A test showing “absence of development” during security storage wouldn't essentially rule out expansion probable. Progress opportunity can be far better established utilizing the AET the place organisms are literally added into the products, or by h2o activity (Aw) measurements in non-aqueous formulas, or a combination of each tests.

Since the higher temperatures can degrade preservatives and potentiate other chemical actions, testing AET at the upper temperatures would be assessing the worst circumstance situation. Accelerated testing is usually carried out all here through advancement, and with enough info, AET testing of business once-a-year balance batches will not be vital. In the course of progress, it is useful to carry out AET over a “foundation” formula minus preservative, flavours, fragrance or development-limiting variables at their least expensive ranges. The pH really should Preferably be the expected variety closest to that favouring progress. Utilization of organisms outside of that required through the compendia is likewise prompt during this testing phase.
