When evaluating Avocado Powder, the primary focus should be on the processing method, as it directly impacts nutrient retention. Freeze-dried (FD) powder is the gold standard for preserving healthy fats and vitamins, whereas spray-dried (SD) powder is more cost-effective but often requires carriers like maltodextrin. Buyers must verify the fat content (typically 40-60% for pure powder), moisture levels (<5%), and particle size (mesh count) to ensure it meets their specific application needs, whether for food, cosmetics, or supplements.
