Microbiological Testing

Another analysis that must be done on every batch is microbiological testing. If your L-theanine is approved for ID, assay, heavy metals, and residual solvents, but is contaminated with bacteria, then you could be putting your customers at risk. This is where microbiological testing comes into play. You must ensure that every single batch of raw material and finished good being sold to consumers does not contain harmful microbiological contaminants. At Omnient Labs, we use a couple different methodologies like water activity and ATP testing to ensure a sample is not contaminated and cannot grow microbiological contaminants. If any material is outside of those specs, full microbiological culture testing is done to elucidate exactly which contaminants are there.
