This study was carry out to investigate the quality characteristics of Korean native black ground pork compared with modern genotype ground pork during refrigerated storage. Korean native black pig and modern genotype pig were slaughtered at 75 kg and 105 kg of live weight, and for 240 days and 210 days of feeding periods, respectively. The ground lean pork (M. semimembranosus) was stored for 9 days at 4℃. The crude fat and crude protein contents were significantly (p<0.05) higher in Korean native black pork. The pH value after 5 days of storage was significantly (p<0.05) lower in Korean native black pork than in modern genotype pork. WHC of Korean native black pork was significantly (p<0.05) higher than that of modern genotype pork over time. The Korean native black pork maintained black reddish color because it had lower CIE L/sup */ value and higher CIE a/sup */ value than the modern genotype pork. CIE L/sup */, b/sup */, C/sup */ and h/sup O/ values decreased as storage time increased. TBARS (thiobarbituric acid reactive substance), POV (peroxide value) and FOX (ferrous oxidation xylenol orange) tended to increase as storage time increased in all of the groups, in particular, those values increased more rapidly in Korean native black pork. Total saturated fatty acid and stearic acid contents had significantly higher in Korean native black pork (p<0.05). 본 연구는 재래종 세절 돼지고기의 저장 중 품질 특성을 구명하기 위하여 개량종과 비교하여 실시하였다. 시험용 돼지고기로 240일간 사육된 평균체중 75 kg의 재래돼지와 210일간 사육된 평균체중 105 kg의 개량돼지를 이용하였다. 도축 후 세절돈육을 4℃에서 9일간 저장하며 실시하였다. 일반성분의 조성을 보면 재래종 돼지고기가 개량종에 비해 조지방과 조단백질 함량이 높고, 수분과 조회분 함량은 낮았다. 재래종 돼지고기의 pH가 개량종에 비해 저장 5일부터는 낮았고, 보수력은 저장기간 내내 유의적으로 높았다(p<0.05). 재래종 돼지고기는 명도가 낮고 적색도가 높아 개량종에 비해 검붉은 색깔을 지니고 있다. 저장기간이 늘어날수록 CIE L/sup */, a/sup */, b/sup */와 h/sup O/값들은 감소하는 경향을 보였다. TBARS, POV, FOX값 모두 저장기간이 증가할수록 유의적으로 증가하였으며 특히 재래종이 저장기간이 길어질수록 현저한 증가현상을 나타내었다. 재래종 돼지고기의 지방산 조성비율을 보면 총 포화지방산과 stearic acid 함량이 개량종에 비해 유의적으로 높았다(p<0.05).

In this study, the quality of sow pork was compared with commercial pork to evaluate sow pork as raw meat material for processing. Texture, cooking loss, color, pH, water, lipid, fatty acid, volatile profiles, and sensory characteristics of 3 parts (tenderloin, loin, hind leg) of sow and commercial pork were analyzed. In texture analysis, sow pork had significantly higher shear force compared to commercial pork (tenderloin: sow 143.19 N, commercial 107.79 N; loin: sow 173.62 N, commercial 120.65 N; hind leg: sow 211.76 N, commercial 112.80 N) (p<0.05). There were significant differences in cooking loss, color, and pH, but they differed by part. A total of 49 volatile compounds were identified, and there were significant differences in 22 volatile compounds. In the case of hexanal (one of the warmed-over flavors), which was detected on the largest scale, the relative concentration was significantly higher in the tenderloin of commercial pork (p<0.05). On the other hand, no differences were reported by sensory analysis for hardness, off-flavor, juiciness, oiliness, appearance, taste, and acceptability between cooked sow and commercial pork. This study provides a database on the quality of sow pork by parts, which is considerable to develop proceed meat products using sow meat.

조경옥(Kyung Ok Cho),김선임(Sun Im Kim) 한국식품영양과학회 2013 한국식품영양과학회지 Vol.42 No.5

본 연구는 녹차, 오룡차, 홍차 추출물 0.5, 1, 1.5, 2%를 비육돈육(B 등급) 등심 수육에 첨가하여 수육의 일반성분, 보수력, 경도, pH, 색도, 미생물 수준, 휘발성 염기질소, TBARS, 관능검사의 품질특성을 측정하였다. 녹차의 수분 함량은 3.4%, 조단백질 31.8%, 조회분 5.5%, 탄수화물 57.7%였으며 차 종류에 따른 유의적인 차이는 없었다. 그러나 조지방은 녹차 1.6%, 오룡차 1.0%, 홍차 0.9%로 녹차의 조지방 함량이 오룡차나 홍차보다 유의적으로 높았다(p<0.05). 돼지고기 수육의 수분 함량은 55.1%, 조단백질 38.6%, 조지방 5.2%, 조회분 0.9%이었다. 보수력은 모든 차 추출물 첨가 수육에서 유의적으로 증가하였으며(p<0.05) 차 종류에 따른 차이는 없었다. 경도는 모든 차 첨가 수육에서 추출물 농도가 높아질수록 유의적으로 증가하였으며(p<0.05) 홍차 수육이 녹차와 오룡차 수육보다 경도가 낮았다. 수육의 pH는 제조일에는 각 처리구와의 유의적인 차이는 없었다. 그러나 저장기간이 경과함에 따라 무처리 수육과 모든 차 0.5% 수육에서 pH는 유의적으로 감소하였으나(p<0.05) 1, 1.5, 2% 녹차, 오룡차, 홍차 수육에서는 저장 중 pH의 유의적인 차이는 없었다. 녹차 수육은 추출물 농도가 증가할수록 명도와 황색도는 감소하였고 적색도는 감소하다가 2% 녹차 수육에서는 증가하여 0.5% 녹차 수육과 같은 수준이었다. 오룡차 수육은 추출물 첨가 농도가 증가함에 따라 명도와 황색도는 감소하였고 적색도는 증가하였다. 홍차 수육은 추출물 첨가 농도가 증가함에 따라 명도, 적색도, 황색도가 유의적으로 감소하였다. 미생물 수준은 모든 차 처리 수육에서 추출물 농도가 증가함에 따라 미생물 수준이 유의적으로 낮았으며(p<0.05) 저장 기간이 증가함에 따라 미생물 수준이 증가하였다. 수육의 휘발성 염기질소 함량은 제조일에는 각 처리구와의 유의적인 차이는 없었으며 저장 기간이 경과함에 모든 수육에서 유의적으로 증가하였다(p<0.05). TBARS 값은 제조일에는 무처리 수육보다 1, 1.5, 2% 녹차 수육과 오룡차 수육, 모든 홍차 수육이 유의적으로 낮았으며, 저장 기간이 경과함에 따라 모든 수육에서 TBARS 값이 높아졌다. 관능검사 결과 홍차와 오룡차 1% 추출물 첨가 수육이 색, 향, 종합적 기호도의 점수가 가장 높았으나 유의적인 차이는 없었으며 맛 점수는 유의적으로 높았다. 이상의 결과를 종합하여 볼 때 녹차보다 오룡차와 홍차 추출물의 첨가가 돼지고기 수육의 이취를 감소시키고, 특유의 색상을 부여하여 관능적 품질을 향상시킬 뿐만 아니라 가열 조리 및 저장 중 지방산패를 방지하여 품질 변화를 최소화하는데 효과적인 것으로 평가되었다. 특히 돼지고기 수육의 품질향상을 위해서는 홍차 추출물의 이용이 가장 좋았으며 오룡차와 홍차 추출물의 최적 첨가 농도는 1%로 나타났다. This study investigated the quality characteristics of boiled pork with different amounts (0.5, 1, 1.5, or 2%) of green tea, oolong tea and black tea extracts. Characteristics measured included approximate composition, water holding capacity (WHC), hardness, pH, Hunter’s color value, total aerobic bacterial counts, volatile basic nitrogen (VBN), 2-thiobarbituric acid reactive substances (TBARS), and sensory qualities. Green tea approximately contained 3.4%, 31.8%, 5.5%, and 57.7% of moisture, crude protein, crude ash, and carbohydrate, respectively. There were no significant differences with the type of tea. However, the crude fat content of green tea, oolong tea, and black tea were 1.6%, 1.0%, and 0.9%, respectively. Green tea had the highest content of crude fat (p<0.05). Boiled pork approximately contained 55.1%, 38.6%, 5.2% and 0.9% moisture, crude protein, crude fat and crude ash, respectively. The WHC of boiled pork, with tea extract added, significantly increased and there were no significant differences according to the type of tea. The hardness of boiled pork significantly increased as the amount of tea extract added increased (p<0.05). The pH of the boiled pork was not significantly different after storage for one day, but significantly decreased in control groups and boiled pork with 0.5% of any tea extract added during storage. However, in boiled pork with 1%, 1.5%, or 2% of any tea extract added, pH was not significantly different during storage. The Hunter’s L and b values decreased in all boiled pork. The Hunter’s a-values also decreased in boiled pork with green and black tea extract added, but increased in boiled pork with oolong tea extract added. In boiled pork with tea extract added, total aerobic bacterial counts significantly decreased as the amount of tea extract added increased during storage (p<0.05). The VBN values significantly increased during storage in all groups. TBARS values were significantly lower in boiled pork with green tea extract added, oolong tea added (at concentrations of 1%, 1.5%, or 2%), and black tea extract added compared to control groups on the first day. The sensory evaluation results showed that the color, flavor, and overall acceptance of boiled pork containing 1% of oolong or black tea extracts had the highest scores but there were no significant differences. However, taste scores were significantly different (p<0.05). These results indicate that boiled pork has improved quality characteristics with 1% of oolong or black tea extracts added.

This study was conducted to investigate the meat quality characteristics of pork loin in 3 crossbred groups (30 pigs/group). The crossbreeds were LY female${\times}$D male, Y female${\times}$B male and L female${\times}$B male (L: Landrace, Y: Yorkshire, B: Berkshire, D: Duroc). Pork loins were collected from animals ($110{\times}120kg$ body weight) slaughtered in a commercial slaughter house and stored at $-3^{\circ}C$. Samples were analyzed for general composition, physico-chemical properties, meat and fat color, texture characteristics, sensory evaluation and fatty acid composition at 24 hrs postmortem, and TBARS (Thiobarbituric Acid Reactive Substances) values were determined at various storage times. The LYD pigs showed a higher back fat thickness than the YB and LB pigs. There were no significant differences in intramuscular fat, intermuscular fat, subcutaneous fat and springiness among the 3 crossbreeds. In addition, there were no significant differences in general composition, pH, drip loss, cooking loss and cooked sensory evaluation among the 3 crossbreeds (p>0.05). The shear force value of LB pork was significantly lower than other crossbreeds (p<0.05). Total heme pigment was significantly higher in YB pork compared to LYD and LB pork (p<0.05). The TBARS value of YB pork was significantly lower than that of LYD pork, except after the I day of storage (p>0.05). TBARS values increased significantly during storage for all three crossbreeds. The lightness (CIE L) of YB pork was significantly lower, while the redness (CIE a) was significantly higher in YB pork relative to the other crossbreeds. With regard to textural properties, the hardness and adhesiveness values were significantly lower in YB pork compared to LB pork. In fresh meat, the color of YB pork was significantly higher than the other breeds (p<0.05). The content of myristic acid (C14:0) was significantly lower, while the content of arachidonic acid (C20:4) was significantly higher in LB pork (p<0.05). These results show that the YB breed has the highest quality meat of the three crossbreeds.

Purpose: The objective of this study was to investigate the quality characteristics of pork and beef meat according to species (pork: modern genotype pork, Korean native black pork; beef: Holstein, Korean native cattle) and cuts (pork: shoulder, ham, loin; beef: loin, tenderness, round). Methods: The moisture content, protein content, fat content, ash content, fatty acid compositions pH, whater holding capacity, cooking loss, shear force, color, and sensory characteristics were measured in triplicate. Results: The moisture content, pH, cooking loss, and shear force of modern genotype pork were significantly higher than the Korean native black pork; in addition, the moisture content of loin was significantly higher than shoulder and ham. The fatty acid compositions for different parts of pork showed no significant differences. Among the sensory characteristics, the parameters of pork were not significantly different. The moisture content of Holstein was significantly higher than Korean native cattle. The fatty acid composition of beef could not confirm the specific differences. Water holding capacity of Korean native cattle was higher than Holstein, while cooking loss of Korean native cattle was lower than Holstein. Overall acceptability scores of Korean native cattle was higher than Holstein. Conclusion: The study results of several parameters in selected raw meat samples provide useful information for developing new strategies to improve the quality of meat products consumption.

This study was carry out to investigate the quality comparison of ground Korean native black pork compared with modern genotype pork by different fat addition. The Korean native black pig and modern genotype pig were slaughtered at 75 kg and 105 kg of live weight, and for 240 days and 210 days of feeding periods, respectively. The ground lean pork (M. semimembranosus) mixed with ground fat (10, 20 and 30%, respectively) was stored for 9 days at 4℃. The crude fat increased as fat content increased. The pH of two porks increased significantly during storage. It was lower the Korean native black pork during storage than modern genotype pork. The WHC (water-holding capacity) of Korean native black pork was higher than modern genotype pork. The Korean native black pork maintained black reddish color because it had lower CIE L* value and higher CIE a* value than the modern genotype pork. CIE L, b*, C* and h values increased with increasing fat content in two samples but all CIE color values decreased during storage. TBARS (2-thiobarbituric acid reactive substances), POV (peroxide value) and FOX (ferrous oxidation-xylenol orange) of ground pork during storage were increased as fat content increased. Lipid oxidation of Korean native black pork occurred more rapidly than modern genotype pig. The Korean native black pork tended to contain more saturated fatty acids compared with the modern genotype pork. Especially, stearic acid and total SFA (saturated fatty acid) content had significantly higher in Korean native black pork (p<0.05).

라이신 수준에 따른 재래흑돼지육과 개량종 돼지육의 해동후 냉장중 품질비교

강선문,채병조,김용선,강창기,이성기 강원대학교 동물생명과학연구소(구 강원대학교 동물자원공동연구소) 2005 동물자원연구 Vol.16 No.-

This study was carried out to investigate the comparison of meat quality of Korean native black porks and modern genotype pork fed high and low lysine levels of diets at growing and finishing stages during refrigerated storage after thawing. M. longissimus from Korean native black pigs (gilts) with a live weight of 65 kg and modern genotype pork (gilts) with a live weight of 110 kg were frozen at -80 ℃ for 1 month and placed in the dark room at 1℃ for 7 days after thawing. The moisture content was significantly lower in modern genotype pork fed high lysine level of diets than to the other treatments (p<0.05), but crude fat content was significantly higher in modern genotype pork fed high lysine level of diets (p<0.05). The pH value and sensory evaluation were significantly higher in Korean native black pork than to modern genotype pork (p<0.05), and the drip loss was significantly lower in Korean native black pork (p<0.05). CIE L*, ho and hunter L were significantly lower in modern genotype pork fed high lysine level of diets than to modern genotype pork fed low lysine level of diets (p<0.05). Myristate, palmitate and saturated fatty acid content were significantly lower in Korean native black pork fed high lysine level of diets than to Korean native black pork fed low lysine level of diet (p<0.05), but unsaturated fatty acid content and UFA/SFA ratio were higher in Korean native black pork fed high lysine level of diets (p<0.05). Consequently, as Korean native black pigs were fed high lysine level of diets at growing and finishing stages, saturated fatty acid content of pork increased but unsaturated fatty acid content and UFA/SFA ratio of pork decreased. And the water-holding capacity, color stability and sensory evaluation of Korean native black porks were better than those of modern genotype pork.
