| Sumario: | Pineapple juice (Ananascomosus L. cv. Pattavia) has high amounts of sugar, making it potential to be produced into Nata.The study will enable efficient utilization of pineapple juice and will also provide a new product dimension to the pineapple farmers who are not getting the right price for their product. The objectives of this research were to study the various contents of (NH4)2SO4on total soluble solids, pH, % ethanol, thickness and yield of Nata de pina from pineapple juice (Ananascomosus L. cv. Pattavia) fermented by Acetobacter xylinum. (NH4)2SO4 was used as a nitrogen source and its contents for Nata de pina production at 30oC for 15 days were 0.3, 0.4 and 0.5 % w/v. Increasing 0.3 - 0.5 %w/v (NH4)2SO4 contents improved to utilize total soluble solids and % ethanol of Nata de pina and the lowest pH of Nata de pinawas obtained from using 0.5 % w/v of (NH4)2SO4. Using 0.5 %w/v of (NH4)2SO4led to the highest values of thickness and yield of Nata de pina after 15 days which were 12.14 mm and 100.02 g, respectively. |
