摘要：The amount of losses caused by good (GHP) and poor (PHP) practices in the post-harvest processes of lettuce and tomato was determined under real supply chain conditions. Along with the commercial losses, changes in the nutritional and microbiological quality of crops were also quantified. The results showed that the weight loss of lettuce and tomato was reduced three and nine-fold, respectively by GHP during supply chains. The retail-display and transportation of the product in the postharvest process were determined to be the most critical supply chain stages affecting quality. The nutritional quality of crops exposed to PHP has shown differences by both crop and compound. The microbial quality of the produces, however, was adversely affected by the poor postharvest handling practices. In conclusion, still huge amounts of postharvest losses can be avoided if already known good postharvest handling practices are employed with a holistic perspective in produce supply chains.
