Fish scale-derived hydroxyapatite for alveolar ridge preservation.

Alveolar ridge resorption following tooth extraction poses significant challenges for future dental restorations. This study investigated the efficacy of fish scale-derived hydroxyapatite (FSHA) as a socket preservation graft material to maintain alveolar bone volume and architecture. FSHA was extracted from *Labeo rohita* fish scales and characterized using Fourier transform infrared (FTIR) analysis.

Heat penetration attributes of milkfish () thermal processed in flexible pouches: a comparative study between steam application and water immersion.

The difference in the heating penetration characteristics of product processed in retort by steam-air application and water immersion was studied. Fresh milkfish () packed in dry pack and in oil medium, both in flexible pouches, was thermal processed to minimum value of 7.77 at 121.

Studies on chemical composition of yellowfin tuna (, Bonnaterre, 1788) eye.

Chemical composition ., fatty acids, amino acids and minerals of yellowfin tuna ( eye were analyzed for better utilization of fish processing discards. Analysis of fatty acids composition by gas chromatography-mass spectrometry revealed the presence of polyunsaturated fatty acids namely docosahexaenoic acid, eicosapentaenoic acid, arachidonic acid and linoleic acid at the levels of 37.

Nutritional evaluation of processing discards from tiger tooth croaker, .

Processing discards from tiger tooth croaker, such as head, viscera, and swim bladder, were analyzed for proximate, biochemical, fatty acid, and mineral composition. The proximate analysis showed high protein content (21.04%) in the swim bladder and high fat content (4.

Characterisation of hydrolysates prepared from engraved catfish (Nemapteryx caelata) roe by serial hydrolysis.

Protein hydrolysates were prepared from defatted engraved catfish roe using alcalase enzyme by a two-stage serial hydrolysis process. The soluble hydrolysate formed after first stage of hydrolysis was removed (RH-1) and fresh enzyme was added at the same concentration to achieve further hydrolysis (RH-2). Further, compositional, surface-active and antioxidant properties of both hydrolysates were compared.
