“…The levels of K, P, and Ca in lettuce heads did not vary significantly between the transport and storage points ( (Table 7B). The loss of mineral elements at the retail shelf was also reported in leafy vegetables (Gogoa, Opiyob, Ulrichs, & Huyskens-Keila, 2017). The loss of mineral elements in this study was mainly due to the higher temperature at the retail shelf that had favored the metabolic changes and senescence (Gogoa et al, 2017).…”

“…The geographic site of production, distance from the Tshwane Fresh Produce Market, conditions during agricultural production, postharvest handling, and storage conditions at the farm could have played a vital role in determining the quality (Gogoa et al., ). It is evident in this study that economic losses associated with crisphead lettuce increased along the supply chain.…”

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.

“…Wrong demand forecasting results in either in food shortage or food surplus. In food surplus case, the extra products cannot be produced on time and turns into waste (Campbell and Munden-Dixon, 2018;Chauhan et al, 2018;Beausang et al, 2017;Canali et al, 2017;Gogo et al, 2017;Redlingshöfer et al, 2017;Priefer et al, 2016;Beretta et al, 2013). Producers can make wrong forecasting due to various reasons such as supply agreements with retail chains, government subsidiaries, and lack of information dissemination within the supply chain.…”

Food loss is one of the factors that lead to severe problems in food security, environment, global and regional and national economies around the world today. The issue of food loss reduction has recently achieved much public attention to combat global hunger and improve food security. There is a growing trend about determining food loss prevention and recovery programs all around the world. Similarly, the number of studies that focus on food loss issues has been increased but these studies mostly give attention to consumer/household stages. Thus, this paper aims to gather and synthesize all food loss drivers that are found in empirical studies. For this purpose, a systematic literature review was conducted. We examined articles from different journals, which are published between 2011 and 2018. Results of the systematic literature review revealed that four drivers cause food loss in the production stage; five drivers lead to food loss in the processing stage and five drivers are the reason for food loss in the distribution and retailing stage.

“…Since high-level practices can ensure the safety of packaged perishable food [55], current packaging mode can be effectively promoted in the low-level cold chain practice in developing countries [56] for further loss prevention. Thus, this methodology can be used to further exhibit the demonstrated advantage in cold chain, especially fresh green produces.…”

A Holistic Packaging Efficiency Evaluation Method for Loss Prevention in Fresh Vegetable Cold Chain

With the continuous push for improving packaging efficiency of current packaging practices to prevent losses in a real cold chain, a holistic evaluation method with improved indicators and a conceptual assessment framework to improve packaging efficiency continuously in a fresh vegetable cold chain was proposed. Based on two fresh leafy vegetables with typical packaging practices in a real cold chain in China, the evaluation method was performed and tested from a macro perspective, and then the packaging efficiency constitution with loss prevention perspective was better visualized. The results show that the method can be used for improving the performance of specific packaging efficiency in the fresh vegetable cold chain and improving the suggestions' sustainability orientation, and systematically summarize their impacts on packaging efficiency; specifically as follows: (1) Since the correlation between the state of fresh vegetables and the environmental stress in the package, the performance of the micro-environment parameters should be given priority for packaging efficiency improvement in loss prevention. (2) Although the use of the packaging materials in current practices was relatively better, it still can improve in food safety and packaging sustainability of the packaging practices through the selection of packaging materials with better sustainability characteristics. (3) Via the visualization of targeted packaging efficiency in cold chain, the fluctuation of loss rates in the cold chain process are well perceived, and there are still room can be performed continuously to realize more efficient packaging for better loss prevention. (4) The method has drawbacks that the optimization of the weights to the given indicators and the indicators based on nutrition and quality of fresh produce was not considered in current research, and it should be strengthened in future research. (5) It is necessary that the perception of differences in targeted packaging efficiency and the consciousness to improve specific packaging efficiency in vegetable cold chain for sustainability.Sustainability 2019, 11, 3874 2 of 18 and quality loss in the packaging [6,7] that the monitoring and controlling the process environment in vegetable cold chain can reduce losses. Losses during the cold chain contribute a lot to the losses of green produce in the cold chain. For example, losses in storage accounted for about 15-20% and in distribution about 5-10% for vegetable [3], which has an undesirable impact on the environment and resources [8], as well as social welfare in China. Increasing demand for fresh produce and the severity of food losses force us to turn to a safer and greener vegetable cold chain. Thus, responding to these issues in cold chain practices, packaging, and ongoing improvement in loss prevention [9] is imperative.Efficient packaging practices are the crux for preservation and processes management, including storage and distribution, which effectively reduce the loss and securing safety of fresh vegetables [10] in co...
