In experimental studies, dried almonds and antimicrobial oils were placed in a high pressure autoclave and the placed samples were treated with high pressure CO2 gas.

Although the developing technology is reflected in the food industry, many foods are produced as fabricated. Although dried cookies are included in this situation, scientists state that dried cookies can be contaminated (Contamination is the presence of an ingredient, impurity, or other undesirable element that spoils or infects the physical body, natural environment, workplace or a material). Now, scientists have developed methods to improve this situation.

High pressure CO2 gases have long been used to clean food from pathogenic bacteria.

CO2 gas and contamination
Germany’s Fraunhofer Institute for Environment and Safety, and Energy Technology researchers met with researchers from Canada’s University of Alberta, and in experimental studies, dried almonds and antimicrobial oils were placed in a high-pressure autoclave and the placed samples were treated with high-pressure CO2 gas.

According to the results, the samples are not only disinfected, but the oils form a coating on the outer surface of the almonds, thus protecting against potential pathogens such as Staphylococcus carnosus and extending the shelf life of the almonds.

It is also stated that the new method does not leave any residue (residue) on the food, is not harmful to the environment and does not require high energy.
