Abstract:Using Physalis alkekengi L. as the main material and based on single factor and orthogonal experiments, the best production conditions of preserved Physalis were optimized as sugar concentration of 50%, sugar-dipping time of 24 h, drying temperature of 60 ℃ and drying time of 12 h. The effects of color-protecting, blanching, hardening, sugar-dipping and drying on the process technology of preserved Physalis were studied. The results showed that color-protecting, blanching and hardening were necessary. Sugar-dipping and drying were the most important processes, by which the sugar content and the quality of products were affected.
