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.

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.

The effects of salt concentration and heating conditions on the thermal gelation properties of surimi produced from mechanically deboned chicken meat (MDCM) were investigated. Chicken surimi was manufactured by washing (MDCM: 0.5% NaCl=1:4), standing, straining and centrifuging. The fat, water-soluble protein and heme pigment in the MDCM were removed by increasing washing cycles. The compressive force of the chicken surimi increased as the concentration of salt was increased from 0% to 5%. Total gel strength of the surimi measured by texture profile analysis showed a maximum in the range 3-5% NaCl. Microstructural analysis showed that the unfolding network structure of the surimi gel began to appear at NaCl concentrations>2%. The optimum heating condition for gelation was $90^{\circ}C$ for 40 min as this resulted in maximum values for measures of gel strength including compressive force, hardness, fracturability, adhesiveness, springiness, gumminess, chewiness and resilience. Chicken surimi gel formed by cooking at a heating rate of $1^{\circ}C/min$ to $90^{\circ}C$ showed better a texture than gels produced at $1.85^{\circ}C/min$. Our result show that a lower rate of heating improves chicken surimi gelation.

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.

This study was carried out to investigate gel forming and degradation properties (suwari and modori phenomena) of chicken surimi from mechanically deboned chicken meat (MDCM) at various setting temperatures and time. Chicken surimi was manufactured by a continuous process including chopping of MDCM, washing with 5% NaCl solution or pure water, standing, straining and centrifuging etc. Total process of washing for the MDCM from chopping to centrifuging was repeated over 3 cycles. Gel from prepared surimi were formed at $90^{\circ}C$ for 30 min after various setting treatments. The textural properties of gels were measured at the temperature ranges of low (10$^{\circ}C$), medium (25$^{\circ}C$ and $30^{\circ}C$) and high (45 to 70$^{\circ}C$). The compressive force (CF), hardness and fracturability of surimi gel at 10$^{\circ}C$ increased as setting time increased, and showed the highest value at 30 h of setting time. The CF and hardness of chicken surimi gel at 25$^{\circ}C$ and 30$^{\circ}C$ showed the highest values at 10 h of setting time. Most of gel strengths including CF, and texture profile analysis (TPA) values showed the highest levels in the range 47.5 to 52.5$^{\circ}C$ (p<0.05). The gel strength at 60$^{\circ}C$ increased slightly at 30 min, but then continued to decrease with longer setting times. There was no increase of gel strength at $70^{\circ}C$, but only a continuous decrease over setting time. In conclusion, suwari (gel setting) and modori (gel degradation) phenomena occur during the gel formation of surimi from MDCM. The temperature range in chicken surimi was 47.5 to 52.5$^{\circ}C$ for suwari and 60 to 70$^{\circ}C$ for modori.

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.

The mechanically deboned chicken meat(MDCM) has several limits in using for in using for in processed meat products as a main material because of poor color and textural properties, chance of microbial contamination and lipid oxidation. There has been a growing interest all over world in the application of MDCM to the surimi process. The surimi made from MDCM contains a high concentration of myofibrillar protein since this processing involves repeated washing processes with an aqueous solution in order to remove heme pigments, fat and other undesirable substances. The quality of the surimi made from MDCM is affected by various processing factors, such as kinds of wash solution, ion strength, washing cycle, temperature, pH changes, composition, part of muscle, particle size, and rigor state etc. A number of researchers havee investigated the effect of the various washing conditions on the properties of surimi gels. A fuller information of all the factors affecting surimi processing and gel formation by heat-induced gelation has not been known yet.

This effect of replacing pork with corn starch, chicken breast and surimi on the chemical composition, physical, texture and sensory properties of sausage were investigated during storage. Five treatments of sausage such as; T1 (10:0:0, %), T2 (10:5:0, %), T3 (10:10:5, %), T4 (10:15:10, %) and T5 (10:20:15, %) were prepared with replacement of pork with corn starch, chicken breast and surimi. The sausage made with pork meat served as control (C). The sausage in the control had higher moisture and fat contents, but lower protein content than the treatments (p<0.05). The sausages in the T2 and T5 had decreased pH values after 3 wk storage (p<0.05). The lightness value was lowest in the T3, while the yellowness values were lowest in the T5 during the storage. The TBARS (2-thiobarbituric acid reactive substance) values were lowest in the control in all storage times (p<0.05). However, the sausage in the control had higher VBN (volatile basic nitrogen) value than the treatments during the 1 wk storage (p<0.05). All treatments had significantly higher hardness, cohesiveness, springiness, gumminess and chewiness values (p<0.05) than the control. The results indicated that corn starch, chicken breast and surimi can used as a pork replacer, that it also improves the physicochemical and texture properties of pork sausages.

Functional and nutritional soluble proteins can be recovered from surimi (and surimi-like material) processing wastewater, reducing environmental problems and the cost of an irresponsible waste disposal. Recovered proteins may be added back at a low percentage to surimi products. The aim of this work was to evaluate the effect of the addition of soluble recovered proteins (RP), obtained from mechanically separated chicken meat surimi-like material (MSCM-SLM) processing wastewater by acidic pH-shifting, on the composition and texture of RP-MSCM-SLM, with RP contents of 0, 10, 20 and 30% (w/w) in the mixture. For that, proximate composition and gel properties were evaluated. The fat content of the MSCM-SLM was significantly reduced to 11.98% and protein increased to 83.64% (dry basis) after three washing cycles. The addition of 30% RP in the MSCM-SLM significantly augmented the protein content to 93.45% and reduced fat content from to 2.78%. On the other hand, the addition of RP was responsible for a drastic decrease in texture parameters, reaching 252.36 g, 185.23 g.cm, and 6.97 N for breaking force, gel strength and cutting strength, respectively, when 30% of RP was included in the MSCM-SLM. It was concluded that the obtained intermediary product (RP-MSCM-SLM) is a good option to applications in processed meat products where high texture parameters are dispensable, e.g., emulsified inlaid frankfurter-type sausages, but high protein content and low fat content desired.
