  • The effect of fermented spinach extracts on color development in cured meats was investigated in this study. The pH values of raw cured meats without addition of fermented spinach extract or nitrite (negative control) were higher (p<0.05) than those added with fermented spinach extract. The pH values of raw and cooked cured meats in treatment groups were decreased with increasing addition levels of fermented spinach extract. The lightness and yellowness values of raw cured meats formulated with fermented spinach extract were higher (p<0.05) than those of the control groups (both positive and negative controls). The redness values of cooked cured meats were increased with increasing fermented spinach extract levels, whereas the yellowness values of cooked cured meats were decreased with increasing levels of fermented spinach extract. The lowest volatile basic nitrogen (VBN) and thiobarbituric acid reactive substances (TBARS) values were observed in the positive control group with addition of nitrite. TBARS values of cured meats added with fermented spinach extract were decreased with increasing levels of fermented spinach extract and VBN values of curing meat with 30% fermented spinach extract was lower than the other treatments. Total viable bacterial counts in cured meats added with fermented spinach extract ranged from 0.34-1.01 Log CFU/g. E. coli and coliform bacteria were not observed in any of the cured meats treated with fermented spinach extracts or nitrite. Residual nitrite contents in treatment groups were increased with increasing levels of fermented spinach extract added. These results demonstrated that fermented spinach could be added to meat products to improve own curing characteristics.

  • Synthetic nitrite imparts a reddish-pink color to meat and a distinct flavor to meat products, delays lipid oxidation, and inhibits microbial growth and pathogens. However, excessive intake of nitrite might result in the production of carcinogenic nitrosamine, which might increase the risk of cancer in humans. Therefore, we aimed to find an alternative natural colorant for pork sausages. Pork sausages were mixed with 0.014% sodium nitrite (NaNO2) alone (CON), without either NaNO2 or purple-fleshed sweet potato powder (PP; CON1), 0.5% PP alone (PP1), 1% PP (PP2) alone, 0.011% NaNO2 and 0.5% PP (SP1), and 0.011% NaNO2 and 1% PP (SP2). The sausages were then cooked and stored for physicochemical analysis on days 0, 5, 10, 15, and 20. The a* and W* values were the greatest and lowest in the SP2 and CON1 treatments, respectively (p < 0.05). The concentrations of residual nitrite in the sausages at 20 days decreased in the order of CON > SP1, SP2 > PP2 > PP1, CON1. The fatty acid content was higher, and flavorous amino acids were more in PP2 (p < 0.05). The fatty acid composition was comparable between the SP2 and CON groups, but the contents of glutamic acid and alanine were greater in the SP2 group. In conclusion, SP2 (0.011% NaNO2 with 1% PP) could be added as a natural colorant for pork sausage production, and NaNO2 could be substituted with up to 20% PP without detrimental effects on sausage appearance and/or quality.

  • 유화형 소시지에 마늘즙과 양파즙을 각각 1%와 3%를 첨가하여 냉장온도($4{\pm}1^{\circ}C$)에서 21일간 저장하면서 pH, peroxide value, TBARS, 총 미생물수 및 아질산염 잔존량을 조사하였다. 실험구는 마늘즙과 양파즙을 첨가하지 않은 대조구, 마늘즙 1% 첨가구는 T1, 마늘즙 3% 첨가구는 T2, 양파즙 1% 첨가구는 T3 및 양파즙 3% 첨가구를 T4 등 5개 처리구로 나누어 0, 7, 14 및 21일간 저장하면서 실험하였다. pH는 저장기간이 경과하면서 모든 처리구에서 서서히 감소하였고, 마늘즙 첨가구는 양파즙 첨가구보다 낮았으며, 대조구의 pH가 가장 높았다. 과산화물가는 저장기간 동안 증가하였고, 마늘즙과 양파즙의 첨가구는 대조구보다 유의적으로 낮은 함량을 보였다(p<0.05). TBARS는 저장기간 동안 직선적으로 증가하였으며, 마늘과 양파를 첨가한 유화형소시지는 대조구보다 낮아 마늘과 양파즙이 지방산화를 지연시켰고, 마늘이 양파보다 효과적이었다. 그리고 마늘즙과 양파즙의 첨가량이 많을수록 TBARS값은 낮은 경향이었다(p<005). 총 미생물수는 저장기간이 지나면서 모든 첨가구에서 증가하였고, 저장 0일에는 처리구간 유의성이 없었으며, 처리구간에는 마늘즙 3% 첨가구인 T2에서 유의적으로 낮은 미생물수를 나타내었다. 아질산염 잔존량은 저장기간이 경과하면서 감소하였는데 T2에서 다른 시험구보다 많이 감소하였다. 이상의 결과를 종합적으로 고찰해보면 마늘즙 3% 첨가구는 산화 및 미생물 성장 억제 가능성이 있는 것으로 사료된다.

  • 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.

  • This study investigated the nitrate reduction ability of Micrococcaceae on pigment formation in Chinese- style sausage. One hundred ppm sodium nitrite and 150 ppm sodium nitrate was added asepticly to ground pork which was then inoculated with $10^7CFU/g$ of either Micrococcus varians, Staphylococcus carnosus or Staphylococcus xylosus. All samples were cured at $20{^{\circ}C}$ or $30{^{\circ}C}$ for 3 days and then color, residue nitrite, nitrosyl pigment and residue nitrate were determined. The results indicated that samples inoculated with S. xylosus had higher a- and b- values due to nitrate reduction and pigment production after 3 days curing and these values were higher at the higher curing temperature. The nitrosyl pigment of the samples with S. xylosus had highest values after 3 days curing at both $20{^{\circ}C}$ and $30{^{\circ}C}$. However, sample inoculated with S. carnosus and S. xylosus had lower nitrate contents than the sample inoculated with M. varians. At $30{^{\circ}C}$ as well as S. carnosus and M. varians had a stronger decreasing in nitrate concentration during curing at $20{^{\circ}C}$. Moreover, samples inoculated with S. xylosus and S. carnosus had a higher residual nitrite content during curing at $20{^{\circ}C}$ or $30{^{\circ}C}$. In conclusion, two Staphylococci strains tested were most optimum starter cultures for improving pigment formation during Chinese-style sausage curing.

  • The objective of this study was to determine the effects of short-term presalting on pink color and pigment characteristics in ground chicken breasts after cooking. Four salt levels (0%, 1%, 2%, and 3%) were presalted and stored for 0 and 3 d prior to cooking. Cooking yield was increased as salt level was increased. However, no significant differences in pH values or oxidation reduction potential (ORP) of cooked chicken breasts were observed. Cooked products with more than 2% of salt level had less redder (lower CIE $a^*$ value) on day 3 than on those on day 0. As salt level was increased to 2%, myoglobin was denatured greatly. Myoglobin denaturation was leveled off when samples had 3% of salt. With increasing salt levels, residual nitrite contents were increased while nitrosyl hemochrome contents were decreased. These results demonstrate that salt addition to a level of more than 2% to ground meat may reduce the redness of cooked products and that presalting storage longer than 3 d should be employed to develop a natural pink color of ground chicken products when less than 1% salt is added to ground chicken meat.

  • 국내에서 런천미트라고 통칭되는 돈육통조림의 품질 비교를 위하여 시중에서 유통되는 4개국 8개회사의 제품 12가지를 분석하였다. 아질산염 함량은 제품간에 다양한 수준을 보여주었으나 모두 낮은 수준이었으며, 소디움은 한두개의 제품을 제외하고는 비슷한 수준이었다. 사용된 원료육의 품질비교를 위하여 콜라젠 함량과 총육색소 함량을 분석하고 전기영동으로 순수한 돈육과 비교하였다. 수입품에서는 런천미트와 chopped meat 사이에는 차이가 있었으며, 국내산에서는 대부분 비슷하였다. 수입품과 국내산 비교시에는 국내산은 콜라젠 함량이 수입품의 chopped meat와 비슷한 수준이었으나 총육색소 함량은 월등히 높았다. 전기영동상으로는 런천미트나 chopped meat 제품 혹은 기타제품 모두의 돈육함량을 정량적으로 비교하기가 매우 곤란한 것으로 보인다. 일반성분상으로는 국내산이나 수입품 모두 런천미트가 다른 제품보다 탄수화물 함량이 높고, 국내산 런천미트의 품질은 수입품 런천미트나 chopped meat 제품의 혼합상태로 판단된다. 따라서 국내에서도 런천미트라는 저가제품의 품질규격이 확립되어야 수입품과의 가격경쟁력을 가질 수 있을 것이다.
