Chemical Composition and Fatty Acids Profile of Camels Milk in Middle Darfur State

Abstract

The present study was carried out in Middle Darfur state, during the period from July to August - 2014. The aims of this study were to determine the chemical composition and fatty acids profile of camel milk from four different areas in Middle Darfur state. Forty camel's milk samples were obtained from four different areas in Middle Dar Fur state; Garsilla, Nertety, Abata and Sullo, ten samples from each area. The collected milk samples were analyzed for chemical composition and fatty acids profiles. The obtained data were statistically analyzed using ANOVA and Least significant different (LSD) for mean separation of the chemical composition and fatty acids of camel milk between four areas. The results presented that the total solids contents was significantly difference (P <0.05). While no significant variations (P >0.05) were found in protein, fat, titratable acidity, ash contents and specific gravity of the camel milk samples in the four areas. The highest values of milk protein contents were recorded in Sullo and Abata areas (3.64±0.18% and 3.64±0.14%, respectively), while the highest value of fat contents were recorded in Garsilla area (3.81±0.29%). Garsilla, Abata and Sullo areas were recorded highest values of acidity (0.14±0.01%), while the highest values of ash contents were recorded in Garsilla area (0.95±0.17%). Specific gravity of the milk samples in all areas were recorded the same value (1.029±0.01). The results showed that significant variations (P <0.05) were found in ecosenoic and heptadecenoic fatty acids profile of the camel milk in the four areas. While no significant differences (p> 0.05) were reported in capric, lauric, tridecanoic, myristoloic, oleic, caprylic, palmitoleic, stearic, arachidic, eicosadenoic, palmitic, linoliec, linolenic, erucic, tricocenoic, nervonic and behenic acids of the camel milk samples. Capric and myristoloic acids were found in samples collected from Garsilla, Nertety and Sullo areas, while were not detected in Abata area samples. lauric, oleic, caprylic and palmitoleic acids were found in all samples collected from Garsilla, Nertety, Abata and Sullo. Tridecanoic acid was found only in samples of Garsilla area.Eicosenoic and heptadecenoic acids were found in samples of Garsilla, Abata and Sullo areas except samples of Nertety area. Also stearic acid was found in samples of Nertety, Abata and Sullo except samples of Garsilla area. However, arachidic, eicosadenoic, palmitic and linolenic were not detected in samples of Garsilla and Nertety areas. Linoliec, erucic, tricocenoic and nervonic acids were found only in samples of Abata area. While behenic acid was found only in Sullo area samples.
