Abstract

In the context of the anti-plastic law in Colombia and with the aim of developing sustainable and environmentally friendly alternatives, the utilization of cocoa pod husk (CPH), the most abundant agricultural by-product during cocoa post-harvest, which represents between 70 and 80% of the total fruit weight, was explored. The production of biopolymers from this waste represents a significant step toward a circular economy in the cocoa value chain. This study evaluated the functionality of cellulose extracted from CPH and its suitability for biocomposite film production, comparing its performance with biocomposite films made from commercial cellulose. Two biocomposite films were formulated using the casting method: Film A, with commercial cellulose, and Film B, with cellulose extracted from the CPH of the Colección Castro Naranjal (CCN51) clone, both containing starch, xanthan gum, cellulose, and sorbitol as a plasticizer. Several characterization analyses were conducted to evaluate their properties, including moisture content, ash percentage, water solubility, chemical resistance, oil permeability, microscopic structure and light transmittance. The results showed that CPH cellulose has properties comparable to those of commercial cellulose, confirming its potential for the development of eco-friendly biocomposite films. This approach offers an innovative and sustainable solution for the utilization of agricultural by-products and contributes to waste reduction in cocoa production processes.

从可可豆荚壳中提取纤维素制成的生物复合膜

在哥伦比亚反塑料法的背景下，为了开发可持续和环保的替代品，我们探索了可可豆荚壳（CPH）的利用，这是可可收获后最丰富的农业副产品，占果实总重量的70%至80%。从这种废物中生产生物聚合物是可可价值链中朝着循环经济迈出的重要一步。本研究评估了从CPH中提取的纤维素的功能及其用于生物复合膜生产的适用性，并将其性能与商业纤维素制成的生物复合膜进行了比较。采用浇铸法配制了两种生物复合膜：膜A采用商业纤维素，膜B采用从Colección Castro Naranjal （CCN51）克隆的CPH中提取的纤维素，均含有淀粉、黄原胶、纤维素和山梨糖醇作为增塑剂。对其进行了多项表征分析，包括含水率、灰分率、水溶性、耐化学性、渗透率、微观结构和透光性等。结果表明，CPH纤维素具有与商品纤维素相当的性能，证实了其开发生态友好型生物复合膜的潜力。这种方法为利用农业副产品提供了一种创新和可持续的解决方案，并有助于减少可可生产过程中的废物。

期刊介绍： Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
