A new process involving blanching in 0.05M citric acid and addition of 200 ppm CaNa2EDTA in the canning brine (ABC) was compared to the standard commercial method (SCM) for control of spoilage of canned mushrooms inoculated with C. sporogenes PA3679 spores. Fresh mushrooms were uniformly inoculated by vacuum hydration in spore suspensions. Compared to the SCM, the ABC process reduced the potential number of nonsterile units per million cans at Fo 10 from 14.8 to 2.1. At Fo 8 and 10, the ABC process reduced spoilage of the canned products from 100 to 68.1% and 89.3 to 28.7%, respectively, compared to the SCM.
