Chara corallina is an algae with relatively high chlorophyll content compared to other freshwater algae. Therefore, it is interesting to use it in food products. Then, the objective of this study was to develop noodle product from Chara corallina. The study was performed on basic recipe of noodles, suitable factors for noodle production and quality of noodle product from Chara corallina. After the experiment, the results showed that the proper basic formula consisted of 200 grams of all-purpose wheat flour, 50 grams of chicken eggs, 25 grams of water and 15 grams of limewater. The optimum ratio of algae to water, amount of gua gum and amount of sodium bicarbonate used for noodle production were 1:0 (w /w), 0.2 grams /100 grams of flour and 0.05 grams/100 grams of flour, respectively. After the noodle products from Chara corallina was dried at 90 °C for 1 hour and 30 minutes, the quality of noodle product was analyzed. The result showed that dried noodle product had water activity (aw) of 0.48, brightness value (L *) was 65.24, green color values (-a *) was -0.03 and the yellow color value (b *) was 31.07. The content of moisture, ash, protein, fat, fiber and carbohydrates were 6.27%, 1.03%, 13.79%, 1.46%, 0.16% and 77.46% respectively, while the energy value of noodle was 378.11 kcal. When texture analysis was performed with Texture analyzer the result showed that tensile strength, springiness, hardness, adhesiveness, firmness and work of shear were 25.82 grams, 19.31 mm., 4,035.65 g, 37.31 g.Sec., 362.12 grams and 2,208.14 grams.Sec. respectively. For microbiological property, total variable count was 6.15 × 102 colonies per gram, yeast and mold content was less than 10 colonies per gram, MPN Escherichia coli per gram was less than 3.0 and Salmonella spp. was not found. Therefore, the noodle product from Chara corallina is an alternative way to produce products that add value to local algae and continue to generate income from raw materials in the community.
