摘　　要：西兰花不但含有多种维生素、矿物质和膳食纤维等成分,同时还含有酚类、黄酮等抗氧化活性物质,是一种营养丰富、有保健作用的蔬菜。鲜切西兰花因其方便、安全的特性而受到消费者的青睐,但是鲜切西兰花在加工过程中会产生营养成分流失、易受微生物的侵染等问题,加速变质、衰老进程引起品质劣变。因此,如何有效维持鲜切西兰花的品质和延长其货架期是鲜切西兰花加工技术的关键。该文综述了目前国内外有关鲜切西兰花保鲜技术,主要包括物理保鲜技术(减压、微波、包装、臭氧和UV-C等)和化学保鲜技术(乙醇、杀菌剂和1-MCP等)以及生物保鲜技术(中草药提取液、可食性涂膜和精油)。综合比较各项保鲜技术对鲜切西兰花的保鲜效果,发现物理和生物结合的保鲜技术具有广阔的研究潜力,以期为今后鲜切西兰花保鲜研究提供参考。Broccoli not only contains a variety of vitamins, minerals, dietary fiber and other ingredients, but also contains phenols, flavonoids and other antioxidative substances. Fresh-cut broccoli has increasingly favored by consumers for its nutrition, healthiness, convenience and safety. However, fresh-cut broccoli is easy to be infected by microorganisms, which results the loss of nutrients and deterioration and senescence of broccoli. Therefore, understanding how to effectively maintain the quality of fresh-cut broccoli and extend its shelf life are crucial. This paper systematically introduced techniques that have been used for preserving fresh-cut broccoli, including physical (decompression, microwave, packaging, ozone, and UV-C etc.), chemical (ethanol, fungicides, and1-MCP etc.), and biological (Chinese herbal extracts, edible film, and essential oil) preservation techniques. After comparing various preservation techniques comprehensively, it was found that combined physical and biological fresh-keeping techniques has broad research potential, which provides a reference for future research on fresh-cut broccoli preservation.
