3-MCPD (3-monochloropropane-1,2-diol or 3-chloropropane-1,2-diol) is an organic chemical compound with the formula HOCH 2 CH(OH)CH 2 Cl. It is a colorless liquid. The compound has attracted notoreity as the most common member of chemical food contaminants known as chloropropanols. [1] It is suspected to be carcinogenic in humans. [2]
MCPD was jointly developed by the International Board for Plant Genetic Resources (now Bioversity International) and the FAO. The Multi-Crop Passport Descriptor is intended to provide a standardised method of describing and exchanging information about plant genetic resources .
The linkages in a food web illustrate the feeding pathways, such as where heterotrophs obtain organic matter by feeding on autotrophs and other heterotrophs. The food web is a simplified illustration of the various methods of feeding that link an ecosystem into a unified system of exchange.
While many food contaminants have been known for decades, the formation and presence of certain chemicals in foods has been discovered relatively recently. These are the so-called emerging food contaminants like acrylamide, furan, benzene, perchlorate, perfluorooctanoic acid , 3-monochloropropane-1,3-diol (3-MCPD), 4-hydroxynonenal, and (4-HNE).
2-MCPD (2-chloropropane-1,3-diol) is an organic chemical compound with the formula ClCH(CH 2 (OH)) 2. It is a colorless liquid. The compound has attracted notoreity as a food contaminant. Together with the 3-MCPD, it is one of two chloropropanols food contaminants. [1] It is suspected to be carcinogenic in humans. [2]
An example of a topological food web (image courtesy of USDA) [1] The soil food web is the community of organisms living all or part of their lives in the soil. It describes a complex living system in the soil and how it interacts with the environment, plants, and animals. Food webs describe the transfer of energy between species in an ecosystem.
The FDA’s recent ban on Red Dye No. 3, set to take effect by 2027 for foods and 2028 for drugs, marks a significant step in addressing safety concerns over artificial food dyes in the U.S. food ...
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
