 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Comparison of Consumer Acceptances of Frozen Pizzas Assessed at
Central Location Test (CLT) vs Home Use Test (HUT)) ผู้เขียน: Puntarika Ratanatriwong, May Suk Yeung, Citra Jusup, Matrid Ndife สื่อสิ่งพิมพ์:pdf AbstractSelection of sensory testing location plays an important role on the sensory evaluation. Not
only does test location define how product is sampled and perceived, but different results may be obtained
from different test sites with a given sample sets and consumers as well. This study was to investigate
the consumer perceptions on frozen pizzas as affected by various testing locations: central location test
(CLT) vs. home use test (HUT), and to determine if the tested products matched the consumer ideal
product profile. In CLT, 137 panelists assessed frozen spicy chicken and pepperoni using the acceptance
test based on various attribute categories: appearances, tastes, textures and overall acceptance. However,
data analysis (?=0.05) using chi-square and Student’s t-test was based on 46% of panelists who returned
HUT results. Both spicy chicken and pepperoni pizzas showed no significant difference of consumer
acceptances assessed in CLT and HUT based on all attributes except crispness and tenderness. Although
the overall taste of spicy chicken showed the potential (p=0.06) that test locations may show an influence
on consumer acceptance if more data was collected. Both frozen pizzas were not significant different
from the consumer ideal product profiles. CLT was recommended for the consumer acceptance test of
frozen pizzas due to its advantages in validity of responses, target consumer, convenient and economical
aspects despite a caution that some texture attributes were influenced by the test location. |
