Apple and apple products are one kind of popular fruit and fruit products among the world. The planting acreage, output and trade quantity of the apples in the world are keeping increasing. At present, China has become the biggest apple producing and trading country. However, Chinese companies of concentrated apple juice suffer a serious deficit since the global financial crisis. The most important reasons are the rising cost of raw materials, less utilization and the single products. In order to solve these problems, pressing pre-peeled apple and the whole apple utilization were proposed, which not only solved the less processing quality, discoloration, pesticide residues and other issues, but also processed apples based on the nutrients of different parts (juice, flesh, peel and seeds). It may extend juice processing chain and achieve zero waste of processing apples which will be the future direction of the juice industry.
