Generally, the flour used is derived from wheat. However, the flour can also be made from rambutan seed that have nutritional value which is good for health. The objectives of this study were to: 1) find the best formula from rambutan seed flour biscotti; 2) know the nutritional value of the selected formula; and 3) know the consumer acceptability. This research was experiment with one factor model in different propotional levels (40; 60; 80; 100), and it analyzed using chemical test and descriptive analysis of sensory quality. The nutritional value of biscotti obtained were compared with nutritional value of rambutan seed flour. These include energy, protein, carbohidrates, fat, ash, Vit C, fiber, and antioksidant. The result showed that 1) the best formula on sensory quality of rambutan seed flour biscotti is resulting from more than a half rambutan seed flour subtitutions; 2) the selected formula contain energy, protein, carbohidrates, fat, ash, Vit C, fiber, and antioxidant; and 3) the consumer acceptability of biscottti from the best formula namely: odor, texture, crunchiness, taste and overall acceptability.
