Yağsız Pirinç Kepeğinin Çözünür, Çözünmez ve Toplam Diyet Lifi İçeriği Üzerine Yüksek Basınç, Otoklavlama ve Ekstrüzyon İşlemlerinin Etkisi

Bu çalışmada yağından arındırılmış pirinç kepeğinin çözünür, çözünmez ve toplam diyet lifi içeriği ile genel bileşimi üzerine yüksek basınç, otoklavlama ve ekstrüzyon işlemlerinin etkisi araştırılmıştır. Yağsız pirinç kepeği 300, 400 ve 500 MPa basınca 5, 10 veya 15 dakika, 122°C veya 136°C sıcaklıkta otoklavalama işlemine bir saat ve 100 veya 140 d/d'lık vida hızında ekstrüzyon işlemine maruz bırakılmıştır. Basınç 300'den 400 MPa'a çıkarıldığında çözünmez lif içeriği (10 dakikalık işlemde %28.62'den %32.09'a) önemli bir oranda artmıştır (p

Effect of High Pressure, Autoclaving and Extrusion Treatments on Insoluble, Soluble and Total Dietary Fiber Contents of Defatted Rice Bran

In this study, the effects of high pressure, autoclaving and extrusion treatments on the insoluble and soluble contents and compositions of defatted rice bran were investigated. The defatted rice bran was subjected to high pressure (300, 400 and 500 MPa) for 5, 10 or 15 min, autoclaved at 122 or 136°C for 1 h and extruded with a screw speed at 100 or 140 rpm. Insoluble fiber content significantly (p
