Vegetable powders offer a convenient way to incorporate various nutrients into your diet. Common vegetable powders like spinach, carrot, beetroot, and tomato powder are typically dehydrated and ground into a fine powder. They are often rich in vitamins, minerals, and antioxidants. Key specifications for these powders include color, aroma, flavor, particle size, moisture content, and microbial load. The powders should be free from contaminants, additives, and excessive moisture. Additionally, they should retain their nutritional value and have a long shelf life when stored properly in airtight containers in a cool, dry place.
