4.  Nanotechnology or “nanotech” focuses on the characterization,
fabrication, and manipulation of biological and non-biological
structures of matter
 Refers to components at nano-scale with process or processes
used in the manufacture and/or bio-fabrication of size less than
100 nanometers
 A component of macro scale single and multidimensional
products
 Structures on this scale have been shown to have unique and
novel functional properties

5.  Because of their ‘nanosize’, these materials exhibits
exceptional feature to develop innovative products.
 Applications right from advancements in trending technology to
development of unconventional and never-thought-before
products.
 Research and development projects aim at amendments of the
persisting molecular features at the atomic level.

a) high reactivity
b) enhanced bioavailability and bioactivity
c) adherence effects and surface effects of nanoparticles

6.  The estimated growth of world population from 6.7
billion in 2006 to 9.3 billion by 2050 directly implies the
increased world food needs.
 Advancements in food and agriculture sector ,thus, is a
major concern guiding the research in the field of
nanotechnology and its applications in both these major
sectors.
 Direct impact on production, growth, reception,
processing and storage until its consumption.
 Major areas are increased production of agricultural
products, water treatment and decontamination and food
processing, storage and biosecurity.

7. 1) Promising applications of nanotechnology in foods includes:
 Enhancement of activity and bioavailability of nutrients
 improvement of organoleptic features
 better consistency of food matrix
 new packaging development
 food traceability, safety and monitoring during transport and
storage
 new purification techniques and removal of unwanted substances to
reduce environmental side-effects
2) Forms a natural part of food processing and conventional foods.
3) The advantages of being simple, cost-effective and environmental
friendly and contributing to the economy.

8.  The types of material produced at the nano scale can be in:
a) one dimension (very thin coatings, nanoemulsions)
b) two dimensions (nanowires, nanofibers or nanocapsules,biofilms)
c) three dimensions (nanocarriers,
nanoparticles such as very fine
powder preparations)

25.  The health implications of use of nanotechnology warrants
attention of food regulations.
 The release of nanoparticles and nanotubes into the
environment must be avoided.
 The EU regulations have recommended that for the
introduction of new nanotechnology, specific safety standards
and testing procedures are required. In US, nano food and
packaging is regulated by USFDA, while organic chemicals
are regulated by EPA.
 In Australia, nanofood additives and ingredients are regulated
by Food Standards Australia.
 New Zealand follows FSANZ, under the Food Standards
Code.

26.  Helps to pay more attention on value addition through processing
and nutrition sciences
 To develop a newer and better technology that can be used for
various processes and applications at both industrial as well as
commercial levels with focus on food safety
 Reduces the pressure on environment, increases efficiency in
production systems and demands of the population
 In addition to the technical and scientific advancements to food,
regulatory considerations (safety/ toxicology and environmental
impact), economics and consumer acceptance of nanotechnology
will ultimately direct its contributions in food applications.
