You're probably washing your apples wrong, according to one study

Washing with ordinary tap water removed none of the chemicals that had penetrated the skins of the apples, while a commercial bleaching agent, Clorox, only had limited effectiveness.

Previous research reveals baking powder breaks down pesticides due to its highly-alkaline pH, which causes the chemicals to fragment into harmless molecules.

The use of pesticides can help increase crop yield, but concerns over their potential effects on human health have been raised over the years.

Lead author Dr Lili He from the University of MA, said: "Pesticide residues may remain on agricultural produce, where they contribute to the total dietary intake of pesticides".

Removing stubborn stains from pans - shake a generous amount into pans, before adding hot water and washing up liquid.

Researchers in the United States carried out laboratory tests of different methods used to remove two common pesticides from apples. They at that point washed these apples with three unique fluids: tap water, a 1 percent preparing pop/water arrangement, and a U.S. - EPA-affirmed business fade arrangement frequently utilized on create.

All the cleaning methods mostly removed pesticides from the surface, they said. After 12 minutes, 80% of thiabendazole was removed, while 96% of the phosmet was removed after 15 minutes.

Mapping images showed that thiabendazole had penetrated up to 80 micrometres deep into the apples; phosmet was detected at a depth of only 20 micrometres.

Researchers noted peeling the apples can also prove effective in removing any pesticides, but you will lose key nutrients found on the skin.

The research is reported in the Journal of Agricultural and Food Chemistry.

The baking soda solution was the most effective at reducing pesticides.

'The standard post-harvest washing method with bleach solution and a two-minute wash did not effectively remove these pesticides'.

Dr He said: "The use of pesticides in agriculture has led to an increase in farm productivity.However, pesticide residues may remain on agricultural produce, where they contribute to the total dietary intake of pesticides".
