Abstract :

هدف از این مطالعه تعیین اثر پرتوتابی تفاله هسته انار بر ترکیب شیمیایی، قابلیت هضم و کینتیک تولید گاز حاصل از آن بود. تفاله هسته انار در معرض پرتوهای گاما و الکترون در دزهای 5، 10، 15 و 20 کیلوگری قرار گرفتند. تعداد 3 رأس قوچ سنجابی برای جمع‪آوری مایع شکمبه در آزمایشات قابلیت هضم و تولید گاز درون آزمایشگاهی استفاده گردید. پرتوتابی اثری بر ترکیب شیمیایی تفاله هسته انار نداشت. پرتوتابی الکترون در مقایسات اورتوگونال اثر معنی‪داری بر فیبر نامحلول در شوینده خنثی نداشت، اما تفاله هسته انار پرتوتابی شده با اشعه گاما در دزهای پایین (یعنی در دزهای 5 و 15 کیلوگری) باعث افزایش فیبر نامحلول در شوینده خنثی گردید (05/0P<). پرتوتابی محتوای تانن متراکم تفاله انار را در تمامی دزها کاهش داد (01/0P<). پتانسیل تولید گاز (b) و نرخ تولید گاز (c) تفاله هسته انار کاهش یافت، اما پرتو الکترون در دزهای 5 و 20 کیلوگری اثری بر پتانسیل تولید گاز تفاله هسته انار نداشت. تیمارهای پرتوتابی اثری بر فاکتور تفکیک کننده نداشت. پرتوهای یونیزه کننده قابلیت هضم تفاله هسته انار را کاهش داد، اما پرتو الکترون در دز 20 کیلوگری و 5، 15 و 20 کیلوگری قابلیت هضم ماده خشک و قابلیت هضم ماده آلی را تغییر نداد. در نهایت نتایج این مطالعه نشان داد که فرآیند کردن با پرتوهای یونیزه کننده، به خصوص پرتوتابی با پرتو الکترون، می‪تواند به عنوان یک روش مطلوب در کاهش تانن متراکم تفاله هسته انار مورد توجه قرار گیرد.
