Large Scale Fixed Bed Ion-Exchange System for Removing Strontium-90 from Fluid Milk. II. Compositional Studies
1967
Abstract Nine runs of 45,400 liters of milk per 8-hr day have been made, resulting in an average of 91.7% removal of environmental levels of Sr 90 . No significant increase in microbial population occurred during the runs, and the keeping quality of the processed milk appeared to be satisfactory. Flavor scores averaged 37.2 after processing, a decrease of 0.6 from the untreated samples. Minor compositional changes were found in freezing point, curd tension, titratable acidity, and ash. There was an increase of 0.36% in concentration of potassium citrate, due to acidification and neutralization of the milk. The remaining components tested showed insignificant changes.
