본 연구는 쑥 분말 첨가와 도체 등급이 돈육 패티의 저장성에 미치는 영향을 검토하기 위하여, B 및 I 등급 원료육에 쑥 분말을 첨가한 것과 첨가하지 않은 것 네 종류의 돈육 패티를 제조하였다. 쑥 분말을 첨가한 돈육 패티의 아질산 잔류량은 저장 2주까지 큰 폭으로 감소하였으나, 첨가하지 않은 것은 4주까지 큰 폭으로 감소하여서 쑥 분말의 첨가가 아질산 잔류량에 영향을 미쳤다. 돈육 패티의 L＊값은 제조직후가 가장 높았으며, 쑥 분말을 첨가한 것이 낮았고, B등급 패티가 E 등급보다 높았다. 돈육 패티의 a＊값은 E 등급육이 B등급육보다 높았으며, 저장 중 변화는 없었고, b＊값은 B등급 육으로 제조한 패티가 E 등급육으로 제조한 것보다 높았다. 돈육 패티의 pH는 저장기간이 경과하면서 낮아졌다. VBN, TBARS 및 총균수는 저장기간에 따라 증가하였으며, 쑥 분말의 영향은 없었다.

This study investigated the effects of lemon extract powder and vinegar powder on the physicochemical and microbiological characteristics of pork sausages naturally cured using white kimchi powder during storage for 30 days. Six batches were included: control (0.01% sodium nitrite and 0.05% sodium ascorbate); treatment 1 (0.3% white kimchi powder and 0.5% lemon extract powder); treatment 2 (0.3% white kimchi powder and 1.0% lemon extract powder); treatment 3 (0.3% white kimchi powder and 0.5% vinegar powder); treatment 4 (0.3% white kimchi powder and 1.0% vinegar powder); and treatment 5 (0.3% white kimchi powder, 0.5% lemon extract powder, and 0.5% vinegar powder). Treatment 2 had significantly lower pH values and higher cooking loss than the other batches (p<0.05). Treatments 1, 2, and 5 had similar (p>0.05) CIE a^* as the control, while treatments 3 and 4 showed significantly lower values (p<0.05). The residual nitrite content in naturally cured products was lower than the control (p<0.05), while treatments 1 and 2 showed significantly higher nitrosyl hemochrome content and curing efficiency (p<0.05). TBARS values were similar for all treatments and the control (p>0.05). Treatments 1 and 2 showed significantly reduced aerobic plate counts (APC; p<0.05) than the control and other treatments. However, across all batches, TBARS values and APC significantly increased during storage (p<0.05). Our results suggest that lemon extract powder, rather than vinegar powder, may offer a promising alternative for supplementing the functions of nitrite in naturally cured sausages.

The impact of green tea extract powder and rosemary extract powder, alone or in combination, on the quality characteristics of naturally cured pork sausages produced with white kimchi powder as a nitrate source was evaluated. Ground pork sausages were assigned to one of seven treatments: control (0.01% sodium nitrite and 0.05% sodium ascorbate), treatment 1 (0.3% white kimchi powder and 0.05% green tea extract powder), treatment 2 (0.3% white kimchi powder and 0.1% green tea extract powder), treatment 3 (0.3% white kimchi powder and 0.05% rosemary extract powder), treatment 4 (0.3% white kimchi powder and 0.1% rosemary extract powder), treatment 5 (0.3% white kimchi powder, 0.05% green tea extract powder, and 0.05% rosemary extract powder), and treatment 6 (0.3% celery juice powder, 0.05% green tea extract powder, and 0.05% rosemary extract powder). Naturally cured products had lower (p<0.05) cooking yield and residual nitrite content than control sausages. However, compared to the control, naturally cured products with white kimchi powder (treatments 1 to 5) showed similar the pH, oxidation-reduction potential, CIE L^* values, CIE a^* values, nitrosyl hemochrome content, total pigment content, and curing efficiency to the control. When the amount of green tea extract powder or rosemary extract powder was increased to 0.1% (treatments 2 and 4), lipid oxidation was reduced (p<0.05). These results indicate that green tea extract powder, rosemary extract powder, and white kimchi powder may provide an effective solution to replace synthetic nitrite and ascorbate used in traditionally cured products.

본 연구는 유화형 돈육소시지 제조에 첨가되는 아질산염을 대체할 목적으로 천연색소로 알려진 레드비트 분말을 첨가하여 돈육소시지의 이화학적 특성에 미치는 영향에 대해 알아보고자 실시하였다. 총 5개의 처리구로 제조를 하였으며, C (아질산염 0.01%), T1 (아질산염 0.005% + 레드비트 분말 0.5%), T2 (아질산염 0.005% + 레드비트 분말 0.25%), T3 (레드비트 분말 0.5%), T4 (레드비트 분말 0.25%)로 처리하여 10±1℃에서 6주간 저장하면서 실험을 실시하였다. 명도는 Control이 유의적으로 높았고, 적색도는 T1이 높았으며, 황색도는 T3와 T4가 높았다. pH는 T3와 T4가 유의적으로 낮은 경향을 보였다. VBN은 처리구간별 유의적 차이가 없었다. DPPH 결과는 0주차에서 T1과 T3가 유의적으로 높은 경향을 보였으며, 2주차에서 T1이 높았고, 4주와 6주차에서는 T3가 높았다. 또한, 잔존아질산이온 결과는 Control이 저장 6주 동안 유의적으로 높았고, T3와 T4는 낮은 결과를 나타내었다. 따라서, 본 실험 결과에 의하면 레드비트 분말의 첨가는 유화형 돈육소시지의 품질을 감소시키지 않으면서 아질산염의 첨가를 줄일 수 있을 것으로 판단되었으며 항산화활성에 효과를 나타내는 것으로 사료되었다.

This study was conducted to determine the effects of NaCl concentration and cooking temperature on the color and pigment characteristics of presalted ground chicken breasts. Four treatments with different salt concentrations (0%, 1%, 2%, and 3%) were prepared and stored for 7 d prior to cooking. Each sample was cooked to four endpoint temperatures ($70^{\circ}C$, $75^{\circ}C$, $80^{\circ}C$, and $85^{\circ}C$). The salt concentration affected the color and pigment properties of the cooked ground chicken breasts. As the salt concentration increased, the cooking yield and residual nitrite content also increased. However, the samples with 1%, 2%, and 3% NaCl showed similar nitrosyl hemochrome and total pigment contents. Among the products containing salt, the samples with 3% NaCl showed the lowest percentage myoglobin denaturation (PMD) and the lowest CIE $a^*$ values. The cooking temperature had limited effects on the pigment properties of cooked ground chicken breasts. The oxidation-reduction potential and residual nitrite contents increased with cooking temperature, while the PMD, nitrosyl hemochrome, total pigment contents and CIE $a^*$ values were similar in the samples cooked at different temperatures. These results indicated that the addition of up to 2% salt to ground chicken breasts and storage for 7 d could cause the pink color defect of cooked products. However, the addition of 3% NaCl could reduce the redness of the cooked products.

The present study was carried out to develop sausage using Leuconostoc citreum which was isolated from Kimchi. Leuconostoc citreum was added to sausage at three concentrations of 1, 3 and $5\%$, and was stored at $10^{\circ}C$ for 40 days. The pH of the sausage containing Leuconostoc citreum was similar to the control group. The TBA value of the group containing Leuconostoc citreum was lower than the control group. However, the TBA value of the control group steadily increased after 10 days of storage, and there were only minor changes in the groups containing Leuconsostoc citreum. In addition, the TBA value of the sausages employed for the present study was either 0.46MA mg/kg or less than that over the entire period of storage. The residual nitrite value was 47.1 ppm at the beginning of the storage in the control group and was 32.5, 32.2 and 30.9 ppm in the groups containing Leuconostoc citreum. The sausages with TBA values higher than 70 ppm are not permitted in Korea. With regards totexture characteristics, it was observed the hardness was lower in the groups containing Leuconostoc ctireum than in the control group while springiness was almost the same in both the groups, but the group containing $1\%$ Leuconostoc citreum showed the best springiness. Both gumminess and brittleness were lower in the groups containing Leuconostoc citreumthan than in the control group. It was inferred that with an increase in the concentration of Leuconostoc citreum there was a decrease in the value of gumminess and brittleness. The results of the sensory evaluation were generally better in the groups containing Leuconostoc citreum than the control group. The sausage containing $3\%$ Leuconostoc citreum obtained the most excellent scores.

Objective: This study aimed to develop a value-added product concerning technological and sensory characteristics changes of the use of mechanically deboned poultry meat (MDPM) as meat replacer in lamb and mutton emulsion-type sausages (mortadella). Methods: Sausages were produced with lamb and mutton and with different contents of MDPM. Six treatments, using lamb or mutton and 0%, 30%, and 60% of MDPM in relation to the meat batter, were produced and analyzed for pH, proximal composition, calcium and residual nitrite content, water activity, 2-thiobarbituric acid reactive substances (TBARS), instrumental color and texture profile. The sensory profile of the mortadella's was also evaluated by acceptance test and check-all-that-applies (CATA) analysis. Results: The MDPM addition increased (p<0.05) fat, residual nitrite and calcium content in the all sausage formulations, but mutton sausage had (p<0.05) higher fat and lower moisture content than lamb sausage. The pH, water activity, TBARS index and color was not affected by MDPM additions, while the mutton sausages were significantly redder (higher $a^*$, $C^*$, and lower $h^{\circ}$) and darker (lower $L^*$) than lamb sausages. Adding up to 60% of MDPM reduced (p<0.05) sausages hardness and chewiness. Overall, the meat replacement by MDPM increased the sausages acceptance, but the mutton sausage with 30% of MDPM replacer were the most preferred. Consumers related that pink color, glossy appearance, poultry meat-like taste, soft texture, juicy and greasy mouth feel to all sausages contain MDPM according to CATA analysis. Conclusion: Mutton from culled ewes can be utilized for mortadella production with 30% replacement of lean mutton and fat by MDPM.
