Pasteurize liquids without the need for heat or chemicals
This company’s PEF (pulsed electric field) pasteurization system does not use heat or chemicals. Suitable for juices, yogurt and other foods that can be pumped, the PEF system does not alter the flavor or consistency of the foods or liquids, the company says. The custom-engineered PEF system employs brief pulses of very high voltage, and can process between 50 and 10,000 L/h. The company says that its PEF system achieves a greater than 5-log bacteria kill and uses less energy than conventional pasteurization technologies because operators have full control over pulse and frequency. — Diversified Technologies Inc., Bedford, Mass.
