摘　　要：研究冰温条件下不同厚度保鲜膜包装的西兰花品质变化情况,为西兰花的长期保鲜提供依据。结果表明,冰温库的温度控制性能良好,在(-0.1±0.2)℃之间波动;保鲜膜结合冰温贮藏对西兰花具有保鲜效果,保鲜膜越厚,保鲜效果越明显,能够有效延长西兰花贮藏时间,可达110d,比普通冷库有效延长贮藏期30d,同时能够防止西兰花霉烂,保持Vc和可溶性固形物含量,抑制色素降解。Under the condition of ice-temperature, the quality of broccoli packaged by different thickness of plastic film was test, which would provide the basis for long-term preservation of broccoli. The results showed that the ice-temperature storage had a stable temperature at -0.1 ℃ and the fluctuations is 0.2℃ . The ice-temperature storage combined with plastic-film package played a significant role in preservation of broccoli, the plastic film is thicker, the effect of preservation is more obvious, which can effectively extend the storage time of broccoli, up to 110 d, that is 30 d longer than the normal cold storage, meanwhile prevented broccoli to rot, maintained the Vc and soluble solids content, inhibited anthocyanin degraded.
