미트로프 제품에 열풍건조 단감분말(HP)과 동결건조 단감분말(FP)을 각각 3%(HP-3%, FP-3%)와 6%(HP-6%, FP-6%)를 첨가하도, 무첨가구를 대조구로 제조한 후 함기포장하여 5℃에 저장하면서 품질평가를 실시하였다. 수분과 조회분은 FP-6%가 유의적으로 높았고(p<0.05), 조단백질 및 조지방은 모든 제품에서 유의적인 차이가 없었다(p>0.05). pH는 대조구가 처리구보다 높았으며(p<0.05), 처리구간에서는 차이가 없었다(p>0.05). 모든 제품에서 저장기간이 경과함에 따라 TBARS값은 증가하는 경향이었으며, 처리구들 간에서는 HP-6%와 FP-6%가 유의적으로 높게 나타났다(p<0.05). 각 소재물들의 첨가비율이 높을수록 높은 TBARS와 적색도는 증가하였다. 미생물 분석결과 저장 전 기간 동안 모든 제품에서 총균수는 3.11 log10 CFU/g를 유지하여 양호하였다. 전체적인 기호도는 대조구에 비해 처리구들이 더 좋았고 첨가량에 의한 차이는 없었다(p>0.05). 이상의 결과로써 다양한 생리활성물질을 가지는 열풍 또는 동결건조 단감분말은 기능성 식품의 소재로써 미트패티류 제품에 적용할 수 있음을 확인하였다.
Four different pork loaves were made with two levels, HP/FP-3% and HP/FP-6%, containing 3.0 and 6.0% HP(hot air dried sweet persimmon powder)/FP(freezer dried sweet persimmon powder), respectively. HP and FP(3% and 6%) were added into ground pork loin separately. A control without persimmon powder were used for comparison. Patties were cooked to 74℃ in electric oven, after cooling, the aerobic packaged meat loaves were stored at 5℃. The moisture and crude ash were higher in the FP-6%, and the crude protein and crude fat were no different among the samples. The pH in control sample was significantly higher(p<0.05) than those of treatment group, however no significant difference was found among the 4 treatments. The TBARS(thiobarbituric reactive substance) values of all samples showed a tendency of increasing value along the storage days. The TBARS and a* value increased(p<0.05) as the addition ratio of HP/FP increased, respectively. With regard to microorganisms, the number of total aerobic bacteria were lower than 3.11 log10 CFU/g. In sensory evaluation, meat loaves containing persimmon powder resulted in a high overall acceptability, although they were not significantly different in overall acceptability.
