Why doesn't ice-cream melt at room temperature? Is it because of magic or the food additives?
What you put in your mouth is not only a tasty scoop of ice-cream, but also various emulsifiers, stabilizers and thickeners …

Test-it™ Introduction

Nothing cools you down better than a bowl of ice-cream. For its unique and tasty chill, the cold dessert is popular in both summers and winters. But what are the safety risks hidden behind the delicious treat that gives satiety and quenches the heat?

To find out the truth, Test-it™ selected 29 most popular ice-cream products in the market and joined hands with professional laboratory to perform safety tests using the world leading bio-testing technology Testing 2.0. Based on the test results, it rated 12 products as Green Fish (Excellent), seven products as Yellow Fish (Basic) and 10 products as Red Fish (Sub-optimal).

The results showed that Swiss brands had the best safety performance. In theory, food additives do not pose health threats when their use is in compliance with the standard, but if mixed with other additives or ingredients, they may produce toxic compounds and compromise food safety.

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

Ice-cream used to be exclusive to the elites and nobles.

In 2014, global sales of ice-cream exceeded USD50 billion, of which the Chinese accounted for one-third.

In winters, ice-cream sellers in the north don't have to store their goods in freezers.

Curry-flavored ice-cream is designed for the Indians, who love curry to the bits.

A Japanese company developed ice-cream that doesn't melt when left for an hour at room temperature.

In order to enhance the production process and cater customers' needs, it is inevitable that food additives are added to ice-cream.

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 ice cream 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.

Findings of Test-it™

1. Price battle: expensive ice-cream products don't have outstanding safety performance.

Samples are classified into high-priced, mid-priced and low-priced ones and the results are as follows:

Among the 29 samples collected, the most expensive one costs 30.4HKD/100ml, which is around 12 times of the cheapest one that costs 2.7HKD/100ml. The average price of the samples is 20.3HKD/100mL.

Despite having a higher percentage of Green Fish than mid-priced and low-priced samples, high-priced products also have a higher percentage of Red Fish, hence their safety performance was not particularly outstanding.

Since ice-cream is popular in all seasons and China accounts for one-third of global consumption, it is important for consumers to choose products that are safe for their health. In this regard, the Green Fish Recommendation List has a huge responsibility to safeguard people's well-being!

2. Product origin battle: Swiss brands are the safest.

Test-it™ conducted test on brands mainly from Hong Kong, Japan, Switzerland, the USA and New Zealand.

Swiss brands are found to have better safety performance than brands from other regions when comparing products from different places.

3. Food additives may not be safe even when they aren't used in excess.

The main ingredients of ice cream include milk, water, sugar and eggs. Its texture is attributable to food additives.

【Review】In August 2017, a customer in Australia bought an ice-cream sandwich manufactured at a local supermarket and left it on the lawn for the birds and insects. As it turned out, not only did the ice-cream sandwich stay unmelted after five days under the sun, no animals or insects went near and ate it. Experts are of the view that gelling agents must have been added to the ice-cream product. In this regard, the manufacturer admitted to the media that they put emulsifiers to the treat to create a honeycomb-like structure, which helped to slow down melting.

In the 29 samples under the test, the most common additives are guaran (found in 22 samples), locust bean gum and carrageenan (both found in 15 samples), which are popular food stabilizers and thickeners. When used appropriately in accordance with the national requirements of different countries, these ingredients will not cause direct health risks.

However, current test regime assesses only the risks of the most common or potential hazardous and toxic substances, but not other chemicals that may arise or the combined toxicity effects.

【Gelling agents】Carrageenans are extracted from various seaweeds and widely applied as a “natural” food additive. The World Health Organization, the European Food Safety Authority and the PRC government have imposed limits on its use in baby foods. The European Food Safety Authority even banned the use of carrageenan in food for infants under 4 months.

Xanthan gum is a polysaccharide produced from the fermentation process by bacteria and is added as a food thickener or stabilizer. According to the 2017 re-evaluation report of the ESFA, xanthan gum may contain heavy metals such as lead, arsenic, cadmium and mercury. In view of such, it is planned to revise the limit of heavy metals in xanthan gum so that it will not become the major source of food poisoning.

In theory, food additives do not pose health threats when their use is in compliance with the standard, but it doesn't mean that they are safe. If mixed with other additives or ingredients, they may produce toxic compounds and compromise food safety.
