Evaluation of fatty acid profiles and mineral content of grape seed oil of some grape genotypes

AbstractThis work focused on physicochemical property assaying, fatty acid composition, triacylglycerol profiles, and sterols and squalene composition of the Chinese grape seed oil. Three different methods were used to extract oil from Chinese grape seeds, solvent extraction, cold press and hot press methods. Three oils all possess very low acid value and peroxide value, suggesting their good quality as edible oil. Fatty acid composition results indicated that the total content of unsaturated fatty acids was 89.14 %, within which the majority fatty acid was linoleic acid with content of 64.11 %. Characterization of triacylglycerol profiles was achieved by a two-dimensional HPLC coupling of nonaqueous reverse-phase and silver ion HPLC with atmospheric pressure chemical ionization mass spectrometry method. There was a total of 30 TAGs including 23 regioisomers that have been determined. Unsaponifiable matters composition results revealed that the total sterols content and the squalene content were 278.49 mg/100 g and 17.81 mg/100 g, respectively.

The purpose of this study was to evaluate the effects of grape seed oil (GSO) supplementation to broilers fed polyunsaturated fatty acids (PUFA)-enriched diets on growth performance, color, texture, fatty acid content and lipid peroxidation of meat. The 4-week feeding trial was conducted on 120 Cobb 500 broilers, assigned to three groups and housed in an experimental hall on permanent wood shaves litter. GSO was tested as source of natural antioxidants at different levels, 0% (GSO0, control), 1.5% (GSO1.5) and 3% (GSO3) in the presence of 4% flaxseed meal (FSM) in a completely randomized design. The results show that at the end of the experiment (42 days) the GSO supplementation had no effect (p < 0.05) on productivity parameters, except the final weight which was improved in GSO3 compared to GSO. The thigh meat color indicated a higher degree of lightness (p < 0.05), but the meat texture was not influenced (p < 0.05) by the new tested diets. The GSO diets increased (p < 0.05) the saturated fatty acid (SFA) content and decreased the PUFA content in the thigh meat. Thigh meat samples from GSO treatments had significantly (p < 0.05) improved oxidative stability. In the breast meat only the concentration of thiobarbituric acid-reactive substances (TBARS) decreased (p < 0.05). It is concluded that the GSO significantly improved the thigh meat oxidative stability.

The main objective was to determine the chemical, phytochemical, fatty acid and mineral profiles of three commercially relevant brown macroalgae (Laminaria digitata, Laminaria hyperborea and Ascophyllum nodosum) collected each season for two years off the west coast of Ireland. All the chemical, phytochemical, fatty acid and minerals analysed varied significantly depending on the macroalgal species, season and year of collection. Overall, the protein contents of macroalgae were negatively correlated with carbohydrate content. Protein (2–11%) was at its highest during winter and/or spring, decreasing to a minimum during summer and/or autumn. The three macroalgal species analysed in this study had clearly differentiated fatty acid profiles. The concentration of fatty acids was higher in A. nodosum compared with both Laminaria species. The mineral profile of the three macroalgal species was rich in essential metals, particularly Ca, Mg and P, while the levels of I were approximately 9- to 10-fold higher in both Laminaria spp. compared with A. nodosum. The levels of toxic metals (Cd, Hg and Pb) in all the macroalgal species studied were low in the current study; while the levels of total As were high (49–64 mg/kg DW macroalgae) compared with previous reports.

Grape Seed Oil

The current study focused on investigating the renoprotective effects of grape seed oil (GSO) against hexavalent chromium (Cr (VI))-induced nephrotoxicity. A total of 40 male rats were randomly divided into four groups: group I served as the control group, group II received 1000 mg/L potassium dichromate (353.5 mg/L Cr(VI)) in drinking water for 12 weeks, group III received 3.7 g/kg body weight/day GSO orally for 12 weeks, and group IV received GSO together with potassium dichromate for 12 weeks. Cr(VI) significantly increased serum levels of urea, creatinine, potassium and glucose. In addition, Cr(VI) increased MDA levels and induced renal tissue damage and DNA damage. On the other hand, Cr(VI) decreased serum levels of sodium and antioxidant defence system [reduced glutathione (GSH) and catalase (CAT)]. However, treatment with GSO prevented elevation levels of serum urea, creatinine, potassium and glucose. In addition, GSO enhanced sodium level, renal tissue antioxidant defense system due to its curative effect ameliorated particularly oxidative stress, renal tissue and DNA damage. In conclusion, these results demonstrate that GSO is a promising nephroprotective agent against Cr(VI)-induced nephrotoxicity.Key words: grape seed oil; hexavalent chromium; nephrotoxicity; DNA damage BLAŽILNI UČINKI OLJA GROZDNIH PEŠK PRI TOKSIČNI OBREMENITVI LEDVIC TER VPLIV NA OKSIDATIVNI STRES PODGAN, POVZROČEN S KROMOM Povzetek: Študija je bila osredotočena na proučevanje zaščitnih učinkov olja grozdnih pešk (GSO) pri toksični obremenitvi ledvic, povzročeni s heksavalentnim kromom (Cr (VI)). Štirideset samcev podgan je bilo naključno razdeljenih v štiri skupine: skupina I - kontrolna skupina, skupina II, ki je v pitni vodi 12 tednov prejemala 1000 mg/L kalijevega dikromata (353,5 mg/L Cr (VI)), skupina III, ki je peroralno 12 tednov prejemala 3,7 g/kg telesne mase/dan GSO ter skupina IV, ki je 12 tednov prejemala GSO skupaj s kalijevim dikromatom. Cr(VI) je znatno zvišal serumske ravni sečnine, kreatinina, kalija in glukoze v serumu. Poleg tega je Cr(VI) zvišal raven MDA in povzročil poškodbe ledvičnega tkiva in poškodbe DNK. Po drugi strani je Cr(VI) znižal serumsko raven natrija in antioksidativnega obrambnega sistema, zmanjšal raven glutationske peroksidaze in katalaze. Dodajanje GSO poskusnim živalim je preprečilo zvišanje ravni sečnine v serumu, kreatinina, kalija, natrija in glukoze. Poleg tega je GSO izboljšal obrambni sistem antioksidantov ledvičnega tkiva. Zaradi svojega zdravilnega učinka je izboljšal zlasti oksidativni stres, poškodbe ledvičnega tkiva in DNK. Rezultati kažejo, da je GSO obetavno zaščitno sredstvo za ledvica pri toksični obremenitvi, povzročeni s Cr(VI).Ključne besede: olje grozdnih pešk; heksavalentni krom; nefrotoksičnost; poškodba DNK

Grape Varieties

In this study, we examined the yield and oil quality of eight different grape varieties. For the experiments, the grape seeds were obtained from the Benedictine Pannonhalma Archabbey in the northwestern region of Hungary. The aim of the studies was to determine the oil yield obtained by extraction and to examine the differences between the fatty acid composition, antioxidant capacity, and total polyphenol content of the oils of different grape varieties. Based on the results, the oil content of the grape seeds varied between 99.91 g/kg and 126.74 g/kg. The grape seed oils analysed contained significant amounts of stearic acid (3.42–9.93%), palmitic acid (7.81–10.66%), oleic acid (14.29–19.92%), and linoleic acid (66.85–72.47%). Besides, the grape seed oils tested contained several other fatty acids in small amounts. There were significant differences in the total antioxidant and total polyphenol content of the oils. Total polyphenol content ranged from 0.24 to 1.13 mg GAE/g, while the total antioxidant content changed between 0.12 and 0.78 μg TEAC/g. The results show that the studied varieties are suitable for the production of table grape seed oil based on their oil yield, and the oils have favourable, health-protecting properties in terms of their quality.
