Plastics are mixtures of organic polymers that play a major role in environmental contamination worldwide. One way to reduce the waste arising from the use of plastics, especially disposable ones, can be to produce environmentally friendly cutlery. The aim of the work was the production of biodegradable spoons and evaluation of their texture, antioxidant activities and total polyphenols content. The spoons were made from a combination of the following ingredients: water, grape, proso millet, wheat, xanthan and palm oil in different concentrations. The samples were baked at 180 or 240 °C, some spoons were dried in a fruit dehydrator. According to the results of the analysis, a spoon prepared from a mixture of all three flours and with the addition of xanthan appears to be the most suitable replacement for plastic cutlery. This spoon showed high strength and antioxidant activity. It was confirmed that the use of grape flour has a beneficial effect on the nutritional profile of the experimentally produced biodegradable spoons.
塑料是有机聚合物的混合物，在全球环境污染中起着主要作用。减少塑料使用产生的废物，尤其是一次性塑料废物的一种方法是生产环保餐具。这项工作的目的是生产可生物降解的勺子，并评估其质地、抗氧化活性和总多酚含量。勺子由以下不同浓度的成分组合制成：水、葡萄、黍、小麦、黄原胶和棕榈油。样品在180或240°C下烘烤，一些勺子在水果脱水机中干燥。根据分析结果，由所有三种面粉混合并添加黄原胶制成的勺子似乎是塑料餐具最合适的替代品。这种勺子具有高强度和抗氧化活性。已证实使用葡萄粉对实验生产的可生物降解勺子的营养成分有有益影响。
