Capillary gas chromatographic analysis of aroma extracts obtained by simultaneous distillation-extraction from yellow passion fruits (Passiflora edulis f. flavicarpa) using a flame photometric detector revealed the presence of previously unreported sulfur-containing volatiles. 3-Mercaptohexanol and the acetates, butanoates, and hexanoates of 3-mercaptohexanol and 3-(methylthio)hexanol, respectively, were identified by comparison of chromatographic and mass spectral data with those of synthesized reference compounds.

The formation of volatile C8 components and less volatile C10 (Cn) oxo and hydroxy acids was investigated in fresh mushrooms (Agaricus campestris). The components were isolated from the mushrooms by distillation-extraction and liquid-liquid extraction and analyzed by capillary gas chromatography-mass spectrometry. Further characterization was made by infrared spectroscopy, NMR spectroscopy, chemical reactions, and Me3Si derivatizations. After addition of linoleic and linolenic acids, the following components were identified for the first time in mushrooms: (Z)-2-octenal, (Z)-l,5-octadien-3-one, (Z)-l,5-octadien-3-ol, (Z,Z)-2,5-octadienal, and (Z,Z)-2,5-octadien-l-ol (partly showing intensive mushroom-like odors). 10-Oxodecanoic acid, 10-hydroxydecanoic acid, 10-oxoundecanoic acid, 10hydroxyundecanoic acid, 10-oxo-8-decenoic acid, 10-hydroxy-8-decenoic acid, 9-oxodecanoic acid, and 9-hydroxydecanoic acid were characterized as enzymatic products from linoleic acid.

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on 2'-fucosyllactose/difucosyllactose (2'-FL/DFL) mixture as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is a powdered mixture mainly composed of two oligosaccharides, 2'-FL and DFL, which are produced together by fermentation with a genetically modified strain of Escherichia coli K12. The information provided on the manufacturing process, composition and specifications of the NF does not raise safety concerns. The applicant intends to add the NF in a variety of foods, including infant and follow-on formula, foods for infants and young children, foods for special medical purposes and food supplements. The target population is the general population except for food supplements, for which the target population is individuals above 1 year of age. Since the intake of 2'-FL and DFL from the NF at the proposed use levels is unlikely to exceed the intake level of naturally occurring 2'-FL and DFL in breastfed infants per kilogram body weight, the Panel concludes that the NF, a mixture of 2'-FL and DFL, is safe under the proposed conditions of use for the proposed target population.
