Overview
With the growth of global meat consumption and increasing consumer requirements for food safety and quality, the application of glutamine transaminase in meat processing continues to expand. Applications such as restructured meat, emulsified sausages, and imitation meat products are in strong demand.
With the increasing popularity of vegan and plant-based foods, the demand for quality improvement of plant protein products is growing. Glutamine transaminase significantly improves the gelation, elasticity, and taste of plant proteins, making it an indispensable enzyme preparation in plant-based meat products and soy product processing.
Consumer demand for natural, additive-free, clean label foods is growing. TG enzyme, as a food industry enzyme preparation that acts as a catalyst during processing with negligible residual enzyme in the final product, aligns with clean label consumption trends.
