  • This study was performed to find out the usefulness of chestnut powder recovered from the inner layer, which used to be discarded. After the Physicochemical properties of the chestnut powder were examined, breads were prepared with 10-50% of chestnut Powder and the sensory quality was compared by QDA. Bread could be made even using up to 50% of chestnut powder, and in 20-30% of chestnut powder, the sensory quality was acceptable enough compared with wheat bread. Even though the low purity of the chestnut powder affected the flavor and color, the breads contained it were generally acceptable. Therefore, the chestnut powder recovered from the inner layer can be used as the effective food resource as itself, and with the higher purification to remove inner layer, it can be applied to more diverse food.

  • The purpose of this study was to develop functional breads added with Ganoderma lucidum (GL) extract which was well known for preventing various adult diseases and cancer. It was observed that bitter taste was increased with up to 8% GL extract while dough volume was increased at the first dough fermentation period and baking loss reduction was decreased. In terms of sensory evaluation, there were not so much significant differences with 2% added GL extract. In 4, 6, 8% added GL extract bread, it was found that 4% was ordinary and 6% and 8% were bad compared to the control bread. The bread with 2% added GL extract was excellent, 4% was ordinary and 6, 8% was badly evaluated in the internal texture. It's possible to make the functional breads baking with 2% GL extract which is similar to the control breads based on the above results.

  • The Korean diet, including breakfast, is becoming more Western, which could increase the risk of metabolic syndrome. Our aim was to assess whether breakfast patterns are associated with risk for metabolic syndrome in Korean adults. The study subjects (n=371; 103 men, 268 women) were employees of Jaesang Hospital in Korea and their acquaintances, and all subjects were between 30 and 50 years old. The data collected from each subject included anthropometric measurements, three-day food intake, blood pressure (BP) and blood analyses. The three breakfast patterns identified by factor analysis were "Rice, Kimchi and Vegetables", "Potatoes, Fruits and Nuts" and "Eggs, Breads and Processed meat". The "Rice, Kimchi and Vegetables" pattern scores were positively correlated with systolic (SBP) and diastolic blood pressure (DBP) measurements in men (P<0.05) and with serum triglyceride (TG) levels in women (P<0.05). The "Eggs, Breads and Processed meat" pattern scores correlated positively with weight, body mass index (P<0.05) and serum TGs (P<0.01) in men. The "Potatoes, Fruits and Nuts" pattern was associated with lower risk of elevated BP (OR 0.49, 95% CI 0.28-0.88) and fasting glucose levels (OR 0.51, 95% CI 0.26-1.00). In contrast, the "Eggs, Breads and Processed meat" pattern was associated with increased risk of elevated TGs (OR 2.06, 95% CI 1.06-3.98). Our results indicate that reducing the consumption of eggs, western grains and processed meat while increasing fruit, nut and vegetable intake for breakfast could have beneficial effects on decreasing metabolic syndrome risk in Korean adults.

  • The properties of water soluble powder of propolis(WSP), made with different levels(0, 20, 40, 60, 80%) of ethanol extract of propolis(EEP) and hydrocolloid were investigated, along with the quality changes of its bread after 7 days' of storage at $30^{\circ}C$ The yield of WSP containing 40% EEP treated at $160^{\circ}C$ was the highest at 59.3% and the brown color of all the powders tended to be darkened with increasing EEP content. The turbidity of WSP treated at higher temperature was decreased in its aqueous solution (10%, w/w), and this was considered to be due to the presence of minute nonsoluble particles. Antioxidative activities determined by DPPH(1,1-diphenyl-2-picrylhydrazyl) were the lowest in WSP treated at $140^{\circ}C$, while those of the WSP samples prepared at 160 and $180^{\circ}C$ were as high as that of WSP containing more than 40% EEP, regardless of EEP concentration. The propolis breads with added WSP made at $160^{\circ}C$ were selected as the most desirable powder for subsequent study. Bread with WSP40 was the heaviest while the volume loss of WSP80 was the greast after baking. The moisture contents of the propolis bread were drastically decreased until 3 days' of storage, but it was thought that WSP might be ineffective for the prevention of moisture loss. The pH of breads without EEP was decreased after 3 days' of storage, while that of the WSP breads remained almost unchanged until 5 days' of storage. Total bacterial counts also exhibited decay levels during the storage. In conclusion, water soluble powder of propolis is useful as a natural antioxidative and antibacterial material in various types of food.

  • This study was conducted to investigate the effect of baking on the physicochemical and sensory properties of white pan bread with red wine (RW). RW was substituted for water at four levels (0, 19, 38 and 63%). For bread crumb color, lightness decreased with increasing levels of RW, whereas redness and yellowness increased (p<0.05), in proportion to RW levels. Compared to control bread, specific volume of breads added with RW was decreased. The degree of dough raising power decreased significantly depending on the amounts of RW. The hardness of control bread was $87.35g/cm^2$ while the hardness of breads with RW ranged from 85.37 to $94.19g/cm^2$. Hardness, cohesiveness, springiness and gumminess of breads added with RW showed higher scores than the control group. In the sensory evaluation, the highest flavor and taste preference scores were observed in bread containing 38% RW, whereas the lowest score was observed in bread with 63% RW. Accordingly, the quality of bread can be improved by addition of 38% RW substituted for water.

  • This study examined the effects of sprouted brown rice (SR), gluten (G), and hydroxypropyl-methyl-cellulose (H) on the suppression of retrogradation in breads made with Korean wheat flour. An amylograph was used to determined the pasting properties of dough samples made with Korean wheat flour and additions of SR, SR+G, SR+H, and SR+G+H, respectively. In addition, a texture analyzer was employed to measure the hardness changes of bread samples left at room temperature for 72 hours. Finally, the type of retrogradation was calculated by the Avrami equation. The results showed that the addition of SR significantly decreased dough viscosity. However, the dough samples containing SR, G, and H all displayed reduced cold paste viscosity and setback, indicating a suppression of staling. The bread samples containing SR added to Korean wheat flour had increased hardness, but the addition of gluten (SR+G) reduced hardness. Upon examining the bread samples stored at room temperature for 24 hours, it was shown that the addition of G and H with SR (SR+G+H) suppressed retrogradation. Finally, the Avrami model data indicated that the type of retrogradation varied according to the addition of SR, G, and H. The breads made with hard wheat flour (HWF), WM, and WM+SR+H had similar Avrami exponents ($1.20{\sim}1.28$), while those for WM+SR, WM+SR+G, and WM+SR+G+H ranged from 2.7 to 3.3. Overall, the combined addition of SR and H was considered effective for preventing retrogradation in bread made with Korean wheat flour.
