“…6 Previous studies identified long-chain aliphatic primary alcohols (policosanol), phytosterols (stigmasterol, β-sitosterol), triterpenoids, wax esters, aldehydes, and fatty acids in sugarcane-derived waxes. 1,9 Thus, phytosterols are valued as antioxidants due to their free radical scavenger capacity. 10 Moreover, the hypocholesterolemic effects of phytosterols and the anti-obesity properties of octacosanol have also been evidenced in previous studies.…”

Saccharum officinarum L. exploitation and processing result in different byproducts, such as filter cake (FC). This study aimed to establish the most suitable experimental conditions to obtain lipophilic bioactive compounds from FC industrial residues, considering their high efficiency, cost-effectiveness, extraction yield, composition, and physicochemical properties. Results indicated that the most appropriate methodology consisted of the pretreatment of the FC sample with H 2 SO 4 , followed by ethanolic extraction (B6 method), avoiding energy-consumption FC drying steps and providing ethanol recovery (approx. 90%). The obtained B6 extract yield was 9.59 ± 0.27 g/100 g of FC dry weight, and this methodology proved to be more efficient in obtaining fatty alcohols (20.28 ± 1.48 g/kg extract) and phytosterols (31.56 ± 0.18 g/kg extract) while maintaining lower total monosaccharide concentration (26.19 ± 1.82 mg/g extract). Furthermore, the geographically related multivariate analysis in wax composition and antioxidant activity was evaluated by comparing B6 waxes from Guariba (G) and Univalem (U), both provided by Brazil and collected in June 2020. Overall, the wax composition is affected, but the antioxidant activity is uncompromised, which indicates that the optimized wax extraction method can be applied to FC.

Sugarcane wax is a co‐product with strong potential. It contains several bioactive components that can be used for pharmaceutical and cosmetic purposes. It is also considered a substitute for leading vegetable waxes in the international market. The extraction and refining technologies that have been reported in Cuba do not always manage to deliver a wax that meets the quality demanded by the market. This problem can be solved with the development of innovative technologies that allow increasing yields, higher quality, and the reduction of costs. The main objective of this work was to achieve a validated model of the Cuban sugarcane wax‐refining process using the SuperPro Designer simulator, and to evaluate the alternatives in order to reduce consumption rates and increase stability in the final product quality, as customers demand. The model successfully replicated 39 out of 44 variables used for process validation, with values falling within the historical range of the process. Deviations from historical values were less than 4 percentage points. Among the proposed modifications, the second of the two alternatives proposed resulted in lower consumption rates and more consistent quality of refined wax.

Sugarcane (Saccharum officinarum L.) leaf is an abundant waste from agriculture. In this study, we prepared binderless fiberboards from sugarcane leaf with <3 % moisture (w/w) and <1 mm in size by hot‐pressing temperature in the 210–240 °C range, followed by surface coating with polyurethane. The effect of hot‐pressing temperature on the modulus of elasticity (MOE), modulus of rupture (MOR), internal bonding (IB) strength, and thickness swelling of the binderless sugarcane leaves was investigated. An optimal pressing condition for preparing the binderless sugarcane leaf fiberboards was 230 °C for pressing temperature, 5 MPa for pressing pressure, and 600 s for pressing time, giving 1200 kg m−3 for board density, MOE of 657.1 MPa, MOR of 7.04 MPa, and IB strength of 0.277 MPa. The thickness swelling of the coated samples was almost completely eliminated by the surface coating.
