Area of Science:

• Biotechnology
• Materials Science
• Food Science

Background:

• Innovative food system changes are necessary.
• Cultivated meat offers a sustainable alternative to traditional animal protein production.
• Developing safe and effective scaffolds is crucial for cultivated meat technology.

Purpose of the Study:

• To evaluate the use of whey protein isolate (WPI) and beta-lactoglobulin (β-LG) in hydrogel scaffolds for cultivated meat.
• To assess the impact of these proteins on scaffold properties and cell proliferation.
• To determine the suitability of WPI and β-LG as food-grade components for edible cultivated meat scaffolds.

Main Methods:

• Hydrogel scaffolds were formulated using alginate, WPI, and β-LG.
• Mechanical properties (stiffness, strength) of the scaffolds were analyzed.
• Cell proliferation was measured on modified scaffolds compared to controls.

Main Results:

• Alginate concentration and protein addition significantly altered scaffold stiffness and strength.
• Scaffolds incorporating WPI and β-LG demonstrated enhanced cell proliferation.
• The novel scaffolds showed innocuous properties, suitable for food applications.

Conclusions:

• WPI and β-LG are promising food-grade components for cultivated meat scaffolds.
• Modified hydrogels support and enhance cell growth, crucial for cultivated meat production.
• This research paves the way for advanced, edible scaffolds in cultivated meat development.
