纳米SiO_x保鲜果蜡研制

利用动、植物源蜡质作为果蜡的成膜剂,研制出棕、黄、红三种类型和浓度任意调配的水溶性油状液体果蜡。成膜剂浓度、纳米SiOX浓度均可影响RY蜡的透气性,纳米SiOx对RY保鲜蜡透气性的降低效应大于成膜剂。纳米SiOX保鲜果蜡在增加果品色泽、亮度及降低果品干耗等性能方面与进口果蜡相近,在防腐性能方面优于进口果蜡。

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.
