[0002] Fruit and vegetable juice beverages are drinks made from fresh or refrigerated fruits and vegetables, extracted using physical methods such as pressing and soaking, and then blended with water, sugar, acids, and other ingredients. They are divided into two main categories: fruit juice beverages (fruit juice content ≥10%) and vegetable juice beverages (vegetable juice content ≥5%). Only products containing 100% fruit or vegetable juice can be called fruit and vegetable juice; others must be labeled as fruit and vegetable juice beverages. The production process includes raw material processing, crushing, juicing, and sterilization. Homogenization and degassing technologies are used to improve stability.
