Abstract
- Enzymatic browning and microbial growth are two natural phenomena that occur when fruits and vegetables are exposed to abnormal conditions, i.e., temperatures in the range of 12–22 °C, leading to their spoilage. Controlling the temperatures during the supply chain aims to optimize the product's shelf life. Irreversible thermochromic beads were fabricated using a simple extrusion technique containing fatty acid, lecithin, and anthocyanin solution-alginate. The pigmentation durability was adjusted based on electrostatic interactions, as evidenced by the reduction in dye leaching in the case of the produced bead at pH = 6 to less than 0.007 after 45 min. Characterization shows that the chosen combination of fatty acids and the quinonoid molecule is useful for producing thermochromic beads, with a color change at 12 °C–22 °C, from blue to purple. Using the prepared thermochromic beads in the supply chain of fresh-cut salad and brussels sprouts showed a great result for monitoring their freshness after 21 ± 1 min. • Simple extrusion-based preparation of irreversible thermochromic sensors for smart packaging. • Thermosensor based on edible molecules from red cabbage, oils, and eggs. • Pigmentation was stabilized via electrostatic interaction between core-shell structure in beads. • Thermochromic beads change the color above 12 °C. • The possible color change mechanism and application in packaging were clarified [ABSTRACT FROM AUTHOR]
