Notes on emulsifier

Introduction: emulsifier is widely used In addition to bread, the yogurt we drink and the ice cream we eat all contain emulsifier So, what are the precautions for using emulsifier? Is it harmful to eat emulsifier? Let's answer these questions Emulsifier is a kind of surfactant with hydrophilic and oleophilic groups Emulsifiers play an important role in food processing, and are widely used in baking products Food emulsifier is a kind of food additive with large consumption The most commonly used emulsifiers for bread quality improver are sodium stearyl lactate, calcium stearyl lactate, diacetyl tartaric acid monoglyceride, sucrose fatty ester, distilled monoglyceride, etc Through the interaction of starch and protein in flour, various emulsifiers form complex complex, which can enhance gluten, improve processing performance, improve bread tissue, and prolong the shelf life Emulsifier is the stabilizer of emulsion and a kind of surfactant The function of the emulsifier is: when it is dispersed on the surface of the dispersing substance, a thin film or a double electric layer is formed, which can make the dispersing phase charged, so as to prevent the small droplets of the dispersing phase from coagulating mutually, and make the emulsion formed more stable What are the points for attention of the emulsifier? Xiaobian Xiaobian Xiaobian introduces you to the following points: 1 emulsifiers with different HLB values can prepare different types of emulsions Choosing the right emulsifier is the basic guarantee for achieving the best results 2 Due to the synergistic effect of the composite emulsifier, the composite emulsifier is usually used, but the difference between the high value and the low value of HLB should not be greater than 5 when choosing the emulsifier "pair", otherwise the best stable effect will not be obtained 3 Before the emulsifier is added to the food system, it should be fully dispersed or dissolved in water or oil to make a slurry or emulsion There are three ways to prepare the emulsion: (1) the emulsifier is directly dissolved in water, and the oil is added under intense agitation (2) The emulsifier is dissolved in the oil phase (heated) and water is added directly Or is it harmful to directly add the above-mentioned mixture to the edible emulsifier in water? In fact, the emulsifier is added to the food to improve the food quality or increase the color, fragrance and taste of the food or for the production and processing needs It is normal to have emulsifiers in food Harmful to human body refers to the amount of additives Therefore, as long as the consumption of emulsifier is not excessive, it is harmless to human body If you are worried about the excessive use of emulsifier, you can check it with food safety detector, and learn more about food safety, which is good for us to know food additives Editor in charge: he xianrob
