Medicinal plants fermentation: current knowledge and perspectives

Area of Science:

• Food Science
• Biotechnology
• Phytochemistry

Background:

• Medicinal plants contain valuable bioactive compounds often limited by poor bioavailability, toxins, and undesirable sensory attributes.
• Fermentation offers a transformative approach to overcome these limitations in plant-based materials.

Purpose of the Study:

• To explore how fermentation enhances the value of medicinal plants for functional foods, nutraceuticals, and phytomedicine.
• To detail the mechanisms by which fermentation improves bioactivity, safety, and sensory profiles of plant matrices.

Main Methods:

• Review of recent studies on microbial biotransformation of plant materials like moringa, noni, and chaga.
• Analysis of fermentation-induced changes including phytochemical release, metabolite production, detoxification, and sensory modification.

Main Results:

• Fermentation significantly enhances plant value by modulating bioactivity, detoxifying compounds, and optimizing taste and aroma.
• Microbial action releases bound phytochemicals, transforms polyphenols, generates novel metabolites, and reduces anti-nutritional factors.

Conclusions:

• Fermentation presents a powerful strategy for developing advanced functional products with superior bioactivity, safety, and sensory appeal.
• Future research should focus on standardization, mechanistic studies using multi-omics, and regulatory considerations for wider application.
