Abstract

This study was carried out to investigate the effect of the addition of lotus (Nelumbo nucifera) root and leaf powder on the quality characteristics of pork patties. The pork patties were of four types: nothing added (CTL), 0.5% lotus root powder added (LRP), 0.25% lotus root and 0.25% lotus leaf powder added (LRLP), and 0.5% lotus leaf powder added (LLP). There was no significant difference in $L^*$ value (whiteness), cohesiveness, gumminess, chewiness, water holding capacity, VBN content, and total bacterial amount. The moisture was highest in CTL, protein was highest in LRLP, fat was highest in LRLP and LLP, and ash was highest in LRLP (p<0.05). The total polyphenol content of the CTL, LRP, LRLP, and LLP were 3.34, 3.64, 3.90 and 3.90 mg/100 g, respectively. The $a^*$ value was highest in CTL, and the $b^*$ value of LRLP and LLP were higher than those of CTL and LRP (p<0.05). The hardness of CTL and LRP were higher than those of LRLP and LLP, and springiness was lowest in LLP (p<0.05). The cooking loss, thickness change, diameter changes, and pH were highest in CTL (p<0.05). The TBARS was highest in CTL, and was lowest in LLP (p<0.05).

본 연구는 연근 및 연잎분말의 첨가가 돈육 patty의 품질 특성에 미치는 영향을 검토하였다. 돈육 patty는 돈육 88%, 대두유 5%, 냉수 5%, 소금 2%를 배합하여 제조한 대조군(CTL), 여기에 연근분말 0.5% 첨가한 것(LRP), 연근분말 0.25% 및 연잎분말 0.25% 첨가한 것(LRLP), 그리고 연근분말 0.5% 첨가한 것(LLP) 등 네 종류의 돈육 patty를 제조하였다. 그리고 일반성분, 총 폴리페놀화합물 함량, 색깔, 기계적 조직감, 보수력, 가열감량, 두께 및 직경 변화, pH, VBN 함량, TBARS 및 총균수를 측정하였다. 수분함량은 CTL, 단백질 함량은 LRLP, 지방함량은 LRLP 및 LLP, 그리고 회분함량은 LRLP가 가장 높았다(p<0.05). CTL, LRP, LRLP 및 LLP의 총 폴리페놀 함량은 각각 3.34, 3.64, 3.90 및 3.90 mg/100 g이었다. 명도($L^*$)는 시료들 사이에 유의한 차이가 없었으며, 적색도($a^*$)는 CTL이 가장 높았고, 황색도는 LRLP 및 LLP가 CTL 및 LRP보다 높았다(p<0.05). 경도는 CTL 및 LRP가 LRLP 및 LLP보다 높았으며, 탄성은 LLP가 가장 낮았고, 응집성, 검성 및 저작성은 시료들 사이에 유의한 차이가 없었다. 보수력은 시료들 사이에 유의한 차이가 없었으나, 가열감량, 두께 및 직경 변화는 CTL이 가장 높았다. pH는 CTL이 가장 높았다(p<0.05). VBN 함량과 총균수는 시료들 사이에 유의한 차이가 없었다. 그리고 TBARS는 CTL이 가장 높고, LLP가 가장 낮았다(p<0.05).
