Abstract
A matrix for incorporating titanium dioxide into extruded plant protein extenders for natural meat products is disclosed. In particular, this matrix made from vegetable protein is useful for incorporating TiO.sub.2 tracer in extruded plant protein extenders in such a way that there will be reduced optical contrast with natural ground meat fibers.
Claims6
A process for preparing natural meat products containing extruded vegetable protein extender with titanium dioxide tracer comprising:
- a. blending isolated vegetable protein capable of being rendered insoluble and titanium dioxide.
- b. hydrating said blend,
- c. reacting said hydrated blend under elevated temperature until said protein is substantially insolubilized thereby forming a matrix;
- d. adding said matrix as fine particles in dried form to a vegetable protein to form a mixture,
- e. hydrating said mixture,
- f. extruding said hydrated mixture to form a vegetable protein extender,
- g. combining said extender with a natural meat product whereby the pigmentation of the titanium dioxide does not detract from the appearance of the combined product.
