Determinou-se a composição de ácidos graxos, por cromatografia em fase gasosa, do óleo da semente do maracujá amarelo (Passiflora edulis f. flavicarpa), em três diferentes tamanhos de frutos (tipo 1 = 1215 cm; tipo 2 = 710 cm; tipo 3 = 56 cm). O rendimento das sementes em relação ao peso dos frutos para os tipos 1, 2 e 3 (5,18; 5,83 e 5,31%) e para a polpa dos tipos 1 e 3 (12; 17 e 12,67%) não apresentou diferença entre os tamanhos analisados, com exceção do tipo 2 (14,03%) para polpa que evidenciou maior rendimento. A composição em ácidos graxos do óleo da semente do maracujá amarelo, nos três diferentes tamanhos, mostrou predominância de ácidos graxos oléico e linoléico. O método mais adequado para a determinação da composição de ácidos graxos do óleo do maracujá foi o Cd 14c94/ coluna SP 2340 da American Oil Chemists’ Society. Abstract Fatty acids composition was determined in three different sizes (type 1=1215 cm; type 2=710 cm; type 3=56cm) of yellow passion fruit (Passiflora edulis f. flavicarpa) oil using gas chromatography. The seed yield in terms of fruit weight to types 1, 2 and 3 (5,18; 5,83 and 5,31%) and fruit pulp to types 1 and 3 (12,17 and 12,67%) didn’t present differences between the sizes analyzed with the exception of fruit pulp type 2 (14,03%) that showed the highest yield. The fatty acids composition of yellow passion fruit oil, in three different sizes, showed a predominance of oleic and linoleic acids. The more suitable methodology for passion fruit oil fatty acids determination was AOCS Cd 14c94/ column SP 2340.

The textural properties of butter are influenced by its fat content and implicitly by the fatty acids composition. The impact of butter’s chemical composition variation was studied in accordance with texture and color properties. From 37 fatty acids examined, only 18 were quantified in the analyzed butter fat samples, and approximately 69.120% were saturated, 25.482% were monounsaturated, and 5.301% were polyunsaturated. The butter samples’ viscosity ranged between 0.24 and 2.12 N, while the adhesiveness ranged between 0.286 to 18.19 N·mm. The principal component analysis (PCA) separated the butter samples based on texture parameters, fatty acids concentration, and fat content, which were in contrast with water content. Of the measured color parameters, the yellowness b* color parameter is a relevant indicator that differentiated the analyzed sample into seven statistical groups; the ANOVA statistics highlighted this difference at a level of p < 0.001.
