As the demand for vegetarian and clean-label food ingredients rises globally, traditional animal-derived enzymes like rennin are increasingly being replaced with plant-based alternatives. Vegetable rennin, a coagulating enzyme sourced from plants such as thistles, nettles, or figs, is gaining significant traction in the global food and dairy processing sectors. Once a niche ingredient, it is now experiencing rapid adoption due to changing dietary preferences, religious constraints, and the booming vegan and vegetarian populations.
In this blog, we delve into the evolving dynamics of the vegetable rennin segment, highlighting the factors driving its demand, recent innovations, and regional variations shaping its future trajectory.
According to Marketintelo, “The global Vegetable Rennin Market size was valued at approximately USD 765 million in 2024 and is projected to reach USD 1,243 million by 2032, growing at a compound annual growth rate (CAGR) of 6.3% during the forecast period 2024–2032.”

What Is Vegetable Rennin?
Vegetable rennin refers to a group of enzymes derived from plant sources used primarily in cheese manufacturing. Unlike traditional animal rennet, which is extracted from the stomach lining of young ruminants like calves, vegetable rennin is obtained from plants like cardoon (Cynara cardunculus), fig latex, and certain fungi.
These plant-based enzymes replicate the function of chymosin, the active ingredient in animal rennet, making them effective in curdling milk during cheese production. Their vegetarian-friendly profile makes them particularly appealing to consumers who avoid animal products due to ethical, religious, or health reasons.
Factors Fueling Demand for Plant-Based Rennin
1. Rising Vegetarian and Vegan Populations
The global shift towards plant-based diets has intensified in recent years, with more individuals opting for vegetarian or vegan lifestyles. This cultural transformation is pushing food manufacturers to adopt non-animal-derived ingredients to cater to this growing consumer base. As a result, vegetable rennin is becoming the preferred coagulant in both artisanal and commercial cheese production.
2. Religious and Ethical Considerations
In regions where religious dietary restrictions prohibit animal-based enzymes, vegetable rennin provides a viable alternative. For example, in Hindu and Jain communities, where animal slaughter is generally frowned upon, plant-based rennin is an acceptable substitute. Similarly, Halal and Kosher certifications are easier to obtain with non-animal enzymes.
3. Clean-Label and Natural Ingredient Trends
Today’s consumers are scrutinizing food labels more than ever. Clean-label products with minimal, recognizable, and ethically sourced ingredients are in demand. Vegetable rennin, being plant-derived and minimally processed, fits squarely within this category, further elevating its adoption.
Regional Insights and Market Share Distribution
As per Dataintelo’s analysis, “The regional distribution of the Vegetable Rennin Market reflects varying consumer preferences, market shares, and growth rates. For instance, Europe accounted for approximately 42% of the market share in 2024, generating close to USD 321 million.”

Europe’s dominance is largely attributed to its strong artisanal cheese traditions and higher proportion of vegetarian consumers. Countries such as Spain, France, and Italy are actively embracing plant-based rennin, especially in premium cheese segments. North America follows, driven by consumer awareness and the booming vegan movement in the U.S. and Canada.
Meanwhile, emerging markets in Asia-Pacific and Latin America are slowly integrating plant-based enzymes into local food processing industries, though animal-derived rennet remains prevalent in several regions.
Application Scope: Beyond Cheese
While cheese production remains the primary application of vegetable rennin, the enzyme is also being explored in:
Dairy desserts such as panna cotta and custards
Milk fermentation processes in probiotic beverages
Food experimentation in plant-based yogurt and alternative dairy products
This expanding use case is further reinforcing its role in the broader dairy and functional food segments.
Technological Advancements and R&D Initiatives
Recent innovations in biotechnology and food engineering have led to the isolation of more effective and stable plant-based rennin enzymes. Researchers are now able to fine-tune enzyme activity levels for optimal performance across different milk types—cow, goat, sheep, or plant-based milk.
Startups and university-led food science programs are also exploring hybrid rennin formulations by combining plant-based enzymes with microbial cultures to achieve better curdling efficiency and flavor retention in cheese.
Sustainability Edge of Plant-Based Rennin
Vegetable rennin scores high on sustainability metrics when compared to animal-derived alternatives. It requires fewer resources—land, water, and energy—to produce and eliminates the need for animal slaughter. As climate change and ethical sourcing take center stage in consumer decision-making, the sustainability benefits of plant-based ingredients like vegetable rennin are likely to attract greater investment and attention from producers and policymakers.
Regulatory Support and Certifications
Governments and food authorities in many countries are updating their regulations to accommodate and encourage the use of plant-based ingredients in food manufacturing. Vegetable rennin has received approvals from major bodies including the U.S. Food and Drug Administration (FDA), the European Food Safety Authority (EFSA), and the Food Safety and Standards Authority of India (FSSAI).
Manufacturers that use vegetable rennin often leverage this compliance to obtain certifications like:
Vegan Certified
Kosher and Halal
Non-GMO Project Verified
Such labels help brands communicate their values clearly to their target audience and enhance consumer trust.
Challenges to Widespread Adoption
Despite its benefits, vegetable rennin does face some challenges:
1. Cost and Supply Limitations
Plant-based enzymes can be costlier to extract and stabilize compared to traditional animal rennet, especially when derived from rare botanical sources. This may affect affordability for small-scale cheese producers.
2. Functional Differences
Some cheese artisans argue that animal rennet yields better flavor profiles in aged cheeses like Parmigiano-Reggiano or Roquefort. While advances are being made to narrow this gap, there remains a segment of the market hesitant to switch fully to plant-based rennin.
3. Regional Availability
Vegetable rennin is not equally available in all global markets. Infrastructure, awareness, and supply chain limitations may slow down adoption in developing countries.
The Road Ahead: What to Expect
Looking forward, the vegetable rennin segment is poised for continued growth as consumer demand for clean-label, ethical, and sustainable food ingredients intensifies. Collaborations between food tech firms and traditional cheese manufacturers could play a pivotal role in standardizing and scaling the use of plant-based rennin across different types of cheese and dairy alternatives.
Furthermore, with increasing investment in plant-based food systems and ongoing innovation in enzyme technologies, vegetable rennin is expected to become a staple in mainstream food production.
Final Thoughts
Vegetable rennin is no longer just a niche substitute for animal rennet—it is becoming an essential tool in sustainable, ethical, and inclusive food manufacturing. As it continues to penetrate global markets and diversify its applications, its role in the future of food production is undeniably significant.
From meeting dietary needs to aligning with environmental goals, vegetable rennin represents a vital step toward a more conscious and flexible food industry.
