This study aimed to enhance the applications of dates as a food material that can be utilized and stored easily by improving the inefficient process of the traditional cooking procedure. To this end, this study investigated the physico-chemical and nutritional properties of jujube pulp powder, and compared the traditional and newly developed methods of making yakbap, yakpyon, and jujube porridge. According to the analysis of physical and chemical properties, the jujube pulp powder contained 5.4% moisture, 2.6% crude ash, 6.6% crude protein, 0.35% crude fat, and 4.7% crude fiber. The water activity was 0.95% in jujube pulp while it was 0.24% in jujube pulp powder. In addition, the jujube pulp powder had a total sugar content of 70.4% and reducing sugar content of 6.3%. The vitamin C was content was estimated to be 68.5 mg/100 g in the jujube pulp powder and the jujube pulp contained 6.2 g/100 g of dietary fiber. Major minerals were K, Mg, and Ca. After appointing jujube pulp powder (new method) to a test group and jujube pulp (traditional method) to a control group, the sensory evaluation and acceptance testing were conducted for yakbap, yakpyon, and jujube porridge. As a result, there was no significant difference in any sensory factors tested (p<0.05). It was found that making and storing jujube pulp powder by drying jujube pulp is a useful way of utilizing jujube because Yakbab, Yakpyun and jujube porridge were found to have a relatively good appearance, color, flavor, taste, texture and overall acceptance.

The changes of resistant starch (RS) contents of cooked rice with soybean and coconut oils under different storage conditions were investigated and RS contents were compared between the rice and cooker types. The japonica (Hopyeong) and the indica (Thailand) type rice were cooked (washed rice: water = 100: 130) using an electric cooker and a saucepan. The coconut oil and soybean oil (3%, based on rice, w/w) were added into cooking water before heating. The RS contents of freeze-dried cooked rice powders (newly-cooked rice, stored for 12 h in the refrigerator, microwave heating after storage for 12 h in the refrigerator) were measured by the AOAC method. The RS contents of cooked rice using a saucepan were higher than those using an electric cooker. The indica type cooked rice had a higher RS content than the japonica type cooked rice, regardless of storage conditions. However, addition of oil before cooking rice resulted in increased RS content on storage in the refrigerator. The highest RS content of the cooked indica type rice with soybean oil (
) that was stored for 12 h in the refrigerator was analyzed. The results suggested that the cooked rice formed retrograded (RS3) and amylose-lipid complex (RS5) type RS; furthermore, the RS content is affected by storage conditions, rice, cooker and oil types.

In this study, we aimed to develop functional vinegar with different levels of black garlic through two stages of fermentation. Black garlic vinegars were prepared from black garlic and water (w/w) mixed with 1:2 (BG3), 1:5 (BG6), 1:9 (BG9) and 1:11 (BG12), and adding the sugar by adjusting the soluble solids content to
. The alcohol content of black garlic vinegar was 5.2-5.5% after 7 days of alcohol fermentation at
. Acetic acid fermented was at
for 25 days and samples were taken at 3, 6, 9, 12, 15, 20 and 25 days. The pH of black garlic vinegar was not significantly different among the samples, but acidity was increased during fermentation. Total polyphenol contents showed irregular changes with the fermentation periods and were higher by black garlic content. At 25 days fermentation, total polyphenol contents were 18.96-56.56 mg/100 mL. Acetic acid content of black garlic vinegars was higher than other organic acids. S-allyl cysteine (SAC) contents of BG3 and BG6 were 13.03-14.54 and 1.69-2.20 mg/L, respectively. However SAC was not detected in BG9 and BG12. In 25 days fermented black garlic vinegar, the major mineral was K with a content ratio of 61-68% of total minerals. The DPPH and ABTS radical scavenging activity of 25 days fermented black garlic vinegar were stronger at higher black garlic content.

We conducted comparative analysis on the quality characteristics five different classes of the Songgi (Pine inner bark) Garaetteok with different pine inner bark 0%, 1%, 2%, 3%, and 4%, respectively. The experiment results show that color values of the Songgi Garaetteok pine inner bark powder, the L value highest in control group 72.91 while a value was highest in 4% group. As a result of measurements for three days, the moist content for control group and 1% group 48.89 and 51.65, respectively two hours production. On day 1, the moist content of all samples peaked. Harness peaked in control group 954.13, followed by 4% group. The DPPH radical scavenging ability of pine inner bark powder and the Songgi Garaetteok containing 4% pine inner bark highest at 11.61% and 7.14%, respectively. In evaluating antibiosis, the Songgi Garaetteok containing 4% pine inner bark the highest level of antibacterial activity. In sensory evaluation, the Songgi Garaetteok containing 2% pine inner bark received the highest score color, flavor, texture, taste and overall preference. The experiment that the Songgi Garaetteok pine inner bark powder has better antioxidative effect regular Songgi Garaetteok. Therefore, the Songgi Garaetteok 2% pine inner bark powder the most desirable of the Songgi Garaetteok containing pine inner bark.

DOI : 10.9724/kfcs.2016.32.1.50
In this study, kim (dried laver) bugak ("KB"), Aster yomena bugak ("SB"), and namul (vegetables)-kim bugak (combination of Aster yomena and kim) ("NB") were prepared and their quality characteristics were investigated. NB was made by slicing Aster yomena, seasoning it with perilla seeds, attaching it to kim and applying glutinous rice paste, followed by freeze-drying. SB had a higher oil absorption rate than KB, reflecting the high oil absorption rate of namul (here, Aster yomena). DPPH radical scavenging activity was highest for SB; whereas, NB had higher DPPH radical scavenging activity than KB, indicative of the higher antioxidant capacity of namul, as compared to kim. With longer storage period, moisture content tended to be increased, while maximum load, yield stress and hardness tended to be decreased. Overall preference was in the order of NB>KB>SB, without statistical significance. Acid value and peroxide value of NB, stored at
for 40 days, tended to be increased gradually but did not meet the criteria for rancidity. Therefore, NB could be stored at
for > 40 days. Furthermore, it would be possible to make functional bugak using a variety of namul, as well as Aster yomena.

The effects of reducing pork hind legs concentrations from 80% to 60% and replacing the pork head meat with up to 20% pork head meat were investigated based on chemical composition, cooking characteristics, physicochemical properties, shear force, and sensory characteristics of hamburger patties. The increasing the pork head levels from 0% to 20% increased the protein content, pH, reduction in diameter, reduction in thickness, and shear force of hamburger patties, but decreased the moisture content, lightness, redness, yellowness, cooking yield, and water holding capacity of hamburger patties. The fat and ash contents of the hamburger patties with different amounts of pork hind legs and pork head showed no significantly different sensory characteristics from the control and all the treatments (p>0.05). The hamburger patties with increasing pork head levels had lower color, flavor, juiciness, and overall acceptability scores, but the overall acceptability of control showed similar trends to T1 and T2. Therefore, replacing pork hind legs with pork head meat in the formulation was successfully similar to control hamburger patties, with best results obtainedon replacing up to 10% pork head meat.

The purpose of this study was to analyze meal management behaviors for Korea dietary acculturation among multicultural families in Korea. The study compared differences in meal management behaviors among 90 multicultural families. Results of the study were as follows: cultural adaptation to Korea got higher with increasing age; marriage immigrants with longer marriage duration and with children showed higher cultural adaptation to Korea. Regarding food value of marriage immigrant women, 'eating favorite food' was the highest in the 20s, while 'satisfaction with Korean dietary lifestyle' was high in Chinese and in those with longer residency. Most of them replied 'myself' for the meal manager of their multicultural family. When surveyed on major difficulties in Korean meal management, existence of children showed significant difference for 'cooking', and period of residency and existence of children made significant difference for 'taste'. In conclusion, meal management behavior of multicultural families was influenced by socioeconomic factors. Further research is needed for more quantitative analysis and understanding of the effect of dietary patterns on nutritional status and quality of life in multicultural families.

DOI : 10.9724/kfcs.2016.32.1.114
This study was conducted in order to evaluate the current status of management of students affected by food allergy and provide basic data necessary to school foodservice. A survey was conducted on 300 nutrition teachers (dietitians). For food allergy management, 79.3% of participants regularly checked on students with food allergy. The rate of providing allergy-free or alternative food for students with food allergy was 35.7%; and the reasons for not providing such food was 'lack of cooking time and employees' (69.4%). Furthermore, 79.7% of participants provided nutrition education and counseling for students with food allergy and the reasons for not providing education and counseling was 'lack of time' (59.0%). Nutrition teachers (dietitians) with experience of job training related to food allergy comprised 53.7%. The mean score of importance of food allergy management was 4.02/5.00. The items with high scores of importance of
were periodical check on students with food allergy, sending newsletters or homepage posting of foods causing allergy; however, provision of allergy-free or alternative food scored 3.64/5.00 points. The score of importance was significantly higher in those who checked on students with food allergy (p<0.05), offered allergy-free or alternative food (p<0.01), and in those with experience of job training (p<0.05) than those who did not. Therefore, in order to manage students with food allergy, nutrition teachers (dietitians) require on-going training on food allergy in order to practice provision of alternative foods and administrative support to the cooking personnel and facilities.

The purpose of this study was to evaluate the effectiveness of an intervention program using dietary consult and physical exercise conducted by public health center in Chuncheon city for obese adults. This study used a pretest-posttest design. The subjects were 58 out of 90 obese adults with body mass index (BMI) greater than
who completed all education sessions for 8 weeks. Data on dietary habits, dietary behaviors, nutritional knowledge, anthropometric parameters and biochemical indices and daily nutrient intakes assessed by a 24-hour recall were collected before and after the intervention program., in order to evaluate program effectiveness. After the intervention, there were positive changes in exercise status and dietary habits and nutrition knowledge accuracy. Especially, the answer of 'I drink a cup of milk every day' were significantly improved (p<0.001), and the answer of 'I don't overeat', which is a dietary attitude question was significantly improved (p<0.05). Dietary intakes of most of nutrients were not significantly different between pre-test and post-test. But calcium (p<0.05), potassium (p<0.05), vitamin A (p<0.01), vitamin E (p<0.05), and folic acid (p<0.05) were significantly increased in the female group after the intervention. Weight (p<0.05), BMI (p<0.01), blood pressure (p<0.001), were significantly decreased after program, but changes of skeletal muscle mass, body fat mass were not significant. Resting heart rate (p<0.01), flexibility (p<0.001), whole body reaction (p<0.05), grip strength (p<0.01) and balance (p<0.01) showed positive changes after the intervention. Blood glucose level in serum was significantly decreased (p<0.001). These results indicated that dietary education and exercise program was effective not only for weight reduction but also for the improvement of physical fitness in obese adults.
A Comparative Study on the Awareness of Health Risks and the Risk Reduction Measures Related to Sodium Intake between Female and Male University Students in Busan and Gyeongnam: An Application of Protection Motivation Theory
Jang, Soo-Hyun ; Yoon, Eunju ;
Korean journal of food and cookery science , volume 32, issue 1, 2016, Pages 136~146
DOI : 10.9724/kfcs.2016.32.1.136
The purpose of this study was to investigate whether there was a gender difference in motivating university students to decrease their sodium intake and to identify effective motivating factors. Within the protection motivation theory (PMT) framework, a survey questionnaire was developed to measure participants' perceptions on the severity of and the vulnerability to risk of serious diseases due to the high sodium intake, as well as the effectiveness (response efficacy) and the ability to perform preventive measures (self-efficacy). Behavioral intentions on five specific practices (checking nutrition label, consuming more fruits and vegetables, consuming less soups, avoiding spicy and pungent food, purchasing less instant or restaurant foods) related to decreasing sodium intake were also included. A total of 294 usable response data were collected from university students (92 male, 202 female) in Busan and Gyeongnam in June 2015 and analyzed using IBM SPSS 22. Severity was the highest (4.04) PMT factor followed by response efficacy (3.72), self-efficacy (3.42), and vulnerability (3.26). Compared to male students, female students thought that the threat was more severe (t=6.035, p<0.001) and reducing sodium intake would be effective to prevent serious illnesses (t=4.724, p<0.001), but their vulnerability and self-efficacy perceptions were not different from male students. Among the five items measuring behavioral intention, female students were more likely to increase fruits and vegetables consumption (t=3.811, p<0.001), while male students were more likely to avoid spicy and pungent foods (t=2.336, p=0.020). Based on findings of this study, the recommended strategy to effectively motivate university students to lower their sodium consumption level is the development of campaign focused on increased vulnerability perception, response efficacy, and ease of practicing preventive measures instead of emphasizing the severity of the consequences.
