Welcome Letter from the Rector of SUT
Dear Participants,
I would like to welcome all of you who have come to Bangkok,
Thailand, from all over the world. We are proud and honored to host
the 1st International Conference on Tropical Animal Science and
Production (TASP 2016). This year, Suranaree University of
Technology is celebrating its 26th Anniversary. Over the past 26 years,
we are proud to be consistently ranked as one of Thailand’s leading
universities, with a strong reputation for research excellence and
impact. This Conference is certainly a wonderful addition to our
calendar of 26th anniversary celebration activities.
The theme of this conference “Integrated Approach in Advanced Animal Science and
Innovation Technology” is appropriate in view of the orientation of technological and
institutional changes in such a manner as to ensure the attainment and continued satisfaction of
human needs for present and future generations.
If you take a look at the conference program, you will agree that this conference is going to be

Abstract
“Rambak” is the animal skin crackers product which one of the popular food products derived from
the animal by-products in Indonesia. For the religion reasoning the presence of pig derivatives in
any food products is prohibited for Moslem community. For this reason, the analytical methods
offering accurate and sensitive results are highly needed in order to assure the halal authenticity of
food. The objectives of this research is to developed the pig species specific primer for
identification of specific pig deoxyribonucleic acid (DNA) in “Rambak” cracker using polymerase
chain reaction ( PCR) analytical methods. This research used were four kinds of animal skin
crackers in individual or mixture samples. Skin mixture were prepared and divided into nine
formulas as follows 1) 100% pig; 2) pig 90%: cattle 10%; 3) pig 75%: cattle 25%; 4) pig 50%:
cattle 50%; 5) pig 25%: cattle 75%; 6) pig 10%: cattle 90%; 7) pig 1%: cattle 99%; 8) pig 0.1%:
cattle 99,9% ; and 9) 100% cattle. The same formula also prepared in mixture between pig skin
with buffalo and goat skin. DNA were isolated from the cracker products and applied in PCR using
perimer specific. The optimized PCR assay was subsequently validated for its specificity with
deoxyribonucleic acid (DNA) extracted from cattle, buffalo, goat and pig in individual or mixture
samples. Results showed the primers designed generated specific fragment of 510 bp length for pig
cytochrome b DNA. The specificity of the primers was tested on four animal species including pig,
cattle, buffalo and goat species. Analysis of experimental mixture meat demonstrated that 0.1% of
pig tissues could be detected using specific primer. The specificity of pig-specific PCR provides a
valuable tool for identification of pig skin and to avoid its fraudulent substitution and adulteration.
Keywords: pig species, identification, primer specific, cytochrome b gen

Introduction
“Krupuk Rambak” or Rambak cracker, is one of the traditional popular food in Indonesia,
made from thick skin of domestic animal. This food is traditionally hand made with traditional
process. One of the interesting issues in food industry is the authenticity of food products. The
quality assurance of food product can involve the alteration of the true labeling of food ingredients,
International Conference on Tropical Animal Science and Production (TASP 2016) st1 July 26-29, 2016 Ambassador Hotel, Thailand
[17]
in which the high value of raw materials are substituted by cheaper materials with similar
biochemical properties. Cattle or buffalo hide are expensive and can be altered with cheaper skin
such as pig skin.
The presence of pig derivatives such as pig skin, lard, pork and porcine gelatin in any food
products is a serious matter for moslem community (Mursyidi, 2013) , and also for Judaism and
Hinduism because some forbid their followers to consume any foods containing porcine and its
derivatives (Regenstein et al., 2003) . Therefore, it is necessary to evaluate the presence of these
pig derivatives in any products using some instrumental techniques. Some previous techniques
used are differential scanning calorimetry (Nurrulhidayah et al., 2015; Marikkar et al., 2012) ,
Fourier transform infrared (FTIR) spectroscopy (Rohman et al., 2011), gas chromatography-mass
spectrometry (Nizar et al., 2013) , high pressure liquid chromatography ( Saeed et al., 1989;
Marikkar et al., 2005) , electronic nose (Nurjuliana et al., 2011; Mansor et al., 2011) , and proton
nuclear magnetic resonance (Fang et al., 2013). Some of these methods are too laborious and time
consuming, consequently, an analytical technique offering rapid and reliable must be used. One of
the promising methods suitable for routine analysis is polymerase chain reaction- restriction
fragment lenght polymorphism (PCR-RFLP).
In the previous research we already developed the new technique based on the PCR- RFLP
technique for meat products determination using cytochrome b gen using universal primer and
resulted 360 bp DNA fragment. The determination was continued with restriction fragment length
polymorphism using BseD I restriction enzyme and able to cleave amplicon of cytochrome b gen
into 221 bp and 138 bp (Erwanto et al., 2012). This technique has been applied in detection of pig
derivative contamination in commercial meatball of Indonesia local market and showed positive
pig meat contamination of nine from thirty- nine samples ( Erwanto et al., 2014) . PCR- RFLP
technique has been established to determine of meat species contamination but still time consuming
and need two stage methods, first the amplification of gen target with universal primer and the
second, cleave PCR products using restriction enzyme. Therefore, in this study we developed the
species specific primer for distinguish of pig derivative particle based on cytochrome b gen in food
derivative products from animal skin.
Materials and Methods
Sample preparation and DNA extraction
Individual skin crackers samples of pig, buffalo, cattle and goat were obtained from local
market in Yogyakarta, Indonesia. Samples was prepared in laboratory with separate equipment to
prevent cross contamination. DNA was extracted and purified from skin cracker samples using
Sambrook et al. (1989) methods with slight modification. Approximately 30 mg of skins were
blended using a commercial blender and placed in a 1. 5 mL microcentrifuge tube. A- 500 μL of
Tris- EDTA- NaCl (TEN) buffer, 10 μL Proteinase K and 50 μL 10% Sodium Dodecyl Sulfate
(SDS) were added and mixed by vortexing and was incubated at 42°C in a water bath overnight.
After overnight incubation, 50 μL5 M NaCl, 400 μL phenol and 400 μL chloroform- isoamyl-
alcohol was added to the mixture and then incubated at 37°C for 1 h and centrifuged at 3,000 rpm
for 5 min. The supernatant was taken and put in a new microcentrifuge tube and mixed by vortexing
for 30 s, then 50 μL 5 M NaCl and 1 mL absolute ethanol were added, mixed vigorously and
incubated at –20°C for 1 h. The DNA was precipitated from the mixture after centrifuging at 8,000
rpm for 5 min, 4°C and the supernatant discarded. The 70% ethanol was gently poured off then
resuspended DNA for a second precipitation. The solution was then placed at room temperature
overnight. The resulting pellet was added with 50 mL Tris-EDTA (TE) buffer and stored at –20°C

for further analysis. Skin cracker samples were prepared by mixing of pig in buffalo, pig in cattle,
and pig in goat at a final concentration of pig at 0; 0.1; 1; 10; 25; 50; 75; 90 and 100%.
Design of pig specific primer
The nucleotide sequences of mitochondrial Cyt b genes from sus scrofa (pig) stored in
Genbank (www. ncbi. nig. gov) were taken and aligned using Primer3 website
(www.primer3.ut.ee/ ) . The set of primers used for amplification consisted of Cyt b-FW and
Cyt b-REV oligonucleotides as follows:
Cyt b FW 5’-CCC AGC CCC CTC AAA CAT CTC A-3’,
Cyt b REV 5’-ATG TAC GGC TGC GAG GGC GGT-3’.
Amplification of the Cyt b gene was performed in a final volume of 25 μL containing 100 ng
of extracted DNA, 20µL DreamTaq Green PCR master Mix ( Thermo Fisher Scientific) and 20
µmol of each primer. Amplification was performed with a thermal cycler according to the
following PCR step-cycle program: Pre-denaturation at 94°C for 2 min to completely denature the
DNA template, followed by 40 cycles of denaturation at 95°C for 36 s, annealing at 53°C for 73 s.
and extension at 72°C for 84 s. Final extension at 72°C for 3 min followed the final cycle for
complete synthesis of elongated DNA molecules. Six microliters of PCR products were mixed with
1 μL DNA Loading Dye (Thermo Fisher Scientific), then were electrophoresed at constant voltage
( 100 V) on 2% agarose gel ( TopVision, Thermo Fisher Scientific) for about an hour in 1×TBE
buffer, pH 8. 0 and stained by ethidium bromide. A- 100 bp DNA ladder ( GeneRuller, Thermo
Fisher Scientific) was used as size reference.
Results and Discussion
Total genom DNA form the various animal skin species was isolated using Sambrook et al.
( 1989) method with slight modification. During processing proteins are denaturalised due to the
time and temperatures of process and DNA should be employed for species identification
purposes. Therefore the susceptibility of the determination of species in food products depend on
the susceptibility in DNA extraction, without the extracted DNA the measurement of the detection
could not be continued.
DNA genom of four species could be successfully isolated (data not shown) although
there were some smear in goat skin sample. The quality of DNA and the level content of pig in
the crackers mix samples is important data for verifying the sensitivity of the method.
To identify pig skin in a large number of both processed and unprocessed skin crackers, we
carried out specific pig PCR amplification. With this fragment, pig has been detected in mixtures
treated with cattle, buffalo and goat skin crackers. Some commercial products were analyzed which
normally have cattle, buffalo or pig in their crackers product including in fresh skin crackers or
various processed skin crackers. Using the specific PCR amplification, we detected pig in various
concentration. Pig was detected until 0.1% contamination in mixture with cattle (Figure 1), buffalo
(Figure 2) or goat (Figure 3). In our some previous research showed the PCR-RFLP able to detect
pig DNA in heated meat mixtures at levels less than 1% based on fragment of the cytochrome b
DNA (Erwanto et al. , 2012) and Matsunaga et al. (1999) detected 250 pg of beef DNA, in DNA
mixtures. In raw pork and beef mixtures, Calvo et al. (2001) detected up to 0.01% beef in pork.
The choice of the technique to be applied is based on the results of sequence alignments.
Specific PCR seems to be best as a ‘ routine’ test, because it is easy, rapid and allows the
discrimination of several species at the same time (multiplex PCR), as well as the analysis of mixed

matrices. It is considered to be a robust method, mainly in comparison with other methods based
on the analysis of single nucleotide polymorphisms (Bottero and Dalmaso, 2011).

Conclusion
Specific PCR amplification of this fragment is a powerful technique for the identification
of pig contamination, due to its simplicity, specificity, and sensitivity (with 35 amplification cycles
we can detect 0. 1 % pig skin) . However, further research would be needed in order to develop a
quantitative method since this conventional PCR analysis is only qualitative.
