ETLINGERA ELATIOR AS A NATURAL DEODORIZER TOWARDS THE STEEPING OF ULVA LACTUCA SEAWEED

Abstract

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 (p0,05) 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%.
