Sodium stearoyl-2-lactylate is the sodium salt of stearoyllactic acid ( lactate ), whereby it is a mixture of several components with a large number of by-products.
Manufacturing
The substance does not occur naturally. It is produced in several steps through chemical reactions of stearic , lactic and polylactic acid (stearoyllactic acid) with calcium compounds.
use
Sodium stearoyl-2-lactylate is an emulsifier and stabilizer . It is used in the food industry, primarily as flour treatment agents and stabilization in dairy products used. In interaction
- with gluten it is used to improve the baking properties of flour ,
- with starch , their water-binding capacity is retained longer, so that baked goods stay “fresh” longer, and ultimately it takes care of it
- with the milk proteins for better foam formation .
The unstable substance breaks down into its components in the food. It is considered harmless.
It is approved in the EU as a food additive (E 481) for certain foods (including desserts , liqueurs , various baked goods ) with maximum quantity limits of between three and eight grams per kilogram.
