Furthermore, consumers’ increasing inclination toward plant-based foods is expected to generate growth opportunities for the players operating in the alternative protein market.

Alternative Protein Market Growth Drivers

Increasing Venture Investments Driving the Growth of the Alternative Protein Market

Well-established meat and dairy product manufacturers are being targeted by civil society groups and new food businesses due to ethical and animal welfare concerns. Plant-based products, including protein, are animal cruelty-free and, therefore, ethical and more sustainable. Protein diversification has the potential to transform food companies’ core business and value proposition due to its higher profitability, lower risk exposure, and the ability to compete and innovate.

The growing trend of millennials adopting flexitarian and meat-free diets indicates a change in consumption habits, a significant shift from earlier generations. Companies across the food value chain, from producers to retailers, are already investing in these opportunities. Some companies are hedging against or preparing for a decline in the demand for animal products and investing in companies that produce plant-based alternatives. In the past few years, market players have received investments/funding from several high-profile individuals, financial investors, and companies. According to the Good Food Institute, In 2024, the alternative protein industry received USD 2.9 billion in disclosed investments. In the same year, plant-based meat, egg, and dairy companies received USD 1.9 billion in investments, a significant increase over USD 693 million raised in 2019. Plant-based meat, seafood, egg, and dairy companies have raised USD 6.3 billion in investments since 2010.

Some of the recent key developments in this market are as follows:

• As of September 2022, InnovaFeed SAS (France) had raised USD 250.0 million in Series D funding to increase its Black Soldier Fly (BSF) production capacity.
• As of March 2022, Australia had invested USD 262.6 million (AUD 378.0 million) in transforming South Australia into a plant-based protein manufacturing powerhouse. Three new production plants will be constructed using the investment to supply to domestic and international partners. The entire project falls under the AUD 1.3 billion Modern Manufacturing Initiative.
• In April 2021, Archer-Daniels-Midland Company (ADM) (U.S.) opened a new cutting-edge, plant-based innovation lab in the company’s Biopolis Research Hub in Singapore. This lab was designed to develop next-level, on-trend, and nutritious products to meet the growing demand for food & beverage products in Asia-Pacific.

Thus, increasing venture capital investments supporting plant-based product manufacturers is driving the growth of the global alternative protein market.

Innovations in Food Technologies Supporting the Growth of the Alternative Protein Market

Alternative protein are increasingly becoming a staple in modern-day diets. Consumer demand for ethical, sustainable, and healthy protein sources is driving investments and innovation in the meat and dairy substitutes industry. Innovative food is a category of agrifood tech encompassing novel food products and ingredients, such as alternative meat (plant-based and cell-culture-based), insect protein, alternative sugars, and flavor enhancers. According to the venture capital firm AgFunder, global investments in food tech and agtech start-ups reached USD 29.6 billion in 2022, wherein the food innovation sector accounted for a ~ 60% share. The category is dominated by animal-free alternative meat and dairy products and healthy ingredient alternatives.

Advances in alternative protein-based products are generating a great deal of interest among consumers and mainstream news. They are becoming increasingly common in retail outlets and foodservice menus. Animal agriculture is inherently inefficient, particularly in terms of feed conversion. According to the World Resources Institute (WRI), even the most efficient source of meat – chicken – converts only around 11% of gross feed energy into animal protein (WRI 2016). Innovations in food technologies have enabled the production of various alternative protein, ranging from advanced plant-based protein to cultured meat products without animals.

Thus, the food technology revolution is expected to fundamentally disrupt the current market and make protein more sustainable, supporting the growth of the alternative protein market.

Alternative Protein Market Growth Opportunity

Consumers’ Increasing Inclination Toward Plant-Based Diets Positively Influencing the Demand for Alternative Protein

In recent years, there has been a significant growth in vegetarianism and veganism globally due to increasing health and environmental awareness and compassion for animals. In 2021, ~8% of the world's population was vegetarian (Source: Heinrich Böll Stiftung). In the U.S., around 5–8% of people were vegan in 2022. Also, 31–42% of India's population is considered vegetarian. In Europe, vegans account for ~5% and vegetarians for ~10% of the total population. According to the Vegan Society, in 2022, ~10% of the U.K.’s population followed a vegan diet, and 9% of the population in Germany was vegetarian.

Veganism refers to the practice of refraining from using eggs, dairy, meat, and other animal-derived products. Vegans consume products that contain ingredients or components derived from plant sources. Increasing health concerns and allergic reactions to egg and dairy products have shifted consumers’ focus toward veganism. Additionally, consumers believe that veganism can help reduce the risk of chronic diseases such as heart disease and cancer. Increasing concerns regarding animal welfare and the environment have also encouraged many consumers to choose vegan foods. This growth in veganism has boosted the demand for plant-based products such as pea protein, soy protein, and flaxseeds.

According to the Academy of Nutrition and Dietetics, suitably planned vegetarian, including vegan diets, are healthful and nutritionally acceptable. They decrease the danger of certain ailments, including ischemic heart disease, Type 2 diabetes, hypertension, certain types of cancer, and obesity. These diets are suitable for all lifecycle stages, including pregnancy, lactation, infancy, childhood, adolescence, and older adulthood, as well as for athletes. Thus, increasing veganism is generating significant growth opportunities for the players operating in the alternative protein market.
