As a result of analysis on situations of environment-friendly school meals, it was obtained that student's parents were interested in food safety and the importance of sanitary supervision. Many parents responded that environment-friendly school meals increased the health and eating habits of their children. The higher and higher educated parents responded that environment-friendly school meals effected on the children's health positively. Also, the higher educated parents responded that environment-friendly school meals effected on the children's eating habits positively. After the environment-friendly school meals, the item increase to purchase was vegetables by 25% of the consumers who purchase environment-friendly agri-products. The second and third increasing items were respectively fruits and rice. When environment-friendly agri-products were consumpted and influenced positively through school meals, the consumption of environment-friendly agricultural products will be increased. The expansion of environment-friendly school lunch program cannot bring the consumption expansion of environment-friendly agri-products immediately. However, when the persistent promotion and student's parents confidence on environment-friendly agri-products were accumulated and experienced positive effects through school meals, it will give a positive effect on the consumption of environment-friendly agr-products.

The objective of this study was to investigate the effect of dietary education on undergraduate student's health, environment, and consideration. A total of 54 participants were recruited from an undergraduate student in Seoul. We conductive quantitative analysis of a structured questionnaire and qualitative analysis of interviews recorded by photovoice. There are significant differences among knowledge, dietary attitude, and food behavior in the field of health (p<0.001). In the field of health, photovoice data were categorized as 'health care practice', 'Korean dietary lifestyles', or 'awareness of importance of health' (p<0.001). In the field of environment, photovoice data were categorized as 'environment-friendly dietary lifestyle' and 'environmental contamination minimization'(p<0.001). In the field of consideration, photovoice data were categorized as 'gratitude for others', 'joy of cooking'or 'eating meals together'(p<0.01). In conclusion, we found that dietary education about health, environment, and consideration may affect healthy dietary lifestyle among undergraduate students. Our findings may warrant further studies to develop significantly effective dietary education for undergraduate students.

Objective: The aim of the present study was to investigate the effect of dietary zinc supplementation of Friesian cows on chemical-nutritional and aromatic properties of Caciocavallo cheese after 7 days (C₇) and 120 days (C₁₂₀) of ripening. Methods: Twenty eight Friesian cows, balanced for parity, milk production and days in milk, were randomly assigned to 2 groups. The control group (CG) was fed with a conventional complete diet, while the experimental group (zinc group, ZG) received a daily zinc supplementation of 60 mg for kg of dry complete feed. During the experimental period, the milk yield was monitored and samples of milk and caciocavallo cheese were collected and analyzed for chemical-nutritional composition and aromatic profile. Results: The enrichment of dairy cows diet with zinc, did not influence milk yield and composition, however a marked reduction of somatic cell count was evidenced. Both in milk and cheese the ZG samples were characterized by a lower concentration of satured fatty acids and an increase in oleic, vaccenic and rumenic acids. The aromatic profile of dairy products was also positively affected by dietary zinc intake, with an increase in concentration of carboxylic acids, esters and lactones. Conclusion: The present results suggest a positive role of dietary zinc intake in improving the quality of bovine milk and related cheese, in particular for the increase in concentration of bioactive fatty acids such as rumenic acid. The changes evidenced in cheese through the analysis of the volatile profile, would be consistent with the development of interesting organoleptic properties, although further evaluations should be performed to confirm the consumer acceptability of these changes.

To assess accurate methods for measuring sulfur dioxide residue in pickles, the acid distillation HPLC-UV method and Monnier Willams modified method were examined. By the acid distillation HPLC-UV method, sulfites released from pickles by acid distillation were absorbed in 1% triethanolamine solution and detected as sulfite ion by HPLC with UV monitoring at 240nm. An anion exchange column was employed with 1.8mM $Ma_2CO_3-1.7mM\;NaHCO_3$ solution as a mobile phase, $84.0{\sim}91.7%$ of sulfite added to pickled radish were recovered. Total sulfite levels from 48 kinds of pickles analyzed by acid distillation HPLC-UV was compared with those analyzed by the Monnier Williams modified method. The Monnier Williams modified method showed higher levels of sulfur dioxide than the acid distillation HPLC-UV method due to the presence of volatile acids in pickles. The concentration of sulfur dioxide was in the range of $N.D{\sim}173.05ppm$ in pickled radish and over 30ppm of sulfur dioxide from 3 samples by the acid distillation-HPLC-UV method.

Objective: The aim of this work was the characterization of the qualitative aspects of meat obtained from Teramana goats, an Italian indigenous breed of the Abruzzo region. Specifically, the study included a comparison with meat samples deriving from Saanen goat kids reared in the same environment and applying the same feeding protocol. Methods: Upon reaching about 7 months of age the animals were slaughtered and samples of muscle tissue were collected to be analyzed. Specifically, meat samples were subjected to evaluations of the physical parameters, including color and the meat ability to retain water, in addition to chemical evaluations that were focused to the determination of the total lipids amount, fatty acids composition, lipid oxidation, and volatile profile. Results: The meat samples obtained from the indigenous breed showed a less intense reddish color and no significant variations for the muscle tissue tendency to retain water, both regarding fresh and cooked meat. Several differences were instead observed in the fatty acid profile. The Teramana samples were richer in saturated fatty acids (p<0.01) and interestingly showed higher concentrations of rumenic acid (p<0.05), a conjugate of linoleic acid that has been associated with important health benefits for the consumers. Another important finding for these meat samples was the marked resistance to oxidative events, as evidenced by the thiobarbituric acid reactive substances-test (p<0.05) and by the characterization of the volatile profile that highlighted a strong reduction in the relative percentage of hexanal (p<0.05), commonly associated to lipid oxidation and the development of unpleasant aromatic notes. Conclusion: The collected data, therefore appeared useful for the valorization of the food product derived from the Teramana goat, although no sensory information has been collected to define the degree of acceptability by the consumers.

The environment-friendly agricultural product market receives consumers' great interests despite relatively few studies focused on consumers' decision making process of the environment-friendly agricultural products. This paper examines what factors influence on consumers' attitude and buying behavior on the environment-friendly agricultural product. In order to find the relative importance of each factor's influence, this study adopts multiple regression method based on the survey results of 500 people with the systematic random sampling. The results showed that consumers' favorable attitude towards the environment-friendly agricultural product were influenced by taste, freshness, food safety, and positive attitudes toward the environment-friendly agricultural product promotion. In addition, consumers' purchase intention was influenced by taste, food safety, environmental concern, and the promotion. Respondents recommend the environment-friendly agricultural product when they believe that the environment-friendly agricultural product had the values of taste, environmental concern, and promotion. Women are more active in buying and recommending the environment-friendly agricultural product; however, the price was not the statistically meaning factor. This study provides empirical data that was used for marketing and increasing the sales of the environment-friendly agricultural product. Future research was advised to examine more thoroughly on the relationships between the promotion efforts and purchase intention and the occasions when the price becomes the issue in the buying decision of the environment-friendly agricultural product.

Whole wheat flour is produced by grinding wheat grains and blending each milling fraction such as wheat bran and white flour with no specific standard for the proportions. An exploration on classifying and utilizing Korean whole wheat flour is required to increase the practical use of many different types of Korean wheat flour products. This study aimed to examine factors for categorization and processability of Korean whole wheat flour by investigating quality characteristics and bread-making properties of Korean hard wheat flour samples produced with different levels of wheat bran (0% as control, 5%, 10%, 15%, 20%, and whole grain wheat flour). The ash content of flour samples was divided into six gradational categories, which could be suggested as classification criteria for Korean whole wheat flour. The main parameters of dough and gelatinization properties of the flour samples exhibited downtrends, but nutritional constituents demonstrated uptrends with increasing bran addition level. The bread specific volume, hardness, chewiness, and brittleness of bread had strong correlations with dough stability and pasting parameters, which could be presented as significant factors for predicting bread-making properties of Korean whole wheat flour.

This study analyze factors influencing the dietary life of Korean women. This study analyzed 653 women aged 19 (and over) in Korea using materials developed by Social Sciences Korea Food Sustainability Study Group in 2015. As a result, in dietary life characteristics, females with higher education in their 40s and 50s and with a high income level, married women, and women thinking are subjectively healthy and show a statistically significant difference compared to other groups. Next, a correlation analysis is conducted to examine the relationship between independent variables and dietary life. The results showed a positive relationship with all variables, and a high correlation in the sales recognition of homegrown products (r=.384), the recognition of a food environment (r=.349), the recognition of food welfare (r=.325), and the recognition of food safety (r=.322). Factors that influence dietary life are extracted and the causal relationship is verified through multiple regression analysis of which the dependent variable is dietary life. In a regression model of dietary life, the researcher finds the trend that explanation power increases by models that the variable group is added in an individual model ($R^2$ is changed from .090 to .215 and from .250 to .273). Subsequently, age, level of education, recognition about value of organic agricultural product, recognition about the sales of homegrown products, recognition of food environment, recognition of food safety, and recognition of food insecurity are factors that influence the dietary life of women.
