Starch Hydrolysate Production via Sift Grinding and Hydrolysis

The patent converts the harmful effect of excess starch by-product into a beneficial outcome by further processing it through hydrolysis and fermentation. The starch that was previously wasted is transformed into valuable products such as lactic acid, fungal protein mixture, and other marketable compounds, thereby eliminating the loss and creating additional revenue streams.

The patent applies parameter changes by altering the chemical state of starch through hydrolysis (changing starch into fermentable sugars) and then through fermentation (converting sugars into lactic acid and other products). This series of parameter changes transforms the unwanted starch by-product into high-value chemical and biological products.

The patent applies multi-functionality by using the same starch-rich fraction as a substrate for multiple different fermentation processes. The hydrolyzed starch can be simultaneously or sequentially used to produce lactic acid, fungal protein mixture, and other valuable compounds, thereby justifying the additional processing steps through multiple product outputs from a single input stream.

The patent segments the processing into distinct stages: hydrolysis of starch into sugars, followed by separate fermentation pathways for different products. This segmentation allows each process step to be optimized independently and enables flexible production of multiple products from the same starting material, making the complex process more manageable and economically viable.
