Sunset Yellow FCF
Sunset yellow FCF (also known as orange yellow S, or C.I. 15985) is a petroleum-derived orange azo dye with a pH-dependent maximum absorption at about 480 nm at pH 1 and 443 nm at pH 13, with a shoulder at 500 nm. When added to foods sold in the United States, it is known as FD&C Yellow 6; when sold in Europe, it is denoted by E Number E110. Uses Sunset yellow is used in foods, cosmetics, and drugs. Sunset yellow FCF is used as an orange or yellow-orange dye. For example, it is used in candy, desserts, snacks, sauces, and preserved fruits. Sunset yellow is often used in conjunction with E123, amaranth, to produce a brown colouring in both chocolates and caramel. Safety The acceptable daily intake (ADI) is 0–4 mg/kg under both EU and WHO/FAO guidelines. Sunset yellow FCF has no carcinogenicity, genotoxicity, or developmental toxicity in the amounts at which it is used. It has been claimed since the late 1970s, under the advocacy of Benjamin Feingold, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petroleum
Petroleum, also known as crude oil or simply oil, is a naturally occurring, yellowish-black liquid chemical mixture found in geological formations, consisting mainly of hydrocarbons. The term ''petroleum'' refers both to naturally occurring unprocessed crude oil, as well as to petroleum products that consist of refining, refined crude oil. Petroleum is a fossil fuel formed over millions of years from anaerobic decay of organic materials from buried prehistoric life, prehistoric organisms, particularly planktons and algae, and 70% of the world's oil deposits were formed during the Mesozoic. Conventional reserves of petroleum are primarily recovered by oil drilling, drilling, which is done after a study of the relevant structural geology, sedimentary basin analysis, analysis of the sedimentary basin, and reservoir characterization, characterization of the petroleum reservoir. There are also unconventional (oil & gas) reservoir, unconventional reserves such as oil sands and oil sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Azo Dyes
Azo dyes are organic compounds bearing the functional group R−N=N−R′, in which R and R′ are usually aryl and substituted aryl groups. They are a commercially important family of azo compounds, i.e. compounds containing the C−N=N−C linkage. Azo dyes are synthetic dyes and do not occur naturally. Most azo dyes contain only one azo group but there are some that contain two or three azo groups, called "diazo dyes" and "triazo dyes" respectively. Azo dyes comprise 60–70% of all dyes used in food industry, food and textile industry, textile industries. Azo dyes are widely used to treat textile, textiles, leather, leather articles, and some foods. Chemically related derivatives of azo dyes include #Azo pigments, azo pigments, which are insoluble in water and other solvents. Classes Many kinds of azo dyes are known, and several classification systems exist. Some classes include disperse dyes, metal-complex dyes, reactive dyes, and substantive dyes. Also called direct d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Food Colorings
Food coloring, color additive or colorant is any dye, pigment, or substance that imparts color when it is added to food or beverages. Colorants can be supplied as liquids, powders, gels, or Paste (food), pastes. Food coloring is commonly used in commercial products and in domestic cooking. Food colorants are also used in various non-food applications, including cosmetics, pharmaceuticals, home craft projects, and medical devices. Some colorings may be natural, such as with carotenoids and anthocyanins extracted from plants or cochineal from insects, or may be synthesized, such as tartrazine yellow. In the manufacturing of foods, beverages and cosmetics, the food safety, safety of colorants is under constant scientific review and certification by national Regulatory agency, regulatory agencies, such as the European Food Safety Authority (EFSA) and US Food and Drug Administration (FDA), and by international reviewers, such as the Joint FAO/WHO Expert Committee on Food Additives. ...

PH Indicators
A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be determined visually or spectroscopically by changes in absorption and/or emission properties. Hence, a pH indicator is a chemical detector for hydronium ions (H3O+) or hydrogen ions (H+) in the Arrhenius model. Normally, the indicator causes the color of the solution to change depending on the pH. Indicators can also show change in other physical properties; for example, olfactory indicators show change in their odor. The pH value of a neutral solution is 7.0 at 25°C ( standard laboratory conditions). Solutions with a pH value below 7.0 are considered acidic and solutions with pH value above 7.0 are basic. Since most naturally occurring organic compounds are weak electrolytes, such as carboxylic acids and amines, pH indicators find many applications in biology and analytical chemistry. Moreover, pH indicators form one of the three main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tartrazine is a synthetic lemon yellow azo dye primarily used as a food coloring. It is also known as E number E102, C.I. 19140, FD&C Yellow 5, Yellow 5 Lake, Acid Yellow 23, Food Yellow 4, and trisodium 1-(4-sulfonatophenyl)-4-(4-sulfonatophenylazo)-5-pyrazolone-3-carboxylate. Tartrazine is a commonly used coloring agent all over the world, mainly for yellow, and can also be used with brilliant blue FCF (FD&C Blue 1, E133) or green S (E142) to produce various green shades. It serves as a dye for wool and silks, a colorant in food, drugs and cosmetics and an adsorption-elution indicator for chloride estimations in biochemistry. History Tartrazine was discovered in 1884 by Swiss chemist Johann Heinrich Ziegler, who developed the yellow azo dye in the laboratories of the Bindschedler'sche Fabrik für chemische Industrie in Basel ( CIBA). This was patented and produced in Germany by BASF in 1885 (DRP 34294). The process was first presented in 1887 in '' Chemische Bericht ...

Center For Science In The Public Interest
The Center for Science in the Public Interest (CSPI) is a Washington, D.C.–based non-profit watchdog and consumer advocacy group. History and funding CSPI is a consumer advocacy organization. Its focus is nutrition and health, food safety, and alcohol policy. CSPI was founded in 1971 by the microbiologist Michael F. Jacobson, along with the meteorologist James Sullivan and the chemist Albert Fritsch, two fellow scientists from Ralph Nader's Center for the Study of Responsive Law. In the early days, CSPI focused on various aspects such as nutrition, environmental issues, and nuclear energy. However, after the 1977 departure of Fritsch and Sullivan, CSPI began to focus largely on nutrition and food safety and began publishing nutritional analyses and critiques. CSPI has 501(c)(3) status. Its chief source of income is its ''Nutrition Action Healthletter'', which has about 900,000 subscribers and does not accept advertising. The organization receives about 5 to 10 percent of ...
