Phycocyanin - Wikipedia
Phycocyanin is a characteristic light blue color, absorbing orange and red light, particularly 620 nm (depending on which specific type it is), and emits fluorescence at about 650 nm (also depending on which type it is).
Physicochemical degradation of phycocyanin and means to …
Jun 1, 2022 · The optimal working pH range for phycocyanin is between 5.5 and 6.0 and it remains stable up to 45 °C; however, exposure to relatively high temperatures or acidic pH decreases its half-life and increases the degradation kinetic constant.
A review of recent strategies to improve the physical stability of ...
Phycocyanin is found to be unstable at the pH values between 4.0 and 4.8, which is fairly close to its isoelectric point (pH 3.4) (Li et al., 2021). Some researchers reported that phycocyanin was insoluble under acidic conditions (pH 3.0) but highly soluble under neutral conditions (pH 7.0) ( Antelo et al., 2008 ).
Phycocyanin from Spirulina: A comprehensive review on …
May 1, 2024 · Phycocyanin is a blue accessory protein pigment that is abundant in Spirulina sp. and has gained popularity due to its diverse applications in various industries. Phycocyanin is rich in natural properties that can be used as a nutraceutical, …
Phycocyanin - an overview | ScienceDirect Topics
Phycocyanin is a pigment-protein complex that biologically functions cooperatively with chlorophyll in photosynthesis. Specifically, phycocyanin increases the efficiency of chlorophyll's oxygen production under low light conditions. Phycocyanins are blue in color which results from their absorption of red-orange wavelengths of light.
Potential protein phycocyanin: an overview on its properties ...
Oct 31, 2023 · A crucial pigment protein from its photosynthetic machinery called phycocyanin has been extensively studied for its immense application in fluorescent probe, food additives, nutraceutical applications, and silver-nanoparticles production.
Spectral and conformational characteristics of phycocyanin …
Jan 15, 2024 · Phycocyanin, a photosynthetic pigment from the phycobiliprotein family, is the main component of water-soluble light-harvesting complexes (phycobilisomes, PBS). The PBS unit consists of a core made of the protein allophycocyanin, surrounded by several perpendicularly oriented rods with stacked disks of phycocyanin and sometimes, other proteins.
Exploring the Benefits of Phycocyanin: From Spirulina ... - MDPI
Apr 14, 2023 · According to major studies, phycocyanin is best preserved when the temperature is below 45 °C, the pH is between 5.5 and 6.0, storage is in the dark, and preservatives such as mono- and di-saccharides, citric acid, crosslinkers, and natural polymers are used.
Stability and Antioxidant Activity of Food-Grade Phycocyanin …
Jun 27, 2016 · Between 60 and 65ºC, the phycocyanin solution at pH 6.0 was most stable, but at 70 and 75ºC it was most stable at pH 5.0, as evidenced by the increased C R values. This result is consistent with those for the 30 min treatment previously described.
Phycocyanin content and nutritional profile of
Apr 5, 2021 · We found that the most appropriate pH was 7, at − 20 °C. Potassium hydroxide was added to raise the pH of the phycocyanin solution to 7 from an initial pH of 6.4. The highest amount of C-PC was 89.5% at 4 °C up to 21 days.
