Abstract

This study was carried out to investigate the effects of addition of pork fat, olive oil and soybean oil on the quality and sensory of ground pork meat. The samples consisted of the ground pork meat containing 20% pork fat (GP-P), 20% olive oil (GP-O), and 20% soybean oil (GP-S). The chemical composition, surface color, fatty acid composition, water hold-ing capacity, pH, VBN content and TBARS value were determined for the ground pork meat as the quality characteristics, and the sensory score were also evaluated. The moisture, crude protein, crude fat and crude ash content were not different among the GP-P, GP-O and GP-S. The $L^{*}$(lighaess), $a^{*}$(redness) and $b^{*}$(yellowness) of /GP-P were higher than those of the GP-O and GP-S (p<0.05). Palmitic acid was the most abundant among saturated fatty acids, and palmitic acid content of GP-P (24.384%)was higher than that of the GP-O (15.611%) and GP-5 (14.423%). In case of unsaturated fatty acids, oleic acid of GP-P (43.773%) and GP-O (65.040%) were the highest, linoleic. acid for GP-5 (40.762) was the highest. The water holding capacity of GP-P was higher than that of the GP-0 and GP-5, the pH of GP-S was higher than that of the GP-P and GP-O, and the VBN content and TBARS value of GP-P was higher than that of the GP-O and GP-5 (p<0.05). The raw color of GP-0 and GP-S were higher than that of the GP-P (p<0.05), however the raw aroma was not different among the samples. In case of roasted ground pork meat, the aroma was not different among the samples, the taste, texture and palatability or GP-S were the highest among the samples, and the juiciness of GP-O and GP-S were higher than that of the GP-P(p<0.05).

본 연구는 돼지지방, 올리브유 및 대두유를 첨가한 분쇄돈육의 품질 및 기호성을 검토하기 위하여 돼지지방을 첨가한 분쇄돈육(GP-P), 올리브유를 첨가한 분쇄돈육(GP-O) 및 대두유를 첨가한 분쇄돈육(GP-S) 등 세 종류의 분쇄육을 제조하고 일반성분, 표면색깔, 지방산 조성, 보수력, pH, VBN 함량, TBARS값 및 순위법에 의한 기호성을 측정하였다. 수분, 조단백질, 조지방 및 조회분 함량은 GP-P, GP-O 및 GP-S 사이에 통계적 유의성이 없었다. $L^{*}$(명도), $a^{*}$(적색도) 및 $b^{*}$(황색도)값은 GP-P가 GP-O 및 GP-S보다 유의하게 높았다(p<0.05). 가장 많이 함유된 포화지방산은 palmitic acid로서 GP-P(24.384%)가 GP-O(15.611%) 및 GP-S(14.423%)보다 유의하게 높았다(p<0.05). 불포화지방산의 경우 GP-P(43.773%)및 GP-O(65.040%)는 oleic acid가 가장 많았으며, GP-S는 linoleic acid(40.762%)가 가장 많이 함유되어 있었다. 보수력은 GP-P가 GP-O 및 GP-S보다 높았으며, pH는 GP-S가 GP-P및 GP-O보다 높았고, VBN 함량 및 TBARS값은 GP-P가 GP-O및 GP-S보다 유의하게 높았다(p<0.05).가열하지 않은 분쇄돈육의 색깔은 GP-O 및 GP-S가 GP-P보다 우수하였으나(p<0.05), 향기는 시료들 사이에 통계적 유의성이 없었다. 가열 분쇄육의 경우, 향기는 시료들 사이에 유의한 차이가 없었으며, 맛, 조직감 및 전체적인 기호성은 GP-S가 가장 우수하였고(p<0.05), 다즙성은 GP-O 및 GP-S가 GP-P보다 우수하였다(p<0.05).
