Detergents and wetting agents are widely used in the washing of fruits, tomatoes, and vegetables when these foods are prepared for canning, freezing, or fresh consumption. Although the use of detergents in food washing produces desirable results, the possibility exists that a residue problem may be created. Various raw foods, including green beans, brussels sprouts, asparagus, and tomatoes were used in experiments designed to demonstrate the sensitivity of radioisotopic tracer techniques for detecting and measuring detergent residue on washed foods. Results are tubulated. A comparison was made of colorimetric methods and radioisotopic methods for measuring the removal of alkyl benzene sulfonate from detergent-washed green beans. (C.H.)
