Mycotoxins are toxic secondary metabolites produced by certain fungal species under specific conditions. Research has found that exposure to various fungal toxins can cause embryonic developmental toxicity, such as embryo arrest, abortion, and intrauterine fetal developmental delay. There are no systematic reports on the impact of exposure to fungal toxins during pregnancy on the toxicity of intrauterine fetal development and biological monitoring. Therefore, in order to prevent and reduce the harm of fungal toxins during pregnancy, this paper summarizes the research status of embryonic developmental toxicity, as well as the research status of biological monitoring technologies based on biomarkers such as exposure biomarkers and biomakers of effect, which are caused by traditional fungal toxins such as aflatoxin, deoxynivalenol, zearalenone, and emerging fungal toxins such as Alternaria toxins, beauverin, and enniatins. The aim of the paper is for construction of the healthy China.

Currently, there is a growing call for a co-governance approach that includes consumers in food safety governance. To address this, corporations have implemented decentralised digital food traceability systems based on blockchain. Many argue that this technology will lead to enhanced consumer trust in food safety governance through greater consumer engagement. In this regard, this paper examines factors that influence consumer engagement and trust in food safety governance, mobilising interdisciplinary literature from the social sciences, economics and food safety governance. By doing so, it explores the implications of the implementation of blockchain as a means of enhancing consumer trust. The paper raises critical questions on a global scale and offers a social science and wider empirical perspective that has received less attention. To further investigate the effects of blockchain on consumer trust in the food supply chain, it proposes a research agenda that includes theoretical and empirical research.

Green ecological control of stored grain pests is one of the important tasks to promote green grain storage. Predator mite control of stored grain pests is a biological control technology that employs ecological factors to suppress the population of stored grain pests. Cheyletus malaccensis control the pest populations by feeding on the eggs and larvae of insect pests and mites. As Cheyletus malaccensis is the dominant predatory mites in Chinese grain warehouse, it has several advantages, including wide distribution, large quantity, significant quantities, a broad predation spectrum, and high predation levels. This paper briefly described the control technique for stored grain pests by C. malaccensis and the advantages of control by C. malaccensis based on our team's researches in recent years. In addition, low-cost and convenient artificial propagation and release technologies have been developed. These methods are non-polluting, residue-free and are effective in preventing resistance within warehouse applications. This paper provides guidance for the green, ecological and safe stored grain pests comprehensive control and for reduced application of chemical pesticides.

The shortage of high-quality protein feed resources has become an important variable affecting food security in China.

Compared with the advanced and sophisticated industrial production, agriculture and food production appear backward and sloppy, and agricultural production management methods are lacking. The fourth industrial revolution, represented by information technologies such as intelligent perception, Internet of Things, block chain, big data and artificial intelligence, has empowered traditional industries, and agriculture has stepped into a new digital, intelligence and even wisdom, which could provide a new opportunity to improve agricultural production management. Existing agricultural production management research is mostly limited to the study of concept definition, applicable theory and other issues. The development of information technology has built up a low-level Internet of Things with certain coverage, which brings some convenience, but cannot effectively support agricultural management and decision-making due to data silos, data waste, data abuse, data falsification and other thorny issues. From the perspective of top-level design and system management, this paper addressed the problems in the development of smart agriculture, conceptualized the characteristics of the event and natural event chains in the agricultural industry chain. This paper also proposed for the first time an event-correlation management approach and its wisdom strategy. The implementation of the event-correlation method included five aspects, including goal alignment, index systematization, asset linkage, process linkage and effect traceability. The application of the event-correlation management approach and its wisdom in the 5T management standard designation for Jilin rice brand building and the “six-step fresh rice precision control technology” innovation system of Wilmar rice industry have shown that it can improve the culture of rice cultivation, and systematically reduce losses to improve quality and increase economic benefits.

Based on the mathematical model of internal air flow, heat and humidity coupled transfer in paddy grain piles, while combined with the dynamic model of paddy yellowing, the paper adopted the method of numerical simulation to compare and study the variation of temperature, moisture content and paddy yellowing in the stored grain inside the shallow round warehouse under the conditions of annual natural storage and staged natural storage. On the basis of temperature and humidity, this paper further considered the yellowing effect on the quality of long-term storage of paddy. The results showed that, at the end of storage for 365 days, the average temperature of staged natural storage with ventilation was about 18 ℃ lower than that of natural storage throughout the year, the average moisture was about 0.5% lower, and the average yellowing value was about 0.8 lower. Low temperature air flowling into the high temperature granary could not only reduce the temperature, but also reduce the grain moisture and alleviate the process of paddy yellowing, so the phased natural storage was more conducive to the long-term quality storage of paddy. The rice near the warehouse wall was easily affected by the external ambient temperature, and the coating could be applied on the outside of the warehouse wall to reduce the influence of solar radiation.

ObjectiveTo infer the relationship between bisphenol A （BPA） exposure and adverse health effects in humans， the human epidemiological data of BPA was evaluated by the weight of evidence approach.MethodsBased on the weight of evidence approach， the human epidemiological research articles on BPA published between 2013 and 2020 were systematically searched， screened and classified. The selected articles were evaluated following the guidelines of evaluating the relevance and reliability of toxicological data developed by the China National Center for Food Safety Risk Assessment. The hazard assessment was performed based on different endpoints.ResultsA total of 188 papers were obtained screening from 134 897 records， of which 68 papers were evaluated as “A/B” or “B” in terms of relevance， and the rest were evaluated as “C”. Only the studies with the relevance evaluation grade of “A/B” or “B” were evaluated for reliability， of which 6 studies were evaluated as “high” reliability and 62 studies were evaluated as “medium” reliability. The endpoints of toxicological effects should include metabolic， reproductive and developmental， neurological， immunological and cardiovascular effects. However， the effect indicators across studies lacked consistency due to study population， exposure duration and indicator design.ConclusionBased on the available evidence of human epidemiological data， the relationship between BPA exposure and adverse health effects in humans is not yet clear.

Phosphine and sulfuryl fluoride are two kinds of fumigation insecticides allowed for use in China and overseas. Phosphine is the “trump card” fumigation insecticide for stored grain, while Sulfuryl fluoride is mainly used as the phosphine resistance management drug. Therefore, both of them are complementary to a certain extent. In view of the application status, problems, and challenges faced by the prevention and control of stored grain pests in China, this paper investigated and sorted out the basic technical characteristics, main production enterprises, production and sales, application technology, residual problems, disposal methods, and application dominance of global grain fumigation pesticide aluminum phosphide (phosphine). Combined with the domestic and international situation, this paper also summarized the technical characteristics, its relationship with phosphine, demand, application characteristics and existing problems of sulfuryl fluoride fumigation, and put forward the suggestions and necessity of systematically carrying out the research on sulfuryl fluoride fumigation and its impact on the environment, so as to comply with the concept of “green, ecological, economic and efficient” and provide reference for the scientific and technological development of stored grain pest control in China.

We researched label symbols and instructions of food contact products in China, expecting to provide technical guidance on label design regulation for manufacters. This paper summarizes the technical specification of food contact product labeling and instructions for use by reviewing domestic and international regulations on food contact product. This study finds that China’s standards do not specify that only products having passed the quality requirements of the national standards for food contact products can be marked with the "food contact" symbol, resulting in poor "Food contact" symbol brand effect. In addition, the standards do not have systematic and comprehensive regulations on the use of the product instructions and precautions. Therefore, this paper proposes to improve the relevant regulations and standards, so that the "food contact" symbol is linked to good quality of the product and brand effect can be strengthened. We also suggest to refine the instructions and precautions for use of regulations and standards, thereby promoting the standardization of the labeling of food contact products and instructions.

Millet crops are a general term of a class of annual crops with small grains, drought resistance, and barren resistance. Millets are mostly planted and consumed in developing countries in Asia and Africa. Foxtail millet and prosomillet are the most cultivated varieties in China. Governments of relatively developed countries in Asia, Europe and America pay more attention to scientific research and investment of millet crops rather than planting and consuming situation of that. The number of published papers on millet research supported by the National Natural Science Foundation of China ranks first in the world, followed by that funded by European Commission, the UK Research and Innovation Agency, and the US National Science Foundation. However, in the last five years, India published the most of research papers, followed by China and the United States. Millets have many health benefits due to their richness in dietary fibers, proteins, minerals polyphenols, et al., so food science and technology and plant science have been becoming the hottest research areas on millet. Finally, we described some traditional and industrial millet products.

Food safety is closely related to life and health, and the issues of food safety are related to people’s livelihood plan. Although the legal system of food safety in China has been gradually improved and the system of punitive damages has been established, it is not yet complete. The food safety punitive damages system defects and future improvement of the path are discussed in this article. This paper clarifies the nature and function of the punitive damages system for food safety, and discusses several key problems existing in this system. At present, there are some problems in the punitive compensation system of food safety in China, such as the unclear definition of the concept of the subjective elements, the unreasonable setting of the compensation amount, and the unclear subject status. As a result, there is no unified standard in judicial practice, and there are many phenomena of different judgments in the same case, which affects the function of this system. Therefore, this paper discusses the way to improve the punitive damages system of food safety as well as analyzes the system defects, proposes three main corresponding recommendations.

Taking the black sesame compound honey pill as the research object, the acid value and peroxide value are used as evaluation indicators to investigate the influence of different storage temperatures on its quality; on this basis, the shelf life of the black sesame compound honey pill under naked packaging conditions is predicted by constructing an Arrhenius model. In order to further extend the shelf life, four different packaging forms were set up to package the black sesame compound honey pill, and the effects of different packaging methods on its storage quality such as moisture, texture, and physical and chemical properties were investigated at the same time. The results showed that: compared with the control group, nitrogen filling, shelling and wax sealing have a certain effect on preventing the black sesame compound honey pill from decreasing moisture and increasing hardness and acid value. The packaging form of wax paper + pill shell + wax seal + tin foil paper + polyethylene plastic bag has the best effect. The research results provide a reference for the storage of honey pill products.

And storage time, temperature and humidity, storage quality, insects and mold were their main topics. In foreign countries, the scientific and technological institutions of various countries were the funding institutions, and the research institutions and individuals focused on six topics, such as grain storage, productivity analysis, food characteristics and microstructure properties. There is little cooperation among authors from different countries. The academic achievements had the largest number of papers published in “Journal of The Chinese Cereals and Oils Association” and “Journal of stored products research”.

In order to clarify the quality change of indica-japonica hybrid rice in different packaging，this experiment was conducted to study the effects of four packaging, woven bags, PE bags, vacuum packages and kraft paper bags, on the rice and steamed rice quality at room temperature (20~25 ℃) with YongYu 15 rice as raw material. The results showed that, with the extension of storage time, the fatty acid value, amylose content and rice hardness of indica japonica hybrid rice increased gradually, while the indexes of rice freshness value, taste value, viscosity and taste value of rice decreased gradually. The correlation between the quality indexes was significant (P PE bag > woven bag > kraft paper bag. The above results show that, the vacuum and barrier packaging could effectively delay the decrease of the quality of indica-japonica hybrid rice and its cooked rice, and improve its storage quality.

In this paper, wheat flour was irradiated at different doses (0, 5, 10, 15, 20 and 25 kGy) to investigate the effects of 60Co-γirradiation on the structural and functional properties of its gluten. The disulfide bond was broken by irradiation, and the content of the free sulfhydryl group increased. The results of Fourier infrared spectroscopy showed that the secondary structure of gluten protein was rearranged with decrease in a-helix content and an increase in β-sheet content. Raman spectroscopy and surface hydrophobicity showed that the microenvironment of aromatic amino acid side chains changed. Irradiation treatment resulted in the tryptophan and tyrosine residues tending more toward the exposed state, and the surface hydrophobicity increased. Meanwhile, irradiation increased the solubility, water and oil holding, and emulsifying properties of gluten proteins, and the maximum value reached at 15 kGy（solubility is 0.46 mg/mL, water holding 3.13 g/g, oil holding 4.33 g/g, emulsification 6.669 m2/g）. In conclusion, the proper dose of gamma-irradiation can change the secondary and tertiary structure of gluten, and improve its functional properties such as solubility, water retention and emulsification, which is conducive to expanding the application space of gluten protein and providing theoretical references for industrial applications.

Granary is an important facility to ensure the safety of grain storage. The granary is a large closed space with dim lighting and poor air circulation. Operations such as fumigation and air conditioning increase personnel safety risks. The identification and analysis of abnormal behaviors of workers through security videos in the granary has become a key safe operations for workers as an important technical guarantee. This paper proposed a video recognition algorithm for abnormal behavior of workers in a granary based on a skeleton sequence multi-algorithm. First, the YOLOv3tiny model was used to quickly detect the human body, combined with Sort to track the motion trajectories of multiple targets, and the human skeleton coordinate sequence and weight information were extracted through the AlphaPose model. Then, based on the real spacial graph (RSG) composed of natural connection nodes of the human skeleton and virtual spacial graph (VSG) constructed by interconnecting the center of gravity of the virtual human body with the head, hands, and feet, the bin was extracted based on the balance of the interaction between the center of gravity of the human body dynamics and the hands and feet. Spatial characteristics of abnormal behavior of internal workers and spatiotemporal characteristics of concatenated temporal convolution (TC). Finally, a virtual-real combining spatial temporal graph convolution network (VR-STGCN) video recognition algorithm for abnormal behavior of granary workers was proposed. At the same time, a hybrid dataset was built, and comparative experiments and analysis were conducted between VR-STGCN and four algorithms such as SSD, PCANet, Two-StreamCNN, and STGCN. The results showed that all indicators of VR-STGCN were better than those of the other four algorithms. VR-STGCN can accurately identify abnormal behaviors such as falling, crawling, and lying down of people in the granary in complex environments such as insufficient light, multiple targets, and long distances. The recognition accuracy reached 97.7%, and the processing speed was 18.67fps, which can analyze the abnormal behavior of workers in real time. The research results could provide a new and efficient technology for the safety of granary workers in complex environments.

In this paper, the contents of 12 mineral elements in 100 samples of four types of takeaway fast food, including porridge and noodles, special snacks, Chinese fast food and Western fast food, sold in Beijing were analyzed by ICP-MS, and the RNI and UL values of the elements were used as the assessment criteria for preliminary dietary nutritional assessment of different age groups. The results showed that the range of mineral element contents in the samples was wide and the degree of dispersion was large. The intakes of Na, I and Cr could meet the daily dietary needs of the whole population in all types of takeaway samples, while the intakes of Ca, Mg and Fe were insufficient. The insufficient intakes of K, Zn, Cu, Mn, Mo and Se were found in some of the samples of some populations. The intakes of the 12 elements showed different degrees of variability among the four types of takeaways, with lower intakes of each element in congee and noodle dishes, and K, Ca, Mg, Zn, Fe, Se and Cr showed significant differences from the other three types. The intake of each element was lower in congee and noodles, which showed significant differences with the other three categories. In addition, the intake of take-away fast food was found to be excessive, with Zn and I exceeding 1.1%~5.3% and 3.6%~14.3%, respectively, in different age groups. The results showed that the long-term take-away population should pay attention to adjusting their dietary structure, balancing the intake of take-away food containing meat, vegetables, legumes, eggs and milk, and appropriately replenishing various types of minerals with insufficient intake. At the same time the health risks of “over-nutrition” brought about by fast food takeaways should be paid attention, and the young minors were the key concern groups.

Edible vegetable oils could provide energy, essential fatty acids and various micronutrients required in the body.
