Test-it™ Introduction

Our lives are inseparable with cooking oil. Every day we consume cooking oil through stir frying, sauté, deep frying and dressing our food. Not only does it act as a medium for heat delivery, cooking oil also boosts flavour and makes essential nutrients for the human body. Learning to choose the right cooking oil and mastering the proper way of application is extremely important. Scandals outbreak of gutter oil and adulterated oil in recent years induces public fear in cooking oil consumption.

Test-it™ sampled 115 types of cooking oil in the market, analyzed with world leading biological testing technology Testing 2.0. The safety tests conducted in professional testing laboratories shows that 49 gets the Green Fish (Excellence), 23 gets the Yellow Fish (Basic) and 43 gets the Red Fish (Sub-Optimal). Contrary to common believe, the oil perceived as more healthy actually show less favourable results. Olive oil and coconut oil scored less than their counterparts. This also applies to European brands compared to oil from other origins. Expensive oils do not necessarily means safer.

According to World Health Organization and United Nations, choosing the wrong product could cause cancers, infertility, precocious puberty, obesity and neurological disorders. Test-it™ provide clear, direct test reports with lifestyle tips. Equipped with scientific and objective information, consumers can make safer purchasing choices. Stay tuned for more interesting facts.

Test-it™ Reports

Test-it™ Standards

Traditional chemical Test 1.0 and existing regulations only reflect the basic requirements for market entry, not the products’ actual safety for consumption. Test-it™ applies first-in-the-world fish embryo toxicity (FET) test technology (Testing 2.0), enabling an effective and thorough examination on both acute and chronic toxicity in the tested products (effective up to several thousands of known toxicants to humans). We test and classify global products into three categories (Red, Yellow and Green Fish) through a comprehensive test system and scientific statistic analysis. We provide clear, direct test reports with lifestyle tips. Testing method varies with products. For the cooking oil test, the transgenic medaka embryo testing for chronic toxicants, zebrafish embryo testing for acute toxicants and ingredients check are applied.

Good performance under screening of acute toxicity, chronic toxicity and ingredients. Consumers can rest assured that the products are safe for purchase.

Meets the safety baselines under screening of acute toxicity, chronic toxicity and ingredients. Consumers are recommended to purchase with caution.

Below standard under screening of acute toxicity, chronic toxicity and ingredients. Consumers are recommended to purchase with extra caution.

Test-it™ Discovery

1、Coconut oil, olive oil, flaxseed oil and rapeseed oil shows less favorable results.

The results of olive oil and coconut oil (often perceived as healthy alternatives) are below average in this test. Among the 5 tested coconut oil samples, only 1 (20%) obtained Green Fish. 2 (40%) obtained Yellow Fish and 2 (40%) obtained Red Fish.

Among the 44 tested olive oil samples, only 7(19.15%) obtained Green Fish. 7(19.5%) obtained Yellow Fish and 29 obtained Red Fish.

Adulteration is the possible cause. It had been uncovered by the media that vast majority of Italian oil (80%) were adulterated. 35% of olive oil in China are imported from Italy. According to our test, the results of Italian oil are below average.

2、European Cooking Oils are the least favorable among all the origins.

3、Expensive oils are not necessarily safer .

The median price of the 115 samples is: 86.40 HKD/L.

One third falls in the price range of 50 HKD/L : 30 Green Fish, 10 Yellow Fish, 4 Red Fish.

One third fellas in the price range of 130 HKD/L: 13 Green Fish, 8 Yellow Fish, 10 Red Fish.

The Most expensive oil costs 140 times of the cheapest oil.

The cheapest oil costs 14.78 HKD/L, the most expensive oil costs 2,084 HKD/ L.

4、Limitation of cooking oils tests in existing regulation .

The standard for cooking oil tests under the existing regulations : BaP, total aflatoxin , acid value, peroxide value, total polar material, heavy metals: As, Cd, Cr, Hg, Pb, Sb, Sn.

Yet the existing regulations failed to reflect the following harmful substances that could potentially be found in cooking oils:

Toxic lipid oxidative derivatives,Pesticides ,Phyto toxins,Preservatives.Test-it™'s world leading technology Testing 2.0 can cover the above harmful substances.

5、In this sampling test, we purchased two expired oil samples from a store. One of them obtained Red Fish, which indicates high toxicity. Its toxicity is worse than some of the known gutter oils.

Test-it™ Tips

Methodology

Conventional chemical test 1.0 and the basic regulations only reflects the basic requirement for a product’s market entry. The mission of Test-it™ is to further improve product safety with world leading technology Testing 2.0. Though horizontal analysis in similar products, Test-it™ provides consumers with information and data for better consumer choices. Products are categorised as Green Fish, Yellow Fish and Red Fish according to test results.

Test-it™ has developed a high standard as a third party consumer goods evaluation platform. Developed by an experienced research and development team and an advisory board of toxicology experts from 12 countries, Test-it™ references from the global standard of China, EU, the U.S., Japan, WHO and OECD. With the application of fish embryo toxicity (FET) test technology (Testing 2.0), The standard of Test-it™ could be higher than the existing regulations.
