Considering that the upper temperatures can degrade preservatives and potentiate other chemical routines, testing AET at the upper temperatures could well be assessing the worst scenario state of affairs. Accelerated testing is often finished during growth, and with sufficient information and facts, AET testing of economic yearly stability batches may not be essential. For the duration of growth, it is useful to complete AET with a “foundation” method minus preservative, flavours, fragrance or development-limiting aspects at their lowest ranges. The pH must Preferably be the predicted selection closest to that favouring growth. Use of organisms outside of that essential via the compendia can be instructed through this testing stage.
