Abstract

This study was carried out to establish the preparation condition of muskmelon jam. A central composite design was applied to investigate effects of muskmelon paste content(40, 45, 50, 55, 60 g), fructose ratio of sugar(20, 35, 50, 65, $80\%$) and pectin addition(l, 2, 3, 4, 5 g). The maximum sugar content was 61.48 $^{\circ}$Brix in 41.04 g of muskmelon paste content, $48.10\%$ of fructose ratio of sugar and 2.12 g of pectin content. The maximum value of softness was 2.71 g in 45.06 g of muskmelon paste content, $79.46\%$ of fructose ratio of sugar and 2.71 g of pectin addition. The minimum value of jelly strength was $0.04\;g{\cdot}cm$ in 47.80 g of muskmelon paste content, $63.0\%$ of fructose ratio of sugar and 1.99 g of pectin addition. The maximum value of organoleptic overall palatability was 5.89 in 55.65 g of muskmelon paste content, $73.19\%$ of fructose ratio of sugar and 2.42 g of pectin addition. The optimum conditions predicted for each corresponding physicochemical and organoleptic properties of muskmelon jam were 55.2 g(muskmelon paste content), $76.3\%$(fructose ratio of sugar) and 2.5 g(pectin addition).

참외를 이용한 적절한 가공식품 개발의 일환으로 참외잼을 제조하였으며, 참외잼에서 중요한 인자로 작용하는 참외 페이스트 함량(40, 45, 50, 55, 60 g), 첨가당에 대한 과당의 비율(20, 35, 50, 65, $80\%$) 및 펙틴함량(1.0, 2.0, 3.0, 4.0, 5.0 g)을 달리하면서 참외잼을 제조하였다. 당도가 가장 높게 나타난 참외잼 제조조건은 첨가된 과당함량의 비율이 $48.10\%$, 참외페이스트의 함량이 41.04 g 및 펙틴함량이 2.12 g일 때 61.48 $^{\circ}$Brix로 가장 높게 나타났다. Softness는 첨가된 과당의 함량이 $79.46\%$, 참외 페이스트가 45.06 g 및 펙틴함량이 2.71 g일 때 였으며, 젤리강도가 가장 낮게 나타난 조건은 첨가된 과당의 함량이 $63.0\%$, 참외 페이스트가 47.8 g 및 펙틴함량이 1.99 g일 때 $0.04\;g{\cdot}cm$로 나타났다. 관능검사 결과 전반적인 기호도에 대한 관능점수가 가장 높게 나타난 조건은 첨가당에 대한 과당의 비율이 $73.19\%$, 참외페이스트 함량이 55.65 g 및 펙틴함량이 2.42 g일 때였다. 참외를 가지고 잼을 제조하기 위해서는 참외 페이스트 55.2 g, 과당 $76.3\%$, 구연산 0.3 g, 펙틴 2.5 g을 첨가 혼합한 후 가열하여 제조할 때, 가장 우수한 품질의 참외잼이 제조됨을 알 수 있었다.
