Decompartmentalisation as a simple color manipulation of plant-based marbling meat alternatives

Recent efforts for cell-based meat cuts focus on engineering edible scaffolds, with visual cues which are key to enhancing consumer acceptance, receiving less attention Here, we employed artificial intelligence (AI)-based screening of potential plant materials and discovered that jackfruit (Artocarpus heterophyllus) has the natural structures to recapitulate marbling visuals of meat cuts. Plant tissue compositions are exploited for its differential polyphenol adsorption to produce complex marbling patterns. A one-step colour control method by varying oxidation and incubation conditions of polyphenols was developed to produce permanent meat-like colours resembling chicken, pork, and beef. The scaffold exhibits a meat-like browning behaviour when cooked and is shown to support high-density porcine myoblasts culture without masking the marbled appearance. Surveys with 78 volunteers found that marbled jackfruit scaffolds improved consumer perception of cell-based meat by similar to 8%. Our approach of combining AI, tissue engineering, and sensory science unlocks the possibility of creating a range of novel cell-based meat cuts with consumer focus.

Automated summary

Researchers used artificial intelligence to screen potential plant materials and found that jackfruit has natural structures to mimic marbling visuals of meat cuts. They developed a method to produce permanent meat-like colours by controlling the oxidation and incubation conditions of polyphenols. This approach of combining AI, tissue engineering, and sensory science unlocks the possibility of creating novel cell-based meat cuts with consumer focus.
