5.0 CONCLUSION
A two-level factorial was used to formulate avocado fruit spread using four factors at specific
levels as: 50 g of avocado pulp, 5 g of sugar, 9 g miscellaneous and 0.5 g of the xanthan gum.
Sample M2(732) which was the most preferred had its responses evaluated as: Colour (0.52),
Taste (0.64), Aroma (0.71), Spreadability (0.72) and Finger feel (0.80).
For the microbial load, the shelf life was determined to be 47.50 days and 37.49 days for the
samples stored at refrigeration and ambient conditions, respectively. For the peroxide value, the
shelf life was 70.15 days and 40.26 days for the samples at refrigeration and ambient conditions,
respectively. The colour of the sample provided a shelf life of 69.00 days and 30.10 days for the
products kept under refrigeration and ambient conditions, respectively.
For most food products, microbial load is the principal food safety concern. For this project,
therefore, it was submitted that the shelf life should be contingent on the safety issue-microbial
load-whilst the quality issues-peroxide values and colour-would guide the final/commercial
presentation of the product.
From the results obtained, the shelf stability of the avocado fruit spread was determined to be
47.50 days under refrigeration conditions, which is significant considering the short shelf life of
the fresh fruit.
Q10 and activation energy (Ea) values of 1.74 and 8.80 kcal/mol respectively were obtained for
the chemical deterioration due to increasing peroxide values. For chemical deterioration due to
decreasing colour intensity, values of 2.29 and 13.17 kcal/mol were obtained for Q10 and
activation energy (Ea) respectively.
