Natural compounds and their potential use in stored grain treatment: A review1 1 Research developed at Universidade Federal dos Vales do Jequitinhonha e Mucuri, Campus JK, Diamantina, MG, Brazil

Compostos naturais e seu potencial emprego no tratamento de grãos armazenados: Uma revisão

ABSTRACT

Grain production is steadily increasing; however, the static storage capacity remains inadequate in Brazil. The lack of proper facilities and the precarious and inadequate storage conditions lead to post-harvest losses due to factors interacting with the grains, causing their deterioration. Chemical treatments are commonly used to reverse these effects; however, their replacement with natural substances has been sought due to environmental and human health concerns. The objective of this review was to discuss a sustainable strategy for treating stored grains, focusing on the use of natural compounds with bioactive properties, such as antifungal, antioxidant, and insecticidal activities, with potential for further studies. Natural compounds with useful properties for application in grain storage were outlined. Research on the use of natural compounds in grain treatment is still in its early stages, requiring progress in identifying new promising compounds, understanding the mechanisms of action, and developing and optimizing effective extraction, application, and formulation processes to make the use of these substances viable.

Key words:
sustainability; bioactives; storage; natural products

HIGHLIGHTS:

Using natural compounds for treating stored grains emerges as an eco-friendly and promising alternative.

The recognized bioactivities of classes of natural compounds can be adapted for application in grain storage.

Research on natural compounds in stored grains is still incipient, requiring more tests to make their application viable.
