Trial summary

Dairy-based beverages contain fat and sugars. As both contribute to the energy intake upon consumption, food industry strives to reduce these ingredients while maintaining the taste, texture and aroma properties of the beverages. Read more about this study

About this study

Official title: Validation Study to Evaluate the Use of Acoustic Tribology to Assess Mouthfeel of Dairy Drinks

Dairy-based beverages contain fat and sugars. As both contribute to the energy intake upon consumption, food industry strives to reduce these ingredients while maintaining the taste, texture and aroma properties of the beverages. A successful reduction of fat and sugar from drinks has still proven a great challenge since consumers have less preference for the mouth feel of reformulated beverages than for the regular beverages. Mainly because instrumental measures like rheology and traditional tribology do not entirely predict the experienced mouth feel, there is an interest in alternative correlates for mouth feel aspects related to fat and sugar perception. In a recent study it was demonstrated that vibrations produced during interaction between the tongue, palate and beverages during consumption are very sensitive to the amount of fat and texturizers in the beverage. The present study aims at clarifying that relation for a larger panel of human subjects, by systematically evaluating vibration spectra during consumption of dairy beverages that differ in fat content, sugar content or pH. Secondly, the correlation of vibration spectra (acoustic tribology) with mouth feel-related sensory properties and composition of fat deposits on the tongue will be assessed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Powers in segments of time-frequency transferred vibration data

    Spectral powers of acoustic signals (in V^2/s) produced by tongue-palate interactions during consumption of various foods in the bands 60-300Hz and 400-2000Hz.

    Measured: between 2s and 20s after consumption of each sip

  2. Ratios of powers in segments of time-frequency transferred vibration data

    Ratios of spectral powers in the 400-2000Hz band over powers in the 60-300Hz band of acoustic signals produced by tongue-palate interactions during consumption of various foods (unit-free).

    Measured: 2-20 seconds after consumption of each sip

Secondary outcomes (6)
  1. Reported rating of product thickness

    Evaluation of product thickness on a Visual Analogue Scale (mm distance from the lower anchor)

    Measured: 0-2 sec after consumption of each sip

  2. Relative fat content in the collected tongue coating

    percentage of fat encountered in tongue coating that was collected with a swab immediately after consumption

    Measured: 2-20 sec after consumption of each sip

  3. Reported rating of product Creaminess

    Evaluation of product creaminess on a Visual Analogue Scale (mm distance from the lower anchor)

    Measured: 0-2 sec after consumption of each sip

  4. Reported rating of product Roughness

    Evaluation of product roughness on a Visual Analogue Scale (mm distance from the lower anchor)

    Measured: 0-2 sec after consumption of each sip

  5. Relative sugar content in the collected tongue coating

    percentage of sugars encountered in tongue coating that was collected with a swab immediately after consumption

    Measured: 2-20 seconds after bite consumption

  6. Relative protein content in the collected tongue coating

    percentage of protein encountered in tongue coating that was collected with a swab immediately after consumption

    Measured: 2-20 seconds after bite consumption

Questions about this trial

What is this clinical trial studying?

An observational study of Mouth Feel in Relation to Food Preference and Energy Intake, run by NIZO Food Research at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Powers in segments of time-frequency transferred vibration data (time frame: between 2s and 20s after consumption of each sip). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2017.
