As more people look for healthier, ethical, and sustainable food options, plant-based protein has become very important for food, drink, and supplement makers. If you are making a new product or buying ingredients for one you already have, it can feel overwhelming. We are here to help you understand the key points. This way, you can successfully buy plant-based proteins for your business.

What Is a Plant-Based Protein?

Plant-based protein comes from plants such as beans, grains, seeds, and nuts. Unlike animal proteins, these sources are more sustainable. They are suitable for vegan, vegetarian, and natural products. Some common types include pea protein, soy protein, rice protein, and hemp protein. For a full list we advise you to review our proteins page.

Why Plant-Based Options?

B2B buyers and food producers are looking for vegetarian protein options and vegan protein sources because:

  • Sustainability: Lower carbon footprint and less water-intensive production.
  • Market demand: Rise of vegan, flexitarian, and allergen-conscious consumers.
  • Labeling advantages: Free-from claims (e.g. lactose-free, non-GMO, allergen-friendly).

By teaming up with suppliers that focus on plant-based protein, food brands can meet changing consumer demands and strengthen their supply chain.

Important Types of Plant-Based Proteins

The most traded and requested plant-based proteins in B2B sourcing include:

  • Pea Protein: Highly digestible and neutral in flavor, used in beverages, meat analogues, and sports nutrition.
  • Soy Protein: One of the most complete plant proteins, suitable for dairy alternatives and baked goods.
  • Rice Protein: Hypoallergenic and ideal for sensitive formulations.
  • Faba Bean Protein: High in protein and starch, with growing popularity in snacks and vegan meats.
  • Pumpkin and Sunflower Protein: Oilseed-derived and rich in micronutrients, used in bakery and health food products.
  • Hemp Protein: Known for its omega-3 content and used in shakes and bars.
  • Chickpea, Flaxseed, Oat, and Lupin Protein: Functional and nutritious additions to plant-based blends.

Advantages and Disadvantages

Plant Protein Benefits

Plant-based proteins have important advantages for food makers. They do not contain dairy, making them safe for people who are lactose intolerant or have dairy allergies. Additionally, many plant proteins are more sustainable than animal-based ones. They use less water and land. According to a report by MarketsandMarkets, the global plant-based protein market is projected to grow from USD 14.3 billion in 2024 to USD 20.5 billion by 2029.

Plant Protein Disadvantages

Plant proteins have some challenges. An important issue is that many plant-based proteins do not have all the essential amino acids, so they are not complete protein sources on their own. To solve this, manufacturers often mix different plant proteins together. Another challenge is how well our bodies can digest these proteins. Some plant proteins have antinutrients that can affect how our bodies absorb nutrients. To make plant proteins easier to digest and to help our bodies use them better, methods like fermentation and sprouting are commonly used.

Plant-Based vs Whey Protein

Whey protein is a mainstay in sports and clinical nutrition because it absorbs quickly and has a full range of amino acids. However, plant-based protein is becoming more popular as brands focus on vegan, allergen-free, and sustainable choices.

Plant proteins such as pea, soy, and rice can perform similarly to whey when mixed or separated correctly. While whey dissolves better and has more leucine, many new plant-based options are improving in texture and function.

For many business buyers, the choice depends on what consumers want, regulatory requirements, and how products are labeled.

Important considerations:

  • Whey: Fast-digesting, dairy-based, not suitable for vegan or lactose-free claims.
  • Plant-based: Supports natural, vegan, and allergen-sensitive formulations.
  • Logistics: Plant proteins offer more sourcing flexibility and are less tied to dairy markets.

Best Plant-Based Protein Source

Soy and pea proteins are the most popular choices for plant-based protein powders. They are well-researched and considered good options. Soy protein is a complete protein, so it contains all the essential amino acids. However, some people have concerns about GMOs and soy allergies. Because of this, many brands choose pea protein instead. Pea protein is easy to digest, has a good amino acid profile, and can be used in many food and drink products.

For brands looking to create best-tasting vegan protein powders, blending different sources (e.g., pea and rice) helps improve both flavor and amino acid completeness.

Frequently Asked Questions (FAQ)
