چکیده

نیم‌جوش کردن یا پاربویل کردن مخلوطی از تیمار آبی و حرارتی بر شلتوک و شامل سه مرحلۀ اصلی است: خیساندن در آب، حرارت‌دهی با بخار و خشک کردن.  مهم­ترین هدف پاربویل کردن کاهش درصد شکستگی برنج است، هرچند ارزش غذایی آن نیز افزایش می‌یابد.  در این پروژه سه رقم برنج: طارم محلی، شیرودی و فجر تحت تیمار پاربویل شده قرار داده شدند و فاکتورهای تبدیل و کیفیت بین دو حالت پاربویل شدن و پاربویل نشدن مقایسه شدند.  مهمترین تغییرات پس از پاربویل شدن کاهش معنی‌دار درصد خرده برنج در دو رقم شیرودی و فجر، کاهش سفیدی ارقام، تغییر در خصوصیات پخت و از جمله کاهش مواد جامد از دست رفته و افزایش سختی ارقام پاربویل شده است.

Effect of Parboiling on Qualities and Milling of Iranian Rice

چکیده [English]

Parboiling of paddy rice is a three-step hydrothermal process consisting of soaking, heating and drying. Parboiling decreases the percentage of broken rice and increases the nutritional value of the rice. The present study examined the Tarom, Shirody and Fajr rice varieties. The rice was parboiled, then milled and the variables for parboiled and non-parboiled rice were recorded. The most significant change was the decrease in broken rice in the Shirody and Fajr varieties, and a decrease in whiteness and solids and an increase in hardness in all parboiled rice varieties.
