Effect Of Different Algal Lees On Physicochemical Qualities Of Baked Potato Chips, Wen-Chieh Sung, Chang Jer Wu, Chorng Liang Pan, Yu Chin Lin
Journal of Marine Science and Technology
Lees of three different algae (a green alga Ulva fasciata, a brown alga Sargassum cristaefolium and a red alga Kappaphycus contonii), representing the leftovers from a seaweed polysaccharide extraction process using hot water and enzymes, were added separately to potato chip dough at a level of 2.5%. Antioxidant activity, water activity, color, firmness, overall acceptability and proximate composition of baked potato chips prepared from these dough and from dough without algal lees were evaluated. The rehydration capacity (49.87%) of red algal lees was significantly higher than that of the other lees. The firmness of baked potato chips with red algal …

Antioxidant And Immune-Stimulating Activities Of Hot-Water Extract From Seaweed Sargassum Hemiphyllum, Pai-An Hwang, Chwen-Herng Wu, Shu-Yun Gau, Shih-Yung Chien, Deng-Fwu Hwang
Journal of Marine Science and Technology
The hot-water extract of seaweed Sargassum hemiphyllum was evaluated antioxidant activity by using four different methods, including DPPH free radicals scavenging activity, Fe+2 chelating activity, superoxide anion radical scavenging activity and reducing power, and the immune-stimulating activity by using HB4C5 cells and J774.1 cells. It was found that the antioxidant activity was increasing in correlating with the concentration below 3.5 mg/ml. The HB4C5 cells showed the maximum relative activities of cell proliferation (174%) and IgM secretion (132%) at 120 µg/ml of hot-water extract. Overheating slightly reduced the immune-stimulating activity of hot-water extract. At 80 µg/ml, J774.1 cells showed the maximum …
