The structural characterization, physicochemical properties, and stability of gardenia yellow pigment microcapsules

Liqin Tang et al.

Summary: GYP microcapsules were successfully prepared using different wall materials, showing good thermal stability and loading capacity. WP-MD microcapsules demonstrated significantly higher encapsulation efficiency and loading amount than other microcapsules, while spray-dried double emulsion microcapsules exhibited lower hygroscopicity. The stability studies revealed all microcapsules could improve the thermal stability, light stability, and pH stability of GYP with no significant difference between them.

Purification and properties of a laccase from the mushroom Agaricus sinodeliciosus

Jingzhe Hao et al.

Summary: A homogeneous monomeric laccase (ASL) with a molecular mass of 65 kDa was isolated from Agaricus sinodeliciosus, showing maximum activity at 50 degrees C and pH 5.0, while being significantly inhibited by Hg2+ and Cd2+. The laccase displayed a K-m value of 0.9 mM toward ABTS and exhibited higher affinity toward o-toluidine and benzidine. ASL is capable of decolorizing malachite green and Eriochrome black T.

The effect of lipid metabolism regulator anthocyanins from Aronia melanocarpa on 3T3-L1 preadipocytes and C57BL/6 mice via activating AMPK signaling and gut microbiota

Chunping Chen et al.

Summary: The study demonstrated that anthocyanins from Aronia melanocarpa (AAM) regulate lipid metabolism by decreasing lipid content and inflammation, improving blood lipid levels, promoting beneficial gut microbial growth, and maintaining lipid metabolism. AAM achieves this through activating the AMP-activated protein kinase (AMPK) signaling pathway and regulating adipogenic transcription factors and genes associated with fat metabolism. The findings suggest that AAM has potential therapeutic effects on hyperlipidemia.
