Shelf Life Dating Of Foods

A study published Wednesday by Harvard Law School and the Natural Resources Defense Council found that dates printed on packaged foods, which help retailers cycle through stocked products and allow manufacturers to indicate when a product is at its peak freshness, are inconsistent. They confuse consumers, leading many to throw out food before it actually goes bad. Manufacturers often decide on their own how to calculate shelf life and what the dates mean. As a result, huge amounts of food, not to mention considerable natural resources and labor, go to waste in landfill and taxes, and harm the environment. A lack of binding federal standards on labeling means the dates are governed by a patchwork of state and local laws. David Fikes, a spokesman for the Food Marketing Institute, which represents food retailers and wholesalers, said the group agreed there had to be a clearer way for the consumer to read dates. However, it disagreed the code should be hidden from consumers, because that would make it difficult for store employees to stock shelves. Lack of understanding about the labels is not necessarily a health hazard.

Harvard study finds food expiration labels are misleading

Since the s, food consumers across the globe have demanded shelf life dates on food packages that help them decide both purchase and consumption. The establishment of such dates by manufacturers and their interpretation by consumers, however, has never been coherent. Up to the present, the implementation of quality-based shelf life dates has remained the main factor for establishing the end date or shelf life for all food products.

However, label dates alone do not ensure the safety of food.

Shelf life is the length of time that a commodity may be stored without becoming unfit for use, The concept of expiration date is related but legally distinct in some However, shelf life alone is not an accurate indicator of how long the food can Labuza, T. P., Szybist, L., Open dating of Foods, Food and Nutrition Press.

The most direct way to estimate the shelf life of a product is to conduct simulation tests which are time consuming and expensive. Conversely, accelerated shelf life tests can be successfully used for stable products having long expected shelf life. The aim of the study was directed to verify the possibility to apply an accelerated shelf life test to perishable food products having a short-expected shelf life, such as a new ready-to-eat processed food preparation, composed mainly by cereals, tuna and chicken, packed in thermo-sealed trays and pasteurised.

Different samples of the product were stored in thermal abuse conditions, collected periodically and subjected to determinations of TVB-N, pH and sensorial characteristics. The product shelf life was assessed at 26 days vs the 30 days expected by the manufacturer, showing the possibility to apply successfully ASLT for products having short shelf life, saving both time and money. All sectors of the food and drink industry are under increasing pressure to rapidly develop and launch new and innovative products to maintain market share.

Part of the product development cycle is to set a suitable shelf life. For ambient stable products with long shelf life, commercial pressure means it is rarely feasible for full shelf life evaluations to have been completed prior to product launch Campden Bri, For the chilled foods sector, although the shelf lives are much shorter, they might extend to weeks and it has been demanded to determine the shelf-life in less than half of this time or shorter.

Shelf life is length of time that food can be stored safely. Food cannot be kept forever. After a certain time it will go bad. After this time it is no longer safe to eat it. Shelf life is also used for drugs , drinks and other things that can go bad. In some countries, a best before , use by or freshness date must be put on packaged foods. During this time, if the food is kept under proper conditions the quality of the food does not change.

Frozen food that does not remain frozen will go bad earlier, for example. Most of these labels do not guarantee the safety of food. They should only be used as a guide.
