菠萝皮薄汁多,营养丰富,属鲜嫩易腐性水果,采收、运输和销售过程极易造成机械损伤。在西双版纳地区采收旺季正值高温多雨的6——8月,十分有利于病原菌滋生,对菠萝贮运不利。1986年我们受农牧渔业部农垦局委托承担了“无眼菠萝贮运保鲜技术的生产实验研究”课题。三年来在菠萝产地进行23次试验,供试菠萝共4,174千克,在常温下贮藏,研制出效果较好的复方植物多糖涂膜保鲜剂。其特点是能抑制采后菠萝以呼吸代谢为主的生理生化过程,推迟生理衰老,延长贮藏寿命,有利于长途运输;增强对潜伏病原 Pineapple thin juicy, nutrient-rich, is a fresh perishable fruit, harvesting, transportation and marketing process can easily cause mechanical damage. In the Xishuangbanna harvest season peaked at high temperature and rainy June - August, it is very conducive to the growth of pathogenic bacteria, pineapple storage and transportation adversely. In 1986, we were entrusted by the Reclamation Bureau of the Ministry of Agriculture, Animal Husbandry and Fisheries to undertake the “Experimental Production of Preserved Preserving Technology without Eyes Pineapple” project. Three years in the pineapple origin 23 tests for a total of 4,174 kg pineapple test, stored at room temperature, developed a better effect of compound plant polysaccharide coating preservative. Its characteristic is to inhibit post-harvest pineapple respiratory metabolism-based physiological and biochemical processes, postponed physiological aging, prolonging storage life, is conducive to long-distance transport; enhance the latent pathogens
