The video discusses the development of a milder onion by vegetable growers in England, which is low in the acid that causes eye irritation and strong taste. Research indicates that both the type of onion and the sulphur levels in the soil affect the onion's acidity. By selecting sweet onion types and growing them in low-sulphur soil, the Super Sweet Onion was developed. This project took three years and aims to make onions more palatable for raw consumption. With 300 tons ready for supermarkets in Britain, there is potential for a lucrative export market. Additionally, a grading system is being developed with Liverpool University to help consumers choose onion strength.
