The buriti palm (Mauritia flexuosa) is a palm tree widely distributed throughout tropical South America. The oil extracted from the fruits of this palm tree is rich in natural antioxidants. The by-products obtained from the buriti palm have social and economic importance as well, hence the interest in adding value to the residue left from refining this oil to obtain biofuel. The process of methyl esters production from the buriti oil soapstock was optimized considering acidulation and esterification. The effect of the molar ratio of sulfuric acid (H2SO4) to soapstock in the range from 0.6 to 1.0 and the reaction time (30–90 min) were analyzed. The best conditions for acidulation were molar ratio 0.8 and reaction time of 60 min. Next, the esterification of the fatty acids obtained was performed using methanol and H2SO4 as catalyst. The effects of the molar ratio (9:1–27:1), percentage of catalyst (2–6%) and reaction time (1–14 h) were investigated. The best reaction conditions were: 18:1 molar ratio, 4% catalyst and 14 h reaction time, which resulted in a yield of 92% and a conversion of 99.9%. All the key biodiesel physicochemical characterizations were within the parameters established by the Brazilian standard. The biodiesel obtained presented high ester content (96.6%) and oxidative stability (16.1 h).

This work reports a complete characterization of buriti oil. Physicochemical properties were determined according to AOCS methodologies and thermophysical properties were measured using a controlled stress rheometer and a digital electronic density meter. β-carotene and tocopherol contents were obtained using HPLC systems. Fatty acids and acylglycerol classes were determined using GC and HPSEC systems, respectively, while triacylglycerol composition was estimated using the software PrOleos. Thermal behavior (crystallization and melting) was analyzed using a DSC. The results attested high levels of total carotenoids with β-carotene as the major one; total tocopherols contained α- and β-tocopherols which accounted for 91% of the total; and monounsaturated fatty acids were mainly represented by oleic acid. The results showed close agreement between density and viscosity of buriti and olive oils. The crystallization and melting peaks occurred at -43.06 °C and -2.73 °C, respectively. These properties enable Buriti oil to be recommended as an excellent alternative for enriching foods with bioactive compounds.

Background: Buriti (Mauritia flexuosa) oil has high economic potential because it contains monounsaturated and polyunsaturated fatty acids with high antioxidant potential and high carotenoid content, making it an excellent source of pro-vitamin A. Objective: The objective of this work was to evaluate the rheological properties of filmogenic solutions incorporated with different buriti oil concentrations. Methods: Buriti oil (0.15 to 0.45 % w/v) and emulsifier (Tween®20) (0.02 to 0.04 % w/v) were combined using a factorial experimental design 22 with 3 central points for the preparation of filmogenic solutions with cassava starch (3%, w/v) and glycerol (0.06%, w/v). Rheological properties, static and centrifugation emulsion stabilities, and pH value of filmogenic solutions were evaluated. Results: Filmogenic solutions with lower emulsifier concentration showed increased flow resistance and non-Newtonian and pseudoplastic behavior (n<1). Central point formulation (E, F, and G) remained stable (no particle agglomeration) throughout the test period as well as pH value close to neutrality. In centrifugation stability index at 3500 rpm, only formulation C did not show phase separation. Conclusion: It was possible to develop a mixture of a filmogenic solution containing buriti oil that could be applied as an eco-friendly coating in food.
