Abstract
Cleaning and disinfection (c&d) in dairy processing is important for the hygienic status. Due to financial reasons the development of c&d goes to fully automated systems (CIP) without disassembling the equipment and with multiple application of the same c&d-solvent (re-use, total recovery). Active chlorine containing c&d-solvents can be used in all steps of dairy processing. The possibility of the contamination of the milk and dairy products with chloroform during CIP was investigated using an experimental CIP pilot plant. The analysis of chloroform was performed with headspace gaschromatography and electron capture detector (HS-GC with ECD). The concentration of active chlorine varied between 50 and 250 mg/l in the ready to use c&d solvent. The effect of pre and post rinsing on soil accumulation, active chlorine reduction, chloroform formation and chloroform transfer to raw milk was investigated. Chloroform contaminated raw milk was separated into cream resp. the cream phase converted into butter and chloroform accumulated in the fat rich products.
