Abstract This study investigates the sustainable extraction of nano-Hydroxyapatite (nano-HAp) from Lates calcarifer fish bones, a by-product seafood industry, through thermal calcination. Nano-HAp was synthesized at two temperatures (650°C and 700°C), resulting in rod-like (42 nm) spherical (98 particles, respectively. Both samples were identified as B-carbonated HAp, with Ca/P molar ratios 1.842 for HAp 650-4h 1.856 700-4h, confirming presence B-type which has higher than standard found...
On 5 November 2020, a poisoning event involving four people by the consumption of moray eel occurred in Khanh Hoa Province, Viet Nam, with signs indicative ciguatera. The remaining portion was confiscated for identification causative species and responsible toxins. phylogenetic study based on COX1 identified as Gymnothorax javanicus Bleeker (1859). Out 17 marine lipophilic toxins (MLPs) that were analyzed using LC-MS/MS, only Pacific ciguatoxin-1 (P-CTX-1) detected moray’s flesh at 1.30 ±...
A fatal neurotoxic poisoning case happened in Khanh Hoa province 2020 after eating a certain number of marine gastropods, later identified as Nassarius glans, one the common gastropods Vietnam. As remaining causative food incident, 62 specimens were collected to examine tetrodotoxin toxicity individual variation and frequency toxic by using HILIC/MS-MS analysis. 100% studied exhibited (556 ± 821 MU/g) beyond regulatory level consumption (10 for puffer(fish) recommended Japan extensive...
The study was carried out to investigate lipid and protein oxidation of herring (Sardinella gibbosa) that treated with (2.5% w/v) sodium acetate at 4oC. After 3, 6, 9, 12 days, were evaluated by indications such as pH value, peroxide (PV), thiobarbituric acid-reactive substances (TBARS), protease enzyme activity sulfhydryl. results showed that, from 6.33 ± 0.005 7.42 (p < 0.05); PV 1.73 0.31 7.13 0.5 (mEq/kg) 0.05), TBA 53.3 0.28 μmol MDA/kg 207.4± 0.47 0.05). Protease reduced 0.323–0.175...
Zoanthid is a potential natural resource with many biological activities, such as antioxidant, antiviral, anti-inflammatory, and cytotoxic activity. Therefore, this study aimed to evaluate the antioxidant activity of 70% ethanol crude extract dichloromethane fraction from Zoanthus vietnamensis. The total polyphenol content extracts were 19.36 ± 1.37 24.95 0.63 mg GAE/g extract, respectively. DPPH free radical scavenging capacity increased slightly low high concentration. IC50 values reached...
