When pasteurization is not an option to eliminate the microbiological load of a product, due to temperature sensitivity, filtration steps are routinely employed.
Even though filtration through 0,22 µm filters is an effective procedure, significant product loss can be expected.
Prior to this case study, the producer consistently measured a microbiological load below their guideline levels of 104 CFU/g before the last filtration rendering it redundant.
Due to the redundancy of the filtration product was lost with no real impact on the quality of the formulated product.
