Styrofoam Cup
A foam food container is a form of disposable food packaging for various foods and beverages, such as processed instant noodles, raw meat from supermarkets, ice cream from ice cream parlors, cooked food from delicatessens or food stalls, or beverages like "coffee to go". They are also commonly used to serve takeout food from restaurants, and are also available by request for diners who wish to take home the remainder of their meal. The foam is a good thermal insulator, making the container easy to carry as well as keeping the food at the temperature it had when filled into the container, whether hot or cold. Construction and composition Foam take-out containers are made from expanded polystyrene (EPS) foam, or another type of polystyrene foam, and produced by injecting the foam into a mold. They are usually white in color, although they may be printed or impressed with a company logo or other message. EPS foam is sometimes incorrectly called Styrofoam as a generic term. St ...

Expanded Polystyrene Foam
Polystyrene (PS) is a synthetic polymer made from monomers of the Aromatic hydrocarbon, aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to oxygen and water vapour and has a relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year. Polystyrene can be naturally Transparency (optics), transparent, but can be colored with colorants. Uses include protective packaging (such as Foam peanut, packing peanuts and in the Optical disc packaging#Jewel case, jewel cases used for storage of optical discs such as CDs and occasionally DVDs), containers, lids, bottles, trays, tumblers, disposable cutlery, in the making of models, and as an alternative material for phonograph records. As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room tempe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biodegrade
Biodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi. It is generally assumed to be a natural process, which differentiates it from composting. Composting is a human-driven process in which biodegradation occurs under a specific set of circumstances. The process of biodegradation is threefold: first an object undergoes biodeterioration, which is the mechanical weakening of its structure; then follows biofragmentation, which is the breakdown of materials by microorganisms; and finally assimilation, which is the incorporation of the old material into new cells. In practice, almost all chemical compounds and materials are subject to biodegradation, the key element being time. Things like vegetables may degrade within days, while glass and some plastics take many millennia to decompose. A standard for biodegradability used by the European Union is that greater than 90% of the original material must be converted into , water and minerals by ...

Cantonese Cuisine
Cantonese or Guangdong cuisine, also known as Yue cuisine ( or ) is the cuisine of Guangdong province of China, particularly the provincial capital Guangzhou, and the surrounding regions in the Pearl River Delta including Hong Kong and Macau.Hsiung, Deh-Ta. Simonds, Nina. Lowe, Jason. 005(2005). The food of China: a journey for food lovers. Bay Books. . p17. Strictly speaking, Cantonese cuisine is the cuisine of Guangzhou or of Cantonese speakers, but it often includes the cooking styles of all the speakers of Yue Chinese languages in Guangdong. Scholars categorize Guangdong cuisine into three major groups based on the region's dialect: Cantonese, Hakka and Chaozhou cuisines. The Teochew cuisine and Hakka cuisine of Guangdong are considered their own styles, as is neighboring Guangxi's cuisine despite eastern Guangxi being considered culturally Cantonese due to the presence of ethnic Zhuang influences in the rest of the province. Cantonese cuisine is one of the Eight Cu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hong Kong Cuisine
Hong Kong cuisine is mainly influenced by Cantonese cuisine, European cuisines (especially British cuisine) and non-Cantonese Chinese cuisines (especially Hakka, Teochew, Hokkien and Shanghainese), as well as Japanese, Korean and Southeast Asian cuisines, due to Hong Kong's past as a British colony and a long history of being an international port of commerce. Complex combinations and international gourmet expertise have given Hong Kong the labels of "Gourmet Paradise" and "World's Fair of Food".Sterling, Richard. Chong, Elizabeth. Qin, Lushan Charles 001(2001). ''World Food Hong Kong''. Hong Kong: Lonely Planet Publishing. . Background Modern Hong Kong has a predominantly service-based economy, and restaurant businesses serve as a main economic contributor. With the fourth-densest population per square metre in the world and serving a population of 7 million, Hong Kong is host to a restaurant industry with intense competition. Due to its small geographical size, Hong Kong c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Chinese Cuisine
American Chinese cuisine is a cuisine derived from Chinese cuisine that was developed by Chinese Americans. The dishes served in many North American Chinese restaurants are adapted to American tastes and often differ significantly from those found in China. History Chinese immigrants arrived in the United States seeking employment as miners and railroad workers. As larger groups arrived, laws were put in place preventing them from owning land. They mostly lived together in ghettos, individually referred to as "Chinatown". Here the immigrants started their own small businesses, including restaurants and laundry services. By the 19th century, the Chinese community in San Francisco operated sophisticated and sometimes luxurious restaurants patronized mainly by Chinese. The restaurants in smaller towns (mostly owned by Chinese immigrants) served food based on what their customers requested, anything ranging from pork chop sandwiches and apple pie, to beans and eggs.

Canadian Chinese Cuisine
Canadian Chinese cuisine (french: Cuisine chinoise canadienne) is a popular style of Canadian cooking original to take-out and dine-in eateries found across Canada. It was the first form of commercially available Chinese food in Canada. This cooking style was invented by early Cantonese immigrants who adapted traditional Chinese recipes to Western tastes and the available ingredients. This cuisine developed in a similar process to American Chinese cuisine. History Chinese workers were employed in the 1800s by Chinese labour contractors during the construction of the Canadian Pacific Railway linking Montreal, Quebec, with Vancouver, British Columbia. Many of those workers who stayed once the railway was completed resorted to opening small inexpensive restaurants or working as cooks in mining and logging camps, canneries, and in the private homes of the upper classes in cities and towns. They prepared variations on traditional Cantonese food that were well received by local pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methanogen
Methanogens are microorganisms that produce methane as a metabolic byproduct in hypoxic conditions. They are prokaryotic and belong to the domain Archaea. All known methanogens are members of the archaeal phylum Euryarchaeota. Methanogens are common in wetlands, where they are responsible for marsh gas, and in the digestive tracts of animals such as ruminants and many humans, where they are responsible for the methane content of belching in ruminants and flatulence in humans. In marine sediments, the biological production of methane, also termed methanogenesis, is generally confined to where sulfates are depleted, below the top layers. Moreover, methanogenic archaea populations play an indispensable role in anaerobic wastewater treatments. Others are extremophiles, found in environments such as hot springs and submarine hydrothermal vents as well as in the "solid" rock of Earth's crust, kilometers below the surface. Physical description Methanogens are coccoid (spherical shap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Styrene
Styrene () is an organic compound with the chemical formula C6H5CH=CH2. This derivative of benzene is a colorless oily liquid, although aged samples can appear yellowish. The compound evaporates easily and has a sweet smell, although high concentrations have a less pleasant odor. Styrene is the precursor to polystyrene and several copolymers. Approximately 25 million tonnes of styrene were produced in 2010, increasing to around 35 million tonnes by 2018. Natural occurrence Styrene is named after storax balsam (often commercially sold as ''styrax''), the resin of Liquidambar trees of the Altingiaceae plant family. Styrene occurs naturally in small quantities in some plants and foods (cinnamon, coffee beans, balsam tree (other), balsam trees and peanuts) and is also found in coal tar. History In 1839, the German apothecary Eduard Simon isolated a volatile liquid from the resin (called ''storax'' or ''styrax'' (Latin)) of the Liquidambar styraciflua, American sweetgu ...

Chinese Cuisine
Chinese cuisine encompasses the numerous cuisines originating from China, as well as overseas cuisines created by the Chinese diaspora. Because of the Chinese diaspora and historical power of the country, Chinese cuisine has influenced many other cuisines in Asia and beyond, with modifications made to cater to local palates. Chinese food staples such as rice, soy sauce, noodles, tea, chili oil, and tofu, and utensils such as chopsticks and the wok, can now be found worldwide. The preferences for seasoning and cooking techniques of Chinese provinces depend on differences in historical background and ethnic groups. Geographic features including mountains, rivers, forests, and deserts also have a strong effect on the local available ingredients, considering that the climate of China varies from tropical in the south to subarctic in the northeast. Imperial royal and noble preference also plays a role in the change of Chinese cuisine. Because of imperial expansion and trading, i ...
