Title: Bruce L Dwiggins: Innovator in Starch Saccharification

Introduction

Bruce L Dwiggins is a notable inventor based in Decatur, IL (US). He has made significant contributions to the field of starch processing, particularly through his innovative patent related to raw starch saccharification. His work has implications for various industries, including food and biofuel production.

Latest Patents

Dwiggins holds a patent for a multi-step process designed for solubilizing and saccharifying granular starch slurries containing between 20 and 60% dry solids (d.s.) starch. The process involves an initial step where an enzyme mixture with raw starch hydrolyzing activity is added to the slurry. This mixture is maintained in contact until a substantial portion of the starch is solubilized. The resulting syrup is then separated from the remaining insoluble fraction. In the second step, the insoluble fraction is used to create a second slurry with less than 20% d.s. starch, which is then solubilized with a raw starch hydrolyzing enzyme preparation until at least 95% of the starch is solubilized. The pooled syrup from both steps contains over 20 weight percent saccharides, with at least 95% being glucose.
