The Abstract

Dear valuable readers,

Just done my last editing session of my last minute abstract for my thesis, before I want to submit it to my SV this afternoon.

Kinda busy with lot of things, cramping my muscles into something that not my muscle. (dah, mula merepek dah)

Btw, just see through and compare these two abstracts- one in English and one in BM.

Spot the differences, similarities and anything that you can discuss regarding this matter.

I will discuss and give some insights later.

Thank you.

Abstract

The use of membrane separations using ultrafiltration (UF) in the fractionation of soy protein from soy milk has generated considerable interest, recently. Compared to traditional methods, UF gives higher yield and superior functional properties of the soy protein, and also allows the recovery of active soybean trypsin inhibitor (STI) for medical purposes. The performance of the ultrafiltration (UF) membrane; in term of permeate flux, concentration of protein transmitted and retention ratio, by manipulating transmembrane pressure (TMP) to fractionate soy protein from soy milk is studied. Commercial soy milk samples have been centrifuged and introduced to the ultrafiltration system at various TMP value. Data from permeate flux, concentration of protein transmitted and retention ratio have been manipulated to get the performance of the ultrafiltration membrane. Based on the results, the range of effective TMP to fractionate soy protein from soy milk is between 15 to 20 psi. In this TMP range, the permeate flux is between 25 and 30 LMH, the concentration of protein transmitted is acceptable; between 1.38 and 2. 85 mg/mL and the retention ratio is 90%.

Abstrak

Proses pemisahan membran menggunakan ultraturasan (UF) dalam memisahkan protein soya dari susu soya semakin mendapat perhatian lewat kebelakangan ini. Berbanding dengan cara tradisional, UF memberikan hasil yang banyak dan ciri berfungsi protein soya yang tinggi, di samping membenarkan perencat tripsin kacang soya untuk dikumpulkan. Prestasi membran ultraturasan dengan memanipulasikan tekanan antara membran (TMP) untuk memisahkan protein soya dari susu soya melalui fluks; kepekatan protein menembusi membran, dan nisbah penolakan membran, adalah dikaji. Susu soya komersil yang telah diempar diperkenalkan dengan sistem ultraturasan pada nilai TMP yang pelbagai. Maklumat dari fluks; kepekatan protein menembusi membran, dan nisbah penolakan membran telah dimanipulasikan untuk mendapatkan gambaran mengenai prestasi membran ultraturasan. Berdasarkan keputusan, julat efektif TMP adalah antara 15 dan 20 psi. Dalam julat tersebut, nilai fluks adalah antara 25 dan 30 LMH, kepekatan protein menembusi membran adalah antara 1.38 dan 2.85 mg/mL dan nisbah penolakan membran adalah 90%.

Keywords: ultrafiltration (UF), transmembrane pressure (TMP), soy protein, soy milk

p.s - u free to correct me if anything wrong in grammar or tatabahasa. beta pon bukannya pandai sangat berbahasa! =p
