A Lab-Grown Salmon Taste Test And More Foodie Innovations

October 24, 2025

Key Takeaways Copied to clipboard!

  • The cultivated salmon from Wild Type, currently served in four US restaurants, has a texture similar to traditional salmon but a milder flavor, though its bright orange color initially resembled a clownfish. 
  • The cultivated meat industry prefers terms like "cultivated" or "cell-cultured" over "lab-grown" to mitigate public aversion stemming from the biomedical feel of the technology, which remains a significant hurdle for mainstream adoption. 
  • Innovation in food technology, including both cell-cultured meat (which requires significant scaling investment) and locally grown heirloom crops like mung beans, is viewed by experts as a necessary diversification of solutions for a sustainable food future, not a replacement for traditional agriculture.

  • Key Takeaway: Cultivated salmon from Wild Type, served Nigiri style, possessed a blindingly bright orange color, prompting an initial comparison to Nemo.
  • Summary: Producer Kathleen Davis sampled cultivated salmon from Wild Type at Robin restaurant in San Francisco. The fish was served Nigiri style and was noted for its bright orange color, which the chef suggested was closer to wild salmon. Davis found the texture spot-on for sushi fish, though the flavor was mild and less pronounced than the traditional salmon served alongside it.
Comparing Cultivated Texture

  • Key Takeaway: Chef Adam Tortosa noted that cultivated salmon breaks more rigidly when sliced or eaten compared to traditional salmon.
  • Summary: Chef Adam Tortosa, who has extensive experience handling salmon, observed that the way the cultivated salmon breaks is different from real salmon, describing it as more rigid. He also noted that the cultivated fish did not react well to torching, unlike traditional salmon. Another chef, Renee Erickson, compared the texture of the cultivated fish to tofu rather than muscle tissue.
Public Perception and Terminology

(00:08:09)
  • Key Takeaway: The term “lab-grown meat” is actively avoided by the industry because it feels too biomedical, favoring “cultivated” or “cell-cultured” to improve public acceptance.
  • Summary: Aversion to cultivated meat often stems from its perceived biomedical nature. Chefs noted that interest in trying it at restaurants is mixed, with 10 to 20% of patrons refusing it outright. Industry professionals prefer terms like cultivated or cell-cultured to move away from clinical branding, though even ‘cell cultured’ can feel clinical to some.
Scalability and Industry Hurdles

(00:10:00)
  • Key Takeaway: Wild Type currently produces less than 10 tons of meat annually, and scaling up requires significant investment, especially as biotech funding has recently shifted toward AI.
  • Summary: Current production capacity for Wild Type is extremely low compared to global salmon consumption, taking two to three weeks to produce one sushi-ready filet. The product is priced competitively with premium Pacific salmon. Scaling the industry depends heavily on increased financial investment to drive innovation and improve production efficiency.
Goal of Cultivated Meat

(00:11:17)
  • Key Takeaway: The goal of the cultivated meat industry is to offer an additional option to consumers, not to replace traditional agriculture or aquaculture entirely.
  • Summary: Industry participants agree that cultivated meat will not replace traditional farming methods due to persistent demand for conventional products. The aim is to provide another choice for consumers globally, with ecosystems developing in Asia, Europe, and Australia in addition to the US. Many proponents are passionate about using this technology to alleviate pressure on the seafood industry and promote sustainability.
Engineering Scaffolds for Meat

  • Key Takeaway: Dr. Rachael Floreani’s lab engineers colorless, tasteless scaffolds, often made from upcycled whey protein, that mimic the look and feel of steak to guide cell growth.
  • Summary: Dr. Floreani transitioned from designing orthopedic implants to creating materials that serve as a home for cells to develop into recognizable meat structures. These scaffolds, which look like sponges, dictate tissue development; making them hard encourages bone-like structure, while squishy scaffolds encourage fat development. The cells are grown in a nutrient-rich soup, often with oxygenation provided by a bubbler.
Mung Beans in Local Food Systems

(00:18:31)
  • Key Takeaway: Alexis Yamashita is working to establish a local supply chain for mung beans in Vermont, focusing on open-pollinated, heirloom varieties that meet community taste preferences.
  • Summary: Mung beans are culturally relevant to many communities in Vermont, but most supply is imported internationally. Yamashita has trialed over 50 varieties locally, finding many adapt well to Vermont’s environment. These open-pollinated, heirloom varieties allow farmers to save their own seed, strengthening local food access and adaptation to climate change.
Protein Density and Collaboration

(00:20:37)
  • Key Takeaway: Mung beans are a key plant-based protein source, already used in commercial products like Beyond Burgers, and the cultivated meat and plant-based sectors collaborate rather than compete to feed more people.
  • Summary: Mung beans are a significant plant-based protein, and their nutrient density is driving interest in alternative protein products. Experts at food innovation conferences emphasize collaboration between different food tech sectors to honor existing food preferences while diversifying protein sources. It is difficult to convert people’s diets, so the focus is on honoring preferences through new options.
Nutrients and Future Access

(00:27:47)
  • Key Takeaway: Cultivated meat can be engineered to be more nutrient-dense than traditional meat, potentially offering higher concentrations of specific nutrients like in hypothetical nutrient-dense meatballs.
  • Summary: While the amino acid profile of cultivated meat mirrors traditional meat, components derived from vasculature in red meat may be difficult to mimic. The technology allows for nutritional enhancement, such as creating meatballs four times as nutrient-dense as conventional ones. For local food systems, embracing technology like food tech in Vermont can retain talent and provide affordable, accessible food options for communities.
