Introduction

ood is an important aspect !or human" #asicall$ it pro%ide us energ$

!or dail$ &or's" As modernit$ is going !or&ard( people comes &ith %ariet$ o!

!ood productions to meet the demands and desires( to ser%e meals &ith the

)est diet *ualit$( to promote to others the ne& disco%er o! !ood recipes( andto ma'e people happ$ en+o$ing the )eauti!ul o! taste"

or Muslims( special consideration o! ,Halal- status need to )e !ollo&ed

as a compulsor$ guideline !or !ood consumption" .he esta)lishment o! ,Halal-

status )$ Allah /"0"." is a great gi!t and a proo! o! Allah-s merc$ to His

creatures" .he )enets o! consuming ,Halal- !ood co%er the ph$sical(

spiritual( emotional and intellectual aspects" In uran( one %erse that

mentions a)out ,Halal- is !rom the second %erse o! /urah Al#a*arah( 4

man'ind( eat !rom &hate%er is on earth 6that is7 la&!ul and good and do not

!ollo& the !ootsteps o! /$aitan" Indeed( he is to $ou a clear enem$8" .here

are man$ other %erses mentioned )$ Allah /"0"." in uran a)out ,Halal-issue"

Also the restriction o! ta'ing ,Haram- !ood( in%erse o! ,Halal- is

supported )$ a hadith narrated )$ /a$$idina A)u #a'ar A" rom him(

asulullah /A0 said that 44.hat )od$ &ill not enter Paradise &hich has )een

nourished &ith Haram8" Hadith )$ #aiha*i" .hus !or Muslim( ,Halal- and

,Haram- concept is a crucial consideration to )e o)ser%ed and &ell

esta)lished in li!e to achie%e the ultimate pleasure o! Allah /"0"."

Halal and Haram issues

/urel$ there are man$ issues regarding ,Halal- and ,Haram- o! the !ood

made and manu!actured outside there" In Mala$sia( Department o! Islamic

De%elopment Mala$sia 6:A;IM7 shares statements a)out some issues on the

&e)site( &hich related to ,Halal- and ,Haram- !ood"

/ome o! the issues are the production o! ne& t$pes o! !ood( animal

)ased and imported !ood ingredients( slaughtering method( !ood additi%es(

!acilities(


4/15

In the perspecti%e o! science( there are some possi)le and practical

&a$s to detect nonhalal constituents in the !ood sample" /cientists 'eep

&or'ing on nding eBcient approaches to trace nonhalal ingredient in order

to 'eep !ood in the mar'ets are %alid !or Muslim according to /hari-ah

compliance"

/ome techni*ues esta)lished and proposed )$ scientists are

1" Microscopic method"

2" Lipid)ased method" Anal$sis o! %olatile organic compound"


5/15

In accordance to this pro+ect( the molecular approaches &e interested

&ith are PC( electrophoresis and LAMP" or the denitional purpose( the

term ,molecular- re!ers to operation in%ol%ing cell( DA( A( protein and

AMP i) al)o an aplification techni4ue for i)otheral nucleic acid- It differ fro PR

techni4ue )ince it doe) not need the chan5e in teperature for denature: anneal and elon5ate-
