Gliederung

Text

Postharvest processing is one of the crucial aspects in utilizing Sargassum sp. as the raw material of tea product as the fishy flavor and nutrition loss caused by pre-treatment and drying process. We evaluated the deodorization technique and drying method consecutively in this present study by investigating the effect of deodorization and different drying method on the final quality of the dried algal samples. Sargassum duplicatum harvested from Talango Island, Sumenep was used in this study, algal samples were immersed in a charcoal of Tectona grandis suspension in water at the concentration of 5, 10, 15% w/v for 6,12,18h, and then dried by using three different drying methods such as oven drying, sun drying and air drying. This study resulted that the deodorization could reduce the amount of phenols, flavones, fishy and other flavours where the immersion in a suspension of 15% w/v for 18h was the best method in deodorizing the algal samples, but retaining the lowest phenols and flavones. Furthermore, different drying methods generated finally dried algal sample characteristics such as amount of phenols, flavones, antioxidant activity and profile of volatile compounds. Air drying was the best method in this study, followed by sun drying and oven drying. Overall, the deodorization by using charcoal of Tectona grandis, followed by air drying could be a set of traditional approach for brown seaweed postharvest processing for tea raw material.
