Autoria: FREITAS-SILVA, O.; COSTA, R. A.; CORREA, T. B. S.; FARIAS, A. X. de; ROCHA, E. dos S.; FRAGA, M. E. F. Conteúdo: Para avaliar a ocorrência da população fúngica em toda cadeia do café, abrangendo a micobiota externa e mesocarpo dos frutos, além da parte interna dos grãos, foram utilizados os meios de cultura de batata dextrose– ágar (BDA) e DG18. Este estudo foi conduzido na Embrapa Agroindústria de Alimentos, em 174 amostras de cafés de vários tipos, procedentes de processamento via seca e via úmida, além de frutos cerejas colhidas no pé e do café de varrição. As coletas foram realizadas em 24 propriedades durante a safra de 2002 nos Estados de Minas Gerais, Goiás e Bahia, em regiões com características típicas do cerrado brasileiro, além de Rondônia (café robusta).

Autoria: VIANA, J. dos S.; LOURINHO, J. M. P.; BRILHANTE, N. S.; ANTONIASSI, R.; FARIA-MACHADO, A. F. de; WILHELM, A. E.; BIZZO, H. R. Conteúdo: The profile of fatty acids is an important marker for the identity of olive oils. Eleven samples of monovarietal Arbosana Brazilian olive oils were analyzed. Three did not pass the regulation limits, but experimental evidence from other regions points out this may be due to edaphoclimatic variations in plant metabolism, rather than adulteration.

Autoria: LOURINHO, J. M. P.; VIANA, J. dos S.; BRILHANTE, N. S.; ANTONIASSI, R.; FARIA-MACHADO, A. F. de; WILHELM, A. E.; BIZZO, H. R. Conteúdo: The content of biophenols and tocopherols in 18 Brazilian extra virgin olive oils from six cultivars was analyzed by UPLC-UV-MS. Secoiridoids were the main phenolics found. Alpha-tocopherol corresponded to c.a. 80 % of total tocopherols. Commercial production of olive oil in Brazil has started recently and is concentrated especially in the states of Rio Grande do Sul and Minas Gerais States. It has experienced a constant growing, although it corresponds to only 1% of internal market. Phenolic compounds and tocopherols are important for the oxidative stability of olive oils. As any product from plant origin, chemical composition is dependent on the plant genetics (cultivars, in this case), as well as on the edaphoclimatic conditions where cultivation took place. Herein, we report the results of biophenolics and tocopherols from olive oils of the cultivars Coratina, Frantoio, Galega, Grappolo, Manzanilla and Picual produced in Minas Gerais (MG) and Rio Grande do Sul (RS) states.

Autoria: SANTOS, M. C.; LIMA, K. S. C.; FREITAS-SILVA, O.; OLIVEIRA, S. E. M.; SOUSA, R. B.; LIMA, A. L. S. Conteúdo: In this work we performed the extraction of essential oils from Nutmegs produced in Brazil and Thailand, through hydrodistillation with a Clevenger modified apparatus. With the use of two-dimensional chromatography, coupled to a mass spectrometer, CG-CG/MS, analyzes were performed of its composition, illustrating a distinct difference between the nuts according to their different origins.
