1 Alternative Sandwich Spread from Sweet Potato (Ipomoea batatas) Researchers:Anna Marie B. BoligorSandra Claire D. Sinahon
2 Background of the Study Sandwiches are easy to prepareUnhealthy consumption of preservative-loaded foodsSweet potatoes are healthySweet 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 HypothesesThere 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 spreadAims to determine which of the three samples is the most acceptableEvaluation 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 blenderPut into separate glass containers and stored in a refrigerator

12 Summary of Findings All three samples has two cups of ground sweet potato2 teaspoons of calamansi extract¼ teaspoon of vanilla10 tablespoons of white sugarSample A has 1 cup of evaporated milkSample B has 1 cup of soy milkSample C has 1 cup of coconut milk.
13 Summary of FindingsThirty 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.
