Assessment of Physicochemical Properties and Mineral Compositions of Almond (Prunus amygdalus) Gum of Libyan Origin

Twenty-five authentic samples of Prunus amygdalus gum samples were collected from five different locations in northwest of Libya. Different physicochemical methods were used to characterize this type of gum samples. The mean values of the moisture ranged from 12.55 to 14.93%, ash mean values 4.03 to 4.62%, pH 3.89 to 4.40, W.H.C 52.85 to 60.0%, and O.H.C 136.2 to 156.3%. Solubility of Prunus amygdalus gum showed that it had low solubility in distilled water with the mean values ranged from 20.01 to 35.40%, but it dissolved perfectly in alkali media where solubility increased to 96.3% in 0.05 M Na2CO3. The study exhibited that the mean values of cationic concentration in %(w/w) such as calcium was ranged from 0.552 to 0.585, potassium 0.402 to 0.505, iron 0.0975 to 0.1125, and sodium 0.064 to 0.079, which indicates that Ca has the highest concentration of metallic ions present. Atomic absorption method indicate that all samples contain traces of elements, Li, Cr, Mn, Ni, Zn, Pb, Hg, and Cd. The main functional groups recorded from FTIR spectrum included bands at 3293 cm-1 (O-H in carboxylic group), 1601.77 cm-1 (C=O, amide N-H bend, and C=C), 1357.53 cm-1 (CH3-, and C-O-H in- plane bending vibration), and 1025.74 cm-1 (C-O stretching). arabic 16 English 99

Determination of Some Trace Elements in Different Vinegar Samples from Libyan Market using Inductively Coupled Plasma Atomic Emission Spectrometer ICP-AES

Ten vinegar samples were collected from the Libyan local market in the city of Tripoli. The elements have been investigated were:As, Pb, Cu, Fe and Zn. The samples were treated and prepared according to Indian standard IS 14703-1999, and the measurements have been done by using inductively coupled plasm – atomic emission spectroscopy (ICP-AES) available in the Libyan Petroleum Institute. The analysis indicated that the concentration of Arsenic of all the samples was less than 0.02mg/kg whereas, the concentration of lead is less than 0.03mg/kg. The concentration ranges of Cu, Fe and Zn were 0.11-0.59mg/kg, 0.72-2.67mg/kg and 0.08-0.28mg/kg respectively. The concentrations of the elements AS, Pb, Cu, Fe and Zn are within the limits of a variety of standards such as Libyan, Indian and Pakistani ones. arabic 21 English 134
