The present invention relates to a low molecular weight polysaccharide kelp extract ensuring antioxidative functions, a kelp/tuna-derived liquid sauce containing the same, and a production method thereof. More specifically, the present invention relates to a low molecular weight polysaccharide kelp extract having antioxidative functions, which is produced by the following steps: obtaining an extract containing low molecular weight storage polysaccharide while preventing elution of high molecular weight mucous polysaccharide as much as possible with high temperature heating in purified water with regulated pH4-5 and undergoing ultra filtration. The present invention further relates to a kelp/tuna liquid sauce ensuring antioxidative functions and purposes, which is produced by the following steps: extracting smoked tuna at a high temperature to process protein substances in an aqueous solution into low molecular substance by enzymatic degradation mixing the tuna extract having functionality and flavor adding seasoning ingredients such as soy sauce, salt, sugar, and amino acid and mixing, dissolving, and sterilizing the same.COPYRIGHT KIPO 2017본 발명은 항산화능을 가진 저분자다당류 다시마추출물과 이를 함유한 다시마 참치액상 소스 및 그의 제조방법에 관한 것으로, 먼저 pH4~5로 조정한 정제수에 고온가열로 고분자 점질다당류의 용출을 최대한 억제시키면서 저분자 저장다당류 등을 포함한 추출물을 얻고 한외여과에 의하여 항산화능을 가진 저분자다당류 다시마추출물과 훈연참치를 고온에서 추출하여 수용액 중에 있는 단백물질을 효소분해에 의하여 저분자화 하여 기능성을 가진 맛을 가진 참치 추출을 혼합한 후, 간장, 소금, 설탕, 아미노산 등의 조미원료를 넣고 혼합 용해, 살균하여 다용도의 항산화능을 가진 다시마참치액상 소스에 관한 것이다.
