Biovalorization of spent Konacha tea leaves via single-culture fermentation involving wine yeasts and lactic acid bacteria.

Aims: The objective of this study was to explore the potential of fermentation as a biovalorization strategy for spent tea leaves (STL), a major agrifood waste generated from the tea extraction industry. Fermentation by wine yeasts or lactic acid bacteria (LAB) has shown promising results in previous studies across various substrates.

Methods And Results: Konacha (green tea) STL slurries were inoculated with single strains of wine yeasts or LAB respectively.

Recent advances in analytical strategies for coffee volatile studies: Opportunities and challenges.

Coffee has attracted significant research interest owing to its complex volatile composition and aroma, which imparts a pleasant sensorial experience that remains challenging to analyse and interpret. This review summarises analytical challenges associated with coffee's volatile and matrix complexity, and recent developments in instrumental techniques to resolve them. The benefits of state-of-the-art analytical techniques applied to coffee volatile analysis from experimental design to sample preparation, separation, detection, and data analysis are evaluated.

Ingredients, Processing, and Fermentation: Addressing the Organoleptic Boundaries of Plant-Based Dairy Analogues.

Consumer interest and research in plant-based dairy analogues has been growing in recent years because of increasingly negative implications of animal-derived products on human health, animal wellbeing, and the environment. However, plant-based dairy analogues face many challenges in mimicking the organoleptic properties of dairy products due to their undesirable off-flavours and textures. This article thus reviews fermentation as a viable pathway to developing clean-label plant-based dairy analogues with satisfactory consumer acceptability.

Effect of solid-state fungal fermentation on the non-volatiles content and volatiles composition of Coffea canephora (Robusta) coffee beans.

In this study, the effects of fungal fermentation on green canephora coffee beans were evaluated by observing the changes to selected non-volatile parameters before roasting, and subsequently the volatile profile after roasting. Solid-state fermentation (SSF) by Aspergillus spp. and Mucor spp.
