Plant-based foods continues to be a hot category as a result of the increase in new product launches. This is due to the advancements in procuring a variety of raw materials and creating new processing technologies. In addition, the escalating demand for plant-based products globally drives this growing trend as well. According to statistics cited on the Plant-based Food Association(PBFA) web page, plant-based foods grew by 27% in 2020 to reach a whopping $7B in the U.S.
The plant-based dairy segment leads this category reaching $2.5B in 2020 with an average growth of around 20% compared to the previous year according to the PBFA. And this segment includes products like ice cream and frozen novelties which also grew by 20% and generated about $435M in sales. For many manufacturers, this is the tip of the iceberg. For instance, this segment will grow exponentially as the demand for foods free from animals and their byproducts continues to boom.
Vegan Ice Cream Challenges
However, creating plant-based frozen desserts has its own set of challenges. For example, these products come in a variety of bases including almond milk, coconut milk, cashew milk, and oat milk to name a few. Many of these bases contain low protein and fat which typically helps bind water molecules during the freezing process. Because of this, ice crystals form which create a grainy or sandy mouthfeel in the finished product.
Some solutions include adding proteins, food gums and other hydrocolloids to bind the water during the freezing process. At the same time, many of these ingredients lack freeze/thaw stablility during handling and storage. As a result, water eventually migrates out of the food matrix, causing not only ice crystal formation, but also a gummy texture depending on the stabilizing agent used.
Natural, Creamy and Smooth Texture
One natural ingredient that remains amiss to formulators is citrus fiber. Yet not all citrus fibers are created the same. Citri-Fi, a highly functional citrus fiber created from byproduct of the citrus juicing process continues to be an ideal fit for this food application. The physical process creates the high surface area and emulsification properties that frozen desserts need. This high surface area in combination with the high pectin binds water and minimizes ice crystal formation during the freeze/thaw process. As a result, the frozen dessert provides a smooth and creamy mouthfeel without the gumminess over time.
Citri-Fi is typically used between0.25% to 1.50%. There are several incorporation methods available. Typically, Citri-Fi is mixed with the dry ingredients first before being added to the aqueous phase. However, adding Citri-Fi to glucose syrups first also gives formulators another option. And if Citri-Fi needs to be added to water first, it is recommended to add with strong agitation to prevent fisheyes from forming.
Another key trend includes upcycled or sustainable food ingredients. Citri-Fi citrus fiber checks off those boxes when it comes to a sustainable story from farm to fork. This natural citrus fiber is non-GMO Project Certified, gluten-free and allergen-free. Citri-Fi's labeling options include citrus fiber, dried citrus pulp or citrus flour which resonate well in the clean label markets. As a result, this natural citrus fiber benefits a variety of products such as plant-based, vegan or dairy-free ice creams and frozen novelties.
Looking into the Crystal Ball
As for future trends, new innovations will emerge within the plant-based ice cream arena. For instance, fermentation and other biological processes now create new proteins without involving an animal. Some vegan ice creams will be produced with new and novel plant-based milk bases. On the other hand, other products will focus on simple formulations to maintain a clean image. Regardless, Citri-Fi is an ideal solution to minimize ice crystal formation in any of these innovative technologies coming down the pipeline.
