Abstract: The present disclosure generally relates, in certain aspects, to cultivated meat and other cultivated animal-derived products. In some embodiments, muscle and/or fat cells can be grown on microcarriers or other scaffolds, for example, in a bioreactor or other in vitro cell culture system. The microcarriers or other scaffolds can comprise materials such as fibrin. The fibrin may be formed into hydrogels or other articles, which may be edible in some cases. The microcarriers may also contain grooves or other structures in some instances. In certain embodiments, the microcarriers may be present within the final product, e.g., in a cultivated meat product. Other embodiments are generally directed to methods of making or using microcarriers or cultivated meat products, kits involving these, or the like.

Abstract: The present disclosure generally relates, in certain aspects, to cultivated meat and other cultivated animal-derived products. In some embodiments, such products may include fat replicas, which may improve taste, appearance, etc. In some cases, a fat replica can be formed by forming an emulsion of fat and a non-human blood plasma, then causing the blood plasma to crosslink and/or clot, e.g., forming a hydrogel containing the fat emulsion. In some cases, the fat replica may be used to make a cultivated meat product, e.g., by combining with muscle replicas, lysate of non-human red blood cells, etc. Other embodiments are generally directed to methods of making or using such fat replicas, the microcarriers, or the cultivated meat products, kits involving these, or the like.

Abstract: The present disclosure generally relates, in certain aspects, to cultivated meat and other cultivated animal-derived products. In some embodiments, the whole blood of a non-human animal is separated into various components (e.g., concentrated red blood cells, blood plasma, etc.). Some embodiments are generally directed toward incorporating coloring or “redness” into a product. For example, colorants may be added to a cultivated meat product to improve its color. The colorant may comprise a lysate of non-human red blood cells, e.g., containing hemoglobin. In some embodiments, the lysate may be obtained from blood withdrawn from living animal donors. Other embodiments yet are generally directed toward the composition and method of use of the lysate, cultivated meat products, kits involving these, or the like.
