Precautions for emulsifier use

Introduction: with people's attention to health, people are paying more and more attention to the use of emulsifier in food Many people want to know the precautions for emulsifier use, and also want to know whether eating emulsifier is harmful? Let's have a detailed understanding of Baibai safety net Since the 1960s, people began to pay attention to the safety of surfactant use, and strengthened the research on non-toxic, biodegradable non-ionic emulsifier In the food, cosmetics, medicine and other industries, the use of some emulsifiers is limited, and new emulsifiers such as sorbitol fatty acid esters, phospholipids, glycolipids emulsifiers are developed Since the 1980s, people have put forward higher requirements for multifunctional, high purity, low stimulation and high efficiency of emulsifiers, and developed more new emulsifiers At present, the type of emulsion has expanded from traditional oil in water and oil in water to multiple emulsion, non aqueous emulsion, liquid crystal emulsion, hair color emulsion, gel emulsion, phospholipid emulsion and liposome emulsion Emulsifier is the stabilizer of emulsion and a kind of surfactant The function of emulsifier is: when it disperses on the surface of dispersing substance, it forms a film or a double electric layer, which can make the dispersing phase charged, so as to prevent the small droplets of the dispersing phase from coagulating with each other, The emulsion is relatively stable Xiaobian Xiaobian, here, introduces the points for attention in the use of emulsifiers: 1 emulsifiers with different HLB values can prepare different types of emulsions, and 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 if the above mixture is directly added into the water to eat emulsifier? Generally speaking, the emulsifier we eat is the one with strict national standard dosage, which will not be harmful, but it is not ruled out that there are illegal businesses using emulsifier excessively If we use emulsifier excessively, it will affect human health For our own health, we should strictly use it If the content of emulsifier in food safety detector exceeds the standard, we should also pay attention to the little knowledge of food additives and learn more about emulsifier problems Editor in charge: he xianrob
