FAQ

  • Hydrolysates are proteins digested into smaller fragments, peptides, and its sole building blocks, the amino acids. A hydrolysate is therefore a blend of different peptides and different peptide lengths. In the hydrolysis process, we start with the intact protein, for instance whey or casein, which is digested by enzymes into smaller fragments. The hydrolysis process influences the peptide size. Depending on the level of hydrolysis, we are able to obtain mildly hydrolysed, partially hydrolysed or extensively hydrolysed proteins. Moreover, the peptides can be filtered, in order to obtain a mixture with very small peptides and no larger fragments.
    The degree of hydrolysis is defined as the percentage of the number of peptide bonds in a protein which have been cleaved during hydrolysis. Upon enzymatic hydrolysis of the peptide bonds in a protein, new amino groups are formed, one amino group for each broken peptide bond. The amount of newly formed amino groups causes a linear increase in amino nitrogen. This amino nitrogen can be determined by formol titration. In the calculation of the degree of hydrolysis, the increase of amino nitrogen, corrected for the total number of peptide bonds available for cleavage in the protein is calculated.
    Hydrolysates are hydroscopic and need to be kept dry.  Therefore the optimum storage to prolong their life is tightly sealed, air tight containers or bags. These containers or bags should only be opened when they are ready to be used.

  • Depending on the base medium used for the hydrolysates, the ultrafiltered hydrolysates have a 10 – 20% solubility.  Proyield® Pea PCE80B is the exception having an approximate 5% solubility.
    Standard practice to determine a hydrolysate concentration in a medium formulation, is to titrate the hydrolysate, usually between a  1-8 gm/L concentration.  This titration should be performed using the base medium of choice.
    Selecting a base medium should be performed in concert with selecting your hydrolysate. The chemicals in the base medium can sometimes have a profound effect upon the overall outcome of the cell culture process.

  • Most of these hydrolysates are soluble at 5% solutions, some will be soluble at up to 10%.
    Our range of protein hydrolysates for microbial nutrition can be found here:
    Yes, however consideration is needed regarding the overall nutritional composition of the medium and the purpose of the fermentation. In many cases, it is possible to improve the yield of the medium.
  • We offer protein hydrolysates containing peptide-bonded glutamine. Glutamine is the single most abundant amino acid in the body being conditionally limited upon strenuous conditions like illness. We offer a range of hydrolysates derived from various protein sources to meet the diverse needs of medical nutrition formulators. Please contact us to discuss solutions for your application.
    Hyvital® Wheat Glutamine hydrolysates are derived from natural wheat protein. Using an enzymatic treatment, the large protein molecules are split into small groups of amino acids, called peptides, which contain the amino acid Glutamine. The enzymes used are food grade, there are two variants: Hyvital® Wheat Glutamine GN and Hyvital® Wheat Glutamine PA. The latter is specifically designed for acidic formulations.
    Hyvital Wheat Glutamine contains peptide-bonded glutamine. Numerous clinical investigations have shown that glutamine enriched medical nutrition support decreases hospital-acquired infections and improves other clinical outcomes (hospital length of stay, post-hospital survival) in critically ill patients1-3
    Hyvital® Wheat Glutamine contains Peptide-bonded glutamine, which is a natural source of glutamine in comparison to free glutamine which is a synthetically prepared amino acid. Furthermore, peptide-bonded glutamine comes with application advantages:
    • It is stable in liquid drinks: Glutamine as a free amino acid is unstable, and may even form toxic substances upon heating.
    • It is heat stable. Free Glutamine may undergo ring condensation to form pyroglutamic acid which is suspected to have neurotoxic properties.
