Optimization of the Meat Flavoring Production Process for Plant-Based Products Using the Taguchi Method

Area of Science:

• Food Science and Technology
• Sensory Analysis
• Chemical Engineering

Background:

• Plant-based meat substitutes require improved flavor profiles to meet consumer expectations and reduce animal fat intake.
• The Maillard reaction is crucial for developing meat-like flavors, but its optimization in plant-based systems is challenging.

Purpose of the Study:

• To optimize the production of meat flavorings for plant-based products using the Taguchi method.
• To investigate the impact of sugar type, concentration, and reaction temperature on Maillard reaction products and sensory characteristics.

Main Methods:

• Employed the Taguchi method to systematically study the effects of sugar type (fructose, glucose, xylose), concentration (25-100 mM), and temperature (140-160 °C).
• Flavor precursors were heated using microwave technology (30 bar, 15 min).
• Analyzed Maillard reaction products, sensory characteristics, and volatile organic compounds (VOCs) using techniques including heat map visualization.

Main Results:

• Reaction temperature was the most significant factor influencing Maillard reaction products and sensory attributes.
• Optimal conditions identified: 25 mM xylose heated at 140 °C produced the most desirable meat flavor and highest consumer acceptability.
• VOC analysis confirmed the presence of characteristic meat flavor compounds (aldehydes, ketones, alcohols).

Conclusions:

• The Taguchi method effectively optimized the production of plant-based meat flavorings.
• Findings provide a pathway for developing more appealing and balanced odor profiles in plant-based meat alternatives.
• This research contributes to enhancing the sensory quality of plant-based diets.
