  Background and Objective: Broiler feather waste (BFW) resulting from poultry slaughter houses (PSHs) is considered a serious solid waste problem. To deal with this problem, the waste can be hydrolyzed to create broiler feather protein concentrate (BFPC), which has the potential to serve as feed material for non-ruminant animals. This study aimed to evaluate the in vitro protein digestibility (In-VtPD), yield and chemical composition (CC) of Broiler feather protein concentrate (BFPC) prepared under different conditions. Methodology: This study involved four types of processes and used a combination of chemical and physical processes. The chemical processes used 1 M HCl (10 and 20% (v/v) and 1 M NaOH [10 and 20% (w/v)], while the physical processes used a high pressure heating system. The treatment consisted of four conditions including P0 (control /without hydrolysis), P1 [(20% (w/v) 1 M NaOH+autoclaving (21 Psi)], P2 [(20% (v/v) 1 M HCl+autoclaving (21 Psi)] and P3 [10% (v/v) 1 M NaOH+10% (w/v) 1 M HCl+autoclaving (21 Psi)]. A completely randomized design (CRD) with 5 replications was used and the data obtained were evaluated using analysis of variance (ANOVA). Results: The results showed that different hydrolysis conditions had significant effects (p<0.01) on the In-VtPD, yield, Cc and pH of BFPC but had no significant effect (p>0.05) on the protein content. The hydrolysis process using 20% (w/v) 1 M NaOH+autoclaving (21 Psi) (P1) significantly increased the In-VtPD of BFPC (59.53±0.7%). The combination of chemical and physical processes was able to hydrolyze the components of keratin protein in feather waste. The resulting yield was not different from that of the other treatments (P2 and P3). The hydrolysis process uses a chemical and physical combination to maintain a stable protein composition but the digestibility level of the protein increases. The amino acid profiles of BFPC before and after the hydrolysis process did not differ significantly. The amino acid component in BFPC is dominated by glutamic acid. In the composition of the constituent substances BFPC is dominated by K2O and CaO compounds. Conclusion: The hydrolysis process that uses a combination of chemical [20% (w/v) 1 M NaOH] and physical processes (autoclaving) (P1) is the best hydrolysis treatment. Therefore, this treatment is recommended as the best process to produce feather flour concentrate.

  Collagen is a hydrocolloid products of animal protein resulted in partial hydrolysis. Cow bones abattoir by-product is a product that is rich in collagen proteins, thereby it’s potentially as a source of raw materials. The protein collagen is now widely used as a dietary supplement. This study aimed to evaluate the chemical properties of the extract collagen product from os scapula of Bali cattle through the application of some types of extractant in the production process. Laboratory experimental method was used in this study. A total of four types of extractant was applied, namely: (1) distilled water, (2) ethanol 60% (v/v), (3) CH3COOH 0.5 M and (4) Ca(OH)2 0.5 M. The pattern of Complete Randomized Design (RAL) of Undirectional pattern and the analysis of variance was used as the study design and data analysis, while Duncan's Multiple Range Test (DMRT) was used as a further test if it was significant. The results showed that the use of different extractant extracts on the collagen production processes using raw materials from os scapula of Bali cattle affected (p<0.05) the value of the yield, moisture content, protein content and calcium levels, but there was no significant effect (p>0.05) on lipid levels and phosphorus levels. Extract collagen from os scapula of Bali cattle produced using four types of extractants have functional properties identical functional groups based on the presence of CO, C-O, OH, CH and N-H bond.
