Hypothesis
Can oxygen-reducing atmospheres effectively degrade aflatoxins and improve the safety and quality of packaged shelled Brazil nuts during storage?
Conclusion
Ozone treatment, with or without vacuum, was the most effective method for degrading aflatoxins and improving the safety and quality of packaged Brazil nuts.
Supporting Evidence
- Ozone treatment was the only method that completely degraded aflatoxins in the nuts.
- All other treatments only stabilized or inhibited microorganism growth without degrading aflatoxins.
- Vacuum treatment combined with ozone improved the sensory attributes of the nuts.
- CO2 also contributed to the quality of the nuts but was less effective than ozone.
Takeaway
Using special gases like ozone can make Brazil nuts safer to eat by getting rid of harmful substances and keeping them fresh longer.
Methodology
The study involved treating shelled Brazil nuts with ozone, carbon dioxide, and oxygen absorber pads, and then analyzing the effects on aflatoxin levels, fungi control, and lipid stability over two months.
Potential Biases
Potential bias in the selection of treatment methods and sample batches.
Limitations
The study focused only on specific oxygen-reducing methods and did not explore other potential treatments.
