  • HACCP procedures are regarded as essential components of modern safety assurance programs for all forms of food processing and preservation, including irradiation. Control of hazards and classification of hazardous microorganisms and indicator organisms (and related tests) are helpful to establish preventive and practice regulations at each facility. A carefully conceived and well implemented system assure the safety of all products. The HACCP is designed to prevent defects, rather than to detect them as in traditional end-point testing and inspection, as controlling requirements into food formulations, processing parameters and operating practices. This article commentes on some equipments and materials for HACCP system.

  • The antioxidative activities of the water solution of crude extract from edible mushroom enokitake Flammulina velutipes were compared with those of ascorbic acid and ascorbic acid 6-palmitate in oil-in-water (O/W) emulsions of cod liver oil. Oxidation of the emulsions was carried out at 40 and $50^{\circ}C$ in the dark. The antioxidant activities were measured by in vitro assay against oxygen uptake, 2-thiobarbituric acid value, hydroperoxide formation of the oils. Also, residual docosahexaenoic acid content was measured as indices of lipid oxidation. The cod liver oil in O/W emulsions with added enokitake crude extract (ECE) was significantly more stable against lipid oxidation than the control emulsions without the extract in terms of any oxidation indices used. Moreover, ECE provided remarkable antioxidative properties to eicosapentaenoic acid ethyl ester in emulsion system. These observations demonstrate that F. velutipes can be used as a natural antioxidant, which effectively prevents oxidation of polyunsaturated oils in emulsion system.

  • This study examined the influence of social responsibility awareness (economic and social-environmental responsibility) and trust in corporate social responsibility on sustainable diets. The subjects of the study were 468 university students. The main research results were as follows. First, the social responsibility awareness of the study subjects was 4.03±0.72 points for economic responsibility and 3.48±0.81 points for social-environmental responsibility. An awareness of economic responsibility showed differences according to gender. Trust in corporate social responsibility was 3.62±0.61 points, and there was no statistical significance based on gender. Second, the level of a sustainable diet was food safety and consideration (4.06±0.63), knowledge of the environment and diet (3.94±0.68), understanding of the food circulation system (3.45±0.77), and healthy diet (3.26±0.89). Among the factors influencing a sustainable diet, female students had higher attitudes toward food safety and consideration and understanding of the food circulation system than male students. Third, the social responsibility awareness (economic responsibility and social-environmental responsibility) and corporate social responsibility trust variables influenced university students' sustainable diet. Among these, social-environmental responsibility awareness had the highest influence.

  • Objectives : This article reviews a solution preventing the illegal distribution of herbal medicine in common use for food and medicine and risks on public health by conducting safety management of food and medicine. Also, this article would like to contribute to improvement of public health treating diseases in compliance with accurate diagnosis and prescription of Oriental Medicine Doctor("OMD")'s. Methods : An approach in this research can be categorized into two : first, to examine the current administrative situation and problems of herbal medicine in common use for food and medicine based on policy documents of Ministry of Health and Welfare and Korea Food and Drug Adminstration("KFDA") and academic articles of the herbal medicine;second, to find reasonable administrative solutions to solve the problems. Solutions : A solution is to strengthen the management level of herbal medicine in common use for food and medicine by selecting 117 items as target items requiring concentrated management. In case herbal medicine is imported for food, KFDA strengthens the quality management level of herbal medicine by making use of inspection frequency at random, collecting and verifying herbal medicine on the market. However, KFDA decides to maintain current different quality specification system of food and medicine reflecting a civil complaint that quality specification of food and medicine should separately managed according to the purpose of use. Herbal medicine as medicine that is functioned as treating diseases and alleviating symptoms, unlike herbal medicine for food, can cure all kinds of diseases by recovering inner balance of human body, making use of other properties of herbal medicine. Medicine has its own properties. If a doctor uses properties of medicine appropriately, he cures diseases. If a doctor uses herbal medicine inappropriately. he may damage human body. Thus, whether side effects of medicine depend on a doctor who uses herbal medicine. Conclusions : All herbal medicine will be supplied into the market after strict safety control of manufacturers of herbal medicine according to the revised Pharmaceutical Affairs Act, beginning in April, 2012. Thus, people can take safer and more reliable herbal medicine through strengthening safety management of herbal medicine and improving quality and transparency in the distribution system. Herbal medicine should appropriately be prescribed by licensed OMD because herbal medicine is used to treat diseases and alleviate symptoms, unlike herbal medicine for food.

  • To develop ready-to-eat (RTE) style Korean traditional Galbi-jjim, the optimal conditions for sous-vide cooking and cookchill preparation and the sensory properties of the cooked products were investigated. During heating, the meat core temperatures reached $85^{\circ}C$ within 30 min and 45 min when a water bath and combination oven were used, respectively. Chilling to $3^{\circ}C$ within 45 min was conducted to meet the standards for microbiological safety set by the UK Department of Health and Social Security (DHSS) Guideline. Galbi-jjim that was vacuum-cooked in a water bath was much more tender than that of Galbi-jjim prepared using the cook-chill method, but had no difference in any reheating methods. The average sensory scores of juiciness and the overall acceptance of Galbi-jjim were significantly higher when water bath cooking was used, and there were no differences in reheating methods. In conclusion, the serial methods of sous-vide processing and rapid chilling can be applied to produce RTE traditional Galbi-jjim, and this can be conducted while meeting the standards specified in safety guidelines.

  • Facing a number of global food-related accidents, the concept and system for food traceability have been designed and introduced in many countries to manage the food-safety risks. To connect and harmonize the various food traceability-information in food traceability system according to the food supply chain, the coding system of identification-number for food-traceability has to be standardized. The GTIN (Global Trade Item Number) barcode system which has been globally standardized and implemented, is reviewed with the mandatory food-labeling regulation in expiration date of processed foods. The integration of GTIN-13 bar-code system for food-traceability is a crucial factor to expand its function in the food-related industrial areas. In this literature, the standard coding system of identification-number for food-traceability is proposed with 20 digit coding number which is combined with GTIN-13 bar-code (13 digit), expiration date (6 digit), and additional classification code (1 digit). This proposed standard coding system for identification-number has a several advantages in application for prohibiting the sale of hazard goods, food-recall, and inquiring food traceability-information. And also, this proposed coding system could enhance the food traceability system by communicating and harmonizing the information with the national network such as UNI-PASS and electronic Tax-invoice system. For the global application, the identification-number for food-traceability needs to be cooperated with the upcoming global standards such as GTIN-128 bar-code and GS1 DataBar.

  • This study was performed to develop children's food quality certification system as part of the children's favorite foods safety management projects. As a component of the research, we developed a quality certification logo to build up brand image which is familiar with children, as well as to offer the right standard and opportunity for food selection. The age level contains elementary graders from 8 to 13. The logo concept was focused on 'Safety', 'Certification, Guidance' and 'Health' in accordance with the vision of the Korea Food and Drug Administration (KFDA), "Safe food, good nutrition and healthy children". The logo name was proposed as "Best Food for Children", "Safety Food for Children" and "Children Good Food", which was decided by public subscription in the KFDA. The 36 tentative plans for a seal were proposed depending on names. We conducted a survey for the 12 logo samples, designed by the name of "Children Good Food", to use as the basic material for the development of logo to convey the meaning of children's food quality certification system effectively. This survey was conducted among 321 elementary graders and 331 parents of elementary graders. We selected the most favorite design through the survey and applied it for products practicality. It is expected that a steady policy may be possible to implement by applying the basis of the children's food project.

  • Five kinds of selective media, such as mannitol salt agar (MSA), Baird-Parker agar (BPA), Baird-Parker supplemented with rabbit plasma fibrinogen (BPA+RPF), CHROMagar Staphylococcus aureus (CSA), and Petrifilm Staph Express count system (Petrifilm), were compared to recommend the optimum selective media for isolation of Staphylococcus aureus from agricultural products. Seventy four target and non target bacteria were inoculated on five selective media to analyze sensitivity and specificity. In the recovery test of injured S. aureus cells, S. aureus was exposed to acid (1% lactic acid for 10 min), heat ($60^{\circ}C$ for 90s), and cold ($-20^{\circ}C$ for 1h) conditions. And artificially contaminated agricultural products (iceberg lettuce, green pepper, and cherry tomato) was enumerated on five selective media. The sensitivity of BPA+RPF, CSA, Petrifilm, MSA, and BPA were 100%, 100%, 100%, 90.5%, 90.5%, respectively. In addition, the specificity of BPA+RPF, CSA, MSA, BPA and Petrifilm were 100%, 100%, 84.6%, 75.0%, 67.3%, respectively. However, no difference among five selective media was observed in recovery on injured S. aureus cell and enumeration from agricultural products. This results suggest that BPA+RPF and CSA are the optimum media for detection of S. aureus from agricultural products.

  • As the number and weight of imported food are steadily increasing, safety management of imported food to prevent food safety accidents is becoming more important. The Ministry of Food and Drug Safety conducts on-site inspections of foreign food facilities before customs clearance as well as import inspection at the customs clearance stage. However, a data-based safety management plan for imported food is needed due to time, cost, and limited resources. In this study, we tried to increase the efficiency of the on-site inspection by preparing a machine learning prediction model that pre-selects the companies that are expected to fail before the on-site inspection. Basic information of 303,272 foreign food facilities and processing businesses collected in the Integrated Food Safety Information Network and 1,689 cases of on-site inspection information data collected from 2019 to April 2022 were collected. After preprocessing the data of foreign food facilities, only the data subject to on-site inspection were extracted using the foreign food facility_code. As a result, it consisted of a total of 1,689 data and 103 variables. For 103 variables, variables that were '0' were removed based on the Theil-U index, and after reducing by applying Multiple Correspondence Analysis, 49 characteristic variables were finally derived. We build eight different models and perform hyperparameter tuning through 5-fold cross validation. Then, the performance of the generated models are evaluated. The research purpose of selecting companies subject to on-site inspection is to maximize the recall, which is the probability of judging nonconforming companies as nonconforming. As a result of applying various algorithms of machine learning, the Random Forest model with the highest Recall_macro, AUROC, Average PR, F1-score, and Balanced Accuracy was evaluated as the best model. Finally, we apply Kernal SHAP (SHapley Additive exPlanations) to present the selection reason for nonconforming facilities of individual instances, and discuss applicability to the on-site inspection facility selection system. Based on the results of this study, it is expected that it will contribute to the efficient operation of limited resources such as manpower and budget by establishing an imported food management system through a data-based scientific risk management model.
