ملخص المقالة :
دوغ یک نوشیدنی تخمیری شیری است که زمان ماندگاری آن می تواند در اثر فعالیت ﻣﯿﮑﺮوارﮔﺎﻧﯿﺴﻢﻫﺎ و تغییرات شیمیایی و حسی در ﻣﺤﺼﻮل کاهش یابد. این مطالعه با هدف تولید دوغ گرمادیده با استفاده از عصاره‌های شوید (05/0، 075/0 و 1/0 درصد) و سیر (04/0، 06/0 و 08/0 درصد) به‌صورت ترکیبی و به‌عنوان نگهدارنده طبیعی انجام گرفت. ویژگی‌های میکروبی، شیمیایی و حسی نمونه ها در طول 6 هفته نگهداری در دمای 8 درجه سلسیوس ارزیابی شدند. نتایج نشان داد که شمارش میکروبی وابسته به سطح عصاره‌های مورد استفاده در فرمولاسیون نمونه‌های دوغ بود، به‌عبارت دیگر، افزایش سطح عصاره‌ها به‌طور معنی‌داری شمارش کلی باکتریایی و شمارش کپک و مخمر را در محصول کاهش داد (05/0>p). هم‌چنین نتایج نشان داد با افزایش زمان نگهداری نمونه‌های دوغ به طور معنی داری میزان pH کاهش و میزان اسیدیته افزایش یافت اما میزان این تغییرات در تیمارهای حاوی غلظت‌های مختلف عصاره‌های سیر و شوید در مقایسه با شاهد از شدت کمتری برخوردار بود (05/0>p). هم‌چنین افزایش سطح عصاره‌ها در تیمارها امتیاز اغلب ویژگی های حسی (طعم، بو، احساس دهانی و پذیرش کلی) را افزایش داد (05/0>p). در طول مدت زمان نگهداری، نمونه شاهد عمدتاً دارای کم‌ترین امتیازات خصوصیات حسی (به‌استثناء رنگ) و بیش‌ترین بار میکروبی و اسیدیته بود و با اکثر تیمارها اختلاف آماری معنی داری داشت (05/0>p). با توجه به نتایج کسب شده، نمونه دوغ حاوی ترکیب 1/0 درصد عصاره شوید و 08/0 درصد عصاره سیر به‌عنوان تیمار برتر معرفی گردید.
