高脂膜是一种高级脂肪醇成膜物。成膜物的水乳液是一种非离子型的表面活性剂,其分子具有不对称的结构,一端含有极性的亲水基团,另一端是非极性的疏水基团。当高脂膜经稀释后,通过喷雾或洗果的方式附着于果实表面时,即形成一层很薄的、肉眼不可见的、连续的膜。其膜的分子间具有一定孔隙,允许二氧化碳和氧气缓慢通过,比无膜状态通过量明显减少。同时,此膜还能够部分阻止 High-fat film is a high fatty alcohol film. The film-forming aqueous emulsion is a non-ionic surfactant whose molecules have an asymmetric structure with polar hydrophilic groups on one end and non-polar hydrophobic groups on the other. When the high-fat film is diluted, it is attached to the surface of the fruit by spraying or washing fruit to form a thin, invisible, continuous film. The membrane has some pores between the molecules, allowing the slow passage of carbon dioxide and oxygen, than the state without a significant decrease in membrane throughput. At the same time, this film can also partially stop
