When heat is applied from the outside, as in retorting, the food nearest the can surfaces will answer
When heat is applied from the outside, as in retorting, the food nearest the can surfaces will reach sterilization temperature sooner than the food nearer the center of the can. The point in a can or mass of food which is last to reach the final heating temperature is designated the “cold point” within the can or pass.
What is heat preservation?
However, heat preservation of food generally refers to controlled processes that are performed commercially, such as balancing, pasteurizing, and canning.
What is pasteurization of food?
Pasteurization involves a comparatively low order of heat treatment, generally at temperature below the boiling point of water. Pasteurization treatments, depending on the food, have two different primary objectives. In the case of some products, notably milk and liquid eggs, pasteurization processes are specifically designed to destroy pathogenic organisms that may be associated with the food and could have public health significance. The second, more general, objective of pasteurization is to extend product shelf life from a microbial and enzymatic point of view. This is the objective when beer, wine, fruit juices and certain other foods are pasteurized. In the latter case, these foods would not be expected to be a source of pathogens, or would be protected by some other means of control. Pasteurized products will still contain many living organisms capable of growth of the order of thousands per milliliter or per gram –limiting the storage life compared to commercially sterile products. Pasteurization frequently is combined with another means of preservation, and many pasteurized foods must be stored under refrigeration. Pasteurized milk may be kept stored in a home refrigerator for a week or longer developing significant off-flavors. Stored at room temperature, however, pasteurized milk may spoil in a day or two. Pasteurization is not limited to liquid foods. A newer application is the steaming of oysters in the shell to reduce bacterial counts.

Thus, a thermal death curve established in a synthetic medium or in a given food generally is not applicable to a different food, and thermal death curves, to be valid, should be established in the specific food for which a heat process is being designed.
What fruit is good for hydration?
According to the Institute of Medicine, 20% of your daily water intake is sourced from food. Kiwi is a juicy fruit that not only aids in upping your hydration levels, it also holds 237 mg of an important electrolyte that is vital for muscle contraction: potassium. Among the many things that could go haywire in your system when you are on the verge of a heat stroke, dehydration is one of the top issues. Dehydration places stress on the heart and inhibits the kidney's ability to maintain the correct balance of electrolytes. Try eating a bowl of sliced banana and kiwi before your next outdoor workout for an ultimate boost in potassium.
How much heat does the body lose when dehydrated?
Think about it this way: The body cools itself by sweating, which normally accounts for 70 to 80% of the body's heat loss. If you are dehydrated, though, the rate at which you sweat slows and your body traps in the heat, instead.
Why is mint chip ice cream so popular?

Why is protective coating important?
Additionally, the use of a coating offers benefits such as the ability to salvage parts by re-heat treatment as well as the elimination of post-heat-treatment operations like grinding, shot blasting, acid pickling, etc. The coating process has simplified and accelerated many metallurgical heat-treatment operations, saving capital investment and reducing operating costs while improving quality.
What happens when steel is heated?
When steel is heated in an open furnace in the presence of air or products of combustion, two surface phenomena take place: oxidation and decarburization. The oxidation of steel is caused by the presence of oxygen, carbon dioxide and/or water vapor. The oxidation may manifest itself in a range from a tight, adherent straw-colored film that forms at a temperature of about 180°C (lower temperatures) to a loose, blue-black oxide scale (higher temperatures) with a resultant loss of metal.
Can you switch to steel grades that do not require heat treatment?
In rare cases, switching to steel grades that do not require heat treatment is possible. However, most of the mentioned solutions pose problems, extra costs or practical difficulties. The availability of capital and/or human resources to operate high-end furnaces is one major issue.

Why does heat transfer happen?
Heat transfer causes items to become the same temperature. Heat always moves from a warmer place to a cooler place, so cold items heat up to room temperature while warm items cool down to room temperature. The transfer of heat occurs consistently to make everything the same temperature. In your home, materials with shiny, ...
Why are roofs made of reflective metal?
In hot places where people cool their homes, roofs are sometimes made of reflective metal, using the principle of reflection to help the cooling process. You can experiment with this theory by placing a shiny, closed tin can outside in the sun. When you retrieve it, the can will be hot to the touch but the inside will remain cool.
