Consumers’ sensory acceptance of food products is complex and interdisciplinary, encompassing all aspects of food science, marketing, nutrition, psychology and hospitality1
. Acceptance depends on many things: sensory attributes, consumer physiological, behavioral and cognitive factors2,3
and the ability to understand these variables is important.
Research shows that cues: intrinsic and extrinsic, help to study sensory acceptance. Intrinsic characteristics, including taste, aroma and color often cannot be altered without changing the nature of the product and these characteristics are usually specific to the product. Extrinsic characteristics include brand name, price, advertisement, labeling and country of origin4
. The U.S. has become interested in also knowing about quality attributes such as food safety, animal welfare and organic production5
No matter which cues are being tested, in order to collect as much information as possible from consumers, it is necessary to consider the amount of information provided in the study. Blind testing is defined by Moskowitz6
as evaluating products without the benefit of product identification. Branded testing is evaluating products with some product knowledge given to the consumer. Moskowitz6
said that when a consumer assigns an attribute rating to a product without knowledge of product identification, ratings may dramatically change when they are given the identification.
According to Siret and Issanchou7
, labeling usually is considered to have a positive effect on overall acceptability. Bower, Saadat and Whitten8
evaluated 70 consumers and looked at the effect of liking, information, and consumer characteristics on purchase intent and willingness to pay more for two fat spreads with proven health benefits. Unlabeled testing showed significant differences in overall liking of the spreads and purchase intent. Labeled testing also showed a significant difference in overall liking when information was provided. Results showed that purchase intent was significantly affected by label information, such as price and nutritional benefit. The significant difference in liking between the two spreads contributed to the intention to buy, with higher purchase intent for the product which was liked more. This study indicates that consumers are aware of the label information on products.
Other times labeling could have a negative effect on consumer acceptability. Cues often are communicated by the media to influence consumers’ liking of different products8
. Berger and Mitchell9
showed that advertising can influence more than just the evaluation dimensions of attitudes. It can influence how easily an evaluation is accessed from memory, how confidently it is held and how likely it is to influence subsequent behavior. For example, Siret and Issanchou7
found that non-traditional information provided on ground pâtés from France created low expectations and had a negative effect on visual evaluations. Levis and Chambers10
showed that labeling products as low salt reduced scores for low salt potato chips, which they associated with negative perceptions about more healthful products at the time. When consumers have a negative acceptance of a product it can lead them not purchasing the product. Deliza and MacFie11
stated that how advertisements are presented, as well as the price and appearance, can appeal to consumers differently.
If testing of consumer acceptance is the study objective, then considering the effect of labeling will be important to successful results. It is widely known that sensory properties are important to determine consumer liking of products and paying attention to the effect of different types of labeling could enhance knowledge in the product category. Incorporating label information and not manipulate the data being collected leads to a successful learning experience of the product.
