3. Result and Discussion: 3.1 Compatibility Study of Keratin/Alginate Blends: The XRD spectra of blends were compared to the control spectra of native keratin and alginate as mentioned in Figure 1. In XRD spectra, the native keratin and native alginate give a highest intensity at near 7543 and 4100 at about 19° and 14° angle of 2θ respectively, which is also confirmed by other researchers [16–18]. The spectra of keratin/alginate blends prepared at a ratio of 10:90, 30:70 and 50:50 gives a highest intensity peak 3573, 5128 and 3264 at 22°, 6.8° and 7.1° angle of 2θ respectively. The XRD spectra of all blend ratios gives a new peak in between 6°-8° angle of 2θ which is not present in the spectra of native keratin and alginate, this depict that the structure of native keratin and alginate become altered and form a new structural pattern in blend form. The XRD spectra of blend scaffold revealed that the intensity of blend has transformed as compared to the control XRD spectra which confirm that the compatibility exists in between keratin and alginate. Several works are reported for the biomaterial preparation from various blends such as chitosan/agar, agar/soy-protein, carboxy-methyl-cellulose/soy protein, soy protein/agar etc. [18], but in the author’s best knowledge none of the report available which can explain the compatibility in between keratin and alginate. 3.2 Optimization of Process Parameter for scaffold preparation: The results obtained by the run of 20 experimental
