PPoster Session, Thursday, June 17Theme F686 - N11231Nanotechnology and Its Applications in Food Sector1USeval Sevgi KrdarUP P*PMehmet Akif Ersoy University Vocational Higher Education School, Food Processing Department 15 100 Burdur-TurkeyAbstract- In this rewiew summarized the application of nanotechnology relevant to food sector.Nanotechnology applications are expected to bring a rangeof benefits to the food sector, including new tastes, texturesand sensations, less use of fat, enhanced absorption ofnutrients, improved packaging, traceability and security offood products [1]Several applications of nanotechnology are available(Figure 1)UFood ProcessingNanocapsules for improving bioavailability ofneutraceuticals in standard ingredients such ascooking oilsNanoencapsulated flavor enhancersNanotubes and nanoparticles as gelation andviscosifying agents.Nanocapsule infusions of plant-based steroids as areplacement for meat cholesterolNanoparticles that selectively bind and removechemicals or pathogens from foodNanoemulsions and nanoparticles for beteravailability and dispersion of nutrientsAltria, Nestle, Kraft, Heinz and Unilever, as well as smallnanotech start-up companies[4]Nanoparticles are already on the market. An inventory ofconsumer products incorporating nanotechnology identified580 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 andFitness’ which accounted for 61% of the total (Figure 1).These products were further subdivided as: ‘Food’;‘Cooking’; ‘Storage’; and ‘Supplements’ (Figure 3).NanotechnologyUFood Packaging Applicationsmproved packagings(gas and moisture barriers,tensile strenght)Shelf life extention via active packagingNanoadditivesntelligent packagingDelivery and controlled release of neutraceuticalsAntibacterial or self-cleaning packagingMonitoring product conditions during trasportationFigure.2. Nano-productsFigure 1. Potential application of nanotechnology in the food andfood packaging [1,2]Worldwide sales of nanotechnology products to the foodand beverage packaging sector increased from US$ 150million in 2002 to US$ 860 million in 2004 and are expectedto reach to US$ 20,4 billion by 2010[2]. In a surveyperformed by Israel and The USA in march 2006, it wasfound that over 200 manufacturers currently market productsidendified as “nanoproducts”. Approximately 60% of theseproducts were for “health and fitness” and 9% were for “foodand beverage products[3]. The nanofood sector (the termrefers to the use of nanotechnology techniques, materials ortools for production, processing or packaging of food) iscurrently led by USA, followed by Japan and China.However, Asian countries (led by China) are expected to bethe biggest market for nanofood by 2010[4]. It has beensuggested that the number of companies currently applyingnanotechnologies to food could be as high as 400 . A numberof major food and beverage companies are reported to have(or have had) an interest in nanotechnology. These includeFigure 3.
