Polyphenolic profile, processing impact, and bioaccessibility of apple fermented products

Area of Science:

• Food Science
• Nutritional Science
• Biochemistry

Background:

• Apples are globally popular, affordable, nutritious fruits suitable for processing.
• Fermentation is a common, cost-effective method for preserving apples and derived products.
• Fermented apple products may offer enhanced nutrient bioavailability and health-promoting compounds.

Purpose of the Study:

• To review the impact of fermentation on the polyphenolic profile of apples.
• To assess the bioaccessibility of polyphenols in fermented apple products.
• To understand how processing and digestion affect apple polyphenol content and health benefits.

Main Methods:

• Literature review of studies on apple fermentation and polyphenol analysis.
• Analysis of polyphenol profiles using in vitro and in vivo digestion models.
• Assessment of processing impacts on polyphenol composition and bioaccessibility.

Main Results:

• Fermentation significantly alters the polyphenolic profile of apples and their products.
• Bioaccessibility of polyphenols in fermented apples varies depending on processing and digestion.
• In vitro digestion methods provide a cost-effective way to study polyphenol changes.

Conclusions:

• Fermentation can enhance the health-promoting properties of apples by modifying polyphenol content and bioavailability.
• Understanding polyphenol changes during fermentation and digestion is key to optimizing health benefits.
• Further research is needed to fully elucidate the health impacts of various fermented apple products.
