Can heating ice cream judge the quality of ice cream?
Of course not.
How is the quality of ice cream? We can use the simplest and most direct detection method to conduct detailed laboratory tests on the ingredients of ice cream by drawing a lottery by sampling the products.
What food additives are used in ice cream? What ingredients have been added? Is it harmful to human body? This is the right way.
Instead of using this irrelevant method to test and mislead the masses.
Most ice cream with water as the main raw material in the market melts much faster than ice cream with high milk content, because the solid content is not high, which is inevitably related to the presence or absence of thickener. Ice cream or ice cream is essentially a mixture of water, fat, protein and sugar. In fact, ice cream has melted in half an hour at room temperature, but the products with high solid content have high viscosity, and will still maintain a certain shape after melting, which seems to have not "melted". For example, popsicles only have more than 1 1% solids, and the rest are water, which will quickly become a thin liquid like ice after melting.
At the same time, food additives such as thickener can make the water in ice cream and other solids form viscous substances, and the water is not easily released, so it can keep its original shape relatively well when the external temperature changes, and it does not seem to "melt". However, it is not enough to rely solely on thickeners, and ice cream needs a high solid content. For example, cream containing 35% solids and milk containing 1 1% solids are frozen after adding the same thickener in the same proportion, and the cream sample with the same volume is far more conformal than the milk sample. So it's not that the more thickener, the more difficult it is to melt.
How to choose ice cream?
In fact, most ice creams become sticky after melting. In order to improve the viscosity of ice cream, manufacturers will add a small amount of carrageenan. There are many factors that affect the melting of ice cream. Generally speaking, ice cream with high solid content melts more slowly than ice cream with water as the main raw material.
As for how to choose ice cream, it mainly depends on the ingredient list. Meanwhile, some top brands of dairy products will have better quality and eat healthier.
As for how to choose ice cream, we should not only choose the taste we are interested in, but also pay attention to the production information, product types and ingredient list of ice cream. Generally, dairy products rank high and the quality will be better.
