Reducing post-harvest losses through engineering innovation

Introduction

Because of the ever-increasing population all over the world, there is a considerable gap between the quantity of food that is available and the amount that is required. This gap is growing at an alarming rate. It is anticipated that by the year 2050, the size of the human population would have expanded from 7 billion to 9.7 billion, with the majority of this expansion taking place in countries that are not yet deemed to be developed [1] . In order to accommodate this growth, it is required to boost the productivity of food production by seventy percent. It is possible to accomplish this goal by either increasing the crop productivity or reducing the quantity of trash that is generated [2] . There are measurable quantities of food that are lost throughout the postharvest process, and these losses may be broken down into two categories: quantity and quality. The term "postharvest losses" (PHL) is used to describe these kinds of losses. A determined effort is being made to reduce these losses to the fullest degree that is practically possible under the circumstances [3] . Among the many actions that make up PHL, harvesting is one of the activities that are included. This category includes later acts such as consumption, availability, access, and usage of the product or service [4] . The study of PHL has the potential to enhance food security by providing sustainable ways that may increase food production while simultaneously reducing food losses and waste. This might be accomplished via several means. Several different approaches might be used to reach this goal [5] . PHL reduction is often more cost-effective than expanding food production, and it has the potential to yield bigger returns than improvements in agricultural production rates because of its ability to create larger returns.

Moreover, there is the possibility of a rise in agricultural output rates [6] . One of the goals that the United Nations has established as part of the Sustainable Development Goals is to cut the amount of food that is wasted and lost all over the world by fifty percent by the year 2030. This aim was established as part of the Sustainable Development Goals. On the other hand, research on PHL has not gotten the attention that it deserves; less than five percent of the cash that is committed to agricultural research all over the world is devoted to tackling this problem [7] . This is a significant gap in the research community. In order to accomplish the purpose of this review, an analysis of the current literature on PHL will be carried out. This study will include a discussion of the factors that contribute to it, as well as technology and prospective techniques for its reduction. Additionally, it addresses issues about phytosanitary hazards both on and off farms, as well as the social and environmental aspects of PHL. Finally, it discusses the implications of PHL. In addition to the aforementioned topics, this particular topic as well is discussed [8] . Post-harvest losses refer to the reduction in the quantity or quality of agricultural produce between the time of harvest and consumption. These losses can occur during harvesting, handling, processing, storage, and transportation. They encompass physical losses, such as spoilage and damage, as well as qualitative losses, like deterioration in taste, texture, and nutritional value. Post-harvest losses affect a wide range of products, including fruits, vegetables, grains, and livestock products, and can be attributed to various factors including inadequate infrastructure, poor handling practices, and environmental conditions [9,10] .

Statistical Impact on Global Food Security and Economy

Globally, post-harvest losses are a significant concern. According to the Food and Agriculture Organization (FAO), approximately 14% of global food production is lost after harvest but before reaching the consumer [11] . This translates to about 1.3 billion tons of food annually, worth around $940 billion. In developing countries, where infrastructure and technology are often lacking, post-harvest losses can reach up to 40% for certain crops. This not only impacts food availability but also exacerbates food insecurity, particularly in regions where food resources are already scarce. Economically, these losses reduce the income of farmers and increase the cost of food for consumers, contributing to inefficiencies in the global food supply chain [12] .

Economic Implications for Farmers and the Supply Chain

Addressing post-harvest losses is crucial for improving the economic viability of farming operations and the overall efficiency of the food supply chain. For farmers, reducing losses means increased revenue from higher yields and reduced waste. Improved handling and storage practices can lower costs associated with spoilage and damage, enhancing profitability [13] . On a broader scale, reducing post-harvest losses can lead to more stable food prices and increased availability, benefiting both producers and consumers. Effective management of these losses can also mitigate the economic burden on the entire supply chain, from logistics to retail [14] .

Environmental Impact of Wasted Resources and Energy

The environmental implications of post-harvest losses are significant. Wasted food represents not just a loss of edible produce but also a worthless investment in resources such as water, energy, and land. For instance, the production of food that ultimately goes to waste contributes to unnecessary greenhouse gas emissions and environmental degradation [15] . Moreover, the disposal of spoiled food adds to the burden on waste management systems and can lead to increased methane emissions from landfills. By addressing post-harvest losses, we can reduce the environmental footprint of agriculture, contribute to sustainable resource use, and help combat climate change [16] .

How Engineering Solutions Can Address Inefficiencies and Improve Storage, Handling, and Transportation

Engineering innovations play a pivotal role in mitigating post-harvest losses by addressing inefficiencies in storage, handling, and transportation. Advanced engineering solutions, such as temperature-controlled storage systems and automated handling technologies, can significantly reduce spoilage and damage. For example, modern refrigeration systems and controlled atmosphere storage can maintain optimal conditions for preserving perishable produce [17] . Automated sorting and packing systems minimizes physical handling and reduce damage during processing. Additionally, smart transportation solutions, including temperature-regulated vehicles and GPS-based route optimization, ensure that produce is transported under ideal conditions, minimizing losses during transit. By integrating these engineering advancements, the agricultural sector can enhance efficiency, extend shelf life, and ultimately reduce post-harvest losses [18] .

Understanding Post-Harvest Losses

Post-harvest losses encompass various forms of waste and deterioration that occur from the time of harvest until the produce reaches the consumer. Understanding these losses is crucial for developing effective strategies to minimize them and improve the efficiency of the food supply chain [19] .

Types of Post-Harvest Losses Physical Losses

Physical losses refer to the tangible reduction in the amount of produce due to spoilage and damage. These losses can occur at multiple stages:  Spoilage: This involves the decay or deterioration of produce due to microbial activity (Bacteria, fungi, and moulds) or enzymatic processes. Spoilage can be accelerated by factors such as inadequate temperature control, high humidity, and poor sanitation. For instance, fruits and vegetables may develop mould or rot if not stored properly [20] .  Damage during Handling and Transport: Physical damage often occurs during the handling and transportation phases. Rough handling, inadequate packaging, and improper loading and unloading can cause bruising, crushing, and other forms of mechanical damage. For example, delicate fruits like berries can be easily crushed during transport if not handled with care, leading to a significant reduction in marketable quality [21] .

Quantitative Losses: Quantitative losses involve a reduction in the measurable aspects of produce, including:  Loss of Weight: Weight loss can occur due to moisture loss, a common issue with fruits and vegetables. This can result from improper storage conditions or prolonged exposure to air. For example, root vegetables like carrots may lose weight and become less marketable if they dry out [22] .  Loss of Volume: Volume loss can result from shrinkage or drying, affecting the overall quantity available for sale. This is particularly relevant for products like grains and pulses, where prolonged exposure to moisture or poor storage conditions can lead to a reduction in volume [23] .  Nutritional Quality: Post-harvest losses can also affect the nutritional value of produce. The breakdown of vitamins, minerals, and other nutrients can occur due to factors such as prolonged storage, exposure to light, and temperature fluctuations. For instance, vitamin C content in fruits can degrade over time if not stored under optimal conditions [24] .

Qualitative Losses

Qualitative losses refer to changes in the sensory and aesthetic attributes of produce:  Changes in Taste: The flavour profile of produce can be adversely affected by post-harvest conditions. For example, overripe fruits may become overly sweet or develop off-flavours due to enzymatic changes or microbial contamination [25] .  Changes in Texture: Texture changes can occur due to moisture loss or softening. Vegetables might become limp or mushy, while fruits may lose their crispness or become mealy. These changes can make the produce less appealing to consumers [26] .  Changes in Appearance: Visual quality, including colour and shape, can be compromised by post-harvest losses. Discoloration, wrinkling, or blemishes can reduce the marketability of produce. For example, potatoes might develop sprouting or greening, affecting their appearance and quality [27] .

Common post-harvest losses in fruits, including their causes and potential solutions [28,29,30,31] :

Causes of Post-Harvest Losses

Post-harvest losses can be attributed to various factors that affect the quality and quantity of agricultural produce. Identifying and understanding these causes is essential for implementing effective solutions to minimize waste and improve food security. The primary causes of post-harvest losses include inadequate storage facilities, poor handling and transportation practices, and environmental factors [41] . [42] .  Limited Capacity: Storage facilities may be inadequate in capacity, forcing producers to store excess produce in suboptimal conditions or sell it quickly at lower prices. This lack of capacity can lead to overstocking, where produce is not handled or stored efficiently, increasing the risk of loss [43] .

Inadequate

Poor Temperature and Humidity Control

 Inadequate Climate Control: Effective storage requires controlling temperature and humidity to maintain the quality of perishable produce. Many storage facilities lack advanced climate control systems, leading to conditions that promote spoilage. For example, fruits and vegetables may rot if stored in environments with high humidity or fluctuating temperatures [44] .  Lack of Insulation: Poor insulation in storage facilities can lead to temperature variations, affecting the shelf life of stored produce. Without proper insulation, the internal environment may not be maintained consistently, leading to temperature extremes that accelerate spoilage of perishables [45] .

Poor Handling and Transportation Practices 1. Inadequate Handling Procedures

 Rough Handling: Improper handling during harvesting, sorting, and packing can cause physical damage to produce. For example, dropping or throwing produce can lead to bruising, cuts, and other forms of mechanical damage that reduce quality and marketability [46] .  Lack of Training: Farmers and workers may lack proper training on handling techniques, leading to inefficient practices that increase losses. Training on gentle handling and proper sorting can significantly reduce damage and waste [47] .

Inefficient Transportation

 Suboptimal Packaging: Poorly designed packaging may fail to protect produce during transportation. Inadequate packaging can lead to crushing, bruising, or exposure to environment. For instance, produce transported in non-ventilated containers may suffer from moisture accumulation and spoilage [48] .  Delayed Transit Times: Long transportation times and delays can increase the risk of spoilage, especially for perishable produce. Inefficient logistics and inadequate transportation infrastructure can result in extended transit times, affecting the quality of produce by the time it reaches its destination [49] .

Environmental Factors 1. Temperature Variations

 Extreme Temperatures: Exposure to extreme, whether like hot or cold, can significantly impact the quality of produce. High temperatures can accelerate ripening and spoilage, while low temperatures may cause freezing or chilling injuries. For example, vegetables like lettuce can suffer from bolting and wilting if exposed to high temperatures during storage [50] .  Fluctuating Conditions: Temperature fluctuations can lead to condensation and mould growth, further contributing to spoilage. Maintaining a constant temperature is crucial for preserving the quality of stored produce [51] .

Humidity Levels

 Excessive Humidity: High humidity levels can promote the growth of moulds and fungi, leading to spoilage and disease. For instance, grains and cereals stored in humid conditions may become infested with pests or develop mould, reducing their quality and usability [52] .  Low Humidity: Conversely, low humidity can cause produce to dry out, leading to shrinkage and loss of weight. Proper humidity control is essential to prevent both excess moisture and excessive dryness [53] .

Pests and Diseases

 Infestation by Pests: Insects and rodents can cause significant damage to stored produce. Pests can feed on grains, fruits, and vegetables, leading to direct loss and contamination. Implementing effective pest control measures is crucial for reducing these types of losses [54] with recommended practices while using pesticide.  Disease Spread: Fungal, bacterial, and viral diseases can spread rapidly in poorly managed storage environment. For example, a single infected fruit can lead to the spread of disease to other produce, resulting in widespread losses [55] .
