Abstract
Solutions of sugars obtained during the processing of foodstuffs can be subject to bacterial contamination. In view of the possible legislation to prevent the use of existing disinfectants such as formaldehyde in these conditions, alternative treatments are needed. Effective disinfection of sugar solutions can be achieved employing a peracetic acid solution containing a high mole ratio of hydrogen peroxide to peracetic acid, such as from 18:1 to about 54:1 in combination with a second peracetic acid solution.
