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

Food production and processing of quality food and safe food are today of primary importance. Food production is based on the principles of Good Agricultural Practice (GAP), Good Manufactoring Practice (GMP) and Good Hygiene Practice (GHP). Recently, the industrial food processing is focused dominantly on the quality, and one of the basic requirements of the quality is the safety. There are different methods and techniques to produce safe food. The up-to-date food technologies and quality measurements (quality control and quality assurance) involve the application of different physical methods, e.g., high pressure, pulsing electrical field, nondestructive techniques, e.g., nuclear magnetic resonance (NMR), near infrared reflectance, near infrared transmittance (NIR-NIT), photo acoustic spectroscopy (PAS) and instrumental neutron activation analysis (INAA) for chemical composition determination, radiation techniques, nanofiltration and reverse osmosis (RO) as well. Using ionizing radiation (nuclear methods) and non-ionizing radiation technologies, it is possible to fulfill a lot of expectations: decrease of microbial contamination, improve of sensory properties, increase of storability, etc..展开更多
