  • Description: There are several challenges to utilizing U. lactuca as a seaweed steeping powder, such as an unpleasant odour caused by off-odor volatile compounds, i.e. the group of fatty acid derivatives, several aldehyde compounds, and some compounds containing sulphur. This research aimed to produce steeping of U. lactuca seaweed immersed in a natural deodorizer, Torch Ginger (E. elatior) extract, with different treatments to eliminate the off-odor scent. The research consisted of one factor, which was immersion using E. elatior extract with a concentration 0% (sample A), 10% (sample B), 20% (sample C), 30% (sample D), and 40% (sample E). The data was analyzed using SPSS v.21 of ANOVA. If there was any significant effect, the data were further analyzed using Duncan Multiple Range Test with significance level 5%. According to the research, the result showed that the immersion treatment in E. elatior extract had a significant effect (p<0,05) on the observed variables i.e. moisture, crude fiber, dietary fiber in the steeping, impurities, total of polyphenol, RSA DPPH, and sensory test on the steeping (color, flavour, taste, turbidity, appearance, and total), but not significantly affected (p>0,05) on the water extract observation variable. A concentration of 40% of E. elatior (Sample E) was concluded as the best treatment with characteristics as follows: moisture 3,89 ± 0,05%, crude fiber content 6,73 ± 0,03%, water-soluble dietary fibre 2,18 ± 0,01%, water-insoluble dietary fiber 24,58 ± 0,04%, crude impurities 3,48 ± 0,07, in-water extract 65,90 ± 44,43%, a total of phenolic 391,35%, and antioxidant activity 20,61%.
