Abstract

Nutraceuticals are food or food products that possess various health benefits and are
considered as functional food or biologically active phytochemicals which have seen a surge
in demand around 50-70% in the past decade [1]. With an increasing trend of healthy and fit
life there is an inclination towards natural and organic products, especially, food and
supplements adjuncts to synthetic products and drugs for treatment of diseases; hence,
there seems to be a huge market potential for nutraceuticals. These are imperative in
subside the burden on the healthcare system and are of great monetary success due to their
desirable therapeutics outcomes.
Mostly the nutraceutical are extracted from fruits or plant based products directly, however, it
could also it extracted from food waste: the waste from different stages of production such
as bran of plants, pulp of fruits, stems and seeds are residues remaining after extraction of
juice, oil, starch and sugar which makes a large proportion of waste products as they are
inedible, yet a rich source of nutrients and vitamins. The hidden cost of food wastage
exceeds the food production cost. It is reported that food wastage in these forms cost the
economy around $20 billion every year. The agricultural industry contributes around 12% of
total waste, moreover in India every year after harvesting season a larger part of agricultural
land is burned which results in high level of air pollution. If we could utilise these residues in
making various supplements, we could easily reduce copious food wastage every year,
in-fact could produce a health beneficial substance, There are some researches in which
proanthocyanidins- an nutraceutical finding application in various products- was extracted
from grape seed, which was waste product of grape juice [2].
The pivotal point in development of a nutraceutical is extraction of nutrients and vitamins
from the source, and when it comes to extracting from the food waste the process is a notch
complex. This review article is based on analysis of various extraction process employed by
the industries in order to extract nutraceuticals and how to this could be employed to extract
nutraceutical supplements from food waste, then elucidating on some of the nutraceuticals
along with their application and usage for treatment of diverse disease.
By studying different extraction methods, focused only on green extraction technologies- we
came to conclude that varied substrate calls for varied extraction methods. For extraction of
nutraceuticals from food waste, it requires segregation of the waste, sorting, fermentation in
optimum condition and extraction after which the final product obtained is purified,
concentrated and formulated. The type of extraction process to be used is researched on lab
scale then it is upscaled. The idea is to obtain the health beneficial supplements from these agriculture waste like crop residue and bran, food processing waste, which often not utilised
and make their way to open landfills or dumping ground where its organic nature causes
further environmental hazards. This will bring down the capital spent on discarding food
waste and simultaneously will reduct the environmental problems encompassing it.
