본 연구는 소비자 니즈의 변화에 따른 식품컨셉의 변형으로 인한 일본의 식품유통시스템의 발전과정을 살펴보는 것을 연구의 목적으로 한다. 본 논문에서는 식품컨셉으로서 일반적으로 가공식품과 비가공식품으로 분류되었던 식품컨셉을 확장시켜 비가공적 가공식품과 가공적 비가공식품의 개념을 소개하고, 그에 따른 일본식품유통시스템의 물류, 도매, 소매상에서의 혁신적 관리 및 발전과정을 살펴본다. 일본 식품유통시스템의 변화에 근본적인 원인을 제공한 요인으로서 소비자 니즈와 인식의 변화를 들 수 있으며, 일본 식품유통시스템의 개념정립 및 현황분석과 함께 일본 식품유통시스템의 실제적 변화로서 온도대별 물류혁신, PB상품개발, 체인시스템의 다양화 등을 살펴보기로 한다. 이와 같은 일본소비자의 특성, 식품유통시스템의 발전상황 및 사례를 연구함으로써 한국식품유통시스템의 발전과정과 비교분석이 가능하며 나아가 합리적인 식품유통시스템으로의 방향제시가 가능하다고 사료된다.

Antioxidant films are one active packaging technology that can extend food shelf-life through preventing lipid oxidation, stabilizing color, maintaining sensory properties and delaying microbial growth in foods. Because raw, fresh and minimal processed foods are more perishable during storage or under display conditions than further processed foods, they rapidly lose their original quality. Foods are susceptible to physical, chemical, and biochemical hazards to which packaging films can be effective barriers. Although films incorporated natural (tocopherols, flavonoids and phenolic acids) or synthetic antioxidants (BHT, BHA, TBHQ, propyl gallate) have been extensively tested to improve quality and safety of various foods, food applications require addressing issues such as physical properties, chemical action, cost, and legal approval. Increased interest in natural antioxidants as substitutes for synthetic antioxidants has triggered research on use of the new natural antioxidants in films and coatings. Use of new components (phytochemicals) as film additives can improve food quality and human health. The biosynthesis of plant phenolics can potentially be optimized by active coatings on harvested fruits and vegetables. These coatings can trigger the plants natural proline-linked pentose phosphate pathway to increase the phenolic contents and maintain overall plant tissue quality. This alternate metabolic pathway has been proposed by Dr. K. Shetty and is supported by numerous studies. A new generation of active food films will not only preserve the food, but increase food's nutritional quality by optimizing raw food biochemical production of phytochemicals.

The purpose of this study was to examine the food labelling system and its regulations based on Food Hygine Law in Korea and to compare them with those of USA and JAPAN. This study was carried out to suggest desirable direction for improvement of food labelling system in Korea by reviewing literatures and regulations related to the subject of this study. The results are as follows: 1. The indication of shelf-life in Korean lavelling system appeared ineffective from the point of view of consumer protection and resource preservation compared with dual system of indicating shelf-life in USA and Japan. 2. The standard of labelling general food in Korea does not give sufficient nutritive information to the consumers, compared with that in USA and Japan. 3. Only five ingredients including additives are to be listed on the food label in Korea whereas all the ingredients and additives are in the USA and Japan. 4. The way of Listing food additives on food label is neither specifically required nor standardized in Korea and, food additives are classified into only 7 groups in Korea while 18 in the USA. Based on the above results of literature review, the followings are suggested to improve food labelling system in Korea. 1. Indication of shelf-life should have dual system, in which perishable food should not be permitted to be sold after its shelf-life while the processed food or dried food to be preserved for a long time should be indicated with more or less flexible term about shelf-life. 2. Standard of labelling general food should include calorie, fat, protein, and the content of major vitamins and minerals. 3. All ingredients and their contents, including food additives should be listed on the food labels. 4. The standard of indication of food additives in Korea should include the name, usage and content of all additives used in foods.

Recently, consumers have gained an interest in natural and minimally processed foods, inciting the food industry to consider using of natural products as preservatives. Strawberries are a widely consumed fruit but are also highly perishable. Therefore, in this study, the physicochemical properties of strawberries (Fragaria×ananassa) were evaluated after a 12-h treatment with lemon essential oil (Citrus×limon) or cinnamon essential oil (Cinnamomum cassia) vapor during storage at 22℃ for 4 days in an accelerated shelf-life study and 4℃ for 18 days in a validation study. Weight loss was blunted in fruit treated with oil vapor during the first days of storage (p<0.05). Lemon essential oil delayed fruit darkening (p<0.05) but reduced the firmness of strawberries (p<0.05). Strawberries treated with cinnamon essential oil had a higher concentration of reducing sugars (p<0.05), and a decrease of 16.7% visible decay, although the difference was insignificant. Oil vapor treatment did not alter the pH, organic acid content, or soluble solid content during storage compared to the control. Since lemon and cinnamon essential oils have well-documented antimicrobial properties, they may be suitable for the natural preservation of fruit. This study provides new information on using essential oil vapor treatment to preserve fruits, and potentially decrease fruit loss and waste.
