"Penelitian ini telah berupaya untuk meningkatkan tekstur keju yang dibuat dari susu sapi segar, dengan menggunakan pengganti enzim rennet sebagai koagulan. Susu mengandung dua protein utama yaitu kasein dan whey. Namun bagian yang penting untuk dijadikan keju adalah kasein, di mana kasein ini yang mengalami koagulasi untuk membentuk produk keju. Koagulan yang digunakan adalah kombinasi enzim papain dan transglutaminase.
Berdasarkan penelitian-penelitian sebelumnya, enzim papain bisa digunakan untuk mengkoagulasi kasein susu menjadi keju karena kemampuan proteolitiknya. Enzim transglutaminase digunakan untuk meningkatkan tekstur keju, dengan kemampuan ikatan silangnya. Proses pembuatan keju ini terdiri atas tiga variasi konsentrasi enzim papain yaitu 0,5; 1,5; dan 2;5 gram/100 ml susu untuk menentukan yield yang dihasilkan paling banyak, dan variasi kadar enzim transglutaminase sebesar 0,5; 1; 2 UE/gram protein susu atau setara dengan 0,027; 0,054; dan 0,11 gram enzim/100 ml susu.
Pada sampel keju terbaik yang dihasilkan dilakukan pengujian seberapa banyak yield, pH, uji FTIR, uji proksimat, mikrostruktur keju, uji potensial zeta, dan uji profil tekstur. Yield yang dihasilkan sebesar 23,33%, dengan pH 6,3, dan nilai puncak potensial zeta 0,97. Mikrostruktur keju yang diamati menggunakan Scanning Electron Microscope dengan perbesaran menunjukkan penambahan TGase menyebabkan koagulum lebih memadat. Nilai proksimat yang didapat menandakan penambahan TGase meningkatkan kadar lemak dan karbohidrat, dan menurunkan kadar air dan protein. Profil tekstur yang didapat menandakan keju dengan TGase lebih keras dan elastis karena adanya peningkatan kandungan lemak dan ikatan silang lebih lanjut pada matriks protein oleh TGase"

SUMMARY
Food deterioration is often due to lipid oxidation, excluding bacterial and
enzymatic spoilage. The end-products of lipid oxidation, such as aldehydes,
ketones, and alcohols are responsible for unacceptable off-tiavors and off-
odors in food. Lipid oxidation can be inhibited by antioxidants.
Soybean tempe is the most popular indigenous fermented food in
Indonesia. Soybeans are known to contain isotiavones. Four major forms are
known respectively as acetylglycosides, malonylglycosides, glycosides, and
aglycones.
Tempe were produced from soybean fermentation by Rhizopus oryzae
UICC 524 and Rhizopus microsporus var. chinensis UICC 521. The tempe
samples were extracted with methanol and the extraction defatted with hexa»
ne. The isoflavone aglycones were isolated using column chromatography,
and then anaiyzed using a gradient elution reverse phase of high-pressure
liquid chromatography (HPLC). After HPLC analysis, isotiavone aglycones
were evaporated to dryness and added to soybean oil at the 100, 200, 300,
iii ' and 400-ppm concentration in test tubes, then heated at 170°C for 30 minu-
tes. The oxidation of soybean oil was measured using the thiobarbituric acid
(TBA) test. The result, called thiobarbituric acid reactive substances
(TBARS) value, was expressed as pmolll and compared to the synthetic
antioxidant, buthylated hidroxytoluene (BHT), at the same concentration.
The profile of isoflavone aglycones isolated contains daidzein and
genistein. No factor-2 (6,7,4'-trihidroxyisoflavone) and glycitein were detec-
ted. Daidzein resulted from biotransformation of daidzin was dominant in
both tempe samples. The isoflavone biotransformation was much greater by
R. microsporus var. chinensis UICC 521 than by R. oryzae UICC 524, except
for the 24 hours incubation. After 72 hours of incubation, the total isoflavone
aglycones in tempe using R. microsporus var. chfnensis UICC 521 was
721.6 pglg and when using R. oryzae UICC 524, 268.2 p.glg.
The oxidized soybean oil without any antioxidants had a TBARS value of
327.32 1 20.31 pmol/1. Addition of the antioxidants showed a decreased
TBARS value following increasing concentration for both. For concentration
until 300 ppm, the TBARS values of oxidized soybean oil added with isofla-
vone aglycones were greater than when added with BHT, respectively
55.40 zl: 2.77 pmol!! and 45.20 i 2.63 pmolll. However at concentration of
400 ppm, the TBARS values of oxidized soybean oil added with isoftavone
aglycones and added with BHT did not show a significant difference.

"Dalam penelitian ini, penulis mencoba untuk mengembangkan keju yang dibuat dari susu unta karena potensi dari susu unta sendiri berdasarkan literatur yang ada sangatlah bagus. Untuk menggantikan enzim rennet sebagai koagulan, digunakan enzim papain sebagai alternatif. Enzim papain terdapat dalam getah papaya yang dibuat dengan cara menyadap getah papaya kemudian diproses lebih lanjut untuk diperoleh enzim papain.
Penelitian dilakukan di laboratorium, dimulai dari proses pembuatan enzim papain, proses koagulasi, dan di akhir, keju hasil dari masingmasing penggumpalan dengan koagulan berbeda dianalisa dengan analisis proksimat untuk diketahui kadar protein, kadar lemak, karbohidrat, air dan abu, analisis potensial zeta untuk mengamati kestabilan larutan, uji pH dan uji organoleptik untuk memastikan hasil keju yang dihasilkan berkualitas baik dan dapat diterima oleh masyarakat.
Berdasarkan hasil penelitian, keju terbaik dihasilkan dari hasil ekstraksi enzim papain dengan pencampuran getah 3 ml dengan aquadest hingga 10 ml ketika suhu susu 70oC, yang menghasilkan keju dengan yield 13,22 gram; pH 5; kadar protein 25,00%; kadar air 56,40%; kadar abu 0,59%; kadar lemak 0,78%; kadar karbohidrat 17,20%; dan nilai potensial zeta -11,59 mV. Dari segi organoleptik, aspek yang paling menonjol adalah aroma dan yang dianggap kurang adalah warna dari keju.

In this research, writer is trying to develop a cheese made from cow milk because the potential of camel milk itself according to existing literature is very good. To replace rennet enzyme as the coagulant, papain enzyme is used as the alternative. Papain enzyme exists in papaya latex which can be made by extracting papaya latex then processed further to obtain the enzyme.
The research is done in a laboratory, from the making of enzyme, coagulation process, and in the end, cheese obtained from each coagulation process with different coagulant will be analyzed with proximate analysis to know the amount of protein, fat, carbohydrate, water and ash, zeta potential analysis to know the stability of the colloid, pH analysis and organoleptic analysis to ensure that the quality of the cheese made in this research and can be accepted in the society.
Based on the research, the best cheese resulted from mixing papain enzyme extracted from papaya with 3 ml of sap, diluted by aquadest until 10 ml that was added on 70oC, which resulted cheese with 13,22 gram of yield; pH 5; 25,00% of protein; 56,40% of water; 0,59% of ash; 0,78% of fat; 17,20% of carbohydrate and it has -11,59 mV on its zeta potential value. From organoleptic analysis, the best aspect from the cheese was the aroma while the color of the cheese is considered as the least best.
