Moringa oleifera potential as a functional food and a natural food additive: a biochemical approach.

Several works have shown different aspects of the use of the plant Moringa oleifera. However, few review studies bring an approach to its use in food preparation, specifying its role as a functional food and its use as a natural additive, focusing on food biochemistry and including sensory acceptance and safety. Composed by multiple bioactive substances, Moringa oleifera has the potential to be used as a food additive, mainly as a preservative with the potential to prevent lipid oxidation and other unwanted chemical reactions that lead to product deterioration. Furthermore, it can improve the physicochemical characteristics of food, increasing its quality and shelf life. It also promotes nutritional improvement, elevating protein, mineral, and vitamin levels. Despite this, the sensorial characteristics of this plant result in a low consumer acceptance of the fortified products, which is a problem for the food industry. Apart from inconclusive works, some data involving Moringa's safety are contradictory, resulting in its commercialization prohibition in Brazil in 2019. This review focused on important data about Moringa use to contribute to the literature and to the food industry, describing information about this medicinal plant effects on food products.
