- Cashew nuts (Anacardium occidentale L.) decrease visceral fat, yet augment glucose in dyslipidemic ratsPublication . Dias, Celina C. Q.; Madruga, Marta S.; Pintado, Maria Manuela E.; Almeida, Gabriel Henrique Oliveira; Alves, Ana Paula Vilar; Dantas, Francileide Amaro; Bezerra, Jéssyka Kallyne Galvão; Melo, Marília Ferreira Frazão Tavares de; Viera, Vanessa Bordin; Soares, Juliana Késsia B.The objective of this study was to evaluate the biological effects of roasted Cashew nuts consumption on biochemical and murinometric parameters in dyslipidemic rats receiving lipid supplementation. Young male rats were randomly assigned to three experimental groups (n = 10). The Control group (CONT) was treated with water, the Dyslipidemic group (DL) received a high fat content emulsion throughout the experiment, and the Dyslipidemic Cashew Nuts group (DLCN) received the same high fat content emulsion throughout the experiment, yet was treated with Cashew nuts. Body parameters, biochemical, hepatic and fecal fatty acid profiles were all evaluated. The levels of total cholesterol and triglycerides were higher in the DL and DLCN groups as compared to the control group. DLCN and CONT presented no difference in HDL levels. DLCN presented higher glycemia levels than the other groups. There was reduction of body fat in DLCN as compared to other groups, but with higher accumulations of liver fat. DLCN presented a reduction in saturated hepatic fatty acids of 20.8%, and an increase of 177% in relation to CONT; there was also a 21% in increase DL for ω9 fatty acids in comparison to CONT. As for fecal fatty acids, there was a lower concentration of polysaturates in DLCN as compared to the other groups. The data showed that the consumption of Cashew nuts by the dyslipidemic animals treated with a hyperlipidic diet induced greater accumulations of liver fat and worsened glycemic levels, despite having reduced visceral fats and increased fecal fat excretion.
- Maternal supplementation with avocado (persea americana mill.) pulp and oil alters reflex maturation, physical development, and offspring memory in ratsPublication . Melo, Marilia Ferreira Frazão Tavares de; Pereira, Diego Elias; Moura, Renally de Lima; Silva, Elisiane Beatriz da; Melo, Flávio Augusto Lyra Tavares de; Dias, Celina de Castro Querino; Silva, Maciel da Costa Alves; Oliveira, Maria Elieidy Gomes de; Viera, Vanessa Bordin; Pintado, Maria Manuela Estevez; Santos, Sócrates Golzio dos; Soares, Juliana Késsia BarbosaAvocado (Persea americana Mill.) is an oleaginous fruit source of fatty acids with high levels of neuroprotective phytocomplexes. The objective of this study was to evaluate the development of reflex and somatic maturation, fatty acid profiles in the brain, and memory in different stages of life in the offspring of dams supplemented with avocado pulp and oil during gestation and lactation. The dams were randomly divided into three groups (n = 15 pups/group), and recieved by gavage supplementation: control group (CG)-distilled water; Avocado Oil (AO)-3,000 mg avocado oil/kg animal weight, and Avocado Pulp (AP)-3,000 mg avocado pulp/kg animal weight. We performed the following tests: Analysis of Somatic Development and Ontogeny of Postnatal Reflex (T0 to T21), the Open Field Habituation Test and the Object Recognition Test (ORT) in the adolescent (T45) and adult (190) phases. The cerebral fatty acids content was evaluated at times T0, T21, T45, and T90. The results were analyzed using the statistical program GraphPad Prism and significant statistics were considered when p < 0.05. Acceleration of reflex maturation and reflex ontogeny was observed in the offspring of AO and AP fed dams, with the results being more pronounced in the pulp fed group (p < 0.05). All groups presented a decrease in the ambulation parameter in the second exposure to the Open Field Habituation Test, at T45 and 190 (p < 0.05). In the ORT, the AO and AP offspring presented memory improvements in the short and long term in the adult and adolescent phases (p < 0.05). The results of the brain fatty acid profiles presented higher polyunsaturated fatty acids (PUFA) content in the AO and AP groups at T21, T45, and 190. The docosahexaenoic fatty acid (DHA) content was higher at T21 (AO and AP), at T45 (AO and AP), and at T90 (AP) (p < 0.05). The arachidonic acid (ARA) content was higher at T45 (AO and AP), and at T90 (AO) (p < 0.05). Maternal supplementation with avocado oil and pulp anticipates reflex maturation and somatic postnatal development, and improves memory during the adolescent and adult phases.
- Low fat goat meat sausage with chitosan-glucose Maillard reaction product: impact on quality and shelf lifePublication . Amaral, Deborah Silva do; Cardelle-Cobas, Alejandra; Dias, Celina de Castro Querino; Lima, Darlinne Amanda Soares; Pereira, Sérgio de Ferreira; Arcanjo, Naciza Maria de Oliveira; Dalmás, Paulo Sérgio; Madruga, Marta Suely; Pintado, Maria Manuela EstevezLow fat fresh goat sausages based on chitosan (LMWC) and derivative chitosan (LMWC-Glc) were developed aiming to produce a functional food product evaluating the effect of inclusion of these compounds on quality, stability and shelf life. Goat sausages (10% pork fat) were formulated with 2% (w/w) of LMWC or LMWC-Glc and stored at 4 °C during 21 days. Results indicated that incorporation of LMWC-Glc and LMWC is technologically feasible, originating a potential functional product with low fat content, besides the positive impact on microbial safety. The modified LMWC (towards better solubility and lower adstringency) incorporated at 2% as functional ingredient maintained positive effect on antimicrobial, nutrional, textural and sensory performance. The results also proved that derivative chitosan may also be a promising strategy for improving the quality and extending the shelf life of low fat goat sausage.
