Abstract

Number of vegetarians in Indonesia is rising. This increase may be attributed to improvement of people^s knowledge regarding health benefits of a high fiber plant-based diet in relation to reducing the risks of degenerative diseases. However, high fiber food products, especially mushroom-based food products that are accepted by panelists, are limited to oyster and straw mushrooms. The goal of this research is to get best formula based on organoleptic and crude fiber content from Auricularia polytricha and red dragon fruit peel extract as a food for vegetarian diet.This study used experimental study which was arranged in factorial manner with two experimental factors: concentration and volume of red dragon fruit peel extract (25 ml and 50ml) and proportions of wheat flour and Auricularia polytricha (30:70,50:50,70:30). A significant (p<0.05) effect on color, taste, and texture were observed with nugget ingredient formulation, and there was no significant effect on aroma (p>0.05). The best formula for Auricularia polytricha nuggets with addition of red dragon fruit peel extract is J3E2 with a composition of 70% Auricularia polytricha and 30% wheat flour with addition of 50 ml red dragon fruit peel extract, which has the highest crude fiber content (36,88%) with anthocyanin content of 0,99%.
