In order to find a way of utilization of PSE park which has low water-holding capacity and inferior other functional properties, chemical, functional and microbiological characteristics of preblends were investigated during cooler and freezer storage after preblends were prepared using pre-and post-rigor PSE pork. The results obtained are summarized as follows. 1. With pre-rigor preblends, higher pH was maintained, and salt-extractability of protein and emulsifying capacity (EC) were improved. 2. TBA value and total plate count (TPC) were higher in the case of pre-rigor preblends, but the preblends can be used as raw material even at 20 days of cooler storage, in this period it still showed 0.768 of TBA value and 10^5 of TPC. 3. With the increase of salt level, salt-extractability of protein and EC were improved in pre-rigor preblends whereas not changed in post-rigor preblends. 4. During the freezer storage of pre-rigor preblends, salt-extractability of protein and EC were maintained high upto 4 weeks of storage while TBA and TPC were kept little changed. The increase in TPC during storage was slow regardless of rigor state of pork, and TPC was around 10⁴ at 4 weeks of sl:orage. Accordingly, PSE pork preblenda could be utilized as raw material upto this period. 5. According to the results obtained from this study, it appeared that PSE pork could have similar functional properties to those of normal pork if pre-rigor preblends are prepared.

부산물 대체가 재구성 돈육 품질에 미치는 영향

이무하(Moo Ha Lee),진상근(Sang Keun Jin) 한국축산학회 1987 한국축산학회지 Vol.29 No.3

The effects of the substitution of pork by by-products (liver, lung, tongue and spleen) at 7.5, 15, 22.5 and 30% of pork weight were evaluated on the quality of a restructured product. Increasing the substitution level, pH was increased in three by-product groups except in the product containing liver. In a product containing lung, as the substitution level increased, water holding capacity was decreased and thereby cooking loss was increased. TBA value also was increased. Color of products was improved with the substitution by three by-products except tongue. Flavor was negatively affected by the substitution up to 30% level. However, as the substitution level increased, tenderness was not adversely affected in three by-product groups except in the case of a product containing lung. Consequently, the maximum levels of the substitution without the impairement of the product quality were 22.5% for liver, lung and tongue, and 15% for spleen.

Preblends were prepared with pre-rigor and post-rigor state pork. Chemical, functional and microbial characteristics of the preblends were studied with time and temperature of storage. Emulsion-type sausages were manufactured using the preblends and quality attributes were investigated. Results obtained are summarized as follows: 1. In the case of cooler storage, total plate count (TPC), pH and TBA values of the preblends increased with time. Salt-extractable protein (SEP), emulsifying capacity (EC) and water-binding capacity (WBC) did not not show much changes, and the state of rigor did not make much difference even though pre-rigor preblends tended to have higher values. With the increase of salf added, the inhibitory effect of microbial growth increased, and SEP, EC and WBC were improved while TBA values increased. 2. With the freezer storage, TPC, pH and TBA values of the preblends were kept little changed. SEP was lower than in the cooler storage, especially significant difference was observed with post-rigor preblends. The effect of salt level on the functional attributes was similar to that in the cooler storage. 3. Emulsion stability of sausage emulsion manufactured with the preblends was deteriorated with storage time of preblends, especially the trend was worse in samples prepared with post-rigor preblends. TBA values increased drastically after 20 days of storage. With sausages prepared from freezer-stored preblends, changes of functional attributes showed a similar trends to those with cooler-stored preblends. 4. Considering results obtained from the study, pork preblends can be utilized as raw materials for sausage preparation regardless of rigor state of pork upto 20 days of storage in the case of cooler storage, and 12 weeks for freezer storage.

During the 1970s, concern arose that cured meats contained high levels of residual nitrite and preformed nitrosamines. Therefore, the search for alternatives and alternative approaches to the use of nitrite have been still continued, however no complete alternative for nitrite has yet been identified. Recently, it was publicized in Korea that nitrite-containing meat products would be detrimental to health, about which consumers have been seriously concerned. Therefore, this study was carried out to inform the consumer of the safety status of nitrite and thereby to lead proper consumption of meat products. For assessing the safety of nitrite, data regarding the regulation for use, metabolism in human body, and dietary intake amounts of nitrite were collected and analyzed. The mean intake level of nitrite for Korean per capita was recently reported to be not more than 1% of ADI set by JECFA. On the contrary, a calculation indicated that the daily nitrite intake per capita from saliva by ingestion of vegetables in Korea would be about 300-fold higher than that from cured meats. In consideration of the low consumption amount of meat products per capita of Korean, that is, at least one fifth, compared to European and American, there is no particular reason to concern about the impairment of health by nitrite intake from meat products for Korean. However, any effort for the reduction of residual nitrite content in cured meats should be given with an idea to minimize the intake of nitrite even from the minor source.

본 연구는 비타민 E 및 한방부산물을 함유한 항생물질(T1), 비타민 E 및 한방부산물 함유 허브추출물(0.03%, T2) 그리고 비타민 E 함유 한방부산물 함유 효소제(0.1% aminolevulinic acid, T3)의 급여가 거세돈육의 일당증체량과 사료요구율등의 생산성 및 식육의 육질에 미치는 영향에 대해 연구하여 이들 처리 물질들의 항생제 대체물질로서의 가능성에 대해 연구하였다. 허브추출물 처리군(T2)의 일당증체량이 가장 좋은 결과를 나타내었으나, 일당증체량 및 사료요구율에 있어 대조구와 유의적인 차이를 나타내지 않았다. 혈청 총 콜레스테롤 및 LDL-콜레스테롤 함량의 경우 T2 처리군이 대조군보다 낮은 함량을 나타내었으며(각각 114.71과 68.09 mg/dL), 한약부산물과 비타민E의의 처리가 HDL-콜레스테롤을 높였으며, LDL-콜레스테롤을 낮추었다. 비타민을 첨가한 처리군 T1, T2 그리고 T3의 근육내 비타민의 함량이 대조군 보다 유의적으로 높게 나타났다(각각 2.11, 2.21 and 2.18 mg/kg). 잔류 항생물질의 경우 대조군에서는 chlortetracycline이 0.08 ppm이 검출되었으나 처리군에서는 검출되지 않았다. TBARS와 VBN 함량은 T2 처리군(각각 0.06 mg MA/kg과 11.21 mg%)과 T3 처리군(각각 0.05 mg MA/kg과 8.23 mg%)이 대조군보다 유의적으로 낮게 나타났다. 하지만 가열감량 및 드립감량은 대조군과 처리군과의 유의적인 차이가 나타나지 않았다. This study was carried out to know the effect of the oriental medicinal plants byproduct containing vitamin E and 0.1% antibiotics (T1) and the oriental medicinal plants byproduct containing vitamin E and the replacing antibiotics by 0.03% herb extracts (T2) and 0.1% aminolevulinic acid (T3) on production performance of finishing hog and its meat qualities. There were no significant differences in the daily weight gain, feed intake, and feed conversion rate values between all treatment groups. However, the T2 group tends to have a higher daily weight gain (g/day) than the other groups (p>0.05). The T2 group showed lower total-cholesterol and LDL-cholesterol contents (114.71 and 68.09 mg/dl, respectively) than the control in the blood serum (p<0.001), and all the treated groups of oriental medicinal plants byproduct and vitamin E increased HDL-cholesterol and decreased LDL-cholesterol contents in the blood serum. Content of vitamin E in muscles from the group T1, T2 and T3 (2.11, 2.21 and 2.18 mg $kg^{-1}$, respectively) showed higher levels than those of control. The presence of antibiotics (chlortetracycline) in hog loin meat were detected (0.08 ppm) in control sample. However, there was no antibiotic in other treated hog loin meats (T1, T2 and T3, respectively). The thiobarbituric acid reactive substances and volatile basic nitrogen values of the groups T2 (0.06 mg MA $kg^{-1}$ and 11.21 mg%, respectively) and T3 (0.05 mg MA $kg^{-1}$ and 8.23 mg%, respectively) were significantly (p<0.05) lower than that of control in loin meat. However, there was no significant difference between treated samples (T1, T2 and T3, respectively) and control in cooking loss and drip loss.

본 연구는 3종의 식품 첨가제 미함유 그릴 돈육 햄 제품(T1; 등심, T2; 안심, T3; 뒷다리)에 대한 물리화학적, 미생물학적 및 관능적 품질특성의 변화를 조사하고자 실시하였다. 제품 제조 시 열처리는 그릴러에서 $60^\circC$ 30분간 저온가열, $150^\circC$ 50분간 고온가열 총 80분간 실시하였으며, 방냉 후 PA/PE 필름에 넣고 진공 포장하여 $4\pm$$1^\circC$에서 40일 저장하였다. pH 범위는 저장 초기 5.92(T1)~6.10(T3) 에서 저장 말기 6.28(T1)~6.60(T3)의 범위였다. 보수력은 T1은 85.99~93.24 %, T2 는 85.26~93.89%, T3는 89.11~94.67% 범위를 보였으며, T3가 다소 높은 경향이었다. 전단가는 T3 제품들이 전 저장기간 동안 높은 값을 나타내었다(p<0.05). TBARS와 VBN은 T2가 다른 처리구들보다 유의적으로 높았다(p< 0.05). 저장 40일까지 총 균수와 유산균수는 각각 1.93~3.48, 1.74~3.48 log10 CFU/g 수준으로 매우 양호한 편으로 $4\pm$$1^{\circ}C$에 보관 시 저장 40일까지 안전성을 확보하고 있었으며, 또한 저장 40일까지 전체적인 기호성이 5.0 이상을 유지하여 상품화 가능성이 입증되었다. The objective of this study was to investigate the physicochemical, microbiological and sensory properties of food additive-free grilled pork products manufactured using loin (T1), tender loin (T2) and ham (T3). The samples were heated for 30 min at $60^\circC$, and then 50 min for $150^\circC$. After cooling, vacuum packaged grilled pork samples was stored at $4\pm$$1^\circC$ for 40 days. The pH values of grilled pork samples ranged from 5.92 (T1) to 6.10 (T3) at the initial storage time, and from 6.28 (T1) to 6.60 (T3) after 40 days. The water holding capacities (%) was 85.99~93.24% for T1, 85.26~93.89% for T2 and 89.11~94.67% for T3, all of which were slightly higher than those of other pork products. The shear force values of T2 were significantly higher (p<0.05) than those of the other pork products throughout the storage period. The TBARS and VBN values of T2 were significantly higher (p<0.05) than those of T1 and T3. With regard to microorganisms, all grilled pork samples was in good condition, showing 1.93~3.48 log10 CFU/g via total plate counts, and 1.74~3.48 log10 CFU/g for lactic acid bacteria throughout the storage period. Regarding sensory evaluation, the scores of overall acceptability in all products were above 5.0 points through 40 days of storage.

김일석,민중석,이상옥,장애라,김동훈,진상근,이무하,Kim Il-Suk,Min Joong-Seok,Lee Sang-Ok,Jang Aera,Kim Dong-Hoon,Jin Sang-Kuen,Lee Mooha 한국축산식품학회 2004 한국축산식품학회지 Vol.24 No.4

본 연구는 국내산 냉동 및 냉장 등심의 가공조건을 달리하여 Pork cutlet를 제조하고 물리적 및 관능적 품질 특성을 비교하여 국내에서 비선호 부위인 냉동 등심의 외식용으로서의 소비 확대를 꾀하고자 수행되었다. Pork cutlet원료용 돼지고기 등심은 냉장육(T1), 염지 및 마사징처리 냉장육(T2), 염지 및 마사징처리 냉동육(T3), 냉동육(T4), 마사징처리 냉동육(T5)으로 처리조건을 달리한 후 Pork cutlet를 제조하여 물리적 및 관능적 품질특성을 평가하였다. 보수력 측정 결과, 모든 처리구간에 유의적인 차이는 없었다. 냉장육인 경우에, 염지와 마사징 처 리(T2)가 무처리구(T2)에 비해 다소 높게 나타났다. 처리구간 T4가 가장 낮은 보수력을 나타내었다. 육색 측정 결과 냉장육의 경우 처리구간 L$^{*}$ 값, a$^{*}$ 값 및 b$^{*}$ 값 모두 유의적인 차이가 없었다. 냉동육인 경우 L$^{*}$ 값은 T3 및 T5 처리구가 T4 처리구보다 높았고, b$^{*}$ 값은 T5 처리구가 유의적으로 높게 나타났으나(p<0.001), a$^{*}$ 값은 모든 처리구간에서 유의적인 차이가 없었다. 냉동육을 염지와 맛사징한 등심을 이용하여 제조한 T3 처리구의 Pork cutlet이 가장 낮은 전단력을 보여 상대적으로 가장 연도가 우수하였고(p<0.001), 무처리된 냉동육을 이용한 T4 처리구의 Pork cutlet이 가장 높게 나타났다. 밀가루 반죽과 고기 표면과 분리율은 T4처리구에서 유의적으로 높게 나타났다(p<0.001). 식별강도는 T1 : T3조합에서 가장 높게 나타났고, 척도묘사분석의 결과 전체적인 기호도는 유의적으로 가장 낮게 평가된 T4 처리구를 제외한 전 처리구간에서의 유의적인 차이가 없었다. 이상의 결과에서 냉동육만으로 pork cutlet를 제조하면 냉장육으로 제조한 pork cutlet와 물리적 및 관능적 특성에서 큰 차이를 보이므로 냉동육을 염지하거나 맛사징 처리하여 pork cutlet를 제조하면 냉동 돈육 등심의 소비 촉진에 기여할 수 있다고 판단되었다. The objective of the present study was to investigate the effect of processing conditions on the physical and sensory properties of pork cutlet produced from chilled pork loin (T1), the cured and massaged chilled pork loin (T2), the cured and massaged frozen pork loin (T3), frozen pork loin (T4), massaged frozen pork loin (T5). Water holding capacity (WHC) of pork cutlets were not significantly different among the treatments. In chilled pork loin, WHC of T2 were slightly higher than that of T1. T4 showed the lowest WHC among all treatment group. In meat color, CIE L$\^$*/, a$\^$*/. b$\^$*/ values in chilled pork loin were not significantly different between T1 and T2. L$\^$*/ values of T3 and T5 were higher than that of T4. a$\^$*/ values were not significantly different among the all treatments. T3 produced through the curing and massaging treatment showed the highest tenderness in shear force (p< 0.001), while force value (kg/㎤) of T4 were the highest among all treatments. Separation ratio of wheat dough from pork cutlet was highest (p.<0.001) in T4. In triangle test, T1 : T3 combination was higher than that of other pairs. No differences in acceptability of sensory evaluation were observed among T1, T2, T3, and T5 groups, while the frozen pork showed the lowest (p<0.001) acceptability. In conclusion, pork cutlets from T4 with the curing and/or massaging process showed similar acceptance than those from chilled pork loins, and this treatments may contribute to promote the consumption of frozen pork loins.
