Lipophilic composition of eleven apple seed oils: A promising source of unconventional oil from industry by-products

Chemical Composition of Seed Oils Recovered from Different Pear (Pyrus communis L.) Cultivars

“…1). [2,4]. The range of oil yield reported in different apple seeds is almost identical with the values found in present study in pear seeds.…”

“…Oil was extracted according to an earlier method [4]. In brief, ground fruit seeds (5 g) were supplemented with 25 mL of n-hexane in a centrifuge tube and mixed on a Vortex REAX top (Heidolph, Schwabach, Germany) at 2500 rpm (1 min).…”

“…Consequently, the global quantities of seeds generated during processing of those fruits are significant. Recently, a large amount of reports have highlighted the usefulness of recovering bioactive lipophilic compounds from fruit seeds (agro-industrial by-products), such as essential fatty acids [1][2][3][4], tocochromanols [1,3,[5][6][7][8], carotenoids [3,8], phytosterols [1,3,4] and squalene [1,4]. Environmental, economical and nutritional factors have been the main driving forces behind scientific characterization of agro-industrial by-products for alternative use.…”

Phenolic compounds in different fruit parts of crab apple: Dihydrochalcones as promising quality markers of industrial apple pomace by-products

“…However, previous studies on polyphenols only took into account the apple pomace as a whole plant material (sample), without separating and investigating the different parts of apple fruit (seeds, stems, flesh, peel and core). Recently, a number of studies have illustrated the importance of apple seeds with the detailed composition of fatty acids and sterols (Górnaś et al, 2014a), tocopherols (Górnaś, 2015;Górnaś et al, 2014b) and phenolic compounds (Fromm et al, 2012;Fromm et al, 2013) observed. To date, there is no information about the phenolic composition of other apple fruit parts, e.g., stems, which are a part of the industrial apple by-products, since they are not removed from apples before pressing of juice.…”

Composition of tocochromanols in the kernels recovered from plum pits: the impact of the varieties and species on the potential utility value for industrial application

“…Finding of potential utilization and/or application of fruit pits is a huge challenge for the industry sector. The fruit seeds and kernels are a rich source of oil [4][5][6][7][8] and components with high biological activity, for instance, tocopherol and tocotrienol homologues (tocochromanols) [9][10][11]. Nevertheless, the plum kernels contain also the amygdalin (cyanogenic glycoside), which is potentially toxic in the presence of enzymes (β-glucosidases and α-hydroxynitrile lyases), resulting in the releasing of hydrogen cyanide [12].…”
