Whether you’re an avid fan of fried foods or an environmentalist, the exciting news is that air cookers produce significantly less indoor air pollution than other cooking methods.
People spend most of their time indoors, and the quality of the air they breathe in their homes can have critical effects on their health. Cooking emissions are a major source of air pollution in homes because they contain both particulate and gaseous substances.
Indoor air pollution is a growing concern as pollution has been linked to negative health issues such as cancer, respiratory infections, asthma and lung diseases, among others.
However, as our understanding of this alarming situation deepens, we encounter a glimmer of hope for cleaner cooking techniques.
Discovering the advantage of the air cooker
In order to find out the environmental effects of different cooking methods, the research team conducted a comprehensive study that is both laboratory accurate and reflects real, everyday kitchen conditions.
To do this, they took over the dining room kitchen of the University of Birmingham’s prestigious School of Geography, Earth and Environmental Sciences.
At the heart of this vibrant culinary landscape, they decided to test the emissions from five common cooking methods and compare them to those from cooking with an air pressure cooker.
Experimenting with an air pressure cooker
Armed with chicken breasts and cooking utensils, the team began a series of experiments that included pan-frying, stirring, boiling, deep-frying and, of course, air-frying.
They used state-of-the-art laboratory equipment to measure emissions of particulates and volatile organic compounds (VOCs) when using each method.
It turns out that particle concentrations, expressed as peak concentrations in micrograms per cubic meter of air, varied significantly between different cooking methods.
Frying pans took the lead with 92.9, followed by stir frying with 26.7, deep frying with 7.7 and boiling with 0.7. In comparison, air cookers produced at least 0.6 micrograms per cubic meter.
As for VOCs, the story was much the same. Each cooking method was measured in parts per billion, or ppb, with standard frying methods producing a worrying 260 ppb.
Stir frying produced 110 ppb, deep frying 230 ppb and boiling 30 ppb. Once again, air cookers emerged as the environmental winner with only 20 ppb.
After-effect of cooking
The study’s lead researcher, Professor Christian Pfrang, emphasized that various factors – such as the amount of oil used and the temperature of the hob – can affect the level of pollution in cooking.
He emphasized that improvising kitchen ventilation by opening windows or using fans reduces the spread of polluting particles and personal exposure.
Interestingly, the study also considered residual pollution that remained long after the cooking process was over.
Even an hour after cooking, the kitchen had significantly more pollutants, even though each cooking process only lasted about 10 minutes.
Professor Pfrang added that because particles linger in the air for a long time after cooking, continuing to ventilate or leaving exhaust fans on will help prevent indoor pollution from building up, reducing potential spread throughout the house.
Research from the University of Birmingham reflects the environmental benefits of an air fryer. They bring the joy of fried food to the table and minimize our environmental footprint at the same time – one chicken breast at a time.
Broader effects on health and resilience
The results of this study extend beyond the kitchen, highlighting a critical intersection between daily habits and broader environmental and health concerns.
Indoor air pollution is a major factor in respiratory problems, cardiovascular problems and even cognitive abilities, which highlights the importance of cleaner cooking methods.
By reducing particle and VOC emissions, air cookers not only support personal well-being, but also promote a more sustainable lifestyle by reducing energy consumption compared to traditional ovens or hobs.
For environmentally conscious households, incorporating an air fryer into their daily routine is a small but impressive step towards reducing their carbon footprint.
With the growing demand for a healthier and more sustainable life, air cookers act as a practical and easy-to-use innovation that combines comfort with environmentally conscious choices.
The entire study was published in the journal Indoor air.
