Abstract

This study was carried out to investigate the possibility for utilization of waste materials and the characteristics of pork by feeding citrus byproducts. The groups consisted of the pork without citrus byproduct (TB-0) and the pork fed with 6% and 10% citrus byproduct during growing and fattening period (TB-1). The contents of moisture, crude protein, crude fat, crude ash, vitamin $B_1$ and $B_2$, total amino acids, and caloric were not significantly different between TB-0 and TB-1 (p>0.05). The contents of cholesterol and the magnesium of TB-1 were lower than those of TB-0. Palmitic acid was the most abundant among saturated fatty acids while oleic acid was the most abundant among unsaturated fatty acids in both groups. In case of sensory score, the color and aroma of raw meat and taste, texture, juiciness and palatability of boiled meat were not influenced by feeding of citrus byproduct. But the flavor preference of boiled meat of TB-1 was higher than that of TB-0.

본 연구는 제주도에서 폐기되고 있는 밀감 부산물을 돼지에게 급여하여 페기물의 이용과 기능성 돈육의 생산을 위하여 실시하였다. 돼지는 밀감 부산물을 급여하지 않은 등심육(TB-0) 및 육성기에 6% 급여한 후 비육기에 10% 급여한 등심육(TB-1)을 대상으로 여러 가지 영양성분 분석과 관능검사를 실시한 결과 수분, 조단백질, 조지방, 조회분 및 열량은 시료들 사이에 차이가 없었다. 콜레스테롤 함량은 TB-1(41.5 mg/100g)이 TB-0)48.9 mg/100 g)보다 유의하게 낮았다. 무기질 중에서 Mg은 TB-0(192 ppm)가 TB-1(161 ppm)보다 유의하게 높았으며, 비타민 $B_1$ 및 $B_2$는 시료들 사이에서 차이가 없었다. 총아미노산 함량은 TB-0 및 TB-1이 각각 19.51 및 18.65%이고, 총유리아미노산 함량은 각각 469.44 및 479.45 mg/100 g으로 처리구간에 유의한 차이가 없었다. 포화지방산은 palmitic acid가 가장 많았고, 불포화지방산은 oleic acid가 가장 많았다. 생육과 가열육의 맛, 조직감, 다즙성 및 전체적인 기호성은 밀감 부산물 급여에 의한 영향은 없었으며, 풍미는 TB-1이 TB-0보다 유의하게 높았다.
