Multivariate Analysis of Fruit Antioxidant Activities of Blackberry Treated with 1-Methylcyclopropene or Vacuum Precooling

Effects of 1-methylcyclopropene (1-MCP) and vacuum precooling on quality and antioxidant properties of blackberries (Rubus spp.) were evaluated using one-way analysis of variance, principal component analysis (PCA), partial least squares (PLS), and path analysis. Results showed that the activities of antioxidant enzymes were enhanced by both 1-MCP treatment and vacuum precooling. PCA could disc...

FT-IR Spectroscopy in Medicine

Infrared spectroscopy has been widely applied for the characterisation of various substances. Due to its sensitivity to the chemical information and architecture of the molecule, infrared spectroscopy can play an important role in new applications such as in the life-science field and not only in the traditional fields of physics and chemistry. Spectroscopic techniques are simple, reproducible,...

Biological Control of Postharvest Fruit Pathogens in Papaya

First of all, since the area of biological control is so vast, I will be restricting my talk to the area of biocontrol of postharvest fruit pathogens. Fungicides are a primary means of controlling postharvest diseases. However, as a result of public concern about the presence of synthetic chemicals in our food supply and environment, several fungicides have been banned by the U. S. Environmenta...

Structural Analysis of Hirudin Using FT-IR and FT-Raman Spectroscopic Techniques

FT-IR and FT-Raman spectra of hirudin have been recorded from the native solid hirudin. The conformation of the molecule has been discussed on the basis of IR and Raman data. It has been concluded that hirudin molecule has a mixed a-helix and random coil conformation.
