Resumen:
Edible nano-coatings were applied in strawberry with the end goal of
preserving quality by 21 days of storage at 4 degrees C. The beeswax
solid lipid nanoparticles (BSLN) were prepared by high-energy
homogenization, BSLN had a monomodal dispersion with average particle
sizes of 214-227 nm and zeta potential of -30 mV. Four coatings were
tested: 0, 10, 20, and 30 g/L of BSLN dispersion, all these edible
coatings contained xanthan gum (XG) (3 g/L) and propylene glycol (5 g/L)
and contrasted with strawberries without any treatment. The best
behavior was achieved with 10 g/L of BSLN showing the lowest weight loss
(6.1%), a decay index of (31%), loss of firmness (34%), and Delta E =
11. It was established that a concentration of 30 g/L of BSLN caused
physiological damage. Based on the findings found, it can be said that
nano-coatings with 10 g/L of BSLN-XG are an excellent alternative in the
conservation and to increase of shelf life of strawberry stored in
refrigeration. In the present case, it was 10 g/L of BSL. Highlighting
the importance to evaluate the best concentration in relation to the
fruit characteristics.
