Alpine Bio’s 10th Patent Ushers New Age in Plant Proteins

Molecular Farming Breakthrough

In what is being hailed as a significant advancement in the field of molecular farming, Nobell Foods, now rebranded as Alpine Bio, has secured its 10th US patent, marking a new era in the quest to produce animal proteins more sustainably. The San Francisco-based startup, founded by Magi Richani in 2016, has expanded its vision from creating animal-free casein for cheese products to working on up to 15 proteins that can be expressed in various plants.

The Science of Plant-Based Proteins

Alpine Bio’s technology is at the forefront of a revolutionary approach to food production. At its core, the startup is genetically engineering soybeans to produce casein proteins by inserting bovine DNA sequences into the plant genome. This is a significant challenge, as plants naturally contain proteases that break down casein. To overcome this, Alpine Bio has developed techniques to shield the casein from these enzymes, allowing for increased accumulation of the protein within the plant. This is critical because casein is responsible for the melt and stretch qualities of cheese, which have been difficult to replicate in plant-based alternatives.

The company’s approach differs from precision fermentation, which utilizes microbes to produce individual casein proteins. Richani points out that plants can be engineered to produce two or more casein proteins simultaneously, potentially leading to a more cost-effective and scalable solution. With the ability to produce all four types of casein proteins, Alpine Bio’s method could revolutionize the way we think about protein production.

A Broadening IP Portfolio

Alpine Bio’s latest patent encompasses not only the production of these proteins but also their use in food formulations. This broad claim strengthens the company’s intellectual property portfolio, positioning it as a significant player in the industry. The robustness of their IP means that any entity looking to produce these proteins in plants will likely need to engage with Alpine Bio’s technology.

Why Soybeans?

The choice of soybeans as the production vehicle for casein is strategic. Soy is a high-protein commodity crop, and the existing infrastructure for soybean processing can be readily adapted for Alpine Bio’s needs. The company’s approach targets the balance between achieving the necessary purity of casein while maintaining cost-effectiveness. While complete purification is possible, it would lead to higher costs. Instead, Alpine Bio aims to produce highly functional cheeses with a blend of casein and soy protein, which would not limit market potential due to the common presence of both dairy and soy in various food products.

Allergen Management and Regulatory Compliance

Alpine Bio is acutely aware of the importance of allergen management in its supply chain, particularly in light of recent FDA warnings to companies in the molecular farming space. The company is taking proactive steps to ensure that allergens are controlled and that the integrity of the supply chain remains intact.

Funding the Future of Food

Despite changing market conditions, Alpine Bio has witnessed a surge in interest from investors who recognize the potential of molecular farming to achieve price parity with traditional dairy. This shift in investor sentiment is a testament to the growing acknowledgment of the viability and necessity of alternative protein sources.

Looking Ahead

With USDA permits in hand and plants in the ground, Alpine Bio is fine-tuning its purification processes. Internal tastings of Nobell Foods cheese are underway, with public tastings slated for the following year. The majority of the required processing infrastructure is already in place, with minimal additional modifications needed.

Alpine Bio’s journey from a startup focused on cheese to a broader molecular farming enterprise is emblematic of the dynamic nature of agritech innovation. As the company navigates the self-GRAS process and engages with the FDA, the food industry watches closely. The implications of Alpine Bio’s work are vast, promising a future where plant-derived casein and other proteins could become commonplace, reshaping our understanding of sustainable food production and consumption.
