Multimistura is an alternative dietary supplement
- high nutritional value- low cost- destined mainly to undernourished children - formulated with several ingredients- use of alternative ingredients- preference for locally available products
Multimistura
• May be formulated using different raw
materials
• Flexibility to produce according to
• Regional availability
• Nutritional requirements of a given
population
Multimistura• Recent studies carried out at LRi/CENA/USP
• Composition assessment of different
• Formulations
• Constituents
Findings
• Large variations among nutrient
concentrations
• Possibility to produce different formulations
• Fulfill specific nutritional requirements

• Extremely positive cost/benefit
Example• Recommended dose of a multimistura for 1-3
year old children = only 10 g/day
• Very low cost

STUDY OF CHEMICAL ELEMENTS IN MULTIMISTURA AND ITS INGREDIENTS
Why using neutron activation analysis?
Neutron activation analysis:
- is a multi-element capable technique- does not need sample dissolution- can be performed at a high metrological level
RELIABLE RESULTS!
Neutron activation analysis was recently approved by CCQM/BIPM as a primary method
The President said that although the CCQM had not discussed the list of ‘potentially primary methods’ during recent years, it was recognised that NAA had claims to a similar status to that of the five methods listed originally by the CCQM and that NAA will be added to that list.
CCQM Primary Methods
• Isotope Dilution Mass Spectrometry• Coulometry• Gravimetry• Titrimetry• Determination of Freezing Point Depression• Neutron Activation Analysis
