防腐紫胶涂料,对某些果菜涂料处理后,在一定程度上起到延长供应期,提高经济收益的效果,因而这种处理已成为近代果菜经营中的重要技术措施之一。美国、日本及其它经济较发达的国家所生产的柑桔,除用于加工外,全部在上市前进行涂料处理。一、什么叫紫胶涂料在水果的表面涂上一层极薄的蜡、油、天然树脂或其它人造物料等,作为一种附加涂层,以减少水分蒸发、延缓后熟、抑制微生物的感染侵害,从而达到保水保鲜、减少腐烂和延长贮藏期的目的,有些涂料还能增加表面光 Corrosion-resistant shellac coatings, some of the fruit and vegetable paint processing, to a certain extent, play to extend the supply period, improve economic returns, and thus this treatment has become an important modern management of fruits and vegetables in one of the technical measures. Citrus fruits produced in the United States, Japan and other economically advanced countries, except for processing, are all disposed of before being marketed. First, what is a shellac coating on the surface of the fruit coated with a thin layer of wax, oil, natural resin or other man-made materials, as an additional coating to reduce evaporation of water, delay ripening, inhibition of microbial infection So as to achieve the purpose of keeping fresh water, reducing decay and prolonging the storage period. Some coatings can also increase the surface light
