This research study about how to minimize contamination of raw materials. The bulk of the vegetable is a vegetable commonly used in food.
Pulsed Light (PL) technology is an alternative to thermal treatment for killing pathogenic and spoilage microorganisms in foods, including bacteria, yeasts, molds, and viruses.
The treatment consists in applying a series of very short, high power pulses of broad spectrum light. Xenon , flash lamps emit an optical spectrum that covers a range of wavelengths from the UV cut off of the envelope material (about 180 nm) to IR (around 1100 nm)
Food disease is caused contamination in chicken eggs plant, which is the problem we have to think of something new. In order to reduce the contamination of pathogenic microbial. such as Sanitizers or surfactant.
The combination of PL and 1000 ppm of SDS was found to be more effective than other treatments (ranging from 0.2 to 1.0 CFU/g and from 0.1 to 2.6 CFU/g, for stems and leaves, respectively. which reduced the E. coli O157:H7 populations dip inoculated on the stems and leaves of green onions by 1.4 and 3.1 log10 CFU/g
To decontaminate Salmonella on green onions using not only PL combined with single concentration of SDS, but PL-Tween 80 and PL-SDS with concentrations from 10 ppm to 1000 ppm.
To evaluate Salmonella survival population and quality of green onions right after treatment and during 15 days storage at 4 ºC in order to meet the consumers' needs of fresh and safe food.
