These studies on persimmon jam have less consideration for the complementarity of the properties and characteristics of the raw materials. While retaining the nutrition of the raw materials, the process is more complicated, the production cost is high, or the long-term cooking makes the browning of the jam serious, which affects the sensory quality.
