The quality of bread made of sprouted brown rice ($20\%$), wheat flour and pumpkin powder was investigated. The bread was manufactured with 0, 1, 3 and $5\%$ pumpkin powder (W/W) with increasing and wheat flour. Volume of the breads were decreased from 4.68 mL/g to 3.60 mL/g as pumpkin powder contents increased from $0\%\;to\;5\%$. Lightness decreased with increasing pumpkin powder contents. Yellowness increased from 10.97 to 27.01 with increasing pumpkin powder contents. Textural characteristics of bread crumb were influenced by adding additives pumpkin powder. Hardness, adhesiveness and chewiness of bread decreased as the added level of pumpkin powder. In sensory evaluation, sensory scores for color, flavor and overall quality of bread increased with increasing pumpkin powder contents.

Soybean and residue contained 59.0% dietary fiber and makkolli residue contained 26.0% dietary fiber. The breads made from flour consisting of 90% wheat flour and 10% fiber materials were compared with that made with 100% wheat flour in terms of baking performance and consumer acceptance. Replacement of 10% wheat flour by soybean curd residue or makkolli residue increased water absorption and loaf weigh, but reduced loaf volume. Sensory panels could not accept favorably the bread made with the soybean curd residue or makkolli residue in flour replacement at 10% level. The protein content was increased from 13.5% to 15.4% in bread containing 10% soybean curd residue and to 16.4% in bread containing makkolli residue. The dietray fiber contents of the bread with soybean curd residue and the bread with makkolli residue were three-fold and two-fold higher than the bread with flour.
This research was accomplished to analyze the preference and the actual using patterns of the bakery products using functional ingredients by subjects' age. This survey was examined by the self-administered questionnaire method for 374 female subjects in Suwon. All respondents preferred breads than confectionaries with functional ingredients. As for the products of cooking ingredients, cookies, roll-cake, cake, chocolate, the preference of teenagers was higher than those of the other groups. Subjects preferred potatoes, fruits, rice and green tea as functional ingredients. Over thirties showed the high preference over beans, vegetables, mushrooms, ginseng and oriental herbs while fruits were highly preferred in teenagers and twenties. The ratio of using the bakery products with functional ingredients once or twice a week was higher in over thirties than those of the other groups. Subjects answered that they generally spent $3,000won\sim5,000won$ on those products. Functionality of products was considered as the more important factor in thirties than in the other groups. The lack of information about these products and functional ingredients was reported by teenagers and twenties. These results would be basic data for marketing or improvement of baking products with functional ingredients.
The purpose of this paper was to analyze domestic patents for food using edible insects. From January 1, 1980 to December 31, 2021, patents filed with the Korean Intellectual Property Office were searched, and a total of 242 valid patents were selected. The trend of Korean patent applications for edible insect food has increased since 2015, with 57 cases (the highest number) in 2017. As for the edible insects used in food, Bombyx mori L. were the most common with 127 cases, followed by Tenebrio molitor L. with 118 cases. By type of applicant, individuals accounted for the most, with 132 cases. As a result of grouping patents by food classification, 67 cases of edible insects were used in snacks, breads, and rice cakes. As a result of patent analysis, an effort was made to supplement insufficient nutrients by adding nutritionally excellent edible insects to existing foods, and efforts were made to improve the sensory properties of insect foods. It is expected that this study will contribute to establishing future R&D directions and patent application strategies related to edible insect food.

Rice has been the most important staple food in everyday meals of Korean people for thousands of years. Nowadays, it is getting increasingly used as flour ingredients in a variety of processed foods, so that it is consumed in more diversified ways. As a consequence, production volume of rice flour to manufacture rice cakes, noodles, breads, or confectioneries is recently getting increased in Korea. But there are not sufficient research outcomes to guarantee Korean consumers microbiological qualities of rice flour as well as rice. As a preliminary experiment, therefore, the microbiological profiles (aerobic mesophilic bacteria (AMB), spore-forming aerobic bacteria (SAB), lactic acid bacteria (LAB), yeasts and molds (YM), and Escherichia coli and coliforms) have been monitored for nine retailed white rice samples in this study. AMB counts ranged $10^2-10^6$ CFU/g for all the nine white rice samples. All the nine rice samples have SAB counts within a narrow range $(1.0{\times}10^2-2.5{\times}10^3$ CFU/g). LAB was detected in two white rice samples ($4.0{\times}10^2$ and $3.7{\times}10^3$ CFU/g), YM was detected in one white rice sample ($2.0{\times}10^2$ CFU/g) only. E. coli was not detected from all the nine samples. Coliforms were detected in one white rice sample ($4.1{\times}10$ CFU/g) only. All the rice samples were conclusively considered to have various microorganisms, though most of them are harmless and some, such as coliforms, may be harmful.
The purpose of this study was to investigate the food behaviors and food preferences of teenagers by regional groups. The subjects were composed of 365 third grade students in middle schools from urban, rural and fishing areas in Kyungpook province. The data was collected by using a survey questionnaire. The results of the study are summarized as follows: Eating habits of 21-47% of the subjects, according to the regions, were poor and female students in large city showed the best eating habits while female students in fishing village showed the poorest eating habits. Out of the three regional groups studied, the subjects from the fishing villages had the highest rates of skipping meals and eating between meals. Out of all the people investigated, thirty to forty percent had unbalanced diets, the highest percentage coming from the urban areas and the lowest from the fishing villages. All together an allergic reaction to food was the highest in the fishing villages' subjects and female students were more sensitive compared to the male students. Students from the urban area had higher frequency of symptoms of lactose intolerance. Upon the investigation of the subjects 'food preferences, they preferred boiled rice to any other rice as a staple food. Cha jang myun was the most preferred out of all noodles and breads. It was found that teenagers preferred one course meal such as fried rice to a rice-centered regular meal. Out of all various meat soups, beef soup and beef-rib soup were preferred the most. As for subsidiary foods the most preferred were soybean paste stew and cuttlefish stew which they ate daily. There was a very high preference for fried foods, the most favored being pork cutlet followed by fried vegetables, sweet potatoes, and minced meat. The most preferred cooked vegetables were bean sprouts and seasoned cucumber. Seasoned cubed radish roots were the most preferred kind of kimchi. For desserts there was a very high preference for the following fruits: apples, plums, strawberries, and oranges. For beverages the most popular choice were chocolate drinks followed by orange juice, apple juice, milk and tomato juice. According to these investigations, most teenagers liked daily foods which they are used to. The study showed that on the whole the teenagers had poor eating habits. A problem that needs immediate attention is that female students and students from the fishing villages have a high rate of skipping meals. It is expected that the results of this food preference test of teenagers could be useful in the meal planning of middle school lunch programs in the future.

This study was carried out to investigate the effects of red yeast rice addition on the physical characteristics of sourdough starters ($SD1{\sim}4$) and the quality characteristics of sourdough bread (CSB, $SDB1{\sim}3$). Moisture contents of red yeast rice, wheat flour, and rye flour were 6.15, 12.53, and 8.56%; ash contents were 0.15, 0.44, and 1.64%; protein contents were 7.30, 12.57, and 11.18%; crude lipid contents were 0.97, 1.16, and 2.49%, respectively. The pH decreased with increasing red yeast rice addition. Reducing sugar and total sugar increased with increasing red yeast rice addition. Lactic acid bacteria were not detected from 0 day for all samples and was maximum on the 2nd day. The yeast counts of SD1 were not detected from $0{\sim}4th$ day, but $SD2{\sim}4$ increased until the 3rd day. Peak time, peak value, and width of tail of CSB were higher than $SDB1{\sim}3$, and they increased with increasing red yeast rice contents of sourdough. The fermentation expansive power of $SDB1{\sim}3$ was higher than that of CSB. Baking loss and specific volume of SDB1 were higher than other samples and when baking loss of CSB and SDB1${\sim}$3 increased, the specific volume increased. L values decreased with increasing red yeast rice contents of sourdough bread whereas, a and b values increased. Springiness and brittleness of CSB and gumminess of SCB1 were lower than other samples. Springiness, brittleness, and gumminess increased with increasing red yeast rice content of sourdough bread. The sensory evaluation indicated that color, hardness, springiness, sweetness, and sourness increased with increasing red yeast rice content of sourdough bread. Aircell non-uniformity of SDB1 was lower than other samples, whereas off-flavor was higher than other samples.
To find out what foods and dishes are being consumed by people with dyslipidemia, we have researched which food groups and dish groups are utilized in order to use for nutrition educations. The data was obtained from participants in 2001 KNHNS using the 24hours recall method. Ages over 30 years old are used for the analysis. Food and dish group intakes are analyzed by gender, age, residence, education, and economic status. Dyslipidemia are divided into A, B and C groups using guideline of dyslipidemia. The differences in food consumption were analyzed and assessed by GMDVF, DDS and DVS. SAS and SPSS were used for the data analysis. Overall, In food group, people in B and C (with dyslipidemia) have higher intake levels of vegetables, while people in A (without dyslipidemia) have higher intake levels of fruits (p < 0.05). In dish group, people in B and C (with dyslipidemia) have higher intake levels of rice dish, soups and kimchi, while people A (without dyslipidemia) have higher intake levels of breads and snacks, salad and fruits (p < 0.05). In the dietary patterns of main food group (GMDVF), the pattern excluding dairy (11011) revealed the highest proportion in all groups. DDS = 4 has the highest proportion in all groups. The proportions of subjects with the low dietary diversity score increased in B and C (with dyslipidemia). Food groups that most people do not consume were dairy and fruits. The level of DVS in A (without dyslipidemia) is higher than in B and C (with dyslipidemia). With these results, it is shown that people with dyslipidemia had worse quality patterns of food intake than those without dyslipidemia. Thus we should emphasize the balanced diet and educate people how to choose foods. So it is necessary to develop food guide for people with dyslipidemia.
BACKGROUND/OBJECTIVES: Hypertension is the major risk factor for cardiovascular disease, a leading cause of deaths in Korea. The objective of this study was to evaluate the effect of a nutrition education in reducing sodium intake and increasing potassium intake in hypertensive adults. SUBJECTS/METHODS: Subjects who participated in this study were 88 adults (28 males and 60 females) who were pre-hypertension or untreated hypertensive patients aged ≥ 30 yrs in Gyeonggi Province, Korea. These subjects were divided into 2 groups: a lowsodium education (LS) group and a low-sodium high-potassium education (LSHP) group. Nutrition education of 3 sessions for 12 weeks was conducted. Blood pressure, blood and urine components, nutrient intake, and dietary behavior were compared between the two education groups. RESULT: Blood pressure was decreased in both groups after the nutrition education (P < 0.05). In the LSHP group, levels of blood glucose (P < 0.05), total cholesterol (P < 0.01), and lowdensity lipoprotein-cholesterol (P < 0.05) were decreased after the program completion. Sodium intake was decreased in both groups after the nutrition education (P < 0.05). However, Na/K ratio was only decreased in the LS group (P < 0.05). Intake frequency of fish & shellfish was only significantly reduced in the LS group (P < 0.05), while intake frequencies of cooked rice, noodles & dumplings, breads & snacks, stew, kimchi, and fish & shellfish were reduced in the LSHP group (P < 0.05). Total score of dietary behavior appeared to be effectively decreased in both groups after the education program (P < 0.001). CONCLUSIONS: This education for reducing sodium intake was effective in reducing blood pressure and sodium intake. The education for enhancing potassium intake resulted in positive changes in blood glucose and serum cholesterol levels.
A survey was carried out to investigate into high school girls' food intake pattern and their behavior for weight control. The average height and weight of the subjects were 161cm and 52.9kg, while 53.3% of them usually had breakfast which 83.7% of them had steamed rice and dishes,64.7% of residue (46.7%) them often skipped breakfast because they didn't have to eat. Most of them had lunch which prepared from home at lunch time (75.7%), they cheesed foods at first by taste(71.9%), but they almost didn't consider the nutritional aspects, also they had very small amount of fruits and vegetables. They had snack more than once a day(93.4%), As snack, they used mainly cookies(39%), Ramyun and Ddukbocki(31.5%),and breads(17.6%). Meal time was shown to be short such as 10 or 20 minutes(40.7%), dinner was thought to be the most important meal(66.9%) In spite of their weight was standard(56.68%), they thought their style as fatty(48.1%) and they wanted to reduce weight(90.4%). 90.3% of all subjects were interested in weight control and students with standard sizes(52.7%) and/or/(p<0.05) lean weights(27 1%) had concerning about weight control significantly. The motive of attempt to weight control was shown to be effected by mass communication(49.1%) mainly, When they tried to lose their weight, 66.7% of them depended on their own judgement, while only 1.1% asked for the advice of a doctor. The most effective way to control weight was thought to increase the amount of exercise(52.7%) and to control the amount of food (32.2%).
