Ice cream

After the liquid nitrogen has completely vaporized, the remaining nitrogen bubbles are perfectly harmless, since nitrogen is the major component of air. Torgov, V.G. ; Tatarchuk, V.V. ; Druzhinina, I.A. ; Korda, T.M. The result, due to the extreme rapid cooling of the mixture, is a very smooth ice cream containing only small ice crystals. So far neither a pilot plant or full scale plant has been constructed to recover palladium, rhodium or ruthenium from nuclear wastes created by the use of nuclear fuel. The preparation is spectacular, since it results in a column of white condensed vapor, reminiscent of movie depictions of witches' cauldrons. This extraction operates by a solvation mechanism. Adding liquid nitrogen with the rest of the ingredients and stirring vigorously produces a very smooth ice cream. In this solvent extraction system the hydrocarbons of the diesel act as the diluent while the dialkyl sulfides act as the extractant.

This is an interesting legend, but it has not been substantiated. This has been proposed as a means of separating the fission product palladium from PUREX raffinate which comes from used nuclear fuel. Next door to the ice cream booth was the waffle booth; the waffle maker offered to make cones by rolling up his waffles; the new product became extremely popular at the fair and was widely copied by other vendors. Bad quality (high sulfur) diesel fuel has been used as a palladium extraction agent for the liquid-liquid extraction of this metal from nitric acid mixtures. According to legend, at the World's Fair an ice cream seller had run out of clean dishes, so he couldn't sell any more ice cream. This is the first time a maker has competed for the overall prize with a Diesel-fueled vehicle. Louis World's fair in 1904. Audi will fight for the overall win at the 24 Hours of Le Mans in 2006 with the Diesel-powered R10.

The popularity of selling ice cream in cones increased greatly during the St. Westport claims to have invented a process called Westport-Cycle ^[5] with comparable efficiency using natural gas and petrodiesel. She patented and manufactured an ice cream maker and was the first person to suggest using liquid gases to freeze ice cream after seeing a demonstration at the Royal Institution. That car and a later Cummins Diesel Special are on display at the Indianapolis Motor Speedway Hall of Fame Museum^[4]. Agnes Marshall was a celebrated cookery writer of her day and helped to popularise ice cream. The following year Dave Evans drove his Cummins Diesel Special to a nonstop finish in the Indianapolis 500, the first time a car had completed the race without a pit stop. Mrs Marshall's Cookery Book, published in 1888, endorsed serving ice cream in cones, but the idea probably predated that cookbook. This feat helped to prove the usefulness of the internal combustion engine.

In the UK this is a minimum of 5% fat and a minimum of 2.5% milk protein (Schedule 8, the Food Labelling Regulations 1996) [1] (pdf). The trip was from Indianapolis to New York City - a distance of nearly 800 miles (1300 km). In apparent contradiction to the above paragraph, the Ice Cream Alliance Ltd, a trade association for the UK ice-cream industry, says that: "It is necessary for a manufacturer to be aware of the compositional requirements of the country in which he intends to sell his ice cream. The very first diesel-engine automobile trip was completed on January 6, 1930. However, ice cream sold as dairy ice cream must contain milk fat, and many companies make sure that dairy is prominently displayed on their packaging or businesses. In 1931, Walter Lees and Fredrick Brossy set the nonstop flight record flying a Bellanca powered by a Packard Diesel for 84h 32m. Instead, it is made with vegetable oil, usually hydrogenated palm kernel oil. Woolson was fitted to a Stinson X7654, and in 1929 it was flown 1000 km non-stop from Detroit to Langley, Virginia (near Washington, D.C.).

In the United Kingdom, much of the lower-priced ice cream sold, including that from some ice cream vans, has no milk or milk solids content at all. A Packard diesel motor designed by L.M. Italian ice-cream parlours (Eisdielen) are common and popular in Germany where many Italians have immigrated and set up business. Packard diesel motors were used in aircraft as early as 1927, and Charles Lindbergh flew a Stinson SM1B with a Packard Diesel in 1928. Before the cone became popular for serving ice cream, Italian street vendors would serve the ice cream in a small glass dish referred to as a 'penny lick' or wrapped in waxed paper and known as a hokey-pokey (possibly a corruption of the Italian "ecco un poco" - "here is a little"). Diesel engines are used in cars, trucks, motorcycles, boats and locomotives. Ice cream today is a traditional dessert in Italy, where it is still mostly hand-made, though one of the most known ice-cream machine makers is the Carpigiani. Rudolf Diesel originally designed the diesel engine to use coal dust as a fuel, but oil proved more effective.

Per Capita, Australians consume the most amount of ice cream than anywhere else. Diesel is used in diesel engines, a type of internal combustion engine. For example, Japanese mochi ice cream is now popular in California, even outside Japanese restaurants and Little Tokyos. In India, taxes on diesel fuel are lower than on gasoline as majority of the transportation, that transports grains and other essential commodities across the country, runs on diesel. Globalization has made available ice-cream styles from around the world. The term DERV (short for "diesel engined road vehicle") is also used in the UK as a synonym for diesel fuel. Both Ben and Jerry's and Häagen-Dazs fall into this category. Diesel fuel, or Marked Gas Oil is dyed green in the Republic of Ireland.

The 1990s saw a return of the older, thicker, ice creams being sold as "premium" varieties. Also, in the United Kingdom and Northern Ireland it is known as red diesel, and is also used by agricultural vehicles. The ice cream was also very popular amongst consumers who preferred the light flavour, and most major ice cream brands now use this manufacturing process. This untaxed diesel is also dyed red for identification purposes, and should a person be found to be using this untaxed diesel fuel for a typically taxed purpose (such as "over-the-road", or driving use), the user can be fined $10,000 USD on the spot. This allowed manufacturers to use less of the actual ingredients, saving money. Similarly, "untaxed" diesel is available in the United States, which is available for use primarily in agricultural applications such as for tractor fuel. A chemical research team in Britain (of which a young Margaret Thatcher was a member) discovered a method of doubling the amount of air in ice cream. In Europe, the United States and Canada, taxes on diesel fuel are higher than on heating oil due to the fuel tax, and in those areas, heating oil is marked with fuel dyes and trace chemicals to prevent and detect tax fraud.

One important development in the 20th century was the introduction of soft ice cream. Diesel fuel is very similar to heating oil which is used in central heating. Howard Johnson's restaurants advertised "a world of 28 flavors." Baskin-Robbins made its 31 flavors ("one for every day of the month") the cornerstone of its marketing strategy; the company now boasts that it has developed over 1000 varieties. Due to the purity of the source, it has a higher quality than petrodiesel. Vendors often competed on the basis of variety. Paraffin biodiesel also exists. Soon there was an explosion of ice cream stores and of flavors and types. However, biodiesel has combustion properties very similar to regular diesel, including combustion energy and cetane ratings.

Ice cream became extremely popular throughout the world in the second half of the 20th Century after cheap refrigeration became common and wages became high enough to indulge in such minor luxuries. Chemically, most biodiesel consists of alkyl (usually methyl) esters instead of the alkanes and aromatic hydrocarbons of petroleum derived diesel. During Prohibition, the soda fountain was promoted as an alternative to the saloon. A small percentage of biodiesel can be used as an additive in low-sulfur formulations of diesel to increase the lubricating ability that is lost when the sulfur is removed. Around the turn of the 20th Century, the ice cream soda was consumed at the soda shop, the soda fountain, and the ice cream parlor. There have been reports that a diesel-biodiesel mix results in lower emissions than either can achieve alone. Retail storefront outlets developed as chains of ice cream stores, such as Baskin Robbins. This can be overcome by using a biodiesel/petrodiesel blend, or by installing a small heater in your fuel system, but this is only nessecary during the colder months.

The history of ice cream in the 20th century is one of great change and increase in availability and popularity. Biodiesel has a lower gel point than regular diesel, but is comparable to diesel #2. Both the ice cream cone and banana split were popularized in the first years of the 20th century. It can also be mixed with petrodiesel in any amount in modern engines, though when first using it , the solvent properties of the fuel tend to clear out all the garbage that has built up from the petrodiesel and can clog fuel filters. Some versions say that the sundae was invented to circumvent the Blue Laws, which forbade serving sodas on Sunday. Biodiesel is a non-fossil fuel alternative to petrodiesel. Several men claimed to have created the first sundae, but there is no solid evidence to back up any of their stories. Biodiesel can be obtained from vegetable oil and animal fats (bio-lipids, using transesterification).

The ice cream sundae originated in the late 19th Century. Such synthetic diesel has 30% less particulate emissions than conventional diesel (US- California) ^[3]. It was probably invented by Robert Green in 1874, although there is no conclusive evidence to prove his claim. Synthetic diesel may also be produced out of natural gas in the GTL process. This was followed by the invention of the ice cream soda. ^[2] Other attempts use enzymatic processes and are also economic in case of high oil prices. In 1843 Nancy Johnson became the first American to patent a handcranked ice cream freezer. After purification the so called Fischer Tropsch process is used to produce synthetic diesel.

Dolley Madison is also closely associated with the early history of ice cream in the United States. Wood, straw, corn, garbage, and sewage-sludge may be dried and gasified. Ben Franklin, George Washington, and Thomas Jefferson were among the elite who regularly ate and served ice cream. C₁₀H₂₂ to C₁₅H₃₂. Confectioners, many of whom were Frenchmen, sold ice cream at their shops in New York and other cities during the Colonial era. Petroleum derived diesel is composed of about 75% saturated hydrocarbons (primarily paraffins including n, iso, and cycloparaffins), and 25% aromatic hydrocarbons (including naphthalenes and alkylbenzenes).^[1] The average chemical formula for common diesel fuel is C₁₂H₂₆, ranging from approx. Contemporary western-style ice cream, however was probably “discovered” in the 1600’s, and was introduced to the United States by colonists who brought their ice cream recipes with them. In the maritime field various grades of diesel fuel are used.

Snow-cones, made from balls of crushed ice topped with sweet syrup served in a paper cone, are consumed in many parts of the world. Diesel contains approximately 18% more energy per unit of volume than gasoline, which, along with the greater efficiency of diesel engines, contributes to fuel economy (distance traveled per volume of fuel consumed). People living directly alongside snow and ice have probably always put sweet things like honey and fruit juice on frozen water for variety, as some still do to this day. Biodiesel is an effective lubricity additive. While it was not yet ice cream per se, some examples of early pre-planned ice dishes include the Roman emperor Nero (37-68) who is said to have ordered ice to be brought from the mountains and combined with fruit toppings, and King Tang (618-97) of the Shang Dynasty who is said to have had a method of creating ice and milk concoctions. However, lowering sulfur also reduces the lubricity of the fuel, meaning that additives must be put into the fuel to help lubricate engines. Ice cream most likely did originate in China, but it is unknown how and when the idea made its way into the Western world. It prevents the use of catalytic diesel particulate filters to control diesel particulate emissions, as well as more advanced technologies, such as nitrogen oxide (NOx) adsorbers (still under development), to reduce emissions.

There is, however, no historical evidence to support this legend, which first appeared during the 19th century and was probably created by imaginative ice cream vendors. High levels of sulfur in diesel are harmful for the environment. Charles I was supposedly so impressed by the "frozen snow" that he offered his own ice cream maker a lifetime pension in return for keeping the formula secret, so that ice cream could be a royal prerogative. diesel fuel typically also has a lower cetane number (a measure of ignition quality) than European diesel, resulting in worse cold weather performance and some increase in emissions. Catherine de Medici's Italian chefs are said to have carried the ice cream recipe to France when she went there in 1533 to marry the Duc d'Orléans. U.S. According to legend, Marco Polo saw ice cream being made on his trip to China, bringing the recipe home to Italy with him on his return. In contrast, the United States has long had "dirtier" diesel, although more stringent emission standards have been adopted with the transition to ultra-low sulfur diesel (ULSD) occurring in 2006 (see also diesel exhaust).

It is believed that the Song dynasty (宋朝) was the time when people began putting fruit juice in the water used to create the ice; milk was beginning to be used in the Yuan dynasty (元朝). In Europe, emission standards and preferential taxation have both forced oil refineries to dramatically reduce the level of sulfur in diesel fuels. The Chinese put sugar in the ice and sold them as food during the summer. Diesel fuel, however, often contains higher quantities of sulfur. Saltpeter was used for the production of gunpowder in China, and the Chinese discovered that saltpeter in water caused the water to absorb heat, thus creating ice in summer. Diesel is generally simpler to refine than gasoline and often costs less (although price fluctuations often mean that the inverse is true; for example, the cost of diesel traditionally rises during colder months as demand for heating oil, which is refined much the same way, rises). There are several popular legends surrounding the discovery of ice cream. When burnt diesel typically releases about 147,000 British thermal units (BTU) per US gal (40.9 megajoules (MJ) per liter), whereas gasoline releases 125,000 BTUs per US gal (34.8 MJ/l), also about 15% less.

There are many kinds of Arabian Ice cream "Butha" we can find in the market they have advantages of being healthy and fresh as they are made of fresh milk. Diesel typically weighs about 7.1 pounds (lb) per US gallon (gal) (850 grams per liter (g/l)), whereas gasoline weighs about 6.0 lb per US gal (720 g/l), or about 15% less. Arabs introduced gelato to the west through Sicily. Petro Diesel is considered to be a fuel oil and is about 18% denser than gasoline. It was made of a chilled syrup or milk with fruits and some nuts. As a hydrocarbon mixture, it is obtained in the fractional distillation of crude oil between 250 °C and 350 °C at atmospheric pressure. Ice cream was the favourite dessert for the Caliphs of Baghdad, Arabs were the first to make it or at least commercially as there were ice cream factories in the 10th century and the first to sugar Ice cream, it was sold in markets of all Arab cities in the past. Diesel is produced from petroleum, and is sometimes called petrodiesel (or, less seriously, dinodiesel) when there is a need to distinguish it from diesel obtained from other sources.

See also Kulfi, another originally Persian form of the ice cream. . 1 2. The term typically refers to fuel that has been processed from petroleum, but increasingly, alternatives such as biodiesel or biomass to liquid (BTL) or gas to liquid (GTL) diesel that are not derived from petroleum are being developed. The mix is then frozen, and mixed with rosewater and lemons, before serving. Diesel or Diesel fuel is a specific fractional distillate of fuel oil (mostly petroleum) that is used as fuel in a diesel engine invented by German engineer Rudolf Diesel. The treat, widely made today in Iran, is called "faludeh", which is made from starch (wheat, probably), spun in a kind of sieve-like contraption which produces threads or drops of the batter, which are boiled in water.

The ice was then mixed in with saffron, fruits, and various other flavors. ^  http://www.westport.com/expertise/westport_cycle.php. The storages worked by using tall windcatchers that kept the sub-level storage space at frigid temperatures. URL accessed on December 5, 2005.. These storages kept ice brought in from the winter or from nearby mountains well into the summer. ^  Indianapolis Motor Speedway. The Persians had already mastered the technique of storing ice inside giant naturally cooled refrigerators known as yakhchals. URL accessed on December 5, 2005..

In 400 BCE Persia, a special chilled pudding-like dish, made of rosewater and vermicelli, working out as something like a cross between a sorbet and a rice pudding, was served to the royalty during summers. ^  SYNTHETIC DIESEL FUEL. On the Mediterranean coast of Turkey, ice cream is sometimes sold to beachgoers from small powerboats equipped with chest freezers. URL accessed on December 5, 2005.. There are even some ice-cream distributors who sell ice-cream products door-to-door from travelling refrigerated vans, often equipped with speakers playing a children's music tune. ^  http://www.fas.usda.gov/pecad/highlights/2005/01/btl0104/syntheticdiesel.htm. Ice cream can be purchased in large tubs and squrounds from supermarkets/grocery stores, in smaller quantities from ice cream shops, convenience stores, and milk bars, and in individual serves from small carts or vans at public events and places. Department of Health and Human Services, Public Health Service.

Today, ice cream is enjoyed around the world on a daily basis thanks to mass production. Atlanta, GA: U.S. The most common method for producing ice-cream at home is to use an ice-cream machine, generally an electrical device that churns the ice cream while refrigerated inside a household freezer or using ice and salt for cooling. Toxicological profile for fuel oils. The development of industrial refrigeration by German engineer Carl von Linde during the 1870s obviated the cutting and storing of natural ice and then the continuous-process freezer was perfected in 1926, allowing commercial mass production of ice cream and the birth of the modern ice-cream industry. 1995. He sold his business to Borden. ^ Agency for Toxic Substances and Disease Registry (ATSDR).

Many were still around well into the 20th century. Fussell opened ice cream parlors as far west as Texas. This allowed the previously expensive concoction to be offered at prices everyone could afford. An unstable demand for his milk led him to mass produce ice cream.

The world's first commercial ice-cream factory was opened in Baltimore, Maryland in 1851, by Jacob Fussell, a dairy farmer. The hand-cranked churn, which still used ice and salt for cooling, was invented by an American named Nancy Johnson in 1846, making production simpler. Ice cream was made by hand in a large bowl surrounded by packed ice and salt. Ice was cut commercially from lakes and ponds during the winter and stored in large heaps in holes in the ground, insulated by straw.

The dissolving of salt in water is endothermic and the salt allows liquid water to be below the freezing point of pure water, allowing the immersed container with cream to make better contact with the melted water/ice mixture. The temperature was reduced by placing the ice cream mixture into a container that was immersed in a mixture of crushed ice and salt. The making of ice cream was originally a laborious process. Before the development of modern refrigeration ice cream was a luxury item reserved for special occasions.

. Many people also like ice cream sundaes, which often have ice cream, hot fudge, nuts, whipped cream, cherries and other toppings of their choice. Some of the most popular ice cream flavours in supermarkets are vanilla, chocolate, strawberry, and Neapolitan (a combination of the three). Ice-creams come in a wide variety of flavours, often with additives such as chocolate flakes or chips, nuts, fruit, and small candies/sweets.

The use of stabilizers rather than actual cream and the incorporation of air also decreases the fat and caloric content of less expensive ice creams, making them more appealing to those on diets. Since ice cream is sold by volume, it's economically advantageous for producers to reduce the density of the product in order to cut costs. Generally speaking, the finest ice creams have less than 30% air, but more than 15%. Artisan-produced ice creams, such as Berthillon's, often contain very little air, although some is necessary to produce the characteristic creamy texture of the product.

Generally, the less expensive the ice-cream, the lower the quality of the ingredients (for example, replacing vanilla bean with artificial vanillin), and the more air is incorporated, sometimes as much as 50% of the total volume. These ingredients make up the solid part of the ice cream, but only a portion of the final volume, the remainder being air incorporated during the whipping process. Modern commercial ice cream is made from a mixture of ingredients:. Governments often regulate the use of these terms based on quantities of ingredients.

Frozen custard, ice milk, sorbet and other similar products are often also called ice cream. Although the term "ice cream" is sometimes used to mean frozen desserts and snacks in general, it is usually reserved for frozen desserts and snacks made with a high percentage of milk fat. This mixture is cooled while stirring to prevent large ice crystals from forming. Ice cream (originally iced cream) is a frozen dessert made from dairy products such as cream (or equivalents), combined with flavourings and sweeteners.

Kulfi: brought to Pakistan and India by the Mughals from Persia during the 1500s, later brought to the West as the result of colonialism and immigration. Pop: frozen fruit puree, fruit juice, or flavored sugar water on a stick or in a flexible plastic sleeve. Sorbet: fruit puree and no milk products. Sherbet: 1-2% milk fat and more sweetener than ice cream.

Gelato: an Italian frozen dessert. Mellorine: non-dairy, with vegetable fat substituted for milk fat. Frozen yogurt. Frozen custard: at least 10% milk fat and at least 1.4% egg yolk and much less air beaten into it, similar to Gelato, fairly rare.

Ice milk: less than 10% milk fat and lower sweetening content, sold as low-fat ice cream in the United States. 55%-64% water which comes from milk solids or other ingredients. 0.2-0.5% stabilizers and emulsifiers e.g., agar or carrageenan extracted from seaweed. 12-16% sweeteners: usually a combination of sucrose and/or glucose-based corn syrup sweeteners.

9-12% milk solids-not-fat: this component, also known as the serum solids, contains the proteins (caseins and whey proteins) and carbohydrates (lactose) found in milk. 10-16% milk fat.
