| The aim of this study was to estimate and compare some of chemical constituents in nuts and seeds consumed as snacks and available in the local market of Misurata city in Libya. 18 kinds of local and imported raw and roasted nuts and seeds samples were randomly collected from stores distributed across the city, with 3 - 4 replicates of each kind, in order to estimate the concentrations of some chemical components and heavy elements, which were lead (Pb), cadmium (Cd), Iron (Fe), copper (Cu), chromium (Cr), manganese (Mn), cobalt (Co), zinc (Zn), nickel (Ni), moisture, ash, total solids and protein. The dry digestion method was used to prepare the samples for heavy metals determination using Flame Atomic Absorption Spectrometer. Also, moisture, ash and total solids contents were determined, and Kjeldahl method was used to estimate proteins. The results showed that the average concentrations of heavy metals varied significantly with sample kind. The levels of the studied metals were as follows: 0.075 - 1.167, 31.50 - 116.00, 0.325 - 1.325, 9.425- 71.00, 0.025-3.87, 8.325- 24.825, 0.175- 1.250, 0.050- 0.750, 43.00- 98.325 mg/kg, for Co, Zn, Ni, Mn, Pb, Cu, Cr, Cd, and Fe, respectively. Also, levels of moisture contents, ash contents, total solids contents, and protein levels were: 4.0 - 8.5%, 2.0 - 11.39%, 91.5 - 96.0%, and 11.8 - 33.2%, respectively. Most of the obtained results were consistent with the previous studies and within the permissible limits. | ||

| چکیده [English] | ||
| هدف این مطالعه تخمین و بررسی بعضی ترکیبات شیمیایی موجود در دانه ها و مغزهای خوراکی موجود در فروشگاه های محلی شهر میسوراتا در لیبی می باشد. 18 نوع مغز و دانه های خام و برشته بطور تصادفی (از هر نوع 3 تا 4 نمونه) از فروشگاه ها جمع آوری و غلظت بعضی از ترکیبات شیمیایی و عناصر سنگین مثل سرب، کادمیم، آهن، مس، کروم، منگنز، کبالت، روی، نیکل، میزان رطوبت، خاکستر و پروتئین کل دانه ها تعیین گردید. روش هضم خشک برای آماده سازی نمونه ها در تعیین عناصر سنگین با استفاده از جذب اتمی شعله بکار گرفته شد. همچنین، رطوبت، خاکستر و کل مواد جامد تعیین و کجلدال برای اندازه گیری مقدار پروتئین استفاده شد. نتایج نشان داد که غلظت متوسط فلزات سنگین در نمونه های مختلف بطور چشمگیری با یکدیگر متفاوت است. میزان عناصر مطالعه شده به قرار 1.167-0.075، 116.00-31.5، 1.325-0.325، 71.00-9.425، 3.87-0.025، 24.825-8.325، 1.250-0.175، 0.750-0.050، 98.325-43.00 میلی گرم بر کیلوگرم به ترتیب برای عناصر کبالت، روی، نیکل، منگنز، سرب، مس، کروم، کادمیم و آهن بدست آمد. همچنین میزان رطوبت، خاکستر، کل مواد جامد و پروتئین به ترتیب %8.5-4.0، %11.39-2.0، %96.0-91.5 و %33.2-11.8 بدست آمد. اکثر نتایج بدست آمده با مطالعات قبلی سازگار و در حد مجاز می باشد. | ||
