Biogenic amines (BAs), which are produced naturally due to the decomposition of amino acids, crucial for food industry because its formation is directly related improper storage and presence bacteria. High concentrations BAs can be easily with quality spoilage products this sector. The necessity quickly efficiently quantify these targets makes mandatory use alternatives conventional analytical ...

Aim: The present study aimed to identify factors that influence the consumption of fish and foods that are enriched with omega-3 long-chain polyunsaturated fatty acids (n-3 LCPUFA), in order to inform the development of effective nutrition education strategies. Methods: A cross-sectional, 10-item self-administered survey was conducted to 262 parents of children aged 9-13 years from a regional c...

The incorrect labeling, as well the bioaccumulation of heavy metals in seafood, represent a recurring problem worldwide, not only for natural resources but also consumers’ health. Heavy can be accumulated through food chain and transferred to final human consumer. Despite its toxicology, arsenic does have concentration limit on food, unlike other like cadmium, mercury, lead. Tuna species, with ...

There is a rising global concern with regard to mercury (Hg) exposure among coastal populations. Two communities on the Bay of Fundy (New Brunswick, Canada) were assessed by hair monitoring and dietary methods. Average concentration of total Hg in hair was 0.70+/-0.55 mg/kg (N=91) at Grand Manan and 0.42+/-0.15 mg/kg (N=52) at St. Andrews/St. Stephen. Average daily consumption of fresh fish and...

We describe a PC-based real time machine vision system for the quality assurance of canned tuna at a tin rate over 1,000 tins per minute, allowing the inspection of the tin and its contents, with two main purposes: preventing defective tins from damaging the closure equipment or from reaching the market with a defective closure, and deviating from the production line tins with low quality conte...

A composite electrode was prepared by modifying glassy carbon microparticles with gold nanoparticles (Au-nps) and xanthine oxidase enzyme (XOD) for xanthine (X) and hypoxanthine (Hx) detection. After the optimization of the system for X, the biosensor was characterized for X and Hx. A linearity was obtained in the concentration range between 5.00 x 10(-7) and 1.00 x 10(-5) M for X with equation...
