Download Electron Beam Pasteurization and Complementary Food by Suresh Pillai, Shima Shayanfar PDF

By Suresh Pillai, Shima Shayanfar

Nutrition safeguard is a continuing problem for the nutrients undefined, and nutrition irradiation expertise has constructed considerably considering that its advent, relocating from isotope irradiation to using electron beam know-how. Electron Beam Pasteurization and Complementary foodstuff Processing Technologies explores the appliance of electron beam pasteurization at the side of different nutrition processing applied sciences to enhance the security and caliber of nutrients. half one offers an outline of the problems surrounding electron beam pasteurization in nutrition processing. half seems at diverse thermal and non-thermal meals processing applied sciences that supplement irradiation. ultimately, a case learn part at the advertisement functions of e-beam processing offers examples from undefined.

The spot size of the electron beam is a fundamental parameter because it determines the minimum dose capability of the eBeam system and the dose uniformity that can be achieved for low doses. 1 Continued Key Fraction Ratio % Physical units –50 –30 Uniformity –10 10 Distance (cm) Fraction of maximum dose Maximum dose Width 30 50 IDmax Dmax Figure 3 from reference [1] modified for clarity. The scan uniformity comes from the definition of scan width. 9 Dmax) value. 1 or 10%. 01 0 Measure a scan profile with dosimeters and determine the maximum dose value.

GAO concluded, “Pathogens such as Salmonella and E. coli O157:H7 continue to cause severe foodborne illness outbreaks, with the populations most susceptible to these illnesses growing in number. 999 percent” (GAO, 2010). Irradiation is typically used as the final intervention step applied in a company’s multi-hurdle Hazard Analysis Critical Control Point (HACCP) and Hazard Analysis and Risk-based Preventative Controls (HARPC) system in accordance with regulatory approvals and under regulatory inspection.

The energy limits for electrons and X-rays are: • Electron irradiation: – The maximum electron energy that can be used to directly treat food products is 10 MeV in every country where food irradiation is allowed. – Any energy up to 10 MeV may be used. 5 MeV. – The maximum electron energy that can be used to produce X-rays in all other countries for food irradiation is 5 MeV. – The X-ray converter (aka target) must be constructed of a material that does not produce neutrons. 5 MeV: tantalum, gold Key issues in setting the right dose are: • Minimum required dose (to achieve the DESIRED effect(s)) • Maximum allowed dose (to avoid any UNDESIRED effects) • The ratio between the maximum allowed dose and the minimum required dose is called the ALLOWABLE DUR • The DUR in the product must be less than the maximum allowable DUR or the product will not be properly treated.
