Experimental accelerated shelf life determination of a ready-to-eat processed food
New technologies to predict spoilage time could slash the massive waste between farm and fork. In August , a can of Great Value peas joined the nonperishables in my pantry, one of several panic purchases as Hurricane Irene barreled toward my home on the northeast US coast. But the emergency passed, and the can, with its unassuming blue-on-white outline font, remains on my shelf seven years later.

We delivered a copy of the posters to at least 50 of these scientists. In addition we collected their business cards and sent them an email with a link to Dropbox where we have in one folder all the presentations given and papers published since we started this work on protein aggregation in We also gave 2 oral presentation to Davisco International Inc, who are one of the major producers of whey isolates in the world, and who gave us supplemental funding in the area of the work on glycation.
In addition I attended both the Chicago and Minnesota IFT sections Suppliers Day meeting where there were at least and table top exhibitors, respectively. I delivered info on our functionality work to all the protein exhibitors I could find about 45 in total. In addition we have a review paper published in Critical Reviews in Food Science and Nutrition which has an impact factor of 4.
The paper is a review focusing on storage stability of food protyein hydrolysates, and was commissioned by the Midwest Dairy Center. It should be noted that we are collaborating on this work with Dr. Peng Zhou of Jingnan Univ. He has given at least 5 lectures in China on our combined work.

Shelf-life dating of foods by Theodore
The premise of the report is that a confused dating system for foods in the US leads consumers to prematurely discard edible food. I talked to Dr Labuza in pursuit of some more information about why food rots, and more importantly, how to get the most bang for my buck by how I store and take care of my food. What exactly is food science? What is food engineering? How did you get into that line of inquiry? I went to MIT as an undergraduate.

Labirint Ozon. Open Dating of Foods. Theodore P. Labuza , Lynn M. Open dating plays a vital role in the distribution of the food products from the farm or place of manufacturing to the consumer’s home. One principle is that the shelf life is a function of the distribution conditions and can be looked at as the percentage of consumers a manufacturer is willing to displease. Thus, one purpose of an open date is to give consumers enough time to purchase a food product and store it at home for a reasonable period of time before the product reaches the end of shelf-life in terms of some degree of quality change that is still acceptable.
If products are not stored or rotated properly in distribution, then older products or those of lesser quality and perhaps compromised safety because of abuse during distribution chain and causing loss of confidence in the food category. Presently, the lack of uniformity among manufacturers and across state borders has made the practice of open dating confusing and misleading for consumers, retailers and the government.
This book addresses these issues, and provides scientific and legal background to both evaluate and influence federally-regulated open-dating legislation in this country. Open Dating of Foods Theodore P. Labuza, Ph.
Experimental accelerated shelf life determination of a ready-to-eat processed food.
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.

Predicting shelf life is a problem and a challenge, says Juan L. He defi nes shelf life as the time during which a food product stays at its optimum quality and is still safe to eat. Other variables can complicate and compromise shelf life, Silva adds. In part, this can be due to abuse by the consumer. According to Silva, determining shelf life in the laboratory includes the use of environmental chambers to control light, temperature, and relative humidity.
However, shelf life analysis is only complete when tied to sensory evaluation, he points out. So many variables make it diffi cult to forecast shelf life, even with all the models available.

Many food products have some variation of open shelf-life dating Labuza () has reported that quality loss follows the following equation.
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.
The U. Food and Drug Administration requires expiration dating on prescription drugs, some over-the-counter drugs, and infant formula. Putting an open date on other food products is voluntary. Currently 30 U. Some food products in Denmark are required to list a pack date, sell-by date, and use-by date, thus satisfying both retailer and consumer demands. In such cases, the date of minimum durability is replaced by a use-by date.

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.

It doesn’t all end up in the trash. Once food hits its sell-by date, many markets donate products to food banks or sell them to salvage stores. As darkness falls, your local supermarket becomes a hive of activity. From canned vegetables and salad dressings to fresh fruits and deli meats, countless items are removed from shelves by night staff. Approaching their expiration dates or because they are no longer at their peak quality, most stores consider them unfit for sale.
With 15, different products in an average supermarket and 25, in a superstore according to the Food Marketing Institute FMI , retailers in the U. So what comes of all of this food? Fresh vegetables and meats are often cooked up for in-store deli and salad counters before they spoil, says supermarket consultant David J.
