Abstract
Plasma proteins were obtained from bloods of slaughtered bovine and porcine and analyzed by Fast Protein Liquid Chromatography (FPLC). Serum albumin content decreased in the following order: Porcine Plasma Protein (PPP)> Bovine Plasma Protein (BPP)> Whey Protein Concentrate (WPC). Protein contents of BPP, PPP, and WPC determined by Kjeldahl method were 85.79%, 82.30%, and 84.38%, respectively. Compared to WPC, plasma proteins had higher emulsifying activity index (EAI) below 2% protein concentration and slightly lower EAI above 4% protein concentration. Plasma proteins had higher EAI in the acidic pH range and more dependence on NaCl than WPC. Also, EAI of plasma proteins with NaCl was higher in the acidic range than that of WPC. These results indicated that plasma protein can be utilized as a raw material for emulsifier.
소와 돼지 혈액중의 혈장 단백질을 분리하여, 성분 분석과 단백질 함량을 정량했으며 혈장단백질의 식품 기능성에 관하여서는 기존 유화제로서 활용되는 유청 단백질인 WPC와 비교하여 유화능력을 비교 검토하였다. FPLC 및 SDS-PAGE에 의한 성분분석 결과 혈장 알부민(SA)은 돈혈장단백질(PPP), 우혈장단백질(BPP), 유장단백질(WPC)의 순서로 많이 함유되었으며, 혈장 단백질에는
