This study was investigated the effect of aging at low temperature of seasoned pork with Korean traditional sauces. The samples, pork loins were cut by the shape of cube ($5{\times}15{\times}5\;cm$) and porks were seasoned with Korean tradition sauce such as soy sauce base (T1), red pepper sauce base (T2), and soybean sauce base (T3) in the same proportion of meat seasonings, respectively. The seasoned samples were stored, at $1{\pm}1^{\circ}C$ during 28 days. Surface meat color of seasoned pork was affected by the kind of sauces. Lightness of seasoned pork with soy sauce was decreased with increased in periods while red pepper sauce made it more red and soybean sauce produced a light seasoned pork, Lightness of inner meat color of seasoned pork was decreased with increased aging periods, and seasoned pork with soy sauce was lower compared to other treatments. TBARS of seasoned pork with soy sauce was lower compared to other treatments, and increased TBARS in all treatments with aging period. Total plate counts were increased with aging period, and those of seasoned pork with soy sauce were lower compared to other treatments. The microbial counts of Escherichia coli levels in all treatments was higher at the first day of aging periods. However Escherichia coli levels were decreased with increasing the aging period. Lactobacilli spp. of seasoned pork with soy sauce was not increased during aging periods, whereas other treatments were increased with aging period increased. 한국 전통 장류를 이용한 양념 돈육의 저장 안정성에 관한 연구로 돼지고기의 등심을 채취하여 $5{\times}15{\times}5\;cm$ 크기로 자른 후 육을 동일한 비율의 양념액에 침지하여 $1{\pm}1^{\circ}C$에서 28일간 숙성하면서 양념육(간장소스 양념육, T1; 고추장소스 양념육, T2; 된장소스 양념육, T3)의 품질 특성을 조사하였다. 양념육의 표면 육색은 소스의 영향을 많이 받았으며 간장 소스로 양념한 돈육의 명도는 낮게, 고추장소스로 양념한 돈육의 적색도는 높게, 된장 소스로 양념한 돈육의 명도는 높게 나타났다. 심부 육색의 명도는 모든 처리구에서 숙성기간에 따라 감소하였으며, 간장 소스로 양념한 돈육에서는 낮게 나타났다. TBARS는 간장 소스로 양념한 돈육이 다른 처리구에 비해 낮게 나타났으며 전 숙성기간 동안 증가하였다. 총균수는 모든 처리구에서 숙성기간에 따라 증가하였으며 간장 소스로 양념한 처리구가 다른 처리구에 비해 전 숙성기간 동안 낮은 총균수를 나타내었다. 대장균 수는 숙성 초기 $2.7{\sim}3.27\;log_{10}CFU/g$으로 다소 높게 나타났으나 숙성기간의 증가에 따라 처리구들에서 감소하였으며, 고추장 소스로 양념한 처리구는 숙성 14일에 된장소스로 양념한 처리구는 숙성 28일에 대장균이 나타나지 않았다. 유산균 수는 간장 소스로 양념한 처리구에서 숙성기간 동안 유산균수의 증가가 나타나지 않았으며, 고추장 소스로 양념한 처리구와 된장 소스로 양념한 처리구에서는 숙성기간에 따라 증가하였다.

Analyses were conducted to estimate carcass component of yield grade factors by sex and live weight class and to develop the prediction equation of retail product weight by sex in Korean native cattle (Hanwoo). Data from 42,113 Hanwoo carcasses were used to estimate the traits of yield grade factor and an additional 1,066 carcasses were used to develop the prediction equation of retail meat weight. The average of fasting weight of cow, bull and steer were 529 kg, 596 kg, and 634 kg respectively. Carcass weight (CW), backfat thickness (BFT), loineye area (REA), Index score of wholesale meat and yield grade were significantly (p<0.01) affected by sex and live weight. The lean meat percentage, fat percentage and bone percentage based on the weight of cold carcasses were significantly different (p<0.05) between sex groups. The equation of predicting the retail meat product from this study could be expressed as a multiple regression $Y=-4.18+0.63{\times}CW\;(kg)-0.17{\times}BFT\;(cm)+0.16{\times}REA\;(cm^2)$, $R^2=0.93$. Among the independent factors, the BFT was the highest contributor to the prediction equation. Using the equation from this study should allow for rapid, precise and cost-effective assessment of the retail product in Hanwoo beef carcasses.

This study was conducted to evaluate the quality attributes of cooked hams made with four hind leg muscles (Biceps femoris, Semimembranosus, Rectus femoris, Gluteus medius) and Longissimus dorsi. Muscles were prepared from three market-weighted crossbreeds ($L{\times}Y{\times}D$) and the pH, proximate chemical composition, color, texture attributes, and sensory properties of cooked pork muscle hams were evaluated. In the raw state, no significant differences in pH were found among the five muscle hams. However, Rectus femoris ham had the highest pH, while Longissimus dorsi ham had the lowest pH (p<0.05). All muscle hams had similar moisture, fat, and ash contents. The protein content (%) was highest in Longissimus dorsi ham (p<0.05). The Hunter L value was highest for Longissimus dorsi ham while Rectus femoris and Gluteus medius hams had the lowest Hunter L values (p<0.05). The Hunter a values were similar in Rectus femoris, Biceps femoris, and Gluteus medius hams, and lowest for Longissimus dorsi ham (p<0.05). Texture attributes were not significantly different among the five muscle hams (p>0.05). The results of sensory evaluation showed that Semimembranosus hams had the highest flavor score, but there were no significant differences among five muscle hams with regard to color, taste, and texture (p>0.05).

성필남,이종언,김진형,조수현,하경희,임동균,김동훈,이종문,고문석,Seong, Pil-Nam,Lee, Chong-Eon,Kim, Jin-Hyoung,Cho, Soo-Hyun,Hah, Kyoung-Hee,Lim, Dong-Gyun,Kim, Dong-Hoon,Lee, Jong-Moon,Ko, Moon-Suck 한국축산식품학회 2008 한국축산식품학회지 Vol.28 No.1

프레스햄의 원료육 중 말고기 함량을 0%, 50%, 100%로 증가시키면서 햄의 품질을 비교한 결과, 말고기의 특성이 프레스햄의 품질에 많은 영향을 미치는 것을 알 수 있었다. 특히, 말고기 함량이 높을수록 지방함량은 적었으며, 수분함량은 증가하는 경향을 보였다. 또한 말고기 100%로 제조된 프레스햄은 돼지고기 100%로 제조된 프레스햄 보다 제품색이 붉고, 어두운 특성을 보였으며, 햄의 탄력성도 말고기 100%로 제조된 프레스햄이 돼지고기 100%로 제조된 프레스햄보다 더 높았다. 하지만 말고기 100%로 제조된 프레스햄이 제품색과 전체기호도에서 돼지고기 햄보다 떨어지는 것으로 나타나 돼지고기 햄과 유의적인 차이를 나타내지 않은 말고기와 돼지고기를 반씩 넣은 햄을 이용한다면 말고기에 익숙하지 않은 국내 소비자들에게 대중화시킬 수 있을 것으로 보인다. 광물질 중 P의 함량은 말고기 100%로 제조된햄이 돼지고기 100%로 제조된 햄보다 낮았으나 Fe, Mn, Zn의 함량에서는 돼지고기 100%로 제조된 햄보다 함량이 높아 말고기 100%로 제조된 햄이 Na, Fe, Mn, Zn의 더 훌륭한 공급원이 될 것으로 사료된다. 이상의 결과를 종합하면 말고기 프레스햄은 돼지고기 햄과는 다른 품질적인 특성들을 나타내었으며, 최근 소비자의 건강지향성 등을 고려할 때 저지방, 미량 광물질 강화 등 기능성 프레스햄 제조가 가능할 것으로 판단된다.

The aim of this work was to analyze the effects of salt and $NaNO_2$ on weight loss, proximate compositions. chemical parameters and texture characteristics of dry-cured ham processed using Korean methods. Four different treatments were considered: The HS group of 3 hams (11.30 kg) was salted with 9.2 g/kg salt (w/w) (high salt batch), the HS+$NaNO_2$ group of 3 hams (10.65 kg) was salted same as HS group and added 100 ppm $NaNO_2$. The LS group of 3 hams (11.42 kg) was salted with 6.2 g/kg salt (w/w) (Low salt batch), the LS+$NaNO_2$ group of 3 hams (10.62 kg) was salted same as LS group and added 100 ppm $NaNO_2$. The highest weight losses took place at the drying stage (27.46, 28.25, 26.99, and 28.42%). However, there were no significant differences in the weight losses between treatments (p>0.05). The moisture content was significantly affected with addition of $NaNO_2$ (p<0.05), the LS hams had significantly higher moisture content than HS+$NaNO_2$ and LS+$NaNO_2$ (p<0.05). The level of salt and $NaNO_2$ did not affect the fat, protein and ash contents. The hardness and chewiness in biceps femoris muscle from LS hams were significantly lower than in the muscles from HS+$NaNO_2$ hams (p<0.05). The $NaNO_2$ did not affect the texture characteristics of dry-cured hams. The processing conditions significantly affected the chemical parameters of biceps femoris muscle (p<0.05). The water activity in biceps femoris muscle from LS hams was significantly higher than in muscles from HS and HS+$NaNO_2$ hams (p<0.05). The salt content in biceps femoris muscles from LS+$NaNO_2$ hams was significantly lower than in the muscles from HS and HS+$NaNO_2$ hams (p<0.05). The $NaNO_2$ treatment did not affect the $NaNO_2$ content in biceps femoris muscles (p>0.05). The processing conditions did not significantly affect the lightness (L), redness (a), and $h^{\circ}$ of biceps femoris muscles (p>0.05). The yellowness (b) and chroma in biceps femoris muscle from HS+$NaNO_2$ hams were significantly higher than in the muscles from HS and LS hams.
