Abstract

This study investigated methods to improve the quality of Topokkidduk using grapefruit seed extracts and acid regulation agents. Topokkidduk was investigated in terms of its moisture, color, pH, texture, microbial composition, and sensory properties. The moisture content of Topokkidduk was highest for Topokkidduk supplemented with grapefruit seed extracts. The color of Topokkidduk (the L value) decreased, whereas the "a" value increased with the addition of grapefruit seed extracts. The texture of Topokkidduk was affected more by additives than storage temperature. The addition of grapefruit seed extracts and acid regulation agents were effective for the inhibition of microbial activity in Topokkidduk during storage. The overall acceptability values of Topokkidduk (without supplements) were highest among the samples. These results suggest that grapefruit seed extracts and acid regulation agents can be used to control microbial load and moisture levels in Topokkidduk.

국내 쌀가공산업의 활성화로 인해 떡류 시장은 활발해지고 있으나 떡의 노화현상으로 인한 유통상의 제한점으로 시장개척에 어려움이 따르고 있다. 따라서 떡류 제품 중 대중에게 인지도가 가장 높은 가래떡의 일종인 떡볶이떡에 자몽씨 추출물과 산도조절제를 첨가하여 제조된 떡볶이떡의 품질개선을 확인해보고자 하여 이들의 품질평가를 수분, 색도, pH, 기계적 조직감, 미생물 특성 및 관능적 특성을 통해 살펴 보았다. 떡볶이떡의 수분함량은 저장기간 동안 자몽씨 추출물 첨가군에서 가장 높게 나타났으며(p<0.05), 떡볶이 떡의 색도측정 결과 산도조절제 첨가떡의 L, a, b 값이 자몽씨 추출처리군과 대조군보다 낮게 나타났다(p<0.05). 떡볶이떡의 기계적 강도는 저장 온도보다 첨가제에 더 큰 영향을 받는 것으로 나타났다. 즉 자몽씨 추출물과 산도조절제를 첨가한 떡볶이의 경도가 무첨가군인 대조군보다 낮게 나타났다. 자몽씨 추출물과 산도조절제의 첨가는 떡볶이떡의 미생물 생장을 효과적으로 지연시켜 주는 것으로 나타났고 전반적인 기호도는 첨가제를 넣지 않은 대조군에서 가장 높은 점수를 획득하였다. 본 연구결과를 통해 자몽씨 추출물과 산도조절제의 첨가가 저장중 미생물 생장을 지연시키며 저장 15일까지 품질을 유지시켜 주어 관능적 평가가 가능한 것으로 나타나 첨가제로써 자몽씨 추출물과 산도조절제가 떡볶이떡의 품질특성에 긍정적인 영향을 주는 것으로 확인되었다.
