Delivering hydrophobic bioactive compounds remains a challenge, particularly in co-delivery of multiple immiscible compounds. Limited research has explored co-encapsulating hydrophobic actives using macromolecules. In this study, ellagic acid as a solid hydrophobic substance and Litsea Cubeba essential oil as an oily hydrophobic component were successfully loaded using heat- and ultrasonic- treated soy protein as a carrier.

The study investigated the perceptual interaction between two types of Rose damascena essential oil and two types of Angelica dahurica root essential oil. Using gas chromatography-olfactometer (GC-O) and gas chromatography-mass spectrometer (GC-MS), 24 and 25 aromatic compounds in Rose damascena essential oil and Angelica dahurica root essential oil were identified and quantified, respectively. Based on flavor dilution (FD) values and odor activity values (OAVs), 10 important aroma compounds in Rose damascena essential oil and 6 in Angelica dahurica root essential oil were identified.

Lavender (Lavandula angustifolia Mill.) is a widely utilized aromatic plant, with the economic value of its essential oil (EO) largely dependent on its aroma. This study investigated the differences in volatile organic compounds (VOCs) within the EOs of three species of lavender (H70-1, French blue, Taikong blue) in Ili region from 2019 to 2023 with the combination of sensory evaluation, gas chromatography-ion mobility spectrometry (GC-IMS), and gas chromatography-mass spectrometry (GC-MS).

Alzheimer's disease (AD) is a neurodegenerative disorder that is projected by the WHO to affect over 100 million people by 2050. Clinically, AD patients undergoing long-term antipsychotic treatment often experience severe anxiety or depression in later stages. Furthermore, early-stage AD manifests with weakened α waves in the brain, progressing to diminished α and β waves in late-stage disease, reflecting changes in emotional states and disease progression.

Article Synopsis
  • The study focuses on improving the solubility and stability of ellagic acid (EA), a beneficial phytochemical with antioxidant properties, by encapsulating it in soy protein isolate (SPI) using a pH-shift method.
  • Results showed that the interaction between SPI and EA is favorable, with EA molecules significantly quenching the fluorescence of SPI, and successful encapsulation confirmed via various analytical techniques.
  • The SPI-EA complex demonstrated high encapsulation efficiency, significant radical scavenging ability, and improved resistance to degradation under harsh conditions, enhancing its potential application in the food industry.

The aroma of mint is well-liked by the public, and key flavor odorants in mint aroma had been found, but how these molecules interact and form a satisfying odor remains a challenge. Quality, intensity, and pleasantness are our most basic perceptions of aromas; both intensity and pleasantness can be quantified. However, compared to intensity, research on pleasantness was lacking.

This study investigated a novel antioxidant and antimicrobial Pickering emulsion stabilized by soy protein isolate (SPI) and gallic acid (GA) as an excellent protective delivery medium for lipophilic functional food. SPI-GA complex nanoparticles were fabricated by a covalent cross-linking mechanism under alkaline conditions with a small particle size (42.93-24.

A facile transition-metal-free protocol to form 2-iminoimidazo[1, 2-]-pyridines bearing a -CHBr group and an aza-quaternary carbon center at the 3 position from -(2-pyridyl)amidines substrates, in which the new heterocyclic skeletons constructed from amidines radical reactions or nucleophilic substitution reactions are promoted only by CBr under mild conditions, is demonstrated. The reactions were realized by intramolecular CDC reaction involving C-N and C-C bond formation the sequential C(sp)-H bifunctionalization mode on the same carbon atom under mild conditions. Moreover, this work also provides an excellent and representative example for CBr as an efficient reagent to initiate radical reactions under initiator-free conditions or to give rise to nucleophilic substitution reactions only by base.
