What is the best temperature for onions to lose weight?

  • Weight loss is higher when the temperature is above 35 0 C. Onions are stored at a temperature of 30-35 0 C with a relative humidity of 65-70% but for cold storage, onions are kept under temperature between 0-2 0 C at a relative humidity of 60-70%.

What are the challenges of onion storage?

  • Sprouting and rooting are major challenges of onion storage. Sprouting is controlled by temperature while rooting is controlled by relative humidity. A temperature below 10-25 0 C increases sprouting and the higher the relative humidity the higher rooting occurrence.
