Through improvement, it is helpful to conduct AET on a “foundation” components minus preservative, flavours, fragrance or expansion-limiting variables at their lowest amounts. The pH must ideally be the predicted vary closest to that favouring expansion. Utilization of organisms over and above that expected via the compendia can be proposed through this testing phase.
