The international team of researchers revealed how to cut onions without tears, Metro reports. According to a study published in the PNAs scientific journey, the secret is in the right to use the knife.
Years of research have shown that tears are not from the smell of onion, but from microscopic droplets of its juice, which turn into aerosol and fall on the mucous membrane. The material contained in onions, Sin-Propanetal-S-oxide causes a chemical reaction to contact with the cornea, which leads to irritation and tears.
Scientists have found that the amount of emergent emergent depends directly to the severance of the knife and the cutting techniques. Blut blades squeeze the onions, increasing the excrement of juice, while fast slashing movements create more annoyances. The best results were received with sharp knife and delicate, measured cutting movements.
However, the common method of freezing the onions before cutting the onions did not show its significant effectiveness in reducing tears. The authors believe that the research can also have practical application in the food industry to improve the working conditions of cooks and kitchen workers.
