This study evaluated the effects of adding blood levels to phycochemical properties, textural properties, and sensory characteristics of blood sausage. 4 treatment groups of blood sausage were produced, T1 (pork ham : pork blood = 60:15), T2 (55:20), T3 (50:25), and T4 (45:30). T1 had the highest moisture content, most cohesiveness, and gumminess, CIE L-value, CIE a-value, and CIE b-value of raw and cooked blood sausages. Protein content, fat content, ash content, and VBN values were not significantly different among the treatments. T4 was treated with the most added pork blood, and had the highest pH of raw and cooked blood sausages, cooking loss, and TBA values. T2's sausage was the hardest, but had more springiness, cohesiveness, gumminess, and chewiness than T4. The best scores were from T4 and had the most overall acceptability. The results of this study show that blood sausages containing 20% pork blood had higher improved quality characteristics in blood sausages. 본 연구는 영양학적으로 우수한 혈액을 활용한 식육제품의 품질 특성에 미치는 영향을 규명하여 혈액 소시지를 개발하고자 실시하였다. 수분함량, 명도, 적색도, 황색도, 지질 산패도, 응집성, 검성 및 씹음성은 혈액 첨가량이 증가함에 따라 감소하는 경향을 보였으나, 단백질 함량, 지방 함량, 회분 함량, 휘발성 염기태질소 함량은 혈액 첨가량에 따라서 유의적인 차이를 보이지 않았다. 경도 및 탄력성은 혈액을 20% 첨가한 처리구가 다른 처리구들에 비하여 높은 수치를 나타내었다. 또한 혈액을 20% 첨가한 처리구가 전체적인 기호도에서 가장 높은 점수를 받았으며, 색, 풍미, 연도 및 다즙성에서도 혈액을 20%첨가한 처리구가 우수한 평가를 받은 것으로 보여진다. 따라서, 활용도가 낮은 돈육 부산물 중 혈액을 활용하여 혈액 소시지를 제조할 시 혈액의 첨가량이 20%로 하는 것이 혈액 소시지의 품질 및 관능적으로 우수한 혈액 소시지를 제조할 수 있을 것으로 보여진다.

Purpose: The objective of this study was to examine the effects of pork liver levels on the quality characteristics of hamburger patties. Methods: The effects of the addition of livers concentrations from 0% to 20% were investigated based on chemical composition, cooking characteristics, physicochemical properties, shear force, and sensory characteristics of hamburger patties. Results: The increasing pork liver levels from 0% to 20% resulted in increased moisture content, ash content, redness, reduction in diameter, and reduction in thickness of hamburger patties, but decreased the fat content, lightness, cooking yield, shear force and water holding capacity of hamburger patties. The protein content of hamburger patties with different amounts of pork liver showed no significant differences. The hamburger patties with increasing pork liver levels had lower color, flavor, juiciness, and overall acceptability scores, but the overall acceptability of control showed similar trends to T1 (treatments with 5% pork liver). Conclusion: Pork liver in the formulation showed similar quality characteristics as compared to control hamburger patties without liver, with best results obtained on adding up to 5% pork liver.

This study was conducted in order to evaluate emulsion mapping between emulsion stability and moisture content, cooking yield, hardness, protein solubility, apparent viscosity, and overall acceptability of pork or beef emulsion batters. The pork and beef emulsion batters were added to different parts of the meat. The formulations indicating low emulsion stability and high cooking yield were T1 (pork shoulder), T2 (pork ham), and T5 (beef tenderloin) treatments. Low stability, low hardness and protein solubility were also T1 (pork shoulder), T2 (pork ham), and T5 (beef tenderloin) treatments. The Pearson's correlation coefficients show that emulsion stability is negatively correlated with cooking yield (p<0.05), with a value of -0.90, and positively correlated with hardness (p<0.05), and protein solubility (p<0.01) with values of 0.65 and 0.59, respectively. This approach has been found to be particularly useful for highlighting differences among the emulsified properties in emulsion meat products. Therefore, the results obtained with emulsion mapping are useful in the making of new emulsified meat products of the desired quality.

카라기난, 트랜스글루타미제, 분리대두단백, 밀 식이섬유 첨가 종류에 따른 돈육 패티의 이화학적 및 관능적 특성을 조사하여, 결착제 첨가 종류에 따른 식육제품의 품질 변화를 알아보고자 하였다. 결착제 첨가 종류에 따른 보수력, 가열수율 및 수분함량은 대조구와 비교하여 카라기난, 분리대두단백 및 밀 식이섬유 첨가구가 높은 수치를 나타내었고, 직경감소율 및 두께감소율도 대조구와 비교하여 카라기난, 분리대두단백 및 밀 식이섬유 첨가구가 낮은 수치를 나타내었다. 전단력은 카라기난 첨가한 처리구가 가장 낮은 수치를 나타내었다. 또한 관능적 특성에서 연도, 다즙성 및 전체적인 기호도에서 대조구보다 결착제를 첨가한 처리구들이 높은 점수를 받았으나, 대조구를 포함한 모든 처리구에서 유의성이 인정되지는 않았다. 그러므로 결착제 첨가 종류에 따른 이화학적 및 관능적 특성 비교를 통하여 소비자 기호에 적합한 패티를 제조할 수 있는 기초자료로 활용할 수 있을 것으로 사료되며, 이러한 기초자료들을 바탕으로 다양한 첨가제들을 활용하여 다양성이 있는 식육제품 개발에 필요한 기초자료로 활용될 수 있을 것으로 보여진다. The objective of this study is to investigate the effects of binding agents (carrageenan, transglutaminase, isolated soy protein, and wheat fiber) on the physicochemical and sensory characteristics of pork patties. One percent of each pork patty formulation was prepared with one of the following carrageenan, transglutaminase, isolated soy protein, or wheat fiber. The lightness and redness values of raw and cooked pork patties with carrageenan, isolated soy protein, and wheat fiber were significantly higher than the control (p<0.05). The water holding capacity, cooking yield, and moisture content of pork patties containing carrageenan, isolated soy protein, and wheat fiber were significantly higher than the control (p<0.05). However, the reduction in diameter and thickness was lower than the control (p<0.05). The protein and fat content of the pork patties were not significantly different between the control and patties with binding agent addition. The shear forces of the pork patties with transglutaminase, isolated soy protein, and wheat fiber were significantly higher than the control (p<0.05), while the pork patties with carrageenan were significantly lower than control (p<0.05). Among the sensory characteristics, tenderness, juiciness, and overall acceptability of pork patties containing carrageenan, transglutaminase, isolated soy protein, and wheat fiber were slightly higher, although there was no significant difference. Therefore, pork patties containing binding agents are useful in making new ground meat products with desirable quality characteristics.

재구성 스틱형 육포의 저장 중 안정성 및 저장성 확보를 위하여 육포의 포장 방법 및 저장기간에 따른 pH, 수분활성도, 지방산패도, 경도, 총균수 및 관능검사를 측정하여, 육포의 품질관리에 대한 기초자료를 제공하고자 육포를 제조하여 상온에서 90일간 저장하면서 시료를 분석하였다. pH는 저장기간이 경과함에 따라 감소하였으나 일반포장과 진공포장 사이에는 유의적인 차이가 없었다 수분활성도는 진공포장에서는 저장기간이 경과함에 따라 유의적인 차이가 없었으나 일반포장의 경우는 저장기간이 경과함에 따라 감소하는 경향을 나타내었다. 간장 육포의 TBA 수치는 저장 15일부터 포장방법에 따라 유의적인 차이를 나타내었고 고추장 육포는 저장 30일부터 유의적인 차이를 나타내었다. 경도는 모든 처리구에서 저장기간이 경과함에 따라 증가하였고, 진공포장이 일반포장에 비해 경도의 변화가 적었다. 총균수는 저장기간이 경과함에 따라 증가하였다가 감소하는 경향을 나타냈으며 저장 동안 진공포장을 한 육포가 일반포장에 비해서 총균수가 적게 나타났다. 관능검사 결과도 저장기간이 경과함에 따라 대체적으로 진공포장이 일반포장과 비교하여 높은 점수를 받았지만 유의적인 차이를 나타내지 않았다. 따라서 일반포장은 소량의 공기를 포함하기 때문에 지방산패에 의한 산패취가 발생할 우려가 있어서 식감이 떨어질 수 있으므로 육포의 저장 중 안전성을 확보하기 위해서는 진공포장으로 유통하는 것이 저장성 측면에서 우수할 것으로 사료된다. The effect of packaging methods on the quality of stick type restructured jerky was investigated in terms of pH, water activity $(A_w)$, TBA (thiobarbituric acid) value, total bacterial counts, and sensory evaluation during storage at room temperature $(25^{\circ}C)$ for 90 days. The jerky was subjected to plastic or vacuum packaging at $(25^{\circ}C)$. The pH decreased slightly as storage time increased (p<0.05), but there were no significant differences between the packaging methods. The water activity of jerky in plastic packaging decreased as storage time increased (p<0.05), however jerky in vacuum packaging showed no significant change. Vacuum packaging resulted in a higher water activity value than plastic packaging. The TBA and hardness values decreased as storage time increased (p<0.05), and there were significant differences between packaging methods during the storage period (p<0.05). The total bacterial counts in vacuum packaged jerky were lower than jerky in plastic packaging. The sensory evaluation of each treatment decreased slightly as storage time increased (p<0.05), however there was no significant difference between packaging methods. Based on our findings, we conclude that vacuum packaging provides more effective storage than common packaging of jerky.

This study evaluated the effects of adding levels of rice bran fiber on the chemical compositions, cooking characteristics and sensory properties of ground pork meat products. Meat products were produced with products containing 0% (control), 1%, 2%, 3%, 4%, and 5% and rice bran fiber. The control had the highest protein and fat contents, cooking loss, reduction in diameter, CIE L value and CIE a value of uncooked product, and CIE L value of cooked product. The meat product containing rice bran fiber had the higher ash, pH, and CIE b value than the controls. The addition of 5% rice bran fiber resulted in the lowest cooking loss and L value of cooked meat products. Meat product with 2% rice bran had the highest water content, water holding capacity, hardness, color, tenderness, juiciness values. There was a significant difference among the ground meat products with respect to sensory properties, and meat products containing 1% and 2% rice bran had higher overall acceptability than the other meat products.

The effects of reducing pork hind legs concentrations from 80% to 60% and replacing the pork head meat with up to 20% pork head meat were investigated based on chemical composition, cooking characteristics, physicochemical properties, shear force, and sensory characteristics of hamburger patties. The increasing the pork head levels from 0% to 20% increased the protein content, pH, reduction in diameter, reduction in thickness, and shear force of hamburger patties, but decreased the moisture content, lightness, redness, yellowness, cooking yield, and water holding capacity of hamburger patties. The fat and ash contents of the hamburger patties with different amounts of pork hind legs and pork head showed no significantly different sensory characteristics from the control and all the treatments (p>0.05). The hamburger patties with increasing pork head levels had lower color, flavor, juiciness, and overall acceptability scores, but the overall acceptability of control showed similar trends to T1 and T2. Therefore, replacing pork hind legs with pork head meat in the formulation was successfully similar to control hamburger patties, with best results obtainedon replacing up to 10% pork head meat. 본 연구는 돈육 후지 부위를 영양학적으로 우수한 머리고기로 대체한 햄버거 패티의 품질 특성을 파악하여, 경제적이면서 고품질의 햄버거 패티를 개발하고자 연구를 실시하였다. 수분 함량, 명도, 적색도, 황색도, 가열수율 및 보수력은 머리고기 첨가량이 증가함에 따라 감소하는 추세를 나타냈으나, 지방 함량 및 회분 함량은 대조구와 머리고기를 첨가한 처리구간에 유의적인 차이를 보이지 않았다. 또한 머리고기 첨가량이 증가함에 따라 단백질 함량, pH, 직경감소율, 두께감소율 및 전단력은 증가하는 경향을 나타내었다. 관능적 특성도 색 및 풍미에서 대조구와 비교하여 15%까지 머리고기를 첨가한 처리구(T1, T2, T3)에서는 유의적인 차이가 인정되지 않았으며, 전체적인 기호도에서는 대조구와 비교하여 머리고기를 10%까지 첨가한 처리구에서 유의차가 나타나지 않았다. 따라서, 활용도가 낮은 돈육 부산물 중 머리고기를 활용하여 햄버거 패티를 제조할 시 머리고기의 첨가량이 10% 이하로 첨가하는 것이 햄버거 패티의 품질 및 관능적으로 우수한 식육제품을 제조할 수 있을 것으로 보여진다.

본 연구는 비육 단백질인 ISP와 CSP의 대체제로서 식이섬유인 wheat fiber를 첨가함으로써 돈육 유화물의 품질에 미치는 영향에 대해서 조사하고자 하였다. 돈육 유화물의 대조구와 모든 처리구에서 pH는 차이가 없었으며 (p>0.05), 보수력과 육색의 L-값은 대조구보다 처리구들이 높게 나타났다(p<0.05). 가열감량, a-값과 b-간은 처리구들이 대조구보다 낮게 나타났지만, 처리구들간에는 차이가 없었다. 유화안정성에서 수분리는 ISP처리구가 유의적으로 가장 낮은 것으로 나타났고, 유분리의 경우는 비육 단백질을 첨가한 처리구에서 낯은 것으로 나타났다(p<0.05). 점도는 대조구와 비교하여 처리구들이 높았지만(p<0.05), 처리구들 사이에는 차이가 없는 것으로 나타났다(p>0.05). 물성은 대조구와 비교하여 경도, 검성, 씹음성의 경우 모든 처리구에서 높게 나타났으나, WF-200 처리구와 대조구는 유의적인 차이가 없었다. 이상의 결과로 종합하여 볼 때, ISP와 CSP의 대체제로 wheat fiber가 새로운 기능성 소재로 타당할 것으로 사료된다. The purpose of this study was to investigate the effect of wheat fiber as a replacement for isolated soy protein (ISP) or concentrated soy protein (CSP) on the quality characteristics of meat batter. Meat batter formulations were prepared with 2% levels of ISP, CSP, or wheat fiber. The pH values of each formulation were not significantly different (p>0.05). The L-values of meat batter containing wheat fiber, ISP, or CSP were higher than the control, however the a- and b-values were lower than the control (p<0.05). Relative to the control meat batter, the water holding capacity, viscosity, hardness, gumminess, and chewiness of meat batter containing ISP, CSP, or wheat fiber was significantly higher than the control (p<0.05). All supplemented meat batters had significantly lower cooking loss and emulsification stability than the control (p<0.05), with no significant difference among the supplemented meat batters. The results of this study show that the use of wheat fiber as an ISP or CSP replacer does not affect the overall quality of meat batter.
