Updated 01-2008

  • Quantifying the effects of aging of rice on millability, kernel hardness, and fissure kinetics.
  • Quantifying the effects of drying and tempering treatments on functional, end-use properties of rice
  • Developing NIR-based calibrations for functionality/properties of milled rice.
  • Determining the location of bran/lipids in and on rice kernels milled to various degrees; additionally, determining the location of lipids removed during a Soxtec extraction
  • Comparing NIR color and SLC calibrations developed from lab-milled rice to results of GIPSA assessments.
  • Evaluating the effects of nighttime air temperatures during the R5-R9 growth stages on milling and functional quality using database project data
  • Using kernel breaking force distributions and Perten SKCS 4100 measurements as a means of rapidly predicting HRYs.
  • Quantifying drying rates of rice dried with high temperature air.
  • Quantifying the maximum MC reduction per drying pass, and required tempering durations, to maintain milling quality when drying with high temperature air.
  • Measuring equilibrium moisture contents (EMCs) associated with the above drying treatments and comparing these to values obtained by Jun.
  • Measuring fissure occurrence kinetics in milled rice exposed to a wide range of environments, but concentrating on low temperature conditions.
  • Measuring EMCs of rough, brown, and milled rice, as well as cereal processing products, exposed to a wide range of environments.
  • Relating steady-state fissured kernel percentages to the delta MC between initial rice MC and the EMC associated with the surrounding air.
  • Quantifying the effect of degree of milling (DOM) on milled rice fissure kinetics.
  • Measuring drying rates and resultant milling quality changes using low temperature/low RH air (to simulate desiccated air).
  • Evaluating the effect of insect activity on milling quality degradation.
  • Evaluating desiccant packets as a drying medium for small rice samples.
  • Comparing functional properties of rice milled in laboratory and commercial mills.
  • Developing an automated means of controlling the DOM of rice milled in laboratory mills.
