Consumer perception and sensory effect of oxidation in savory-flavored yogurt enriched with n-3 lipids

Consumer perception and sensory effect of oxidation in savory-flavored yogurt enriched with n-3 lipids

Journal of Dairy Science Volume 95, Issue 4 , Pages 1690-1698, April 2012

Abstract

The objective of this study was to determine the effects of different oils (butter, fish, and oxidized fish) on sensory characteristics of a savory [chile-lime (CL)] low-fat yogurt using descriptive (unstructured line scales, 5 attributes) and affective (hedonic) sensory testing methods.

Yogurts were each manufactured at low [1.1–1.2% total fat; 0.43% added oil (wt/wt)] or high [1.6% total fat; 1% added oil (wt/wt)] levels of fish oil, with high levels of fish oil targeted to deliver 145mg of docosahexaenoic acid+eicosapentaenoic acid/170g of yogurt.

In a preliminary study, untrained panelists (n=31), using triangle tests, did not discriminate between low levels of fish and butter oils in unflavored yogurts but could discern yogurt with oxidized fish oil, even at the low level.

Trained panelists (n=12) described lower lime and acid flavor characteristics in CL-flavored yogurts containing 1% oxidized fish oil compared with yogurts containing low levels of oxidized fish oil and low or high levels of butter and fish oils. Oxidized flavor was higher in CL-flavored yogurts with oxidized fish oil (low and high) and with the high level of fish oil.

Consumer ratings (n=100; 9-point hedonic scale; 9=“like extremely) of overall acceptability and flavor acceptability were bimodally distributed, with overall means between 4 and 5 (“neither like nor dislike”) for CL-flavored yogurt with butter or fish oils (high level).

The upper 50% of responses for yogurt with butter or fish oil were 6.51 and 6.31, respectively, for overall acceptability (“like slightly”), and 7.02 and 6.56, respectively, for flavor acceptability.

A large segment of consumers may be interested in incorporating heart-healthy n-3 lipids in their diets through frequent consumption of a savory yogurt enriched with n-3 fatty acids… http://www.journalofdairyscience.org/article/S0022-0302(12)00134-8/abstract?elsca1=etoc&elsca2!=email&elsca3=0022-0302_201204_95_4&elsca4=nutrition_dietetics

Souvlaki
201 College Avenue P.O.B 263
Blacksburg, VA 24063

Mike Buchanan, owner.

According to the website, http://eatsouvlaki.com/, “Souvlaki opened for business in the fall of 1982. The original location was across the street on Draper Road. Souvlaki was associated with the original Greek's Restaurant, established in 1920 by the late Nick Kappas. Throughout the years the family has owned and operated four restaurants in the town of Blacksburg. While some continue under different management, Souvlaki still remains with the original family.”

Go Hokies!
