چکیده
روغن مورینگا به عتوان یک روغن فراسودمند در صنایع غذایی، دارویی، آرایشی و بهداشتی مورد استفاده قرار می­ گیرد. همچنین تحقیقات گذشته نشان داده است که امواج مایکروویو با متلاشی نمودن ساختار سلولی دانه روغنی، می­توانند به افزایش راندمان استخراج روغن کمک بنمایند. لذا در این تحقیق به منظور بالا بردن راندمان روغن­ گیری دانه مورینگا، از پیش ­تیمار امواج مایکروویو قبل از روغن­ گیری توسط پرس مارپیچی استفاده شده است. در این پژوهش، بهینه­ سازی استخراج مکانیکی این روغن از دانه مورینگا با استفاده از روش سطح پاسخ انجام گرفت. آزمایش­ های روغن ­گیری با پیش­تیمار مایکروویو در مدت زمان­های 2، 3 و 4 دقیقه و توان ­های 200، 400 و 600 وات انجام شد. نتایج آزمایش­ها نشان داد که راندمان استخراج با افزایش مدت زمان اعمال مایکروویو و توان مایکروویو ابتدا افزایش و سپس کاهش یافت. مقدار بهینه راندمان استخراج برابر 56.55 درصد در مدت زمان اعمال مایکروویو 3.02 دقیقه با شدت توان مایکروویو 380.92 وات به دست آمد. با توجه به مقادیر بالای ضریب همبستگی (0.97) می­توان مدل پیش بینی شده را مناسب ارزیابی کرد.

چکیده English

A novel approach for bio-lubricant production from rapeseed oil-based biodiesel using ultrasound irradiation: Multi-objective optimization Moringa oil is used as a useful oil in the food, medicinal, cosmetic and health industries. Also past research has shown that microwaves can increase the extraction efficiency of oil by disintegrating the cellular structure of oil seed. Therefore, in this research, for increasing oil extraction efficiency, microwave pretreatment was used before oil extraction from Moringa seeds by spiral press. In this study, the optimization of oil mechanical extraction from Moringa seeds was done using the Response Surface Methodology. In this study, extraction experiments were done with microwave pretreatment at different level of times (2, 3 and 4 min) and powers (200, 400 and 600 W). The results showed that the extraction efficiency increases and then decreases by increasing microwave time and microwave power. The optimum extraction efficiency was 56.55% during the microwave action time of 3.02 min and the microwave power intensity of 380.92 W. Due to the high values of correlation coefficients (R2 = 0.97) the predicted model for oil extraction efficiency can be evaluated properly.
