Study Notes
Flash Pasteurization
- Pasteurization method at 71.6°C for 15 seconds.
Ultra-Pasteurization
- Pasteurization method employing 82°C for 3 seconds.
Hot Oil Sterilization
- Some medical professionals use hot oil sterilization at 160°C for one hour to sterilize instruments.
Ultraviolet Irradiation
- Bacteria are often destroyed by UV light wavelengths of 265nm, which damages bacterial DNA.
- UV light's energy wavelength range is 100-400 nm.
- It's often used to decrease air contamination.
Ionizing Radiation
- X-rays and gamma rays can destroy bacteria by ejecting electrons from organic molecules.
