Influence on Food Liking of Adding Spices to Replace Dietary Sugar

November 13, 2018 updated by: University of Colorado, Denver
This study aims to reduce the amount of sugar in a particular food item and add spices to see if the food liking of that item rates as high or higher in a post meal survey. Through the weekly feeding and testing of the menu items the investigators will determine an opinion of the participants. Results of these surveys will determine whether participants enjoy the reduced sugar options as much as their full sugar counterparts.

Study Overview

Completed

Conditions

Detailed Description

The Investigators will determine the overall consumer acceptability of a breakfast meal (tea and oatmeal) and a dessert (apple crisp) using a randomized, three-period, within subjects, crossover design. The three test conditions will be (1) Full sugar ("FS"), (2) reduced sugar (and calorie) with no added spice ("RS") and (3) reduced sugar (and calorie) plus spice ("RSS"). The two reduced sugar meals will be matched for calories. Subjects will taste each condition of the item on a separate day; tastings will be one week apart.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: full sugar recipe

Each subject was randomly assigned to one of six possible sequences to taste three recipes of each test item. Oatmeal and tea were served together and tastings occurred over three weeks; tasting of apple crisp occurred over three different weeks. Tastings of the three recipes occurred one week apart. The three recipes were full sugar recipe (FS), reduced sugar recipe (RS) and reduced sugar plus spice recipe (RSS). Each subject was randomly assigned to one of the below sequence schedules for each taste test whereby A, B, and C refer to one of the three recipes (FS, RS, or RSS):

Sequence 1: A, B, C Sequence 2: A, C, B Sequence 3: B, A, C Sequence 4: B, C, A Sequence 5: C, A, B Sequence 6: C, B, A

Subjects tasted three items (apple crisp, tea and oatmeal) in a randomized sequence schedule to allow for tasting the three recipes (full sugar recipe, reduced sugar recipe and reduced sugar plus spice recipe) over three weeks. Oatmeal and tea were served together as a breakfast meal and tastings of oatmeal and tea were done over 3 weeks and tastings for apple crisp (served alone) were done over 3 different weeks. Subjects tasted one of the three recipes at each weekly seating.
