RECENT DEVELOPMENTS IN HALAL FOOD ANALYSIS YAAKOB B. CHE MAN, Ph.D INSTITUTE OF HALAL FOOD Universiti Putra Malaysia In conjuction with the Annual General Meeting of MIFT, 20 May 2006, Subang Jaya, Selangor
Introduction
Increasing awareness of Muslim consumers on their religious obligations creates greater demand for halal food and other consumer goods
~ 2 billion Muslims out of > 6.5 billion world population
Majority are in OIC member countries
Organization of Islamic Countries (OIC)
Cont…
Trade in halal food is enormous - estimated annual halal food value ~ USD 347 (RM 1,317) billion globally
Lucrative market and huge opportunities for halal food business - domestic and international trade
Many companies are looking at halal concept as a new tool for marketing
Cont…
Halal is a Qur’anic term meaning ‘permitted, allowed or lawful’. Halal when used in relation to food and other consumer goods, means “permissible for consumption and used by Muslims’
Haram is the opposite of halal.
Shubhah or Mashbooh, means doubtful or suspected
Halal and haram are serious matters in Islam
Shariah Law means Islamic Law based on the Quran, Hadith, Ijma’ and Qiyas
A particular food or other consumer product becomes halal or haram if it is considered so through any one of the above mentioned sources or Fatwa (religious rulings) issued by competent Islamic Authorities.
The lives of every Muslims, including their dietary requirements, are guided by Shariah Law Cont…
Al Quran Surah Al-Baqarah: “ O ye people! Eat of what is on earth, Halal and good ; and do not follow the footsteps of the Evil One, for he is to you an avowed enemy.” (Verse 168)
Al-Quran Surah Al-Maidah “ O ye who believe! Forbid not the good thing which Allah hath made Halal for you, and transgress not. Lo Allah loveth not transgressors. Eat of that which Allah hath bestowed on you as food Halal and Good , and keep your duty to Allah in Whom ye are believers.” (verse 87 –88)
Hadith Bukhari and Muslim
“ Halal is clear and Haram is clear; in between these two are certain things that are shubhah (suspected ). Many people may not know whether those items are Halal or Haram . Whosoever leaves them, he is innocent towards his religion and his conscience. He is, therefore, safe. Anyone who gets involved in any of these suspected items, he may fall into the unlawful and the prohibition. This case is similar to the one who wishes to raise his animals next to a restricted area, he may step into it. Indeed for every landlord there is a restricted area. Indeed the restrictions of Allah are the unlawful (Haram).”
Cont…
Ensuring food and other consumer products authentically halal is obligatory for every Muslims
Hence, certification and verification of every item for halal compliance by competent Islamic Authorities, such as JAKIM, is extremely important
Halal Food Production - From Farm to Table Farm Raw material: *Animal *Plant Processing Handling e.g. slaughtering Processing/Unit Operations *Preliminary operation *Conversion operation *Preservation operation *Product development Ingredient & Additive Handling Packaging Storage Transportation Storage & Distribution Consumption
I Issues in Halal Food Production
Issues in Halal Food Production
Raw materials – animal or plant origin/imported
Slaughtering – according to Shariah/stunning
Processing operations/equipment – x-contamination
Packaging/Storage/Transportation (containers and vessels)
Food ingredients and additives
Pig and its by-products (e.g. pork, lard, gelatin)
Enzymes (e.g rennet)
Emulsifiers (e.g. E471 or mono- & diglycerides)
Alcohol (ethanol)
Biotechnology and GMOs (genetically modified organisms)
Safety and quality aspects (aspect of ‘Thoyyiba’)
Cont…
Halal is not just end-product certification but involves approval of all ingredients and all food processing at every stage of the production – from farm to table concept
Cont…
Due to breathtaking technological development today and the diversification of sources acquired globally for food processing and production - various kinds of processed foods are available in the market
It is very challenging and increasingly difficult for Muslims to ensure halal status of food in the market
This trend has raised concerns among Muslim consumers regarding new processed food
Cont…
Food is only halal if the entire food chain, from farm to plate, is processed, handled and stored in accordance to Shariah or Islamic Guidelines, e.g MS1500:2004, JAKIM’s Guidelines, Codex Alimentarious etc .
Adulteration of Food
Adulteration is an issue of major concern in the food industry globally
Adulteration of value-added food products - involving the replacement of high cost ingredients with lower grade and cheaper substitutes
Adulteration of food products can be very attractive and lucrative for food manufacturers or raw material suppliers
Adulteration with Porcine-based Products
In some countries, food manufacturers choose to blend vegetable fats with lard to reduce production cost
Lard could be effectively blended with other vegetable oils to produce shortening, margarines and other specialty food oils
In other instances, adulteration with porcine products could be unintentional
Al-Quran Surah 2: Verse 173
“ He has only forbidden you dead meat, and blood, and the flesh of swine and that on which any other name hath been invoked besides that of Allah. But if one is forced by necessity, without willful disobedience, nor transgressing due limits, - then is he guiltless. For Allah is oft-forgiving, most merciful.”
Cont…
Many fraudulent and deception cases reported worldwide involving adulteration of haram ingredients in halal food (especially porcine-based products), misuse of halal label, etc
E.g. In the U.K., Food Standards Agency conducted test for adulteration and authenticity of chicken using ELISA and DNA-PCR methods.
Test including samples with halal label revealed that chicken were adulterated with pig derivatives
Recent Issues of Processed Halal Food Fraud in Malaysia
Non-halal (pork) moon cakes with halal logo
Pigs and chicken stored together
Issue on bread using lard
Brushes using pig’s bristle (fur) in cake and bread preparation
Minced pork with halal label
Sausages with non-halal casing, expired halal certificate and old halal logo
etc
Cont…
In the past, many Muslims may have consumed processed food claimed to be halal but adulterated with non-halal ingredients and additives
Food producers/manufacturers/food service providers should be more sensitive and responsible to label their products.
Challenges in Halal Food Analysis
Halal food is sensitive and serious matter to Muslim
With many fraudulent issues around, more stringent monitoring should be established by the Islamic Authorities.
Authentication and verification for halal has become one of a major challenges in analysis of processed food
At present, very limited analytical methods available for halal food verification
Rapid and reliable methods are urgently needed for detection of non-halal components (e.g porcine origin) in food products
Cont…
Currently, Chemistry Department (MOSTI) is the official laboratory doing all halal food analysis
Received request for halal verification from various quarters :
JAKIM
KPDNHEP
Ministry of Health
Jabatan Agama Islam Negeri
Private companies
etc
Cont…
Current Methods of Analysis used for Halal Food Authentication
DNA-Polymerase Chain Reaction
DNA-sequencing
Gas Chromatography – FAC/FAME and TAG Analysis
Microscopic determinations
Chemical Testing
New Initiatives on Halal Food Analysis
JAKIM’s Halal Laboratories
UPM’s Halal Food Institute
National Reference Laboratory for Halal Products
Institute of Halal Food, UPM
Approved by Ministry of Higher Education and officially set up in 1 June 2005 in UPM
Objectives:
to carry out R & D on halal food production
to develop new methods for halal food analysis
to provide professional services on halal food related matters
to actively contribute together with other agencies towards achieving Malaysia’s vision to be a Global Halal Food Hub
Cont…
IMH developed several new analytical approaches for detection of halal food adulteration
Since porcine-based products are widely used in food and is the biggest issue in halal food, we are developing techniques for detecting pork and lard in some food items claimed to be halal
Cont…
Development of Potential Methods for Detection and Monitoring of Halal Food
Fourier Transform Infrared (FTIR) spectroscopy
Electronic Nose (E-nose) technology
Differential Scanning Calorimetry (DSC)
Molecular Biology techniques
FTIR Spectroscopy
Food samples (chocolate, cake, biscuits) were analyzed to identify the differences in FTIR spectra profiles
FTIR technique combined with chemometric analysis was able to detect and quantify the level of lard adulterated in food samples (3% detection limit)
Offers rapid (results in 2 min), simple, accurate, reliable, and environmental friendly tool

Electronic Nose (E-nose) Technology
An instrument, which comprises an array of electronic chemical sensors and appropriate pattern recognition system, capable of recognizing simple or complex odor or smell
This technique was applied to monitor the presence of lard in food sample such as cooking oil
Qualitative identification of adulterated oil is possible by the characteristic 2-dimensional olfactory images called VaporPrint TM

Protein-based technique
ELISA is used to determine the level of antibodies in a sample and useful because they are specific and are relatively simple to perform.
We developed method for detection of pig derivatives qualitatively in the food samples using ELISA technique
The analysis yielded excellent results for detection of pig derivatives in samples
