*2.1. Materials*  The Brazil nuts used in this work were of Brazilian origin and were purchased from FrutoSeco (Alicante, Spain). On the other hand, the hemp seeds were obtained from a local market in Callosa de Segura (Alicante, Spain). The oil from both seeds was extracted by cold pressing with an extruder model DL-ZYJ05 purchased from Nanchang Dulong Industrial Company (Zucheng, China). The density of Brazil nut oil was 916 kg·m−3, its iodine value (IV) between 99.5 and 102.6 g 100 g−1 and its acid value (AV) 0.2 mg·KOH g−1. The density of hemp oil was 935 kg·m−3, its IV is 163.8 g·100g−1 and its AV is 8 mg·KOH g−1. For both cases, density, IV and AV values were obtained according to ISO 1675, ISO 3961 and ISO 660, respectively. For the maleinization of both oils, maleic anhydride supplied by Sigma Aldrich (Madrid, Spain), with a purity of 98% was used. The PLA used for mixing with the oils was a commercial-grade Ingeo Biopolymer 2003D from NatureWorks The Brazil nuts used in this work were of Brazilian origin and were purchased from FrutoSeco (Alicante, Spain).
