Efficacy and Tolerability of a Specialized Food Products for Dietary Therapeutic and Preventive Nutrition Based on Ice Cream (Ice Cream With Brazzein, Maltitol and Oligofructose; Ice Cream With Brazzein, Erythritol, Maltitol and Inulin) Compared to Standard (Sundae) Ice Cream

December 11, 2025 updated by: Federal State Budgetary Scientific Institution "Federal Research Centre of Nutrition, Biotechnology
This is a double-blind, randomized, comparative controlled cross-over study of efficacy and tolerability of 2 specialized food products based on ice cream compared to the standard (sundae) ice cream for patients with non-alcoholic fatty liver disease with or without type 2 diabetes mellitus. On 3 consecutive days eligible subjects will receive a portion of specialized food products with breakfast (ice cream with brazzein, maltitol and oligofructose; ice cream with brazzein, erythritol, maltitol and inulin; standard ice cream (sundae)) followed by the standard ration. Tolerability will be assessed based on specialized scales and formal questioning. Glucose monitoring will be performed with the use of prolonged blood glucose monitoring system (FreeStyle Libre 2, Abbott Diabetes Care, USA)

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

An organoleptic evaluation study phase preceded the main active intervention phase of the study. During this phase, all three types of ice cream were evaluated using a 5-point hedonic scale (1 = dislike extremely, 3 = neither like nor dislike, 5 = like extremely) for overall impression, flavor, color, appearance, aroma, and texture. Portions of 100 g of the ice cream were used with proper labelling (three-digit code) for randomization and supporting crossover design. The evaluation was performed as one portion per day and organized due to technical reasons as two round evaluations, in which one round included standard ice cream and the 1st special product, and the second round included standard ice cream and the 2nd special product. There were 3 days washout period between rounds to prevent carryover effects between the tested products. The percentage of ice cream consumed was determined by weighing the remaining portion of each ice cream after testing.

Phase

Phase
