Current Practices And Regulations Regarding Open Dating Of Food Products

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.

wasted food, NrDC and Harvard recommend that food date label regulations are improved to the store that the product did still have shelf life left.1 24 Telephone Interview with Dr. Theodore P. Labuza, Professor of Food.

Harvard study finds food expiration labels are misleading

The system can’t perform the operation now. Try again later. Citations per year. Duplicate citations. The following articles are merged in Scholar. Their combined citations are counted only for the first article.

You can’t tie shelf life to a date,” Labuza said. “If the food looks rotten and smells bad, you should throw it away, but just because it’s past the date.

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. In accelerated shelf life tests, the chemical, biochemical and microbiological changes may be induced in shorter time, that it would not otherwise occur.

All foods are composed by biological material undergoing to degradation or spoilage beyond a certain period of time; this deterioration belongs to that processes that cannot be fully blocked. The shelf life is the time in which the product remains, after manufacture and packing, safe and suitable to use, in defined storage conditions.

Shelf life is the length of time that a commodity may be stored without becoming unfit for use, consumption, or sale. It applies to cosmetics , foods and beverages , medical devices , medicines , explosives , pharmaceutical drugs , chemicals , tyres , batteries , and many other perishable items. In some regions, an advisory best before , mandatory use by or freshness date is required on packaged perishable foods.

The concept of expiration date is related but legally distinct in some jurisdictions. Shelf life is the recommended maximum time for which products or fresh harvested produce can be stored, during which the defined quality of a specified proportion of the goods remains acceptable under expected or specified conditions of distribution, storage and display. If the cans look okay, they are safe to use. Discard cans that are dented, rusted, or swollen. High-acid canned foods tomatoes, fruits will keep their best quality for 12 to 18 months; low-acid canned foods meats, vegetables for 2 to 5 years.

Most food is still edible after the expiration date. In most food stores, waste is minimized by using stock rotation , which involves moving products with the earliest sell by date from the warehouse to the sales area, and then to the front of the shelf, so that most shoppers will pick them up first and thus they are likely to be sold before the end of their shelf life.

Some stores can be fined for selling out of date products; most if not all would have to mark such products down as wasted , resulting in a financial loss.
