An Investigation of the Status of Commercial Meat Analogs and Their Ingredients: Worldwide and South Korea.

Meat analogs are a burgeoning industry, with plant-based meat analogs, insect-based meat analogs, algae-based meat analogs, mycoprotein-based meat analogs, and cell-based meat analogs. However, despite the industry's growth potential, market expansion faces hurdles due to taste and quality disparities compared to traditional meats. The composition and characteristics of meat analogs currently available in the market are analyzed in this study to inform the development of future products in this sector. The results show that plant-based meat analogs are mainly based on soy protein together with wheat gluten and methylcellulose or spices. Insect-based meat analogs tend to contain processed larvae as the protein source. Seaweed or spirulina is often the main ingredient in algae-based meat analogs. Mycoprotein-based meat analogs all use mycoproteins. Cell-based beef, pork, chicken, and seafood products are already under various stages of development around the world, although many are still at the prototype level.
