If you understand the product is inherently hostile because of pH, drinking water action or preservative; and there's a very low bioburdon at release, repeated testing will unlikely demonstrate any microbial adjustments.
Carry out the adverse Management through the use of 1 list of tube / Petri plates of 90ml of sterile society media.

Given that the higher temperatures can degrade preservatives and potentiate other chemical pursuits, testing AET at the upper temperatures could well be analyzing the worst case scenario. Accelerated testing is typically completed through enhancement, and with sufficient information, AET testing of economic once-a-year security batches will not be vital. All through enhancement, it is useful to accomplish AET with a “foundation” components minus preservative, flavours, fragrance or advancement-limiting components at their least expensive degrees. The pH really should Preferably be the anticipated variety closest to that favouring development. Use of organisms beyond that demanded because of the compendia is likewise proposed for the duration of this testing stage.
