본 연구는 동물성지방 대체물질로서 홍화씨(Carthamus tinctorius L.)의 첨가가 분쇄돈육의 이화학적 품질특성에 미치는 영향을 검토하였다. 분쇄돈육은 돈육등심 68%, 냉수 10%, 소금 2%에 돼지지방 20%(control), 돼지지방 10%와 홍화씨 10%(10% SS) 그리고 홍화씨 20%(20% SS)를 첨가하여 제조하였다. 생육 및 가열육의 수분, 단백질 및 회분함량은 20% SS가 가장 높았고, 지방함량은 대조군이 가장 높았다(p<0.05). 수율, 수분보유율, 지방보유율 및 보수력은 20% SS가 가장 높았으며, 직경감소율은 대조군이 가장 높았다. 외부 및 내부의 명도(L-value), 적색도(a-value) 및 황색도(b-value)는 대조군이 10% SS 및 20% SS보다 유의하게 높았다(p<0.05). 콜레스테롤 함량은 대조군, 10% SS 및 20% SS가 각각 50.85, 21.77 및 17.91 mg/100 g으로 20% SS가 가장 낮았다(p<0.05). Linoleic acid 함량은 대조군, 10% SS 및 20% SS가 각각 28.68%, 41.04% 및 54.26%이었다. 전체 불포화지방산 함량은 대조군, 10% SS 및 20% SS가 각각 50.53%, 55.76% 및 64.93%이었다. 지방산 조성에서 linoleic acid 및 전체 불포화지방산 함량은 20% SS가 가장 높았다(p<0.05). 아미노산 조성은 시료들 사이에 유의한 차이가 없었다.
This study was carried out to investigate the effect of the addition of safflower seed (Carthamus tinctorius L.) on the physicochemical properties of ground pork as an animal fat replacer. Three types of ground pork were evaluated: 20% pork fat added (control), 10% pork fat and 10% safflower seed powder added (10% SS), and 20% safflower seed powder added (20% SS). The moisture, protein, and ash contents were highest in 20% SS, and the fat content was highest in the control (p<0.05). The cooking yield, moisture retention, fat retention, and water-holding capacity were highest in 20% SS, and the control showed a reduction in the diameter (p<0.05). The external and internal L-, a-, and b-values of the control were higher than those of the 10% SS and the 20% SS (p<0.05). The cholesterol content of the control, the 10% SS, and the 20% SS was 50.85, 21.77, and 17.91 mg/100 g, respectively, and that of the 20% SS was lowest among the samples (p<0.05). The linoleic acid content of the control, the 10% SS, and the 20% SS was 28.68%, 41.04%, and 54.26%, respectively. The total unsaturated fatty acid content of the control, the 10% SS, and the 20% SS was 50.53%, 55.76%, and 64.93%, respectively. The linoleic acid and the total unsaturated fatty acid content were highest in the 20% SS (p<0.05). There was no significant difference in amino acid composition.
