“…Finally, agar plates were incubated at 35 °C with different times, and the number of colonies was recorded. The bacterial counts were expressed as colony-forming units (CFU) per gram of beef, and then transformed to base 10 logarithm values, namely log 10 (CFU/g) or lg(CFU/g) [ 21 ].…”

A ratiometric fluorescent sensor with hydrogen sulfide (H2S) and methanthiol (CH3SH) sensitivity was developed to real-time monitor beef freshness. A silicon quantum dots (SiQD) and silver nanoclusters (AgNC) complex, namely SiQD-AgNC, was used as the dual emission fluorescence materials. Due to the fluorescence resonance energy transfer (FRET) effect between SiQD and AgNC, when the fluorescence of AgNC (610 nm) was quenched by H2S or CH3SH, the fluorescence of SiQD (468 nm) recovered, resulting in an increase of the fluorescent intensity ratio (I468/I610). I468/I610 showed a linear relationship with the H2S concentration within the concentration range of 1.125–17 μM, with a limit of detection (LOD) value of 53.6 nM. Meanwhile, I468/I610 presented two linear relationships with the CH3SH concentration within the concentration range of 1.125–17 μM and 23.375–38.25 μM, respectively, with a LOD value of 56.5 nM. The SiQD-AgNC complex was coated on a polyvinylidene fluoride (PVDF) film to form a portable SiQD-AgNC/PVDF film sensor. This film showed purplish red-to-cyan color changes in response to H2S and CH3SH, with LOD values of 224 nM and 233 nM to H2S and CH3SH, respectively. When the film was used to monitor beef freshness at 4 °C, its fluorescent color gradually changed from purplish red to cyan. Hence, this study presented a new ratiometric fluorescent sensor for intelligent food packaging.

“…This protonation-deprotonation process is highly reversible under cooling-heating conditions. Four isomeric forms of anthocyanidin were detected upon heating, including quinoid anion, carbinol anion, chalcone, and flavylium cation [31,32]. At high temperatures, the flavylium positive ion (red) is the dominant isomeric form.…”

“…A similar trend of diminishing hydroxyl group intensity was seen when the mordant-anthocyanin nanoparticles concentration was raised. Intramolecular charge transfer on the molecular structure of anthocyanin can be triggered by heat, leading to the formation of the corresponding highly extended molecular form [30][31][32][33]. Figure 4 shows the thermochromic properties of a paper sheet printed with the mordant-anthocyanin complex nanoparticles.…”

“…In comparison to other organic molecular probes, anthocyanins are highly reversible, biodegradable, biocompatible, inexpensive, and stable. Thus, it is suggested that anthocyanin-based spectroscopic active sites are a great option for delivering thermochromic anti-counterfeiting to paper documents without affecting the paper key attributes, including mechanical behavior and appearance [32,33].…”

Preparation of novel authentication film by screen printing of anthocyanin biomolecular extract: Thermochromism and vapochromism

et al. 2023

Novel thermochromic and vapochromic paper substrates were prepared via screen printing with anthocyanin extract in the presence of ferrous sulfate mordant, resulting in multi‐stimuli responsive colorimetric paper sheets. Environmentally friendly anthocyanin extract was obtained from red‐cabbage (Brassica oleracea var. capitata L.) to function as spectroscopic probe in coordination with ferrous sulfate mordant. Pink anthocyanin/resin nanocomposite films immobilized onto paper surface were developed by well‐dispersion of anthocyanin extract as a colorimetric probe in a binding agent without agglomeration. As demonstrated by CIE colorimetric studies, the pink (λmax = 418 nm) film deposited onto paper surface turns greenish‐yellow (λmax = 552 nm) upon heating from 25 to 75°C, demonstrating new thermochromic film for anti‐counterfeiting applications. The thermochromic effects were investigated at different concentrations of the anthocyanin extract. Upon exposure to ammonia gas, the color of the anthocyanin‐printed sheets changes rapidly from pink to greenish‐yellow, and then immediately returns to pink after taking the gaseous ammonia stimulus away, demonstrating vapochromic effect. The current sensor strip showed a detection limit for ammonia gas in the range 50–300 ppm. Both thermochromism and vapochromism showed high reversibility without fatigue. In addition to studying the rheological properties of the prepared composites, the morphological and mechanical properties of the printed cellulose substrates were also studied.

“…The bigels’ mixing procedure is commonly achieved by mixing two hot phases at temperatures higher than 70 °C (ref. 23, 32 and 34–37) or two cold, gelled phases. 15,21,27,38 The effect of the homogenization or mixing temperature on a bigels’ characteristic has not been explored to date.…”
