“…Measurements were recorded using the CIELab system (L*, a*, and b* coordinates). Total colour differences (∆E) throughout the shelf life were compared to their respective initial values according to equations previously described by Torres-Sánchez et al [27]. A texturometer (Brookfield, CT3-4500, Toronto, ON, Canada) was used to test firmness at room temperature (RT) with a cylinder of 8 mm diameter and a surface area of 2.01 cm 2 and compressing the fruit by 5 mm at a contact speed of 2 mm s −1 , expressing these results in newtons (N).…”

Background: Our objective was to evaluate carotenoid accumulation in bell peppers during shelf life under different light conditions. Methods: Fruit stored for 6 d at 7 °C received a 9 kJ m−2 UV-B treatment, while non-UV-treated were used as control (CTRL). Subsequently, all peppers were disposed for a retail sale period of 4 d at 20 °C with a photoperiod of 14 h under fluorescent light (FL) + 10 h under darkness (D), FL, or blue + red LEDs (BR LED). Results: Total antioxidant capacity (TAC) was increased by the UV-B treatment and the photoperiods supplemented with FL and BR LED, which was directly related to the carotenoid content. In fact, CTRL peppers (225 mg β-carotene kg−1) under FL+BR LED showed an increase of ~33% of 13-cis-β-carotene, ~24% of all-trans-β-carotene, and ~27.5% of 9-cis-β-carotene compared to FL + D and FL + FL. Capsaicinoids showed an increase by ~22%, ~38%, and ~27% in the content of capsanthin, capsanthin laurate, and capsanthin esters, respectively, after the UV-B treatment, which was even enhanced after the LED-supplemented photoperiod by ~18% compared to FL+D. Conclusions: Illumination with BR LEDs + UV-B during the retail sale period nights is recommended to increase the bioactive content of bell peppers via carotenoid accumulation to 270 mg β-carotene kg−1.

“…Additionally, (Feng et al , 2019) used a WSN network to monitor several quality factors dynamically such as temperature, humidity, O 2 and CO 2 to improve the safety of frozen shellfish during CSC. Finally, Torres-Sánchez et al (2020) proposed a real-time monitoring system using multiple non-linear regression to predict the shelf life of fruits and vegetables based on temperature, relative humidity and gas concentration.…”

PurposeCold supply chain (CSC) distribution systems are vital in preserving the integrity and freshness of transported temperature sensitive products. CSC is also known to be energy intensive with a significant emission footprint. As a result, CSC requires strict monitoring and control management system during storage and transportation to improve safety and reduce profit losses. In this research, a systematic review of recent literature related to the distribution of food CSC products is presented and possible areas to extend research in modeling and decision-making are identified.Design/methodology/approachThe paper analyzes the content of 65 recent articles related to CSC and perishable foods. Several relevant keywords were used in the initial search, which generated a list of 214 articles. The articles were screened based on content relevance in terms of food vehicle routing modeling and quality. Selected articles were categorized and analyzed based on cost elements, modeling framework and solution approach. Finally, recommendations for future research are suggested.FindingsThe review identified several research gaps in CSC logistics literature, where more focused research is warranted. First, the review suggests that dynamic vehicle modeling and routing while considering products quality and environmental impacts is still an open area for research. Second, there is no consensus among researchers in terms of quality degradation models used to assess the freshness of transported cold food. As a result, an investigation of critical parameters and quality modeling is warranted. Third, and due to the problem complexity, there is a need for developing heuristics and metaheuristics to solve such models. Finally, there is a need for extending the single product single compartment CSC to multi-compartment multi-temperature routing modeling.Originality/valueThe article identified possible areas to extend research in CSC distribution modeling and decision-making. Modified models that reflect real applications will help practitioners, food authorities and researchers make timely and more accurate decisions that will reduce food waste and improve the freshness of transported food.

“…The determination and monitoring of quality properties of fresh produce are often forgotten or missed in traditional supply chain management. However, non-destructive methods have been developed over the last decade and have shown potential for application during storage and supply chain [7][8][9][10]. Simultaneously, information and communication technology (ICT) and the Internet of Things (IoT) in various aspects of agribusiness have been studied and reported, especially in developed countries [11][12][13].…”

Karo Highlands in North Sumatra, Indonesia, provides for a significant portion of horticultural products for domestic and overseas markets. Carrot suffers up to 50% postharvest loss throughout the supply chain. Poor supply chain management and lack of quality monitoring limits competitiveness and aggravates postharvest loss. Non-destructive techniques integrated with Internet-of-Things (IoT) is essential in the modern food supply chain. Implementing these technologies needs to be strategic to achieve benefits without increasing the supply chain’s burden. The study aims to identify the carrot supply chain's situation, design the IoT-based mechanism for traceability and quality monitoring based on the critical points where the postharvest loss occurs in the supply chain, and determine and calculate influential variables formulation of the proposed mechanism regarding resources limitations. The study designs a business process for the IoT architecture implementation and utilizes Goal Programming to evaluate and optimize the performance of the IoT architecture into the supply chain. The implementation design involves farmers, suppliers, and exporting firms to operate the measurement and monitoring devices and accessible information for stakeholders. A minimum set of IoT devices was determined for a particular minimum product flow and required minimum information flow to achieve the optimum postharvest loss reduction.
