Abstract
Nanoscience is an emerging technology today with great application in different fields. Biocatalysts design,
identification of different bacterial strains, monitoring the quality of food by different biosensors, food packaging with
smart systems, active, intelligent and nano-encapsulation of bioactive food compounds are examples of some of
these applications in the food industry. In this paper, some topics related to the potential of nanotechnology in the
food industry are updated. In addition, some concerns about nanotechnology application in this popular industry are
also discussed.

Introduction
Food, food-biocatalists and bioprocessing industries face great
challenges in order to develop and establish systems to develop high
quality, safety foods, as well as feeds and other industrial goods,
environmentally acceptable and in a sustainable way [1]. Recently, an
ideal immobilized biocatalyst using calcium alginate beads was
described for the industrial-scale production of invert sugar for food
and beverages industry [2,3]. However, despite the advantages of
currently used immobilization materials like calcium alginate,
nanostructure materials exhibit, a higher catalytic eiciency over other
traditional materials, greater surface reaction activity, strong
adsorption ability, and thermal stability [4-6]. On the other hand, the
use of nanostructure carriers increase life cycles of the biocatalyst thus
allowing its reuse and reducing the bioprocess cost [7]. All these
features are highly desired for industrial purposes. hermal stability
increment was described in the case of Candida rugosa lipase
immobilized on polylactic acid nanoparticles [8]. On the other hand,
keratin, a non-food applied enzyme, also improved its stability by the
use of a nanoscaled support [9]. According to these reports, we can
assume that nanomaterials large surface area provides a better matrix
for enzyme immobilization, improve the enzyme loading per
nanoparticles mass unit and its catalytical properties. Not only the
enzyme ield with application in food has pointed to nanotechnology,
the food and beverage industry has also been pointed to nanomaterial
applications. According to some authors, it is a newly emerging
technology, predicted to continually increase [10] since more than 400
companies worldwide develop diferent applications of
nanotechnology in food and food packaging [11]. Some institutes
dedicated to the nano-market research for food and beverages,
estimated that it will grow to $6.5 billion in 2013, $1 trillion by 2015
[12], and will grow with a compound annual growth rate (CAGR) of
12.7% to reach about $15.0 billion in 2020 [13]. On the other hand,
other economic studies carried by other institutions like the European
Institute for Health and Consumer Protection, postulates that the use
of nanomaterials in the food packaging market will reach $20 billion
by 2020. his paper contributes to a broader understanding of the
main applications of nanotechnology in food ields like biocatalists and
food and feed industries by openly discuss these issues using balanced
information and scientiic indings in a simple technical language.
Materials and Methods
We are not attempting to provide a comprehensive summary of
analytical techniques used for nanotechniques applied to diferent
research ields, thus, the goal of this report is to present a brief review
of methods developed in our own and other laboratories and lessons
gathered from our experiences that may be useful to other researchers.
For this review, we used peer-reviewed, published papers that were
identiied by electronic searches in Medline and Google Scholar. he
search strategy included diferent combinations of key words such as
nanotechniques, enzyme immobilization, nanotechnology in foods
and feeds, nanomaterials, nanotechnology concerns, etc. No
language limits were applied. Search period was not longer than 10
years. In addition, we performed manual searches in reference lists
from speciic own or other published papers to ind additional pioneer
and older studies that could have been overlooked by the electronic
search.
Equipments, microorganism and fed-batch fermentation, cell
disruption to get enzymes of interest, preparation and storage of
calcium alginate beads, enzyme assays for free and immobilized
enzymes, protein and carbohydrate analysis were conducted as
described in our previous papers [2,3].
Nanotechnology Today
he use of new technologies based on nanomaterials created great
expectation and interest since the past century [14]. Nanotechnology is
considered nowadays an interdisciplinary ield that works tightly with
other scientiic disciplines like physics, chemistry, biology as well as
engineering. Working at the nanoscale level is exiting because this
nano level ofers diferent physical, chemical, and biological properties
of structures and systems to those displayed by its macro-scale similar
due to the interactions of individual atoms and molecules. his means
