Homogeneity Testing
Digipath Labs can also test for homogeneous distribution of cannabinoids in infused edible products. Homogeneity testing determines if the cannabinoid potency of infused edible products is evenly distributed throughout the product. This is done to ensure that cannabinoid concentration is not too high or too low in any area of the product.
Homogeneity testing is conducted either by analyzing replicates of a single serving size or by dividing a given edible product, e.g., a cookie, into 5 or 6 equal pieces. Each serving size or piece is then extracted individually and analyzed independently for the cannabinoid profile and content. Comparing the cannabinoid results across the smaller pieces that make up the edible is of great interest to the producer to either confirm that their blending protocol is adequate or to alert them that further attention is needed to uniformly incorporate cannabis extract into the final product.
