What are the common emulsifiers in life

Introduction: many of the foods we eat contain emulsifiers What are the common emulsifiers in our life? Are emulsifiers harmful? Next, let's have a look with the small edition of Baibai safety net Emulsifier is a kind of organic compound which can make immiscible liquid form stable emulsion They are all surface active substances, which can reduce the interfacial tension between liquids and make the immiscible liquids easy to emulsify During emulsification, the dispersed phase is uniformly distributed in the continuous phase in the form of very small liquid beads The emulsifier forms a film or double electric layer on the surface of these liquid beads to prevent their mutual condensation and maintain the stability of the emulsion Emulsion is a heterogeneous system The most common is the oil in water emulsion with water as the continuous phase and insoluble organic liquid as the dispersed phase There are also oil-in-water emulsions with water as the dispersed phase and water-insoluble organic liquid as the continuous phase In order to prepare stable emulsion, single component emulsifier or several emulsifiers can be added at the same time What kinds of emulsifiers are commonly used in our life? The products approved for use in China include span, tween, sodium stearyl lactate calcium, sodium stearyl lactate, triglyceride, propylene glycol fatty acid ester, sugar cane ester, soybean phospholipid, lauric acid monoglyceride and more than 30 kinds of Chinese liquid emulsifiers Not many, the existing products are: liquid monoglyceride (i.e monooleic acid glyceride), soybean phospholipid (phospholipid with decolorization and hydroxylation), Tween series products, monocaprylic acid (or caprylic acid) glyceride and other products Is it harmful to eat emulsifier? We should use a dialectical point of view to look at this problem Emulsifier is used under the national designated standards, and it is harmless for people to eat it However, if the dosage exceeds the prescribed limit, it may cause the problem that people's stomach and intestines are not suitable for liver Therefore, when eating emulsifier, we must pay attention to the dosage If we don't know whether it exceeds the standard, we can use food safety test Instrument detection, we should also know more about food additives at ordinary times, which can help us correct the problem of food emulsifier Editor in charge: he xianrob
