Perubahan mutu protein daging ayam broiler akibat proses pengolahan

Abstract

This research was conducted to compare the effect of many processing technology in protein quality of chicken meat broiler and also the other products (meat ball, sausage, abon, dendeng and roast meat). The meat from the chicken breast was purchased and then divided evenly into three parts. One pal? represented "fresh meat" and the other parts were processed to make meat ball, sausage, dendeng, abon and roast meat. Chemical analysis was conducted to assess crude protein content of the fresh meat, meat ball, sausage, dendeng, abon and roast meat. In vitro analysis was also conducted to measure the protein digestibility of these groups of samples. The SDS-PAGE (Sodium of Deodecyl Sulphate-Polyacrylamide of Gel Electrophoresis) was used to measure weight of molecule protein samples. The data were observed descriptively. The results indicated that the protein content (on wet basis) of fresh meat, meat ball, sausage, abon, dendeng and roast meat were 22,11%; 14,88%; 15,39%; 37,05%; 26,62% and 36,14% respectively. The protein content (on dry matter basis) of fresh meat, meat ball, sausage, abon, dendeng and roast meat were 91,03%; 54,18%; 43,85%; 38,49%; 39,53% and 78,30%. The protein digestibility of fresh meat, meat ball, sausage, abon, dendeng and roast meat were 90,71%; 82,33%; 86,51%; 73,84%; 71,35% dan 77,88% respectively. The total number of protein ribbon of fresh meat, meat ball, sausage, abon, dendeng and roast meat were 23, 11, 9, 6, 14 and 6 protein ribbon. The data showed that the crude protein of abon relatively higher than derivated meat products. The protein digestibility values was sausage relatively higher than derivated meat products and the digested protein was roast meat relatively higher than derivated meat products. The highest number of protein ribbon which were detected by derivated meat chicken broiler in dendeng.
