Since the higher temperatures can degrade preservatives and potentiate other chemical routines, testing AET at the upper temperatures could be assessing the worst scenario circumstance. Accelerated testing is often finished in the course of progress, and with enough information and facts, AET testing of economic once-a-year steadiness batches might not be needed. Through progress, it is useful to conduct AET over a “foundation” components minus preservative, flavours, fragrance or advancement-limiting here things at their least expensive concentrations. The pH should really ideally be the envisioned vary closest to that favouring advancement. Usage of organisms outside of that essential via the compendia is also prompt through this testing stage.
