Powdered hibiscus anthocyanin‐nanofibril complexes as natural colourants: Stability and application in yoghurt and soft candy

Coloration Technology, EarlyView.
Abstract The instability of anthocyanins limits their application as natural food colorants. This study aimed to enhance the stability of anthocyanins extracted from Hibiscus sabdariffa through copigmentation with protein nanofibrils produced from pea, rice, gluten and whey isolates. Linear and curly nanofibril structures were prepared and incorporated

Meeting the New (Old) Ecological Challenges for Art Education

International Journal of Art &Design Education, EarlyView.
Abstract The discussion examines the emerging ecological critique of art education, which frames artistic production, especially in the plastic arts, as environmentally unsustainable due to its reliance on non‐essential material consumption. I argue that this critique, while contemporary in form, echoes long‐standing philosophical concerns, beginning ...

The Cost of Convenience: A Hedonic Approach to Travel Time Valuation and Cost‐Benefit Analysis

Journal of Regional Science, EarlyView.
ABSTRACT This paper presents a novel revealed‐preference approach to estimating the value of travel time (VTT) and calculating consumer surplus for the economic evaluation of transport infrastructure. Departing from traditional stated‐preference models, we derive time valuations by linking residential rental transactions in Greater Sydney to employment

The Role of Hibiscus sabdariffa L. (Roselle) in Maintenance of Ex Vivo Murine Bone Marrow-Derived Hematopoietic Stem Cells

The Scientific World Journal, 2014
Hematopoietic stem cells- (HSCs-) based therapy requires ex vivo expansion of HSCs prior to therapeutic use. However, ex vivo culture was reported to promote excessive production of reactive oxygen species (ROS), exposing HSCs to oxidative damage ...

Using Local Expert Knowledge to Measure Prices: Evidence From a Survey Experiment in Vietnam

Review of Development Economics, EarlyView.
ABSTRACT Many countries lack spatially disaggregated consumer price data needed to estimate real inequality and spatial patterns of poverty. Such data are especially absent in poor countries where weak infrastructure and high transport costs create large price variation over space.

Validation of ShakeMaps Created From Global Navigation Satellite System (GNSS) Velocities

Earthquake Spectra, Volume 42, Issue 3, August 2026.
Ground velocity observations generated through a time difference of Global Navigation Satellite Systems (GNSS) phase observables and orbits have been shown to be comparable to seismic recordings without clipping during intense ground motions. Computing GNSS velocities is also computationally scalable and increases the density of ground motion ...

Comprehensive Phytochemical Profiling and Multi‐Target Biological Evaluation of Hibiscus sabdariffa L. Calyx Extracts From Libya: A Promising Functional Food Candidate With Antibacterial, Antioxidant, Anti‐Inflammatory, and Cytotoxic Properties: Validation Through In Silico Approaches

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
This study presents a comprehensive evaluation of Hibiscus sabdariffa L. calyx extracts from Libya, integrating phytochemical profiling, multi‐target biological activities, and in silico validation. Aqueous and ethanolic extracts were prepared and assessed for antibacterial activity against multidrug‐resistant clinical isolates (MIC: 6.25–25 mg/mL; MBC/

Ulva lactuca Extract in Confectionery Systems: A Sustainable Approach to Natural Pigmentation, Antioxidant Enrichment, and Sensory Optimization in Fondant and Meringue Matrices

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
This study evaluated the functional potential of Ulva lactuca extract as a natural colorant and antioxidant incorporated into sugar‐based (fondant) and aerated (meringue) confectionery matrices. Extract incorporation significantly enriched total phenolic content—achieving up to 150.95 mg GAE/100 g dry matter in meringues—and surged antioxidant ...
