Abstract:n this paper, the TRIZ evolutionary trees was introduced into the field of food, the existing patents of pomelo peel related products were analyzed, and the evolutionary trees of pomelo peel related products was constructed, so as to predict the future development direction of pomelo peel products. Through the construction of pomelo peel product evolution trees, four development directions of pomelo peel products in the future can be found: (1) To develop pomelo peel products in gaseous form; (2) For the branches of evolutionary trees with many nodes, new products can be obtained by deleting or replacing the elements in the original system through system extension-clipping route and system component clipping route. (3) For the branches of the evolutionary trees with fewer nodes, new products can be obtained by introducing some new substances and fields, or by deleting or replacing the elements in the original system. (4) Different types of products are designed for the characteristics of different functional components.
