EFFECT OF HIGH ENERGY BALL MILLING GRINDING ON PHYSICO-CHEMICAL, MORPHOLOGICAL AND OPTICAL PROPERTIES OF CURCUMA LONGA NANOPARTICLES POWDERS

Curcuma longa nano powder was prepared by high energy ball milling equipment using green synthesis. Green synthesis is the process of synthesizing nanoparticle from biogenic resources based on the fact of its bioactive potential would be less toxic (product & bi-product), environmental safety (eco-friendly and biodegradable) cost effective and easily available to its natural origin. The powder was characterized by X-ray diffractometer (XRD), Scanning Electron Microscope (SEM), Fourier Transform Microscope (FTIR) and Photoluminescence spectrometer (PL).XRD and SEM results shows average crystalline size and grain size of turmeric powder are in nanometer range. Types of functional group and bond character in the nano powder were determined using FTIR. Optical properties of curcumin was includes changes the colour from yellow to red and emission of multicolour peak in visible region. In this approach, eco-friendly, rapid ways large amount of nano powder can be produced. Such nanometric food particles can improve the physicochemical properties of food materials. Since this materials also possess luminescence with nano size and hence may be useful in biomedical applications and pharmaceutical industry.
