“…The lipid region, amide I and III region and proline-hydroxyproline (Pro-Hyp) region are the main regions for conformational changes of collagen structure [ 38 ]; the 1443 and 891 cm −1 regions are two Raman bands in the vibrational region of carbonate ions [ 39 ], and these bands were completely present in the profiles of RBC and the type I collagen standard. In the Raman spectrum of HAP, the occurrence positions of a strong peak, moderate intensity peaks and lower intensity peaks are similar to the structural distribution of synthetic and natural HAP previously studied [ 40 , 41 ]. The Raman spectrum waveform of MRB basically corresponded to the characteristic peaks of HAP and RBC.…”

As a natural calcium resource, animal bone needs to be miniaturized to the nanoscale to improve palatability and absorption capacity. To explore the mechanism of high-pressure homogenization (HPH) in preparing natural bone aqueous nanosuspensions, the relationships between the changes in protein conformation, solubility and quality characteristics of rabbit bone aqueous suspensions (RBAS) prepared by different HPH cycles were studied. The results showed that the improvements in particle size, stability and calcium solubility of RBASs could be mainly attributed to the improvement of protein solubility induced by the changes in protein conformation. HPH treatment led to the denaturation and degradation of protein in rabbit bone, generating soluble peptides and improving the stability of the suspensions by enhancing the surface charge of the particles. When collagen as the main protein was partially degraded, the hydroxyapatite in the bone was crushed into tiny particles. The increase in the particle-specific surface area led to the release of calcium ions, which chelated with the peptides to produce peptide calcium. However, excessive HPH treatment caused the production of protein macromolecular aggregates and affected the quality of RBASs. This study is helpful to promote the application of HPH technology in animal bone nanoprocessing.

“…The obvious phosphate group peaks in NBPs were observed by Raman and IR spectra, and the characteristic peaks representing phosphate in the Raman spectrum were more elaborate. The Raman spectra were dominated by a very strong peak at 963 cm/ cm (v1), the medium intensity peaks presented at 432 cm −1 (v2), 586 cm −1 (v4), and 1,073 cm −1 (v3), and the lower intensity peaks appeared at 442 cm −1 (v2), 609 cm −1 (v4), and 1,042 cm −1 (v3), whose distributions were similar to the structures of synthetic and natural hydroxyapatite (Heidari et al, 2018;Nam et al, 2019).…”

“…Generally, bone use has been limited in the field of food study due to its coarse and grainy texture, and bone is still mainly used as animal feed or plant fertilizer because of its low price (Buckley et al., 2012; Genisel et al, 2012). To improve the added value of animal bones, some of them are used for intensive processing, including extraction of bone protein (Dong et al., 2014; Song et al., 2016) and bone oil (Choi et al., 2016; Hagura et al., 2002), and preparation of natural hydroxyapatite (Heidari et al., 2018; Nam et al., 2019), gelatin (Li et al., 2013; Wang et al., 2016), and essence (You et al., 2020). However, the utilization of bone in these processes is limited, and more comprehensive use of bone still needs further study.…”

The chemical composition and hardness of bovine bone, porcine bone, chicken bone, and rabbit bone were compared, as well as the influence of nanoprocessing on the physicochemical characteristics of these bone powders. A series of nanofabrication processes led to an increase in bone minerals and the loss of protein and fat. The hardness of softened bovine bone was still the largest, whereas chicken and rabbit bones were relatively soft. There were no significant differences in the functional groups between nanoscale bone powders. Overall, nanomachining significantly reduced and homogenized the bone particle size and improved the color and release rate of calcium ions of bone powders at the same time; these effects were different for several bones. Nanoscale rabbit bone had higher comminution efficiency, as well as satisfactory nutritional value, color, and product yield, which supports its strong development potential.

Current biomedical field demands intensive research on cost-effective and high availability materials to fulfil its various applications. Owing to its similar characteristic to human bone, biological hydroxyapatite (HAp) has been used as an alternative in bone replacement and implantation. In this study, biological HAp was extracted from bovine bones via calcination. Powders calcined at 700 °C and 900 °C showed the presence of HAp. The FESEM analysis shows that the irregular morphology emerged and the size was increasing as the calcination temperature increased. By increasing the temperature of 1100 °C, β-TCP started to develop and influenced the ratio of Ca/P. At 900 °C, the Ca/P ratio obtained was 1.70, and closest to the theoretical ratio of Ca/P. The presences of trace elements like Ca, Mg, Sr Na, K and Zn in all samples are proved via EDS analysis, and these elements help to enhance the bioactivity hence make it a good alternative in biomedical applications.
