Principle and applications of near‐infrared imaging for fruit quality assessment—An overview

SummaryThe quality (i.e. the degree of excellence and acceptance to the consumer) evaluation and safety of fruit and other agricultural products is by far the main challenging task in the food industries. Hence, the development of efficient non‐invasive, real‐time and rapid‐quality assessment tools and techniques is the need of the hour. This review paper aims to provide the basic or fundamental knowledge regarding the principle, potential and application of near‐infrared imaging‐based computer vision systems. Non‐invasive technologies, based on optical properties, are the most applicable and important for real‐time quality assessment. Absorption, reflection and scattering before the transmission of incident light are phenomenon properties of biological materials. The principle and application of NIR imaging (i.e. medical imaging) in agriculture for quality detection were studied from various published research papers. Thus, collected pieces of information are summarised, concluded and discussed in a unique way in this report. The NIR spectrum of electromagnetic waves has some basic benefits of light penetration into the upper layer and makes visualisation of the targeted area of objects. Several studies have proved that the non‐destructive system based on visible and non‐visible imaging in combination has a significant role in quality defect detection in fruits. In NIR imaging, the artefacts caused by light illumination can be reduced and it will help in the visualisation of biological tissues and hidden defects just below the peel.

Dissipation, residues and risk assessment of lufenuron during kumquat growing and processing

Dissipation, residues and risk assessment of lufenuron during kumquat growing and kumquat processing were investigated under field and household conditions. The QuEChERS technique with high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) was used to detect lufenuron residues content in kumquats and its processed products. The recoveries were 82.3–102.8% at a spike level of 0.005–0.5 mg kg−1, the relative standard deviations (RSDs) were 1.1–9.4%. The dissipation kinetics data showed that lufenuron in kumquats were degraded with the half-lives of 9.12–12.60 days. The terminal residues of lufenuron in kumquats were 0.064–0.107 mg kg−1 after application one times with a pre-harvest interval (PHI) of 14 days under the designed dosages. The juicing process can significantly reduce the residues of lufenuron in kumquats juice, and the processing factor (PF) value of juicing process was 0.15. The chronic dietary exposure assessment risk quotient (RQ) values of lufenuron in kumquats fruit and juice for different consumers were 0.71–2.13% and 0.37–0.86%, all of the RQ values were lower than 100%. The results from this study are important reference for Chinese governments to develop criteria for the safe and rational use of lufenuron on kumquats and monitor the quality safety of agricultural products and protecting consumer health.

Determination, residue analysis and risk assessment of thiacloprid and spirotetramat in cowpeas under field conditions

The dissipation and residue levels of thiacloprid, spirotetramat and its four metabolites residues in cowpeas were investigated under field conditions. The QuEChERS technique with high-performance liquid chromatography tandem mass spectrometry (HPLC–MS/MS) was used to detect thiacloprid, spirotetramat and its four metabolites residues content in cowpeas. The recoveries were 81.3–95.1% at a spike level of 0.005–0.5 mg/kg, the relative standard deviations (RSDs) were 2.1–9.5%. The dissipation kinetics data showed that thiacloprid and spirotetramat in cowpeas were degraded with the half-lives of 1.14–1.54 days and 1.25–2.79 days. The terminal residues of thiacloprid and spirotetramat were 0.0255–0.4570 mg kg−1 and 0.0314–0.3070 mg kg−1 after application 2 times with a pre-harvest interval (PHI) of 3 days under the designed dosages. The chronic and acute dietary exposure assessment risk quotient (RQ) values of thiacloprid in cowpeas for different consumers were 2.44–4.41% and 8.72–15.78%, respectively, and those of spirotetramat were 1.03–1.87% and 0.18–0.32%, respectively, all of the RQ values were lower than 100%. The dietary risk of thiacloprid through cowpeas to consumers was higher than spirotetramat. The results from this study are important reference for Chinese governments to develop criteria for the safe and rational use of thiacloprid and spirotetramat, setting maximum residue levels (MRLs), monitoring the quality safety of agricultural products and protecting consumer health.

Brand Premium and the Quality and Safety of Agricultural Products: Examples from Rice Planting in Jiangsu Province

The quality and safety of agricultural products has always been a long-term problem that plagues the government and academia. Many scholars discuss the possibility of controlling the quality and safety of agricultural products from the external measure of strengthening government supervision of agricultural production and planting, but it is difficult to avoid the embarrassing situation of “supervision failure”. At the same time, due to the decentralized and fragmented characteristics of China’s agricultural operations, the government’s comprehensive supervision on the quality and safety of agricultural products will produce extremely high supervision costs. In this context, exploring the market incentive and restraint mechanism of agricultural product quality and safety control is a hot topic of general concern of the government and academia.Based on the perspective of branding, this paper explores the impact of brand premium on rice quality and safety from the perspective of pesticide application through the theoretical and empirical analysis. The main research conclusions include: Firstly, traditional rice production is still dominated by traditional production and management methods, and the level of branded production is still at a low level as a whole. Secondly, the excess profits brought by brand premium can make up for the externality of agricultural safety production, allowing farmers to generate endogenous prices to encourage high-quality and safe agricultural production, thereby promoting the improvement of agricultural product quality and safety. Finally, there are certain boundary conditions for brand premium to promote the quality and safety of agricultural products. Only when the brand-specific assets restrict the production behavior of farmers, can the brand premium improve the quality and safety of agricultural products to the greatest extent. This paper thinks that in the process of agricultural product branding development, we should focus on the right and responsibility docking of brand subjects, and strengthen the binding effect of brand reputation, so as to give full play to the role of price mechanism in the promotion of agricultural product quality and safety.The innovation of this paper lies in the following three points: Firstly, scholars mostly explore the ways to improve the quality of agricultural products from the aspects of government supervision and the characteristics of farmers’ endowments, but there is a lack of discussion on the marketization mechanism of quality and safety improvement. This paper focuses on the price mechanism to solve the quality and safety problems, and the research perspective has certain novelty. Secondly, the existing discussion on the brand and quality safety of agricultural products lacks in-depth mechanism analysis and corresponding empirical support. This paper adds the correlation analysis of asset specificity and quality and safety cognition, and further clarifies the boundary conditions for brand premium to improve the quality and safety of agricultural products. Thirdly, in the process of analysis, we also pay attention to the differences of brand with different property rights in improving the quality and safety of agricultural products, and the relevant research is more specific and detailed.

Quality safety of agricultural products in supply chain-computer simulation based on multi-agent system

As is known that, one of the challenges in ensuring the quality and safety of agricultural products in China is how to organize plenty of scattered small farmers and integrate them into the modern agricultural products supply chain system. In this paper, in order to promote the tight integration of agricultural products supply chain, based on multi-agent system, a computer simulation model of agricultural products supply chain is proposed. Through a series of simulation experiments, the evolution of the organizational structure of the agricultural products supply chain, its impact on the quality and safety of agricultural products under different government regulations are explored and discussed in detail. It follows from these simulation results that the more long-term-contract farmers and sellers, the more conducive to the improvement of the quality and safety of agricultural products, and the corresponding countermeasures and suggestions are also provided.

Vertical Integration of Agricultural products supply chain and quality Safety of Agricultural products

Today, food safety is a common concern in the world. As the main source of food, agricultural products’ safety is also worthy of attention. By establishing the vertical integration model of the agricultural product supply chain, the circulation links of agricultural products can be reduced, and the circulation efficiency and quality level of agricultural products can be improved. This paper assumes that under the condition of simple fresh agricultural products, there is only one wholesaler and one retailer in the agricultural product supply chain. Through the analysis of the economic model, it is concluded that the vertical integration of the agricultural product supply chain has a positive impact on the safety of agricultural products. With the improvement of the vertical integration of the supply agricultural products supply chain, the efforts of wholesalers and suppliers to ensure the safety of agricultural products have been improved, the circulation cost of agricultural products has been reduced, and the sales price of agricultural products has been reduced.

Application of Combination Evaluation Method in Evaluation of Green Agriculture Development Level in China

The first document of the central government in 2021 proposed to strengthen the supervision of agricultural product quality and food safety, and vigorously develop green food and organic food. Green agriculture is the core of the future development of modern agriculture, which is closely related to food safety, environmental protection and sustainable use of resources, and is the basis for realizing agricultural and rural modernization. In this paper, three objective weighting methods (entropy method, principal component analysis method, factor analysis method) were used to assign the weight of China's green agriculture development level index in 2018, and then combined with the combination evaluation method to calculate the comprehensive score and ranking. On this basis, the 31 provinces and cities in China were divided into four types by cluster analysis: high level of green agriculture development, high level of green agriculture development, medium level of green agriculture development and low level of green agriculture development. According to the study, Heilongjiang, Shandong, Jiangsu, Henan and Anhui were the regions with higher green agriculture development in 2018. On the other hand, the five least developed provinces and cities are Beijing, Ningxia, Hainan, Tianjin and Tibet. The overall situation of green agriculture development in China is unbalanced among regions. Therefore, according to the agricultural economic basis of each province or city, some suggestions are put forward in the hope of improving the agricultural production environment, improving the quality of green agricultural products, realizing the balanced development of green agriculture among regions and speeding up the process of agricultural and rural modernization.

The degradation behaviour, residue distribution, and dietary risk assessment of malathion on vegetables and fruits in China by GC-FPD

The gas chromatography-flame photometric detector (GC-FPD) was used to detect malathion residues content in vegetables (cherry tomatoes and broccoli) and fruits (mulberries, cranberries, and figs). The recoveries of samples were 76.2 ± 3.5%–103.9 ± 3.6% at a spike level of 0.01–10 mg/kg, the relative standard deviation (RSDs) were 2.1%–7.3%, and the limit of quantification (LOQs) were 0.01–0.02 mg/kg. On the basis of the normative field trials, the degradation half-life of malathion were 1.10–2.15 days, which indicated that malathion degrades quickly. The final distribution of malathion residues in various vegetables and fruits varied from <0.01 to 0.58 mg/kg. The long-term dietary risk assessment results showed that the national estimated daily intake (NEDI) of malathion in various populations of China ranged from 0.000021 to 0.000549 mg/kg bw, and the risk quotient (RQ) ranged from 0.007% to 0.183% and were less than 100%, which indicated that malathion has a low risk for long-term dietary intake these crops. The maximum residual limits (MRLs) of malathion can be set as 1 mg/kg for cherry tomatoes, broccoli, mulberries, cranberries, and 0.2 mg/kg for figs, respectively. These results would be considered as important references for monitoring and assessing the quality safety of agricultural products and protecting consumer health.

Determinants of Breeding Farmers' Safe Use of Veterinary Drugs: A Theoretical and Empirical Analysis.

As food safety has attracted the widespread attention of society, the quality safety of agricultural products has become an important part of food safety and also confronts multiple challenges. In fact, the safe use of veterinary drugs in the production process has become one of important guarantees for the quality safety of agricultural products. It’s of great significance to regulate the breeding farmers’ safe use of veterinary drugs and to create a safe and healthy production environment for agricultural products. A field survey of individual and large-scale swine breeding farmers in four typical provinces including Henan, Shandong, Jiangxi and Guizhou generated 397 questionnaires. This field survey conducted the internal and external classification of breeding farmers’ safe use of veterinary drugs and defined the breeding farmers’ safe use of veterinary drugs in the light of dosage, type and standardized operation of veterinary drugs. Based on Lewin’s behavior theory, the survey used the structural equation modeling method to systematically examine the generation path of breeding farmers’ safe use of veterinary drugs. The comprehensive analysis reveals that breeding farmers’ knowledge about veterinary drugs, the attitudes toward the government supervision and the market environment of breeding activities all exert some effects on breeding farmers’ use of veterinary drugs. Some suggestions and countermeasures for breeding farmers’ safe use of veterinary drugs are provided as follows: First, more efforts should be pumped into publicity and instruction so that breeding farmers can have a better understanding of veterinary drugs. Second, preferential policies should be formulated to encourage the breeding farmers’ participation in the industrial organizations of swine breeding farmers, and advocate the industrial organizations’ active provision of different technical trainings. Third, the communication and cooperation platform should be created among breeding farmers, slaughter and processing plants and supermarkets, the poultry insurance market should be regulated, and the insurance purchase process should be improved. Fourth, when more subsidies for harm-free and environment-friendly veterinary drugs are provided, more serious punishments should be imposed on the unsafe use of veterinary drugs to offer policy support for the breeding farmers’ standardized use of veterinary drugs.

Incentive Decision on Safety Investment of Supply Chain of Agricultural Products in “Agricultural Super-Docking”

Since the “agriculture super-docking” mode was introduced in China in 2007, remarkable success has been made in reducing the transaction cost and improving the quality safety of agricultural products. However, the quality safety issues of agricultural products still occur frequently because both specialized farmers’ cooperatives and supermarkets have insufficient safety investment. In order to study the necessity, goal, and incentive decision schemes of safety investment in “agriculture super-docking” supply chain, three kinds of models, which include noncooperatives distributed decision-making model, centralized decision-making model, and incentive coordination models led by cooperatives and supermarkets, are, respectively, set up in this paper. Conclusions are drawn as follows: when making the uncooperative decentralized decision, both cooperatives and supermarkets have the moral risks to decrease the safety investment, but appropriate measures can achieve the coordination of the supply chain; when achieving the coordination of supply chain, the two contacts under the guidance of cooperatives and supermarkets are the same, and the schemes of distributing profits are also the same. Moreover, a practical case is given to improve the effectiveness and feasibility of the incentive decision schemes.
