The essential oils extracted from the peels of two Tuscany of the Massa province have been characterised. Moreover, the flavedo of these species has been used in the production of two olive oils (OOs) obtained with an innovative method in which the citrus peels are cryomacerated and then pressed with the olives. The presence of functional compounds, such as carotenoids, naringenin and minor phenolics, classifies these OOs as nutraceuticals with the potential to develop enriched foods able to promote a healthy diet. Moreover, the increased presence of tyrosol and hydroxytyrosol, compared to the unflavoured oil, further highlights the nutritional value to the two OOs, being these phenolic compounds recognized as good possible therapeutic candidates for the inhibition of neurodegenerative diseases as the Parkinson's disease. In this perspective, the citrus peels, rich in bioactive compounds, have been valued transforming their waste nature in an innovative resource.
从托斯卡纳省马萨的两种柑橘皮中提取了精油，并对其进行了特征描述。此外，这两种物种的果皮被用于生产两种橄榄油（OO），这种方法是创新的，其中将柑橘皮进行冷冻-研磨，然后与橄榄一起压榨。功能性化合物的存在，如类胡萝卜素、柚皮苷和少量类黄酮，将这些 OO 归类为具有开发潜力的营养保健品，能够生产出富含营养的食品，促进健康饮食。此外，与未调味的油相比，两种 OO 中酪氨酸和羟基酪醇的含量增加，进一步凸显了它们的营养价值，这些酚类化合物被认为是抑制神经退行性疾病（如帕金森病）的良好潜在治疗候选物。从这个角度来看，富含生物活性化合物的柑橘皮已被视为一种创新资源，其废物性质已得到转化和利用。
