Preparing Seeds and Handling Oil
How can I verify the quality and purity of my oil?
Direct Answer
Use traceable raw materials, production records and tests appropriate to the oil and intended market. Color, smell, a burn test or the machine's name cannot prove purity and safety on their own.
Detailed Engineering Analysis
Agree a testing plan with a competent laboratory. Depending on the product, it may cover identity or adulteration, acid value, peroxide value, moisture and relevant contaminants. Keep representative retained samples and link each result to its batch. Cold pressing does not remove the need to control raw-material hazards. Use actual test evidence when describing your product, and avoid claims that the oil prevents or cures diseases without appropriate substantiation.
