This experiment analyzed the effect of temperature on subcritical water hydrolysis on natural poultry feathers for the isolation of high-value amino acids. Subcritical water hydrolysis is the process by which water in the range of 100 - 374 C converts and breaks down biomass. The hydrolysis machine was operated at three different temperatures (210, 230, and 250 C) at a constant flow rate of 10 mL / min. Differences between the hydrolysates were defined by performing Total Nitrogen, Chemical Oxygen Demand, and Nelson- Somogyi method testing. Initial hydrolysate analysis testing suggests that a low operating temperature and an operating time below 10 minutes may assist in getting optimum protein levels.
