Abstrakt: Background: The most common milk-clotting enzymes in the cheese industry are recombinant chymosins. Food naturalness is a factor underpinning consumers' food choice. For consumers who avoid food with ingredients from genetically modified organisms (GMOs), the use of vegetable-based rennet substitute in the cheese formulation may be a suitable solution. Artichokes that deviate from optimal products, when allowed to bloom due to flower protease composition, are excellent as raw material for vegetable rennet preparation. As enzymatic milk clotting exerts a significant impact on the characteristics of the final product, this product should be studied carefully.
Results: Mature flowers from unharvested artichokes (Cynara scolymus cv. Francés) that did not meet aesthetic standards for commercialization were collected and used to prepare a flower extract. This extract, as a coagulant preparation, enabled the manufacture of cheeses with distinctive characteristics compared with cheeses prepared with chymosin. Rennet substitution did not affect the actual yield but led to significant changes in dry matter yield, humidity, water activity, protein content, and color, and conferred antioxidant activity to the cheeses. The rennet substitution promoted significant modifications in springiness, and in the microstructure of the cheese, with a more porous protein matrix and an increment in the size of the fat globules. Both formulations showed a similar microbiota evolution pattern with excellent microbiological quality and good sensory acceptance.
Conclusions: The rennet substitute studied here produced a cheese adapted to specific market segments that demand more natural and healthier products made with a commitment to the environment but well accepted by a general cheese consumer. © 2020 Society of Chemical Industry.
