What is technology that use light pulse?

Pulsed light technology (PLT) is an innovative method for the purification and sterilization of food items using very high power, short duration pulses of light emitted by inert-gas flash lamps.

What is pulsed light in food preservation?

Pulsed light is effective for sterilization of surfaces and highly transparent liquids, such as water, and has been successfully used to inactivate bacteria, mold, spores and viruses in various food materials. This technology had been successfully used to inactivate myriad microorganisms in various foods.

What is pulsed UV light?

Pulsed ultraviolet (UV) light technology has emerged as a significant non-chemical and non-ionizing approach to decontaminate food products. Pulsed UV-light is a novel UV-light technology that offers effective inactivation of pathogens on food surfaces within a significantly short period of time.

Which microbial inactivation happens in pulsed UV light processing of foods?

(2013) designed a laboratory-scale PL system consisting a xenon lamp used to produce intense pulsed light (IPL) with an emission spectrum in the range of 200–1100 nm for inactivating Listeria monocytogenes on solid medium and seafoods (Figure 1).

How does pulsed electric field work?

Pulsed Electric Field (PEF) processing or electroporation works by puncturing the cell membrane, whatever the size of cell. The process is targeted, gentle and clean. As a result, we measure dramatic increases in yield and the preservation of pigments, antioxidants and vitamins. PEF makes healthy products last longer.

What are IPL treatments?

Intense pulsed light (IPL) therapy, aka photofacial, is a way to improve the color and texture of your skin without surgery. It can undo some of the visible damage caused by sun exposure — called photoaging. You may notice it mostly on your face, neck, hands, or chest.

How does pulsed xenon work?

Pulsed Xenon technology utilizes a broad spectrum of UVA, UVB and UVC wavelengths delivered in intense pulses every six seconds that damage the pathogen 1 beyond repair.

What is pulsed xenon UV light?

Pulsed xenon ultraviolet (PX-UV) is an attractive alternative to traditional UV methods offering high-intensity pulse germicidal UV. It is emitted in short, high-intensity pulses, possibly requiring a shorter duration of exposure to achieve lethal doses.

What type of light is IPL?

Intense pulsed light (IPL) devices are non-laser high intensity light sources that make use of a high-output flashlamp to produce a broad wavelength output of noncoherent light, usually in the 500 to 1200nm range.

What is high pressure processing?

What is High Pressure Processing (HPP)? High pressure processing allows gentle preservation of food by high pressure without additives or heat. To achieve this a pressure of 6,000 bar – which equals roughly the weight of three jumbo jets acting on a smartphone-sized area – is applied to the products.

What is cold plasma in food processing?

Cold plasma is a novel nonthermal food processing technology that uses energetic, reactive gases to inactivate contaminating microbes on meats, poultry, fruits, and vegetables.
