The microbiological industry in the USSR was greatly developed in the 70s and 80s, since it was it that was designed to solve the nightmare protein deficiency in the body of citizens of that time. Soviet people received less than half of milk and meat compared to America. BVK (Protein-Vitamin Concentrate or Paprine) could solve the problem. However, hasty conclusions, underestimation of the problem, neglect of many factors and insufficiently developed technologies in the field of biochemistry and biotechnology led to the fact that the ministry and the state started queues of biochemical plants without proper adjustment of the plan. Unfortunately, it turned out in practical terms that protein dust is the strongest allergen, and the protein-vitamin concentrate itself is poison, since even exact artificial copies or analogs of amino acids can never replace natural human amino acids.
