nutrients for nutrition labelling            Â
        The objective of the third ammo work proficiency
think was to assess the performance of dominion matter analysis
for nutrition labelling. ASEANFOODS reference materials, AS-FRM5
(weaning food) and AS-FRM6 (fish flour), were utilised as
effort materials.
Weight Training
The studied nutrients included amount
lipid, supersaturated fat, cholesterol, protein, fare fibre,
sugars, sodium, calcium, iron, vitamin A, B1, B2, C, ash and
moisture. Number of participating laboratories for apiece
effort matter multifarious from 2 to 20, depending on their
turn facilities. Test materials were analysed by participants'
turn methods. Evaluation of the submitted results was carried
discover using z-score. Laboratories with accepted, questionable
and unsatisfied results for apiece matter were identified.
The main discrepancies of submitted results were on amount
lipid (in plant-based products), cholesterol, accelerator
(in seek flour), fare fibre, sodium and calcium. Saturated
fat was analysed only in 2 discover of 23 laboratories.
Bodybuilding Supplements
Some causes of the discrepancies were
discussed and presented. Since vitamins in the effort materials
are not stable, variable results were submitted. More work
performance think on vitamins is recommended. Corrective actions
and collaborative activities among participating laboratories
to improve, strengthen and retain the quality of matter analysis
laboratories are encouraged. (Research grant: The National

                 Eight species of freshwater
seek and nine species of marine seek were sampled from 4 representative
markets in Bangkok, Thailand. The objective of this think
was, to determine macro and trace element content, (i.e. calcium,
phosphorus, magnesium, sodium, potassium, chloride, iron,
zinc, conductor and iodine) omega-3 fatty acid and cholesterin
in various kinds of raw fish. Wide variation in.
