  • 본 연구는 자원량이 감소하고 있는 명태 등의 백색육 어류를 대체하기 위하여 백색도가 높고 잠재 자원량이 많지만 특유의 비린내가 있고 겔화가 어려운 대왕오징어에 겔 강화제를 첨가하여 품질이 향상되고 비린내를 줄인 대왕오징어 어묵의 개발과 setting의 영향을 분석하였으며, 결과를 요약하면 다음과 같다. Mixture model로 설계한 14개의 실험구에서 konjac flour와 MTGase의 양이 많을수록 gel texture는 크게 향상되었으며, 대조구에 비하여 setting을 적용한 제품의 gel texture가 더 높아 대왕오징어 어묵의 제조에 setting 공정은 반드시 필요하다고 생각된다. 대왕오징어육, 수분, konjac flour 및 MTGase의 비율이 각각 45, 40.6, 10 및 0.2%일 때 gel texture가 가장 높아 최적 배합비로 설정하였다. 본 연구에서 제조한 대왕오징어 어묵은 감자전분을 첨가한 대왕오징어 어묵에 비하여 맛과 향에서 유의적으로 높아(p<0.05) 대왕오징어 특유의 비린맛과 향을 줄일 수 있다고 생각되며, 시판 어묵과 맛과 색에서 유의적인 차이가 없어(p<0.05) 산업적으로 백색육 어류를 대체하여 활용하는 것이 가능하다고 판단된다.

  • 8% 녹두전분 gel에서 관능검사의 cohesiveness는 기계적 검사의 어떤 특성치와도 유의적인 상관관계를 보이지 않았으나 관능검사의 shine, clarity, elasticity, hardness, overall quality는 기계적 검사의 특성치들과 유의적인 상관관계를 가진다고 분석 되었다. 10% 녹두전분 gel에서도 8% 녹두전분 gel과 비슷한 양상이었다. 또한 8% 및 10% 녹두전분 gel에서 관능검사의 shine은 기계적 검사의 L, a, b값과는 정의 상관관계이나 clarrty는 L, a, b값과는 부의 상관관계인 점으로 미루어 보아 관능적으로 윤기가 있고 불투명하다고 느낄수록 명도는 높고 적색 및 황색에 가까운 시료로 평가됨을 알 수 있었다. 이상의 결과에서 지방의 첨가는 녹두전분 gel의 texture에 상당한 영향을 미치는 것으로 평가되었고 2%의 지방을 첨가시킨 녹두전분 gel의 texture가 가장 좋은 것으로 평가되었다. 우리의 전통식품인 청포묵 제조시 texture를 좋게 하기 위한 지방의 첨가와 더불어 저장성 및 풍미를 높여줄 수 있는 다진 마늘의 첨가, 고추기름의 첨가와 영양배합 고려 및 간편성을 위한 탕평채 고명의 전분 gel에의 첨가등에 관한 연구를 계속하고자 한다.

  • Texture-modifying and freeze-thaw stabilizing effects of different wheat gluten and modified starches on surimi based-product were evaluated. The different incorporation manners of wheat gluten and modified wheat starch in surimi gel were also examined to evaluate their effects of textural properties on surimi gel. The addition of wheat gluten reduced the gel strength of surimi, but after freeze-thaw cycle it significantly improved freeze-thaw stability by reducing freexe-thaw expressible moisture and also by preventing rubbery texture development, Gluten-1 incorporated surimi gel showed higher functionality in forming cohesive gel determined by compressive and penetration force as wall as expressible moisture after freeze-thaw cycle. Surimi gel containing modified wheat starch showed better freeze-thaw stability that of modified potato starch. When a preblended mixture of wheat gluten and starch are incorporated into surimi gel, it made gel texture significantly softer as so in high sensory score. The compertition for moisture between gluten and starch is a main reason to show different way of textural modification.

  • The properties of surimi gel from Olive flounder Paralichthys olivaceus were evaluated with addition of various food additives and by heating under different conditions. The optimum heating conditions for get good textured surimi gel from Olive flounder was 40 minutes at $85^{\circ}C$. Optimum texture characteristics such as hardness, cohesiveness, chewiness, gumminess and gel strength of olive flounder fish paste can be acquired by washing the paste 2 times and by adding sodium chloride (2.5%), sodium polyphosphate (0.3%) and starch (4%), respectively. Furthermore, we compared gel texture characteristics and strength of manufactured Olive flounder fish surimi with commercial Alaska pollack to determine their commercial applicability. Texture characteristics and gel strength of Olive flounder surimi were higher than those of the commercial Alaska pollack surimi. In addition, both lightness and whiteness were higher in surimi gel from Olive flounder than from the commercial Alaska pollack.

  • This study was to investigate the relationship between the gel layer thickness and swelling boundary via strength measurements using texture analysis. The novel texture analysis approach was used to examine the dynamics of swelling behavior in a ternary polymeric matrix tablet. The method permitted the characterization of the changes occurring at the peripheral as well as within interior boundary of the swelling during water ingress. The increase in gel strength for pectin, HPMC, and a ternary mixture with gelatin was found to depend on polymer concentration. Therefore, this method is further applicable to characterize the swelling behavior and provide opportunity to differentiate the gel-layer from that of swelling boundary.

  • The rheological properties of acorn crude starch gel and refined starch gel were investigated by puncture test, back-extrusion test and retrogradation test. Puncture test was a useful method to compare the different gel type and concentration, and to calculate the compression and shear coefficient. Maximum extrustion force and adhesiveness were also examined by performing back-extrustion test. The retrogradation rate was analysed by Avrami equation in retrogradation test.

  • This study was conducted to investigate the quality characteristics of frozen stored mungbean starch gels added with sucrose fatty acid ester (SE). The study showed a delay of gelatinization of mungbean starch by SE addition through the measurements conducted by using Rapid Visco Analyzer (RVA) and Differential Scanning Calorimeter (DSC). In the color of SE added frozen stored gels, lightness (L) and yellowness (b) values were increased compared to those of values measured from freshly prepared gel, whereas redness (a) value was decreased. The addition of 1% SE on mungbean starch gel prevented the color change during frozen storage. Rupture stress and rupture energy of frozen stored gel was higher than those of freshly prepared gel, whereas rupture strain of frozen stored gel was lower than that of freshly prepared gel. The addition of 1% SE on mungbean starch gel prevented the change of rupture characteristics during frozen storage. Texture profile analysis(TPA) characteristics revealed a significant change of the gel texture during frozen storage by showing an increase of hardness of the frozen stored gels compared to the freshly prepared gels with newly discovered fracturability, which resulted to show a large difference of gel texture by showing the disappearance of adhesiveness and large reduction of cohesivenes. The addition of 1% SE on mungbean starch gel prevented the change of TPA characteristics during frozen storage. Scanning electron micrographs showed that network structure of frozen stored gel was more rough than that of freshly prepared gel, and the addition of 1% SE on mungbean starch gel could suppress the breakdown of network structure. Thus the addition of 1.0% SE on mungbean starch gel was appropriate method for remaining gel characteristics during frozen storage.

  • Interrelationship between results of large deformation (texture profile analysis, TPA) test and small deformation (creep) test on ohmic heated surimi gel, water-bath heated surimi gel, and commercial fish gel products (kamabokos) was examined. Creep test revealed ohmic heated gels have higher elastic modulus and viscosity values than water-bath heated ones, with differences of elastic modulus and viscosity between ohmic and water-bath heated gels being 18 and 28.5%, respectively. These differences were reflected in the higher hardness, cohesiveness, and chewiness values of ohmic heated gels in TPA. In TPA test, the differences of hardness and chewiness between ohmic heated gel and water-bath heated gel were 29.3 and 38.7%, respectively. It was concluded that with proper experimental design, the small deformation creep test which gives molecular level deformation data can be related to the large deformation TPA test indicating the sensory textural properties.

  • The typical texture profile analysis of acorn flour gel was investigated with Instron univ. testing machine by two experimental designs, 3$\times$3 latin square and $3^{3}$factorial experiment. As the result, it was revealed that Latin square is a useful method to reduce the number of experiments, in the case of a negligible interaction.

  • 본 연구는 자원량은 많지만 겔화가 어렵고 특유의 비린내가 있는 대왕오징어에 구약감자분말을 겔 강화 및 비린내 제거제로 첨가하여 대왕오징어 어묵을 개발하는 목적으로 결과를 요약하면 다음과 같다. Design expert D-optimal program으로 design한 14개의 실험구에서 구약감자 분말의 양이 증가할수록 strength, hardness, cohesiveness, elasticity, brittleness 및 gumminess와 같은 gel texture의 강도는 크게 증가하였으며, WRA 또한 증가하여 surimi gel의 품질이 향상되었다. 그러나, 대왕오징어 육과 물의 함량이 증가할수록 gel texture와 WRA가 감소하여 구약감자 분말의 함량이 대왕오징어 어묵의 gel 형성에 가장 큰 영향을 주었다. 구약감자 분말의 양이 증가할수록 whiteness는 감소하였으며 이는 구약감자 분말의 탁색에 기인한다. 대왕오징어 어묵의 제조를 위한 대왕오징어 육, 물 및 구약감자 분말의 최적 배합비율은 whiteness는 낮았지만 gel texture와 WRA가 가장 높았던 45, 40.8 및 10% 비율이었다. 최적 배합비율을 적용하여 제조한 대왕오징어 어묵의 관능검사 결과 감자전분을 첨가한 대왕오징어 어묵에 비하여 대왕 오징어 특유의 쓴맛과 비린내는 많이 제거하였으나, 시판 어묵과 비교하여 낮은 결과를 보였다. 그러나, 구약감자 분말을 첨가한 대왕오징어 어묵에 다른 조미성분을 첨가한다면 구약감자 분말을 첨가한 대왕오징어 어묵은 상업적으로 활용이 가능하다고 판단된다.
