The work aims to review the effect and application of four commonly used coating materials in the storage and preservation of mango. By comparing the four most commonly used coating materials in mango preservation, such as chitosan (CTS), konjac glucomannan (KGM), sodium alginate (SA) and carboxymethyl cellulose (CMC), the preservation effects of single material coating and composite coating on mango were clarified, and the existing problems and development prospects in this field were also summarized. At present, the research on fresh keeping coating of mango mainly focused on the use of non-toxic coating materials combined with other preservation methods for storage experiments. The research ideas and methods were mature, but there was no united standard for preservation coating materials, and the preservation mechanism needed to be further studied. The coating preservation technology for mango has a good development prospect, and the development of a new composite coating with green, safe and edible properties is the future development direction.
