What is L-cysteine, or How Did Duck Feathers Get in My Bread??? L-cysteine (sometimes shown as E920 on food labels) is a food additive often derived from duck feathers or human hair. It is used as a dough conditioner and strengthener, meaning the dough can be stretched out to make a pizza crust, for example. L-cysteine can also help extend the shelf life of commercial breads.
Cysteine is the precursor or reduced sulfur donor of most other organic sulfur compounds in plants. The predominant proportion of the organic sulfur is present in the protein fraction (up to 70% of total sulfur), as cysteine and methionine (two amino acids) residues.he formation of cysteine is the direct coupling step between sulfur (sulfur metabolism) and nitrogen assimilation in plants. This differs from the process in yeast, where sulfide must be incorporated first in homocysteine then converted in two steps to cysteine.
