Microfoam
Microfoam is finely textured milk used for making espresso-based coffee drinks, particularly those with latte art. It is typically made with the steam wand of an espresso machine, which pumps steam into a pitcher of milk. The opposite of microfoam is Macrofoam (also called ''dry'' foam, in contrast to the ''wet'' foam of microfoam), which has visibly large bubbles, a style of milk, traditionally used for cappuccinos. Characteristics Microfoam is shiny, slightly thickened, and should have microscopic, uniform bubbles. It is not as viscous or "foamy" as macrofoam – it is better described as "gooey" and resembles melted marshmallows or wet paint. There have been a variety of names used for this ideal standard, such as "microfoam", "velvet milk", "microbubbles", and so forth. Applications The decorative application of microfoam is called latte art, which involves making patterns in espresso-based drinks. Microfoam is essential for this as the microscopic bubbles give def ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latte Art
Latte art is a method of preparing coffee created by pouring microfoam into a shot of espresso and resulting in a pattern or design on the surface of the caffè latte, cappuccino or hot chocolate. It can also be created or embellished by simply "drawing" in the top layer of foam. Latte art is particularly difficult to create consistently, due to the demanding conditions required of both the espresso shot and milk. This, in turn, is limited by the experience of the barista and quality of the espresso machine. History Latte art developed independently in different countries, following the introduction of espresso and the development of microfoam, the combination of crema (which is an emulsion of coffee oil and brewed coffee) and microfoam allowing the pattern; it was initially developed in Italy. David Schomer describes pitcher-shaking in latte art as "quite standard in the world of Italian espresso preparation", indicating that it established in Italy by this time. In the Uni ...

Cappuccino
Cappuccino (, ; from German ) is an espresso-based coffee drink traditionally prepared with steamed milk, including a layer of milk foam. Variations of the drink involve the use of cream instead of milk, using non-dairy milk substitutes and flavoring with cocoa powder (in Europe and Australasia) or cinnamon (in the United States and South Korea). It is typically smaller in volume than that of a caffè latte, and topped with a thick layer of foam rather than being made with microfoam. The name comes from the Capuchin friars, referring to the color of their habits, and in this context, referring to the color of the beverage when milk is added in small portion to dark, brewed coffee (today mostly espresso). The physical appearance of a modern cappuccino with espresso crema and steamed milk is a result of a long evolution of the drink. The Viennese bestowed the name , possibly in the 18th century, on an early version that included whipped cream and spices. Later, the ...

Raw Milk
Raw milk or unpasteurized milk is milk that has not undergone pasteurization, a process of heating liquid foods to kill pathogens for safe consumption and extension of shelf life. Proponents of raw milk have alleged numerous purported benefits to consumption, including better flavor, better nutrition, contributions to the building of a healthy immune system and protection from allergies. However, no clear benefit to consumption has been found. In contrast, broad consensus in the medical community warns that there is increased risk of contracting dangerous milk borne diseases from these products. Substantial evidence of this increased risk, combined with a lack of any clear benefit, has led countries around the world to either prohibit the sale of raw milk or require warning labels on packaging when sold. In countries where it is available for sale, its availability and regulations around its sale vary. In the European Union, individual member states can prohibit or restrict the ...

Pasteurization
In food processing, pasteurization (American and British English spelling differences#-ise, -ize (-isation, -ization), also pasteurisation) is a process of food preservation in which packaged foods (e.g., milk and fruit juices) are treated with mild heat, usually to less than , to eliminate pathogens and extend shelf life. Pasteurization either destroys or deactivates microorganisms and enzymes that contribute to food spoilage or the risk of disease, including vegetative bacteria, but most Endospore, bacterial spores survive the process. Pasteurization 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 for food preservation and food safety. By the year 1999, most liquid products were heat treated in a co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latte Macchiato With Coffee Beans
Latte () or caffè latte (), also known as , or , is a coffee drink of Italian origin made with espresso and steamed milk, traditionally served in a glass. Variants include the chocolate-flavored '' caffè mocha'' or replacing the coffee with another beverage base such as masala chai (spiced Indian tea), mate, matcha, turmeric or rooibos; alternatives to milk, such as soy milk, coconut milk, almond milk or oat milk, are also used. The term comes from or (from , ); in English orthography, either or both words sometimes have an accent on the final ''e'' (a hyperforeignism in the case of *''latté''). In Northern Europe and Scandinavia, the term has traditionally been used for the combination of espresso and milk. In France, is from the original name of the beverage (caffè latte); a combination of espresso and steamed milk equivalent to a "latte" is in French called ( using cream instead of milk) and in German .

Powdered Milk
Powdered milk, also called milk powder, dried milk, or dry milk, is a manufactured dairy product made by evaporating milk to dryness. One purpose of drying milk is to preserve it; milk powder has a far longer shelf life than liquid milk and does not need to be refrigerated, due to its low moisture content. Another purpose is to reduce its bulk for the economy of transportation. Powdered milk and dairy products include such items as dry whole milk, nonfat (skimmed) dry milk, dry buttermilk, dry whey products and dry dairy blends. Many exported dairy products conform to standards laid out in ''Codex Alimentarius''. Powdered milk is used for food as an additive, for health (nutrition), and also in biotechnology (saturating agent). History and manufacture While Marco Polo wrote of Mongolian Tatar troops in the time of Kublai Khan who carried sun-dried skimmed milk as "a kind of paste", the first modern production process for dried milk was invented by the Russian doctor Osi ...

Metastable
In chemistry and physics, metastability is an intermediate energetic state within a dynamical system other than the system's state of least energy. A ball resting in a hollow on a slope is a simple example of metastability. If the ball is only slightly pushed, it will settle back into its hollow, but a stronger push may start the ball rolling down the slope. Bowling pins show similar metastability by either merely wobbling for a moment or tipping over completely. A common example of metastability in science is isomerisation. Higher energy isomers are long lived because they are prevented from rearranging to their preferred ground state by (possibly large) barriers in the potential energy. During a metastable state of finite lifetime, all state-describing parameters reach and hold stationary values. In isolation: *the state of least energy is the only one the system will inhabit for an indefinite length of time, until more external energy is added to the system (unique "absolu ...

Chemical Polarity
In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms. Molecules containing polar bonds have no molecular polarity if the bond dipoles cancel each other out by symmetry. Polar molecules interact through dipole-dipole intermolecular forces and hydrogen bonds. Polarity underlies a number of physical properties including surface tension, solubility, and melting and boiling points. Polarity of bonds Not all atoms attract electrons with the same force. The amount of "pull" an atom exerts on its electrons is called its electronegativity. Atoms with high electronegativitiessuch as fluorine, oxygen, and nitrogenexert a greater pull on electrons than atoms with lower electronegativities such as alkali metals and alkaline ...
