چکیده

در این تحقیق تأثیر‏ پیش­تیمارهای قبل از سرخ کردن (بلانچینگ در آب 85 درجة سلسیوس حاوی 5/0درصد کلریدکلسیم به مدت 6 دقیقه و سپس فرو بردن در محلول 1 درصد کربوکسی­متیل­سلولز، بلانچینگ در آب 85 درجة سلسیوس حاوی 5/0 درصد کلریدکلسیم به مدت 6 دقیقه و سپس فرو بردن در محلول 2 درصد ثعلب و تیمار شاهد) و همچنین تأثیر‏ نوع روغن (روغن کانولا، روغن کانولا حاوی 1/0 درصد روغن مغز بنه (BKO))، روغن کانولا حاوی 100 پی­پی­ام آنتی­اکسیدان سنتزی ترسیوبوتیل­هیدروکینون (TBHQ)، و روغن کانولا حاوی 100 پی­پی­ام مواد صابونی­­ناشوندة روغن مغز بنه (UFB) بر سینتیک دفع رطوبت و جذب روغن خلال سیب­زمینی طی فرآیند سرخ کردن عمیق مطالعه شد.  نتایج نشان می­دهد که میزان دفع رطوبت و جذب روغن با افزایش زمان سرخ کردن افزایش می­یابد (ضریب تبیین بیش از 91/0).  روغن حاوی ترکیبات آنتی­اکسیدانی باعث کاهش دفع رطوبت و جذب روغن می­شود و کارآیی روغن مغز بنه و مواد صابونی­­ناشوندة آن معادل کارآیی آنتی­اکسیدان سنتزی قدرتمند ترسیوبوتیل­هیدروکینون است.  پیش­تیمارهای قبل از فرآیند باعث کاهش دفع رطوبت و جذب روغن می­شوند و کارآیی صمغ کربوکسی­متیل­سلولز نسبت به ورود روغن و خروج رطوبت از کارآیی صمغ ثعلب بیشتر است.

Effect of Bene Kernel Oil and Its Unsaponifiable Matter Fraction and Salep Hydrocolloid during Deep Fat Frying on Kinetic Oil Uptake by Potato Strips

چکیده [English]

This study examined the influence of pre-frying treatments and oil type on the moisture outflow and oil uptake during the frying of potato strips. The pre-treatments were 6 min blanching in a 85°C a water bath containing 0.5% calcium chloride and immersion in a 1% solution of carboxymethyl cellulose; 6 min blanching in a 85°C water bath containing 0.5% calcium chloride and immersion in a 2% solution of salep; and the control condition. The type of oil used was CAO containing 0.1% bene kernel oil (BKO), 100 ppm unsaponifiable matter fraction of BKO and 100 ppm tert-butylhydroquinone (TBHQ). The potato strips were fried for 7 min. The results showed that the antioxidative additives and pre-frying treatments decreased moisture loss and oil absorption (R2 > 0.91). The ability of the UFB and BKO to decrease oil uptake was similar to that for TBHQ. The carboxymethyl cellulose decreased oil uptake better than did the salep.
