FOOD ADULTERATION

<h1 style="margin: 4.5pt 0in 0in 21.85pt; text-align: center;">FOOD ADULTERATION</h1></div></h1>Adulteration is defined as the process by which
quality or the nature of a given substance is reduced through. i.            
The addition of a foreign or an inferior substance. ii.             
The removal of a vital element. ·        
The word adulterated implies on element of deceit. ·        
It means mixing the food with something inferior or spurious. <o:p> </o:p> Food adulterant<div><div style="text-align: center;"> </div><div>    An adulterant is any material
which is or could be employed for making the food unsafe
or sub-standard or mis-branded or containing extraneous matter (FSSAI, 2006).<div>  Types of adulteration <o:p> </o:p> 1.     
Intentional Adulteration. 2.     
Incidental adulteration.   Intentional Adulteration <o:p> </o:p> ·        
Adulterant is added knowingly to increase profit. ·        
This type of adulteration includes intentional
addition, substitution or addition or removal of substances which adversely
affects the quality of food.</div><div>        Eg. Sand, marble chips, Earth and other filth. <o:p> </o:p> Incidental
Adulteration</div><div> </div><div>    Incidental contamination is due to ignorance, negligence or lack of
proper facilities.</div><div>        Eg. Toxic metals, presence of bacterial and
fungal contaminants. <o:p> </o:p> Metallic contamination <o:p> </o:p> ·        
Contamination of food with lead can cause toxic symptoms. ·        
Lead brings about pathological changes in the kidney, liver, and arteries. ·        
The common signs of lead poisoning are nausea,
abdominal pain, anemia, insomnia, muscular paralysis and brain damage. ·        
Fish caught from water contaminated with mercury salt contains large
amount of mercury. ·        
The other elements which are toxic in small doses are
cadmium, arsenic, antimony and cobalt. ·        
Food adulteration is unethical and called as Social Evil and A Slow Poison. <div>Food is
declared adulterated if: ·        
A substance is added which depreciates or injuriously affects it. ·        
Cheaper or inferior substances are substituted wholly or in part. ·        
Any valuable or necessary constituent has been wholly or in part abstracted. ·        
It is an imitation. ·        
It is colored or otherwise treated, to improve its
appearance or if it contains any added substance injurious to health. ·        
For whatever reasons its quality is below the Standard.   Categories of food adulteration <o:p> </o:p> ·        
Replacement:
Complete or partial replacement of a food ingredient or valuable
authentic constituent with less expensive substitute with the intention of
circumventing on “origin” and false declaration of the “process”. ·        
Addition: Addition of
small amounts of non-authenticated substances to mask inferior quality ingredient. ·        
Removal: Removal of
authentic and valuable constituent without purchasers knowledge </div><div> </div><div>Food Adulteration Categories.</div><div><div style="text-align: justify; text-indent: -24px;"> </div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjoBlaHK3M3v43pt_hwtAWhrJrbDjkrwCiD_41H4eTDHOOCF2CibmhiAnNH84tNjvq9QeOsry6-SCuVrvPl-AfecyfOQA7dPy4b-13QOzbnHdc01pngtqFGHgxa2hGh5YAPHgi0X3PjW81s0VFxu_fRsQ4-WEXhi5mVwyBZ_lEjGvarP-euXKfKFcpX" style="margin-left: 1em; margin-right: 1em;"><img alt="" data-original-height="997" data-original-width="892" height="580" src="https://blogger.googleusercontent.com/img/a/AVvXsEjoBlaHK3M3v43pt_hwtAWhrJrbDjkrwCiD_41H4eTDHOOCF2CibmhiAnNH84tNjvq9QeOsry6-SCuVrvPl-AfecyfOQA7dPy4b-13QOzbnHdc01pngtqFGHgxa2hGh5YAPHgi0X3PjW81s0VFxu_fRsQ4-WEXhi5mVwyBZ_lEjGvarP-euXKfKFcpX=w582-h580" width="582" /></a></div> <div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEgeo1GPWOVDHZiUrejimw30UN0t9o_Mp5XkHC_cBthJNvsdyYIkU-aWRKdltMErBnh-asG8RNz4BeZSpOdTvELsvKDuve9urAlmZfl1tVeJgKHHNRebiPoBWGCp04shzzXXDgfGp8KStqyPaivlr7MplGwLoTytrKeGfjMqLBBtvRouXcnOsSxQVeDy" style="margin-left: 1em; margin-right: 1em;"><img alt="" data-original-height="848" data-original-width="750" height="482" src="https://blogger.googleusercontent.com/img/a/AVvXsEgeo1GPWOVDHZiUrejimw30UN0t9o_Mp5XkHC_cBthJNvsdyYIkU-aWRKdltMErBnh-asG8RNz4BeZSpOdTvELsvKDuve9urAlmZfl1tVeJgKHHNRebiPoBWGCp04shzzXXDgfGp8KStqyPaivlr7MplGwLoTytrKeGfjMqLBBtvRouXcnOsSxQVeDy=w583-h482" width="583" /></a></div> </div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjIfsL87QIhLk3VQ_96nVqbA4zoWoDVJNuv7SYng9PUgJnol8tVh8pq68kWt4Yg8s99tm8Cw-w-lgCj581u3JfEHRHrN0BAwSd1v3ba46cAX3Rxnvy7szyoJC-PHKAyWAVYoJQrq1Tu4Chjeof1aMYXYH9OFEm90s3plgzsPS_PHPz_eglng-4pW_a5" style="margin-left: 1em; margin-right: 1em;"><img alt="" data-original-height="457" data-original-width="762" height="421" src="https://blogger.googleusercontent.com/img/a/AVvXsEjIfsL87QIhLk3VQ_96nVqbA4zoWoDVJNuv7SYng9PUgJnol8tVh8pq68kWt4Yg8s99tm8Cw-w-lgCj581u3JfEHRHrN0BAwSd1v3ba46cAX3Rxnvy7szyoJC-PHKAyWAVYoJQrq1Tu4Chjeof1aMYXYH9OFEm90s3plgzsPS_PHPz_eglng-4pW_a5=w586-h421" width="586" /></a></div><table cellpadding="0" cellspacing="0" style="text-align: left;"><tbody><tr><td height="0" width="146"></td></tr><tr><td></td></tr></tbody></table> </div><div>Methods for detecting food adulteration <o:p> </o:p> 1.
