  • The principal objective of this study was to assess the effects of the addition of natural plant materials on the color and lipid oxidation of ground pork. Ground pork was blended with 0.3% (w/w) of cactus, fennel seed, orange peel, and rosemary, respectively, and stored for 8 days at $2^{\circ}C$. The pH, meat color, thiobarbituric acid reactive substances (TBARS) values, and metmyoglobin (MetMb) contents were measured. A gradual increase in pH was noted with increases in the storage time. The Hunter a (redness) value decreased until 6 days of storage, and evidenced no noticeable changes there after, and the cactus evidenced significantly higher a values than other groups over time (p<0.05). The TBARS formation was effectively inhibited by the addition of rosemary for 6 days of storage, reflective of strong antioxidative activity (p<0.05). The antioxidative activity on the lipid oxidation of cooked pork patties was noted in the following order: rosemary, fennel seed, cactus, and orange peel. The MetMb contents increased according to storage period, and no significant differences were noted among the meat patties.

  • 본 연구에서는 상용화 되고 있는 PCR 및 ELISA kit를 사용하여 국내에서 유통되고 있는 소, 돼지, 닭, 오리, 칠면조, 염소, 양, 말 등 8종의 식육, 혼합육, 그리고 식육가공품에 대하여 축종 감별능력을 평가하였다. 신선육에 대한 RAW meat ELISA kit$^{(R)}$의 검출한계는 축종별 함유율 0.20%~0.05% 이었고, 열처리 혼합육에서는 열처리 온도 및 시간, 그리고 축종별로 검출한계는 함유율 1.0%~0.05% 이하까지 다양한 차이를 나타내었다. 8종의 식육에 대한 축종별 감별력은 소 94.5%, 돼지 93.3%, 양 90.0%, 오리, 염소, 말, 칠면조 모두에서 100%를 나타내었다. Powercheck Animal Species ID PCR kit$^{TM}$의 경우에는 함유율 0.05%의 검출한계를 나타내었고 8종의 모든 축종에서 100%의 특이도를 나타내어 축종별 감별력이 우수한 것으로 나타났다. 또한, 햄, 소시지, 분쇄가공품, 식육추출가공품 등 총 60개 식육가공품에 대한 Cooked meat ELISA kit$^{(R)}$의 감별력은 햄(35.3%), 소시지(13.6%), 분쇄가공육(12.5%)의 순으로 나타났으며, 2종 이상의 혼합육에서는 상대적으로 낮은 감별력을 보여 제조과정에서 식육간 교차오염에 의한 혼입가능성이 있는 것으로 확인되었다. 쇠고기 육포 54개 제품에 대하여 다른 고기 혼입여부를 PCR Kit로 검사한 결과 13개 제품에서 돼지고기 유전자가 검출되었지만 ELISA Kit에서는 모두 음성으로 나타났다. PCR 양성 시료의 제조공정 중 교차오염 여부를 조사한 결과, 텀블러, 채반, 절단기, 건조기가 쇠고기 및 돼지고기 육포 생산라인에 동일하게 사용되어 교차오염에 의한 혼입으로 추정되었다. 종교적 이유 및 일부 특정 육류에 대한 알러지 반응 등 식품안전 확보차원에서 제품의 원재료의 올바른 표시와 식육간 교차오염이 발생되지 않도록 철저한 품질관리가 되어야 할 것으로 판단된다.

  • Antimicrobial stability of grape seed extract ($ActiVin^{TM}$), pine bark extract ($Pycnogenol^{(R)}$), and oleoresin rosemary ($Herbalox^{(R)}$) on the growth of Aeromonas hydrophila was investigated in cooked ground beef. When compared to the control, the populations of A. hydrophila were most effectively reduced by 4.06 log CFU/g for 1% $Pycnogenol^{(R)}$ added after cooking at 10 days of refrigerated storage, followed by 3.06 log CFU/g for 1% $Pycnogenol^{(R)}$ added before cooking and 1.36 log CFU/g for $ActiVin^{TM}$. Bacteriostatic and bactericidal activities were observed for $Pycnogenol^{(R)}$ added before and after cooking, respectively. $Pycnogenol^{(R)}$ consists of heat-labile and heat-stable compounds. $ActiVin^{TM}$ and $Pycnogenol^{(R)}$ could be considered for use as multifunctional preservatives in meat and meat products.

  • The aim of this study was to identify the optimal and superior type of natural calcium for replacing phosphate in cooked ground pork products. To achieve this, 0.5% eggshell calcium (ESC), oyster shell calcium (OSC), marine algae calcium (MAC), or milk calcium (MC) was added to ground pork meat products. The effect of this substitution was studied by comparing the substituted products with products containing 0.3% phosphate blend (control). ESC was considered an ideal phosphate replacer for minimizing the cooking loss, which likely resulted from the increase in the pH of the product. Among the other natural calcium types, OSC treatment did not cause a significant increase in pH, but it lowered the cooking loss. CIE $L^*$ values were higher (p<0.05) in products treated with OSC or MC than the control, and lowest (p<0.05) in the products with ESC. However, products with ESC had higher (p<0.05) CIE $a^*$ and CIE $b^*$ values than the control and products treated with other powders. Compared to the control, products treated with ESC and OSC had similar substitution effects on the textural properties of the products. Therefore, the results of this study suggested that the combined use of ESC and OSC could be a potentially effective method for replacing synthetic phosphate in ground pork products.

  • 오늘날 고기 소비가 증가하면서 소비자들은 평범한 식품보다는 질병의 예방 또는 치료 효과가 있는 기능성 식품성분을 요구하게 되었다. 본 연구의 목적은 불고기 양념에 분쇄한 인삼세근을 첨가량에 따라 0%, 0.5%, 1.0%과 2.0%수준으로 첨가하여 돈육 인삼불고기제품을 개발한 다음 인삼첨가수준에 따른 이화학적 및 관능적 제품특성을 무첨가구와 비교하고자 실시하였다. CIE로 측정한 육색에 있어서는 인삼 첨가비율이 증가할수록L값과 b값이 증가하는 경향을 나타내었다. 인삼이 첨가되지 않은 처리구와 비교하여 인삼이 첨가된 처리구의 연도가 낮게 나타났으나 응집성, 탄력성 및 씹힘성에서는 유의적인 차이가 없었다. 관능 평가 결과 인삼첨가 농도가 높은 처리구가 기호도가 더 높은 것으로 나타났다. 가열 조리한 다음 5$^{\circ}C$에서 7일간 냉장 저장하면서 산화도를 측정한 결과 인삼 첨가구가 저장 기간이 증가할수록 무첨가구와 비교하여 낮은 TBA 값을 나타냈다. 지방산 조성은 인삼 2% 첨가한 처리구가 PUFA/SFA 비율이 높게 나타났다. 결론적으로 돈육 불고기 제품에 인삼을 첨가함으로서 육질에 크게 영향을 주지 않으면서 향과 기호도를 증진시켜 일반돈육제품과 차별화된 제품이 될 수 있을 것으로 기대된다. 따라서 본 연구에서 개발한 인삼불고기 돈육가공제품은 우리 나라에서 생산되는 인삼과 국내 비선호부위인 돈육의 전지 및 후지를 적절하게 이용한 것으로서 국제시장에서 돈육 수출 및 소비 확대에 기여할 수 있을 것으로 기대된다.

  • This study aimed to investigate the combined effect of using natural calcium mixtures and various binding ingredients as replacers for synthetic phosphate in ground pork products. We performed seven treatments: control (0.3% phosphate blend), treatment 1 (0.5% natural calcium mixtures [NCM, which comprised 0.2% oyster shell calcium and 0.3% egg shell calcium powder] and 0.25% egg white powder), treatment 2 (0.5% NCM and 0.25% whey protein concentrate), treatment 3 (0.5% NCM and 0.25% concentrated soybean protein), treatment 4 (0.5% NCM and 0.25% isolated soybean protein), treatment 5 (0.5% NCM and 0.25% carrageenan), and treatment 6 (0.5% NCM and 0.25% collagen powder). All the treatment mixtures had higher pH and lower cooking loss than the control, which was treated with phosphate. We found that NCM and binding ingredients had no negative effects on the moisture content, lightness, and yellowness of the cooked ground pork products. Treatments 3 and 4 showed significantly lower CIE $a^*$ values than the control. Treatments 2 and 6 improved the textural properties of the products. In conclusion, the combination of NCM with whey protein concentrate or collagen powder could be suitable for producing phosphate-free meat products.

  • This study investigated the effects of the addition levels of white kimchi powder and acerola juice powder, as natural sources of sodium nitrite and sodium ascorbate, on the quality of cooked ground pork products. Freeze-dried white kimchi powder was prepared and used after fermentation for 2 wk. Six treatments were included: control (100 ppm sodium nitrite and 500 ppm sodium ascorbate), treatment 1 (0.2% white kimchi powder, 0.02 % starter culture, and 0.1% acerola juice powder), treatment 2 (0.2% white kimchi powder, 0.02% starter culture, and 0.2% acerola juice powder), treatment 3 (0.4% white kimchi powder, 0.04% starter culture, and 0.1% acerola juice powder), treatment 4 (0.4% white kimchi powder, 0.04% starter culture, and 0.2% acerola juice powder), and treatment 5 (0.4% celery powder, 0.04% starter culture, and 0.2% acerola juice powder). The pH values were decreased (p<0.05) because of lower pH of acerola juice powder, resulting in lower cooking yields (p<0.05) in these treatments. CIE L* and CIE a* values of indirectly cured meat products were not different (p>0.05) from the sodium nitrite-added control. However, indirectly cured meat products showed lower (p<0.05) residual nitrite contents, but higher (p<0.05) nitrosyl hemochrome contents and cure efficiency than the control. Treatments 2 and 4 had higher (p<0.05) total pigment contents and lipid oxidation than the control. This study indicates that white kimchi powder coupled with acerola juice powder has substantial potential to substitute synthetic nitrite to naturally cured meat products, which could be favored by consumers seeking clean label products.

  • Rabbits (48) of Soviet chinchilla (24) and White giant (24) were fed from 6 weeks to 12 weeks of age intensively on either of four isonitrogenous - isocaloric diets containing 0 ($D_1$), 5($D_2$), 10($D_3$) and 20($D_4$) percent raw neem seed kernel cake (NSKC), respectively as per NRC (1977) requirements in a Randomized block design and slaughtered at the end to find out differences in their carcass traits due to NSKC feeding. Dietary treatment had no significant effect on weight of edibles and inedibles and their percentages and dressing percentage in terms of carcass, carcass with pluck and carcass with pluck and head. Similarly, the meat-bone ratio of various primal cuts and overall carcass, yield of edibles per unit of inedibles and eye muscle area were not influenced due to the dietary variations. Chemical composition of fresh meat, and organoleptic evaluation of cooked meat with and without salt did not vary significantly due to incorporation of NSKC in the diets. The rabbits fed 20% NSKC ($D_4$) though consumed more (p<0.05) DM and DE per kg meat production, the intake of crude protein and total digestible nutrients was similar with other dietary treatments. Feed cost per unit meat production was, however, lower on 5 and 10% NSKC containing diets by 7.75 and 12.56%, respectively, as compared to deoiled ground nut cake containing control diet. It appears that NSKC could be used as a wholesome vegetable protein supplement upto 10% in diet of rabbits without any adverse effect on commercial carcass traits.
