Introduction
Pea starch is a carbohydrate extracted from yellow peas. Yellow peas, or Pisum sativum, have been cultivated for thousands of years around the world. While peas have long been an important food crop, it is only recently that pea starch has emerged as a versatile plant-based ingredient widely used in food products.
What is Pea Starch?
Pea starch is the carbohydrate powder extracted from yellow peas. Pea starch granules are similar in size and shape to corn and potato starch granules. To produce pea starch, yellow peas are sorted, cleaned, cooked, and pressed to extract the starch from the peas. The starch is then washed, dried, milled into a fine powder, and packaged. Pure pea starch is a white or off-white powder that does not carry the taste or odor of peas.
Properties of Pea Starch
Pea Starchhas properties that make it functional across many applications. Some key properties include:
- Highly digestible - Pea starch is considered highly digestible for humans. This property makes it suitable for foods where high digestibility is important.
- Neutral flavor - Unlike other plant-based starches like corn or potato, pea starch does not impart its own flavor to foods. This allows other flavors to shine through.
- Texturizing ability - When heated in the presence of water or other liquids, pea starch granules swell and undergo gelatinization to produce a smooth texture. This property allows it to function as a viscosifier, emulsifier, thickener or gelling agent in foods.
- Gluten-free - Pea starch is naturally gluten-free, making it a suitable ingredient for people on gluten-free diets.
Uses of Pea Starch in Foods
The unique functional properties of pea starch have made it a popular ingredient in many commercial food applications, often replacing corn or potato starch. Some key uses of pea starch in foods include:
- Sauces and gravies - Pea starch is often used to thicken sauces and gravies, providing a creamy mouthfeel without much taste.
- Soups and dressings - As an emulsifier and thickener, pea starch helps maintain homogeneity and texture in products like soup bases, salad dressings and mayonnaise.
- Bakery products - Pea starch improves tenderness, shelf life and volume in baked goods like breads, cakes, cookies and pastries. It can partially or fully replace wheat flour.
- Processed foods - Many packaged or frozen foods like meat patties, fish sticks, pasta dishes and breakfast cereals contain pea starch as a binder or anti-caking agent.
- Noodles and pasta - High-protein, gluten-free noodles and pasta are commercially produced using a blend of pea protein and pea starch.
- Snack foods - Potato chips, corn chips, cheese crackers and nuts are coated with pea starch for crisp texture, lower fat content and to prevent clumping.
Benefits of Using Pea Starch
Compared to other starches, pea starch offers several advantages that are driving its increasing popularity and use:
Sustainability
- Peas have low environmental impact and require less water, fertilizer and pesticides than many other crops like corn or wheat. Pea starch production is more sustainable.
Health and Wellness
- Pea starch is naturally free of allergens like gluten, ensuring safety for people with gluten intolerance or celiac disease.
- Its high digestibility profile can help support digestive health.
- Pea starch is a source of dietary fiber and essential nutrients like vitamins, minerals and antioxidants that are retained from the whole peas.
Versatility
- Pea starch performs equally well or better than other starches across many applications. It can be easily substituted to replace corn or potato starches.
- Its neutral taste allows for formulation flexibility withoutImpact on product taste.
Cost Effectiveness
- Pea crops yield more starch per acre than corn or wheat. Coupled with the rising domestic demand, pea starch is very cost competitive globally.
With the growing preference for plant-based, sustainable and healthy ingredients, pea starch is emerging as a top choice. Its versatile functional properties and nutritional profile have led to widespread adoption of pea starch across the food industry. As production increases to meet demand, pea starch looks poised to play a leading role as a key plant-based ingredient of the future.
