sensory testing for product dev
definition
scientific method used to evoke, measure, analyze and interpret those responses to products as preceved through the senses of sight, touch, taste and hearing
to evoke
preparation and serving of samples under controlled condition
using the light to mask the bias
minimize bias in responses
to measure
quantitative science
collect numerical data
determine the relationship product characteristics and human perception
discrimination
describing subjective perception
preference
to analyze
data analysis is an important part of sensory testing
human responses are often highly variable
need to use proper statistics and experimental design
to interpret
interpret information based on
hypotheses
background knowledge
implicatin for decision and action to be taken
conclusion --> should concern about methods used, limitations for the experiments, further research
importance
instruments lack the sensitivity of human sensory system
sensory provides useful informaton about human perception of product changes
ingredient/ processing / packaging
shelf life
safety
depend on microbes or characteristic of food
ex. stailing of bread
in product developement
measure consumer responses to product, product ideas, or specifc product quality
responses are based on sensory evaluation
idectify critical attirbutes of the product that determine the quality
identify undesirable chracteristics
determine simlarty differences between prototype and target product
compare between preference for prototype and competitior product
identify sensory attributes that need improvement
sensory evaluation tools
analytical test
discrimination
no preference
are products diff in anyway?
descriptive analysis
no preference
how do product differ nspecfic sensory charac?
affective test
preference + acceptance
how well are products liked or whch peoducts are preferred?
quantitative
preference
acceptance
qualitative
focus group
interview
observation
case example
development of sauce
determnation test to determine if prototype sauce diff from target or not
descriptive analysis to identify what the diff were
develop the product (ingredent, process)
prefernce tests to determine f both product were equally preferred
