Researchers at the Beijing University of Chemical Technology have developed yeast that produce human gelatin. Gelatin is a part of the skin that, if I understand it correctly, helps to preserve its texture and cohesiveness. It has many uses and is important in cuisine for helping to shape Jell-o, marshmallows, and other such things. Up to date, gelatin has normally been derived from the skin and bones of cows and pigs. These researchers have inserted human DNA into yeast so that they produce the variety of gelatin that is produced by the human body and thus is found in human skin and bones.
Do you fancy a jelly baby made from human DNA?
This may sound like science fiction, yet a new technique for making gelatin from human DNA is attracting “increasing interest from research and industrial circles”, according to a new study by scientists from the Beijing University of Chemical Technology. The paper, published recently in the Journal of Agriculture and Food Chemistry, revealed that successful experiments had been carried out in which human genes were inserted into a strain of yeast to “grow” large amounts of recombinant (genetically engineered) human gelatin.
New Method for Making Human-Based Gelatin
July 14, 2011 — Scientists are reporting development of a new approach for producing large quantities of human-derived gelatin that could become a substitute for some of the 300,000 tons of animal-based gelatin produced annually for gelatin-type desserts, marshmallows, candy and innumerable other products

FibroGen is the only producer of highly purified, fully characterized recombinant human (rh) collagens and gelatins intended to replace similar animal- or human-derived materials currently used in a variety of medical, pharmaceutical, and consumer applications. FibroGen has sold its products to over 100 institutions since introducing them to the market five years ago.http://www.fibrogen.com/collagen_gelatin
Gelatin is an essential ingredient in gummy snacks and marshmallows, not to mention vaccines and drug capsules. Manufacturing it is a messy, inconsistent process, but now scientists can create perfect gelatin with human DNA. The only obstacle seems to be our own squeamishness.
