상백피, 곰피 및 강황 추출물 첨가에 의한 카스텔라의 저장성 및 품질증진 효과 (Effect of Morus alba Root Bark, Ecklonia stolonifera, and Curcuma aromatica Extracts on Shelf-life and Quality of Castella)

  • 상백피, 곰피 및 강황 혼합 추출물 첨가가 카스텔라의 저장성과 품질에 미치는 영향에 대해서 알아보았다. 15일간 저장하여 일반세균수와 곰팡이수를 측정한 결과 저장기간 전반에 걸쳐 무처리구에 비하여 첨가구의 미생물 생육이 억제되었으며, 첨가구의 산화보호지수가 높아 산화방지에도 효과가 있음을 알 수 있었다. 색도의 경우 무처리구에 비하여 첨가구의 명도와 적색도는 감소하였으며, 황색도는 증가하였다. 관능평가에서는 모든 항목에서 상백피 0.25%, 곰피 0.25% 및 강황 0.125% 첨가구가 가장 높은 점수를 받았으나 상백피 0.75%, 곰피 0.75% 및 강황 0.5% 처리구가 가장 낮은 점수를 받았다. 이상의 결과를 종합해 볼 때 상백피, 곰피 및 강황 혼합 추출물을 각각 0.25%, 0.25% 및 0.125%의 농도로 첨가할 경우 카스텔라의 저장성, 품질 증진 및 관능 개선 효과가 있을 것으로 사료된다.

  • This study investigated the effects of mycelium and culture supernatant of Cordyceps ochraceostromat(Co) on air way hyper-responsiveness, pulmonary immune cell infiltration, and Th2 cytokine expression in animal models of atopy and asthma. After ConA(+/-) activation of mouse primary spleen cells, decreased IL-4 and IL-13 cytokine production were seen in the presence of Co mycelium extracts and culture supernatant. The asthma model involved mice sensitized to ovalbumin by i.p. injection treatment; Co mycelium extract was also injected. The atopy model was the dinitrofenylbenzene-treated mouse ear. Ear thicken ing induced by DNFB was decreased by Co mycelium extract, and the extract also inhibited lung cell infiltration in ovalbumin-induced asthmatic mice. The results thus indicated that the Co mycelial extract reduced the undesirable immune responses seen in asthma and atopy.

  • Since 1985, the growth rate of population of the world is over that of the food production. The cultivated land and the grain production rate are decreasing every year. Therefore, the most serious crisis which we will meet in the 21st century will be food shortage. In order to solve this desperate shortage of food, besides trying to produce more food, the technology of post-harvest, food processing, and food packaging should be developed to reduce and make the best use of the amount of the already produced agricultural products for which a lots of cost and labors were invested, but are being wasted during food distribution channel due to their undeveloped technology.

  • Surimi has been traditionally used as the main ingredient in gelling foods, such as imitation crab sticks. However, it can also be used to manufacture snacks without gelling properties. To assess the properties of surimi as a snack ingredient, we prepared fried fish snacks with different surimi grades of Alaska pollack (AP) and threadfin bream (TB) and evaluated their quality characteristics. AP had significantly higher protein and gel strength values than TB did. Regarding color, TB showed significantly lower lightness (L) values and higher redness (a) and yellowness (b) values than AP did, consistent with the appearance of a brown color. TB had significantly lower hardness values, higher thickness expansion, and higher oil content than AP did. Hardness was found to be positively correlated with gel strength and negatively correlated with oil content. In the micro-structure images, more blistering was formed in TB, indicating higher expansion and crispiness. In the sensory evaluation, TB showed higher overall sensory acceptance than AP did, which is the result of its high color content, crispiness, taste, and aroma. Principal component analysis of the electronic nose and tongue revealed that the samples were clearly separated. In particular, TB had more aromatic components than AP in the electronic tongue. Our findings indicate that gel strength, which determines the quality properties of surimi, does not need to be considered in snack manufacturing. In fact, surimi with low gel strength is a more suitable ingredient for snack manufacturing.
