Vegetable rennin segmentation by type categorises the product into microbial‑derived, plant‑extracted, and enzyme‑modified variants, each reflecting a distinct production route and performance profile. Microbial‑derived rennin, produced through recombinant fungi or bacteria, dominates the market (≈60 %) because it offers consistent activity, scalable fermentation, and lower cost of goods; it underpins most commercial food‑processing contracts. Plant‑extracted rennin, obtained from sources such as cardoon or fig latex, represents about 25 % of sales; its niche appeal lies in clean‑label positioning and consumer preference for minimally processed ingredients, especially in premium cheese and specialty dairy‑free products. Enzyme‑modified rennin, generated by post‑fermentation chemical or enzymatic tailoring, accounts for the remaining 15 %; it is favoured in pharmaceutical and high‑precision R&D contexts where specific proteolytic profiles are required. The relative weight of each type directly influences the overall vegetable rennin market size, as production capacity, pricing elasticity, and regulatory compliance differ across these sub‑categories, shaping the market taxonomy.
