How Ethanol Production Technology Impacts DDGS Value in Animal Nutrition

Milan Hruby discusses the following in this presentation: - Phytate is a strong chelator of minerals and interacts with proteins and starch Ion chromatography with suppressed conductivity detection is used to resolve inositol phosphates; Sample preparation exemplifies the troublesome chemical nature of phytic acid; SPEZYME® RSL provides enhanced liquefaction at lower pH’s DISTILLASE® SSF+ provides yeast nutrients and is capable of reducing phytate levels in DDGs below detectable limits; Phytate content in DDGS available to US animal feed industry is variable affecting P availability Almost no phytate P detected in DDGS samples from the ethanol processes, which are using phytase in fermentation DDGS derived from the phytase treatment can have ignificantly higher true metabolizable energy (TME) and digestibility of some amino acids, especially those present at high concentrations in endogenous protein DDGS with reduced phytate content has a superior nutritional value than classic DDGS
