Greentest is a device for quick testing of nitrate content in fresh fruits, vegetables and meats.
Of all the substances that get into the fruit and vegetable fertilizers, nitrates are most damaging when they exceed the normal amount. Nitrates and nitrites are added to the meat products during processing to reduce bacteria and highlight color. Continuous intake of large quantities of foods containing nitrates can lead to an increased risk of bowel cancer, methemoglobinemia, diabetes, Alzheimer's disease and poisoning by nitrates.
Concentrations of the various salts in the tested products, whether containing salts with essential nutrients, and salts which are detrimental to health. Greentest helps to detect the ion concentration of such substances as: chlorine (Cl), sulphate (SO4), nitrate (NO3) and nitrite (NO2). It is calibrated to display only the exact amount of nitrite. Nitrate salts that accumulate in high concentrations due to improper cultivation of fruits and vegetables, are a very serious threat to human health. Based on the results, which are compared with international levels of safe concentrations, Greentest recommends whether this fruit or vegetables suitable for consumption or dangerous to health.
