UFV's LIPA Lab Achieves Milestone with Pequi Protein Breakthrough

The Laboratório de Inovação em Processos e Análise (LIPA) at Universidade Federal de Viçosa (UFV) has marked a significant achievement in Brazilian food science research. Researcher Fábio Ribeiro dos Santos, a PhD candidate in the Department of Food Technology, has published a groundbreaking study in Food Hydrocolloids, one of the world's leading journals in the field. This publication underscores UFV's growing prominence in sustainable food innovation, particularly leveraging native Brazilian resources like pequi fruit.

Pequi (Caryocar brasiliense Camb.), a nutrient-rich fruit from Brazil's Cerrado biome, holds untapped potential as a plant-based protein source. Fábio's work explores how high-pressure homogenization (HPH)—a non-thermal processing technique—transforms pequi proteins under acidic and alkaline conditions, enhancing their solubility and colloidal stability for advanced food applications.

Spotlight on Fábio Ribeiro dos Santos and LIPA's Expertise

Fábio Ribeiro dos Santos graduated in Food Engineering from Universidade Federal de Minas Gerais (UFMG) and is pursuing his master's and PhD in Food Science and Technology at UFV's Department of Food Technology (DTA). As a key member of LIPA, he contributes to cutting-edge research on food processing innovations, including protein structuring and bioactive compound extraction.

LIPA, housed within DTA at UFV, focuses on innovative processes like HPH, ultrasound, and extrusion to develop sustainable food ingredients. The lab's multidisciplinary approach bridges academia and industry, training the next generation of food scientists. For aspiring researchers, opportunities abound at higher-ed-jobs in Brazil's vibrant food tech sector.

Food Hydrocolloids: A Premier Venue for Food Science Excellence

Food Hydrocolloids boasts an impact factor of 12.4 (2025), ranking A1-Q1 and recognized as the top journal for research articles in hydrocolloids and food structuring. Published by Elsevier, it attracts global submissions on polysaccharides, proteins, and gels critical for modern foods like plant-based meats and dairy alternatives.

Fábio's paper stands out amid rigorous peer review, highlighting Brazil's rising influence in international food science. UFV's consistent publications here reflect its status as a leader in agribusiness education.

Pequi: Brazil's Underexploited Superfruit and Protein Powerhouse

Pequi, native to the Cerrado, is packed with proteins, vitamins, and antioxidants, making it ideal for functional foods. Traditionally used in regional dishes, its proteins are underutilized due to poor solubility and stability. Brazil, the world's top soy producer, seeks diverse plant proteins amid sustainability demands.

Fábio's research addresses this by isolating pequi proteins and subjecting them to HPH, revealing conformational changes that boost techno-functional properties. This aligns with national efforts to valorize biodiversity for food security.

High-Pressure Homogenization: Revolutionizing Protein Processing Step-by-Step

HPH forces proteins through narrow gaps at 100-400 MPa, causing shear, cavitation, and turbulence. Here's how it works:

• Step 1: Protein dispersion in acidic (pH 3) or alkaline (pH 11) media.
• Step 2: Multiple HPH passes unfold proteins, exposing hydrophobic regions.
• Step 3: Reassembly into stable nanostructures with improved solubility.
• Step 4: Assessment via spectroscopy, microscopy, and rheology.

Fábio's study correlates these changes to enhanced colloidal stability, vital for emulsions and gels.

Key Findings: Controlled Structural Reorganizations Unlock Potential

The research demonstrates HPH induces targeted protein unfolding and refolding. Under acidic conditions, fibrils form with high solubility; alkaline treatments yield aggregates with superior emulsion stability. Spectroscopic data (FTIR, fluorescence) pinpointed β-sheet transitions, while microscopy visualized nanostructures.

These insights explain pequi proteins' behavior, outperforming native forms in food matrices. No emojis here, but the results promise cleaner-label ingredients without chemical additives.

Implications for Brazil's Food Industry and Plant-Based Innovation

Brazil's food sector, valued at billions, eyes plant proteins for vegan products and meat analogs. Pequi proteins could replace imports, reducing costs and carbon footprints. HPH enables scalable production, fitting agro-industries in Minas Gerais.

Stakeholders praise the work: industry for functionality, sustainability experts for biodiversity use. UFV's tech transfer boosts local economies.

Sustainability Angle: Valorizing Cerrado Biodiversity

The Cerrado supplies 30% of Brazil's water and hosts pequi, threatened by deforestation. Fábio's study promotes agroforestry, creating value chains. Proteins from pequi by-products minimize waste, aligning with UN SDGs.

Government reports highlight native fruits' role in food security. LIPA's efforts position UFV as a sustainability hub.
