Languages of publication
The purpose of this research is to utilize Gracilaria sp. Seaweed in making nori and knowing the effect of the drying process on the level of preference of panelists on nori products. This research was conducted at the Fisheries Technology Laboratory of the Faculty of Fisheries and Marine Sciences and Food Chemistry Laboratory Processing, Food Processing Technology Department, Faculty of Agricultural Technology, Bogor Agricultural University in January 2019. The research method used was the experimental method, with 20 semi-trained panelists and three treatments using oven drying, direct sunlight, and sunlight with modification of plastic housing. The test observed in the research is the hedonic test with characteristic organoleptic parameters including appearance, aroma, texture, taste and nori state. In addition, physical and chemical tests were carried out on the best treatment. Chemical tests covered both protein content and water content. Physical tests are hardness and thickness tests. The results of the research show that all the drying treatments on the nori are still favored by the panelists, but the drying treatment using an oven is preferred by the panelists as evidenced by the average value of the appearance characteristics of 6.40; aroma 6.30; 5.90 texture and taste 6.50. The chemical characteristics were as follows: water content 16.85%, the protein content 11.88%, fiber content 5.8%, and the physical characteristics related to hardness of 150 gf, with nori thickness of 0.25 mm.
