Instant coffee may contain very little coffee and the energizing effect may be nothing more than a placebo
Study shows instant coffee may cause cholesterol level to shoot up. Besides, strong milky flavor can mean more additives in your drink. Let the Test-it report reveal the truth of instant coffee!

Test-it™ Introduction

Your busy day begins with a sip. Stirring coffee with a spoon, you immerse in the aroma that wakes you up. All trivialities are gone when you are enjoying your dose of caffeine, as what dissolves in the cup is not only coffee powder, but also your temper and stress. That's why we are all fans of the drink.

Test-it™ selected 30 instant coffee products in the market and worked with professional laboratory to run safety test using the world leading biological testing technology Testing 2.0. The test rated 13 products as Green Fish (Excellent), 7 as Yellow Fish (Basic) and 10 as Red Fish (Sub-Optimal).

Among them, instant coffee products of Southeast Asian brands or those produced in the region have noticeable worse quality. For most of the instant coffee products, coffee content only comprises 5%-9%, and the rest is made up of various additives.

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.

Interesting Facts

Coffee beans are originally plant seeds which are blocked from germination and enter hibernation after processing.

For more effective storage of coffee beans, spray-drying technology is applied to make instant coffee.

Thanks to creamer, we can enjoy coffee with creamy and milky texture. Known as the “best mate of coffee”, creamer, instead of dairy products, gives instant coffee the milk-like flavor.

The state allows manufacturers to label “0” for products containing not more than 0.3g of trans-fatty acids per 100mL. However, it doesn't mean that the drink is free from trans-fatty acids.

Statistics show that coffee is the most popular drink among scientists/laboratory technicians, administration and management as well as public relationship personnel. Which means coffee sells the best at where the scientists are!

When men drink coffee, their sperms become more active because of the effect of caffeine in semen.

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 Instant Coffee 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.In terms of product origins, samples of Southeast Asian brands have worrying quality.

2.In terms of origins of raw materials, samples from Southeast Asia still come right at the bottom.

We tested samples of which the raw materials are from East Asia (China, Japan and Korea), Southeast Asia (Vietnam, Malaysia and Thailand), South America (Ecuador and Colombia) and Europe (the United Kingdom and Germany).

Result shows that:

43% of the samples from East Asia are rated Green Fish, 7% Yellow Fish and 50% Red Fish;

only 30% of the samples from Southeast Asia are rated Green Fish, while Yellow Fish and Red Fish account for 40% and 30% respectively. In other words, the region underperforms as compared to East Asia;

Green Fish and Yellow Fish both take up 50% for South American samples;

All European samples are rated Green Fish. What an achievement!

[Coffeepedia] The most ideal environment for planting coffee beans: the best location is between 25°N to 30°S; the optimal temperature is between 15 and 25 degrees and the suitable precipitation is approximately 1000-1800mm; sunlight is essential for growing, but shading is also necessary so that blossoming and bearing of fruit is not hindered by strong light. Coffee beans grow well on soil with good drainage and fertility that contains pozzolana. Location with clam winds at an altitude of 800-1200m is also good for growing coffee.

In terms of place of production, the environment in East Asia and Southeast Asia is better for growing coffee as a whole. However, the Green Fish rate of these regions is lower than that of Europe, where it is less suitable to grow coffee beans.

3.Higher average toxicity of instant coffee

When comparing with the test results of coffee chains, it is found that instant coffee has a higher average toxicity. In other words, chain stores are a healthier choice to get coffee.

4.The instant coffee you are drinking may not be real coffee.

Most samples contain 9% or less coffee while only a few contains 100%. What's more is that food additives such as creamer, emulsifier and stabilizer are used extensively in instant coffee products.

[Review] Yoshihiro MIYAKE, Suminori KONO and other Japanese pharmacists conducted a six-year study on the impact of instant coffee and filter-drip coffee on cholesterol level of Japanese people, where 4,587 people were selected as test subjects. It is found that, while the traditional filter-drip coffee has no impact on cholesterol level, instant coffee significantly increases cholesterol level and low-density lipoprotein. This may be due to the large amount of sugar and creamer added to instant coffee or 3-in-1 coffee products.

A drink with little coffee and a lot of additives has already ruined the rich flavor of coffee. Perhaps the instant coffee in hand is just a cup of instant hot drink.

5.Additives affect coffee quality

Test results of instant coffee samples show that only 29% of cappuccino samples are rated Green Fish, while Yellow Fish and Red Fish take up 14% and 57% respectively.

[Coffeepedia]Cappuccino is an Italian coffee made by mixing equal amount of espresso and steamed milk foam. The traditional cappuccino comprises 1/3 espresso, 1/3 steamed milk and 1/3 milk foam, with cinnamon powder atop.

Instant cappuccino products use significantly more additives than other coffee products, which results in less satisfactory quality.

6.Price may not be a reliable indicator for product safety

The average price of the 30 samples collected is 4HKD/packet.

Among the samples, the most expensive one costs 11.4 HKD/packet, which is 11 times of the cheapest one, which is 1 HKD/packet.

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.
