| چکیده | ||
| هدف از این تحقیق تهیه امولسیونی فوق پایدار برای کانتازانتین با نانوکریستال سلولز و بررسی صفات فیزیکوشیمیایی آن بود. کانتازانتین استفاده شده در این تحقیق متابولیت باکتری Dietzia natronolimnaea HS-1 بود. نانوذرات سلولز از الیاف کتان با روش هیدرولیز اسیدی تهیه گردید. نتایج پراکندگی نور دینامیک، میکروسکوپ نیروی اتمی نشان داد که طول ذرات 11±112 و قطر 2±5 نانومتر بود. بلورینگی ذرات پس از هیدرولیز از 4/76 برای الیاف کتان به 6/86 درصد رسید. نتایج آزمون اسپکتروسکوپی فوریه (ATR) نشان داد گروه های هیدروکسیل سطحی نانوکریستال نسبت به سلولز بیشتر بوده و هضم کامل همی سلولز توسط اسید صورت گرفت. امولسیونهای پیکرینگ روغن در آب با استفاده از هموژنایزر اولتراسونیک تهیه شدند. نتایج آزمونهای ریخت شناسی بیانگر نمونهای با پراکندگی ذرات یکسان بود. امولسیونها در شرایط محیطی پایداری بسیار خوبی از خود برای مدت زمان طولانی نشان دادند. | ||

| چکیده [English] | ||
| The aim of this study was to prepare an ultra-stable emulsion for canthaxanthin with cellulose nanocrystals and investigating its physiochemical properties. Canthaxanthin used in this study was a metabolite of Dietzia natronolimnaea HS-1. Cellulosic nanocrystals (CNCs) of cotton linter were made and characterized using acid hydrolysis. Dynamic light scattering (DLS) alongside Atomic Force Microscopy (AFM) represented needle-like particles with length of 212±11 and thickness of 5±2. The crystallinity degree of CNC for cotton linter increased from (76.4%) to (86.6%). FTIR (ATR) spectroscopy suggested more surface hydroxyl groups for CNCs than native cellulose and complete digestion of hemicelluloses by acid. Pickering emulsions of oil in water were prepared using an ultrasonic homogenizer. The results of the morphological tests indicated a sample with the same particle dispersion. Results indicated that generated emulsions represent promising stability in different environmental conditions for a long period of time. | ||
