ABSTRACT A rapid, sensitive monitoring technique for the detection of microbial contamination of ascptic tomato paste systems has been developed. Samples are aseptically collected by means of a newly developed sampling technique and placed with media in incubation for variable time intervals and are analyzed for the presence of diacetyl or acetylmethyl‐carbinol by means of colorimetric assay or GLC. The technique can detect microbial spoilage in 4–12 hr compared to 72–96 hr using traditional methods. The technique also makes possible the ability to monitor bulk storage tanks automatically by sampling headspace gases above the product and injecting into a GLC.
