Abstract
By-products of fruits and vegetables from food processing industry have
recently enormous concern because of their pharmacological properties and
great nutritional approach. These food processing by-products serve a cocktail
or a soup of phytochemicals with health promoting properties. These are claimed
to possess many reusable substances of high value and can be money-spinner
if they are appropriately utilized. This chapter articulates that by-product of fruits
& vegetables have a potential to be used as a functional agent in cosmetics,
medicines and functional food application either as raw material for secondary
processes, as operating supplies or as ingredients of new products.

protective and antimutagenic activities. Te purpose of this chapter is
to emphasize the potential of food processing residues as a source of
functional compounds for new products.
Phytonutrients
Phytonutrients, within the context of natural health and nutrition,
has come to refer to certain bio-active plant chemicals that humans
eat and have or may well have signifcant positive efects on human
metabolism. Most phytonutrients are not essential for life, but more
and more they appear to be essential for optimal health and longevity.
Tey therefore may properly be classifed as micro-nutrients, along
with vitamins and minerals. Te technical classifcation of the major
groups of phytonutrients found in our diets includes: terpenes,
amines, organosulfurs, phenols, polysaccharides, and organic acids.
One food can contain several classifcations of phytonutrients. For
example, an orange contains Terpenes (carotenoids and limonoids)
and phenols (bio favonoids). Briefy, the major groups and sub-
groups of phytonutrients and how they may contribute towards
optimal biological function are as under:
The terpenes
Terpenes are the powerful antioxidants for cancer prevention
and cardio-vascular disease. Terpenes are any of various unsaturated
hydrocarbons, found in essential oils and resins of plants and may be
categorized as:
a. Carotenoids: Carotenoids are fat soluble group of naturally
occurring plant pigments of yellow, orange and red spectrum.
Carotenoids function as potent antioxidant and immune potentiators.
Tese are considered membrane antioxidants due to their reactivity
with singlet oxygen. Diet rich in carotenoids are linked with a
decreased risk of heart disease, cancer, and degenerative eye diseases
such as macular degeneration and cataracts [3]. Tey may be diferent
type and occurs in diferent type of plants such as Alpha- carotene,
Introduction
Te modern life style and growing health concern have led to an
increase in the demand for food and food products, which provide
health benefts beyond the crucial nutrition. Natural products
obtained from medicinal and food plants are used as a prominent
source in primary health care since long time. Rapidly growing
body of literature covers the role of plant secondary metabolites
and their eventual efects on human health. Nowadays human being
are gradually more conscious of diet related health troubles and
demanding natural ingredients which are expected to be safe [1].
Large quantities of by-products from fruits & vegetables are discarded
every year at food processing plants resulting from the production,
preparation and consumption of food. Tese by-products represent
a major disposal problem. Food processing residues are those end
products of various food processing industries that have not been
recycled or used for other purposes. Industries simply dispose of
these byproducts by dumping, burning or land flling. Tis is neither
good for the environment, nor is a sustainable behavior if we are to
preserve the earth for the future generations. Serious environmental
problems emerge by these residues, such as water pollution,
unpleasant odors, explosions, combustion, asphyxiation, vegetation
damage and greenhouse gas emissions.
Tus the problem of disposing food industrial waste is becoming
grave. Proper management of these wastes is both a regulatory
requirement as well as an economic necessity. Research show that
these by-products are promising sources of compounds which
may be used because of their nutritional and medicinal properties.
Researchers have shown a strong correlation between the therapeutic
properties of these residues and their health promoting or disease
preventing efects [2]. It has been evident that by-products are good
source of various phytonutrients with a wide range of pharmacological
actions which includes antitumor, antiviral, antibacterial, cardio
