A novel colorimetric indicator based on agar incorporated with Arnebia euchroma root extracts for monitoring fish freshness
Abstract
Abstract This work aimed to develop and characterize a novel indicator film for monitoring fish freshness based on agar incorporated with natural dye extracted from Arnebia euchroma root (AEREs). The Fourier transform infrared spectroscopy results reflected that some new interactions have occurred between polymer matrix and natural dye. And the results of X-ray diffraction and scanning electron microscopy indicated that AEREs were well dispersed in the agar base film. A certain decrease was observed in water solubility, swelling ratio and elongation at break of colorimetric film but tensile strength, Young's modulus, water vapor permeability and water contact angle of colorimetric film were increased by addition of AEREs. The prepared indicator films were used as freshness labels in an application trial, which was conducted to monitor the freshness of Wuchang bream (Megalobrama amblycephala) under refrigeration (4 °C) and at room temperature (25 °C). The total volatile basic nitrogen (TVB-N) and total viable count (TVC) of fish sample were determined periodically, and the color change of freshness labels was recorded simultaneously. The results showed that the indicator film with lower content of AEREs demonstrated more conspicuous color change during fish spoilage. And the color response of freshness label was consistent with the spoilage threshold of TVC and TVB-N content in fish sample. Thus, these colorimetric indicator films could indicate the fish spoilage by visible color change. The developed colorimetric indicator film is expected to provide a convenient, non-destructive and visual method to estimate fish freshness during storage.

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.
