Sakalaus-kienėLithuanian Institute of Horticulture, LT-54333, Babtai, Kauno 30, Kaunas distr., Lithuania; e-mail: a.radzevicius@lsdi.ltFour cultivars (‘Neris’, ‘Svara’, ‘Vytėnų didieji’, ‘Jurgiai’) and one hybrid (‘Vaisa’) of to-mato (Lycopersicon esculentum Mill.) were investigated at the Lithuanian Institute of Horticulture from 2007–2008. During this investigation fruit quality and physi-ological parameters were evaluated: the lycopene and β-carotene contents, colour indices (CIE L*a*) and hue angle (h°) with chroma (C) at four diﬀerent fruit ripen-ing stages (I stage – green, II stage – beginning of ripening, III – not fully ripened, IV – fully ripened). A signiﬁcant increase in lycopene and β-carotene content ateach successive ripening stage of tomato fruit was recorded. Tomato fruit colour became darker and the ratio of red to green colour increased during the ripening process. Chroma value increased with a change of tomato colour from green to light red,  and subsequently declined at the red fruit stage, but chroma of the hy-brid ‘Vaisa’ increased at all ripening stages. External colour was expressed in terms of hue angle. All the analyzed tomato cultivars developed a similar colour when mature, with average hue angles generally being close to 40 degrees, but the culti-var ‘Neris’ had lower hue value (32 degrees).Fatty acid characterization of Finnish organic milk – a farm surveyE.

Basic feed samples were also collected and diets documented. Half of the farms (22) were certiﬁed all organic (AORG) and the other half (23) practiced organic ﬁeld farm-ing (FORG). The average number of cows and annual milk yield was 27.5 and 8560 kg/cow, respectively. Milk fatty acid (FA) compositions were analysed at University of Aarhus and are presented here. The average content of FA was 3.34 g/100 g and saturated FA constituted 66% of FA. The proportions of c9t11CLA and C18:3n3 av-eraged 0.48% and 0.67% of FA, respectively. The farming system had minor eﬀectson FA. Milk from AORG farms had somewhat lower proportion of C18:2, C18:3n6 and C24:1 and higher proportion of C20:0, C22:1n9 and C22:1n11 than milk from FORG farms (P<0.05). However, large range in FA between all farms challenges for further investigations of diets and feeds.
