The present invention relates to a food structure and a manufacturing process thereof. A mixture of ingredients like sweet potato, tapioca starch, pitaya, sugar, etc. is mainly used as an outer layer wrap and a small amount of cranberry unit is used as stuffing. With the above structure, the manufacturing process comprises: cooking at least one sweet potato after being performed with surface treatment and making it into mashed sweet potatoes for later use； then taking at least one pitaya to perform surface treatment and making it into a pitaya juice； adding the mashed sweet potatoes and the pitaya juice with tapioca starch and sugar and kneading them into a mixture； taking at least one cranberry unit to be filled in the mixture to form at least a semi-finished product； and finally heating and cooking the semi-finished product to form a starch composition. Accordingly, natural ingredients such as pitaya and cranberry are used to form a novel food product having natural unique color, soft and hard multi-level mouthfeel, and sweet and sour taste stimuli.本發明為有關一種食品結構及其製程，主要以地瓜、樹薯粉、火龍果、糖等食材的混合物做為外層包裹，並以少許蔓越莓單元做為其內餡。藉上述結構，對至少一地瓜進行表面處理後，加以煮熟並製成地瓜泥備用，再取至少一火龍果進行表面處理後製成火龍果汁，接著將地瓜泥及火龍果汁添加樹薯粉及糖後，揉製成一混合物，並取至少一蔓越莓單元充填於混合物內，而形成至少一半成品，最後將半成品加熱熟成，而形成一澱粉組合物。藉此，利用火龍果及蔓越莓等天然食材，形成天然的特有色澤，配合軟硬不同的多層次口感，及酸酸甜甜的味覺刺激，而製成一種創新的食品。
