The invention relates to a method and system for treating a liquid beverage using an electromagnetic field comprising AC and DC components to achieve antioxidizing, promoting fat/lipid burn metabolism, reducing alcohol toxic effect and improving drinking mouth feel and flavor. In particular, the invention relates to methods and systems for applying the DC biased time-varying frequency pulsating electromagnetic wave in a pulsating manner to the alcoholic and non-alcoholic beverages. The method and the system of the invention are able to result in various treatment effects for the beverages simultaneously.

A method of making a porous, dehydrated food product comprises subjecting a food product to pulsed electric field treatment to form pores in the cell membranes of the food product, freezing the treated food product, and exposing the treated frozen food product to microwave radiation in a vacuum chamber at a pressure that is less than atmospheric and at which the boiling point of water is above 0 C., causing the frozen food product to thaw and water to evaporate to produce the porous, dehydrated product. The process is faster than freeze-drying and consumes less energy. The pulsed electric field treatment does not result in structural damage to the product, despite the thawing of the frozen product during the drying process.

A method of freezing and preserving a frozen object includes: controlling a temperature in a container to keep the temperature at a predetermined freezing temperature and applying an AC voltage to the frozen object such that a weak current (1 A or more and 1,000 mA or less) flows through the frozen object in the container; and while applying the AC voltage to the frozen object in the container, freezing and preserving the frozen object at a predetermined freezing temperature for a predetermined preserved period or more.
