김동청 ( Dong Chung Kim ),원선임 ( Sun Im Won ),인만진 ( Man-jin In ) 한국응용생명화학회 2017 Journal of Applied Biological Chemistry (J. Appl. Vol.60 No.1
사골로부터 칼슘과 인의 용출량을 증가시킴과 동시에 칼슘의 흡수에 효과적인 비율로 칼슘과 인의 함량을 조절하기 위하여 초산과 구연산의 혼합효과를 조사하였다. 사골에 구연산과 초산을 각각 첨가하여 추출물을 제조한 결과, 구연산은 사골로부터 칼슘과 인을 유사하게 용출시키나, 초산은 인보다 칼슘을 선택적으로 용출시켰다. 초산 0.2 %와 구연산 0.1 %를 혼합하여 제조한 추출물은 초산 0.2 %의 결과에 비하여 칼슘의 용출량은 약 30 %(26.89→34.22 mg) 증가하였으나 인의 용출량은 약 400 %(3.57→18.45 mg) 증가하였으며, 칼슘과 인의 비율은 7.53에서 1.85로 크게 개선되었다. 관능평가에서 맛과 전체적인 기호도는 0.2 % 초산+0.1 % 구연산을 첨가하여 제조한 시료가 증류수와 0.2 % 초산을 사용한 시료보다 우수하였다. This study was conducted to investigate the effect of acetic acid and citric acid treatments on amount and content ratio of calcium (Ca) and phosphorus (P) which were extracted from beef shank bones. The amount of Ca in shank bone extracts significantly increased with increasing citric acid and acetic acid concentration, whereas the amount of P increased with only adding citric acid to extraction media. In the case of combined treatment with 0.2 % acetic acid and 0.1 % citric acid, the amounts of Ca and P increased to 30 and 400 %, respectively and Ca and P ratio were drastically improved from 7.53 to 1.85 compared with treatment of 0.2 % acetic acid. The sensory score of shank bone extract prepared with 0.2 % acetic acid and 0.1 % citric acid treatment showed the highest values in taste and overall acceptability among the tested shank bone extracts.

This study was conducted to investigate the effect of different maturity scores [2 (bull), 2 (steer), 3-9 (cow)] and the number of extractions on water extract from Hanwoo shank bones (arm, fore shank, round and hind shank) with regard to sensory traits (white color, aroma, taste, overall acceptability). The white color of water extract from Hanwoo shank bones of maturity score 2 (bull and steer) was lighter than with maturity scores of 3-9 (cow) (p<0.05). The aroma of water extract from Hanwoo shank bones of maturity score 2 (bull and steer) was stronger than with other maturity scores 3-9 (cow) except for maturity score 5 (p<0.05). The taste and overall acceptability of water extract from Hanwoo shank bones of maturity score 2 (bull and steer) were higher than with maturity scores of 3-9 (cow) (p<0.05). The white color, aroma, taste and overall acceptability of water extract from Hanwoo shank bones of all maturity scores significantly decreased as the number of extractions (from 2nd to 4th) increased (p<0.05). In conclusion, there were significant differences between maturity scores 2 and maturity scores 3-9 (cow) with regard to sensory traits. Further studies need to address whether different maturity scores affect the price of shank bones in the meat industry.

This study was conducted to investigate the effects of mixed bone and brisket meat on the quality characteristics and nutritional components of shank bone extract and rib extract from Hanwoo. The pH values were influenced by the raw bones, mixed bone, brisket meatand their interactions (p<0.05). The salinity, sugar content, turbidity, and essential amino acid values increased significantly with addition of mixed bone and brisket meat. All attributes of sensory evaluation score were the highest in T6 (Rib 500 g + Mixed bone 500 g +Brisket meat 400 g) (p<0.05). The mixed bone significantly increased the saturated fatty acids of shank bone extract (p<0.001). Thus,the addition of mixed bone and brisket meat had a positive effect on the quality and nutritional components in shank and rib extracts ofHanwoo cattle.

본 연구는 시중에 유통중인 한우 사골의 과학적인 거래기준을 제시하고자 성숙도 2(수소), 성숙도 2(거세), 성숙도 3-9(암소)의 한우 반도체 각 4두에서 사골(상완골, 전완골, 대퇴골, 하퇴골)을 구입하여 총 4회 추출한 사골 용출액의 탁도와 색도(명도), 콜라겐과 단백질 함량, 칼로리 및 콘드로이친 황산 함량을 분석하였다. 성숙도 2에 해당하는 한우 수소와 거세우 사골 용출액의 탁도와 명도가 성숙도 3부터 9에 해당하는 한우 암소 사골용출액 보다 유의적으로 높게 나타났다(p<0.05). 추출횟수에 따른 탁도와 명도의 변화는 전체 성숙도에서 2차 추출까지 증가하다가 이후 유의적으로 감소하였다(p<0.05). 성숙도 2에 해당하는 한우 수소와 거세우 사골 용출액의 콜라겐과 단백질 함량이 가장 높게 나타났다(p<0.05). 성숙도 2에 해당하는 한우 수소와 거세우 사골 용출액의 칼로리와 콘드로이친 황산 함량이 성숙도 3부터 9에 해당하는 한우 암소 사골용출액 보다 유의적으로 높게 나타났다(p<0.05). 또한 추출횟수에 따른 콘드로이친 황산 함량 변화는 전체 성숙도에서 추출횟수가 증가 할수록 유의적으로 감소하였다(p<0.05). 이상의 결과를 종합하면, 전체 실험항목에서 성숙도 2(수소와 거세우) 사골용출액과 성숙도 3-9(암소) 사골용출액 간에는 차이가 있었으나, 전체 성숙도에서의 차이는 뚜렷하게 나타나지 않아 성숙도가 사골거래기준으로 적합한지는 보완적인 연구가 추가적으로 수행되어야 할 것으로 사료된다. This study was conducted to investigate the effect of maturity scores [2 (bull), 2 (steer), 3-9 (cow)] and the number of extractions (up to 4 times) on the chemical properties of water extract from Hanwoo shank bones (arm, fore shank, round and hind shank). The turbidity, meat color (CIE L value), collagen, protein, caloric and chondroitin sulfate contents of samples were observed. The turbidity and lightness were higher for water extract of Hanwoo shank bones with a maturity score of 2 (bull and steer) than maturity scores of 3-9 (cow) (p<0.05). The turbidity and lightness of water extract from shank bones of all Hanwoo maturity scores significantly increased with the 1st and 2nd extractions, but significantly decreased with 3rd and 4th extractions (p<0.05). The collagen and protein contents were highest for water extract from Hanwoo shank bones of maturity score 2 (bull and steer) (p<0.05). The caloric and chondroitin sulfate contents were higher for water extract from Hanwoo shank bones of maturity score 2 (bull and steer) than maturity scores of 3-9 (cow) (p<0.05). As the number of extractions increased, the chondroitin sulfate content significantly decreased (p<0.05). Based on these results, differences correlating with maturity scores were found only with collagen and protein contents. Therefore, further studies should be considered to address whether different maturity scores affect the price of shank bones in the meat industry.

This study was conducted to develop calcium-fortified shank bone extract (SBE) and to determine the effect of adding calcium lactate on physico-chemical characteristics of SBE during cold storage. The following five experiment groups were used: Control (0%, no addition), T1 (0.05% calcium lactate), T2 (0.1% calcium lactate), T3 (0.5% calcium lactate), and T4 (1% calcium lactate). When the concentration of calcium lactate added to the SBE was increased, the pH, redness, and yellowness values were significantly reduced, whereas the salinity, sugar content, and turbidity of SBE were significantly increased. Sensory parameters such as aroma, flavor, and overall acceptability in the control, T1, and T2 had similar scores. The TBARS values of SBE was significantly increased when 1% of calcium lactate was added, and the VBN values of SBE with calcium lactate at day 7 were higher than that of control (p<0.05). However, the addition of calcium lactate showed an inhibition effect on the growth of total microbial counts in SBE until 4 d of storage. The calcium content of SBE was increased by the addition of calcium lactate in a dose-dependently manner. The proper addition level of calcium lactate in the SBE was determined to be 0.1%.
