Area of Science:

  • Materials Science
  • Food Science
  • Environmental Science

Background:

  • Plastic pollution is a significant global environmental issue, particularly from disposable items.
  • Developing sustainable alternatives to conventional plastics is crucial for waste reduction.

Purpose of the Study:

  • To produce biodegradable spoons from natural ingredients.
  • To evaluate the texture, antioxidant activity, and polyphenol content of the biodegradable spoons.
  • To identify an optimal formulation for eco-friendly cutlery.

Main Methods:

  • Spoons were created using a mixture of water, grape, proso millet, wheat, xanthan, and palm oil.
  • Samples underwent baking at 180°C or 240°C, with some undergoing fruit dehydrator drying.
  • Texture, antioxidant activity, and total polyphenol content were analyzed.

Main Results:

  • A spoon formulation combining all three flours (grape, millet, wheat) with xanthan showed the most promising results.
  • This optimal spoon exhibited high strength and significant antioxidant activity.
  • Grape flour inclusion positively impacted the nutritional profile of the biodegradable spoons.

Conclusions:

  • Biodegradable spoons made from a blend of grape, millet, and wheat flours with xanthan are a viable alternative to plastic cutlery.
  • The developed spoons offer a sustainable solution with desirable functional properties.
  • Grape flour contributes beneficially to the nutritional quality of these eco-friendly cutlery items.
