Effect of organic biocolourants on lightfastness and mechanical properties of polylactic acid

Coloration Technology, Volume 141, Issue 6, Page 921-931, December 2025.
Abstract Most modern colourants are acquired from petroleum‐based sources or mining, which often causes environmental degradation. Consequently, alternative colouring solutions are sought, such as using biocolourants, which are organic colourants from bio‐based sources.

Chemical profiling and characterisation of anthraquinone‐based polyphenols as biocolourants from Cortinarius semisanguineus

Coloration Technology, Volume 141, Issue 6, Page 855-888, December 2025.
Abstract Anthraquinone dyes are known for their significant colour (brightness of shade in the red, blue and green areas) and light fastness properties compared with other synthetic dyes (such as azo‐based dyes). However, challenging multi‐step synthesis of anthraquinones and limited access to fewer substituents result in insufficient reactivity ...

A systematic review of natural colourants and trend forecasting practices for the textile and fashion industry

Coloration Technology, Volume 141, Issue 6, Page 801-827, December 2025.
Abstract Recent global interest in sustainable practices in the textile and fashion industry has inspired stakeholders to readopt natural colourants. However, integrating these practices raises several questions regarding the latest developments in natural colourant and trend forecasting practices in the textile and fashion industry.

Exploration of the natural dye alizarin for supercritical carbon dioxide dyeing of polyester, polyamide and cellulose acetate fibres

Coloration Technology, Volume 141, Issue 6, Page 889-908, December 2025.
Abstract Conventional textile dyeing utilises large amounts of water and generates significant amounts of wastewater, highlighting the need to utilise more sustainable dyeing methods. Supercritical carbon dioxide (scCO2) dyeing offers a zero‐water, zero‐wastewater alternative with reduced energy requirements and carbon dioxide recyclability. While both

Phytochemical Profile and Evaluation of Antioxidant Activity, Enzyme Inhibition and Cell Viability of Leaves Extracts of Three Tunisian Varieties of Diospyros kaki L.

Food Science &Nutrition, Volume 13, Issue 8, August 2025.
Aqueous leaf extracts of three Diospyros kaki varieties (Triumph, Jiro, Rojo Brillante) showed significant antioxidant activity, enzyme inhibition (AChE & HMGR), and lacked cytotoxicity. LC–MS–QTOF identified 29 phenolic compounds, with Rojo Brillante being the richest.
