Record
The global challenge of feeding 10 billion people by 2050 amid climate change and crop diseases requires increasing food production by 50% over the next 25 years.
Previous research, including the World Resources Report, has identified several solutions, including reducing food demand growth, increasing production without expanding agricultural land, protecting ecosystems, boosting fish supplies and reducing agricultural gas emissions greenhouse.
Addressing these issues requires innovative technologies such as precision agriculture, genetic modifications and alternative protein sources.
However, the translation of these technological developments into commercial applications is crucial and is often spearheaded by start-ups and university spin-outs.
Despite significant efforts, a gap remains in the effective scaling of these innovations, particularly in the development and commercialization of alternative protein sources to meet the protein requirements due to the different dietary trends in low- and high-income populations.
This review focused on the latest developments and commercial application of alternative protein sources to address the challenge of food security.
An ecosystem of startups
This author, Elena Lurie-Luke of the Department of Life Sciences at Durham University, UK, used startups as a data source to measure developments in alternative proteins because of their agility and innovation.
Unlike traditional reviews that focus on production methods or specific protein sources, this approach addresses alternatives to animal/fish-based proteins through three strategies: replacing existing products with available substitutes, modifying existing non-animal proteins, and creating new proteins using technologies such as three-dimensional (3D) bioprinting and precision fermentation.
Market penetration of these alternatives depends on scalability and cost. To demonstrate this, the startups were selected based on their protein offerings, technology approaches, and active status and categorized into the pillars of Substitute, Modify, and Create.
These startups were analyzed in terms of their scientific basis, stages of product development and key challenges, providing a comprehensive view of the alternative protein ecosystem.
A problem-solving strategic innovation approach was used to design the start-up ecosystem. The problem to be solved is to find an alternative to animal/fish based proteins and when it comes to finding an alternative there are three main options to consider: (1) the use of a substitute, (2 ) the modification of existing non-animal/non-animal fish protein sources and (3) creation of an alternative protein source. (1) Substitution: this option involves using a readily available substitute for the target compound, e.g. current vegetarian diet options. (2) Modification: this option considers the modification of existing non-animal/non-fish protein sources to substitute for the target compound, e.g. insect-based protein. (3) Brand: This option comes from the point of view of product innovation, providing the most potential while also addressing the greatest challenges. It includes the use of new technological processes for the production of proteins, e.g. 3D bioprinting, cell culture products, precision fermentation, etc.
Meat protein replacement
The “Replacement” strategy involves using existing non-animal ingredients that can replace animal and fish proteins. While this approach may not seem particularly innovative, it leverages modern advances in machine learning and digital databases.
Machine learning algorithms can design plant-based food substitutes by analyzing extensive data on food composition, nutrition and recipes. For example, some startups have developed tools that leverage artificial intelligence (AI) to convert any recipe into a plant-based version simply by entering it into a search box on the website.
Assuming the same consumer perception of different alternative protein products, their market penetration will depend mainly on their scale (ability to move from niche to mass market without compromising quality) and cost (at least parity with protein products based on animals/fish). These two parameters were used to map the market penetration potential of different protein alternatives using current market examples. Note: Product examples are for illustrative purposes only and are not to scale.
Use of non-animal protein sources
The “Modification” strategy uses existing non-animal protein sources such as plants and insects.
Insects, consumed by approximately two billion people worldwide, are a sustainable source of protein because they require fewer resources and have less environmental impact. Insect-based foods are gaining ground in Western markets and the market for edible insects is predicted to grow significantly.
Some companies are expanding through strategic partnerships and innovations such as vertical farming and Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) technology. Government support also helps scale this industry. Despite the benefits, challenges remain in terms of consumer acceptance and ensuring food safety.
Humans have long consumed plant-based proteins, and modern processing technologies have enhanced their appeal as alternatives to meat and dairy. The market for plant-based meat analogs (PBMA) and dairy alternatives (PBDA) is expanding, driven by startups and large food companies.
Innovations such as 3D bioprinting and texture enhancement techniques are addressing the sensory and structural challenges of plant-based foods. Despite advances, challenges include concerns about allergens, improvements in taste, and the need for comprehensive safety data.
Growing lab-grown meat
The “Make” strategy focuses on the production of lab-grown meat, which involves growing animal cells in bioreactors. This method has advanced significantly, with several companies developing meat culture products such as chicken or beef.
However, lab-grown meat faces hurdles such as regulatory approval, high production costs, and sensory acceptance. Innovations in 3D bioprinting and precision fermentation aim to overcome these challenges.
These technologies promise to reduce environmental impact and improve sustainability, but require significant investment and infrastructure development.
conclusions
New technologies promote alternative protein sources to address food safety and environmental challenges by reducing emissions and land use. The alternative protein ecosystem is evolving through innovative approaches to replace, modify and produce protein sources.
Each strategy has unique benefits and challenges, from leveraging artificial intelligence for plant substitutions to cutting-edge lab-grown meat technologies. The success of these alternatives will depend on overcoming technical, regulatory and consumer acceptance barriers.
Alternative proteins, including insect, fungal, plant and cell (cultured meat and fish) proteins, have seen significant growth, with products now available in shops and restaurants.
However, challenges remain in terms of consumer acceptance, affordability and market accessibility due to high production costs, scalability issues and regulatory hurdles.
Addressing these challenges involves interdisciplinary research, new partnerships, global alliances and continued investment. Governmental and non-governmental organizations form partnerships to support innovation and regulatory work, fostering startup growth and breakthrough innovations.
