چکیده مقاله :
مقدمه: نانوذرات طلا بدلیل دارا بودن اثرات غیر سمی برای انسان می تواند بعنوان یک ترکیب محافظ در بسته بندی مواد با ارزش غذایی مورد استفاده قرار گیرد. با مرور منابع کاربردهایی دیگری در صنعت غذا از قبیل ساخت حسگرجهت شناسایی باقی مانده مواد خطرناک حاصل از فرآیندهای کشاورزی و صنعتی، برای این مواد متصور است. سنتز سبز این نانوذرات با استفاده از ترکیبات طبیعی به دلیل کاهش اثرات جانبی مواد شیمیایی، رویکردی نوینی است که در سال های اخیر از آن تحت عنوان " شیمی سبز" از آن یاد می گردد.مواد و روش ها: در این مطالعه، نانو ذرات طلا به کمک ترکیب کورکومین خالص شده (بیش از 95%) از ادویه زرد چوبه بعنوان منبع اصلی این ترکیب، سنتز گردید. فرآیند سنتز با کمک روش های طیف سنجی ماوراء بنفش- مرئی و مادون قرمز- تبدیل فوریه مورد بررسی قرار گرفت. ساختار و مورفولوژی نانوذرات با استفاده از طیف سنجی پراش اشعه ایکس و عکسبرداری میکروسکوپی الکترونی عبوری و روبشی صورت پذیرفت. خواص آنتی اکسیدانی نانوذرات طلا- کورکومین با روش تله اندازی رادیکال آزاد DPPH مورد سنجش قرار گرفت.یافته ها: نانوذرات طلا به کمک روش شیمی سبز و با استفاده از کورکومین خالص شده از زرد چوبه در شکل کروی و ساختار کریستالی مکعبی وجوه پر و با ابعاد میانگین 80/9 نانومتر سنتز گردید. مطالعات آنتی اکسیدانی نشان داد که توانایی جذب رادیکال آزاد نانوذرات طلا- کورکومین در قیاس با کورکومین خالص (1/8%) افزایش یافت.نتیجه گیری: کورکومین بعنوان یک ترکیب طبیعی و دارای خواص آنتی اکسیدانی توانایی کاهش یونهای طلا و تبدیل آنها را به نانو ذرات دارا می باشد که با توجه به کاربرد این نانوذرات در صنعت غذا، از این روش می توان بعنوان یک روش سبز، ارزان و سالم استفاده کرد.
Introduction: Gold nanoparticles can be used as a protective compound in the packaging of nutritionally valuable materials due to their non-toxic effects on humans and high antibacterial and antioxidant properties. Other applications in the food industry, such as the construction of sensors to identify the remnants of hazardous materials from agricultural and industrial processes, are conceivable for these materials. One of the methods of synthesis of these nanoparticles is the use of natural compounds due to reducing the side effects of chemicals, a new approach that in recent years has been referred to as "green chemistry".Materials and Methods: gold nanoparticles were synthesized using curcumin purified from turmeric as the main source of this compound. The synthesis process was investigated using UV-VIS, FT-IR spectroscopy methods. The structure and morphology of the nanoparticles were performed using XRD spectroscopy and TEM and SEM imaging. The antioxidant properties of gold-curcumin nanoparticles were evaluated by DPPH free radical scavenging method.Results: Au-nanoparticles were synthesized using the green chemistry method using curcumin purified from turmeric in the form of a cross and cubic crystal structure of filled funds with an average size of 9.80 nm. Antioxidant studies showed that the free radical scavenging ability of gold-curcumin nanoparticles was increased as compared to pure curcumin.Conclusion: Curcumin as a natural compound with antioxidant properties has the ability to reduce gold ions and convert them into nanoparticles, and due to the use of these nanoparticles in the food industry, this method can be used as a green, inexpensive and eco-friendly.
