    An experiment was conducted to examine the effects of supplementing feed with hesperidin or naringin, bioflavonoids that are abundant and inexpensive by-products of citrus cultivation, on lambs’ growth performance, carcass and meat characteristics. Fourty-four male Chios lambs were randomly assigned to 4 groups. One of the groups served as control (C) and was given a basal diet, whereas the other 3 groups were given the same diet further supplemented with hesperidin at 2500 mg (H), or naringin at 2500 mg (N), or α-tocopheryl acetate at 200 mg (E) per kg feed. At the end of the experiment (35th day), lambs were fasted, weighed and slaughtered. After overnight chilling, samples of longissimus thoracis muscle were taken and were used for meat quality evaluation. No significant differences were observed in final body weight, body weight gain and edible organ weights among the four experimental groups. pH, colour parameters (L, a*, b*), water holding capacity and shear force value of longissimus thoracis muscle were also not significantly influenced by the dietary treatments. Measurement of lipid oxidation values showed that hesperidin or naringin supplementation positively influenced meat antioxidant properties during the refrigerated storage at 4°C for up to 8 days, however to a lesser extent compared to α-tocopheryl acetate. Nowadays, there is a strong interest in isolating antioxidants from natural sources and using them in animal nutrition with the intention to minimize lipid oxidation in meat products. According to the findings of the present study, flavonoids appeared as a great alternative, since they resulted in an improvement of meat antioxidant capacity leading to a prolongation of its shelf-life and an increase of its acceptability in the market

    An experiment was conducted to examine the effects of supplementing broiler feed with hesperidin or naringin, on growth performance, carcass characteristics, breast meat quality and the oxidative stability of breast and thigh meat. Two hundred and forty 1-day-old Ross 308 broiler chickens were randomly assigned to 6 groups. One of the groups served as a control (C) and was given commercial basal diets, whereas the other five groups were given the same diets further supplemented with naringin at 0.75 g/kg (N1), naringin at 1.5 g/kg (N2), hesperidin at 0.75 g/kg (E1), hesperidin at 1.5 g/kg (E2) and a-tocopheryl acetate at 0.2 g/kg (E). At 42 days of age, 10 chickens per treatment group were slaughtered for meat quality and oxidative stability assessment. No significant differences were observed among groups in final body weight, carcass weight and internal organs weights (P>0.05) apart from liver that decreased linearly with increased levels of naringin (P-linear0.05). Measurement of lipid oxidation values showed that after hesperidin and naringin dietary supplementation, malondialdehyde values decreased in tissue samples in a dose depended manner (P-linear<0.05). In conclusion, hesperidin and naringin, positively influence meat antioxidative properties without negative implications on growth performance and meat quality characteristics in poultry, thus appearing as important additives for both the consumer and the industry

    Hesperidin and naringin are bioflavonoids known for their antioxidant properties. They are abundant in inexpensive by-products of citrus cultivation such as citrus pulp which often are treated as waste. An experiment was conducted to examine the effects of dietary hesperidin or naringin supplementation on lactating ewes’ milk antioxidant capacity

    To date numerous metabolomic studies have been performed in order to characterize nutritional intervention studies. The aim of the current study was to present a comprehensive pipeline for characterizing the metabolic changes that occur in chickens tissues in response to naringin and hesperidin dietary supplementation. Forty-nine chickens were randomly divided into 3 groups: the first one fed with diet supplemented with naringin, the second with hesperidin whereas the control group was fed by commercial basal diet. After 30 days of administration chicken muscle samples were analyzed by UHPLC–HRMS whereas data were analyzed by the proposed pipeline. Three significant variables were detected to discriminate the control from the group after naringin administration and thirteen variables after hesperidin supplementation. Furthermore, a more detailed pipeline (encompassing multiple internal standards, internal validation of the clustering, extended statistical significance scores and multiple identification procedures) has been proposed aiming towards a more accurate untargeted analysis. © 201

    Development and validation of a UPLC–ESI(-)–MS/MS methodology for the simultaneous quantification of hesperidin, naringin, and their aglycones in chicken tissue samples

    Background: The dietary supplementation of livestock with antioxidants to improve the meat quality represents an active research area of high commercial impact. In order to investigate the optimal dosing, analytical methodologies need to be developed in various tissues to evaluate which concentration does remain in the tissue. Objective: We aimed to develop and validate a sensitive and specific methodology for the simultaneous quantitative determination of hesperidin, naringin, hesperetin, and naringenin in chicken tissue samples employing ultra-performance LC–tandem MS. Methods: Lipid extraction using cold chloroform was performed followed by protein precipitation by cold acetone. Chromatography was performed on a C18 column using a ternary gradient of water, acetonitrile, and isopropanol–acetonitrile–acetone (58+40+2, v/v) as the mobile phase. Detection was performed by electrospray ionization in negative ion mode with the selected reaction monitoring technique. Results: Calibration plots exhibited good linearity (r2 &amp;gt; 0.99) over the concentration range from 0.125 to 25 μg/g tissue for the four analytes, and the lower LOQ for the four analytes was 0.125 μg/g tissue. The repeatability as percent relative SD and precision as percent accuracy were &amp;lt;20 and &amp;gt;80%, respectively. Conclusions: The developed methodology was applied for the quantitative determination of hesperidin, naringin, hesperetin, and naringenin in tissue samples after dietary supplementation with 1.5 g/kg hesperidin and 1.5 g/kg naringin in Ross 308 broiler chickens. Highlights: This is the first methodology to access naringin, naringenin, hesperidin, and hesperetin in chicken tissue. It involved simple sample preparation, and the mass spectrometry based detection ensures high specificity and sensitivity. © 2020 AOAC International. All rights reserved

    Development of a Validated UHPLC-ESI (-)-HRMS Methodology for the Simultaneous Quantitative Determination of Hesperidin, Hesperetin, Naringin, and Naringenin in Chicken Plasma

    A highly sensitive and specific methodology has been developed for the simultaneous determination of the flavonoids hesperidin, hesperetin, naringin, and naringenin in chicken plasma employing UHPLC-HRMS (Orbitrap Velos). Plasma samples were preprocessed by protein precipitation with cold acetone. Analysis was carried out on an INTERCHIM UHPLC C18 column using aq. 0.1% glacial acetic acid, acetonitrile, and isopropanol/acetonitrile/acetone (58/40/2, v/v) as the mobile phase. Detection was performed by means of electrospray ionization (ESI) in the negative ion. All calibration curves exhibited good linearity (r 2 &amp;gt; 0.990) over the concentration range of 0.005 to 1 μg/mL with a lower limit of quantification (LLOQ) of 0.005 μg/mL for the four analytes. The repeatability and precision were within %RSD &amp;lt; 20 and accuracy within %Error &amp;lt; 20. No matrix effect or carry over was observed for the proposed methodology. Furthermore, as the quantitation procedures employing an Orbitrap analyzer are yet not well established, the impact of various parameters of MS/MS-based quantitation has been examined in order to achieve analytically solid results. The methodology was applied in plasma samples after dietary supplementation with 0.75 g/kg of feed (low-dose treatment) and 1.5 g/kg of feed (high-dose treatment) of hesperidin and naringin in Ross 308 broiler chickens. © 2019, Springer Science+Business Media, LLC, part of Springer Nature
