Production of alternative (protein) products demands precise control over ingredient hydration, structure development, and temperature, while protecting sensitive functional components and ensuring hygienic, allergen-safe processing. Continuous mixing enables consistent product quality at industrial scale, reducing processing time, and allowing faster cleaning compared to traditional batch methods.
Alternative products include plant-based meat substitutes, gluten-free doughs, and other non-traditional formulations designed to meet dietary, ethical, or environmental preferences. These products often exclude conventional structuring agents like gluten or animal-based proteins, and instead rely on novel plant proteins, hydrocolloids, and starch systems to replicate texture, taste, and functionality.
In industrial food production, mixing is a critical phase in the preparation of alternative (protein) products. It ensures even hydration, structural development, and functional activation of ingredients. The mixing process must deliver consistent results despite widely varying ingredient behaviour. Mixing systems must handle challenging rheology, ensure dispersion of powders, and avoid premature gelling or denaturation.
Alternative formulations typically involve functional ingredients like isolated plant proteins, hydrocolloids, fibers, or modified starches. These components are often more sensitive to shear and hydration than traditional wheat flour or meat proteins, requiring precise dosing and uniform dispersion during mixing.
Gluten-free and meat-alternative doughs may have slow or uneven water uptake. Some ingredients absorb gradually; others may resist hydration or clump when added too quickly. Continuous mixing helps by hydrating ingredients inline under controlled shear and timing, producing a consistent, cohesive mass.
Unlike traditional doughs, optimal mixing here is less about gluten development and more about achieving dispersion, hydration, and matrix formation without breakdown. specific mechanical energy (SME) is a valuable metric to define mixing boundaries that preserve texture and product integrity.
Many functional ingredients in alternative formulations are thermosensitive. For example, methylcellulose gels upon heating, and some proteins denature above 40–45 °C. Excess mixing energy can cause early gelling or phase separation. Industrial mixers must therefore maintain process temperatures (typically 18–28 °C) within narrow, product-specific ranges.
Without gluten or muscle fibers, structure must be built through controlled shear, binding, and thermal management. Mixing creates alignment and bonding in protein-starch matrices or emulsified fats that simulate bite, chewiness, or elasticity, especially in meat analogues. Overmixing destroys structure; undermixing can leave the product crumbly or dry.
Each alternative application has its own unique processing requirements. At Sobatech, we understand that a one-size-fits-all approach does not work in industrial mixing. That is why our continuous mixing systems are tailored to the specific needs of each product type.
