  • Detection of specific compounds influencing food flavor quality is not easy. Electronic nose, comprised of electronic chemical sensors with partial specificity and appropriate pattern recognition system, is capable of recognizing simple and complex volatiles. It provides fast analysis with simple and straightforward results and is best suited for quality control and process monitoring of flavor in food industry. This review examines application of electronic nose in food analysis with brief explanation of its principle. Characteristics of different sensors and sensor drift. and solutions to related problems are reviewed. Applications of electronic nose in food industry include monitoring of fermentation process and lipid oxidation, prediction of shelf life, identification of irradiated volatile compounds, discrimination of food material origin, and quality control of food and processing by principal component analysis and neural network analysis. Electronic nose could be useful for quality control in food industry when correlating analytical instrumental data with sensory evaluation results.

  • There are more than 2000 minerals on earth, and it has been implemented in various fields such as environment, architecture, livestock, chemistry, pharmaceuticals. Clay minerals are considered that they can change the physical and chemical properties through the adsorption and release of metal ions. Although domestic deposit of non-metallic mineral resources is approximately ninety-six billion tons, its application is limited and has hardly been used in high value-added industries involved in medicine, medical supplies, and functional food materials. Bentonite and zeolite are already used for cosmetic purposes and also used in living goods and packing materials. However, direct application to the food industry is relatively very rare. Since records regarding the intake of minerals for foods and medicines are found in the old literatures, the utilization of non-metallic minerals as food materials appears to be highly profitable. According to the trends in patent research for food and mineral resources, the company plays a main role for the development of the food containing non-metallic minerals in USA, and the trends confirms that this industry is emerging. Here, we provided the information about domestic and foreign patent trend for food industries involved in mineral resources and the application of mineral resources in the food industries. We also covered the domestic regulation regarding usage of mineral resources in food, and proposed domestic application plan for food production using mineral resources in the future.

  • We analyzed the HACCP prerequisite of National Veterinary Research and Quarantine Service (NVRQS) and the Food Establishment Inspection Report of US Food and Drug Administration (FDA) to recommend contents and ranges to be complemented and used for preparation of guidelines for more effective application of HACCP prerequisites. We used the HACCP inspection reports implemented by Korea Livestock Products HACCP Accreditation Service from 2007 to 2009, FDA Food Code 2009 Guide 3-B Instructions for Marking the Food Establishment Inspection Report, and Retail Food Establishment Sanitation Requirements of 410 Indiana Administrative Code. Major non-compliance items were open doors and windows, insanitary cleaning of in-use utensil, inadequate record of warehousing, and improper storage, transportation, and labelling. Hot water supply, personal hygiene, and regular product testing were additional week points which should be more strongly controlled by detailed operating guidelines. Also, current prerequisite items were required revision into more precise contents to enhanced the effective evaluation and practical application in meat markets.

  • As a result of analyzing the domestic and foreign HACCP systems, advanced countries mandated HACCP system on all foods to strengthen food safety management and USA, EU and China do not apply small-scale HACCP system. Looking at the cases of food safety accidents in Korea and the non-compliance rate of HACCP certification evaluation by size, the accident rate of companies without HACCP certification was 31.2% higher than that of companies with HACCP certification. The nonconformity rate of food inspection standards was analyzed to be 89.0% higher than that of HACCP certification companies. Based on the international trend of food safety management and the frequency of food safety accidents, it is proposed to gradually expand the mandatory application of HACCP system in Korea to all foods, and to change the small-scale HACCP standard from less than 500 million Korean won or 21 employees to less than 500 million Korean won.

  • Concerns on environmental waste problems caused by non-biodegradable petrochemical-based plastic packaging materials as well as consumer's demand for high quality food products has caused an increasing interest in developing biodegradable packaging materials using annually renewable natural biopolymers such as polysaccharides and proteins. However, inherent shortcomings of natural polymer-based packaging materials such as low mechanical properties and low water resistance are causing a major limitation for their industrial use. By the way, recent advent of nanocomposite technology rekindled interests on the use of natural biopolymers in the food packaging application. Polymer nanocomposites, especially natural biopolymer-layered silicate nanocomposites, exhibit markedly improved packaging properties due to their nanometer size dispersion. These improvements include increased mechanical strength, decreased gas permeability, and increased water resistance. Additionally, biologically active ingredients can be added to impart the desired functional properties to the resulting packaging materials. Consequently, natural biopolymer-based nanocomposite packaging materials with bio-functional properties have huge potential for application in the active food packaging industry. In this review, recent advances in the preparation and characterization of natural biopolymer-based nanocomposite films, and their potential use in food packaging applications are addressed.
