“…As shown in Figure A, the CD spectrum of GE only showed a negative peak at 198 nm corresponding to the random coil conformation. In fact, it has been reported that because GE is obtained by changing the triple-helix structure of collagen, the positive peak at 223 nm of GE disappears . The α-helix of the protein resulted in a positive peak at 192 nm and negative peaks at 208 and 222 nm .…”

The purpose of this work was to develop a facile strategy based on self-crosslinking between the core and wall materials in the coacervation system for effective procyanidins (PCs) encapsulation. The coacervates were constructed through the interaction of bioactive PCs, gelatin, and sodium alginate, followed by forming cationic bridge of sodium alginate-calcium ions to improve the stability of PCs. When the concentration of PCs and calcium ions were 6.25 and 0.24 mg/mL, respectively, the PCloaded coacervates showed spherical shape with a size about 150 nm, and the microcapsulation efficiency and yield was 81.19 ± 1.47 and 87.86 ± 2.67%, respectively. The photothermal stability of PCs was effectively improved by embedding them in coacervates. The decrease of mitochondrial membrane potential in PC-12 cells induced by H 2 O 2 was significantly inhibited by PC coacervates, demonstrating an improved protection effect of PCs after being encapsulated in coacervates.

“…The lower yields, compared with the 72% yield of a-N-CDs, clearly indicate that a high fraction of the biomass is not convertible into CDs. In fact, fish scales also contain a large fraction of minerals such as CaCO 3 (27–47% [ 36 , 37 , 38 ]). An average composition of the scales was obtained by elemental analysis as reported in Table 1 .…”

Biobased Carbon Dots: From Fish Scales to Photocatalysis

et al. 2021

The synthesis, characterization and photoreduction ability of a new class of carbon dots made from fish scales is here described. Fish scales are a waste material that contains mainly chitin, one of the most abundant natural biopolymers, and collagen. These components make the scales rich, not only in carbon, hydrogen and oxygen, but also in nitrogen. These self-nitrogen-doped carbonaceous nanostructured photocatalyst were synthesized from fish scales by a hydrothermal method in the absence of any other reagents. The morphology, structure and optical properties of these materials were investigated. Their photocatalytic activity was compared with the one of conventional nitrogen-doped carbon dots made from citric acid and diethylenetriamine in the photoreduction reaction of methyl viologen.

“…Alcalase hydrolysis of fish protein from seabass (Dicentrarchus labrax) by-products gave a hydrolysate that was added to whiting (Merlangius merlangus) mince ex texture softening effect [695]. In a different study, Alcalase was employed in the pretreatment of the scales of a different species of seabass (Lates calcarifer) and grey mullet (Mugil cephalus) for the production with yields of gelatin 14.1-15.2% that presented high protein content (88.6-90.0%) with ash (1.43-1.55%) and no fat [696]. The gelatin was identified as type A due to its pH value.…”
