Principle：

Electroporation (PEF for short) is an emerging international food research field in recent years. It is a kind of placing complete fruits and vegetables and crushed fruit pulp as electrolytes in a container equipped with two electrodes. A high-voltage pulsed electric field (usually 20-80kV/cm) is applied to the two electrodes. Fruits and vegetables and crushed fruit pulp are subjected to the action of a high-voltage pulsed electric field (electroporation) in a very short period of time, causing the internal tissue structure of fruits and vegetables to change, and the water molecules in fruits and vegetables are arranged in an orderly manner due to the action of electric forces. At the same time, the high-voltage pulsed electric field can change the permeability of the cell membrane, thereby improving the efficiency of fruits and vegetables. Drying rate.PEF can improve the extraction rate of fruit juices, sugars, colorants and other active substances, and significantly extend the shelf life.Diffusion processes, such as removing moisture or marinades from plant or animal tissues, accelerate the absorption of spices and auxiliary substances, thereby saving valuable time in the production process.

Electroporation effect：

Create value by maximizing the effectiveness of natural raw materials.Electroporation can significantly increase yield, freshness and flavor in a variety of foods and applications.

In particular, PEF processing can be used to enhance the mass transfer process in the extraction, pressing or drying of fruits and vegetables.The permeability of meat tissue can be used to enhance the drying, marinating and marinating process.

When PEF is applied to liquids and semi-liquids, the freshness of non-hot foods can be achieved while maintaining the quality and freshness of sensory and nutritional products.

The benefits of high-voltage pulsed electric field on fruits and vegetables after treatment：

Prolapse 20~50% moisture of fruits and vegetables

Improve cutting performance, smooth cutting surface, improve product yield and quality, reduce oil absorption and reduce equipment wear.

Many PEF users report reduced water and energy consumption, a continuous process of inactivating microorganisms at low temperatures.The application of PEF can extend the shelf life while retaining the taste, color and nutritional value of freshly squeezed raw materials

Electroporation system composition：

The PEF system equipment mainly includes five parts: power supply device, pulse generating device (including capacitor and control switch), sample processing room, cooling system, and temperature measurement system.

Application of high voltage pulsed electric field：

1. Food drying: such as vacuum freeze-drying, vacuum frying and drying, microwave vacuum drying, hot air drying, etc.

2. Other liquid food industries: fruit juice, wine, fruit wine, beverages, milk, vegetable oil, etc.
