Summary

This summary is machine-generated.

This study introduces a green 3D printing method for intelligent labels using blueberry anthocyanins and gallic acid, enhancing color stability and food freshness detection.

Area Of Science

  • Food Science
  • Materials Science
  • Biotechnology

Background

  • Anthocyanins are used in intelligent labels but degrade under heat during preparation.
  • Color fading in labels reduces their sensitivity for detecting changes like food spoilage.

Purpose Of The Study

  • To develop a green 3D printing technique for stable, sensitive intelligent labels.
  • To enhance blueberry anthocyanin (BA) color stability using gallic acid (GA) co-pigmentation.
  • To validate the application of these labels for food freshness monitoring.

Main Methods

  • Developed a green 3D printing technique for intelligent labels.
  • Incorporated gallic acid (GA) into blueberry anthocyanin (BA) solutions for co-pigmentation.
  • Characterized ink viscosity and structural interactions using analytical techniques.
  • Tested label performance in monitoring sea shrimp freshness.

Main Results

  • GA-BA co-pigmentation reduced anthocyanin fade rate from 35.13% to 26.44% at 90°C.
  • 3D printing ink exhibited shear-thinning properties with yield stress of 500-600 MPa.
  • Co-pigmentation improved interactions between ovalbumin and cassava starch.
  • Labels successfully indicated sea shrimp freshness.

Conclusions

  • GA-BA co-pigmentation is an effective strategy to enhance intelligent label color stability.
  • 3D printing offers a sustainable and customizable method for producing intelligent labels.
  • These labels show promise for real-time food freshness monitoring applications.
