چکیده

در این پژوهش از تکنیک‏های ماشین بینایی به‌منظور بررسی اثر پیش‏فرآیند مایکروویو بر ویژگی‏های ظاهری دونات استفاده شد. آزمایش‌ها بر اساس روش سطح پاسخ با یک طرح باکس-بنکن طراحی شد. متغیرهای مستقل شامل توان مایکروویو (900-300 وات)، مدت‌زمان پیش‏ فرآیند مایکروویو (90-30 ثانیه) و مدت‌زمان سرخ کردن (130-70 ثانیه) بود. همچنین متغیرهای وابسته شامل ویژگی‏های بافت سطحی، شاخص‏های رنگ پوسته، ویژگی‏های ساختار مغز و پذیرش مصرف ‏کننده بود. نتایج نشان داد افزایش سطح توان مایکروویو، مدت‌زمان پیش‏فرآیند مایکروویو و مدت‌زمان سرخ کردن سبب افزایش قابل‌توجه زبری سطح نمونه‏ ها شد. نتایج همچنین نشان داد اثرات مثبت خطی همه متغیرهای مستقل و اثر منفی درجه دوم توان مایکروویو بر ویژگی‏های ساختار مغز دونات معنی‏دار بود. در مورد رنگ نمونه ‏ها، نتایج نشان داد که شاخص‏های L*و a* سطح نمونه‏ ها با افزایش سطح مدت‏زمان سرخ کردن به‌ترتیب به‌طور قابل‌توجهی کاهش و افزایش یافتند. نتایج حاصل از پذیرش مصرف‏کننده حاکی از تأثیر قابل‌توجه مدت‌زمان سرخ کردن بر نمرات حسی بود. همچنین نتایج حاصل از آنالیز همبستگی نشان‌دهنده وجود ارتباط خطی قوی بین ویژگی‏های ظاهری و خصوصیات حسی دونات بود.
