Aflatoxin in Tunisian aleppo pine nuts
Journal - Association of Official Analytical Chemists
|May 1, 1977
Summary
High levels of aflatoxin contamination were found in Tunisian Aleppo pine nuts, with some samples exceeding 2000 ppb. A popular pudding made from these nuts retained over 80% of the original aflatoxin levels.
Area of Science:
- Food Science
- Mycology
- Public Health
Background:
- Aleppo pine nuts are a common food source in Tunisia.
- Aflatoxins are toxic secondary metabolites produced by certain fungi.
- Food contamination poses significant public health risks.
Purpose of the Study:
- To assess the prevalence and levels of aflatoxin contamination in Tunisian Aleppo pine nuts.
- To investigate the stability of aflatoxins in a traditional pudding prepared from contaminated nuts.
Main Methods:
- Collection of 50 Aleppo pine nut samples across Tunisia.
- Quantification of aflatoxin B1 and total aflatoxins using [specific analytical method - not provided in abstract].
- Preparation of a traditional pudding using contaminated nuts and analysis of residual aflatoxin levels.
Main Results:
- 26 out of 50 (52%) pine nut samples showed high aflatoxin contamination.
- Aflatoxin B1 levels reached up to 2000 ppb in some samples.
- Total aflatoxin levels were as high as 7550 ppb.
- The traditional pudding retained over 80% of the initial aflatoxin content from the nuts.
Conclusions:
- Aleppo pine nuts in Tunisia are a significant source of aflatoxin contamination.
- Traditional food preparation methods may not effectively reduce aflatoxin levels.
- Further research and regulatory measures are needed to mitigate aflatoxin risks in the food supply.
