Why to add emulsifier in milk

Introduction: milk is a kind of dairy product we often drink Its nutritional value is also very high But do you know why emulsifier should be added to milk? Is it harmful to eat emulsifier? Many friends may have a lot to do with these problems Let's introduce it to the big family The emulsifier is a surfactant, which has both hydrophilic and hydrophobic groups in its molecular structure Milk is actually an emulsion, which is composed of two or more immiscible liquids (oil and water), with poor stability Therefore, there are many kinds of emulsifier emulsifiers to be added, and their uses are also different Most of the emulsifiers in milk are high-level fatty acid esters, which are non-ionic surfactants Why emulsifier should be added to milk? Bai Bai safety net tells us that emulsification is the function of one kind of liquid to disperse uniformly in another kind of liquid which is insoluble with very small droplets Emulsification is a liquid-liquid interface phenomenon Two immiscible liquids, such as oil and water, are divided into two layers in the container The oil with small density is in the upper layer and the water with large density is in the lower layer If a proper surfactant is added under strong agitation, the oil is dispersed in water to form emulsion, which is called emulsification Emulsifier is the medium for emulsification In the process of milk production, in order to better integrate oil and water, emulsifier is needed to form a uniform and stable emulsion Do not add emulsifier will make milk surface appear a layer of oil, affect everyone's appetite For example, ice cream, coffee partner, salad dressing, mayonnaise and so on, as well as some solid foods with high oil content, such as cake and ham sausage, also need oil emulsification When they are gelled and solidified, oil will not be seen on the surface and will not affect appetite There are also some food systems with more oil and less water The emulsifier is to disperse the water into small drops and distribute them evenly in the oil, typically butter In this way, when we eat it, we won't be affected by the oil on the surface Is it harmful to eat emulsifier? The emulsifier added to our food is approved by the state As long as it is used in normal dose, it is not harmful But if it is used in excess of the dose, we should pay attention to it We can go to the relevant departments to do food safety tester test At the same time, we should also know more about food safety knowledge to help us understand emulsifier dialectically Editor in charge: he xianrob
