Nanotechnology in the food industry could be used to fight against Covid-19 in three ways: 1.It can increase the immunological system because the process implemented herein concentrates vitamins, minerals, fiber, proteins, among others. 2. The products can be preserved for periods longer than 2 years without adding any chemicals. 3. The virus within the product will disappear because the molecular sieves are smaller than the virus (10-10 versus 10-9), and during the dehydration process, if Covid-19 is present in the unprocessed product, during dehydration, the molecular sieves and biopolymers will allow the virus to attach to their surface, thereafter, it is destroyed in the regeneration process when the sieves and biopolymers are placed in an oven at temperatures higher than 250oC. The molecular sieves and biopolymers are used as filters inside a vacuum chamber; temperature and pressure changes tuning, by trial and error until the desired characteristics are obtained are required to fulfill the process. Other advantages include: the system does not use any contaminant substances during the drying process, colour and smells are preserved and concentrated; the discharge is only limited to water vapour. More than 1000 products had been tested over a 12 years’ research. In addition, sub-products development could result from the recovery of wasted material such as toothpaste and calcium pills from egg shells, cosmetics from mangostine and shrimp peels, bromelain from pineapple stems, among others. Whenever sub-products’ development is not possible, the waste could be used for soil improvement by means of composting.
