Pesticides are substances or chemicals used to kill pests, both in the form of plants, insects, and other animals in our environment.
But, washing with water alone is not sufficient to remove pesticides. This is caused by pesticides that are absorbed into the flesh.
As a result many people are switching to choose organic foods on the pretext of safer for consumption. But no doubt the price is more expensive than regular fruit types.
Studies published by the Journal of Agricultural and Food Chemistry recommend using baking soda mixed with water to remove pesticides in fruits.
Reported from Business Insider, if both are mixed it will produce sodium bicarbonate which is able to eliminate two types of pesticides, namely thiabendazole and phosmet.
Thiabenndazole and phosmet itself is a type of pesticide that absorbs into the skin and flesh of fruits.
The study conducted experiments on apples soaked for 12 to 15 minutes until no pesticides were left on the apple. The apple is then washed again with water to remove residue from baking soda.
Nevertheless, it is estimated that there are about 100 types of pesticides that can stick to the fruit that is able to absorb up into the cell equilibrium and difficult to remove. Therefore further research is still needed.
Material engineer from Purdue University, USA, Lia A. Stanciu revealed that peeling apple skin can remove pesticide residues. However, apple skin contains flavonoids, phytochemicals, and antioxidants that are good for the immune system.
Even so, Stanciu suggested that fruit washing processor tools be given sodium bicarbonate to reduce pesticides.
