Provide a discussion of the differences in taste sensations. How does the sense of taste
“work”? How do individuals vary in the identification of sweet, sour (tart)? You could
also discuss bitterness and umami tastes. Were your results consistent with what is
expected?
I just need you to answer the question
and the results are available here
please put the references in APA format
Sensory Evaluation: Acidity/Tartness & Sweetness
Introduction
Food evaluation involves a multitude of various methods. The goal of this lab is to explore the subjective methods that are involved in such food evaluation. Tests that include sensory evaluation focus on factors such as taste, sight, and smell. Various people perceive these things differently and, for this reason, sensory evaluation methods are considered to be subjective. Such tests are often used by food companies for a variety of reasons. Companies look to sensory evaluation tests in order to see how well a given food is being enjoyed by the relative public. Gathering such information can serve to allow the company to improve products where needed, coordinate specific marketing strategies, and, hopefully boost sales of that particular product. One of the most crucial aspects of sensory evaluation is the sense of taste that we experience with various foods and beverages. This particular experiment looks at taste and how it relates to sensory evaluation of acidity and sweetness, respectively.
Objective
To explore how taste influences the assessment of food/beverages and understand how various preferences for acidity and sweetness make taste a subjective method of food evaluation.
Materials:
- Vinegar
- Small drinking cups
- Apple Juice
- Straws
- Pitchers (4X)
- Sugar
- Liquid Measuring Cup
- Spoons
Methods:
First we mixed the solutions in pitchers according to the table, then wrote 3-digit code on lab tape and labeled each samples. Placed 4 plastic cups for each student in class ( who is not familiar with the contents of the pitchers) to conduct the sensory evaluation of each sample. And then asked them ( 5 students ) to rank #1 the least tart to #4 the most tart for station Acidity ( tartness) and #1 as least sweet to #4 as the most sweet for station sweetness. Recorded our results in the tables below.
