Abstract

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.

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.
