The purpose of this study was to explore the drying kinetics, effective moisture diffusivity, activation energy, color variation, and the thermal degradation properties of anthocyanins of blood-flesh peach under hot air drying for the first time. The results showed that the hot air-drying process of blood-flesh peach belongs to reduced-speed drying. The Page model could accurately predict the change of moisture ratio of blood-flesh peach. The effective moisture diffusivity during hot air drying of blood-flesh peach was in the range between 1.62 × 10−10 and 2.84 × 10−10 m2/s, and the activation energy was 25.90 kJ/mol. Fresh samples had the highest content (44.61 ± 4.76 mg/100 g) of total monomeric anthocyanins, and it decreased with the increase of drying temperature. Cyanidin-3-O-glucoside and delphinidin-3-O-galactoside were the main anthocyanins of blood-flesh peach as identified and quantified by UPLC-QqQ-MS. Interestingly, during the drying process, the content of cyanidin-3-O-glucoside increased at the beginning, and then decreased. However, the content of delphinidin-3-O-galactoside kept decreasing during the whole drying process. Considering the drying efficiency, fruit color and quality, 70 °C would be a suitable temperature for drying blood-flesh peach. This research will provide beneficial information for understanding the anthocyanin degradation of blood-flesh peach during drying, and guide the production of high-quality dried products.

The "One Belt, One Road" concept was born as a new type of regional cooperation structure to promote the multi-faceted and coordinated development of countries along the route. Dunhuang assumes an important historical role in promoting the "One Belt, One Road" construction. Dunhuang culture is an important part of the "One Belt, One Road" concept. This paper analyses Dunhuang culture in a number of dimensions to further collate the historical role it has played and could play in the "One Belt, One Road" process. The construction of "One Belt, One Road" is a dynamic process. This paper aims to explore and utilise Dunhuang culture to enrich the connotation of "One Belt, One Road" and promote its construction.
