Exploring Cutting-Edge Technologies in Plant-Based Food Processing

Technological innovations like ohmic heating, shear cell tech, 3D printing, and electrospinning are transforming plant-based food processing, enabling authentic products with improved texture, flavour, and scalability.

FREMONT, CA: The landscape of food processing is changing as a result of the technical advances that have exploded in the plant-based food business in recent years. These most recent developments are revolutionising the way plant-based foods are made, opening up exciting possibilities for developing scrumptious, environmentally friendly, and nutritionally sound substitutes for conventional animal-based products. These cutting-edge technologies, which range from sophisticated extrusion procedures to advancements in 3D printing and unique processing techniques, are propelling the development of plant-based foods that closely resemble the flavour, texture, and look of their animal-derived counterparts.

Extrusion technology in food production allows plant-based producers to replicate meat and seafood texture, transforming the industry with innovative technologies like ohmic heating, shear-cell, 3D printing, and electrospinning.

Ohmic Heating

Ohmic heating is a highly effective technique employed in food processing, which involves the application of an alternating current to rapidly and uniformly elevate the temperature of food products. Widely utilized in the food industry, it serves as a reliable method for tasks such as sterilisation and pasteurisation of various food items. Due to its proven efficacy, Ohmic heating has found extensive applications in diverse food processing scenarios.

This process offers a significant advantage with its exceptional temperature control, making it an invaluable tool for processing plant-based proteins that are prone to denaturation and coagulation when subjected to conventional thermal processing techniques. Through the modification of structural and functional properties, ohmic heating enhances the overall functionality of plant-based proteins, thereby improving key properties like emulsification, gelation, and foaming characteristics. This ability to fine-tune the temperature and optimize protein properties underscores the value of ohmic heating in the processing of plant-based proteins.

Through the implementation of consistent heat distribution, ohmic heating effectively reduces the presence of antinutrients while simultaneously preserving the nutritional value and sensory attributes of alternative protein products. This innovative method optimizes the texture, mouthfeel, and flavour, culminating in an unparalleled culinary encounter that remains true to the authentic experience.

Shear Cell

By harnessing the power of shear technology, high pressure is applied to effectively disrupt cell walls in raw materials. This process leads to remarkable improvements in the texture, digestibility, nutritional composition, flavour, and shelf life of alternative protein products.

The implementation of shear cell technology brings forth a higher degree of accuracy and uniformity in the deformation of plant-based proteins. This precise manipulation enables the creation of fibrous meat substitutes that retain their stability and structural integrity even upon cooling. Constant advancements in this field, including the development of the Couette shear cell, are continuously pushing the boundaries of productivity and precision to elevate the overall efficiency of the process.

Electrospinning

Electrospinning, an innovative technology, is being actively investigated for its potential in advancing alternative proteins. This technique harnesses the power of an electric field to transform polymer or protein solutions/melts into nanofibers. These nanofibers play a crucial role in the development of plant-based food products that closely mimic the texture of meat and seafood derived from animals. By leveraging the customization and precision capabilities of electrospinning, researchers aim to create structures that are authentic to their original counterparts.

Technological advancements in plant-based food processing have revolutionized the industry, creating healthier, sustainable, and delicious alternatives to traditional animal products. Advanced protein extraction and purification techniques enable plant-based meat substitutes that mimic animal-based products' texture, taste, and nutritional profile. These innovations have improved flavour profiles, texture, and nutritional content, attracting a broader consumer base. Additionally, sustainable practices like precision farming, vertical farming, and hydroponics have reduced water usage, land footprint, and pesticide use.
