Brief Summary

Food is selected primarily on their taste and texture properties. It is essential to get more insight in taste and texture characteristics of the foods in the Dutch and Malaysian diets for a better understanding of food choices. Currently, there is insufficient information on taste and texture properties of foods to relate these properties to the composition of diets and individual food choice in larger (observational) studies. In the current study, the investigators want to assess the perceived intensities of the 5 basic tastes, i.e. sweet, salt, sour, bitter and umami, as well as fat sensation and texture, in an array of about 1,000 often consumed Dutch and Malaysian foods. The investigators aim to do this with a trained sensory panel, which is a well-accepted way of assessing perception of sensory attributes. With the current study, the investigators aim to build a table, which is comparable to the food composition table, but contains data that describes foods and meals in terms of sensory properties. That is, investigators want to quantify sensory characteristics of about 1,000 commonly eaten Dutch and Malaysian foods. This enables investigators to add sensory information to the food intake data that is already being collected in observational studies, and to further understand food choices in specific populations, such as elderly and patient groups. In current project, the investigators also aim to compare the Dutch diet to the Malaysian diet in term of sensory properties.

Outcome Measures

Primary Outcomes (3)

  • Comparison of panel performance results of two trained Dutch and Malaysian panelist

    For individual taste attributes of the reference solutions and reference foods, analysis of variance (ANOVA) was used to evaluate the performance of each panel on discrimination, repeatability and agreement according to the following model: Attribute= µ + product (P) + assessor (A) + replicate (r) + product\*assessor (P\*A) + product\*replicate (P\*r) + assessor\*replicate (A\*r) + E, where product= discrimination, assessor= consistency of ratings between assessors, replicate= consistency of ratings from one session to another, product\*replicate= panel repeatability, product\*assessor = agreement between assessors, assessor\*replicate= assessor repeatability. The replicate scores deviated from the product mean for all taste attributes from the total scale were also reported as root mean squared error (RMSE) of the ANOVA model without replicate effect

    Phase II training , an average of 3 hours visit per week

  • Dutch trained panelist-generated taste intensity ratings of commonly consumed Dutch foods

    The intensity rating of taste: sweet, salt, sour, bitter, umami and fat sensation on the 100-point quantitative Spectrum scales

    Through study completion, an average of 3hours visit per week

  • Malaysian trained panelist-generated taste intensity ratings of commonly consumed Malaysian foods

    The intensity rating of taste: sweet, salt, sour, bitter, umami and fat sensation on the 100-point quantitative Spectrum scales

    Through study completion, an average of 3hours visit per week

Secondary Outcomes (1)

  • The behavior measures of food texture related properties of commonly consumed foods

    Through study completion, an average of 3hours visit per week

Study Arms (2)

Dutch trained taste panel

The study population consists of a sample of 15 healthy Dutch males and females, recruited in the Wageningen area.

Diagnostic Test: Basic taste, fat sensation and texture perception

Malaysian trained taste panel

The study population consists of a sample of 20 healthy Malaysian males and females, recruited in the Subang Jaya, Selangor area.

Diagnostic Test: Basic taste, fat sensation and texture perception

Interventions

This is an observational Sensory study methodologically similar to "Astringency and bitterness perception clinicalTrials.gov identifier NCT03171402 "Participants are first involved in sensory training sessions that train how they recognise between different basic tastes and differentiate perceived intensity in solutions and foods. After 6 months of training, the trained participants are involved in tasting a wide array of commonly consumed foods. At this study phase, participants will rate for the foods' taste, fat sensation perception and texture
