How healthy are your fresh fruit and vegetables?
Fertilizers that contain necessary elements for plant growth are used for cultivating fruits and vegetables. However, misuse of production technology, usage of prohibited fertilizers, pesticides and chemicals, as well as an increased level of fertilizer concentrations in the soil can all result in a serious damage to your health. Of all the substances that are transferred to the soil from fertilizers, nitrates are one of the most harmful if consumed in excess. Continuous intake of food with a high nitrate content may lead to an elevated risk of serious diseases.
Are you being exposed to dangerous agricultural chemicals? Many farmers apply too much fertilizer. This can result in unsafe levels of fruit nitrate and vegetable nitrate content. It’s especially dangerous to children.
nitrates and nitrites in fruit and vegetables: The risk to human health
Most health conscious people know about the dangers of pesticides in fresh fruit and vegetables. Few are aware that fresh fruit and vegetables expose them to dangerous nitrates.

What Experts Say
In order to obtain maximum health benefits from consuming the recommended intake of vegetables, it has become more and more important to ensure that the fruit and vegetables that we put into our bodies and those of our loved ones are safe by reducing nitrate and nitrite exposure as much as possible.
- Priscilla Lau, Hong Kong dietitian
To ensure the maximum health benefit taken from vegetable and fruit, whether the food we eat is up to the nitrate and nitrite safety standards is more important than before.
- Liyi Lau, Hong Kong Nutritionist
Nitrates occur naturally in our fruits and vegetables, a small amount isn’t harmful, but our body converts an excess of nitrates into nitrites. And when nitrites get into the stomach, the acidic conditions may cause it to form nitrosamine, which is carcinogenic and may be seriously harmful to our health. According to the World Health Organization we currently ingest 10 times more nitrites than recommended amount. Eating fresh fruits and vegetables is a good thing, but you can’t see the healthiest by just looking at the outside.
- Dr. Robertusvan Schie, Dutch medical scientist
There Is A Difference
Our company dedicates ourselves to changing the quality of life and protecting us and our children from the infringement of harmful impurities, nitrates and nitrites. As a result, a revolutionary new food safety testing equipment – Greentest, has been developed, which allows detecting fruits and vegetables cultivated improperly and evaluating the concentration of nitrates. It helps us satisfy our “greenlife” desires to rub the lamp.
Now you can identify unhealthy fruit and vegetables with this portable food safety testing equipment, especially for fruit and vegetable nitrate detection...
Protect yourself and protect your family
Simply insert the probe into your sample
Easy-to-read test results in just 3 seconds
It only takes 3 seconds to check the health of your fruit and vegetables
How It Works?
Greentest works by measuring the electrical conductivity of the fruit or vegetable matter being tested.
Lower resistance = higher nitrate content
The presence of nitrate ions in organic matter measurably increases conductivity. This measurement differs according to the ion concentration and cell structure of the fruit or vegetable under test.
Calibrated through extensive testing
Our scientists developed the Greentest nitrate content protocols by using a mass spectrometer to determine nitrate levels in a large number of fruit and vegetable specimens.
Testing a range of specimens under laboratory conditions allowed us to establish normative levels for various fruit and vegetable species.
A high degree of accuracy
The results were applied to test algorithms which have been coded into the Greentest device. The device has been extensively back-checked against specimens that were subsequently tested with a mass spectrometer.
This food safety equipment is certified to be more than 90% accurate according to third party testing.
This is more than sufficient to produce a valid assessment of nitrate content.

What Our Customers Have Told Us
Greentest is an effective way to help me make sure I’m getting the quality of food I’m paying for.
- Kitty, gourmet food lover
Greentest is great for checking the freshness of produce at the markets. It gives me an edge when sourcing and helps the vendors understand I’m serious about quality.
- Sandy, chef
Greentest is useful for anyone concerned about what they eat. The science is solid and the machine appears to be highly accurate
- Petra, nutritionist
This health test is cool. It doesn’t test your health though, it tests the health of your fruit and veggies. Now I know whether that potato belongs in my mouth or in the compost.
- Kimberly, vegan
I get the best prices for my veggies from the farmer’s market. Greentest helps me show customers how much care I take with my crops.
- Stephen, market gardener
I recommend this food safety equipment to any patient who has issues with excessive nitrate intake.
- Mike, dietician
This thing makes me feel like I got a diagnostics lab in my pocket. All I gotta do is stab a piece of fruit or vegetable with the Greentest and read it like a traffic light. Green for go eat, amber for watch out, and red – stop don’t eat that stuff!
- Alex, systems analyst
I found another way we can avoid those nasty nitrates. Until we found Greentest there was no way to know if fruit and vegetables were adding to my daughter’s nitrate problem.
