Problems solved by technology

[0002] At present, most of the dried fruits sold in the market are soaked in sugar, and some are dried after peeling and removing seeds. In order to prevent insects or mildew in dried fruits, they must be soaked in sulfur before drying, or smoked or soaked. , if it is not treated in this way, the shelf life will be very short. If it is treated, the sulfur content in the dried fruit will exceed the standard, which is not good for the health of consumers. Moreover, more and more people like to eat low-sugar dried fruit from now on. I don't like dried fruit with high sugar content, so developing a low-sugar and sulfur-free dried fruit with a long shelf life is an important topic for scientific and technological workers.
