Abstract- In this rewiew summarized the application of nanotechnology relevant to food sector.
Nanotechnology applications are expected to bring a range
of benefits to the food sector, including new tastes, textures
and sensations, less use of fat, enhanced absorption of
nutrients, improved packaging, traceability and security of
food products [1]
Several applications of nanotechnology are available
(Figure 1)
UFood Processing
Nanocapsules for improving bioavailability of
neutraceuticals in standard ingredients such as
cooking oils
Nanoencapsulated flavor enhancers
Nanotubes and nanoparticles as gelation and
viscosifying agents.
Nanocapsule infusions of plant-based steroids as a
replacement for meat cholesterol
Nanoparticles that selectively bind and remove
chemicals or pathogens from food
Nanoemulsions and nanoparticles for beter
availability and dispersion of nutrients
Altria, Nestle, Kraft, Heinz and Unilever, as well as small
nanotech start-up companies[4]
Nanoparticles are already on the market. An inventory of
consumer products incorporating nanotechnology identified
580 nano-products, and classified them into eight categories
(Figure 2). Of the 580 nano-products, 12% were classified as
‘Home and Garden’ and the largest category was ‘Health and
Fitness’ which accounted for 61% of the total (Figure 1).
These products were further subdivided as: ‘Food’;
‘Cooking’; ‘Storage’; and ‘Supplements’ (Figure 3).
Nanotechnology
UFood Packaging Applications
mproved packagings(gas and moisture barriers,
tensile strenght)
Shelf life extention via active packaging
Nanoadditives
ntelligent packaging
Delivery and controlled release of neutraceuticals
Antibacterial or self-cleaning packaging
Monitoring product conditions during trasportation

food packaging [1,2]
Worldwide sales of nanotechnology products to the food
and beverage packaging sector increased from US$ 150
million in 2002 to US$ 860 million in 2004 and are expected
to reach to US$ 20,4 billion by 2010[2]. In a survey
performed by Israel and The USA in march 2006, it was
found that over 200 manufacturers currently market products
idendified as “nanoproducts”. Approximately 60% of these
products were for “health and fitness” and 9% were for “food
and beverage products[3]. The nanofood sector (the term
refers to the use of nanotechnology techniques, materials or
tools for production, processing or packaging of food) is
currently led by USA, followed by Japan and China.
However, Asian countries (led by China) are expected to be
the biggest market for nanofood by 2010[4]. It has been
suggested that the number of companies currently applying
nanotechnologies to food could be as high as 400 . A number
of major food and beverage companies are reported to have
(or have had) an interest in nanotechnology. These include
