Centigrade (104 degrees Fahrenheit) and 75 percent relative humidity for a period of 26 weeks to mimic 26 months in real time. A general standard for accelerated testing, based on the Arrhenius Equation, is: 10 weeks at 45°C is equivalent to 1 year at ambient (~21°C) temperature. In both the actual storage and the accelerated test conditions, the change in moisture content with time is not linear. Shelf life is commonly estimated using two types of stability testing: real-time stability tests and accelerated stability tests. In addition to the prediction of product stability including colour, ASLT are useful for a number of other purposes, e.g. If you do not receive an email within 10 minutes, your email address may not be registered, View our stability and shelf life video to see how it works for yourself. ", "Accelerated shelf-life testing of foods", A general protocol for evaluating new or existing products under accelerated shelf-life testing (ASLT) procedures is presented and discussed, and the use of this protocol for predicting the shelf life of a frozen pizza product is illustrated. The products were sampled and tested seven times. The aim here was to determine the vitamin and mineral stability and integrity of United States products included in the Food Aid Quality Review (FAQR) Phase II food aid effectiveness trials. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Tests were carried out on Corn‐Soy Whey Blend (CSWB), Super Cereal Plus (SC Plus), Corn Soy Blend Plus (CSBP), Ready‐to‐Use Supplementary Food (RUSF) and Fortified Vegetable Oil. Mineral levels varied among the FBFs, mostly as expected, due partially to intrinsic differences in product ingredients. Cookie Notice | The simplified protocol for accelerated shelf-life testing is not a replacement for a more complex and advanced accelerated-aging protocol, but is instead a protocol for systems known to conform to zero, first-order Arrhenius behavior. Accelerated shelf life and stability studies are a critical part of product research and development (R&D) and are being included as new and upgraded food aid products are introduced. The simplified protocol for accelerated shelf-life testing is not a replacement for a more complex and advanced accelerated-aging protocol, but is instead a protocol for systems known to conform to zero, first-order Arrhenius behavior. Every product is unique, which is why we tailor each and every study to ensure that the shelf life determination is sound. https://doi.org/10.1016/B978-0-12-817190-5.00012-4. Shelf life assessment of food has always represented an exciting challenge for scientists, but it is also a fundamental process for food companies to maintain their brand reputation on the market. Contact Us |  A general protocol for evaluating new or existing products under accelerated shelf-life testing (ASLT) procedures is presented and discussed, and the use of this protocol for predicting the shelf life of a frozen pizza product is illustrated. Packaging material innovation is required to reduce degradation of vitamin A and other vitamins. The shelf life of a product must be backed by reputable data in order to meet the requirements of government regulatory agencies and retail partners. To learn more about our photostability capabilities and what food products can benefit check out our photostability infographic. The studies were conducted by Global Food & Nutrition Inc. and Covance Laboratories. Organoleptic characteristics: FBFs all developed a slight grainy odor over the course of their shelf lives. The National Agricultural Library is one of four national libraries of the United States, with locations in Beltsville, Maryland and Washington, D.C. Investors, Sitemap | Testing followed standard methods certified by the Association of Official Analytical Chemists (now AOAC International) and commonly used by the food industry and the United States Department of Agriculture (USDA) Official Testing laboratories. In fiscal year 2011 (Oct 2010 through Sept 2011) NAL delivered more than 100 million direct customer service transactions. " In this chapter, the basic principles for the application of ASLT are reviewed, with special emphasis on the application of temperature and light as accelerating factors. Homepage |  We use cookies to help provide and enhance our service and tailor content and ads. The samples were analyzed for vitamin content (vitamins A and C), mineral content (iron, calcium and phosphorus), peroxide levels and organoleptic properties (appearance, odor, taste, packaging appearance). While is it not mandatory in Australia some international food regulators recommend that all food be date marked to support ‘first in – first out’ food consumption. These findings highlight the role that that intrinsic values play in establishing specifications. This testing methodology is universally called accelerated shelf life testing (ASLT) and, when properly applied, allows a reduction in the time needed to estimate product shelf life. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Vitamin A levels in all fortified blended foods (FBFs) degraded substantially during testing but remained very stable in RUSF and fortified vegetable oil, both lipid‐based products. Eurofins delivers the highest levels of analytical quality and service, coupled with years of experience in shelf life determinations across a variety of product types, to deliver results you can trust. Further research is needed to optimize vitamin A delivery in the USAID food aid basket, including improving vitamin A stability in dry premixes for inclusion in FBF production and determining the most appropriate delivery mechanism. The experimental protocols commonly used for data collection that serve as the basis for estimation of shelf life are called stability tests.
