Contaminants like heavy metals (e.g., lead, mercury) and pesticides can be harmful when ingested. For example, high levels of lead in the extract can cause lead poisoning, especially if used in dietary supplements or medications.
• Product Stability: Purity also affects the stability of the product. Impurities may react with the active compounds or cause chemical changes during storage. For instance, some impurities may accelerate the oxidation of flavonoids in the extract, reducing its shelf - life.
• Quality and Reputation: In all industries, a pure extract powder is associated with high - quality products. Companies that can ensure the purity of their Glycyrrhiza root extract powder are more likely to gain a good reputation and customer trust.

3.3 Factors Affecting Purity

• Raw Material Source: The source of the Glycyrrhiza root is a significant factor. If the roots are grown in areas with high pesticide use or polluted soil, there is a greater risk of contamination. For example, roots from regions near industrial areas may be contaminated with heavy metals from factory emissions.
• Manufacturing Processes: During the extraction and purification processes, improper handling can introduce contaminants. For instance, if the extraction equipment is not properly cleaned, residues from previous extractions may contaminate the new batch of extract powder. Also, the use of low - quality solvents or purification agents can leave behind unwanted substances.
• Packaging and Storage: The packaging material and storage conditions can also affect purity. If the packaging is not airtight or moisture - proof, contaminants from the environment can enter the powder. For example, if stored near chemicals, there is a risk of the powder absorbing volatile substances, thus reducing its purity.

4. Implications on Product Performance

4.1 In Pharmaceuticals

• Efficacy: The potency and purity of Glycyrrhiza root extract powder are directly related to the efficacy of pharmaceutical products. A high - potency and pure extract can ensure that the intended pharmacological effects are achieved. For example, in anti - inflammatory medications, the proper potency of glycyrrhizic acid is necessary for effective reduction of inflammation, and purity ensures that there are no harmful side - effects due to contaminants.
• Dosage Accuracy: Purity is crucial for accurate dosage determination. Contaminants can affect the overall mass of the extract powder, making it difficult to accurately measure the required amount of active compounds. Inaccurate dosage can lead to either sub - optimal treatment or potential toxicity.
