Method Description
Foreign organic matter refers to plant-based contaminants that are not part of the intended product composition, such as weed seeds, other plant parts, or organic debris. This analysis is particularly important for agricultural commodities and botanical ingredients where contamination can affect product purity, potency, and safety. Detection helps ensure that products meet quality specifications and regulatory standards for organic contaminants.
