ABSTRACT
Food color has a great impact on food consumption and production. Many
companies, restaurants and markets use the color perception theorytoincrease
their sales. Recent studies have shown the negative impact of the food colors. So
we analyzed the effect of synthetic food colors like orange red, lemon yellow,
kesar yellow and apple green on actively dividing root tip cells of Allium cepa.
Four different dyes were administered for thetreatment of activelydividingroot
tip cells for 7-day duration along with control. Mitotic analysis clearly revealed
the dye induced endpoint deviation like reduction in the frequency of normal
divisions in a dose dependent manner. Mitotic divisions in the control sets were
found to be normaldyehasinducedseveral chromosomalaberrations(genotoxic
effect) at various stages of cell cycle such as stickiness of chromosomes,
micronuclei formation, precocious migration of chromosome, unorientation,
forward movement of chromosome, laggards, and Chromatin Bridge.Amongall,
stickiness of chromosomes was present in the highest frequency followed by
partial genome elimination as micronuclei. The present study suggests that
extensive use of synthetic dye should be forbidden due to genotoxic and
cytotoxic impacts on living cells. Thus, there is an urgent need to assesspotential
hazardous effects of these food colors on other test systems like human and
nonhuman biota for better scrutiny.
KEYWORDS: Genotoxicity, Mitotic divisions, Chromosomal aberrations,
Unorientation, Chromatin Bridge, Cytotoxicity
Introduction
Food color is any dye or substance which impact color when
added to food. It is used both in commercial and domestic
cooking. It also makes food more attractive, appealing,
appetizing and informative. Hence people prefer foods
decorated with food colors, though artificial food coloring
makes food more appealing and attractive but they also
contain plenty of chemicals which are not safe for us.
Many food colors haven’t been tested enough to determine
the long-term dangers. Some studieshaveshown association
to certain types of diseases such as cancers, adrenal failure,
bladder failure, allergies etc. The need for avoidance of food
color is required because they only causegood perception to
food but do not have any nutritive value.
Preservatives, it only makes food attractive as visual aspect
is considered to be an important factor for the selection of
products. Hence we made an attempt to study four food
colors used in common used. TheyareOrange red(ablend of
sunset yellow and carmoisine), Lemon yellow (tartrazine),
Kesar yellow (a blend of tartrazine and sunset yellow) and
Apple green(a blend of tartrazine and brilliant blue CFC).
Allium cepa root tips have been used as test plant to study
the cytotoxic and genotoxic effects of food dyes.
Materials and Methods
Food Dyes
The different food colors which are used commonly in
household were collected for this experiment. The various
food colors which have been used in this experiment are as
follows: Orange red (a blend of sunset yellow and
carmoisine), Lemon yellow (tartrazine), Kesar yellow (a
blend of tartrazine and sunset yellow), Apple green(a blend
of tartrazine and brilliant blue CFC) .
Experimental plant
Allium cepa is the experimental plant which was employed.
To test the effect of food dyes , the root system of Allium
cepa was treated with four food dyes. Dried onion bulbs
were not used in this experiment.
Procedure
Sixteen Onion bulbs were allowed to germinate(3 in each
dye and 3 in water) in the 250ml beakerswith differentfood
colors(100mg)added to 100ml distilled water at room
temperature until the roots reached a length of 4-6cm for 1
week. These roots were collectedforthesquashpreparation.
Squash Preparation
The roots which were collected from the sixteen onion bulbs
that have been treated with water and food dyes were
analyzed. In the next step, few roots which had average size
of 5cm were then dipped in the fixative Carnoy’s solution

3:1(ethanol: acetic acid) for some time to allow the fixation
of the cells. After cell fixation, the roots were hydrolyzed in
HCl-Ethanol(1:1) solution in order to break the cell wall.
Then the root tip was cut with the blade and squashed by
tapping with the spatula. The roots were further stained by
treating of the onion root tips with 2% acetocaramine. The
root tip was placed on glass slide and a drop of
acetocaramine stain is added again once the squashing is
done. The slide is then covered with a cover slip .Excess of
stain was removed by the use of blotting paper and the slide
was exposed to flame for a while until it was warm. After the
squash preparation, these cells were then observed under
the compound microscope and for better magnification; oil
immersion was applied to the slide. The different stages of
mitotic division were then examined under the compound
microscope.
Results and Discussions
Allium cepa exhibits species level genomic constitution.
Present assessment showed the normal course of mitotic
division in the control set, that is, alignment of 16
chromosomes at metaphase and segregation of
chromosomes into 16:16 at anaphase. In untreated
meristematic cells (root tips) was registered with no
chromosomal manifestations.Ontheotherhand, treated sets
displayed the considerable range of irregularities during
mitosis that were found to be distributed in almost all
phases of division, that is, metaphase, anaphase, and
telophase.
As a consequence of irregular mitosis, several aberrations
were recorded, namely, precocious movement of
chromosome, unorientation, C-mitosis, forward movement
of chromosome, micronuclei formation at prophase and
telophase, chromatin bridge,and stickinessof chromosomes,
at metaphase and diagonal anaphase. Among all the
aberrations observed, stickiness was registered to be the
highest followed by micronuclei formation. Moreover some
other abnormalities have also been recorded such as
binucleate cell, unequal separation, and fragmentation.
In general, chromosomal aberrations are changes in
chromosome structure resultingfromabreakorexchangeof
chromosomal material and most often are permanent in
nature. Further investigations showed the dominance of
micronuclei after stickiness. Occurrence of micronuclei as
aberration might be the results of acentric fragments or
lagging chromosomes that fail to incorporate into either of
the daughter nuclei during telophase of the mitotic cells.
Thus, the micronuclei formation at telophase isattributed to
genetic loss through genome elimination of chromosomes.
Such genome loss plays a significantroleintheproduction of
aneuploids when occurring in germinal cells. Several
hypotheses have been suggested in anattempttoexplain the
phenomenon, including inactivation of chromosomes by
nuclease, formation of multi polar spindles, asynchrony in
nucleoprotein synthesis,genomeratios,spatialseparation of
genomes, and suppression of centromere function in the
eliminated chromosomes, asynchronous cell cycle phases,
and asynchronous mitotic and meiotic rhythms. However,
more precise explanation is still lacking.

Conclusion
Our study has shown that Food colors show severe cytotoxicity in terms of cell death. So, our present finding
clearly depicts the genotoxic and cytotoxic impact of different food colors on actively dividingroottipcellsof Allium cepa.This
investigation is also in agreement with several previous studies in the literature suggesting that there is an urgent need to
assess potential hazardous effects of these food colors on other test systems like human and nonhuman biota for better
scrutiny

This is an Open Access article distributed under the terms of the Creative Commons Attribution License (CC BY 4.0) (http://creativecommons.org/licenses/ by/4.0) ABSTRACT Food color has a great impact on food consumption and production. Many companies, restaurants and markets use the color perception theorytoincrease their sales. Recent studies have shown the negative impact of the food colors. So we analyzed the effect of synthetic food colors like orange red, lemon yellow, kesar yellow and apple green on actively dividing root tip cells of Allium cepa. Four different dyes were administered for thetreatment of activelydividingroot tip cells for 7-day duration along with control. Mitotic analysis clearly revealed the dye induced endpoint deviation like reduction in the frequency of normal divisions in a dose dependent manner. Mitotic divisions in the control sets were found to be normaldyehasinducedseveral chromosomalaberrations(genotoxic effect) at various stages of cell cycle such as stickiness of chromosomes, micronuclei formation, precocious migration of chromosome, unorientation, forward movement of chromosome, laggards, and Chromatin Bridge.Amongall, stickiness of chromosomes was present in the highest frequency followed by partial genome elimination as micronuclei. The present study suggests that extensive use of synthetic dye should be forbidden due to genotoxic and cytotoxic impacts on living cells. Thus, there is an urgent need to assesspotential hazardous effects of these food colors on other test systems like human and nonhuman biota for better scrutiny. KEYWORDS: Genotoxicity, Mitotic divisions, Chromosomal aberrations, Unorientation, Chromatin Bridge, Cytotoxicity Introduction Food color is any dye or substance which impact color when added to food. It is used both in commercial and domestic cooking. It also makes food more attractive, appealing, appetizing and informative. Hence people prefer foods decorated with food colors, though artificial food coloring makes food more appealing and attractive but they also contain plenty of chemicals which are not safe for us. Many food colors haven’t been tested enough to determine the long-term dangers. Some studieshaveshown association to certain types of diseases such as cancers, adrenal failure, bladder failure, allergies etc. The need for avoidance of food color is required because they only causegood perception to food but do not have any nutritive value. Preservatives, it only makes food attractive as visual aspect is considered to be an important factor for the selection of products. Hence we made an attempt to study four food colors used in common used. TheyareOrange red(ablend of sunset yellow and carmoisine), Lemon yellow (tartrazine), Kesar yellow (a blend of tartrazine and sunset yellow) and Apple green(a blend of tartrazine and brilliant blue CFC). Allium cepa root tips have been used as test plant to study the cytotoxic and genotoxic effects of food dyes. Materials and Methods Food Dyes The different food colors which are used commonly in household were collected for this experiment. The various food colors which have been used in this experiment are as follows: Orange red (a blend of sunset yellow and carmoisine), Lemon yellow (tartrazine), Kesar yellow (a blend of tartrazine and sunset yellow), Apple green(a blend of tartrazine and brilliant blue CFC) . Experimental plant Allium cepa is the experimental plant which was employed. To test the effect of food dyes , the root system of Allium cepa was treated with four food dyes. Dried onion bulbs were not used in this experiment. Procedure Sixteen Onion bulbs were allowed to germinate(3 in each dye and 3 in water) in the 250ml beakerswith differentfood colors(100mg)added to 100ml distilled water at room temperature until the roots reached a length of 4-6cm for 1 week. These roots were collectedforthesquashpreparation. Squash Preparation The roots which were collected from the sixteen onion bulbs that have been treated with water and food dyes were analyzed. In the next step, few roots which had average size of 5cm were then dipped in the fixative Carnoy’s solution IJTSRD23568

After cell fixation, the roots were hydrolyzed in HCl-Ethanol(1:1) solution in order to break the cell wall. Then the root tip was cut with the blade and squashed by tapping with the spatula. The roots were further stained by treating of the onion root tips with 2% acetocaramine. The root tip was placed on glass slide and a drop of acetocaramine stain is added again once the squashing is done. The slide is then covered with a cover slip .Excess of stain was removed by the use of blotting paper and the slide was exposed to flame for a while until it was warm. After the squash preparation, these cells were then observed under the compound microscope and for better magnification; oil immersion was applied to the slide. The different stages of mitotic division were then examined under the compound microscope. Results and Discussions Allium cepa exhibits species level genomic constitution. Present assessment showed the normal course of mitotic division in the control set, that is, alignment of 16 chromosomes at metaphase and segregation of chromosomes into 16:16 at anaphase. In untreated meristematic cells (root tips) was registered with no chromosomal manifestations.Ontheotherhand, treated sets displayed the considerable range of irregularities during mitosis that were found to be distributed in almost all phases of division, that is, metaphase, anaphase, and telophase. As a consequence of irregular mitosis, several aberrations were recorded, namely, precocious movement of chromosome, unorientation, C-mitosis, forward movement of chromosome, micronuclei formation at prophase and telophase, chromatin bridge,and stickinessof chromosomes, at metaphase and diagonal anaphase. Among all the aberrations observed, stickiness was registered to be the highest followed by micronuclei formation. Moreover some other abnormalities have also been recorded such as binucleate cell, unequal separation, and fragmentation. In general, chromosomal aberrations are changes in chromosome structure resultingfromabreakorexchangeof chromosomal material and most often are permanent in nature. Further investigations showed the dominance of micronuclei after stickiness. Occurrence of micronuclei as aberration might be the results of acentric fragments or lagging chromosomes that fail to incorporate into either of the daughter nuclei during telophase of the mitotic cells. Thus, the micronuclei formation at telophase isattributed to genetic loss through genome elimination of chromosomes. Such genome loss plays a significantroleintheproduction of aneuploids when occurring in germinal cells. Several hypotheses have been suggested in anattempttoexplain the phenomenon, including inactivation of chromosomes by nuclease, formation of multi polar spindles, asynchrony in nucleoprotein synthesis,genomeratios,spatialseparation of genomes, and suppression of centromere function in the eliminated chromosomes, asynchronous cell cycle phases, and asynchronous mitotic and meiotic rhythms. However, more precise explanation is still lacking.

So, our present finding clearly depicts the genotoxic and cytotoxic impact of different food colors on actively dividingroottipcellsof Allium cepa.This investigation is also in agreement with several previous studies in the literature suggesting that there is an urgent need to assess potential hazardous effects of these food colors on other test systems like human and nonhuman biota for better scrutiny
