Savory omega-3 enriched plant protein prenatal drink

Overview

This functional beverage addresses a critical gap in prenatal nutrition by delivering high concentrations of omega-3 fatty acids (EPA and DHA) in a palatable, low-glycemic, high-protein drink. Low levels of DHA and EPA in pregnant women have been correlated with premature birth, yet compliance with omega-3 supplementation remains a major challenge. By combining plant proteins and resistant starch from cereals and pseudocereals with omega-3 through extrusion, the formulation transforms the unpleasant fishy flavor into a more pleasant sensory experience, significantly improving adherence among women of reproductive age. The beverage is designed to supplement prenatal diets, supporting overall health, nutritional well-being, and healthy fetal development while potentially reducing the risk of births before 37 weeks.

Technical specifications

• Extrusion-based encapsulation: During extrusion, endogenous fats and proteins from legumes interact with cereal starch to form complexes that act as a controlled release system for omega-3 lipids.
• Sensory optimization: Sensory evaluation with 100 untrained panelists in Mexico City using a hedonic scale (1 to 7) confirmed that combining plant proteins and resistant starch reduces the unpleasant flavor of fish oil.
• Bioactive lipid delivery: Gas chromatography analysis confirmed an encapsulating effect that protects omega-3 fatty acids through interaction with starch and proteins.
• Structural characterization: X-ray diffraction, Raman spectroscopy, and Fourier-transform infrared spectroscopy identified crystalline and amorphous structures responsible for the low glycemic index.
• Morphological analysis: Scanning electron microscopy revealed particle morphology differences, with amorphous samples displaying higher surface roughness and structural features associated with improved functionality.
• Nutritional profile: High protein content, low glycemic index, and concentrated EPA and DHA delivery in a single beverage format.

Technology readiness level

The complex ingredient has completed multiple validation stages including sensory evaluation, fatty acid profiling, structural characterization, and morphological analysis. A clinical protocol to validate the beneficial effects of the beverage in 120 Mexican adults has been approved (CONBIOÉTICA-09-CEI-011-2060627). This upcoming trial will assess blood chemistry, liver function, lipid profile, glutathione peroxidase, body composition, dual-energy X-ray absorptiometry, inflammation markers (TNF-alpha, IL-6, C-reactive protein), dietary intake, Diet Quality Index, gastrointestinal function, and gut microbiota changes at 0, 30, and 60 days of daily consumption. Results from this first stage will inform effective dosing, compliance, and formulation refinements before progressing to trials with obese or overweight pregnant women to confirm inflammation reduction and premature birth prevention potential.
