Abstract:
The use of ozonation has been discovered to increase the lutein extraction from aflatoxin-free corn and for some batches of alfalfa. In addition, the ozonation will substantially decrease any aflatoxin in the plant source. The structure of lutein as indicated by HPLC elution profile and the function of lutein using an antimutagenic activity was shown not to be affected by the ozonation.


Description:
An insoluble resistant starch product produced from a native ungelatinized, unhydrolyzed insoluble starch, wherein said product exhibits a pasting temperature and a peak viscosity that are within 25% of that exhibited by the native starch, wherein said product contains a higher percentage of starch molecules that are resistant to alpha-amylase digestion as compared to the native starch, wherein said product displays a resistant starch temperature peak from about 116° C. to about 125° C. in a heating profile as measured by differential scanning calorimetry, wherein said product has from about three-fold to about twelve-fold increase in the percentage of starch molecules that are resistant to alpha-amylase digestion as compared to the native starch.
