Utilization of Cacao Pod Husk (Theobroma cacao l.) as Activated Carbon and Catalyst in Biodiesel Production Process from Waste Cooking Oil

Investigating the role of solvent type and microwave selective heating on the extraction of phenolic compounds from cacao (Theobroma cacao L.) pod husk

“…Rather than being wasted, the unexploited CPH has a high potential to be valorised as it contains protein, carbohydrate, lipid, lignocellulosic compounds, pectin, alkaloid, and phenolic compounds, including anthocyanidins and pigment (Campos-Vega et al, 2018;Lecumberri et al, 2007;Nguyen, 2015;Nguyen et al, 2021;Valadez-Carmona et al, 2017;Vriesmann et al, 2012Vriesmann et al, , 2011. Therefore, various studies have provided evidence of the potential for CPH to be valorised as adsorbents (Rachmat et al, 2018;Tsai et al, 2020), bioenergy (Adjin-Tetteh et al, 2018;Kilama et al, 2019), anti-biofouling agent (Wibisono et al, 2021), and food additives: antioxidant (Karim et al, 2014a(Karim et al, , 2014bMartínez et al, 2012;Teboukeu et al, 2018;Valadez-Carmona et al, 2017;, colourant pigment (Nguyen, 2015), pectin-emulsifying and gelling agents Petkowicz, 2013, 2017; based on their bioactive compounds.…”

Ảnh hưởng của dung môi và phương pháp trích ly đến khả năng chiết tách các hợp chất phenolics, saponins và alkaloids từ vỏ quả ca cao (Theobroma cacao L.)

“…Như thế, mỗi năm lượng vỏ thải bỏ lên tới hơn 25.000 tấn vỏ quả tươi, gây lãng phí và ô nhiễm môi trường. Gần đây, đã có một số nghiên cứu tận thu nguồn phế liệu này như: làm bột và thức ăn hỗn hợp dạng đóng bánh cho bò (Newman et al, 2003), làm thức ăn cho gà nuôi lấy thịt (Donkoh et al, 1991), sản xuất phân hữu cơ (Huang et al, 2003), và sản xuất than hoạt tính (Rachmat et al, 2018).…”

Acoustic Characterization and Modeling of Silicone-Bonded Cocoa Crop Waste Using a Model Based on the Gaussian Support Vector Machine

“…At present, oil reserves are decreasing, and there is growing social concern about the environmental repercussions of both the extraction processes and the consumption of their derivative products. Therefore, some researchers look to organic cocoa waste as a source for the production of biofuels and other biopolymers [37]: for example, they can be also used as activated carbon and catalyst in biodiesel production [38,39]. The ground and pressed cocoa pod husk can be transformed into bio-pellets [40], having similar combustion characteristics and ash content in comparison to other biomass products.…”
