摘要

摘要本研究研究了在南非典型商业条件下,消毒处理和储存条件对收获和运输的番茄营养品质特性的影响。试验处理包括在两个季节、三个成熟期、三种运输条件(不同距离和路面)、四种消毒处理(对照、热水、氯化或阳极水结合生物防治)和两种储存条件(低温(11°C)和环境)下收获西红柿。对于冬季收获的果实,与其他处理相比,热水处理(夏季收获也是如此)或酸液+生物防治和冷藏处理的抗坏血酸(AA)浓度最高。在较短且相对平坦的道路上运输的果实,其AA(夏收成)和番茄红素浓度高于在中等粗糙路面上运输距离最远的果实。收获季节和消毒处理对糖的浓度有显著影响。供应链中番茄的营养特性不仅受到环境和采后实践的影响,还受到道路质量的影响,这在本研究中是第一次得到证实。建议将西红柿冷藏,用热水或阳极水消毒+生物防治,以及制定运输计划,以尽量减少使用粗糙的路面,并使用最短的距离到市场,作为该行业的最佳做法。应研究改进水果包装的方法,以提供足够的缓冲,防止运输过程中的物理损坏。

Nutrient quality characteristics of fresh tomatoes subjected to various transportation and disinfection treatments under commercial conditions in South African supply chains
ABSTRACT This study investigated effects of disinfection treatments and storage conditions on the nutrient quality characteristics of tomatoes harvested and transported under typical commercial conditions in South Africa. The experimental treatments included harvest of tomatoes in two seasons, three maturity stages, three transportation conditions (varying distances and road surface profiles), four disinfection treatments (control, hot water, chlorinated or anolyte water in combination with biocontrol) and two storage conditions (cold (11°C) and ambient). For fruit harvested in winter, treatment with hot water (also for summer harvest) or with anolyte water + biocontrol and storage in cold conditions resulted in the highest concentrations of ascorbic acid (AA) compared with the other treatments. Fruit transported along the shorter and relatively smoother roads maintained higher AA (summer harvest) and lycopene concentrations compared with fruit transported the longest distance with moderately rough surface profile. The harvesting season and the disinfection treatments had significant effects on the concentrations of sugars. The nutrient characteristics of the tomatoes in the supply chain were shown to be affected not only by environmental and postharvest practices, but also by the road quality, demonstrated for the first time in this study. Cold storage of tomatoes, disinfection with hot water or anolyte water + biocontrol, and transportation planning to minimise the use of rough road surfaces and to use the shortest distances to markets, were recommended as best practices for the industry. Options for improvement of fruit packaging to provide adequate cushioning against physical damage during transportation should be investigated.

期刊介绍: Biological Agriculture & Horticulture aims to act as the central focus for a wide range of studies into alternative systems of husbandry, and particularly the biological or organic approach to food production. The Journal publishes work of a sound scientific or economic nature related to any aspect of biological husbandry in agriculture, horticulture and forestry in both temperate and tropical conditions, including energy and water utilization, and environmental impact.
