Abstract

This study was carried out to evaluate the nutritional properties of spreadable liver product. The composition of fresh hog liver used as raw material was 70.5% moisture, 5.2% fat, 20.3% protein and 1.2% ash. The composition of the spreadable liver product was 55.3% moisture, 19.4% protein, 21.6% fat and 3.7% ash. The total amino acid content of fresh liver was 18.69 g/100 g with glutamic acid at the highest level of 2.57 g/100 g. The total amino acid content of liver product was 18.03 g/100 g with glutamic acid at 2.28 g/100 g. The essential amino acid content was found to be 42% of total amino acids. The fatty acid analysis of fresh liver revealed oleic acid to be present at the highest level of 28% in the unsaturated fatty acid portion, and palmitic acid to be highest at 20.7% in the saturated fatty acid portion. The oleic acid content of the liver product was 40%, and the palmitic acid content was 20.4%. The level of cholesterol in fresh liver was 178.0 mg/100 g compared to 118.0 mg/100 g in the liver product. Regarding mineral analysis, the K and P contents of fresh liver were 362.2 mg/100 g and 339.1 mg/100 g, respectively, and 336.1 mg/100 g and 213.3 mg/100 g in the liver product, respectively. Many other minerals including Na, Mg, Ca and Fe were present in the product. Based on these results, the spreadable liver product made with hog liver was found to be a quality food with nutritional benefits and that is easy to consume.

본 연구는 돼지 간을 이용한 spreadable liver product의 영양학적 특성을 조사하였다. 원료용 간의 수분함량은 70.5%, 단백질 20.3%, 지방 5.2%, 회분 1.2%의 결과를 보였다. 또한 제품의 수분함량은 55.3%, 단백질 19.4%, 조지방 21.6%, 조회분 3.7%로 나타났다. 아미노산 함량은 원료용 간이 18.69 g/100 g이었으며 그 중 glutamic acid가 2.57 g/100 g으로 가장 높게 나타났다 제품에도 아미노산 총 함량은 18.03 g/100 g으로 나타났으며, glutamic acid가 2.28 g/100 g으로 가장 높게 나타났다. 제품의 필수아미노산은 전체 아미노산 함량 중 42%를 차지하였다. 원료용 간에서 지방산 조성은 불포화지방산 중 oleic acid가 28.0%로 가장 높게 나타났으며, 포화지방산인 palmitic acid가 20.7%로 나타났다. 제품에서는 oleic acid의 함량이 40.0%, palmitic acid가 20.4%로 나타났다. 원료용 간 및 제품의 콜레스테롤 함량은 178.1 mg/100 g 및 11.8 mg/100 g로 나타났다. 무기질 함량은 원료용 간이 K가 362.2 mg/100 g이었으며 P의 함량은 339.1 mg/100 g로 높은 함량을 나타내었다. 제품의 무기질 함량은 원료용 간에 비해 Na가 894.5 mg/100 g로 높은 함량을 보였으며 P의 함량은 336.1 mg/100 g이며, K는 213.3 mg/100 g를 포함하였다. 그 외에도 Mg, Ca 및 Fe 등 다양한 무기질도 함유하고 있었다. 돼지 간을 이용한 spreadable liver product는 영양학적으로 매우 우수하며 가공제품으로 쉽게 이용될 수 있을 것이다.
