Trial summary

There are different types of casein on the market, which differ according to their chemical or physical process of obtaining. The processes will impact structural differences in the macromolecular assembly. The majority of caseins marketed in nutrition are casein in the form of Na caseinate or Ca caseinate.

About this study

There are different types of casein on the market, which differ according to their chemical or physical process of obtaining. The processes will impact structural differences in the macromolecular assembly.

The majority of caseins marketed in nutrition are casein in the form of Na caseinate or Ca caseinate.

The micellar caseins obtained by membrane filtration (physical process) are more and more used in the nutrition market.

The development of casein extraction with different structures on an industrial scale opens up other perspectives for these proteins, particularly in terms of health.

The main objective of this project is to study the postprandial kinetics of the plasma concentrations of the essential amino acids of three structurally different types of caseins.

The secondary objective is to study the speed of gastric emptying and the nutritional properties of different proteins.

Read the detailed description

All the participants will give freely their written informed consent before their selection in the study.

Each subject will participate in 3 kinetics of 5 hours with a different product test each time, in a randomized order. A wash-out period of at least 7 days will be respected between each kinetics. The products to be tested will be in the form of a powder (25g individual sachet, including 20.1g of protein) which will be reconstituted in 250ml of water and to which 100mg of 13C sodium acetate will be added.

For each of the kinetics, blood samples, expires gasses, will be collected at different time during the kinetics. A urinary collection throughout the day of kinetics will also be performed to allow the determination of urinary nitrogen Indirect calorimetry measurements will be performed 45 minutes every hour in the postprandial period and a measurement of 45 minutes will be made when the subject is fasting. Six measurements of indirect calorimetry will be performed for each kinetic.

Finally subjects will be asked to evaluate their satiety on a visual analog scale, 15' before taking the product, then every 15' the first hour in the postprandial period and every 30 'from the 2nd hour.

The subjects will also have a tolerance questionnaire to complete with each kinetic.

At the end of the kinetics, a standardized meal, single menu, consumption ad libitum measured in double weighing will be proposed to the volunteers to evaluate their satiety

During the 3 days preceding each kinetics, the protein intake of the subjects will be controlled. The meal of each night in the evening of kinetics will be standardized and identical for each kinetics. The volunteers will complete a food survey on the 3 days of control of their diet that precede each kinetics.

What is being measured

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

  1. Changes in the plasma concentrations of the essential amino acids of 3 structurally different types of caseins during postprandial kinetics

    Maximum total plasma concentration of the essential amino acids measured during different points of the 5 hours of the kinetics (one kinetic / type of casein). One point before (basal) and several points (15, 30, 45, 60, 90, 120, 150, 180, 210, 240, 270, 300 minutes) after the consumption of one of the 3 types of caseins

    Measured: before and during 300 minutes after product consumption

Secondary outcomes (8)
  1. Maximum plasma concentration for non essential amino acids

    Maximum total plasma concentration of the non essential amino acids measured during different points of the 5 hours of the kinetics (one kinetic / type of casein). One point before (basal) and several points (15, 30, 45, 60, 90, 120, 150, 180, 210, 240, 270, 300 minutes) after the consumption of one of the 3 types of caseins

    Measured: before and during 300 minutes after product consumption

  2. Tmax

    Time in minutes to obtain the maximal total plasma concentration of essential amino acides

    Measured: before and during 300 minutes after product consumption

  3. Measurement of gastric emptying by the 13C sodium acetate method

    Time to obtain the maximum expired 13CO2 concentration (Tmax)

    Measured: before and during 300 minutes after product consumption

  4. gastric emptying at 50% (T 1/2)

    Obtaining time for gastric emptying at 50% (T 1/2)

    Measured: before and during 300 minutes after product consumption

  5. Thermogenic effect of proteins at different times of kinetics

    Oxidation of substrates (lipids, proteins, carbohydrates) (g/min) by indirect respiratory calorimetry corrected for nitrogen excretion.

    Measured: before and during 300 minutes after product consumption

  6. Satietogenic effect of proteins evaluated using a visual analogue scale at different times of kinetics

    Measured by a visual analogue scale 100mm in length with words anchored at each end, expressing the most positive and the most negative rating, were used to assess hunger, satiety, fullness, prospective food consumption.

    Measured: from product consumption until 300 minutes after

  7. Tolerance of products assessed by a questionnaire

    Measured: at 300 minutes after product consumption

  8. Changes in the plasma concentrations of insulin at different times of kinetics

    Measured: before and during 300 minutes after product consumption

Questions about this trial

What is this clinical trial studying?

A study testing native and non native casein in people with Protein Digestion, run by Ingredia S.A. at 1 site in France.

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 8 inclusion and 6 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 24 Feb 2020. 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 France. 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?

Changes in the plasma concentrations of the essential amino acids of 3 structurally different types of caseins during postprandial kinetics (time frame: before and during 300 minutes after product consumption). 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 24 Feb 2020.
