Abstract
Official abstract text for this publication.
The present invention relates to a process for preparing a yeast hydrolysate comprising less than 100 ppm gluten and at least 1 ppm gluten based on salt-free yeast dry matter.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for preparing a yeast hydrolysate wherein the process comprises the step of contacting a gluten-containing yeast hydrolysate with a proline-specific endoprotease resulting in a yeast hydrolysate comprising less than 100 ppm gluten and at least 1 ppm gluten based on salt-free yeast dry matter. 2. The process according to claim 1 wherein the resulting yeast hydrolysate comprises less than 50 ppm gluten based on salt-free yeast dry matter. 3. The process according to claim 1 wherein the proline-specific endoprotease is classified as EC 3.4.21.26. 4. The process according to claim 1 wherein the proline-specific endoprotease is of a mammalian or a plant or a microbial, origin. 5. The process according to claim 1 wherein the proline-specific endoprotease is a fungal proline-specific endoprotease from a Penicillium species or from an Aspergillus species. 6. The process according to claim 1 wherein the proline-specific endoprotease is from Aspergillus niger. 7. The process according to claim 1 wherein the yeast hydrolysate is a yeast extract or yeast autolysate. 8. The process according to claim 1 wherein the yeast hydrolysate is a spent brewer's yeast hydrolysate. 9. The process according to claim 1 , wherein the yeast is a species from the genera Saccharomyces, Brettanomyces, Kluyveromyces, Candida or Torula. 10. The process of claim 9 , wherein the yeast is a species from the genus Saccharomyces. 11. The process according to claim 1 wherein the resulting yeast hydrolysate comprises less than 40 ppm based on salt-free yeast dry matter. 12. The process according to claim 1 wherein the resulting yeast hydrolysate comprises less than 30 ppm based on salt-free yeast dry matter. 13. The process according to claim 1 wherein the resulting yeast hydrolysate comprises less than 20 ppm gluten based on salt-free yeast dry matter.
