Properties of milled zingiber officinale rosc (ginger) rhizome powder to coarse, fine and nano sizes and its effects on the storage stability of spent hen chicken / Norhidayah Abdullah

Z. officinale Rosc. (ginger) has been globally used and known to possess
beneficial health properties due to the presence of various bioactive
compounds. However, the poor absorption of these bioactive compounds
is due to low water solubility, large particle size and complex chemical
structure had restricted its bioactivity. The nanotechnology process
has been reported as an advanced technology recently applied in food
materials to increase the water solubility and improve bioactivity of
the active ingredients. However, study on nanoparticle herbs is lacking,
hence this study was conducted with the aimed to investigate the effect
of nanotechnology process on physicochemical properties of nanoparticle
Z. officinale rhizome powder. A study on the effect of this powder as
a marinating agent on the storage stability of spent hen meat was also
conducted. Physicochemical changes were determined using laser
diffraction technique, Field Emission Scanning Electron Microscope
(FESEM), The Fourier Transmittance IR (FTIR) and X-ray diffraction
(XRD). Antioxidant content was estimated by Total Phenolic Content
(TPC) and Total Flavonoid Content (TFC) while antioxidant activity
was performed via ABTS Cation Decolorisation Assay (ABTS), DPPH
Radical Scavenging Activity (DPPH) and Ferric Reducing Antioxidant
Power (FRAP) assays..
