Effect of different modes of transport on logistics quality of broccoli

摘要: 以新鲜西兰花为试材,研究了不同运输方式对西兰花物流品质和物流寿命的影响。定期测定西兰花黄化率、腐烂率、呼吸强度、叶绿素含量等品质指标。结果表明:西兰花常温运输极易黄化,物流寿命仅1 d;加冰运输和冷藏运输能显著降低黄化率、呼吸强度,延缓叶绿素和抗坏血酸(VC)含量下降,使西兰花物流寿命延长至3 d;在黄化控制上加冰运输和冷藏运输效果相近,但在腐烂控制上加冰运输不及冷藏运输。冷藏运输是西兰花最好的运输方式,但在没有冷藏运输条件下,加冰运输为西兰花的长途运输和销售提供了另一种可能。Abstract: Taking fresh broccoli as materials,effect of different modes of transport on logistic quality and logistic life of broccoli was studied. The yellowing rate,decay rate,respiratory intensity,chlorophyll content,and other quality indicators were investigated regularly.The results showed that the broccoli was very prone to yellowing at ambient temperature,the effective circulation life of broccoli was only 1d.Ice transport and low temperature transport could reduce significantly yellowing rate,respiration intensity,delay the decrease of chlorophyll content and VCcontent,the effective circulation life of broccoli was prolonged to 3d. In the control of yellowing,effect of ice transport was similar to low temperature transport,but in the control of decay,effect of ice transport was lower than low temperature transport. Low temperature transport was the best transportation mode,but in the absence of refrigerated transport conditions,ice transport provided another possible for long- distance transport and sale of broccoli.
