| Technological Process | Date of 1st Application | Technique Employed | Base Material Used | Products Obtained | Advantages / Disadvantages |
| Hydrolysis of Animal Proteins | Mid XIX Century | Use of strong acids to breakdown proteins into peptides and amino acids | Slaughter
house waste Milk industry subproducts |
Peptides
and amino acids High content of impurities due to acids used |
Inexpensive. Limited used Rudimentary technology |
| Enzymatic Hidrolysis of Animal and Vegetable Proteins | The decade of 1970 | Disintegration of proteins via enzyme activity | Vegetable
residues Vegetable proteins |
Peptides
and amino acid derivatives Difficult control of the process and its products |
Relatively
inexpensive Danger of alterations within the cell |
| Synthesis via Genetically Altered Micro Organism Culture | 1960 | Activation of micro-organisms capable of synthesizing amino acids | Genetically
manipulated micro-organism: - Brevibacterium - Corinobacterium |
Only
nine amino acids obtained Difficult elimination of toxins in the cultivation broth |
Inexpensive
amino acids for animal feed Not suitable for agriculture or medicine |
| Chemical Synthesis | 1850 (A. Strecker 1956) | Chemical
Reactions. Bonding of elements |
Diverse chemical compounds | Pure amino acids not biologically active in small quantities, very expensive | Use
for chromatography reference High cost precludes other uses |
| Biologically Engineered | 1982 INAGROSA process |
Cellular
bio-synthetic routes Solid state chemistry HPLC chromatography |
Piruvates. Similar to those used in cellular pre-synthesis | All
the fundamental amino acids, pure and
biologically active Oligo peptides similar to Cellular Transcription Factors |
High
purity, biologically active and stable Universal application in medicine, agriculture, cosmetics,etc... Competitive price |
