This study was performed to find out the correct recognition and stabilization of the food labeling system, and the dietary behavior of college students for processed food as well as their recognition of the food labeling system as observed according to their residence type. A questionnaire was composed with three divisions containing general items, the dietary behavior for processed food and the effectiveness of the nutrition labeling system. The data was analyzed by SPSS WIN 17.0 and the results are as follows; The findings showed differences according to residence type were the intake frequency of processed food, the ways of preservation and the reasons of returning or exchange of the purchased processed food. And there was no difference in the recognition of dietary behavior for processed food and food nutrition labeling system. For overall perception of the dietary behavior and the recognition of the food labeling system, the ratio of college students who considered selection standard related to health when purchasing processed food was low. And the ratio of those who checked the label for milk and dairy products or instant food which is concerned with decomposition was high. On the contrary, the ratio of checking was relatively low for beverages, noodles and cookies. Many answered that the reason for having checked the food label was to find out the safety of the food and that of having read the nutrition label was to control weight and to check the nutrition ingredients. In general, many answered positively for the recognition and the necessity of food labeling system, but the actual practice of selecting and managing processed food was poor.

The objective of this study was to compare the differences of opinion, purchasing behavior, and recognition of food labeling and nutrition labeling of frozen processed food between employees and non-employees in the frozen food industry. The results of this survey study showed that the group working in the frozen food industry had a positive opinion of frozen processed food compared to the non-employee group who was not working in the food industry. The main reason for the positive opinion of frozen processed food was because it was convenient and easy to prepare while the main concern with consuming frozen processed food was that it was bad for one's health. The most popular menu was western style. Sixty one percent of employees in the frozen food industry preferred the microwave-cooking method, while only 37.9% of non-employees preferred the microwave-cooking method followed by cooking in boiling water (27.6%). There was a significant (p<0.001) difference in the preference of cooking method between these two groups. Most of the respondents considered 'taste' as the most important factor and 32.9% of the respondents selected 'sanitation/health' as the most serious concern for the consumption of frozen processed food. Both groups checked the food & nutrition label to verify the expiration date and the presence of food additives. The non-employee group recognized the need for nutritional information on total calorie, carbohydrate, protein, fat, saturated fat, cholesterol, minerals, vitamins, sodium, and fiber on the nutrition label of frozen processed food.

The issue of health risks from consuming unhealthy product is an important issue that is happening right now. Both developed and developing countries are already aware of the need for attention to the health-risk products. One tool that is believed to be able to change the consumption behavior of the health-risk products is the use of warning label on product packaging. As a persuasive act, both visual and textual warning label are believed to be able to change people's consumption behavior. In addition to the labels that contain health hazards, this research also uses social consequence contents. The main targets of such unhealthy product marketing are children and adolescents. Correspondingly, this study targets the age groups of kids and tweens. The method used in this research is experiment, involving 180 participants from two age groups namely kids and tweens. As a result, the study found that the influence of warning label on the age of tweens is greater in the age of the children. Meanwhile, the use of visual and textual warning label using social consequences contents, proved to be effective at the age of tweens. These results are useful for enrich social marketing subjects, especially within warning label research.

This study was designed to examine nutrition label use, self-efficacy, snacking and eating behaviors of middle school students, and to investigate if these characteristics were different by nutrition label use. A cross-sectional survey was conducted to 348 middle school students in Kyunggi, Korea. About a third of subjects read nutrition labels when they purchased snacks/packaged foods. Most nutrition label users were interested in reading information on calories, fat and trans-fat. Self-efficacy of eating/selecting snacks or general nutrition behavior was moderate (mean score: 44.4 out of 60), with significantly higher score in nutrition label users compared to nonusers (p < 0.001). Nutrition label users felt more confident in 9 items out of 15 items of self-efficacy, such as "taking fruits instead of cookies/candy for snack" (p < 0.001), "choosing milk instead of soft drink" (p < 0.01), "not having snacks after dinner" and "avoiding processed foods for snacks" (p < 0.05). Subjects had snacks 1.3 times a day, and nutrition label nonusers consumed snacks more frequently than the counterparts (p < 0.01). About 55% of nutrition label users and 64.7% of nonusers mainly purchased snacks for themselves (p < 0.05). Commonly purchased snacks by adolescents were ice cream, cookies/chips, breads and ramen. Major considerations in purchasing snacks were taste (46.9%) and price (34.6%). In selecting snacks, the influence of friends and parents was greater than the other sources. Based on eating frequency of snacks, nutrition label users were more likely to consume healthy snacks, such as fruit juices, vegetables, milk, yogurt, and potato/sweet potato than nonusers (p < 0.05). Eating behaviors measured by 15 items scored 33.6 out of 45. Nutrition label users showed better eating behaviors, such as "eating meals slowly", "eating foods cooked with plant oil", and "eating out less frequently" (p < 0.05). Study results showed that majority of adolescents did not read nutrition labels, selected snacks for themselves and had somewhat unhealthy foods for snacks. This study also showed the differences in self-efficacy, snacking and eating behaviors between nutrition label users and nonusers. In nutrition education, it is necessary to stress the importance and skills for reading nutrition labels. It is also needed to help adolescents to select healthy snacks and have desirable eating behaviors, as well as increasing self-efficacy.

This research was conducted to evaluate consumers' understanding and preference for shelf life and ingredient listings in food label by survey using a questionnaire. The questionnaires were collected from female adult consumers residing in Seoul, Kyonggi, Choongnam and Chungbuk areas. Most of the consumers showed good understanding for shelf life and ingredient listings in food label. They had no particular preference for the types of shelf life labelling. They preferred listing all ingredients completely with amounts, but differentiated from food additives. They wanted to get more information about shelf life and ingredient listings in food label that is mainly associated with food safety They showed more preference for labelling the shelf life in the information panel with a storage condition. Most of them chose the ingredient list format in which each ingredient was written in one row in bold characters with percentage labelling.

Clean labeling is emerging as an important issue in the food industry, particularly for meat products that contain many food additives. Among synthetic additives, nitrite is the most important additive in the meat processing industry and is related to the development of cured color and flavor, inhibition of oxidation, and control of microbial growth in processed meat products. As an alternative to synthetic nitrite, preconverted nitrite from natural microorganisms has been investigated, and the applications of pre-converted nitrite have been reported. Natural nitrate sources mainly include fruits and vegetables with high nitrate content. Celery juice or powder form have been used widely in various studies. Many types of commercial starter cultures have been developed. S. carnosus is used as a critical nitrate reducing microorganism and lactic acid bacteria or other Staphylococcus species also were used. Pre-converted nitrite has also been compared with synthetic nitrite and studies have been aimed at improving utilization by exploiting the strengths (positive consumer attitude and decreased residual nitrite content) and limiting the weaknesses (remained carcinogenic risk) of pre-converted nitrite. Moreover, as concerns regarding the use of synthetic nitrites increased, research was conducted to meet consumer demands for the use of natural nitrite from raw materials. In this report, we review and discuss various studies in which synthetic nitrite was replaced with natural materials and evaluate pre-converted nitrite technology as a natural curing approach from a clean label perspective in the manufacturing of processed meat products.

The purpose of this study is to help operate and manage the new food period, use-by-date by investigating consumer perception of various food periods, and change of purchasing and consumption period by food period label. Compared to the purchasing period of sell-by-date, the ratio of the purchasing period also increased as the proposed period of the use-by-date and the best before date increased. The use-by-date should be set at least 15 days to reduce food waste as the consumption period is the same as the sell-by-date. This can be said to have an anchoring effect that changes the purchasing and consumption period of consumers depending on how much the food period is indicated even for the same product. In order to reduce consumer confusion and food waste due to sell-by-date, it is considered to label the sell-by-date and use-by-date or use-by-date and best before date in parallel.

We investigated the effects of different phosphate replacements on the quality of ground pork products cured with sodium nitrite or radish powder to determine their potential for achieving clean-label pork products. The experimental design was a 2×5 factorial design. For this purpose, the ground meat mixture was assigned into two groups, depending on nitrite source. Each group was mixed with 0.01% sodium nitrite or 0.4% radish powder together with 0.04% starter culture, and then processed depending on phosphate replacement [with or without 0.5% sodium tripolyphosphate; STPP (+), STPP (-), 0.5% oyster shell calcium (OSC), 0.5% citrus fiber (CF), or 0.5% dried plum powder (DPP)]. All samples were cooked, cooled, and stored until analysis within two days. The nitrite source had no effect on all dependent variables of ground pork products. However, in phosphate replacement treatments, the STPP (+) and OSC treatments had a higher cooking yield than the STPP (-), CF, or DPP treatments. OSC treatment was more effective for lowering total fluid separation compared to STPP (-), CF, or DPP treatments, but had a higher percentage than STPP (+). The STPP (+) treatment did not differ from the OSC or CF treatments for CIE L^* and CIE a^*. Moreover, no differences were observed in nitrosyl hemochrome content, lipid oxidation, hardness, gumminess, and chewiness between the OSC and STPP (+) treatments. In conclusion, among the phosphate replacements, OSC addition was the most suitable to provide clean-label pork products cured with radish powder as a synthetic nitrite replacer.

This study evaluated the satisfaction and healthy eating index of nutrition-plus program providing nutritional supplements to pregnancy, lactating women, infant and children. This program was carried out at Public Healthcare Center, Seodaemun-gu in Seoul from February 2014 to June 2014. The subject selected among applicants for low income family financing of the government included 159 subjects. There was no statistically significant difference for degree of satisfaction with supplementary food by age, but the degree tends to get higher at lower age. Degree of satisfaction with supplementary food by the duration for participation was shown higher as the duration gets longer. For questions of 'Do you check nutrition label?' and 'Do you preserve food as described at food label?' in healthy eating index evaluation, the scores appeared higher at younger age group as they check the nutrition label more. Also as the duration for participation gets longer, the scores appeared higher which can be interpreted as effect of nutrition education from Nutrition-Plus. Frequency of having breakfast gets lower at higher age of subjects. And it gets higher as the duration for participation gets longer even though that there's no difference between '3 to 4 months' and '5 to 8 months' of the duration of participation. For evaluation of food security in recent 1 year, 86.8% of subjects responded 'Food sufficiency' and 'Enough but not always the kinds of food we want', and there is no difference by age and the duration of participation. As a result of this research, it is shown that the subjects of nutrition support project are relatively satisfied with the support. And healthy eating index gets improved as the duration of participation gets longer which can be considered as effect of nutrition education. It seems to be necessary to keep nutrition education as well as food support so to perform food life education on appropriate purchase and consumption of food.

The objectives of this study were to determine the preferences and consideration factors for selecting processed foods, in middle school students as well as their perceptions on food and nutrition labeling student. Middle school students in the Seoul area were surveyed from October to November, 2006. The results are summarized as follows: the preferred processed foods included 'drinks' (3.85), 'noodles' (3.81), 'biscuits and bread' (3.80), 'milk and dairy products' (3.71), and 'meat and meat products' (3.60). The most important consideration factors in selecting processed foods were 'expiration date' (4.45), 'taste' (4.34), and 'price' (4.08). The two main reasons for eating processed foods were 'delicious' (43.1%) and 'convenient' (33.9%). Food labels were identified 'sometimes' (34.5%), 'rarely' (31.2%), and 'almost never' (18.6%). The primary reason for examining a food label was 'to confirm the expiration date' (52.6%). The main reason for not reviewing a food's label was 'habitual purchase' (57.8%). Nutrition labels were identified 'rarely' (33.4%), 'almost never' (24.7%), and 'sometimes' (23.5%). The reasons for examining nutrition labels included 'to confirm a high proportion of nutritive substances' (26.5%), 'boredom' (24.2%), 'for weight control' (23.5%), and 'to improve health' (18.1%). The main reason for not examining a food's nutrition label was 'not interested' (56.5%).
