Asian Food Image Classification Based on Deep Learning

To improve Asian food image classification accuracy, a method that combined Convolutional Block Attention Module (CBAM) with the Mobile NetV2, VGG16, and ResNet50 was proposed for Asian food image classification. Additionally, we proposed to use a mixed data enhancement algorithm (Mixup) to have a smoother discrimination ability. The effects of introducing the attention mechanism (CBAM) and using the mixed data enhancement algorithm (Mixup) were shown respectively through experimental comparison. The combination of these two and the final test set Top-1 accuracy rate reached 87.33%. Moreover, the information emphasized by CBAM was reflected through the visualization of the heat map. The results confirmed the classification method’s effectiveness and provided new ideas that improved Asian food image classification accuracy.

The food standardization statusquo and development trend of developedcountries,such as the U.S.,Canada,Japan,etc.are analyzed and researched in this paper.Some practical and effective measuresthat should be taken in the food standardizationof China are advised to promote the expeditiousdevelopment of China's food standardization,to improve food quality and safetyand to increase the international competitionof food industry in China.

Impact of Food Safety Standards on Food Export

This article research the food quality standards covered global and international regulations on food safety and quality, and public and private standards. The effect of global character of food safety and quality standardization shows that the important effect is increasing marginal costs of certification and accreditation, which puts pressure on export company profits in different countries. Main conclusions yield insights into the key following points： Increased food safety has been associated with higher income. Consumers and governments can afford to focus more on reducing food-borne safety risks once basic quantity needs for foods have been met or are in the process of being met. This suggests that policies focused on increasing income are the surest path to improving food safety in all countries. Food safety regulations should be designed to meet the food safety demands of consumers in rich countries and, at the same time, further the interests of both consumers and producers in poor countries.

Factors Influencing Food Enterprises' Implementation of ISO9000 Series Standards from the Perspective of Economy and System

Currently, the food security situation is increasingly serious, and a growing number of food companies choose to implement the internationally accepted ISO9000 Series Standards. Based on the analysis of economic rationality and system drive for food enterprises to implement ISO9000 Series Standards, we determine the economic factors and institutional factors influencing enterprises' implementation of ISO9000 Series Standards, and establish corresponding indicator system. According to survey data on 86 enterprises in Sichuan Province, we draw the following conclusion using the Logit model: enterprise age and enterprise size in economic factors, government's food safety control intensity, consumers, public and media pressure, awareness of senior managers, strategic orientation of quality safety, employees' average educational level in institutional factors, have a significant effect on enterprises' implementation of ISO9000 Series Standards. According to research results, we put forth some recommendations for promoting food enterprises to implement ISO9000 Series Standards.

Relevance of a standard food model in combination with electronic jaw movement recording on human mastication pattern analysis

The aim of this paper is to describe the possibilities of analyzing human mastication. The development of a standardized food model is presented. Based on the findings of a systematic literature search an elastic food model was created with the aim of standardizing size and elastic properties. Three different eatable jellied products were chosen, created by a changing of the amount of gelatin (260 Blooms) related to the total mass of the standard jellied food. The different hardness were classified in soft, medium and hard, flavored identically, but stained with different colors: soft-green, medium-yellow, hard-red. A cylindrical form was chosen with a height of 1 cm and a diameter of 2 cm. A standard protocol for analyzing chewing patterns in men was created. The condylographic data off several patients are described in details to demonstrate the possible clinical implementation. The newly developed standard food model (SFM) showed the capability to serve in experimental settings to analyze human mastication, although only a few patients have been examined. In addition, strength and size of the newly developed SFM load the masticatory system in an extent;it should be possible to disclose subclinical symptoms of patients within a short time of examination. The diagnostic procedure of temporo-mandibular disorder (TMD) should be endorsed by this new method. The condylographic data created by a standardized protocol should have the ability to enhance the clinical functional analysis of patients previous to restorative dental procedures.

An SLGC Model for Asian Food Image Classification

As a fine-grained classification problem, food image classification faces many difficulties in the specific implementation. Different countries and regions have different eating habits. In particular, Asian food images have a complicated structure, and the related classification methods are still very scarce. There is an urgent need to develop a feature extraction and fusion scheme based on the characteristics of Asian food images. To solve the above problems, we proposed an image classification model SLGC (SURF-Local and Global Color) that combines image segmentation and feature fusion. By studying the unique structure of Asian foods, the color features of the images are merged into the representation vectors in the local and global dimensions, respectively, thereby further enhancing the effect of feature extraction. The experimental results show that the SLGC model can express the intrinsic characteristics of Asian food images more comprehensively and improve classification accuracy.

Food Safety & Standards

An increasing number of people have realized that food safety is an important issue for public health. It not only concerns public health and safety, but also has direct influence on national economic progress and social development. The development and implementation of food safety standards play a vital role in protecting public health, as well as in standardizing and facilitating the sound development of food production and business. After China became a WTO member, food safety standards, which have been indicated by Application Agreement of Sanitary and Phtosanitory Measurements (SPS Agreement) of WTO as the sanitary measurement for food import and export, have a special and great influence on Chinese food industry and trade. The development and revision of food safety standards have drawn great concerns from all stakeholders including the government, food industries and consumers.

Private- Sector Standards Regulation with Food Safety in China：Can It Learn Anything from WTO？

It is predicted that in the near future,private- sector standard will,like Tesco,Wal- Mart,Carrefour,still exit. China should modify its current legal regal disciplines' to make the private entities with regards food safety. Probably the mechanism of government-private entities collaboration governance would be a best choice.

No country is an island in regulating food safety:How the WTO monitors Chinese food safety laws through the Trade Policy Review Mechanism(TPRM)

Established within the framework of the World Trade Organization （WTO）, the Trade Policy Review Mechanism （TPRM） reviews periodically the trade policies of all WTO Members. The review includes many aspects of food safety regulation. China＇s trade policy is reviewed every two years. This paper analyses in detail the reviews of China＇s trade policy in 2006, 2008, 2010, 2012 and 2014. It focuses in particular on food safety laws and types of standards, alignment of domestic standards with international standards, the role of different domestic institutions, transparency and notification of food safety measures under the WTO agreements on Sanitary and Phytosanitary Measures （SPS） and on Technical Barriers to Trade （TBTAgreement）, import and export, and geographical indications （GIs）. It concludes that the WTO TPRM can contribute, within its mandate, to reform of Chinese food safety laws and improvement of food safety in China. it notes that China has already undertaken substantial reforms of its system for regulating food safety. It recommends that China should continue to participate actively in the TPRM, follow its own path with regard to alignment and learn selectively from other WTO Members.

Visualization analysis of the international standard ISO/TC 249 for traditional Chinese medicine

Objective This study proposes to visually review the current situation and progress of standards sets by the International Organization for Standardization/Technical Committee on Traditional Chinese Medicine(ISO/TC 249). The review aims to explore the development strategies of the standards, which will exhibit the considerable impact on the economy, trade and exchanges, and cooperation in the area of traditional Chinese medicine(TCM).Methods ISO/TC 249 standards were searched on the ISO website, and their title, proposed time, current stage, scope, and classification were obtained for further summarization. Gephi was utilized to portray the co-occurrence network graph of the ISO/TC 249 standards subject.Results In ISO/TC 249, there were 116 standards, including 81 published standards and 35 developing standards by April 30, 2022. Two withdrawal standards were published after revision, which were not counted in the total standards. The number of published standards has been increasing since the first standard was published in 2014, whose title was “Sterile acupuncture needles for single use”. Among these standards, 17.24%(20/116) standards were in review, 56.03%(65/116) in publication, 3.45%(4/116) in approval, 5.17%(6/116) in enquiry,3.45%(4/116) in committee, and 14.66%(17/116) in preparation, respectively. With 116 standards, most of the research focused on the medicament, as its classification of the International Classification for Standards(ICS) showed the proportion reaching 49.54%. The network analysis data revealed that the top five most frequent words were “materials” “root” “requirements” “products” and “system”, after removing the noise data, such as prepositions,conjunctions, and pronouns. Additionally, the word “system” co-exists with the terms “computerized” “coding” “image” “tongue” and “analysis”;the word “requirement” co-exists with“manufacturing” “decoction” “process” and “materials”;whereas the word “devices” coexists with “pulse” “electric” “skin” and “measurement”.Conclusion With the increased diversification and complexity of problems, the development of standards is also oriented to multidisciplinary fields to cultivate the interdisciplinary talents, and especially the international standardization talents of compound TCM. Multi-angle analysis, formulation, and demonstration of standards, in line with industry needs in different disciplines, enhance the availability of standards and the ability to serve the industry.
