摘要本研究旨在探讨城市生鲜市场供应链中运输、储存和零售货架条件对生菜品质和植物营养素损失的影响。减少采后损失是减少膳食植物营养素损失和改善消费者健康的优先事项。南非关于城市新鲜农产品市场供应链中收获后和营养损失的信息有限。在这项研究中，我们量化了采后损失，植物化学物质的变化，以及生菜中矿物质在Tshwane新鲜农产品市场供应链不同点的损失。本研究包括来自两个不同省份（豪登和西北部）的Tshwane新鲜农产品市场的蔬菜供应，以供比较。来自这两个省的生菜是从五个不同的农场收集的。鲜重损失、视觉质量变化、植物营养素特性和莴苣在供应链点的经济损失：（a）运输;（B）储存;（c）和零售货架。从豪登省和西北省的每个供应链点随机选择五箱生菜。结果表明，零售货架上的高温（25°C）和低相对湿度（40%）会影响生菜的重量、整体品质和植物营养素特性。由于生菜质量低劣，零售货架上的累积经济损失较高。该研究确定了在营销过程中发生的主要质量和植物营养素损失。该研究表明，在营销过程中，主要的食物和营养损失发生在哪里。这一信息将通过引入管理粮食和营养损失的技术，大大有利于粮食可持续性。
Abstract This study was initiated to investigate the impact of transportation, storage, and retail shelf conditions on lettuce quality and phytonutrients losses in the urban fresh produce market supply chain. Reducing postharvest losses is a priority to reduce the loss of the dietary‐based phytonutrients and to improve the health of the consumers. Limited information is available in South Africa related to the postharvest and nutrition loss in the urban fresh produce market supply chain. In this study, we quantified the postharvest losses, changes in phytochemicals, and loss of minerals in lettuce at different points of Tshwane Fresh Produce Market supply chain. Lettuce supply to the Tshwane Fresh Produce Market from two different provinces, Gauteng and North West, were included in this study for comparison. Lettuce from the two provinces was collected from five different farms. The loss of fresh weight, changes in visual quality, phytonutrition properties, and economic loss of lettuce at the supply chain points: (a) transport; (b) storage; (c) and at the retail shelf was investigated. Five boxes of lettuce per supply chain point from Gauteng and North West provinces were randomly selected. The results indicated that the high temperature (25°C) and low RH (40%) at the retail shelf affected the weight, overall quality, and phytonutrition properties of lettuce. Cumulative economic loss was higher at the retail shelf due to the inferior quality of lettuce. The study identified where major quality and phytonutrition losses occur during marketing. The study demonstrated to identify the where major food and nutritional loss losses occur during marketing. This information will significantly benefit food sustainability by introducing technologies to manage food and nutrition losses.
