This study was carried out to compare the quality properties of chicken breast surimi manufactured by four different procedures/methods. Surimi was made from chicken breast by washing two (T1) or four times (T2) with water as well as by pH adjustments at 3.0 (T3) or 11.0 (T4). The contents of moisture and crude fat were significantly higher in the surimi manufactured from pH-adjusted material than after washing. Again, collagen and yield were significantly higher in chicken breast surimi manufactured from washed than pH-adjusted samples, whereas crude protein was higher in the pH-adjusted than washed surimi samples. There was no significant difference in myofibrillar protein content among the surimi manufactured after different washing times and differences following pH adjustments were found. T4 showed highest myofibrillar protein content rating among the surimi samples. All physical characteristics were higher in pH-adjusted chicken breast surimi than in T1 and T2 washed surimi samples. The pH-adjusted surimi had higher hardness, gumminess and chewiness than washed surimi samples (p<0.05). The chicken breast surimi made by pH adjustments had higher lightness (L*) than when made by washing times, whereas pH 3.0-adjusted surimi samples had lower whiteness (W) then the other surimi samples. Myoglobin content was significantly higher in the surimi manufactured from pH-adjusted chicken breast samples.

기계발골 노계육을 수세하여 제조한 surimi의 저장중 oleoresin 향신료 첨가효과를 구명하기 위해 실험을 실시하였다. 계육 surimi에 rosemary, thyme, sage, mace, marjoram, bay를 각각 0.2% 첨가한 후 -18$^{\circ}C$에 14주간 저장하였다. Surimi의 pH는 냉동저장중 감소하였고, 대조구에 비해 향신료 첨가구가 더 많이 감소하였다. 향신료 첨가와 상관없이 냉동저장중 명도(L*)가 감소되고 적색도(a*)와 황색도(b*)가 증가하여 저장중 색깔이 어둡고 농후해졌다. Oleoresin 향신료를 첨가하면 대조구에 비해 L*과 a*가 낮고 b*가 높았으며 첨가구별 차이도 심하였다. 이것은 향신료의 자체 색깔에 더 많음 영향을 받았을 뿐 저장중 색깔 개선에 기여하지 못하였다. 향신료 첨가구는 대조구에 비해 gel 강도가 낮았다. 냉동저장중 모든 surimi에서 지방산화가 촉진되었으며 냉동 14주에 있어서 oleoresin sage가 대조구를 기준으로 TBARS가 42%를 나타내어 가장 산화가 억제 되었다. 결론적으로 본 연구에 이용된 6종류의 oleoresin 향신료는 surimi의 냉동저장중 지방산화를 억제시켰지만, 색깔과 조직감에는 개선 효과가 없는 것으로 나타났다.

To develop a new type of surimi with added citrus fruits, we examined the colors, textural properties and sensory evaluations of surimi after production. In the folding test, all samples had good flexibility, which suggested that addition of citrus fruits did not influence the flexibility of surimi. The pH in surimi samples was, in increasing order: lemon(Citrus limon), citron(Citrus junos), tangerine(Citrus unshiu), cumquet(Fortunella japonica var. margarita), and control. The pHs of each citrus fruits and the surimi with added citrus fruits were similar. Lightness increased in the following order: lemon, cumquet, control, citron, and tangerine surimi. Redness was high in the following order: tangerine, cumquet, control, citron, and lemon surimi. Yellowness increased in the following order: tangerine, cumquet, citron, lemon, and control surimi. There were no significant differences between lemon and control surimi. The hardness of surimi was highest in lemon, followed by citron, tangerine, cumquet, and control surimi. Although control surimi was the lowest, there were no significant differences among the samples. In terms of springness, it increased in the following order: tangerine, citron, control, lemon, and cumquet, but there were no significant differences among the samples. In sensory evaluation, overall acceptability decreased in the following order: cumquet, tangerine, control, citron, and lemon. Surimi containing cumquet got the best score in colors, textural properties, and taste except flavor. All samples got positive results in sensory ova luations, except for textural properties and taste of lemon and citron. Here, we confirm that surimi can be made with added citrus fruits, although we should examine in detail the quantities of added lemon and citron in a later study.

전분은 종류에 관계없이 첨가량을 증가시킴에 따라 gel 강도는 저하하였으며, RA급 냉동 surimi은 전분의 종류에 큰 영향을 받지 않은 반면, A급은 감자전분 및 수식 옥수수전분이 농도 증가에 따른 gel 강도 감소에 가장 적은 영향을 미치는 것으로 나타났다. WPC, DEW 및 SPI는 첨가량이 증가함에 따라 gel 강도는 감소하였으나, BPP는 gel 강도를 증가시키는 것으로 나타났으며, 이 같은 효과는 RA급에서 현저하였다. BPP의 gel 강도 증가 효과는 낮은 변성온도와 열 변성에 따른 구조 변화가 어육 gel의 matrix 강화에 영향을 미치는 것으로 판단된다. RA급을 이용한 어육 gel 제조시 백색도에 큰 영향을 미치지 않는 $2\%$ 범위 내에서 gel 강도 강화를 위해 사용할 수 있는 것으로 나타났다. Gel 강도 1000$\times$g를 제한 인자로 하였을 때, 냉동 surimi의 소모량이 가장 적은 formulation은 A급에서는 A급 surimi $37.8\%$ DEW $6.6\%$, 전분 $3.4\%$ 였으며, RA급에서는 RA급 surimi $40.9\%$, DEW $9.1\%$, 전분 $0.9\%$이었다.

Surimi-like samples were divided into four groups (C, surimi-like material made from Alaska Pollack with all cryoprotectant ingredients; T1, surimi-like material made from chicken breast with sugar and a sorbitol-free cryoprotectant; T2, surimi-like material made from chicken breast with a sugar-free cryoprotectant; T3, surimi-like material made from chicken breast with all cryoprotectant ingredients). Water and protein content were lower in Alaska Pollack surimi-like material (C) than those in chicken breast surimi-like material. Centrifuge loss and cooking loss were higher in C than those in chicken breast surimi-like material. Lipid oxidation (thiobarbituric acid reactive substances) was lower in T3 than others during storage. In a sensory evaluation, overall acceptability was significantly higher in C than those in other samples during storage. As a result, we found that the raw material composition (Alaska Pollack or chicken breast) had a large influence on the physico-chemical characteristics and quality of surimi-like materials, whereas cryoprotectant composition may have less influence on the physico-chemical characteristics and quality of surimi-like materials.

계육 surimi에서 trehalose와 oligosaccharide의 단백질 냉동변성 방지효과를 구명하기 위하여 본 실험을 실시하였다. 기계발골노계육에 0.5% 소금물(고기:용액, 1:4)로 2회, 증류수로 1회 수세하여 surimi를 제조하였다. Trehalose와 oligosaccharide를 각각 8%씩 혼합한 후 $-18^{\circ}C$에서 10주간 냉동저장하였다. 모든 Surimi의 적색도(a*)는 냉동기간동안 감소하였다. 냉동기간중에 trehalose, oligosaccharide, 무첨가 순으로 명도가 높고 적색도와 황색도가 낮아 색택 안정성이 있는 것으로 나타났다. 냉동기간중 surimi의 gel 강도(압착력, 경도, 탄성, 점착성)는 감소하였지만, trehalose와 oligosaccharide 첨가가 무침가구에 비해 유의적으로 높은 수준을 유지하였다. 냉동기간중에 부착성은 trehalose 첨가가 가장 높았다. 따라서 이들 당류가 계육 surimi에 단백질 냉동변성방지제로 효과가 인정되었으며, trehalose는 감미도가 기존 설탕보다 낮고 색깔 및 물성에서 oligosaccharide 보다 더 우수한 것으로 판단되었다.

다시마를 Vibrio sp.로 분해하여 제조한 SCD를 첨가하여 수산 연제품을 만들어 그 특성을 분석하였다. 원료의 최적 배합 비율을 구하기 위하여 mixture program의 modified distance design을 적용하였다. 수리미와 SCD의 첨가량이 증가할수록 hardness와 cohesiveness 값은 감소 후 증가하였다. SCD의 첨가량이 증가할수록 hardness의 값은 증가 후 감소하였으나 cohesiveness 값은 감소 후 증가하였다. 수리미와 물의 첨가량이 증가할수록, SCD의 첨가량이 감소할수록 gumminess와 brittleness의 값은 증가하였다. SCD의 첨가량이 증가할수록, 물의 첨가량이 감소할수록 수분보유력과 백색도의 값은 증가하였다. 수리미의 첨가량이 증가할수록 백색도의 값은 증가한 반면, 수분보유력은 감소하였다. ANOVA 분석에 의한 다시마 SCD 어육 gel의 Hardness 및 cohesiveness는 nonlinear model(Quadratic model)이 결정되었으며, gumminess, brittleness, 수분보유력 및 백색도는 linear model이 결정되었다. Constraint coefficient 값의 분석 결과 수리미는 hardness 및 백색도에 가장 큰 영향을 미쳤고, cohesiveness, gumminess, brittleness에서는 SCD가, 수분보유력에서는 물이 가장 큰 영향을 미쳤다. Hardness는 surimi-SCD의 상호작용이 있었으며 cohesiveness에서는 surimi-water의 상호작용이 나타났다. Modified distance design에 의한 다시마 SCD 어육 gel의 수리미, 물 및 SCD의 최적배합 비율은 각각 36.80, 57.05 및 4.14%이었다.

Surimi products are among the most prominent seafoods in Korea. Together with fish meat, wheat flour is a major ingredient in the preparation of surimi products. Rice flour, however, can be an effective ingredient in enhancing the rheological characteristics of surimi products. In this study, we evaluated the potential of rice flour as an agent to replace wheat flour in surimi products. The effects of rice flour milling types and addition methods on the rheological and sensory properties of surimi products were investigated. Among different addition methods, the surimi product containing non-treated rice flour showed better gel strength and sensory properties than products containing paste (1:1.3 rice flour/water, w/v) and steamed paste (steamed at $100^{\circ}C$ for 30 min). According to the gel strength results for surimi products with added roll-mill (40 mesh) and jet-mill (180 mesh) rice flours, the roll-mill rice flour shows good potential as a replacement for wheat flour. When considering gel strength and sensory properties, an effective amount of rice flour to add was 10-15% (w/w). In conclusion, the rheological and sensory properties of surimi products containing rice flour were comparable with those of a premium commercial surimi product. Therefore, rice flour might be an effective alternative to wheat flour for premium surimi products.

Utilization of soluble protein recovered from surimi wastewater using calcium powder of cuttle bone were examined. The crude ash content of the heat-induced surimi gel was increased linearly by increasing substitution ratio of recovered protein-ATC toward commercial surimi. Moisture (approximately $76\%$) and lipid $(0.2\%)$ contents were not change, but their protein contents were decreased 15.7 to $14.3\%$ depend on increasing of substitution ratio. The white index of the heat-induced surimi gel by color meter was increased up to $10\%$ of substitution ratio. There were no difference between $0\%\;and\;5\%$ substituted surimi gel in the gel strength. The sensory score on white index and texture of the heat-induced surimi gel did not change in 0 to $10\%$ as a substitution ratio of recovered protein-ATC toward commercial surimi, while decreased in more $15\%.$ The optimal substitution ratio of recovered protein-ATC as a bulking agent was $10\%.$ The heat-induced surimi gel prepared with $10\%$ substitution of recovered protein-ATC was similar to the content and composition of total amino. acids, and superior to calcium content and the ratio of calcium and phosphorus toward those of commercial surimi.

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.
