Abstract
Abstract Food products containing high levels of meat or textured vegetable protein meat analog are sterilized without development of off-flavors in the meat or meat analog by a process including: (1) adjusting the pH to below about 4.6; (2) maintaining organic acid levels between about 0.4% and about 0.75% (expressed as anhydrous citric acid); (3) high temperature, short time processing of the food products; and (4) hot-fill-and-hold packing of the product in containers.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
119 words
A process for preventing spoilage while maintaining flavor quality in a low-acid food product containing textured vegetable protein, comprising the steps of: (a) acidifying the food product to a pH of from about 4.2 to about 4.6 and an organic acid level of about 0.4% to about 0.75%; (b) high temperature short-time sterilizing the food product to a F 0 of at least about 0.3; (c) then packing the product at a temperature of from about 85° C. (185° F.) to 100° C. (212° F.); (d) then hermetically sealing the product; and (e) then holding the packed, sealed product at a temperature of at least about 85° C. (185° F.) for a time of at least about 3 minutes.
