“…A diferença entre a ação antioxidante dos extratos etanólicos de casca e de caroço, verificada na presente pesquisa, é semelhante à relatada por Freitas et al (2012), que verificaram que a adição 200 ppm de Ecas foi menos eficiente do que a de 200 ppm de Ecar, em prevenir a oxidação lipídica da carne de frango armazenada por 15 dias. Os autores relataram a dose de 400 ppm de Ecas como necessária à obtenção de efeito semelhante ao obtido com 200 ou 400 ppm de Ecar.…”

“…Entretanto, a casca e o caroço da manga são boas fontes de antioxidantes naturais (Huber et al, 2012), pois contêm diferentes componentes com essa ação, entre as quais a provitamina A, na forma de β-caroteno, e as vitaminas C e E (Puravankara et al, 2000;Abdalla et al, 2007;Ajila et al, 2007), além do composto fenol glicosilxantona, na forma de mangiferina, que tem atividade antioxidante comprovada (Puravankara et al, 2000;Bernardini et al, 2005;Abdalla et al, 2007;Barreto et al, 2008). Freitas et al (2012) relatam que a adição de 200 ou 400 ppm dos extratos etanólicos obtidos da casca ou do caroço de manga não influencia o desempenho de frangos de corte, mas podem ser mais efetivas em retardar a oxidação lipídica da carne de frangos do que o uso do antioxidante sintético BHT. No entanto, não há informação a respeito dos efeitos antioxidativos dos extratos etanólicos de manga sobre a produção e a qualidade de ovos de aves em postura.…”

Resumo -O objetivo deste trabalho foi avaliar o efeito de extratos etanólicos do caroço e da casca de manga, sobre o desempenho de poedeiras e sobre a qualidade e estabilidade lipídica dos ovos. Um total de 180 poedeiras comerciais Hisex White foi distribuído ao acaso em seis tratamentos, com cinco repetições de seis aves. Os tratamentos consistiram de: ração sem adição de antioxidante; ração com 200 ppm do antioxidante butilato de hidroxitolueno (BHT); ração com 200 ou 400 ppm de extrato da casca de manga (Ecas); ração com 200 ou 400 ppm de extrato de caroço de manga (Ecar). Foram avaliados: o consumo de ração, a produção de ovos, o peso do ovo, a massa de ovo produzida (grama por ave por dia), a conversão alimentar e características de qualidade dos ovos. A oxidação lipídica da gema durante o armazenamento foi determinada pela quantificação das substâncias reativas ao ácido tiobarbitúrico. As aves alimentadas com a ração sem adição de antioxidantes produziram ovos com os piores valores de unidade Haugh e maior oxidação lipídica da gema. Os teores de 400 ppm de Ecas e 200 ou 400 ppm de Ecar foram efetivos na prevenção de danos oxidativos aos ovos durante o armazenamento e podem ser utilizados na alimentação das poedeiras como substituto ao antioxidante sintético.Termos para indexação: Gallus gallus, Mangifera indica, antioxidante natural, mangiferina, oxidação lipídica, qualidade dos ovos. Ethanol extracts of mango as antioxidants for laying hensAbstract -The objective of this work was to evaluate the effects of ethanol extracts of mango seeds and peel on laying hen performance, egg quality, and egg lipid stability. A total of 180 Hisex White hens were randomly distributed in six treatments, with five replicates of six birds. The treatments consisted of: ration without antioxidant; ration with 200 ppm butylated hydroxytoluene (BHT); ration with 200 or 400 ppm of mango peel extract (Ecas); and ration with 200 or 400 ppm of mango seed extract (Ecar). Feed intake, egg production, egg weight, produced egg mass (gram by bird per day), feed conversion, and egg quality were evaluated. Yolk lipid oxidation during storage was determined by quantification of thiobarbituric acid-reactive substances. Birds fed diet without antioxidants produced eggs with the lowest Haugh unit values and the highest lipid oxidation of yolk. Ecas at 400 ppm and Ecar at 200 or 400 ppm were effective to prevent oxidative damage of eggs during storage and may be used in the diet of laying hens as a replacement for synthetic antioxidant.Index terms: Gallus gallus, Mangifera indica, natural antioxidant, magiferin, lipid oxidation, egg quality. IntroduçãoO ovo é uma excelente fonte de ácidos graxos essenciais que, como em qualquer alimento, estão sujeitos à oxidação lipídica, principalmente durante a estocagem (Hayat et al., 2010). Embora o processo oxidativo em ovos não seja visto como um problema, o aumento da produção de ovos enriquecidos com ácidos graxos poli-insaturados pode aumentar a suscetibilidade à peroxidação. Portanto, há necessidade ...

“…Mango waste is an alternative because the peels and seeds have appreciable amounts of unsaturated fatty acids (UFA), phenolic compounds, vitamins C and E, antioxidants and reducers of plasma triacylglycerols (TAG) levels when added to diets (ABDALLA et al, 2007;AJILA et al, 2007;FREITAS et al, 2012;HUBER et al, 2012).…”

We evaluated the effect of including 2.5, 5.0, 7.5 and 10.0% mango waste meal (MWM) variety UBA in corn and soybean meal-based diet on the serum lipid profile of broilers. The experimental design was completely randomized, with five treatments and six replicates with 20 birds per experimental unit. Concentrations of creatinine, albumin, total protein, total cholesterol, triacylglycerols (TAG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and very-low-density lipoprotein cholesterol (VLDL-C), were evaluated at the ages of 14, 28 and 42 days, with 30 birds evaluated per age. At 14 days, there was no difference serum creatinine, total cholesterol, HDL, triacylglycerols, total proteins or VLDL-C concentrations as compared with control. Albumin concentration was the highest at the MWM inclusion levels of 5.0, 7.5 and 10.0%. At 28 days, triacylglycerols, VLDL-C and LDL-C were the lowestat 7.5% inclusion whereas at 42 days, these same variables were the lowest with addition of 10.0% meal. At 14, 28 and 42 days of age, the VLDL-C, LDL-C and total TAG contents were found to decrease at mango waste meal inclusion levels of 5.0 and 7.5% in the diets, which maybe considered an indicator of improvements in the metabolic conditions of broilers.

“…The antioxidant effect of CA was observed from the beginning of storage (0 days) because the breasts from chickens fed with 7.5 and 10.0 g kg −1 CA had lower lipid oxidation. Freitas et al . also observed that antioxidant already acted at the beginning of storage in the breasts of chickens fed with mango seed extract.…”

BACKGROUND: Anacardic acid, a phenolic compound, represents 90% of cashew nut shell liquid, which is a byproduct from the industrial processing of cashew nuts. This study aimed to add calcium anacardate (CA) to broilers' diets as a source of anacardic acid, to evaluate its antioxidant effect in breast meat and in processed meat products (sausages). For this purpose, birds were fed according to the following treatments: diet without antioxidant and diets containing 2.5, 5.0, 7.5, or 10.0 g kg −1 CA. Chicken breast meat was stored frozen for 90 days. The thigh and drumsticks were used to produce chicken sausages that were kept in refrigerated conditions for 90 days. Lipid oxidation and color stability were assessed every 30 days. RESULTS:For breast meat, a 2.5 g kg −1 concentration of CA was insufficient to retard lipid oxidation, whereas 10.0 g kg −1 gave rise to a pro-oxidant effect and 5.0 g kg −1 slowed the oxidation up to 50 days. A level of 7.5 g kg −1 of CA was effective in retarding oxidation, favoring colour stability during the 90-days frozen storage. For sausages, 2.5 g kg −1 of calcium anacardate in broiler diets was sufficient to retard lipid oxidation. Calcium anacardate 7.5 g kg −1 provided greater redness in the sausages compared with the control and with the other treatments containing 5.0 and 10.0 g kg −1 . CONCLUSIONS: Calcium anacardate is a potential natural antioxidant for breast meat and sausages in storage when added to broilers' diets. RESULTS Lipid oxidation of frozen breast meatFor frozen breast meat, there was an interaction (P ≤ 0.05) between treatments and storage times for TBARS values (Table 2) indicating J Sci Food Agric 2019; 99: 2124-2131 Color of frozen breast meatAn increase in redness during storage was also reported by Kim et al. 22 in the meat of broilers fed with -tocopherol during storage. Most studies reported a reduction in redness and explained that reduction shows discoloration resulting from the oxidation of myoglobin, which is the primary pigment responsible for the meat color. 23,24 The results obtained in this study are therefore satisfactory because there was no meat discoloration during storage.In the present study, the concentration of the CA did not affect redness. Different results were reported by Choi et al. 25 with garlic powder and by Young et al. 26 using oregano extract. These authors observed that natural antioxidants added in the feed increased the redness in meat broilers.According to Zapata et al. 27 the color L* component was one of the main parameters used in the identification of meat abnormalities such as PSE (pale, soft, and exudative) and DFD (dark, firm, and dry) meat. The PSE meat has high lightness values, resulting in J Sci Food Agric 2019; 99: 2124-2131
