Zogale (Moringaolifera) as a functional ingredient: A review on its nutraceutical properties and food applications

Abstract

Moringa oleifera, also called zogale, is grown and harvested as a tiny and middle-sized tree in different parts of the world. It has various industrial applications, such as medicine, food, and cosmetics. M. oleifera tree is known as a miracle tree containing essential nutrients that could play a significant role in human nutrition. Based on its chemical composition and nutritional properties, it can be used to overcome malnutrition, particularly in breastfeeding mothers and infants. Different parts (leaves, peels, seeds, and flowers) of the Moringa tree are good sources of phenolic compounds, essential amino acids, vitamins, proteins, and beta carotenes, which can play a regulatory and functional role. The proportion of bioactive components is dependent on the source and variety of the plant. The flowers, seeds, and leaves of this plant have also been used in different food applications. This review highlights the reported knowledge relevant to the use of M. oleifera as a food fortificant and therapeutic agent based on its prominent biological activities and the presence of phytochemicals. In a nut shell, the leaves, peels, seeds, and flowers of the Moringa tree are potential sources of different phenolic compounds, which act as anti-inflammatory, antidiabetic, neuroenhancer, and anticancer. There is a dire need for planned and wellstructured experimental designs to deliver possible future applications of this tree.
