The detection of blood thrombin enzyme presented in eight samples of surimi based products was investigated by using Polymerase Chain Reaction (PCR) method. Specific primers for chicken (Gallus gallus), cow (Bos taurus) and pig (Sus sucrofa) blood thrombin enzyme were designed for positive detection. Two primers for chicken blood which are Gal2 and Gal3 showed 98% and 99% in significant identity of G.gallus coagulation factor II (thrombin) while two primers from cow which are Bos4 and Bos6 showed 100% significant identity of B. Taurus coagulation factor II (thrombin). On the contrary, there were no positive results on pig primers with S. sucrofa coagulation factor II (thrombin). PCR amplification with Gal2 and Bos4 primers in surimi based products showed several positive results while Sus5 primer showed none. Further research should be done to verify the consistency of this result and redesign a specific primer for pig's blood thrombin enzymes is vital in order to guarantee the quality of food products to comply with Halal food guidelines and regulations. � IDOSI Publications, 2012.

The process of cooking may affect the fatty acids methyl esthers (FAME) content in food. The objective of this study is to determine the effect of grilling and roasting on FAME in beef and pork. Lipids were extracted using the Soxtherm fat extraction instrument. The fats were then methylated by sodium methoxide and being examined by using a gas chromatography. Data was analyzed using a one-way ANOVA. The amount of fatty acids in pork is significantly higher than in beef. The treatments within beef, showed significantly different values between the treatments. However, raw and grilled pork treatments were not significantly different except for the roast treatment (p<0.05). Ratio of polyunsaturated to saturated fatty acids (PUFA:SFA) in raw, grilled and roasted beef treatment are 0.03, 0.04 and 0.01. While in pork, raw, grilled and roasted treatments gives ratios 0.37, 0.33 and 0.30. This showed that pork has more PUFA content compared to beef. Further research can be done by changing the metod of extraction to see any difference between the methods. � IDOSI Publications, 2012.
