Conclusion
Three different varieties of citrus were processed and made into fruit juice. Juice
A was made from Lemon, Juice B was made from calamansi and Catsup E was made
from passion fruit. Several ingredients were mixed into the mixture to create home-made
citrus fruit juice from raw materials. Then the products were subjected to taste test with
thirty respondents and several factors were evaluated such as color, acidity, aroma, taste
and general product. Out of the three treatments, Juice E ranked the highest for color,
aroma, taste and general acceptability. Juice A ranked as the highest for the acidity.
However, it ranked last for the color. Juice B ranked in the middle for almost all the factors
except the acidity as it ranked second.
