Consumer Behavior: Building Marketing Strategy

Tomato production can serve as a source of income for most rural and periurban producers in most developing countries of the world. However, postharvest losses make its production unprofitable in these parts of the world. Postharvest losses in tomatoes can be as high as 42% globally. Postharvest losses in tomatoes can be either quantitative or qualitative. Even though emphasis in crop research nowadays is increasing shifting from quantity to quality of produce, there is still little improvement in the quality of commercially produced tomato varieties, hence resulting in high quality losses. From the study it was discovered that the postharvest quality status of tomatoes partly depended on some preharvest practices carried out during production. Some of these factors are fertiliser application, pruning, maturity stage, cultivar selection, and irrigation. Using best postharvest handling practices or factors such as temperature, relative humidity, gases in storage, postharvest calcium chloride application, and physical handling procedures to maintain the quality after harvest was also critical. It was concluded by this study that understanding and managing both preharvest and postharvest factors properly will reduce the postharvest quality losses in tomatoes.

Preharvest and Postharvest Factors Affecting the Quality and Shelf Life of Harvested Tomatoes: A Mini Review

Tomato production has increased in recent years due to the economic and nutritional importance of the crop. This increase is made possible by the numerous research advances made along the entire value chain. However, scientific research has been focussed mainly on production whilst neglecting postharvest issues. Tomato producers have therefore enjoyed good harvests in recent times, though the good harvests of those from developing countries do not translate into profit as most are lost after harvest. From this study, it was revealed that the postharvest quality and shelf life of the fruit in part will depend on some postharvest handling practices and treatments carried out after harvest. Handling practices like harvesting, precooling, cleaning and disinfecting, sorting and grading, packaging, storing, and transportation played an important role in maintaining quality and extending shelf life. Using appropriate postharvest treatments like refrigeration, heat treatment, modified atmosphere packaging (MAP), and 1-methylcyclopropene (1-MCP) and calcium chloride (CaCl2) application was also vital. It was concluded by this study that the quality of the harvested fruit can be maintained and shelf life extended by using appropriate postharvest handling practices and treatment methods. Failure to adhere to these practices will result in a high amount of loss.

Postharvest Handling Practices and Treatment Methods for Tomato Handlers in Developing Countries: A Mini Review

Removal of pesticide residues from fresh produce is important to reduce pesticide exposure to humans. This study investigated the effectiveness of commercial and homemade washing agents in the removal of surface and internalized pesticide residues from apples. Surface-enhanced Raman scattering (SERS) mapping and liquid chromatography tandem mass spectrometry (LC–MS/MS) methods were used to determine the effectiveness of different washing agents in removing pesticide residues. Surface pesticide residues were most effectively removed by sodium bicarbonate (baking soda, NaHCO3) solution when compared to either tap water or Clorox bleach. Using a 10 mg/mL NaHCO3 washing solution, it took 12 and 15 min to completely remove thiabendazole or phosmet surface residues, respectively, following a 24 h exposure to these pesticides, which were applied at a concentration of 125 ng/cm2. LC–MS/MS results showed, however, that 20% of applied thiabendazole and 4.4% of applied phosmet had penetrated into the apples followin...

Effectiveness of Commercial and Homemade Washing Agents in Removing Pesticide Residues on and in Apples

Fruits and vegetables are highly nutritious agricultural produce with tremendous human health benefits. They are also highly perishable and as such are easily susceptible to spoilage, leading to a reduction in quality attributes and induced food loss. Cold chain technologies have over the years been employed to reduce the quality loss of fruits and vegetables from farm to fork. However, a high amount of losses (≈50%) still occur during the packaging, pre-cooling, transportation, and storage of these fresh agricultural produce. This study highlights the current state-of-the-art of various advanced tools employed to reducing the quality loss of fruits and vegetables during the packaging, storage, and transportation cold chain operations, including the application of imaging technology, spectroscopy, multi-sensors, electronic nose, radio frequency identification, printed sensors, acoustic impulse response, and mathematical models. It is shown that computer vision, hyperspectral imaging, multispectral imaging, spectroscopy, X-ray imaging, and mathematical models are well established in monitoring and optimizing process parameters that affect food quality attributes during cold chain operations. We also identified the Internet of Things (IoT) and virtual representation models of a particular fresh produce (digital twins) as emerging technologies that can help monitor and control the uncharted quality evolution during its postharvest life. These advances can help diagnose and take measures against potential problems affecting the quality of fresh produce in the supply chains. Plausible future pathways to further develop these emerging technologies and help in the significant reduction of food losses in the supply chain of fresh produce are discussed. Future research should be directed towards integrating IoT and digital twins for multiple shipments in order to intensify real-time monitoring of the cold chain environmental conditions, and the eventual optimization of the postharvest supply chains. This study gives promising insight towards the use of advanced technologies in reducing losses in the postharvest supply chain of fruits and vegetables.

Recent Advances in Reducing Food Losses in the Supply Chain of Fresh Agricultural Produce

Tomato ( Solanum lycopersicum L. ) is an important crop cultivated and consumed worldwide.  It provides a wide variety of nutrients and many health-related benefits to the human body. Tomato production can improve the livelihoods of small-scale producers by creating jobs and serving as source of income for both rural and peri-urban dwellers. Despite all these benefits, many constraints make tomatoes production unprofitable in Africa. Post-harvest looses is one of such constraints. Post-harvest losses have been found to be either an on-farm or off-farm problem. On-farm losses are caused by improper harvesting stages, excessive field heat, improper harvesting containers, poor farm sanitation and improper packaging materials. Causes of off-farm losses includes lack of access roads, inappropriate transportation system, lack of processing factories and lack of reliable market information. Using low-cost intermediate technology intervention can help reduce some of these post-harvest losses making tomato production a more profitable venture in Africa. Keywords : Post-harvest, Losses, Tomatoes.

An Overview of Post-Harvest Losses in Tomato Production in Africa: Causes and Possible Prevention Strategies

The source of conflict between Supermarkets and Wet-markets arise from the use of market power and economies of scale by one group against the other. This study explores the tensions that exist between modern retailers and their traditional counterparts as a result of the influx of supermarkets in Ghana. The main objective of the study is to compare attributes related to the control of access to consumers by the Supermarket and the Wet-market. In this study, the dot-survey approach of Rapid Market Assessment Technique was used to elicit information from 438 respondents at the Madina market (wet-market) and Melcom (supermarket) over a period of two weeks and Wilcoxon-Mann-Whitney (WMW) comparison test and descriptive statistics were employed for the analysis. The results revealed that consumers patronise the supermarkets for convenience and the wet-market for freshness of product. Their purchasing decisions were affected by their level of education and product selections of the retailer. The highly educated preferred to shop at the Supermarket instead of the Wet-market; however, over 50% of respondents preferred the wet-market for fresh food products and the supermarket for non-food items. Each retailer receives its fair share of purchases from its loyal customers, therefore the revolution arising from the supermarket influx in Ghana has not yet resulted into conflict between supermarkets and their traditional counterparts, though it is inevitable if nothing is done to prevent it from happening. To avoid the conflict, it is recommended that policies should be instituted to (i) improve the market infrastructures and shopping environment in the Wet-markets, (ii) give tax concession to modern retailers who source products from local farmers and small-scale processors, (iii) enable traditional retailers position themselves on the fringe and co-exist with modern retailers and (iv) enforce public standards with regards to food safety laws in the traditional markets.

Conflict between Supermarkets and Wet-Markets in Ghana: Early Warning Signals and Preventive Policy Recommendations

Using gas chromatography—electron capture detector protocol, pesticide residue levels on four common vegetables (cabbage, carrot, lettuce, and tomatoes) consumed in Ho Municipal, Ghana, were investigated. A total of 5 kg each of the vegetables were randomly sampled in triplicate and from three different markets. Organochlorine pesticides, including residues of γ-HCH, δ-HCH, heptachlor, aldrin, p, p’-DDT, o, p’-DDT and p, p’-DDE detected in vegetables sampled were above recommended EU MRL. Lettuce recorded the highest aldrin (1.23 mg/kg) as well as γ-HCH (0.013 mg/kg) residue levels, while heptachlor (1.05 mg/kg) and δ-HCH (0.23 mg/kg) were highest for cabbage. Maximal residues of p, p’-DDT (1.194 mg/kg) and p, p’-DDE (0.147 mg/kg) were found in tomatoes. Though consumption of these vegetables does not currently pose significant health risk to both adults and children, consumers should be careful as residues could accumulate and pose chronic health hazards. Hence, there is a need for constant surveillance to regulate pesticide use in vegetable farming.
