  • 방사선 조사에 의한 고춧가루의 매운맛 성분과 색의 변화를 분석하기 위해 고춧가루 (Capsicum annuum) 를 진공상태에서 포장한 후, 3, 5 및 7 kGy 의 감마선을 조사하였다. Capsacinoids 함량을 HPLC에 의해 분석하였을 때, total capsanoids 함량은 유의적인 차이를 보이지 않았으나, capsaicin은 조사선량이 클수록 증가하였고, dihydrocapsaicin은 변화가 없었다. Scoville test에 의한 매운맛 평가 결과, 0, 3 및 5 kGy 로 조사된 고춧가루의 매운맛 강도는 유사하였으나, 7 kGy 조사된 고춧가루는 매운 맛 강도가 높게 평가되었다. 고춧가루의 붉은 색을 나타내는 대표적인 색소인 capsanthin을 HPLC로 분석하였을 때, 변화가 없어 방사선 조사에 의한 영향은 없었다. 그러나 고춧가루의 붉은 색 정도를 색차 계로 측정하였을 때 Hunter a value (redness) 는 조사선량이 커질수록 증가되는 것으로 나타났다.

  • Two kinds of sweet potato puree were prepared with Benihayato cultivar of yellow sweet potato with or without $\alpha$-amylase enzyme treatment. Chemical and rheological properties of enzyme-treated puree were different from those of control puree. Reducing sugar content and iodine value increased by $\alpha$-amylase enzyme treatment, while alcohol insoluble solids and viscosity decreased by enzyme treatment. However, the changes of carotenoid content were not significantly different. Hunter-b-values(yellowness) were 27.19 and 23.54 for no enzyme-treated puree(NTP) and enzyme-treated puree(ETP), respectively. Hunter-a values(redness) were 2.24 and 6.05 for NTP abd ETP, respectively. Content of total carotenoid of canned puree heated at 13$0^{\circ}C$ for 30 min decreased by 59 percents.

  • Possibility of utilization of fig as a source of vinegar was tested. Alcohol fermentation was conducted by inoculation of Saccharomyces bayanus into fig juice. After 5 days of fermentation at 27oC, fig wine with alcohol content of 13.6%. Then fig vinegar was produced by cultivation of Acetobacter sp. E which was isolated from fig vinegar. Optimum concentration of alcohol, starter content and fermentation temperature for the acid production were 8~9%, 5% and 27~30oC, respectively. More acetic acid was produced by adding 0.5% of yeast extract and 0.01% of Ca pantothenate. Adjustment pH of culture broth with acetic acid and shaking cultivation method were not effective in higher yield of acid production. Addition of sulfite up to 50 ppm did not inhibit for acetic acid fermentation. Addition of 1% bentonite or 1% kakishibu was more effective for the clarification of fig vinegar than any other clarifying agents tested. During aging and racking, acidity, absorbance and tannin content of fig vinegar decreased, while redness and yellowness increased. Aged and racked fig vinegar showed higher sensory score than non aged one in the aspects of color and overall acceptability.

  • This study was conducted to investigate the quality characteristics of cookies added with different levels of tomato powder. Cookies were prepared with five different levels of tomato powder (0, 2.5, 5.0, 7.5, and 10.0%) and the physicochemical properties were examined. The pH of cookie dough decreased significantly by the addition of tomato powder (p<0.05). Crude protein and ash content of the cookies containing 5.0, 7.5 and 10.0% tomato powder were significantly higher than those of control and those with 2.5% (p<0.05). The spread factor of control cookie was lower than that of cookies containing 5.0, 7.5, and 10.0% tomato powder. The incorporation of tomato powder in cookies lowered the lightness values but increased redness and yellowness values. Rheology testing showed that cookies with 5.0, 7.5, and 10.0% tomato powder had significantly lower hardness value than control. Sensory evaluation revealed that overall desirability scores were not significantly different between control and tomato powder added groups. Therefore, cookies with up to 10.0% added tomato powder would be as acceptable as control cookies without depressing cookie quality.

  • In order to investigate the possibility of lwo fat meat products, beef patties were prepared with gums such as carrageenan, methyl cellulose, and xanthangum. The quality characteristics of beef patties were examined. Moisture contents of raw and cooked patties of control were lower than those of patties containing gums, and fat content was higher than those of containing gums. There was no significant difference in the protein contents of patties. In case of L-value(lightness) of raw patty, the control was higher than those patties containing gums. a-(redness) and b-value(yellowness) among patties were not significantly different. Cooking yield, fat retention, and water holding capacity of beef patties containing gums were higher than control beef patty, but salt soluble protein and gel strength were not significantly different. Significant difference did not exist among beef patties in hardness, but the chewiness and gumminess of patties containing gums were higher than control. In case of sensory evaluation, there was no significant difference among patties in aroma and palatability. Texture of control was higher than patties containing gums, and juiciness of control was higher than patties containing carrageenan.

  • The purpose of this study was to investigate the quality characteristics of frozen cookies made with 3%, 6%, 9% buckwheat flour. The higher amount of buckwheat flour added to the frozen cookies, the greater the decrease in water activity, hardness, Max. G and brittleness compared to control. Lightness, redness, and yellowness of the cookies with buckwheat flour were slightly lower than those of control. Brown color and buckwheat odor of the cookies with buckwheat flour were higher, whereas egg odor and butter flavor were lower than those of control. Overall acceptance of the frozen cookies with 3% buckwheat flour was high.

  • The study aimed to determine the optimal mixing ratio of two different amounts of Letinus edodes powder and egg for preparation of pasta. The complete analysis was conducted using the Design Expert 7 program (State-Easy, Minneapolis, MN). Response surface methodology revealed 10 experimental points, including two replicates for L. edodes powder and egg. L. edodes pasta formulation was optimized using rheology. Lightness and redness displayed a lineal model pattern, whereas yellowness was represented by a quadratic model. The sensory evaluation parameters of texture, color, flavor, appearance and overall quality showed significant differences for color (p<0.01), flavor (p<0.05), texture (p<0.05) and overall quality (p<0.05). All sensory parameters showed significant values in a quadratic model. The optimum formulations processed by numerical and graphical optimization were determined as 15 g of L. edodes powder and 37.5 g of egg.

  • The objective of this study was to evaluate the quality characteristics of Dasik containing different levels of jujube paste (0%, 60%, 70%, 80%, 90%). Moisture composition of the paste ranged from 19~29% As the content of jujube paste increased, the lightness (L) and yellowness (b) decreased while redness (a) increased In the texture profile analysis, as the content of jujube paste in Dasik content increased, the hardness decreased Cohesiveness and springiness did not show significant differences according to amount of jujube paste. The results of the sensory evaluation show that sweetness, bitterness, and overall acceptability were the highest in Dasik containing 80% level jujube paste.
