This study was conducted to confirm the following effects of non-meat binders (NMB) on proximate composition, pH, cooking yield, amino acids, volatile basic nitrogen (VBN), thiobarbituric acid reactive substance (TBARS), and correlation of pork emulsified sausages during refrigerated storage. The following groups of sausage samples were manufactured: Control (non-addition), BBP (1% bovine blood plasma); PBP (1% porcine blood plasma), EWP (1% white egg powder), CPPP (1% commercial porcine plasma powder), ISP (1% isolated soy protein), SP (1% seaweed powder), and SC (1% sodium caseinate). When NMB was added, ISP, SP, and SC showed higher heating yields while PBP showed lower heating yields than the control. As a result of amino acid analysis, PBP, CPPP, and SC showed significantly higher serine content than the control. EWP and SC showed significantly lower TBARS values than the control group, and VBN did not exceed 20 mg% in any treatments until the 5^th week. These results demonstrate that SC is a NMB that can lower TBARS value while improving heating yield and serine content.

기능성 물질의 첨가가 기계발골계육 회수단백질을 활용한 돈육 소시지의 저장 중 품질 및 저장성에 미치는 영향에 대해 알아보고자, 햄부위 육만을 사용한 대조구와 대비 40% 기계발골계육 회수단백질을 활용한 T1, 40% 기계발골육에 0.1% 동충하초 분말을 첨가한 T2, 0.1% CLAT3 및 0.1% 누에고치 분말을 첨가한 T4로 나눠 실험에 공시하였다. 저장 0일차와 4주차에 대조구에서 유의적으로 높은 수분 함량을 나타내었다. 또한 T1에서 가장 낮은 수분함량이 나타났으며, T2, T3 및 T4에서 T1보다 높게 나타났다(p<0.05). 지방 함량의 경우, 저장 초기에는 대조구에서 낮은 값을, T2, T3 및 T4에서 높은 지방 함량을 보였으며, 저장 후기 즉, 4주차에는 40% 기계발골계육 회수단백질을 대체한 처리구들에서 높게 나타났다(p<0.05). 명도는 대조구에 비해 모든 처리구에서 낮게 나타나며, 적색도 또한 대조구에 비해 모든 처리구에서 전 저장기간에 걸쳐 높게 나타났다(p<0.05). 보수력의 경우, 저장기간에 따른 변화보다는 처리구들간의 비교 시 0일차와 2주차에서 대조구에 비해 T1에서 낮게 나타났으나 저장 2주차의 T1에 비해 T2에서 높은 값을 보이며(p<0.05), 유의적인 차이는 나타나지 않았으나 T3 및 T4 또한 높게 나타나 40% 기계발골계육 회수단백질을 활용한 돈육 소시지의 낮은 보수력을 동충하초, CLA 및 누에고치 분말 첨가를 통해 향상 시킬 수 있을 것으로 판단된다. 경도는 대조구에서 다른 처리구들에 비해 높게 나타났으며, 응집성, 검성 및 씹힘성 또한 경도와 같은 결과를 보였다. TBARS 측정 결과, 저장기간이 증가할수록 2주째까지는 감소하다가 4주째에 모든 처리구의 유의적으로 증가하였다(p<0.05). 또한 대조구에 비해 40% 회수단백질 첨가시 높게 나타났으나, 전체적으로 기능성 물질 첨가가 TBARS 값에는 큰 영향을 미치지 못하였다. VBN 값은 저장기간이 길어 질수록 증가하며 대조구에 비해 모든 처리구에서 낮게 나타났다. 미생물 수 측정 결과, 저장기간 별 비교에서 모든 처리구에서 저장기간이 증가할수록 총균수가 증가하였다(p<0.05). 또한 저장 2주째까지는 대조구에서 낮게 나타났으나, 저장 4주째에는 T2와 T3에서 낮게 나타났다(p<0.05). 따라서 40% 회수단백질의 활용은 돈육 제품의 명도 값을 낮추는 등 밝은 육색을 나타내며, 경도 등 조직 특성을 변화시켜 연한 조직감을 형성하였다. 또한 기능성 물질로 알려진 동충하초, CLA 및 누에고치 분말의 첨가는 VBN 값을 낮추었다. 그러나 기능성 물질로 알려진 동충하초, CLA 및 누에고치 등의 첨가를 통해 제품의 총균수 값을 감소시키지 못하였으며, 40% 회수단백질의 높은 TBARS 값은 제품의 품질을 떨어뜨릴 뿐만 아니라 돈육 제품의 품질 특성에 부합하는 적절한 회수단백질 첨가수준이 결정되어야 할 것으로 판단된다.

Objectives of this study were to investigate the acceptability of liver sausages, one of the most favorite product of meats, and to examine the applicability of pork liver in manufacturing sausages. Sausages containing different proportions of pork liver were manufactured with various processes and were tested and analysed by means of sensory evaluation. Based on th basic recipe for manufacturing sausages, fifteen recipies were proposed with different combinations of ingredients, followed by evaluations on their physicochemical and nutritional properties. Sausages manufactured with different methods (sliceable, spreadable, smoked spreadable) and different proportions of liver were also evaluated. The Findings from these experiments are summarized as follows: 1. As the percentage of the liver was increased, outer color of experimental sausages were significantly decreased. 2. The hardness, gumminess, chewiness were significantly decreased as the amount of liver increased. 3. Sausages containing 30% pork liver had best acceptability after swallowing. 4. The flavor and taste of liver in experimental sausages were significantly increased by adding liver. In summary, sausages containing 30% pork liver had best acceptability for consumption in terms of the indices measured in this study.

This study was conducted to evaluate the antioxidant activity of oven-dried ($60^{\circ}C$) tomato powder (TP) as affected by water solubility and to evaluate the effects of TP on the physico-chemical properties, and antioxidant and antimicrobial activities of emulsified pork sausages with two levels of TP (1% and 2 %). After fresh tomatoes were homogenized and dried at $60^{\circ}C$ oven, they were extracted by stirring with water. Then, the aqueous solution was filtered, and water soluble and insoluble tomato powders were obtained with freeze drying. In experiment I, total phenolic contents in oven-dried tomato powder, water soluble and insoluble powder were more than 2 g/100 g. The radical scavenging activity and iron-chelation ability of the water-insoluble extracts were higher than those of dried TP and water-soluble extracts. In experiment II, pH values and Hunter L values of pork sausages formulated with TP were reduced. However, hunter a and b values were higher than those of the control, and those effects were increased with increased levels of TP. 2-Thiobarbituric acid reactive substance values of pork sausages containing TP were lower than that of the control during refrigerated storage, regardless of the TP level. These results indicated that TP could be used as a natural color agent and antioxidant in meat products without defects.

This research applied and evaluated a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) using cytochrome b gene to detect pork contamination in meatballs from local markets in Surabaya and Yogyakarta regions, Indonesia. To confirm the effectiveness and specificity of this fragment, thirty nine DNA samples from different meatball shops were isolated and amplified, and then the PCR amplicon was digested by BseDI restriction enzyme to detect the presence of pork in meatballs. BseDI restriction enzyme was able to cleave porcine cytochrome b gene into two fragments (131 bp and 228 bp). Testing the meatballs from the local market showed that nine of twenty meatball shops in Yogyakarta region were detected to have pork contamination, but there was no pork contamination in meatball shops in Surabaya region. In conclusion, specific PCR amplification of cytochrome b gen and cleaved by BseDI restriction enzymes seems to be a powerful technique for the identification of pork presence in meatball because of its simplicity, specificity and sensitivity. Furthermore, pork contamination intended for commercial products of sausage, nugget, steak and meat burger can be checked. The procedure is also much cheaper than other methods based on PCR, immunodiffusion and other techniques that need expensive equipment.

This study investigated the effects of a healthy image on the preference and intake frequency of meat and animal products. The study looked into beef, pork, chicken, sausage, mackerel, cutlass fish, croaker, tuna, squid, shrimp, clams, fish cakes, eggs, milk, yogurt, ice cream, and cheese. A total of 359 usable surveys given to elementary school students, college students, and adults were collected using a convenient sampling method. While milk had the healthiest image, sausage had the least healthy image. The respondents preferred yogurt the most and sausage the least. The intake frequency of eggs was the highest and clams the lowest. The healthy image, preference, and intake frequency for all studied foods showed significant differences across both gender and age. The relationship between healthy image and preference was significant for all foods, and a healthy image always had a positive influence on preference. The relationship of healthy image and intake frequency was significant in 14 foods except for mackerel, cutlass fish, and tuna. Also a healthy image created a positive effect on the intake frequency of 14 foods.

This study was conducted to examine the effects of starch noodles (dangmyeon; SNs) with different starch sources and porcine intestines (PIs) with different pH on the rehydration stability of Korean blood sausage (sundae). Mungbean SN3 and PI3 (pH 9.18) showed significantly higher values of 80.69%-91.67% and 79.66%-80.98%, respectively, regardless of the drying methods (hot air, vacuum and freeze drying) (p<0.05). A number of larger pores were observed only in the cross-section of the freeze dried SN and PI through SEM. SN2 (potato starch) and PI3 (pH 9.18) showed lower expansion (⁎ΔL 6.90 mm) and higher expansion ratio (⁎ΔL 26.29 mm), respectively, after rehydration of freeze dried sample (p<0.05). From the application of SN2 (potato starch) and PI (0.5%-2.0% Na-pyrophosphate) to freeze dried sundae manufacturing, higher rehydration stability of more than 91.5% was obtained. These results suggested that potato SN and treatment of PI with Na-pyrophosphate is useful for desirable rehydration stability of freeze dried sundae.
