Gelatin based nanoparticles was prepared by sodium trimetaphosphate (STMP) for stabilizing and fabricating high internal phase emulsions (HIPEs), and cyanophycin and capsanthin were single/dual-encapsulated in emulsion systems. The characterization of FTIR, XRD, TGA, zeta potential, particle sizes, dilatation rheology and AFM indicated that the phosphate groups of STMP could react with side chain groups of gelatin and chitosan to form nanoparticles, and enhance the thermal resistance. The nanoparticles could form strong membrane on the oil-water interface, which prevents stratification and precipitation of HIPEs, and promotes high centrifugation stability and freezing-thawing stability. The functional HIPEs with single encapsulation of medium-content cyanophycin or capsanthin have excellent colors, shear thinning performance, structure reversibility, mechanical strength, elasticity and strong network systems with small emulsion droplets; however, the mixed purple HIPEs illustrated the relative weak network structure and the low final strain recovery rates with the enlarged emulsion droplets. On another hand, the simultaneous load of cyanophycin and capsanthin in emulsion systems could produce bright purple HIPEs based on Subtractive Color Principle, and HIPEs possess the outstanding rheological characteristics and the structured systems with small emulsion droplets. The outstanding extrudability and excellent combinational 3D printability of functional HIPEs suggest the great potential in personalized, innovative food production.

The current photoinitiator (PI) is effective under mercury lamps but exhibits limited selectivity towards different radiation sources, which hinders its compatibility with eco-friendly LED lighting and raises concerns about toxicity and deep coloration. Capsanthin (Cap), with its strong photo-absorption in the 400–500 nm range, utilizes its conjugated structure to align the PI's absorption wavelength with the LED's emission spectrum . This study introduced Cap as a natural photosensitizer (PS) for free radical photopolymerization under LED irradiation. The Cap-based initiation system demonstrated promising photoinitiating capabilities under a 405 nm LED , achieving over 50 % double bond conversion in polymerized monomers . Furthermore, the system's photobleaching properties were exceptional, and its cytotoxicity was significantly lower than that of traditional PIs, such as benzoin methyl ether. The Cap's photochemical behavior under LED irradiation was explored, investigating its photoinitiating capacity and mechanism through fluorescence, photolysis, and electron paramagnetic resonance techniques. This research is vital for developing bio-based photoinitiating systems for photopolymerization in LED light environments.

This work presented a facile way of stabilizing capsanthin by physically-connected soft hydrogels via utilizing specially-structured polysaccharides , and investigated rheological properties, self-recovering mechanism and 3D printability. The functionalized hydrogels demonstrated excellent color quality including redness, yellowness index and hue with great storage stability and visual perception. The soft hydrogels fabricated with properly sequenced polyglyceryl fatty acid esters , β-cyclodextrin, chitosan, and low-content capsanthin possessed outstanding extrudability, appropriate yield stress, reasonable mechanical strength, rational elasticity and structure sustainability. Furthermore, the self-recovering properties based on hydrogen bonds , host-guest interactions and electrostatic interactions were revealed and verified by structural, zeta potential , micro-morphological, zeta potential, thixotropic, creep-recovery, and macroscopic/microscopic characterizations. Along with excellent antioxidant performance, the subsequent 3D printing onto bread with complex models elucidated the high geometry accuracy and great sensory characters. The sequenced physically-connected hydrogels incorporated with capsanthin can provide new insights on stabilizing hydrophobic biomaterials and developing the 3D printed exquisite, innovative food .

2,5-Dimercapto-1,3,4-thiadiazole (DMTD) was used as a cross-linking agent and photoinitiator in conjunction with capsanthin and iodonium salt to construct a photoinitiating system suitable for UV-LED irradiation. In a fully green synthesis method, this photoinitiating system enables the thiol-epoxy polymerization and thiol-ene polymerization of biobased monomers, such as epoxidized soybean oil and eugenol, with final conversion rates exceeding 70%. The structure of the prepared coating becomes denser with increasing DMTD content, leading to improved hydrophobicity, wear resistance, thermal stability, and hardness. At the optimal DMTD content of 20 wt %, the coating EP20 exhibited an adhesion level of 0, an Aspergillus niger (A. niger) infection value of 1, and a water contact angle of 109.7°. The addition of eugenol further enhanced the coating’s antifungal properties, reducing the A. niger infection value to 0. This approach provides significant guidance for achieving sustainable development through “sustainable (biobased prepolymers) + eco-friendly (bioinitiating systems) + green (environmentally friendly curing processes)”.

Here we use natural Chinese paprika to prepare a new kind of amphiphilic carbon dot (A-Dot) that exhibits bright, multicolored fluorescence and contains hydrophilic groups as well as lipophilic capsanthin tails on the surface. It is found that the capsanthin tails in a phospholipid-like structure can promote cell internalization of the A-Dots via crossing cell membranes rapidly in an energy-independent fashion. Compared to highly hydrophilic carbon dots (H-Dots), a control sample prepared from the microwave thermolysis of citric acid and ethylenediamine, our synthesized A-Dots can be taken up by CHO, HeLa, and HFF cells more easily. More importantly, we develop a method to calibrate the hydrophilic–lipophilic balance (HLB) values of various kinds of carbon dots (C-Dots). HLB values of A-Dots and H-Dots are determined to be 6.4 and 18.4, respectively. Moreover, we discover that the cellular uptake efficiency of C-Dots is closely related to their HLBs, and the C-Dots with an HLB value of around 6.4 cross the cell membrane easier and faster. As we regulate the HLB value of the A-Dots from 6.4 to 15.3 by removing the capsanthin tails from their surfaces via alkali refluxing, it is found that the refluxed A-Dots can hardly cross HeLa cell membranes. Our work is an essential step toward understanding the importance of regulating the HLB values as well as the surface polarity of the C-Dots for their practical use in bioimaging and also provides a simple but effective way to judge whether the C-Dots in hand are appropriate for cell imaging.
