Unlike cultivated meat, which requires extensive downstream processing like scaffolding and formulation, plant cell products like cocoa are nearly finished post-bioreactor. The process is simply de-watering, drying, and milling, which significantly lowers costs and simplifies consumer understanding of the final product.

Unlike plant-based systems that suffer from low protein expression and high scaling costs, silkworm pupae function as dense, natural bioreactors. This allows for high-yield production at a low cost, making oral vaccines commercially viable where previous attempts have failed.
California Cultured is commercializing a premium, high-flavanol cocoa powder first. This niche, high-margin product generates revenue and funds the R&D required to lower COGS for future, lower-priced commodity products like conventional cocoa and coffee, mirroring Tesla's Roadster-to-Model 3 strategy.
The silkworm platform changes the manufacturing paradigm from "scaling up" to "scaling out." Instead of building larger, more expensive bioreactors, production is increased simply by using more pupae. This model offers greater flexibility to adapt to demand, lowers infrastructure costs, and reduces the engineering risks associated with traditional scale-up.
To make commodity products like cocoa economically viable, California Cultured rejects expensive stainless-steel bioreactors (costing up to $1M). Instead, they use simple plastic tanks costing only a few thousand dollars. This drastically reduces CapEx and is a fundamental shift in biomanufacturing philosophy for low-margin goods.
Consumers are trained by food packaging to look for simple, bold 'macros' (e.g., '7g Protein,' 'Gluten-Free'). Applying this concept to non-food items by clearly stating key attributes ('Chemical-Free,' 'Plant-Based') on the packaging can rapidly educate consumers at the point of purchase and differentiate the product.
The use of low-cost, scalable plastic tank bioreactors eliminates the need for traditional, expensive GMP facilities. This allows companies to convert cheap, underutilized office space into production labs, enabling a novel business model of decentralized, onshore manufacturing that dramatically lowers real estate and operational costs.
Silkworm biomanufacturing offers incredible production density, with one pupa producing 10-20 mg of protein. Scaling requires simply adding more pupae ('scaling out') rather than building larger facilities ('scaling up'), enabling decentralized, small-footprint manufacturing.
Existing agricultural giants have no incentive to process small batches of novel crops for startups. To prove market demand and achieve scale, innovators must acquire their own processing capacity, a risky but essential move to get products to market.
According to a published comparative study, a single silkworm pupa can produce the equivalent amount of recombinant protein as approximately 120 mL of SF9 insect cell culture. This high-density output creates massive economic and footprint advantages by eliminating the need for large bioreactors, sterilized media, and extensive cleaning validation.
The term "cellular agriculture" has become synonymous with "cultivated meat," attracting political resistance and consumer skepticism. The industry must actively broaden the definition to include plant cell products (like cocoa) and precision fermentation to improve public perception and accelerate adoption.
