Abstract
Turmeric oil has been known as possessing antioxidant and antimicroorganism activities, especially growth inhibition of fresh fruit spoiling microorganisms. Turmeric oil was used in traditional medicine for decades in Asian countries for disease treatment. Chitosan is a natural carbohydrate polymer, can be produced by deacetylation of chitin, with various features as biological compatible, biological degradation, adherent membrane, antimicroorganism and harmless, so is used for application investigation in biopharmacology and function food. Chitosan were processed into nanoparticles and is used as a vehicle for drug delivery and gene transformation. For making natural product in posthaverst fruit preservation as an alternative for commonly used chemicals, antibacterial activity of nanochitosan (NCS), NCS with turmeric oil (TDN) and mixture of NCS, TDN and siver nanoparticles was determined. Recieved results showed that NCS, NCS-TDN and NCS-TDN-NB have not only growth inhibition activity against Bacillus cereus, and Listonella damsela, but also bactericidal activity. Combination of NCS, TDN and NB significantly enhances their antibacterial activity
