We are a food flavouring manufacturer. Currently we have 3 products which are liquid flavours, powder flavours and emulsion.
We are setting up a new microbe lab and would like to check our products for microbe. However, we can't find any microbial standard for food flavouring.
FYI, the solvent we use for liquid flavours are ethanol, propylene glycol, palm oil and triacetin. The percentage of the solvent is about 70-99%. According to research journal, PG itself is an antimicrobial so I think for liquid flavouring, the risk for microbe is very low.
But for powder and emulsion flavours, it contains starch. So we are now looking for microbial standard for our food flavouring. Any recommendation ?
Thank you so much.
