Natural ink production and printability studies for smart food packaging
Abstract
Versatile smart packages provide information on the freshness of the content and help protect the content from microorganisms. In this sense, in this study both natural antimicrobial properties and pH sensitive natural dyes were obtained from red beet. Inks were prepared and printed using this dye and their suitability for smart packaging was investigated. For this purpose, red beet was cut into small sizes and mixed separately in ethanol and water (1:2) at 200 rpm. The betaine dye was taken up in solvent. These solvents were removed with evaporator and precipitated with centrifugation and dried in a vacuum oven. The chemical structure of the obtained dye was illuminated by Attenuated Total Reflection‐Fourier Transform Infrared Spectroscopy (ATR‐FTIR). The color character was determined by UV spectroscopy. Pink colored natural ink was produced by using ink varnish with carboxymethyl cellulose polymer and solid dye. Screen printing was made with this ink and the color, gloss, and lightfastness characters of prints were examined. Antimicrobial effects of the obtained prints were measured against Staphylococcus aureus and Escherichia coli. Mordanting studies were performed with (KAl[SO4]2.12H2O) and change in color character was measured. The prints produced using the red beet extract have a yellow‐orange color in the basic state; in acid cases it was determined to have a pink‐purple color. In addition, it has been found that the ink prints obtained from red beet have antimicrob…

Potassium aluminum sulfate included in red cabbage ink enhances intensity and stability of violet color by forming complexes with anthocyanin pigments.
“Potassium aluminum sulfate was included in the red cabbage (S2) ink to enhance the intensity and stability of the violet color, as it can form complexes with the anthocyanin pigments [23,24].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
