Introduction
Food security is often conceptualized in the context of food
energy or calorie intake. However, it is increasingly recognized
that a large segment of the world’s population especially in
developing countries are consuming food that is deficient in
micronutrients like vitamin A and iron etc.(Vaclavik and
Christian, 2008). The manifestations of such micronutrients
deficiencies are vitamin A deficiency syndrome, night blindness,
xerophthalmia, anemia, goiter etc. In communities living in
developing countries, prevalence of poor diet and infectious
disease unite into a vicious circle. Moreover, they are most
important risk factors for illness and death, affecting millions of
pregnant women (Muller and Krawinkel, 2005). Diet based
strategies are considered to be one of the most efficient and
sustainable ways to overcome iron and vitamin A deficiencies.
Fortification of bakery products is given priority in recent times
as more number of bakery items are liked and consumed by
quite a number of people. Cake is an ideal vehicle for
fortification as it is a popular snack or dessert of all age groups
especially children and adolescents. As cakes are soft in texture
it is suitable for old people to consume without any difficulty of
chewing. Cakes are fun to eat and are consumed in events such
as social gatherings, party, seminar, or during a family gathering
as they have better appeal, taste, satiety and convenience,
however they are low in micronutrient content but high in fat.
Hence, fortification using locally available under exploited yet
nutritionally rich food is a good means of enhancing the
micronutrient content of cakes.
Materials and methods
A questionnaire was formulated and given to Adult
volunteers of age group of 20-35 years to know the consumer
preference in cakes. Lotus stem (Nelumbium nelumbo ) and
Carrot (Daucus carota) were chosen as food fortificants for
iron and carotene respectively. Lotus stem was purchased
from a village called Kadathampatty near Pudukottai and carrots
were procured freshly from the local market. After preliminary
preparations the edible portions of lotus stem was cut into fine
round shaped pieces and the edible portions of carrots were
sliced, blanched for two to seven minutes using hot water to
inactivate the native enzymes and cooled. Both the fortificants
were dehydrated by oven drying, and were ground into powder
(plate 1 and 2) and stored in High Density Polyethylene
(HDPE) covers for further use. Proximate analysis of moisture,
ash, iron , crude fibre and protein were estimated according to
the methods prescribed in NIN(2003). carotene and vitamin C
were determined using standard procedures by Ranganna
(2008) for the prepared fortificants.

Product development
Lotus stem powder and carrot powder were incorporated at
three levels viz 15 20 and 25 percent in both chocolate cake
(LSCK) and orange cake (CAOR). A standard chocolate and
orange cake were prepared as control as per the standard

ABSTRACT
Micronutrient malnutrition affects almost two billion people worldwide and food
fortification is considered as a major cost effective and sustainable solution. To enhance the
micronutrient content of cakes by food fortification using locally available under exploited
but nutritionally rich indigenous food fortificants. Lotus stem and Carrots were chosen as
food fortificants. The nutrient analysis of the fortificants was carried out. Lotus stem powder
(LS) and carrot powder (CA) were incorporated individually (15, 20 and 25 percent) as well
as in mixed form(MF) (2:1, 1:1, 1:2.) in Chocolate(CH) and Orange cake(OR) and the
highly acceptable cakes were analyzed for iron, carotene and quality parameters. Lotus
stem powder had iron(80mg/100g), carotene (543 μg/100g) and fibre(31.6 g/100g).Carrot
powder had iron(5 mg/100g), carotene(6875 μg/100g) and fibre(1.46g/100g).Among all the
variations LSCK
2
(84.5 percent), CAOR
1
(84 percent) MFCK
1
(88 percent) and MFOR
1
(87.3 percent) cakes were highly acceptable.LSCK
2
had the highest iron content
(12.50mg/100g) and CAOR
1
(760μg/100g) had highest carotene content. Total solids were
above the standard value of 60 percent. pH of MFCK
1
and MFOR
1
were 6.2.The microbial
count of the cakes was found to be within the satisfactory limit. Conclusion: Fortification of
cakes is a possible venture to alleviate micronutrient malnutrition in people.
