Shelf-Stable Food Safety
United States Department of Agriculture Food Safety and Inspection Service Food Safety Information PhotoDisc Shelf-Stable Food Safety ver since man was a hunter-gatherer, he has sought ways to preserve food safely. People living in cold climates Elearned to freeze food for future use, and after electricity was invented, freezers and refrigerators kept food safe. But except for drying, packing in sugar syrup, or salting, keeping perishable food safe without refrigeration is a truly modern invention. What does “shelf stable” Foods that can be safely stored at room temperature, or “on the shelf,” mean? are called “shelf stable.” These non-perishable products include jerky, country hams, canned and bottled foods, rice, pasta, flour, sugar, spices, oils, and foods processed in aseptic or retort packages and other products that do not require refrigeration until after opening. Not all canned goods are shelf stable. Some canned food, such as some canned ham and seafood, are not safe at room temperature. These will be labeled “Keep Refrigerated.” How are foods made In order to be shelf stable, perishable food must be treated by heat and/ shelf stable? or dried to destroy foodborne microorganisms that can cause illness or spoil food. Food can be packaged in sterile, airtight containers. All foods eventually spoil if not preserved. CANNED FOODS What is the history of Napoleon is considered “the father” of canning. He offered 12,000 French canning? francs to anyone who could find a way to prevent military food supplies from spoiling. Napoleon himself presented the prize in 1795 to chef Nicholas Appert, who invented the process of packing meat and poultry in glass bottles, corking them, and submerging them in boiling water. -
Micro-Ovenable Packages and Retortable Packages
MICRO-OVENABLE PACKAGES AND RETORTABLE PACKAGES he advent of modern urban dynamic lifestyle has created a demand for ready-to-eat food T to be met by food product manufacturers. The urban middle and upper middle class consumers have little time to do their cooking in a conventional manner and welcome ready to eat food products. The market for domestic appliances has also witnessed tremendous growth with respect to the availability of sophisticated appliances such as the microwave-oven, which has now been accepted as a modern domestic appliance for food cooking. In view of the above developments, the market needs innovative packages, which can be micro-waved and hence can be used for the packaging of ready-to-eat food products. Micro-ovenable Popcorn Packages Microwave Packaging Microwave package is a package, which can be used for cooking or heating the product in a microwave oven. Thermal conductivity of the package can affect the heat transfer between food and oven. The package alters the heating pattern of the contained food, by releasing or tapping the water vapour inside the package, thereby cooking the product under controlled pressure and temperature. Two types of microwave packages are available. One of them allows microwaves to pass through the material, they are called microwave transparent materials. Most of the conventional packaging materials are transparent to microwave. Paper, glass and all plastic materials such as polyethylene, polypropylene, polyester, nylon, polystyrene, poly vinyl chloride are all microwave transparent materials. Microwaves heat the product without interfering with these packaging materials. Their application in microwave package development depends upon their thermal stability and compatibility with the product under high temperature and pressure. -

Background Information: Teacher Background: Commercial products have frequently taken their inspiration from nature. For example, Velcro® resulted from a Swiss engineer, George Mestral, walking in the woods and wondering why burdock seeds stuck to his dog and his coat. Other bio-inspired products include adhesives, waterproof materials, and solar cells among many others. Scientists often look at nature to get ideas and designs for products that can help us. We call this study of nature biomimetics (see Resource section for further information). -

Occurrence of Reverse Side Effects in Corona Treatment of Dispersion
RESEARCH ARTICLE Occurrence of Reverse Side Effects in Corona Treatment of Dispersion-coated Paperboard and its Influence on Grease Barrier Properties PREFACE API 2015 Sami-Seppo Ovaska Ringaudas Rinkunas Lappeenranta University of Technology Vilnius University [email protected] [email protected] Tadeusz Lozovksi Robertas Maldzius Vilnius University & University of Bialystok Vilnius University Vilnius Branch [email protected] [email protected] Jonas Sidaravicius Leena-Sisko Johansson Vilnius Gediminas Technical University Aalto University [email protected] [email protected] Monika Österberg Kaj Backfolk Aalto University Lappeenranta University of Technology [email protected] [email protected] ABSTRACT The uncoated side of dispersion-barrier-coated paperboards was exposed to positive and negative direct current corona treatments in order to confirm the occurrence of backside treatment and clarify its effects on the usability of the paperboard. The main component of the coating dispersions was hydroxypropylated potato starch and the effects of talc and styrene-butadiene latex additions on backside treatment were evaluated. Coatings with a high talc proportion showed excellent initial grease resistance, but corona-induced strikethroughs caused a drastic decrease in grease penetration time. The root-mean-square roughness measurements revealed moderate surface roughening at the backside, indicating thus backside treatment. The alterations in surface free energies and rapeseed oil contact angles confirmed the occurrence of backside treatment. The high polarization potential of latex played a key role in these observations. At the same time, the inertity of talc had a stabilizing effect but it did not prevent backside treatment completely. X-ray photoelectron spectroscopy results verified that backside treatment occurs also when the barrier-coated side of the substrate is treated with corona, indicating that a dispersion coating layer does not prevent this undesired phenomenon. -

Oxygen-Reducing Enzymes in Coatings and Films for Active Packaging |
Kristin Johansson | Oxygen-reducing enzymes in coatings and films for active packaging | | Oxygen-reducing enzymes in coatings and films for active packaging Kristin Johansson Oxygen-reducing enzymes in coatings and films for active packaging Oxygen-reducing enzymes This work focused on investigating the possibility to produce oxygen-scavenging packaging materials based on oxygen-reducing enzymes. The enzymes were incorporated into a dispersion coating formulation applied onto a food- in coatings and films for packaging board using conventional laboratory coating techniques. The oxygen- reducing enzymes investigated included a glucose oxidase, an oxalate oxidase active packaging and three laccases originating from different organisms. All of the enzymes were successfully incorporated into a coating layer and could be reactivated after drying. For at least two of the enzymes, re-activation after drying was possible not only Kristin Johansson by using liquid water but also by using water vapour. Re-activation of the glucose oxidase and a laccase required relative humidities of greater than 75% and greater than 92%, respectively. Catalytic reduction of oxygen gas by glucose oxidase was promoted by creating 2013:38 an open structure through addition of clay to the coating formulation at a level above the critical pigment volume concentration. For laccase-catalysed reduction of oxygen gas, it was possible to use lignin derivatives as substrates for the enzymatic reaction. At 7°C all three laccases retained more than 20% of the activity they -
