Optimization of mixing ratio for a TVP-based alternative sausage using mixture experimental design

Area of Science:

• Food Science
• Materials Science

Background:

• Plant-based meat alternatives are gaining popularity.
• Textured vegetable protein (TVP) is a common ingredient in meat substitutes.
• Optimizing TVP blends is crucial for achieving desirable product characteristics.

Purpose of the Study:

• To determine the optimal blending ratio of TVP for plant-based sausages.
• To evaluate the impact of TVP, oil, and ice content on sausage physicochemical properties.

Main Methods:

• A mixture design approach was used for sausage formulation.
• Physicochemical properties including texture, water holding capacity, and digestibility were measured.
• Statistical analysis was employed to identify optimal ingredient ratios.

Main Results:

• Increased TVP content positively correlated with hardness, chewiness, and protein digestibility.
• Higher oil content led to decreased hardness and improved texture.
• The optimal blend was determined to be 44.19% TVP, 7.59% oil, and 28.28% ice for desirable sausage characteristics.

Conclusions:

• The study successfully established an optimal blending ratio for plant-based sausages using TVP.
• These findings provide valuable data for the development and quality control of plant-based meat alternatives.
• Understanding ingredient interactions is key to producing high-quality meat substitutes.
