Presence of some mycotoxins in peanuts from harvest to storage

Abstract

In this study, aflatoxin and cyclopiazonic acid levels on the second crop of peanuts collected from 102 different research areas of Osmaniye and Adana, Turkey in 2016 was determined from harvest, drying, pre-storage and storage. During the periods of the research, it was found that aflatoxin levels in 86 out of 102 contaminated samples were ranged from 0.2 to 2177.2 ìg/kg. However, cyclopiazonic acid, another mycotoxin investigated in this study has not been found in any of the 102 peanut samples. When aflatoxin contamination compared in different periods; it was observed that the aflatoxin level in storage and drying (97%) periods were found to be higher than the harvest (66%) and pre-storage (71%). The statistical analysis showed that significant differences in the aflatoxins in drying, and storage periods. Therefore, for preventing grains from aflatoxins damage control management strategies need to be improved.

Mycotoxins in Maize and Implications on Food Security: A Review

“…poor harvesting practices, improper storage, processing and less than optimal conditions during transport and marketing can also contribute to fungal growth and proliferation of mycotoxins (Santiago et al 2015). Lavkor et al (2019) reported an increase in aflatoxin levels during drying and storage compared to the pre-storage period.…”

“…use of resistant maize varieties (Czembor et al 2019); good agricultural and processing practices and favorable storage practices that suppress the growth and development of the causative fungi. Early detection and possible exclusion of fungal contaminated grains are essential control measures for ensuring storage longevity and food safety (Lavkor et al 2019;Orina et al 2017). However, once mycotoxins contamination occurs, this approach might not eliminate mycotoxins thus necessitating the use of postharvest detoxification procedures.…”
