Pasteurized Eggs
Pasteurized eggs are eggs that have been pasteurized in order to reduce the risk of food-borne illness in dishes that are not cooked or are only lightly cooked. They may be sold as liquid egg products or pasteurized in the shell. Rationale The 2013 United States Food and Drug Administration Food Code defines regular shell eggs as a potentially hazardous food, i.e., “a food that requires time/temperature control for safety (TCS) to limit pathogenic microorganism growth or toxin formation.” All egg products sold in the U.S that are pasteurized due to the risk of food-borne illnesses are done per U.S. Department of Agriculture rules. They also do not allow any egg products to be sold without going through the process of pasteurization. They also do not recommend eating shell eggs that are raw or undercooked due to the possibility that Salmonella bacteria may be present. Because of the risk of food-borne illness caused by ''Salmonella'' bacteria that may be present in raw eg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pasteurized Egg White
Pasteurization or pasteurisation is a process of food preservation in which packaged and non-packaged foods (such as milk and fruit juices) are treated with mild heat, usually to less than , to eliminate pathogens and extend shelf life. The process is intended to destroy or deactivate microorganisms and enzymes that contribute to food spoilage or risk of disease, including vegetative bacteria, but most bacterial spores survive the process. The process is named after the French microbiologist Louis Pasteur whose research in the 1860s demonstrated that thermal processing would deactivate unwanted microorganisms in wine. Spoilage enzymes are also inactivated during pasteurization. Today, pasteurization is used widely in the dairy industry and other food processing industries to achieve food preservation and food safety. By the year 1999, most liquid products were heat treated in a continuous system where heat can be applied using a plate heat exchanger or the direct ...

Mayonnaise
Mayonnaise (; ), colloquially referred to as "mayo" , is a thick, cold, and creamy sauce or dressing commonly used on sandwiches, hamburgers, composed salads, and French fries. It also forms the base for various other sauces, such as tartar sauce, fry sauce, remoulade, salsa golf, and rouille. Mayonnaise is an emulsion of oil, egg yolk, and an acid, either vinegar or lemon juice; there are many variants using additional flavorings. The color varies from near-white to pale yellow, and its texture from a light cream to a thick gel. Commercial eggless imitations are made for those who avoid chicken eggs because of egg allergies, to limit dietary cholesterol, or because they are vegans. History ''Mayonnaise'' is a French cuisine appellation that seems to have appeared for the first time in 1806. The hypotheses invoked over time as to the origin(s) of mayonnaise have been numerous and contradictory. Most hypotheses do however agree on the geographical origin of the sauce ...

Powdered Eggs
A powdered egg is a fully dehydrated egg. Most powdered eggs are made using spray drying in the same way that powdered milk is made. The major advantages of powdered eggs over fresh eggs are the reduced weight per volume of whole egg equivalent and the shelf life. Other advantages include smaller usage of storage space, and lack of need for refrigeration. Powdered eggs can be used without rehydration when baking, and can be rehydrated to make dishes such as scrambled eggs and omelettes. History Dehydrated eggs advertisements appeared in the late 1890s in the United States. Powdered eggs appear in literature as a staple of camp cooking at least as early as 1912.''Along the Mohawk trail; or, Boy scouts on Lake Champlain'' Percy Keese Fitzhugh, Grosset & Dunlap, 1912, ...

Food Safety News
''Food Safety News (FSN)'' is an online news publication focusing on food safety. It was founded in 2009 by Bill Marler, a lawyer and food safety advocate. Marler is the Managing Partner of Marler Clark, a Seattle, Washington, law firm that specializes in foodborne illness cases. He said that ''Food Safety News'' was created to "fill a void" left by print and broadcast Broadcasting is the distribution of audio or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum ( radio waves), in a one-to-many model. Broadcasting began ... media as budgetary constraints led to "dedicated reporters on the food, health and safety beats... being reassigned or seeing their positions disappear altogether." The site provides daily news coverage of foodborne illness outbreaks and investigations, food recalls, food technology innovations, and victim profiles.

Nitrogen
Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N2, a colorless and odorless diatomic gas. N2 forms about 78% of Earth's atmosphere, making it the most abundant uncombined element. Nitrogen occurs in all organisms, primarily in amino acids (and thus proteins), in the nucleic acids ( DNA and RNA) and in the energy transfer molecule adenosine triphosphate. The human body contains about 3% nitrogen by mass, the fourth most abundant element in the body after oxygen, carbon, and hydrogen. The nitrogen cycle describes the movement of the element from the air, into the biosphere and organic compounds, then back into the atmosphere. Many indus ...

Reactive Oxygen Species
In chemistry, reactive oxygen species (ROS) are highly reactive chemicals formed from diatomic oxygen (). Examples of ROS include peroxides, superoxide, hydroxyl radical, singlet oxygen, and alpha-oxygen. The reduction of molecular oxygen () produces superoxide (), which is the precursor to most other reactive oxygen species: :O2 + e^- -> \ ^\bullet O2- Dismutation of superoxide produces hydrogen peroxide (): :2 H+ + \ ^\bullet O2^- + \ ^\bullet O2^- -> H2O2 + O2 Hydrogen peroxide in turn may be partially reduced, thus forming hydroxide ions and hydroxyl radicals (), or fully reduced to water: :H2O2 + e^- -> HO^- + \ ^\bullet OH :2 H+ + 2 e- + H2O2 -> 2 H2O In a biological context, ROS are byproducts of the normal metabolism of oxygen. ROS have roles in cell signaling and homeostasis. ROS are intrinsic to cellular functioning, and are present at low and stationary levels in normal cells. In plants, ROS are involved in metabolic processes related to photoprotection and toleran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ozone
Ozone (), or trioxygen, is an inorganic molecule with the chemical formula . It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope , breaking down in the lower atmosphere to (dioxygen). Ozone is formed from dioxygen by the action of ultraviolet (UV) light and electrical discharges within the Earth's atmosphere. It is present in very low concentrations throughout the latter, with its highest concentration high in the ozone layer of the stratosphere, which absorbs most of the Sun's ultraviolet (UV) radiation. Ozone's odour is reminiscent of chlorine, and detectable by many people at concentrations of as little as in air. Ozone's O3 structure was determined in 1865. The molecule was later proven to have a bent structure and to be weakly diamagnetic. In standard conditions, ozone is a pale blue gas that condenses at cryogenic temperatures to a dark blue liquid and finally a violet-black soli ...

Separating Eggs
Separating eggs is a process, generally used in cooking, in which the egg yolk is removed from the egg white. This allows one part of the egg to be used without the other part, or each part to be treated in different ways. Recipes for custard call for egg yolks, for example. The most common reason for separating eggs is so the whites can be whipped. Also, because cholesterol is only found in the yolk, using only egg whites in a recipe will drastically reduce its cholesterol content. Technique All methods for separating eggs make use of the fact that the yolk can hold itself together while the white is more runny. Since the yolks of older eggs are more watery, which makes separation difficult, it is best to begin with the freshest eggs available. Although many recipes require eggs to be at room temperature Colloquially, "room temperature" is a range of air temperatures that most people prefer for indoor settings. It feels comfortable to a person when they are wearing typica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Cream
Ice cream is a sweetened frozen food typically eaten as a snack or dessert. It may be made from milk or cream and is flavoured with a sweetener, either sugar or an alternative, and a spice, such as cocoa or vanilla, or with fruit such as strawberries or peaches. It can also be made by whisking a flavored cream base and liquid nitrogen together. Food coloring is sometimes added, in addition to stabilizers. The mixture is cooled below the freezing point of water and stirred to incorporate air spaces and to prevent detectable ice crystals from forming. The result is a smooth, semi-solid foam that is solid at very low temperatures (below ). It becomes more malleable as its temperature increases. The meaning of the name "ice cream" varies from one country to another. In some countries, such as the United States, "ice cream" applies only to a specific variety, and most governments regulate the commercial use of the various terms according to the relative quantities of the main in ...

Eggnog
Eggnog (), historically also known as a milk punch or an egg milk punch when alcoholic beverages are added, is a rich, chilled, sweetened, dairy-based beverage. It is traditionally made with milk, cream, sugar, egg yolks, and whipped egg whites (which gives it a frothy texture, and its name). Distilled spirits such as brandy, rum, whisky or bourbon are often a key ingredient. Throughout Canada, the United States and some European countries, eggnog is traditionally consumed over the Christmas season, from late October until the end of the holiday season. A variety called ponche crema has been made and consumed in Venezuela and Trinidad since the 1900s, also as part of the Christmas season. During that time, commercially prepared eggnog is sold in grocery stores in these countries. Eggnog is also homemade using milk, eggs, sugar, and flavorings, and served with cinnamon or nutmeg. While eggnog is often served chilled, in some cases it is warmed, particularly on cold days (simila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meringue
Meringue (, ; ) is a type of dessert or candy, often associated with Swiss, French, Polish and Italian cuisines, traditionally made from whipped egg whites and sugar, and occasionally an acidic ingredient such as lemon, vinegar, or cream of tartar. A binding agent such as salt, flour or gelatin may also be added to the eggs. The key to the formation of a good meringue is the formation of stiff peaks by denaturing the protein ovalbumin (a protein in the egg whites) via mechanical shear. Its flavorants are vanilla, a small amount of apple juice, or orange juice, although if extracts of these are used and are based on an oil infusion, an excess of fat from the oil may inhibit the egg whites from forming a foam. They are light, airy and sweet confections. Homemade meringues are often chewy and soft with a crisp exterior, while many commercial meringues are crisp throughout. A uniform crisp texture may be achieved at home by baking at a low temperature () for an extended period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
