Resumen
The in situ effect of microencapsulated 2(3)-tert-butyl-4 hydroxyanisole (BHA) on stored peanuts (Arachis hipogaea) intended for human consumption was evaluated. Peanut were stored unshelled in flexible containers called “big bags” that were made of polypropylene raffia. 100 kg of peanuts were used in each big bag and stored in refrigerated cells (<18 °C) for about 5 months in two different peanut processing companies during 2015/2016 period. Fungal populations, aflatoxin accumulation, BHA residues, acidity and fatty acid profile, sensory analyses, insect damage and environmental factors variation, were evaluated. At the end of the storage period, significant (p < 0.05) fungitoxic effects of the BHA formulation were observed in the order of 30 and 15% for the first and second company, respectively. Cladosporium, yeasts, Penicillium, Fusarium, Alternaria and Aspergillus were the main fungal isolates. No aflatoxins were found for both companies and years evaluated. In addition, taste of the peanuts was not significantly affected (p < 0.05) by formulation used and insect damage was always lower than 3%. However, different levels of BHA were detected throughout the experiment in the two companies, with final levels of 2.5 for the C1 and 275 ng BHA/g peanuts in C2. Formulation did not affect acidity and organoleptic properties of peanuts. These results show that BHA formulation could be used as part of alternative strategy for control of fungal contamination storage period.
