This study was a preliminary investigation of healthy breads in the domestic bakery industry and examined conditions for consumer purchases. The analyzed data will be used for future product improvements within for the domestic bakery market. The key results were as follows: First, the subjects' choosing of healthy breads was 'Usually' (34.1%) and women were more knowledgeable about healthy breads than men. About 31.2% of the subjects responded 'Do not know well', but 98% had clear purchase intentions and showed positive acclaims for healthy breads. Second, the ranking of selection factors that subjects considered when buying healthy breads was 'curiosity>taste>safety>health>price>diet>employee representation> brand'. Women (3.89) had more sensitive reactions than men (3.47) to the 'Diet' variable, and there were statistical differences in 'Health', 'Taste', and 'Employee explanation' (p<0.05, p<0.001). Finally, highly educated considered brand more (3.87).

Low glycemic index (GI) foods have been reported to be very important in the control of blood glucose levels in diseases such as diabetes mellitus and obesity, which are becoming more prevalent in Korea. Bread consumption at breakfast and as a snack is also on the rise. To provide low GI alternatives, breads supplemented with dietary fibers-fructooligosaccharide (FOS), ground whole rye, and 2 types of resistance starch (RS2 and RS4)-were developed. The GIs for these breads were evaluated with 13 healthy college students (M6, F7) and sensory tests were done. Four kinds of breads were made through the modification of a basic recipe for white bread (the control, B) as follows: for Bf, the entire amount of sugar was replaced with FOS. For Ryef, 50% of the white wheat flower was replaced with roughly ground wholerye (20 mesh: 12-20 mesh = 1 : 3) in addition to replacing sugar with FOS. For RS2f and RS4f, 20% of the white wheat flower was replaced with RS2 or RS4, in addition to replacing sugar with FOS. The overall preference score of Bf was similar to that of B, while those of Ryef, RS2f and RS4f were lower than that of B, but showed the acceptable degree of the overall preference. The glycemic indices of Ryef and RS2f were 46.1 and 45.9 respectively, which were significantly lower than the GI of B, 67.8. The GIs of Bf and RS4f were, however, 66.7 and 80.5 respectively, showing no significant difference compared to B. The glycemic loads for a 30 g serving were 9.5, 5.9, 6.2, 11.0 and 9.0 for B, Bf, Ryef, RS2f and RS4f, respectively. In conclusion, addition of RS2 or roughly ground whole rye to the dough formula significantly lowered the GI. Since the preferences shown for those two breads were acceptable, they may be recommended as a substitute for white bread fir persons who need blood glucose management. More studies on the bread making process are required to improve preference and acceptance. Although GI lowering effects for F and RS4 were not found in this study, further studies are needed to verify their effects.

Sodium restricted diets are known to lower blood pressure in salt sensitive, hypertensive patients. Thare is increasing evidence that potassium plays an important role as a protective factor in the regulation of blood pressure. The objective of the current study was to measure parameters of sodium, potassium, and chloride utilization as affected by feeding of substantial quantities of bread made from whole ground white torn meal, whole ground yellow corn meal, and whole ground wheat flour. The breads provided 40 percent of a caloric content of the constant, measured laboratory diet. The 28-day study was divided into an introductory period of 7-days and three experimental periods of 7-days each. Order of assignment to specific treatments for 12 healthy subjects were according to a complete randomized block design. Yellow corn bread diets resulted in the highest potassium retention (243 mg/day) and the lowest urinary sodium and potassium ratio (1.53 $\pm$ 0.26) numerically in comparison to the other test breads. The excretions of sodium and chloride were higher during controlled feeding periods than during the self-selected diet period(p < 0.05). This indicates a response to the higher intake of these electrolytes from the experimental diets than from self-selected diets. There was no significant difference in the effect of white corn bread, yellow corn bread, or whole wheat bread diet on electrolyte status in humans. However, the yellow corn bread diet resulted in a somewhat more favorable urina교 sodium to potassium ratio than that from white corn bread or whole wheat bread diet.

Yacon (Smallanthussonchifolius) is a root crop that contains high amounts of fructo-oligosaccharides (FOS). FOS has a sweet taste, is low in calories, and is known to promote intestinal tract health. In this study, various yacon concentrates were substituted for sugar in white pan bread to obtain healthy benefits from the use of FOS. The quality characteristic changes during storage of the white pan breadswith 0, 25, 50, 75 and 100% of added yacon concentrates instead of sugar were investigated. During storage, the water contents and water activities of the breads made with high amounts of yacon concentrates changed less than in those made with only sugar. The hardness and chewiness of the breads made with high amounts of yacon concentrates had lower values than those made with only sugar. Thus, bread made with yacon concentrates might exhibit increased moisture retention and decreased aging velocity. The substitution of yacon concentrates for sugar in pan bread improved the bread quality.

This study analyzed in nutrient contents changes of adult's favorite foods between March 2019 and July 2020 after policy implementation nutrient-poor foods based on special act on safety control of adult's dietary life in Korea. Among adult's favorite foods manufactured or sold in 2020 as well as 2019, calories and key nutrients in breads, ice creams and pizzas were improved in comparison to those in the other food groups. However, most of the changes in calories or key nutrient contents exist. The newly introduced candies, breads showed slightly greater improvements in calories and key nutrient contents than in 2019. On the other hand, some negative changes were found in newly introduced chocolates in comparison to previous ones. Overall, policy implementation on foods seemed to induce changes in nutrient contents of adult's favorite foods. In particular, nutrition education is reported to have a positive impact on adult's frequency and preference for processed foods, and more systematic and continuous nutrition education measures should be devised to help adult as consumers selectively purchase healthy foods. This research is meaningful in that it is the first study to analyze the quality changes of adult's favorite foods since the high-calorie and low-nutrient food management policy.

The purpose of this study is to investigate 5th grade elementary school girls' effort to recognize and use nutritional labels on processed foods and restaurant meals to encourage dietary behavior. The subjects (n=976) were divided into three groups (effort group, n=711; normal group, n=193; and no-effort group, n=72) depending on level of effort for the healthy dietary behavior such as eating balanced meals, eating three meals regularly, and eating meals slowly. In the effort group, the frequency of food intake for breads, ramen, noodles and fast foods was significantly lower, while frequency of food intake for fruits and vegetables and salad was significantly higher than in the other two groups. In the effort group, the ratio of the respondents that perception of nutrition labeling on processed foods and restaurant meals was 80.5% and 31.4% and the ratio of girls who checked the nutrition labeling at their point of purchase was 71.1% and 24.7%, respectively. Reasons given for not reading nutrition labeling for restaurant meals were 'not interested' for 34.6% of the effort group, and 52.2% of the no-effort group. Therefore, it is necessary to create an educational program on healthy dietary behavior, including how to read nutrition labeling and establishment of proper body image perception for elementary school girls.

This study investigated the characteristics of baking bread and cookies supplemented with taurine and the effect of taurine addition on BAC(blood alcohol concentrations) and UAC(urine alcohol concentrations). Healthy male college students were divided into two groups, the control and the taurine group. Bread was baked with the addition of 0, 2, 4 and 6% taurine and baked with the addition 0, 3 and 6% taurine. The bread containing 2% taurine showed the fastest fermentation among the 4 groups. Fermentation and oven-spring of breads baked with a taurine concentration greater than 4% of taurine disturbed. In some areas of the sensory test, the taurine supplemented bread had higher scores than the control bread. We served 6 g of taurine supplemented cookies with 1,000 $m{\ell}$ of beer to 8 students in the taurine group. After 2 hours of drinking beer, the BAC and UAC of the taurine group were found to be lower than the control group. But no difference was found in the alcohol excretion of their urine. From this study we concluded that the taurine has an effect on the detoxication of alcohol, which reduces the BAC.

As an attempt to develop a value-added food product, purple sweet potato powder was added in a model system of steamed bread as a healthy food ingredient and physicochemical properties such as moisture content, specific volume, spread ratio, color, texture as well as consumer preferences on the attributes such as uniformity, color, flavor, elasticity, chewiness, taste, and overall preference were evaluated. Moisture content ranged from 44.16 to 44.55% (wet basis) and appeared independent on the level of purple sweet potato (PSP) powder incorporation. As a result of the addition of PSP powder, the specific volume of steamed bread decreased from 3.22 to 2.55 mL/g, and value of 4.5% sample was significantly lower than other samples (p<0.05). On the other hand, spread ratio ranged from 2.01 to 2.53, and appeared to decrease as the PSP powder concentration increased (p<0.05), indicating a significant improvement. Lightness $(L^*)$ decreased significantly as the PSP powder content increased (p<0.05) for both dough and skin of the steamed bread. In addition, an increasing trend in redness ($a^*$-value) and a decreasing trend in yellowness ($b^*$-value) were noticed. Firmness increased significantly with the addition of PSP powder regardless of concentration (p <0.05); however, firmness was not significantly different among samples containing 1.5-4.5% PSP powder (p>0.05). Consumer acceptance test indicated that incorporation of 3% PSP powder in the formulation of steamed breads would be recommended.

본 연구는 서울지역에 거주하는 건강한 성인 남녀(남자 23명, 여자 10명) 33명을 대상으로 trans 지방 3.75 g을 첨가 한 쌀 빵, 콩 빵과 밀 빵의 섭취가 식후 혈장에서의 지방산과 지질흡수에 미치는 효과를 확인하기 위하여 실시하였다. 시험군은 각 군 당 11명씩 3군으로 분류하였다. 쌀 빵은 밀가루 40 g과 쌀가루 40 g에 trans 지방 3.75 g을, 콩 빵은 콩가루 30 g과 밀가루 50 g에 trans 지방 3.75 g을 첨가하였고, 밀빵은 밀가루 80 g에 trans 지방 3.75 g을 첨가하여 식빵 형태로 각각 조제하였다. 대상자들은 8시간 공복 후 각각의 빵을 섭취하고 0, 1, 2, 3, 4시간 후 채혈하였고, 이는 혈중 지방산과 trans 지방산의 농도 및 지질 수준 분석에 이용되었다. 포화지방산인 C16:0과 C18:0의 수준은 밀 빵을 섭취한 군에서는 시간의 경과에 따라 유의적인 차이를 보였으나 콩 빵과 쌀 빵을 섭취한 군에서는 섭취 후 유사한 수준이었다. C16:0은 콩 빵과 밀 빵을 섭취한 군에서는 섭취 1시간 후에 peak에도달하였으나 시간이 경과함에 감소하는 경향을 보여 섭취4시간 후 밀 빵 군에서는 변화량은 섭취 전의 수준과 유사하였으나 콩 빵 군에서는 섭취하기 전보다도 낮아지는 것으로 나타났다. C18:0은 섭취 1시간 후 콩 빵과 쌀 빵을 섭취한군이 밀 빵을 섭취한 군에 비해 유의적으로 감소하였으나 콩 빵과 쌀 빵 군 간에 유의적인 차이는 없었다. Trans 지방산인 C18:1t과 18:2t는 세 군 모두에서는 섭취 2시간 후 가장 높은 수준을 보였으며 섭취 4시간 후에는 콩 빵 섭취한 군에서의 C18:1t의 혈중 농도가 가장 낮았다. C18:1c은 섭취 4시간 후 콩 빵 군에서 가장 낮았고 쌀 빵 군에서 가장 높았다. 또한 콩 빵의 섭취는 TG의 증가를 효과적으로 억제하였다. 이상의 결과로 미루어 볼 때 콩 빵의 섭취는 밀 빵을 섭취했을 때보다 혈중 trans 지방산을 비롯한 포화지방산 농도와 TG의 수준을 저하하였으며 이것은 콩에 함유된 식이섬유와 생리활성물질들이 지방산과 지방의 체내 흡수율을 저하시키거나 흡수속도를 느리게 하는 때문으로 사료된다. 따라서 trans 지방산을 비롯한 포화지방산과 TG의 체내 농도를 저하시키기 위해서는 밀 빵보다 콩 빵의 형태로 섭취하는 것이 유익할 것으로 사료된다.

Recently, strong interest in the well-being and healthy food trends lead a spreading of rice processing products such as rice noodles, rice breads, and rice cakes. However, most of rice varieties developed in Korea showed very limited processing properties in processing of noodles compare to that of wheat flour. Moreover, low competitiveness as a raw processing materials due to high price give poor evaluations for rice noodles processing. To cope those barriers, 'Saemimyeon' a Tongil type high yielding variety with a high amylose contents was developed in RDA. 'Saemimyeon' showed about 10~32 % of increase in yield as 7.08MT/ha and 26.7% of high amylose contents together with easy grinding property of 65.7% of high chalkiness ratio. The both of milled as well as brown rice of 'Saemimyeon' were well fit for processing properties in rice pasta where the contents of rice flour for rice pasta was 99% (1% of Tapioka starch was intermixed in to the rice flour). A spaghetti type for wet noodles and macaroni type for dry noodles were developed, respectively. Each of pasta were showed relatively more or less an equal quality and panel test compare to that of durum wheat pasta products. Finally, rice pasta products could suggest an alternative idea for a new rice processing items where rice noodles market was stagnant.
