Unraveling the color evolution and metabolic pathways of pelargonidin-3-O-glucoside during lactic acid fermentation of the strawberry juice color simulation system: A novel perspective through untargeted metabolomics.

This study aimed to unraveling the color evolution and metabolic pathways of pelargonidin-3-O-glucoside (P3G) during lactic acid fermentation of the strawberry juice color simulation system. The results revealed that fermentation with both Lactobacillus plantarum and Lactobacillus acidophilus caused a decline in pH of the strawberry juice color simulation system and significantly accelerated the decrease in P3G content. The CIELAB space model pointed out that parameters a and b of the group treated with both lactic acid bacteria and P3G initially increased to a peak level and then gradually decreased, shifting the overall color towards orange and then gradually fading.

Fabrication and characterization of anthocyanin-loaded double Pickering emulsions stabilized by β-cyclodextrin.

Anthocyanins, one of the important water-soluble pigments, are sensitive to environmental factors, which limits the application of anthocyanins in food field. In order to overcome this limitation, double Pickering emulsions stabilized by β-cyclodextrin were developed. The optimum preparation conditions of the emulsions were determined firstly and the performance and structure of emulsions were investigated.

Wideband 1-bit reconfigurable transmission metasurface unit cell design in Ka-band with polarization hold and conversion.

In this paper, a wideband transmission unit cell is proposed for programmable metasurfaces operating in the Ka-band. The unit cell features a compact period of only 2.91 mm, corresponding to 0.
