The use of olive pomace from olive oil production is still insufficient. The lingering olive pomace is harmful to the environment. On the other hand, the world is increasingly polluted with plastic or by-products from the production of biodegradable products. Considering these two problems, the aim of this work was to develop a mixture and create biodegradable disposable tableware characterized by high antioxidant activity. The disposable tableware was made by mixing olive pomace with teff flour or/and sorghum groats and lecithin. Baking was carried out at the temperature of 180 °C. The best variant of the mixture for the preparation of disposable tableware was olive pomace, teff flour, sorghum groats and lecithin. These vessels were the toughest, with low water absorption and had a high antioxidant potential due to the high content of polyphenols and omega acids. Protecting the cups and bowls with beeswax had a positive effect on reducing water absorption.
橄榄油生产过程中橄榄果渣的利用仍不充分。残留的橄榄果渣对环境有害。另一方面,世界正日益受到塑料或可生物降解产品生产副产品的污染。考虑到这两个问题,这项工作的目的是开发一种混合物,并制造出具有高抗氧化活性的可生物降解一次性餐具。一次性餐具是通过将橄榄果渣与画眉草面粉或/和高粱碎粒以及卵磷脂混合制成的。烘焙在180°C的温度下进行。用于制备一次性餐具的混合物的最佳配方是橄榄果渣、画眉草面粉、高粱碎粒和卵磷脂。这些容器最坚固,吸水性低,由于含有高含量的多酚和欧米伽酸,具有很高的抗氧化潜力。用蜂蜡保护杯子和碗对降低吸水性有积极作用。
