Abstract

Antinutritional Factors (ANFs) are compounds produced by plants as defense mechanisms, and in high concentrations, they inhibit nutritional properties. Reducing these ANFs increases the presence of proteins, antioxidants, and vitamins, which is crucial for optimizing animal feed, particularly in developing countries where traditional methods may be costly. Solid-state fermentation (SSF) has the potential to improve the nutritional quality of animal feed derived from cereals and legumes cultivated and non-commercially cultivated by reducing antinutrients and enhancing nutrient availability. This review also considers the potential of non-native species, including those exhibiting invasive behavior and taxonomic similarity to cultivated varieties, as alternative substrates for SSF. Additionally, SSF highlights the biological properties of ANFs when extracted and utilized for technological and industrial advancements. Solid-state fermentation with lactic acid bacteria could be an effective and straightforward method for reducing these antinutritional factors while simultaneously enriching protein content. The aim is to present solid-state fermentation as a biotechnological tool to reduce antinutritional factors and enhance the nutritional content of legumes and cereals that are not cultivated for animal feed. This perspective contributes to expanding the range of raw materials considered for SSF by including taxonomically related but underutilized and ecologically problematic plant resources.
