| Resumo: |
The chia seed (Salvia hispanica L.) is rich in unsaturated fatty acids (omega-3 and omega-6) fibers, proteins, carbohydrates, minerals, antioxidants and vitamins, and due to its functional properties, has been increasingly consumed by the population. However, the seeds can be contaminated by the presence of fungi. The objective of this study was to analyze the fungal contamination of chia seed sold in Campo Mourão, PR. Eight samples were analyzed by direct plating seed technique with surface disinfection and no surface disinfection. Analyses were performed in triplicate. The results were expressed as percentage of fungal contamination. All samples had fungal contamination and the samples that have undergone surface
treatment had reduced fungal growth. The predominant genera of fungi were identified, and were Aspergillus, Penicillium, Mucor and Rizhopus. |
