f. Food Processing Industry

The application of nanotechnology in food processing is
carried out with the aim of improving the taste, texture, color, flavor,

and consistency of food ingredients; increase absorption of healthy
nutrients and supplements; improve various properties, barriers,

and antimicrobials of packaging materials; developing nano sensors
to detect contaminants as well as pathogenic bacteria; improve

traceability and monitoring of the condition of foodstuffs during

storage and transportation.
The addition of nanocapsules containing tuna fish oil

containing Omega-3 in food ingredients that can be broken and
dissolved with the help of a microwave. This technology can hide the

taste and smell of tuna fish oil.
Another application example is the development of a catalyst

for refining cooking oil made from nano ceramics to reduce

unwanted rancid odors.

2. Relationship between Nanotechnology and Green

Chemistry

Through nanotechnology, materials can be designed in such a

way as to obtain the desired properties and materials without wasting
unnecessary atoms. So that the limbar at the molecular level is reduced

because all the reactions become the final product. Remember that one
of the principles of green chemistry is atomic economy. This

nanotechnology is closely related to the principle of green chemistry
number 2 which is to maximize the economic value of atoms. If all the

reactants can be completely converted to products, it can be said that the

reaction has an atomic economic value of 100%. Therefore, it can be
concluded that nanotechnology is one of the applications of green

chemistry principles for the purpose of environmental preservation.
