Improve on the economics to obtain modified pectins and other high value products from citrus waste streams through modifications which incorporate extraction of pectin or a modified pectin fraction as part of an integrated process to recover limonene and produce ethanol from the fermentable sugars and cellulose contained in citrus processing or other agricultural waste. The developed technology will be based on enzymatic and/or chemical modifications to pectin and other polysaccharides to incorporate and characterize novel functionality, and then target utilization in non-food applications such as ion exchange materials, suspension aids, viscosity enhancers, metal chelation, and water retention agents. Development of the new products based on citrus or other agricultural polysaccharides will emphasize use of green applications with cost effective extraction processes or uses which allow use of crude fractions requiring minimal extraction.
