Problems solved by technology

Among them, physical fresh-keeping technology consumes a lot of energy and has high cost, which limits its application.
The use of chemical preservatives (such as deoxyacetic acid, sulfur dioxide, sorbic acid, benlaite, etc.) to preserve fruit can achieve better results, but long-term use of many chemical preservatives will produce drug resistance, and at the same time have a certain impact on human health. Adverse effects, even carcinogenic, teratogenic, etc.
