Determination of chemical composition, and storage on dried fermented goat milk product (Oggtt)

A sample of dried fermented goat milk product (oggtt) obtained from the local market of riyadh city in the kingdom of saudi arabia, was stored for 6 months at 4 c and subjected to chemical composition analysis before and after storage. the result showed that the sample moisture increased significantly (p 6≤ 0.05) after storage from 7% to 10%, total ash decreased non-significantly (p≤ 0.05) from 8% to 7.6%, total carbohydrates decreased non-significantly (p≤ 0.05) from 35.5% to 33.8%, protein increased non-significantly (p≤ 0.05) from 16 to 16.1 g/l, fat content was found to have the same values in all samples before and after storage at 5%, lactose increased (p ≤ 0.05) non-significantly from 28.4% to 29%, acidity decreased (p ≤ 0.05) significantly from 0.45% to 0.39%, and ph decreased (p ≤ 0.05) non-significantly from 4.3% to 4%. on the other hand, mineral composition showed (p≤ 0.05) non-significant results before and after storage. ca concentration decreased from 118 to 1149 mg/kg and k concentration increased from 185.8 to 1888 mg/kg. while mg increased from 105 to 123 mg/kg, zn increased from 8.3 to 8.6 mg/kg, mn and fe were found to have the same values of concentrations before and after storage which were 0.2 and 0.1 mg/kg, respectively. accordingly, we can conclude that oggtt is a stable product and have a good nutritional value in comparison to daily required amounts for healthy human life.
