Ethene (common name ethylene) is a commercially important organic compound. Millions of tons of ethene are?

produced by the chemical industry each year. Ethene is used in the manfucature of synthetic fibers for carpeting and clothing, and it is widely used in making polyethylene. Low-density polyethylene can be streched into a clear, thin film that is used for wrapping food productss and consumer goods. High-density polyethylene is molded into bottles for milk and other liquids. Ethene can also be oxidized to produce ethylene glycol, which is used in antifreeze for automobiles.
At standard atmospheric pressure, the boiling point of ethylene glycol is 198degress C, compared to ethene that boils at -104degrees C.

The Produce Contamination Problem: Causes And Solutions $78.49 This book is organized into five sections beginning with an introduction in which the problem is described in terms of the number and size of produce related outbreaks the commodities involved and the human pathogens involved. The introduction also documents the failure of conventional sanitizing treatments to assure microbiological safety examining the problems of microbial attachment. The second section reviews methods of identifying a contamination source (epidemiology trace back strain identification location of Source) and then focuses on the various sources of microbial contamination (water manure airborne dust wildlife human activity) and where in the crop production sequence they might result in contamination. In the third section some of the commodities associated with major outbreaks (leafy vegetables tomatoes cantaloupes apples berries sprouts) are examined to determine what characteristics make them especially vulnerable to contamination. The fourth section then addresses means of avoiding produce contamination through use of Good Agricultural Practices and recommendations in FDA and industry guidance documents. Regulatory actions (recalls restrictions on imports) to safeguard the public from potentially hazardous products are described. Coverage includes policy and practices in the US Mexico and Central America Europe and Japan. The fifth section examines current technologies for reducing human pathogens in fresh produce including disinfection rapid methods for detecting contaminants irradiation gas-phase application and best practices acceptable to organic growers packers and processors. *Addresses foodborne contaminations from a prevention view providing pro-active solutions to the problems *Covers core sources of contamination and methodologies for identifying those sources *Includes best practice and regulatory information
