The Soil Association Certification Limited is UK’s largest organic certification body, campaigning for healthy, humane and sustainable food, farming and land use. Its organic certification is widely regarded as the GOLD standard for all organic products and is very difficult to achieve.
Certified organic products contain ingredients which come from plants and other natural products, such as minerals. To make sure that a product works, some natural ingredients need to be changed. Some of these changes are simple physical processes, such as chopping, blending or combining – ingredients which have undergone these types of processes are known as Physically Processed Agro-Ingredients (PPAI).
Other ingredients undergo chemical changes, for example, heating or boiling, oxidation (adding oxygen) or other chemical reactions. These are known as Chemically Processed Agro-Ingredients. The physical and chemical processes which are permitted by The Soil Association are carefully scrutinised to make sure that only the most sustainable types are allowed, in line with the principle of Green Chemistry.
