Potentials of moringa (Moringa oleifera) seed oil in enhancing the nutritional quality and stability of soybean oil

Partial hydrogenation method has been used to improve the stability of soybean oil, though it results in the production of trans-fatty acid. The objective of this study was to establish the potential of moringa oil to improve the stability and nutritional quality of soybean oil. Oil samples were extracted from sundried soybean and Moringa seeds using Soxhlet extraction techniques. Soybean powder was mixed with Moringa powder at ratio 50:50 and 70:30, and the oil was extracted afterward. The fatty acid profile of the extracted oil from these blends was studied using Gas Chromatography-Mass Spectrophotometry (GC-MS) technique. The results showed that commercial soybean oil and the blended soybean/moringa oil of ratio 50:50 and 70:30 had a polyunsaturated fatty acid of 52.70%, 22.18% and 35.73 % respectively; monounsaturated fatty acid 27.22%, 46.61% and 58.79% respectively; saturated fatty acid 19.01%, 19.02% and 17.86% respectively. Also, trans-fatty acid (0.003-0.395%) was obtained in the commercial soybean oil sample. The blended soybean/moringa oil offers a better option than the use of partially hydrogenation in commercial soybean oil.

Digestibilidade in vitro da matéria seca, nitrogênio e fibra em detergente ácido de dietas completas contendo farelo de algodão, uréia ou amiréia In vitro disappearance of dry matter, nitrogen and acid detergent fiber of diets containing cottonseed meal, urea or starea

Este trabalho foi desenvolvido com o objetivo de avaliar o efeito da suplementação com farelo de algodão, uréia ou amiréia a dietas com silagem de milho e milho moído, por intermédio do método da digestibilidade in vitro da matéria seca, nitrogênio e fibra em detergente ácido. O tratamento com uréia apresentou resultados superiores ao demais tratamentos, em todas características estudadas, e os tratamentos com farelo de algodão ou amiréia, resultados semelhantes. Os valores digestibilidade in vitro obtidos foram: 70,5; 69,8 e 72,7% para matéria seca; 61,6; 63,1 e 66,7% para nitrogênio e 30,8; 30,0 e 43,1% para fibra em detergente ácido dos tratamentos contendo farelo de algodão, amiréia e uréia, respectivamente. As dietas com silagem de milho e milho moído suplementadas com uréia fornecem bons resultados de digestibilidade in vitro de matéria seca, nitrogênio e fibra em detergente ácido<br>This work was carried out to evaluate the effect of cottonseed meal, urea or starea supplementation to corn silage and ground corn based diets by In vitro disappearance of dry matter, nitrogen and acid detergent fiber method. The treatment with urea presented better results than the other treatments in all studied characteristics, and the treatments with cottonseed meal or starea presented similar results. The observed In vitro disappearance values were: 70.5, 69.8 and 72.7% for dry matter, 61.6, 63.1 and 66.7% for nitrogen and 30.8, 30.0 and 43.1% for acid detergent fiber for the treatments with cottonseed meal, starea and urea, respectively. The corn silage and ground corn diets supplemented with urea showed good in vitro disappearance of dry matter, nitrogen and acid detergent fiber results
