Qualities of Native Apple Cultivar Juices Characteristic of Central Europe

Abstract

During the last century due to the changes in landscape management, in country people's lives and with intensive fruit-growing the native cultivars of apple fruit trees have been gradually disappearing. The aim of the study was to compare the juices made of native apple cider cultivars. The cultivars-'Boikovo' , 'Jadernicka moravska' , 'Kardinal zihany' , 'Panenske ceske' , 'Parmena zlata zimni' , 'Strymka' growing in the locality of the Litencicke Hills in the eastern part of the Czech Republic were selected. For comparison, the fruits of commercial 'Idared' cultivar were also included. The chemical composition, antioxidant capacity, phenols, flavonoids and ascorbic acid content and the influence of juices on scavenging activity of nitric oxide and hydroxyl radical were measured. The mutual ratio of examined properties which were found, provide information about qualities and possibilities of use of native cultivars. High antioxidant properties characterize the juice of native apple cultivars. In particular, the 'Strymka' cultivar contained 2,637.34 mg of AAE (ascorbic acid equivalent) per litre in case of antioxidant capacity. In the juice of this cultivar the value of 144.05 mg of ascorbic acid per litre was recorded. As regards the 'Panenske ceske' cultivar, antioxidant capacity was 2,548.38 mg of AAE l -1 and in relation to ascorbic acid, the value was 145.35 mg l -1 . Similarly, high values were observed in both cultivars concerning the scavenging effect of apple juices on hydroxyl radical and nitric oxide (the 'Strymka' cultivar 16.38% and 19.26%, the 'Panenske ceske' cultivar 16.31% and 18.60%).

Evaluation of Antioxidant Activity, Polyphenolic Compounds, Amino Acids and Mineral Elements of Representative Genotypes of Lonicera edulis

“…The determination of antioxidant activity, concurrently with the assessment of the main representative bioactive components in berries–polyphenolic compounds‒is one of the ways of expressing the biological value of the edible honeysuckle berries [31]. Numerous assays have been described to measure various free radical damage products or antioxidant status and the plethora of available techniques attest to the fact that no single ideal method is available [36,37,38]. In addition, levels of antioxidants in food do not necessarily reflect their antioxidant activity [39,40,41,42].…”

Bioactive compounds in sweet rowanberry fruits of interspecific Rowan crosses

“…As mentioned by many authors [1,46,47] this is a typical trait of the majority of fruit species not only in the case of antioxidant capacity of phenolics, ascorbic acid, but also where it concerns the relationship between phenolics and ascorbic acid and ROS [48,49].…”

Polyphenolic Profile and Biological Activity of Chinese Hawthorn (Crataegus pinnatifida BUNGE) Fruits

“…have recently attracted increasing attention in the field of food nutraceuticals and medicine because of their widely reported health benefits. Recent trials have demonstrated their efficacy in lowering blood cholesterol and in the reduction of the risk of cardiovascular diseases [ 7 , 11 , 12 , 13 ], which can be considered as the most significant among other lesser known fruit species [ 14 , 15 , 16 ]. Nowadays it is also well known that all these mentioned beneficial health promoting activities are connected with polyphenolic compounds and triterpene acids [ 8 ].…”
