The present invention relates to a grape jam composition composed of, based on 100 parts by weight of grape, 68-100 parts by weight of sugar, 12-36 parts by weight of low-sweet sugar, 5.5-12.0 parts by weight of low-calorie sweetener, 2.7-4.0 parts by weight of rare saccharide, 2.0-3.0 parts by weight of pectin, 0.3-0.7 parts by weight of gelatin, 0.01-0.48 parts by weight of acidifier, 0.05-0.06 parts by weight of vitamin C, and 0.02-0.1 parts by weight of grape flavor, and the purpose of the present invention is to provide delicious jam with good quality, capable of maintaining properties and functionalities, by adjusting the acidity to 0.5-1.2 and the pH value to 3.0-4.5. The method of the present invention comprises the steps of: removing grape vines, separating grape grains, removing grape peels and seeds, and then rapidly freezing, thereby freeze-storing the grape at 18°C or lower thawing the freeze-stored grape, transferring the grape into a raw material storage tank, and then removing foreign materials and selecting grapes weighting the raw material and a sub material, putting the materials into a vacuum type concentrator, mixing and concentrating the materials to make thick jam, and sterilizing the thick jam transferring the jam into a filler to fill a predetermined amount of jam in the filler, followed by sterilizing and cooling. The grape jam of the present invention has excellent quality and is good for health.COPYRIGHT KIPO 2015본 발명은 포도 100 중량부에 대하여, 설탕 68~100중량부, 저감미당 12~36 중량부, 저칼로리감미료 5.5~12.0 중량부, 희소당 2.7~4.0 중량부, 펙틴 2.0∼3.0 중량부, 젤라틴 0.3∼0.7 중량부, 산미제 0.01∼0.48 중량부, 비타민C 0.05∼0.06 중량부, 및 포도향 0.02∼0.1 중량부로 구성된 포도잼 조성물이며, 산도 0.5~1.2, pH 3.0~4.5로 맞추어 잼의 물성과 관능을 유지시킬 수 있는 좋은 품질의 맛있는 잼을 제공하는데 있다.포도 줄기를 제거하고 알맹이를 분리하여 과피와 씨를 제거한 후 급속 동결하여 18℃이하로 냉동 보관하는 단계와, 전기의 냉동 보관된 포도를 해동하여 원료저장조로 이송하여 이물질을 제거 및 선별하는 단계와, 원부재료를 계량하여 진공농축기에 넣고 혼합하여 농축한 후 걸쭉하게 잼이 잘 만들어지면 살균하는 단계와, 충진기로 이송하여 일정량을 충진하고 살균한 후 냉각하는 단계로 구성된다. 본 발명의 포도잼은 품질이 우수하고 건강에 좋다.
