Active and biodegradable materials have great potential in food packaging applications, improving the safety and quality of products. The objective of this study was to develop a new material based on buriti oil incorporated into a chitosan film. Different concentrations of buriti oil in dried films (2.1 g/m 2 , 10.4 g/m 2 , 20.8 g/m 2 , and 31.3 g/m 2 ) were added into a chitosan matrix (41.7 g/ m 2 ). The chitosan/buriti oil films were characterized by water-vapor barrier properties, total water-soluble matter (TSM), tensile properties, thermogravimetric analysis, microstructure, microbial permeation properties, and biodegradation estimation. The higher oil concentration improved the water-vapor barrier and the buriti oil acted largely as a plasticizer and increased the elongation at break, and decreased the tensile strength (TS) of chitosan films. The total water-soluble matter of chitosan films decreased in function of the buriti oil concentration, but the biodegradation and thermal stability increased. The chitosan films presented a microbial barrier against Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa. V C 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43210.

“…Batista et al 20 evaluated the in vitro and healing antibacterial activity of buriti oil (M. flexuosa) on wounds performed in rats (Rattus norvegicus albinus) and concluded that M. flexuosa fruit oil showed efficacy in the cicatricial process of cutaneous wounds in wistar rats , since it promoted a greater percentage of contraction of the edges of the wound and was statistically significant in the counting of fibroblasts and collagen fibers in the group treated with buriti oil in relation to the control group, besides antibacterial activity in vitro in both gram positive bacteria and in gram negative.…”

Results: The neutrophil number there was statistically significant difference, after 7 and 14 days, between groups C and MI (p <0.001) (p<0.01). The group MT there was a significant difference in relation to MI group in both experimental times with (p<0.001). The number of fibroblasts in the 14 days showed that when comparing the groups M and MT the differences were also significant (p<0.001). As for the DLL, in 7 days, there was a significant difference between group C and MI group (p <0.001). When considering the MT group, there was a significant difference in relation to the MI group (p <0.001). Conclusion:The extract of Mauritia flexuosa L. leaves lessened acute and chronic inflammation, increased fibroblast proliferation and reduced macroscopically edema.

“…Nos últimos anos, o óleo de buriti tem despertado o interesse das indústrias alimentícia e cosmética em razão das suas propriedades antibacteriana, cicatrizante e fotoprotetora. [12][13][14][15] No entanto, ainda não há estudos do seu efeito frente ao radical superóxido, uma espécie reativa de oxigênio produzida em sistemas vivos de função importante nos processos de mutagênese e carcinogênese, 16 e à α-amilase, uma enzima que possui papel chave no sistema digestivo e no controle da diabetes. 17 Além disso, pesquisas relacionadas aos frutos nativos provenientes do cerrado maranhense e suas potencialidades são escassas na literatura.…”

Buriti (Mauritia flexuosa) is a palm tree native to Brazil and the oil extracted from its fruit is used as a food and for medicinal purposes by the local population. The aim of this study was to analyze the physical, chemical, and biological characteristics of buriti oil from fruits collected in the Cerrado of Maranhão. The physicochemical parameters were analyzed according to American Oil Chemists' Society standard methods. The lipid profile and the nutritional quality indexes were determined based on the fatty acid composition obtained by gas chromatography/mass spectrometry. The levels of bioactive compounds were determined by electronic spectroscopy, and the effects of free antiradicals and antidiabetics were evaluated in vitro using the superoxide radicals and enzymatic methods with α-amylase, respectively. The buriti oil showed good physicochemical and nutritional qualities; a high content of unsaturated fatty acids and total carotenoids; and antioxidant and antidiabetic effects at low oil concentrations. These biological results and the nutritional quality indexes are unpublished data for buriti oil. Therefore, this oil potentially can be identified and used as a food ingredient and for the development of new products.
