SUMMARY:
NanoFood, Technology in Food Products, is a startup that produces biodegradable coatings with
nanostructures to increase the shelf-life of fruit post-harvest, it contains two products in its
portfolio: coating with nanostructure of zinc oxide (ZnO) and coating with nanostructure of
chitosan. The technological scale-up process on a laboratory scale progressed from TRL 3 to 6,
formulating a more robust prototype. The nanostructure production process generated a ZnO
nanostructure measuring 347.7 ± 177.34 nm with a PDI of 1 ± 0 and a chitosan nanodispersion
measuring 35.93 ± 4.62 nm. The papayas coated with the prototypes had a lower loss of mass
compared to the control, 11.56% and 10.25% respectively. In the UGBP company, the papayas
had a mass loss of 10.77 ± 1.41 % for zinc oxide and 10.62 ± 2.58 % for chitosan. The papayas
coated with the prototypes showed a lower rate of contamination by phytopathogens and smaller
wounds compared to the control papayas. The technological scale-up process on a pilot scale
progressed from TRL 6 to 8. The investment for the complete implementation of the pilot plant
amounted to R$ 113252.476. The zinc oxide (ZnO) nanostructure produced in the pilot plant using
the unit operations had a hydrodynamic size of 312.05 ± 82.66 nm and the synthesized chitosan
nanostructure 45.28 ± 10.78 nm.
