Abstract
This study focuses on the development of nanocapsules loaded with
Tagetes minuta
essential oil (TEO-NC) for milking management in sustainable dairy systems. The nanocapsules were prepared by nanoprecipitation, and their physicochemical properties were evaluated for 60 days at 4°C and 25°C. Antimicrobial and disinfectant activities were evaluated in the presence and absence of organic matter and on contaminated surfaces, such as rubber, stainless steel and ceramics. TEO-NCs had an average particle size of 266.67 ± 18.28 nm, polydispersity index (PdI) Staphylococcus aureus
was 50% (v/v). The disinfectant activity of TEO-NCs (100 and 50%, v/v) was demonstrated against
Pseudomonas aeruginosa
in the absence of organic matter after 5, 15 and 30 min. Disinfectant activity against
S. aureus
was demonstrated after 15 and 30 min (100%, v/v). In the presence of organic matter, the disinfectant activity of TEO-NCs (100%, v/v) was effective only against
P. aeruginosa
. Similarly, disinfectant activity of TEO-NCs against
P. aeruginosa
was demonstrated after 15 and 30 min on the three surfaces tested. Our results highlight the potential of
T. minuta
essential oils, a natural product, which, when combined with nanocapsules, results in a potential alternative for teat disinfection in milking management, especially in the control of environmental mastitis.
