Application of ozone in grain processing

Production of Medicated Bedding Straw: Challenges and Perspectives

“…Even though some of the previously discussed disinfectants are efficient, alternative environmental friendly treatments should also be considered. Ozonation is a well-established method of disinfecting water whether it is for drinking supplies, bottled water, swimming pools or wastewater treatment plants (Guzel-Seydim et al, 2004;Tiwari et al, 2010). Ozone disinfection is a green alternative to chemical disinfection.…”

“…Ozone disinfection is a green alternative to chemical disinfection. Its capacity to react with numerous chemical groups, offers many advantages, such as wide antimicrobial spectrum which combined with a high oxidation potential makes it an attractive processing option for the food industry (Tiwari et al, 2010). Ozone decomposes quickly, and leaves no residues while fruits and vegetables treated with ozone were found to have a considerably longer shelf-life (Guzel-Seydim et al, 2004;Tiwari et al, 2010).…”

Inactivation of E. coli and B. subtilis spores in ozonized cassava starch

“…Among these technologies, ozone stands out for its antimicrobial properties and for being totally degradable in oxygen with no waste/toxic products (TIWARI et al, 2008(TIWARI et al, , 2010; thus it is generally recognized as safe (GRAS) for food applications (GUZEL-SEYDIM;GREENE;SEYDIM, 2004;DHILLON et al, 2009;TIWARI et al, 2010). An additional advantage is the lower cost of ozone equipment (GUZEL-SEYDIM;GREENE;SEYDIM, 2004).…”

“…The ozone is a high oxidative compound with a broad antimicrobial spectrum; it is able to inactivate bacterial vegetative cells and spores, yeast, molds, and viruses and to kill insects in stored grains and degrade mycotoxins (TIWARI et al, 2010). Ozone inactivates microorganisms by the progressive oxidation of vital cellular components.…”

“…In general, Gram negative bacteria are more sensitive to ozone treatment than Gram positive ones (KHADRE; YOUSEF; KIM, 2001). However, several other factors affect the ozone efficacy including the strain of the microorganism, age of the culture, density of the treated population, and presence of ozone-demanding medium components and method of applying ozone (KHADRE; YOUSEF; KIM, 2001) In spores, ozone degrades the coat layer components thus exposing the cortex and the core to oxidation by ozone TIWARI et al, 2010). The molecular ozone and the reactive by-products of ozone decomposition (free radicals: OH -, O 2 and HO 3 -) have antimicrobial activity.…”
