Each batch of oats that comes into Australia is accompanied by certification documents. However, GK Gluten Free Foods sends samples to Symbio in Brisbane, which is an independent testing facility. We test each batch for gluten contamination so that each batch is uncontaminated. The gluten from Symbio is reported as <3ppm as this is the level of quantification for their testing. They use the R-biopharma test kit for gluten, which uses an antigen-antibody reaction to determine gluten levels.  <3ppm effectively equates to ‘0’ or nil gluten detected. Updates to the labelling law in 2015 now allow us to label this product “Low Gluten”. Low Gluten simply means <20ppm which still doesn’t represent the purity of our product.
