2. Background of the Study
Sandwiches are easy to prepare
Unhealthy consumption of preservative-loaded foods
Sweet potatoes are healthy
Sweet potatoes are affordable and can be easily bought in local markets

3. Statement of the Problem
This study deals with the feasibility of sweet potato as an ingredient in making a sandwich spread

4. Statement of the Problem
Sub-problems:
What are the characteristics of the different sandwich spread samples in terms of color, texture, aroma, taste, and consistency?
Is there a significant difference among the characteristics of the sandwich spread samples in terms of color, texture, aroma, taste, and consistency?
What is the acceptability of the different sandwich spread samples?
Is there a significant difference in the acceptability of the different sandwich spread samples?

5. Hypotheses
There is no significant difference among the different sweet potato sandwich spread samples in terms of their color, texture, aroma, taste, and consistency.
There is no significant difference among the different sweet potato sandwich spread samples in terms of their general acceptability.

6. Scope and Delimitation
Limited to the feasibility of sweet potato in making a healthy sandwich spread
Aims to determine which of the three samples is the most acceptable
Evaluation of the three samples was according to their characteristics and their general acceptability.
A board of 30 evaluators was chosen among the students of MSU-IIT IDS.

7. Methodology Preparation of sweet potato and other ingredients
Mixing all ingredients and blended with a blender
Put into separate glass containers and stored in a refrigerator

12. Summary of Findings All three samples has
two cups of ground sweet potato
2 teaspoons of calamansi extract
¼ teaspoon of vanilla
10 tablespoons of white sugar
Sample A has 1 cup of evaporated milk
Sample B has 1 cup of soy milk
Sample C has 1 cup of coconut milk.

13. Summary of Findings
Thirty evaluators were chosen to rate the products on a score sheet, given the Score Card and Hedonic Scale as their guides. Kruskal-Wallis Test was used to determine whether the samples have a difference in various characteristics. Sample A and Sample B are yellow, slightly smooth, have pleasant aroma, very sweet, and have very thick consistency. Sample A is liked very much by the evaluators, while Sample B was liked moderately. Sample C, on the other hand, is yellow, smooth, has a very pleasant aroma, sweet, and not so thick consistency and is liked very much by the evaluators.

14. Conclusions Sandwich spread can be made with sweet potato.
Different samples vary in characteristics such as color, aroma, and taste.
They do not differ when it comes to texture and consistency.
They differ in terms of general acceptability.

15. Recommendations Use another kind of sweet potato.
Try using powdered milk.
Put in more sugar or other sweeteners.
Add salt for better palate.
Observe the shelf-life of the sandwich spread.

16. End. Thank you. God bless. ^_^
