Abstract: A new-class composite of fruit wax/nano-SiOX was composed of wax coating agent made of natural plants and animals,nano-SiOX and other ingredients.It was a kind of water soluble oil liquid fruit wax,with three types of colour (brown,red and yellow)and a series of different concentrations of wax coating agents and nano-SiOX.The permeability of RY fruit wax was affected byboth concentrations of nano-SiOX and wax coating agent.The performances of nano-SiOX fruit wax on brightening fruit,improvingfruit glossy appearance and reducing fruit moisture loss could match the same type of imported fruit wax and its function ofprotecting against decay was superior to the same type of imported fruit wax.

Key words: fruit wax, freshness, nano-SiO_X
