Bioavailability Enhancement: Drug Stability Enhancement and GI Retention

Bioavailability Enhancement: Drug Stability Enhancement and GI Retention

Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...

Production of Organic Acids

Production of Organic Acids

Lactic acid, an important organic acid extensively applied in food, pharmaceutical, and biodegradable polymer industries, is primarily produced via microbial fermentation. This method is favored over chemical synthesis due to its environmental sustainability and capacity for enantiomerically pure product formation. Among various microbial processes, the fermentation of starch-based substrates stands out due to the abundance and renewability of raw materials like corn and potatoes.Hydrolysis of...

To focus on environmentally sustainable, non-thermal physical modification methods.
To explore how these modifications enhance PS functionality for next-generation food ingredients.

Main Methods:

Consolidation of recent research on porous starch modification techniques.
Emphasis on non-thermal physical methods, applied individually or in combination.
Analysis of how these methods alter starch structure and properties.

Main Results:

Sustainable modification techniques improve porous starch's functional attributes.
Enhanced PS exhibits improved stability and performance in food applications.
Novel properties are created, expanding potential uses in food products.

Conclusions:

Environmentally friendly modification of porous starch is crucial for sustainable food processing.
Advanced porous starches offer enhanced functionality for innovative food product development.
These findings support the creation of cleaner and greener food technologies.
