Blood Tofu
Pig blood curd (), also known as "blood tofu" or "blood pudding" (), is a popular Cantonese delicacy in Hong Kong, southern China, Taiwan, and Vietnam. It is commonly served with carbohydrates, such as noodles or congee. Background Pig blood curd originated from blood rice pudding () in southern China. Blood rice pudding is a pastry made from blood and rice grains. Rice is the main ingredient of southern Chinese cuisine; the two common methods to cook rice are steaming and boiling. Duck meat is a source of supplement (), however, because of the poor living conditions in the past, poultry was only offered as sacrifices in Chinese festivals. In order to get nutrition from the ducks, farmers saved the blood, steamed it with rice, and served it with sauce. Later, blood rice pudding spread to neighboring towns and villages, and people named it duck blood pudding (). However, because of the rising price of duck, and the inability of chicken blood to coagulate into pudding, pig blood rep ...

Blood Curd
Many cultures consume blood, often in combination with meat. The blood may be in the form of blood sausage, as a thickener for sauces, a Curing (food preservation), cured salted form for times of food scarcity, or in a blood soup. This is a product from domesticated animals, obtained at a place and time where the blood can run into a container and be swiftly consumed or processed. In many cultures, the animal is slaughtered. In some cultures, blood is a taboo food and drink#Blood, taboo food. Blood is the most important byproduct of Animal slaughter, slaughtering. It consists predominantly of protein and water, and is sometimes called "liquid meat" because its composition is similar to that of lean meat. Blood collected hygienically can be used for human consumption, otherwise it is converted to blood meal. Special fractions of animal blood are used in human medicine. Methods of preparation Sausage Blood sausage is any sausage made by cooking animal blood with a filler until i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitamin C
Vitamin C (also known as ascorbic acid and ascorbate) is a water-soluble vitamin found in citrus and other fruits and vegetables, also sold as a dietary supplement and as a topical 'serum' ingredient to treat melasma (dark pigment spots) and wrinkles on the face. It is used to prevent and treat scurvy. Vitamin C is an essential nutrient involved in the repair of tissue, the formation of collagen, and the enzymatic production of certain neurotransmitters. It is required for the functioning of several enzymes and is important for immune system function. It also functions as an antioxidant. Most animals are able to synthesize their own vitamin C. However, apes (including humans) and monkeys (but not all primates), most bats, some rodents, and certain other animals must acquire it from dietary sources. There is some evidence that regular use of supplements may reduce the duration of the common cold, but it does not appear to prevent infection. It is unclear whether supple ...

Taiwanese Cuisine
Taiwanese cuisine (, Bopomofo:ㄊㄞˊㄨㄢˉㄌㄧㄠˋㄌㄧˇ, or , Bopomofo:ㄊㄞˊㄨㄢˉㄘㄞˋ) has several variations. The earliest known cuisines of Taiwan are that of the Taiwanese indigenous peoples. Over hundred years of historical development; mainstream Taiwanese cuisine has been influenced by Hakka cuisine, the cuisines of the '' waishengren,'' and Japanese cuisine. Although southern Fujian cuisine has had the most profound impact. History and development Taiwanese culinary history is murky and is intricately tied to patterns of migration and colonization. Local and international Taiwanese cuisine, including its history, is a politically contentious topic. Taiwan's complex and diverse identity makes Taiwanese cuisine hard to communicate. The history of Taiwanese cuisine began with the cuisine of aboriginal peoples on the island of Taiwan, which existed in the ancient times without written records. From the Ming dynasty in 16th century, a large number of im ... [...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. .

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 ...

Iron Poisoning
Iron poisoning typically occurs from ingestion of excess iron that results in acute toxicity. Mild symptoms which occur within hours include vomiting, diarrhea, abdominal pain, and drowsiness. In more severe cases, symptoms can include tachypnea, low blood pressure, seizures, or coma. If left untreated, iron poisoning can lead to multi-organ failure resulting in permanent organ damage or death. Iron is available over the counter as a single entity supplement in an iron salt form or in combination with vitamin supplements and is commonly used in the treatment of anemias. Overdoses on iron can be categorized as unintentional ingestion which is predominantly associated with children or intentional ingestion involving suicide attempts in adults. Unintentional ingestion of iron containing drug products are a major cause of mortality in children under the age of 6 years old in the United States. As a response, in 1997 the US Food and Drug Administration (FDA) implemented a regulation r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lecithin
Lecithin (, from the Greek ''lekithos'' "yolk") is a generic term to designate any group of yellow-brownish fatty substances occurring in animal and plant tissues which are amphiphilic – they attract both water and fatty substances (and so are both hydrophilic and lipophilic), and are used for smoothing food textures, emulsifying, homogenizing liquid mixtures, and repelling sticking materials. Lecithins are mixtures of glycerophospholipids including phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylserine, and phosphatidic acid. Lecithin was first isolated in 1845 by the French chemist and pharmacist Théodore Gobley. In 1850, he named the phosphatidylcholine ''lécithine''. Gobley originally isolated lecithin from egg yolk – λέκιθος ''(lekithos)'' is "egg yolk" in Ancient Greek – and established the complete chemical formula of phosphatidylcholine in 1874; in between, he demonstrated the presence of lecithin in a variety of biologi ...

Niacin (substance)
Niacin, also known as nicotinic acid, is an organic compound and a form of vitamin B3, an essential human nutrient. It can be manufactured by plants and animals from the amino acid tryptophan. Niacin is obtained in the diet from a variety of whole and processed foods, with highest contents in fortified packaged foods, meat, poultry, red fish such as tuna and salmon, lesser amounts in nuts, legumes and seeds. Niacin as a dietary supplement is used to treat pellagra, a disease caused by niacin deficiency. Signs and symptoms of pellagra include skin and mouth lesions, anemia, headaches, and tiredness. Many countries mandate its addition to wheat flour or other food grains, thereby reducing the risk of pellagra. The amide derivative nicotinamide (niacinamide) is a component of the coenzymes nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP+). Although niacin and nicotinamide are identical in their vitamin activity, nicotinamide doe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calcium
Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth's crust, and the third most abundant metal, after iron and aluminium. The most common calcium compound on Earth is calcium carbonate, found in limestone and the fossilised remnants of early sea life; gypsum, anhydrite, fluorite, and apatite are also sources of calcium. The name derives from Latin ''calx'' "lime", which was obtained from heating limestone. Some calcium compounds were known to the ancients, though their chemistry was unknown until the seventeenth century. Pure calcium was isolated in 1808 via electrolysis of its oxide by Humphry Davy, who named the element. Calcium compounds are widely used in many industries: in foods and pharma ...

Phosphorus
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). In minerals, phosphorus generally occurs as phosphate. Elemental phosphorus was first isolated as white phosphorus in 1669. White phosphorus emits a faint glow when exposed to oxygen – hence the name, taken from Greek mythology, meaning 'light-bearer' (Latin ), referring to the " Morning Star", the planet Venus. The term '' phosphorescence'', meaning glow after illumination, derives from this property of phosphorus, although the word has since been used for a different physical process that produces a glow. The glow of phosphorus is caused by oxidation of the white (but not red) phosphorus — a process now called chem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residue ...
