  • This study was to investigate the quality characteristics of sourdough bread made with 4 kinds of kamut sour starter. Kamut sour starters were made according to dough yield of sour starter and yeast adding on sour starter. We exmanined pH level, fermentation rate, specific volume, CrumbScan, moisture content, color value, texture analyzer, shelf-life test and sensory evaluation for observing quality characteristics of sourdough bread. From the results of pH measurement, kamut sourdough breads had lower pH value in dough and crumb pH than CON. In the experiment of dough's fermentation rate, CON had the rapidest fermentation rate among the samples initially, but the experimental groups also expanded as much as CON grew in spite of its slow fermentation. Specific volume and CrumbScan results suggested that CON had the largest volume. In addition, CM and TM had smaller volume than Pool and Biga. The sample that had the highest moisture content was Pool because its sour starter had the most amount of water. In color value test, CON had lighter crumb and crust color than other specimens. As a result of the TPA and shelf-life tests, CON had the softest hardness after 24 hours. However, Pool had similar hardness with CON after 72 hours. The result of the acceptance test of sourdough breads indicated that people prefered Pool and Biga to TM and CM. Difference test showed similar results with prior experiments. As the final outcome, Poolish was chosen as the optimal formula for kamut sour starter.

  • To get a basic information for improving Korean's pattern of comsuming red pepper and the possibility of its industrial production, consumer's ways of red pepper processing and his present dietary habits were surveyed and the results are follows; (1) Korean's daily consumption of red pepper was on the average 9.2 g on the basis of the whole dried red pepper. (2) The tendency of evading the home drying method was increased; 72.22% in urban community and 50.4% in rural community purchased the dried red pepper in the lump yearly. The household purchasing the fresh red pepper and using the home drying was 27.8% in urban community and 49.6% in rural community, so one third of urban household was still using the home drying method. The case of dependence on tine drying factory was no more than 2.6%. (3) Drying method was mainly sun drying which done on the poor circumstance like as the street side without the proper equipment of drying. Home process of red pepper by housewife was 70.8%, and the old, housekeeper were only 7.3% respectively. (4) The hygienic sense in the drying was rare; 68.8% was not washed and 51.9% of decayed red pepper was eaten. (5) Koreans prefered the strong pungency, deep red color and fine powder form. (6) While the 45.5% of seed was collected by second hand dealer and made use of as resources of edible oil, it was not used effectively due to complexity of its collection system. (7) While 40.1% desired the improvement of red pepper dietary life, 41.1% distrusted the present commercial red pepper powder on the market. From the results above, we conclude the fact many households have still hygienically poor red pepper processed at home, in spite of the red pepper is one of the most important spices in Korea. Considering the growing urban population, reduction of unemployed labor due to the increasing nuclear family and hygienic problems caused by the serious pollution, the improvement of red pepper processing method is urgently required. And it is believed that red pepper has a good prospect to be processed on the industrial scale in Korea.

  • This experiment was carried out to examine sensory testing for Mozzarella cheese, process cheese, Cheddar cheese and Cheddar cheese made with red pepper, garlic, ginger and welsh onion to develop new cheese varieties which can be prefered by Korean. The chemical composition and sensory testing of cheese were measured. The results were summarized as follows ; 1. Total nitrogen percentages in Cheddar cheese and spiced Cheddar cheeses were similar but those in process cheese and Mozzarella cheese were low. 5% NaCl soluble nitrogen percentages were highest in Cheddar cheese. 5% NaCl soluble nitrogen percentages in each cheese were different. Ripening degree, water soluble nitrogen, TCA soluble nitrogen and SSA soluble nitrogen percentages in each cheese were similiar level. 2. Spiced Cheddar cheeses were more breakdown than other cheese and ${\alpha}_s$-casein breakdowns faster than $\beta$-casein. 3. In the result of sensory evaluation, color score was high in Mozzarella cheese and process cheese. The color score of Cheddar cheese was high in 30's-40's and 50's- 50's. The color score of 10's and 20's was high in Cheddar cheese made with garlic. 4. Odor score was high in Mozzarella cheese and process cheese, too. The odor score of Spiced Cheddar cheeses was high in 10's. 5. Texture score was high in Mozzarella cheese, process cheese and Cheddar cheese. 6. Teste score was high in Mozzarella cheese, process cheese and Cheddar cheese. The taste score of spiced Cheddar cheese was higher in 10's and 20's than that in 30's-40's and 50's-50's.
