Publisher : Widya Mandala Surabaya Catholic University

Transglutaminase (TG-ase EC 2.3.2.12) adalah enzim transferase yang memiliki aktivitas mengkatalisa pembentukan ikatan silang antar molekul protein (pembentukan polimer antar molekul protein). Pembentukan polimer antar molekul protein tersebut dijelaskan melalui berbagai hasil penelitian dan ternyata polimer yang terbentuk memiliki sifat fungsional yang berbeda dari protein aslinya (protein yang tidak dipolimerisasi). Perubahan sifat fungsional yang terjadi diantaranya adalah sifat pembuihan, pembentukan gel protein, kelarutan, peningkatan elastisitas adonan dan peningkatan stabilitas protein terhadap panas. Berdasarkan hasil-hasil penelitian yang telah dilakukan, TG-ase memiliki potensi yang besar untuk diaplikasikan pada pangan diantaranya untuk meningkatkan mutu protein pangan melalui pengikatan asam amino esensial pada protein berkualitas rendah, memperbaiki sifat edible film, memperbaiki sifat pembuihan protein, memperbaiki mutu pangan berbasis gel, dapat dimanfaatkan sebagai bahan dalam pembuatan roti dan dapat digunakan untuk meningkatkan stabilitas penyimpanan produk pangan kering. Masalah utama yang dihadapi adalah bagaimana memproduksi TG-ase secara efisien karena TG-ase kebanyakan terdapat pada organ dan cairan tubuh hewan, dimana produksi enzim menggunakan hewan sangat tidak efisien. Saat ini telah ditemukan beberapa species mikrobia yang mampu memproduksi TG-ase, meskipun belum digunakan untuk produksi pada skala komersial.

Sausage is chopped and seasoned meat product with high nutritional value. Sausage was usually made of animal fat, but many people prefer to avoid too much animal fat consumption. This present research, beef sausage was made of corn oil (it was called low fat beef sausage. The aim of the research was to determine the effect of the substitution of wheat flour with maize on the physichochemical and sensory properties and to find the best proportion of wheat flour substitution. Block Randomized Design with single factor, i.e. the proportion of wheat flour and maize (3%: 0; 2,5%:0,5%; 2%:1%; 1,5%:1,5%; 1%:2%; 0,5%:2,5%; 0:3%) was used. The result of this research showed that wheat flour substitution with maize increased moisture and fat content, but decreased the protein content of the sausage. The substitution also increased juiciness, compactness, hardness and cohesiveness of the low fat beef sausage. Substitution of wheat flour at the proportion of wheat flour and maize 1.5%:1.5% resulted in the best properties of low fat beef sausage.

Salmonella is a group of infective pathogenic bacteria for human being that cause many food borne disease outbreaks. Human, animal and some animal-based food products are whicle for Salmonella. Public transportation i.e. train/railway, often serve foods that potentially contaminated with Salmonella. Study on Salmonella detection on fried rice served in economic class train restaurant is necessary for controlling its safety and quality. Standard method was used to detect Salmonella on fried rice including isolation on 2 (two) different selective media, i.e. Bismuth Sulphite Agar and Salmonella-Shigella Agar media (macroscopic and microscopic study) and Biochemical test i.e. sugar and IMVIC test. This study showed that twenty three (23) colonies which, have been found of 8 (eight) samples of fried rice were identified as Salmonella. It indicated that the fried rice was not well processed. The train restaurant has to improve the fried rice prepared and sanitation to obtain a safe food product and to prevent the spreading of this bacteria. Key words: Salmonella, Salmonella detection, fried rice, train, restaurant
