1. The study evaluated the quality attributes of cookies flavored with Aidan (Tetrapleura tetraptera) as a substitute for vanilla. 2. Results showed that increasing the substitution level of Aidan for vanilla increased proximate nutrients but decreased carbohydrates and energy. 3. Cookies with 75% Aidan substitution had similar taste and crispness to the 100% vanilla cookie but were most acceptable overall to consumers.

INTRODUCTION
Idea of snacking is gaining ground with respect to its high frequency of
consumption world-wide, but the 21st century saw the revolution of
snack foods towards healthier snacks (Gabriel and Faith; Sumargo,
2016).
.
The use of natural flavours as substitute for commercial ones is a
promising strategy (Enzewereuzoh et al,. 2019; Olatoye et al,. 2019).
Substitution of natural flavouring spice for synthesized and imported
ones may bring about production of more healthy cookies and reduced
importation cost of foreign ones.

JUSTIFICATION
Rapid rate of urbanization has led into higher consumption of
snack foods, majority of which are flavoured with imported and
synthetic chemicals, amidst many indigenous alternatives.
Implications of this on production cost and healthiness of the
product can be averted by using natural flavourant alternatives.
 Aidan, an underutilized spice but with characteristic fragrant and
pungent aromatic odour has not been drastically explored for this
purpose in Nigeria.
Substitution of natural flavouring spice for synthesised and
imported flavours may bring about production of more healthy
cookies and reduced importation cost of foreign ones.

MATERIALS AND METHODS
• MATERIALS: The tetrapleura tetraptera,wheat
flour, sugar, salt and egg were purchased from Malete
market, Kwara state Nigeria.
• The pulp of tetrapleura tetraptera was pounded using
mortar and pestle to reduce its size and then milled
using an electric blender.
• Cookies were formulated according to method of
Eneche et al., (1999), with modifications.

Summary
The studies revealed that; with increase in substitution level of TT for
vanilla :
1. The proximate composition of the cookies increased, except
carbohydrate and metabolizable energy.
2. The cookie samples had higher mineral contents, except iron.
3. The cookie samples had reduced phytochemical contents .
4. The cookie samples were not significantly different in taste and
crispiness with sample TLZ(75% TT) compared most favourably
with SLT(100% VF) in overall acceptability.
5. Sample TLZ had higher mean score of ( 8.31) as overall
acceptability

CONCLUSIONS
• Cookies of improved nutritional and sensory qualities
can be produced by replacing 75% of vanilla flavour
with Aidan.
