  • This study examined the status of current nutrition labelling and claims for the processed foods that were purchased in the supermarket. They were assessed in the aspects of frequency and content of nutrition labelling and claims. The results are summarized as follows; The percentage of products contain the nutrition labelling or claims of processed foods of investigation were 18.7% and 18.8% respectively. In the nutrition labelling method, the format separated by expression contents with 'only liability indication nutrient'or 'liability indication nutrients plus discretion indication nutrients' were 44.7% and 43.4% respectively. In the case of type and title, 'table' and 'nutrition composition'were used most frequently, 83.9% and 83.2% respectively. And in the case of expression unit, 'per 100 g or 100 ml'was higher (56.8%) than others. Nutrition claims were divided into 'nutrition content claim'and 'comparative claim', in the former the most claim was 'containing'and in the other'more or plus'used most frequently.'Nutrient function claim'was 13.4% and 'Implied nutrient claim'was 7.3% of all the claims. Results of the evaluation of current nutrition labeling system, nutrition labelling was less advanced and variable in content and format and also the information was not easy for consumers to understand and use them. To support achievement of the nutrition label, there must be program and initiatives for better understanding and communication and guidances on food labelling and nutrition for food manufactures.

  • 감은 종기, 염증질환, 부스럼 화상을 치료하고 고혈압을 예방하고 동맥경화에 효과가 있고 숙취해소에 효능이 있다고 알려져있다. 감과육에 알콜대사에 관여하는 acetaldehyde dehydrogenase(ALDH)의 활성을 촉진하는 물질이 존재하므로ALDH의 활성을 촉진하는 물질을 감의 계절별, 품종별 측정을 했고 또 감을 이용한 가공식품에 농도를 측정하였다. ALDH의 활성을 촉진하는 물질은 부유의 경우 11월에 수확한 과일에서 가장 높고 품종별로는 부유가 가장 높았고 갑주백목은 부유와 유사하였고 청도반시, 서촌조생의 순이었다. 가공식품은 감건조품, 곶감, 감즙은 대체로 ALDH의 활성을 촉진하는 물질의 활성이 높게 유지되나 감음료, 감식초와 같은 음료는 ALDH의 활성을 촉진하는 물질의 활성이 낮았다. 감 자체뿐만 아니라 감가공식품에서도 ALDH의 활성을 촉진하는 물질의 활성이 어느 정도 유지되므로 이를 이용한 숙취해소작용이 기대된다.

  • This study examined the nutrient components and measured the physicochemical properties of 23 Korean sweet potato cultivars. The proximate composition, free sugars, organic acids, and dietary fiber of sweet potato were analyzed and the water binding capacity, oil absorption and pasting characteristics were measured. The proximate composition was the highest in Happymi and was higher in colored sweet potato than in general sweet potato (p<0.05). The sucrose content was the highest among the free sugars in the general cultivars and yellow/orange colored cultivar. The major organic acids were oxalic acid, citric acid, malic acid, succinic acid, fumaric acid, and acetic acid. Oxalic acid and citric acid were high in the purple colored cultivars and malic acid was high in yellow/orange colored cultivars. Each total dietary fiber content of the general and colored cultivars was 7.51-13.94 and 13.04-16.97%, respectively, but there was no significant difference. The water binding capacity and oil absorption of Juhwangmi was high in all cultivars (p<0.05). The peak viscosity of sweet potato powder showed highest a significant difference of 12.50-1342 cP (p<0.05). The breakdown of Sincheonmi was 512, which was the highest value (p<0.05). The setback of Geonpungmi was significantly low, 6.0 (p<0.05).

  • The Hen's egg is widely used in many processed foods as an ingredient and is one of the most prevalent food allergens in children. To detect egg proteins in processed foods, we developed a competitive indirect enzyme-linked immunosorbent assay (ciELISA) using an anti-ovomucoid (OM) antibody, which was produced by immunization of rabbits with OM, the most heat-stable component of the egg proteins. The detection limit of this quantitative assay system was 30 ng/mL. Cross-reactivity of the anti-OM antibody toward OM, ovalbumin, skim milk, casein, whey protein isolate, and isolated soy protein was 100, 0.4, 0.2, 0.04, 0, and 0%, respectively. In the spike test of egg white powder in milk replacer, commercial sausage, and in-house sausage, the assay recoveries ($mean{\pm}SD$) were $129{\pm}13.7%$, $73.9{\pm}12.5%$, and $65.5{\pm}13.6%$, respectively. When egg white in a commercial crab meat analog and sausage was determined by ciELISA, the assay recovery was found to be 108% and 127%, respectively. The combined results of this study indicate that this novel ciELISA for OM detection could be applied for the quantification of hen's egg proteins in processed foods.

  • Nutrition labeling can provide information in order for people to select products suitable for their own health, and sodium content labeling for processed foods is important since sodium is one of the main causes of cardiac diseases. This study had carried out to propose the desirable sodium content labeling by conducting surveys on the awareness of sodium content in processed foods, understanding of sodium content labeling, and requirements for new sodium comparative claims. The survey period was from 12th of September, 2016 through the 24th, during which a self-administered questionnaire survey was given to 1,003 persons through demographic quota sampling by age and region. As a result of the survey, 66.0% of respondents assuring nutrition labeling answered they check sodium content labeling, whereas 83.2% were aware of excessive intake of sodium having a negative effect on health. Exactly 49.9% of respondents answered that the current system for nutrition labeling on processed foods does not help one to understand the content of sodium, whereas 72.9% answered they wanted to compare sodium contents with those of other products when buying or taking processed foods. As 92.5% cited the importance of sodium comparative claims made by processed foods, preparation of a new system for food labeling should be considered by which consumers can easily compare sodium contents with those of other similar products.

  • The purpose of this study was to monitor the current nutrition labeling practice on the packaging of the processed foods providing consumers with reliable nutrition information, which has been considered as a useful aid for food selection and a potent educational tool for nutrition in a daily life. The 2,214 processed foods purchased at the a wholesale market in July, 2003, were divided by food categories issued from the 2003 food codes and assessed in the terms of the nutrition composition labeling and nutrition claims. Nutrition composition labeling was found on 533 out of the 2,214 processed foods items. The findings of this study were as follows : Milk and dairy products had 66.4% of nutrition composition labeling, which was the largest percentage among the food categories. Tables format (71.3%) is the most widely used type of nutrition labeling. The title of nutrition composition labeling used the most widely was nutrition composition (71.3%). Nutrition composition included many different ways of expression, such as a table of nutrition composition, and indication of nutrition composition, etc. The expression unit of the nutrition composition labeling was use per 100g or 100mL (40.5%). The processed foods with nutrition claims were 18.0% (399 items). Nutrition claims were divided into two categories: nutrient content claims and nutrient comparative claims. The most frequently used nutrient content claims were contained (43.9%) and more or plus in the nutrient comparative claims (16.0%). Ca was the most popular item as a nutrition claim nutrient (33.6%).

  • This study was conducted to investigate the quality characteristics of peach jelly following the addition of various gelling agents (locust bean gum, carrageenan, xanthan gum). The various gelling agents were added to peach jelly at five levels (1.0, 1.5, 2.0, 2.5 and 3.0%), after which their effects on physicochemical properties, textural properties and sensory qualities were investigated. The total titratable acidity (TTA) of peach jelly was decreased with increases in gelling agent. Additionally, the sweetness and pH of peach jelly increased significantly as the amount of various gelling agents increased. Moreover, the lightness (L-value), redness (a-value) and yellowness (b-value) of peach jelly was decreased as the amount of gelling agent. Furthermore, the hardness, gumminess and chewiness of the peach jelly increased as the amount of gelling agent increased. Finally, the overall acceptance was higher for jelly containing 2.0% added gelling agent than for other samples. Based on the results of this study, it is recommended that mixed gelling agents be added to peach jelly at 2.0%.
