The aim of this study was to determine the relationship between sensory properties and Warner-Bratzler shear (WBS) for branded Hanwoo beef. Eight subprimal cuts purchased from the branded Hanwoo beef of 3 quality grades ($1^{++}$, $1^+$, 1) at 13 stores were determined the tenderness using WBS and evaluated the sensory properties (tenderness, flavor, juiciness, overall acceptance) by trained sensory panels. The results of sensory evaluation were analyzed by four WBS value classes (<3.46 kg, 3.46-4.09 kg, 4.09-4.72 kg, >4.72 kg). The results from the sensory evaluation (tenderness, flavor, juiciness, overall acceptance) for subprimal cuts of WBS force value less than 3.46 kg had high scores, whereas WBS force value more than 4.72 kg had low scores (p<0.05). Correlation coefficient of WBS measurements with sensory ratings was -0.67 (tenderness), -0.53 (flavor), -0.49 (juiciness), and -0.57 (overall acceptance). From these results, consumers can distinguish sensory taste of branded Hanwoo beef using WBS categories and beef industry can apply index of taste for brand Hanwoo beef by WBS categories.

Eight subprimal cuts purchased from the branded Hanwoo beef of 3 quality grades ($1^{++}$, $1^+$, 1) at 13 stores were evaluated the tenderness using Warner-Bratzler shear (WBS). The beef frequency ratio (%) depending on postmortem aging periods were investigated. The 37.5 (quality grade $1^{++}$), 45.8 (quality grade $1^+$), and 36.4% (quality grade $1^{++}$) of branded beef were aged for < 7 d, 26.6 (quality grade $1^{++}$), 47.2 (quality grade $1^+$) and 36.4% (quality grade 1) were aged for $7{\sim}13$ d, and 31.3 (quality grade $1^+$), 4.2 (quality grade $1^+$) and 25.8% (quality grade $1^+$) were aged for 14 to 20 d. The temperature of cold room in stores was ranged average 2.27 to $2.42^{\circ}C$. WBS values for ansimsal (tenderloin), witdngsimsal (ribeye), cheggtsal (shortloin), doganisal (knuckle) and moongchisatae (hind shank) from branded Hanwoo beef of quality grade $1^{++}$ were tender than those from branded Hanwoo beef of quality grade 1 (p<0.05). WBS values for ansimsal (tenderloin) were 2.56 (quality grade $1^{++}$), 2.76 (quality grade $1^+$) and 3.10 kg (quality grade 1), respectively, and those for doganisal (knuckle, quality grade $1^{++}$), hongdukesal (eye of round, quality grade $1^+$) and bosupsal (top sirloin, quality grade 1) were 4.76, 4.96 and 5.66kg, respectively (p<0.05). The frequency ratio (%) of WBS < 3.9 kg in the all subprimal cuts from branded Hanwoo beef of quality grade $1^{++}$ were 100 [ansimsal (tenderloin) and cheggtsal (shortloin)], 87.5 [witdngsimsal (ribeye)] and 62.5% [bosupsal (top sirloin)], whereas that of WBS > 4.6 kg were 50.0% [hongdukesal (eye of round) and doganisal (knuckle)]. The frequency ratio of WBS < 3.9 kg in the an subprimal cuts of quality grade $1^+$ were 100 [ansimsal (tenderloin) and witdngsimsal (ribeye)] and 44.4% [cheggtsal (shortloin) and gurisal (chuck tender)], whereas that of WBS > 4.6 kg were 66.7 [hongdukesal (eye of round)], 55.6 [doganisal (knuckle)] and 44.4% [bosupsal (top sirloin)]. The frequency ratio (%) of WBS < 3.9 kg in the all subprimal cuts of quality grade 1 were 88.9 [ansimsal (tenderloin)], 62.5 [cheggtsal (shortloin)] and 44.4% [witdngsimsal (ribeye)], whereas that of WBS > 4.6 kg were 100.0 [doganisal (knuckle)] 62.7 [hongdukesal (eye of round)], 62.5 [gurisal (chuck tender)] and 55.6% [moongchisatae (hind shank)]. From these results, subprimal cuts from branded Hanwoo beef were marketed with short aging periods and high frequency ratio (%) of WBS > 4.6 kg.

본 연구는 한우수소 10두에서 10부위(업진, 보섭, 채끝, 등심, 꾸리, 홍두깨, 목심, 설깃, 양지, 우둔)를 선정하여 성분조성 및 맛 관련물질 특성을 분석하였다. 칼로리 함량은 부위간에 유의적인 차이가 없었다(p>0.05). 10 부위내 콜레스테롤 함량은 홍두깨가 콜레스테롤 함량이 26.74 mg/100 g으로 가장 낮았고 업진이 31.08 mg/100 g으로 가장 높게 나타났으나(p<0.05) 다른 부위들간 콜레스테롤 함량에는 유의적인 차이가 없었다(p>0.05). 맛과 관련이 있는 유리아미노산 함량을 부위별로 비교한 결과 모든 부위에 glutamate와 alanine 함량이 각각 $94.33{\sim}216.36\;mg/100\;g,\;154.88{\sim}200.31\;mg/100\;g$로 가장 높은 수준으로 존재하였고 그 다음으로 arginine, phenylalanine 및 lysine으로 분석되었다. 부위별 inosine monophosphate(IMP) 함량은 업진, 보섭, 채끝, 홍두깨, 설깃, 우둔부위가 등심이나 목심 부위보다 유의적으로 더 많이 존재하는 것으로 분석되었다(p<0.05). Inosine 함량은 보섭과 설깃이 가장 많았고 반면에 hypoxanthine은 꾸리부위에서 가장 높게 나타났다(p<0.05). 부위별 총 콜라겐 함량은 업진부위가 가장 높았고 그 다음이 양지, 꾸리, 목심 부위가 높은 것으로 나타났다(p<0.05). 지방산 조성에서 등심부위가 다른 부위와 비교했을 때 stearic acid($C_{18:0}$) 함량이 유의적으로 높았고 우둔부위는 arachidonic acid($C_{20:4n6}$)의 함량이 가장 높은 것으로 나타났다(p<0.05). 총 포화지방산 함량은 업진, 등심 및 양지부위가 가장 높았고 총 불포화지방산 함량은 홍두깨 부위가 가장 높게 나타났다(p<0.05). This study was conducted to investigate the compositions of different cuts of Hanwoo bull beef. 10 cuts [Abjin (short plate), Bosup (top sirloin), Cheggt (striploin), Dngsim (loin), Guri (chuck tender), Hongduke (eye of round), Moksim (chuck roll), Sulgit (bottom round), Udoon (top round), Yangi(brisket)] were prepared from 10 Hanwoo bulls (-24 month old) slaughtered during 3 consecutive days. There were no significant differences in the calorie contents among the 10 cuts (p<0.05). In cholesterol content, Hongduke was significantly lower (26.74 mg/100 g) and Abjin was significantly higher (31.08 mg/100 g) than the other cuts (p<0.05). Free amino acid analysis revealed that there were high contents of glutamate (94.33-216.36 mg/100 g) and alanine (154.88-200.31 mg/100 g), followed by arginine, phenylalanine and lysine in the 10 cuts. In addition, Abjin, Bosup, Cheggt, Hongduke, Sulgit and Udoon had significantly higher inosine monophosphate (IMP) contents than Dngsim or Moksim (p<0.05). Inosine contents were highest in Bosup and Sulgit, whereas hypoxanthine contents were highest in Guri (p<0.05). Total collagen contents were significantly higher in Abjin followed by Yangi, Guri and Moksim (p<0.05). With regard to fatty acid composition, Dngsim had significantly higher $C_{18:0}$ than the other cuts, and Udoon had significantly higher $C_{20:4n6}$ than the other cuts (p<0.05). Total contents of saturated fatty acids (SFA) were significantly higher in Abjin, Dngsim and Yangi, whereas total contents of unsaturated fatty acids (UFA) were significantly higher in Hongduke than the other cuts (p<0.05).

This study was conducted to investigate the compositional properties by different cut of Hanwoo steer beef. 10 cuts [Abjin (short plate), Bosup (top sirloin), Cheggt (striploin), Dngsim (Ioin), Guri (chuck tender), Hongduke (eye of round), Moksim (chuck roll), Sulgit (bottom round), Udoon (top round), Yangji (brisket)] were prepared from 10 Hanwoo steers ($24{\sim}28$ mon old) were used for the experiment. Calorie contents were $2,205{\sim}3713.20\;cal/g$ and loin, striploin, short plate were significantly higher than the other cuts (p<0.05). Loin was highest in cholesterol content, whereas top round and eye of round were lowest among 10 cuts (p<0.05). There were no significant differences in soluble and insoluble collagen contents although chuck tender, chuck roll and bottom round contained significantly higher total collagen and loin and striploin contained significantly lower total collagen contents than the other cuts (p<0.05). The result from the analysis of free amino acids showed that glutamate and alanine contents were $275.99{\sim}536.04\;mg/100g$, $130.63{\sim}175.23\;mg/100g$, respectively and followed by arginine ($7.00{\sim}10.49\;mg/100g$), phenylalanine ($4.70{\sim}13.88\;mg/100g$), and leucine ($5.98{\sim}10.26\;mg/100g$) in 10 cuts. $1^{++}$ grade Hanwoo steer beef had significantly higher IMP (Inosine monophosphate) and inosine in eye of round (30.04% and 6.25%) and top round (33.44% and 6.28%), while hypoxanthine contents were significantly higher in chuck tender than the other cuts (p<0.05). In fatty acid analysis, there were not significantly differences in fatty acid composition among 10 cuts only except for C16:1n7, C20:3n6, and C20:4n6 (p>0.05).
