Controlled atmospheres preserve white onion quality, revolutionizing storage methods.
White onions were stored in different atmospheres to see how it affects their quality. The controlled atmospheres helped preserve the onions better than regular storage. The onions in controlled atmospheres had less pungency, lower microbial load, and maintained their color better. The treatment with 1% O2 and 1% CO2 was more effective than the one with 3% O2 and 5% CO2. Controlled atmospheres can help keep onions fresh for longer periods.
