ABSTRACT
Two hundred nine fortified high energy biscuit (HEB) samples from seven different locations were collected
and examined for moisture, ash, protein, fat, crude fiber, sugar, carbohydrate and energy by AOAC methods.
Iron was estimated by Flame Atomic adsorption spectrophotometer (FAAS) and vitamin A by High
Performance Liquid Chromatography (HPLC). While mesophyllic aerobic bacteria, coliforms, escherichia coli,
salmonella, staphylococcus, bacillus cereus, enterobacter spp. and yeasts & moulds were tested for microbial
contamination. In the physicochemical examinations such as food energy value, protein, fat, iron and vitamin A
content of some fortified high energy biscuits did not comply with the World Food Programme (WFP)
permissible limits but moisture, sugar and microbial loads of most of the fortified high energy biscuits were in
the permissible limits. The physicochemical analysis showed that there was no significant difference observed
among the industry wise category of biscuit samples in the analysis of moisture, protein, sugar and ash. While
significant differences (p<0.05) were observed in fat, carbohydrate, vitamin A, iron and energy content. It was
concluded that a substitution of biscuit ingredients by biscuit industries can improve the quality of fortified high
energy biscuit and thus the acceptability of these biscuit will increase to the WFP.
Key words: World Food Programme (WFP), AOAC, FAAS and HPLC.
INTRODUCTION
Biscuits are nutritive snacks produced from
unpalatable dough those are transformed into
appetizing product through the application of heat
in an oven
1
. They are ready-to-eat, convenient and
inexpensive food product those containing
digestive and dietary fibre with principles of vital
importance
2
. The principal ingredients are flour,
fat, sugar and water while other auxiliary
ingredients such as milk, salt, flouring agent and
aerating agent are used for making biscuit
3
. Biscuit
is a rich source of fat and carbohydrate and it is
high energy giving food. They are also a good
source of protein and minerals
1
. The nutritional
value of biscuits varies with the type of cereal used.
Biscuit generally contains fat (18.5%),
carbohydrate (78.23%), ash (1.0%), protein (7.1%)
and salt (0.85%)

.
Among ready-to-eat snacks, biscuits possess
several attractive features including wider
consumption base, relatively long shelf-life, more
convenience and good eating quality
5&6
. Long
shelf-life of biscuits helps to give large scale
production in short time and distribution of this
biscuit in whole over the country is possible for a
long time. Good eating quality makes biscuits
attractive and therefore, protein fortification and
other nutritional improvements are essential for
good quality of biscuit. Development of fortified
biscuits or other composite flour bakery products is
the latest trend in bakery industry. The growing
interest in these types of bakery products is due to
their better nutritional properties and possibility of
their use in feeding programs and in catastrophic
situations such as starvation or earthquakes
7
.
Biscuits are the most popularly consumed bakery
items in the world. Some of the reasons for such
wide popularity are their ready to eat nature,
affordable cost, good nutritional quality,
availability in different tastes and longer shelf life

Food spoilage is a metabolic process that causes
foods to be undesirable or unacceptable for human
