How to Make a Smell Training Kit July 3 2019
Some frequently asked questions Q. How much oil do I need in the jar? A. You only need enough to saturate the paper disc. Any more than that is just a waste of the oil. Q. I can’t smell anything! Have I done it wrong? A. Probably not. If you’ve followed the directions, your jars should be plenty “smelly”. The saturated disc, kept in the closed space with the cap on the jar, creates a really strong smell. If you are not smelling it now, give it time. Q. Can I put my nose all the way into the jar? A. That is not recommended. Keep the tip of your nose out of the jar. Q. What if I want to reuse the jar, but with different oils? A. You can do this, but you need to give the jars a really Smell Training Kits good clean with hot water and soap. Let them dry thoroughly. The lid will smell like the previous oil (not great, but you could improvise and remove the inside of the cap, which is made of white, plastic coated paper). Then cut yourself some new watercolour paper discs and make up the new jars. How to make your own Q. Can I use cotton pads inside the jars? A. Cotton pads are not recommended. They make a great place for bacteria to collect. Watercolour paper is absorbent, but does not harbour bacteria.

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. -

More Than Just Dry Air
More than just dry air Rich Heimsch To avoid the damage of micro-cracks and delamination during the processing of electronic components, appropriate environmental storage is essential. The introduction of lead-free soldering and the associated higher processing temperatures involved makes moisture management even more critical. In this collection of articles published in SMT 007 magazine, Rich Heimsch of Super Dry Totech discusses the issues of moisture damage and specialized moisture management and tracking technology for Components and PCBs.

Frozen Foods Handout
Choosing Frozen Foods Don’t get left in the cold! Frozen foods can be healthy, quick choices if they are chosen carefully. Frozen foods are easy to store and often very affordable. Frozen fruits and vegetables are usually just as nutritious as fresh because they are picked at peak freshness. Learn about making the most of healthy, frozen foods. Frozen Food Tips Skip the frozen meals. Instead buy frozen foods that are made from just a few ingredients such as fruits, vegetables, !sh, lean meats, and whole grains. Look for frozen foods without added sugar, salt, or fat. Check the nutrition facts label! Aim for foods that are minimally processed. Foods that are less processed tend to be healthier. Great examples are vegetables that have just been cut up and steamed or raw frozen fruits. Keep healthy foods in your freezer at all times. This makes it easy to put together healthy meals with ingredients you have. Prevent freezer burn. Wrap foods well in a double layer of plastic wrap or aluminum foil, and seal them in freezer bags. Prepare and eat foods quickly after opening. Store frozen fruits and vegetables at 0°F. This helps prevent nutrient loss. Keep a list of freezer foods on hand, and label foods well. It can be easy to lose track of what is there! Cooking with frozen foods is easy! Mix frozen fruit into oatmeal, baked goods, yogurt or smoothies. Add some extra frozen vegetables to soups, stews, casseroles, or pasta. Choosing frozen foods! Vegetables Fruits What to look for: What to look for: ☐ No added salt ☐ No added sugar ☐ No breading -

THE FLAVOR APPRENTICE SHELF LIFE FLAVOR INFORMATION Concentrated Flavors Do Not Spoil, Or Go Rancid, Like Fruit Juices Can., So
THE FLAVOR APPRENTICE SHELF LIFE FLAVOR INFORMATION Concentrated flavors do not spoil, or go rancid, like fruit juices can., so they do not really have an "expiration date". But under certain conditions they can change. In other words, you will notice that a "fresh" bottle might seem different from an older bottle. Basically, what my flavor manufacturer tells me is that the flavors can have a very long shelf life, when they are not continuously opened and are stored in glass. It is not necessary to store them in the refrigerator, but I don't think that this would hurt them. But sometimes refrigeration can cause re-crystallization of flavors that have a lot of the crystals like ethyl maltol in them. Please refer to our COA for our shelf life statement. Here's some background. Every concentrated flavor is a mixture of raw materials, and every flavor blend can act differently. For example flavors that have a vanilla characteristic are going to have slightly different storage capabilities than fruit flavors. Here's the reason. Vanilla and caramel flavors are mostly made of large molecules like vanillin, ethyl vanillin , etc. These molecules are not very volatile, and tend not to escape the bottle when you open it. They will be fairly stable. Fruit flavors, on the other hand, are made of much smaller molecules in general. Whenever you open a bottle, it's the lightest and smallest molecules that escape and reach your nose quickly. Over time when you open a bottle over and over again more and more proportion of these lighter molecules leave the bottle and eventually the character of the flavor will be changed. -
Biodegradable Packaging Materials from Animal Processing Co-Products and Wastes: an Overview
polymers Review Biodegradable Packaging Materials from Animal Processing Co-Products and Wastes: An Overview Diako Khodaei, Carlos Álvarez and Anne Maria Mullen * Department of Food Quality and Sensory Science, Teagasc Food Research Centre, Ashtown, Dublin, Ireland; [email protected] (D.K.); [email protected] (C.Á.) * Correspondence: [email protected]; Tel.: +353-(1)-8059521 Abstract: Biodegradable polymers are non-toxic, environmentally friendly biopolymers with con- siderable mechanical and barrier properties that can be degraded in industrial or home composting conditions. These biopolymers can be generated from sustainable natural sources or from the agri- cultural and animal processing co-products and wastes. Animals processing co-products are low value, underutilized, non-meat components that are generally generated from meat processing or slaughterhouse such as hide, blood, some offal etc. These are often converted into low-value products such as animal feed or in some cases disposed of as waste. Collagen, gelatin, keratin, myofibrillar proteins, and chitosan are the major value-added biopolymers obtained from the processing of animal’s products. While these have many applications in food and pharmaceutical industries, a sig- nificant amount is underutilized and therefore hold potential for use in the generation of bioplastics. This review summarizes the research progress on the utilization of meat processing co-products to fabricate biodegradable polymers with the main focus on food industry applications. In addition, the factors affecting the application of biodegradable polymers in the packaging sector, their current industrial status, and regulations are also discussed.

Abstract: Freezing is a well-established preservation method used to maintain the freshness of perishable food products during storage, transportation and retail distribution; however, food freezing is a complex process involving simultaneous heat and mass transfer and a progression of physical and chemical changes. This could affect the quality of the frozen product and increase the percentage of drip loss (loss in flavor and sensory properties) during thawing. Numerical modeling can be used to monitor and control quality changes during the freezing and thawing processes.

Influence of Storage Temperature on Changes in Frozen Meat Quality
Influence of Storage Temperature on Changes in Frozen Meat Quality Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Jeffrey Caminiti Graduate Program in Food Science and Technology The Ohio State University 2018 Thesis Committee Dennis Heldman, Advisor Macdonald Wick, Advisor Christopher Simons 1 Copyrighted by Jeffrey T. Caminiti 2018 2 Abstract Food is often frozen to prolong shelf-life by maintaining safety and high quality. Since frozen food storage is energy intensive, careful evaluation of the influence of storage temperature on shelf-life is needed. Although the shelf-life of frozen meat at - 18°C may be desirable, the influence of slightly higher storage temperatures on shelf-life have not been thoroughly investigated. Through the understanding of quality degradation reactions and their dependence on temperature, an argument may be made to encourage storage at a more sustainable temperature. The objective was to evaluate the effect of storage temperature on frozen chicken and ground beef quality attributes to identify improved energy efficiencies during storage. Whole muscle chicken breasts (pectoralis major) were frozen to -20°C [-4°F] then stored at -10°C [14°F], -15°C [5°F], or -20°C for one year. In a completely randomized design monthly quality testing was conducted on three replicates thawed overnight to 4°C. Quality analysis consisted of % drip loss measurements, water holding capacity (WHC), moisture content (WBMC), lipid oxidation by 2-thiobarbituric acid assay (TBARS), color, and cooked texture analysis by Blunt Meullenet-Owens Razor Shear (BMORS). -
