In the present study, a novel flow injection on-line fiber fabric sorptive extraction (FI- FFSE) platform was developed, in order to take advantage of the benefits of FPSE technique in automatic mode. For this purpose, a microcolumn packed with a sol-gel coated fiber fabric medium, the poly-dimethylsiloxane (PDMS), incorporated into a FI-SPE system, was presented for the first time. This configuration provides insignificant backpressure, resulting in high loading flow rates and shorter analytical cycles. The on-line formed complex of metal with sodium diethyl dithiocarbamate (DDTC) was...

Fresh water fishes are one of the most important source of animal protein in Cambodia. Their average consumption is estimated to be 34 kg/per capita/per year. This represent the 80% from the total consumption of aquatic organisms in the country. Almost 30 % from this amount is represented by processed fish (smoked or salted). Fishes are valuable not only for their protein content, but for the fat as well. However, their fatty acid profile is rarely reported. Thus the aim of the study was to evaluate fat content and fatty acid profile of the seven fish species (Micronema bleekeri,...

Intervention programmes are one of the ways how to educate children and adolescent in rational nutrition and healthy lifestyle and to improve their dietary habits. They can be an important tool in prevention of health problems related with nutrition such as childhood obesity or development of osteoporosis. The purpose of this work was to evaluate effectiveness of rational nutrition and healthy lifestyle intervention programmes for children and adolescents up to age of 18. The effectiveness of six selected intervention programmes was evaluated by questionnaire survey at schools which have...

Reference Material (RM) also used as Proficiency Test (PT) materials were developed for trace metals including lead, cadmium, copper and iron in drinking water where 28 to 31 local laboratories participated in the PT scheme. The PT material was characterized for homogeneity and stability. Reference values were determined using double isotope dilution Inductively Coupled Plasma – Mass Spectrometry (ICP-MS). The PT was organized by the Industrial Technology Development Institute (ITDI) in the Philippines in accordance with ISO/IEC 17043:2010.

Reference materials (RMs) were developed for contaminants such as histamine in canned tuna and benzoic acid in mango juice. The RMs were found homogeneous and stable for at least six (6) months. For the reference value assignment, a candidate higher order method like isotope dillution (ID) technique - Liquid Chromatography-Triple Quadrupole Mass Spectrometry (LCMSMS) was applied. These characterized matrix RMs relevant to food safety issues were also used in PT schemes organized locally to help in the dissemination of measurement traceability to international system (SI) of units.

Mycotoxin contamination due to toxigenic fungi occurs frequently in various food commodities. These can have serious human and animal health risks. In the Philippines, dried fish is widely distributed and are considered as an important commodity due to its availability in the market, ease of processing and cheapness. Testing of these market food products ensures food and consumers safety. This study therefore evaluated the occurrence of aflatoxin-producing Aspergillus from Philippine dried fish products found on its local markets. Thirty-one samples of eleven types of dried fish products...

A highly selective molecularly imprinted polymer (MIP) was synthesized by precipitation polymerization and was used as sorbent material for solid phase extraction (SPE) of salbutamol (SAL) in poultry meat. The MIPs’ performance for the selective extraction of SAL in meat was optimized and compared using commercial SPE. A linear calibration curve was obtained with R > 0.99 for HPLC. Recoveries of SAL using HPLC for meat spiked samples were greater than 90 %. The LOD and LOQ obtained by HPLC were 0.08 µg/g and 0.25 µg/g, respectively.

The phenomenon of antibiotic resistance, that appears increasingly alarming worldwide, has renewed the interest in the study of many natural extracts with antimicrobial properties, such as honey. Even if several honeys have been approved for clinical using, there are some obstacles for therapeutic applicability of honey in medicine, and not only. The variability of antimicrobial activity of different honeys and the incomplete knowledge of the involved antimicrobial compounds are the major ones. The aim of this study has been to define the antimicrobial profile of hydro-alcoholic extracts...

Iodine is an essential trace element for the synthesis of thyroid hormones, important for pregnant women and children. Clinical studies in Portugal have demonstrated the existence of a generalized deficiency in iodine of pregnant women and with school-age children particular severity in the archipelago of Azores. Foods are the main iodine source. Thus, in this work we report the characterization of iodine in foods produced and consumed by population from Azores and continental Portugal. Samples of dairy products, fruits and vegetables from both regions were selected. In total, 110 samples...

Saffron is an invaluable medicinal crop. Saffron-specific phytochemicals have been well studied, yet the whole compositions and their variations remain to be clear. We analyzed six saffron products from different countries, farming methods and food/drug classes through metabolomics with a computational analysis system (Categorical Mapper). Total 5310 compositions were found, of which 3153 were identified, including 545 lipids and 257 drugs. High precision mass spectrometry and accurate identification are essential for assessment of food safety and medical applicability.
