Publication The Academia's Multidisciplinary Approaches in Providing Education, Scientific Training and Services to the Malaysian Halal Industry(IDOSI Publications, 2013) ;Alina Abdul Rahim ;A.R. Norhayati Rafida ;H.K.M.W. Syamsul ;A. Siti MashitohM.H.M. YusopAbstract: The major challenge faced by the Halal industry is the shortage of knowledgeable work force thatunderstands syariah requirements and implementing this theoretical knowledge into actual industrial practice.This paper highlights a multi-disciplinary approach towards Halal education, scientific training and services.As a multi-racial country, in Malaysia, one needs not necessarily become a Muslim, in order to be activelyinvolved in the Halal services and production line. Ignorance, confusion or deliberate fraudulent practiceswill consequently result in the presence of adulterants or contaminants in the product, making it Haram orSyubhah with negative consequence on Halal branding. The Halal integrity and values are thus compromised.The Malaysian Standard MS 1500:2009 and the Trade Description Act 2011 are legal guidelines, mandatory forthe acquiring of the Malaysian Halal logo. Understanding the principles and practices ofHalalan andthoyyiban, with hands-on knowledge that meets industrial needs and demand, is necessary to cater for the rapidexpansion of the Halal industry and to achieve compliance. As a niche-comprehensive university, UniversitiSains Islam Malaysia have collaborated with the Halal industry and government agencies in the developmentand implementation of training modules for meat slaughterers, laboratory analysts and those involved in theareas of food, pharmaceutical, cosmetics and consumer goods. The Halal Executive Program with HDC wasdone, to fulfill the needs for trained human resources for the monitoring and surveillance agencies. This holisticinitiative of combining syariah knowledge with technology has benefited the Halal industry, the NGOs,education system and the Muslim communities and consumers.

Publication Comparison Between Solvent Extraction Using Gas Chromatography Mass Spectrometry Triple Quadrupole (gcms-qqq) Of Cholesterol And Cholesterol Oxidation Derivatives(IDOSI Publications, 2013) ;M.H.M. Yusop ;Z. Norzaimah ;Z.H. Shazamawati, ;M.J. Thema Juhana ;A. Siti Mashitoh ;K.M.W. SyamsulA.R. AlinaAbstract: Cholesterol Oxidation Products (COPS) are well known for their negative biological effects. Till now,there is no study reported on solvent extraction used for COPs. In this study, two solvent extractiontechniques, namely chloroform/methanol (2:1, v/v) or Folch method and n-hexane/2-propanol (3:2, v/v) orHara-Radin method of cholesterol and COPs in beef tallow and lard were compared. Cholesterol and COPs(5-cholestane, 7-ketocholesterol and 25-hydroxycholesterol) contents in both fats also analyzed. The analysispassed through four major steps; extraction of lipids, saponification, enrichment of COPs and quantificationby gas chromatography mass spectrometry triple quadrupole. All standards showed good linearity withcorrelation coefficient (r ) of 0.9998 (5-cholestane), 0.9999 (cholesterol), 0.9873 (25-hydroxycholesterol) and20.9693 (7-ketocholesterol). Data obtained by this method was analyzed based on precision and recovery criteria.Precision measured as standard deviation (SD) was between 0.0040 and 2.2460; and no significant different(P>0.05) for the recovery testing using 5 -cholestane in both method. Recovery by Hara Radin method in lard(27.23%) and beef tallow (8.73%) was higher than the Folch method, 14.25% and 2.97% respectively. This studyimplies that Hara-Radin method can be an alternative method to avoid the use of harmful solvent such aschloroform in Folch method.

Publication Detection of Blood Transglutaminase Enzyme in Fish Surimi Based Product by Using Polymerase Chain Reaction (PCR) Method(IDOSI Publications, 2013) ;A.R. Alina ;Nurul A.S. Aqilah ;M.H.M. Yusop ;K.M.W. Syamsul ;N.R.S.A. Syarifah ;A.Siti Mashitoh, ;A.S. Nadia Syuhada, ;H.S. Ummi Syuhada, ;A.Nurul Farah Sakinah, ;A.H. Nurul Mawaddah, ;S.NurulhudaM.A. Kal-KausarAbstract: Blood plasma contain transglutaminase (TGase) enzyme - catalyst the reaction of cross-linkingbetween proteins which has a significant impact on properties of protein gel capacity, thermal stability, waterholding capacity thereby protein characteristics elasticity, mouth feel, flavour, texture, binding force. Theobjectives of this study are to design and analyze the specificity of oligonucleotide primers of blood plasmatransglutaminase from chicken, bovine and procine blood and to detect the presence of blood plasmatransglutaminase in eight samples of fish surimi based products using PCR method. In this study, PolymeraseChain Reaction (PCR) method has been used in detecting the existence of blood transglutaminase enzyme DNAin surimi based products. Specific primers for chicken (Gallus gallus), cow (Bos taurus) and pig (Sus scrofa)blood transglutaminase enzyme were designed for positive detection. Two of the six primers designed for thechicken blood tranglutaminase, G3 and G5 have shown 99 % significant identity to the sequence of G. gallussimilar to XP-C repair complementing (transglutaminase) and the latter to the hypothetical LOC428804(transglutaminase) sequence. However, there was no positive result using the six primers designed forBos taurus transglutaminase and the six primers designed for S. scrofa transglutaminase. PCR amplification withG3 and G5 primers in surimi based products also showed negative results. Based on this study, G3 primersequence for chicken showed 99 % of G. gallus similar XP-C repair complementing (transglutaminase) followedby G5 primer which also obtained 99 % G. gallus hypothetical LOC428804 (transglutaminase) of significantidentity. However, for primer of cow and pig, there were no positive results. On the contrary, PCR amplificationon surimi based products had not showed positive bands of chicken blood transglutaminase, G3 and G5 in thesamples. Further research should be done to verify the consistency of this result and to redesign the primersfor cow and pig’s blood transglutaminase enzymes in order to increase its specificity which is vital in assuringthe reliability of the detection method in food products in accordance to the Halal food guidelines andregulations.
