The role of food safety has developed significantly in the last 2 decades, so today the production and processing of safe and quality food is of primary importance. Modem food production is based on principles of GAP and GMP （including GHP） and different methods and tools for quality control and assurance （IFS, HACCP, ISO-9000, ISO-9000/2010, ISO-22000, TQM）. There are different techniques and methods to produce safe food and to control the quality of the foodstuffs. The modem, up-to-date technologies and measurement techniques involve the application of many physical methods - high pressure, pulsing electrical field, microwave, non-destructive techniques （e.g., INAA, NMR, NIR-NIT, PAS）, radiation treatments as well. Using radiation technologies （of course not only nuclear ones） it is possible to fulfil some very important expectations of modem food processing, e.g., decrease of microbial contamination, improvement of sensory properties, increase of storability of food products.展开更多

Eliminating hazards in systems and decreasing risks are their essential purposes with help of hazard identification, risk evaluation and management. By pre-control on major hazards, fatal accidents are avoided, stuffs＇ safety and healthy are protected, levels of safe management are enhanced, and perpetual systems are built up finally. However, choosing the proper identification and evaluation is a problem all along. Based on specific condition in Jiangou Coal Mine, method of LEC was applied for hazard identification and evaluation in the pre-blasting process within horizontal section top-coal mechanized caving of steep seams.

So, it is practical and operable for the method to develop the given scientific research and has a distinctive impact on high efficiency and safety products for pre-blasting in horizontal section top-coal mechanized caving of steep seams.展开更多
