An important factor influencing a substance's volatility is the strength of the interactions between its molecules. Attractive forces between molecules are what holds materials together, and materials with stronger intermolecular forces , such as most solids, are typically not very volatile.
The CARB revised the definition of "Volatile Organic Compounds" used in their consumer products regulations, based on the committee's findings. [ 18 ] In addition to drinking water , VOCs are regulated in pollutant discharges to surface waters (both directly and via sewage treatment plants) [ 19 ] as hazardous waste, [ 20 ] but not in non ...
Volatile acid concentration can be used to detect adulteration of butter with less expensive fats. Butterfat has uncommonly high levels of volatile butyric and caproic acids, and mixing with fats from other sources dilutes the volatile acids. A measurement of the volatile acids is known as the Reichert Meissel value. [19] [20] [21]
Food safety (or food hygiene) is used as a scientific method/discipline describing handling, preparation, and storage of food in ways that prevent foodborne illness.The occurrence of two or more cases of a similar illness resulting from the ingestion of a common food is known as a food-borne disease outbreak. [1]
Some plant volatiles can be smelled by humans and give plants like basil, eucalyptus, and pine their distinctive odors. [1] The mixture and ratios of individual volatiles emitted by a plant under given circumstances (also referred to as synomones in the context of natural enemy attraction) is referred to as a volatile profile. These are highly ...
A food contaminant is a harmful chemical or microorganism present in food, which can cause illness to the consumer. Contaminated food The impact of chemical contaminants on consumer health and well-being is often apparent only after many years of processing and prolonged exposure at low levels (e.g., cancer ).
The onslaught of food recalls — listeria in 12 million pounds of meat, E. coli in McDonald’s Quarter Pounders, and many others — has been hard to ignore lately, raising the question: Are ...
Maize plants emit volatiles to attract the parasitic wasps Cotesia marginiventris and Microplitis rufiventris to attack African cotton leafworm. [12] [13] In some species GLVs enhance the attraction of sex pheromones. [4] [14] For example, green leaf volatiles have been found to increase the response of tobacco budworm to sex pheromone. Budworm ...
