Alternative Sandwich Spread from Sweet Potato (Ipomoea

batatas)

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

Statement of the Problem

This study deals with the feasibility of sweet potato as an ingredient in

making a sandwich spread

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?

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.

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.

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

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.

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.

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.

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.

End.Thank you.God bless.
