Fast determination of fish mineral profile. Application to Vietnamese panga fish

The aim of the present study was to evaluate the chemical quality parameters regarding frozen Pangasius hypophthalmus specimens from Vietnam. The proximate composition, pH, ammonia, biogenic amines (BAs), total mercury (Hg), malondialdehyde (MDA), and polyphosphate were determined. The moisture, protein, lipid and ash values were between 83.83–85.59, 12.51–14.52, 1.09–1.65, and 0.76–2.38 g 100 g−1, respectively. Fraud by excessive polyphosphate addition was detected in 30% of the samples whereas Hg above the recommended limit was observed in 50% of the samples. With regard to compounds from the degradation process, low concentrations of individual BAs and pH values were found in this study and ranged from 5.88 to 6.18, except for samples with polyphosphate >1 g 100−1 (pH > 7.00) were observed in the present study. However, ammonia concentration indicated that a degradation process initiated in 80% of the samples (0.12–0.34 NH 3 g−1) and 20% of the samples (1.87–1.94 μg NH 3 g−1) were in an advanced deterioration process. Furthermore, MDA values (1.21–7.88 mg kg−1) suggested some failures, mainly during transportation and/or storage. We concluded that quality control measures must be implemented on the Pangasius production chain to improve the quality of products provided to consumers worldwide.

“…Recent research also indicates that Vietnamese pangasius is very low in the heavy metals arsenic, cadmium, lead and mercury (Ruiz‐de‐Cenzano et al . ). In addition to heavy metals, POPs linked to pangasius in the media, such as polychlorinated biphenyls (PCBs), polychlorinated dibenzo‐p‐dioxins and dibenzo‐p‐furans (PCDD/Fs), have never been notified for pangasius in the RASFF.…”

“…The apparent safety of pangasius is also supported by public health 'counterclaims' that the species is relatively low in mercury, an environmental contaminant especially present in predatory fish compared to other fish species, and therefore a recommended healthy option (DHHS 2014). Recent research also indicates that Vietnamese pangasius is very low in the heavy metals arsenic, cadmium, lead and mercury (Ruiz-de-Cenzano et al 2013). In addition to heavy metals, POPs linked to pangasius in the media, such as polychlorinated biphenyls (PCBs), polychlorinated (2009), who found that levels of these POPs and of organochlorine pesticides (OCPs), polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane diastereomers (HBCDs) and perfluorinated compounds (PFCs) are all very low in pangasius; often even below the limit of detection, and the lowest of all levels in the species of farmed fish tested (including salmon, trout and tilapia) (Budiati 2010).…”

Mass media reports suggest that pangasius (Pangasianodon hypophthalmus) is ‘full of poison’ because it is able to survive in the ‘heavily polluted Mekong River’ and contains pesticides and veterinary treatment chemicals. However, most of these claims are not substantiated with scientific evidence. To assess the safety of pangasius consumption, a full toxicological risk assessment was performed. The results obtained were compared to toxicity claims made in a selection of media reports. Information on contaminant levels encountered in pangasius was collected from the EU Rapid Alert System for Food and Feed (RASFF) database. The toxicological risk assessments do not support any of the toxicological risks suggested in the media. Next, the maximum pangasius consumption that would be considered safe was estimated on the basis of the highest levels of the toxic contaminants reported in Vietnamese pangasius by RASFF and the safety thresholds for the contaminants. The maximum amount of the recalled fillet that could have been consumed without any adverse effects amounted to between 3.4 and 166.7 kg day−1 (lifelong for a 70 kg adult) in the case of pesticide contamination and between 0.613 and 303 kg fillet day−1 in the case of preservatives and antibiotics. It is concluded that consumption of pangasius available on the European market does not pose any concern for the health of the consumer. The analysis presented in this study illustrates that publicly available independent information could help consumers to develop their own well‐informed opinion about food safety issues.

“…For the quantification of the macrominerals, an extract was obtained from the complete digestion of the sample in sulfuric acid and high temperature (350 -375° C). The microminerals were analyzed from extracts from samples of acid digestions under controlled temperatures, with nitric acid (120° C) and perchloric acid (180 -190° C), Total iron (Fe 2+ + Fe 3+ ) (Ruiz- de-Cenzano et al, 2013). To perform the measurements, a model AA 12/1475 atomic absorption spectrometer was used.…”

This study aimed to determine the mineral composition, fatty acid profile, omegas and lipid quality indexes in the visceral fat residues of tambaqui (C. macropomum). Three pieces of visceral fat were collected from 20 fish weighing 1.10 ± 0.10 kg, which were homogenized and sent for compositional analysis. Minerals were determined by AOAC Official method 969.23 and 968.08. The fatty acids were grouped to calculate the ∑PUFAs/∑SFAs fatty acids ratio and the proportion of polyunsaturated fatty acids ∑PUFAs (n-6/n-3), atherogenicity indixes (AI) were calculated, thrombogenicity (TI), and ratio between hypocholesterolemic and hypercholesterolemic fatty acids (HH). Mineral elements were found, 0.68 ± 0.015 mg/100g of total iron, 159.16 ± 14.32 mg/100g of Na+, 63.90 ± 5.11 mg/100g of K+, 10.28 ± 0. 62 mg/100g of Ca2+and 7.31 ± 0.58 mg/100g of Mg2+. As for fatty acids, 40.10% of SFAs, 38.10% of MUFAs and 21.80% of PUFAs. The calculations indicated significant values of omegas, 3, 6, 7 and n-7. There were ∑PUFAs/∑SFAs ratios of 1.84 and ∑PUFAs(n-6/n-3) of 6.22, with an AI of 0.50 and a TI of 0.93 and HH of 2.16. The 1.0 ± 0.10 kg tambaqui visceral fat residues can be evaluated as having high nutritional value, in addition to being a viable option for oil extraction and inclusion in animal feed.
