Phenolic Compounds in Agro-Industrial Waste of Mango Fruit: Impact on Health and Its Prebiotic Effect – a Review

Abstract

The fruit processing industry generates huge amounts of waste annually, causing severe environmental problems. Mango processing produces around 20 million tons of wastes from the non-consumed fraction, mainly peels and seeds, which constitute 30-60% of the fruit weight. However, various phytochemicals found in these residues have been implicated in preventing cancer and also cardio-metabolic and gastrointestinal diseases. Particularly, phenolic compounds hold a promising potential to be utilized as modulatory agents of the human gut microbiota (prebiotics-like actions). This review article mainly discusses the effect of phenolics from mango wastes on gut microbiota modulation and its beneficial repercussions for human health. Moreover, it also discusses the importance of phenolic compounds of mango peel and seed kernel residues, their extraction, identification, and quantification.

“…This waste includes mango seeds, which are a sustainable source of phenolic compounds. [17][18][19][20] The mango seed kernel representing about 14-22% of the whole fruit and its disposal need to be diverted to edible products. 15,21 Different types of important bioactive compounds can be obtained from mango kernel for pharmaceutical formulations and human healthcare.…”

“…In several cases waste has been released without any treatment, creating environmental pollution and causing economic losses. This waste includes mango seeds, which are a sustainable source of phenolic compounds 17‐20 . The mango seed kernel representing about 14–22% of the whole fruit and its disposal need to be diverted to edible products 15,21 .…”
