Emulsion (definition) An emulsion is a mixture of two or more liquids that are normally immiscible. Emulsions are part of a more general class of two-phase systems of matter called colloids. Homemade mayonnaise is an example of an emulsion.
A food emulsifier, also called an emulgent, is a surface-active agent that acts as a border between two immiscible liquids such as oil and water, allowing them to be blended into stable emulsions. Emulsifiers also reduce stickiness, control crystallization and prevent separation.
Some recent work in cell cultures and animals suggests that eating a common type of food additive, called emulsifiers, can harm the gut microbiome, increasing gut permeability—commonly known as “leaky gut.” … The most commonly consumed emulsifier is lecithin, which is present in all plant and animal cell walls. Since leaky gut and SIBO and IBS are all connected, there is some thought that those with gut issues shoule avoid emulsifiers. Emulsifiers are used in many processed foods. Therefore, sometimes I like to make my own mayo when I am having a flare in my IBS or really having some issues. Also, most mayonnaise contains potato starch which can be resistant starch for SIBO.
