Abstract
Abstract A process for preserving the bright red color of fresh raw uncured red meat by incorporating into the meat a special gammapyrone and storing the meat at a refrigerated temperature for a period of at least twenty-four hours, the special gamma-pyrone being 3-hydroxy-2-methyl-gamma-pyrone or 3-hydroxy-2-ethyl-gammapyrone or 5-hydroxy-2-methyl-gamma-pyrone or mixtures thereof. Also meats having a bright red color and containing said special gamma-pyrone for inhibiting change in color.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
67 words
IN A METHOD FOR PRODUCING TUBULAR WAFFLE SHAPER BY WINDPRESERVE THE RED COLOR OF SAID MEAT DURING A STORAGE PERIOD OF 24 HOURS OR MORE, THE STEP OF INTRODUCING INTO SAID MEAT FROM 0.01 TO 0.50 PERCENT BY WEIGHT OF A GAMMA-PYRONE SELECTED FROM THE CLASS CONSISTING OF 3-HYDROXY-2-METHYL-GAMMAPYRONE, 3-HYDROXY-2-ETHYL-GAMMA-PYRONE, 5-HYDROXY-2METHYL-GAMMA-PYRONE AND MIXTURES THEREOF, WHEREBY SAID GAMMA-PYRONE ACTS TO SUBSTANTIALLY PRESERVED SAID RED COLOR DURING SAID PERIOD.
Claim 2
Dependent Claim
67 words
IN A METHOD FOR PRODUCING TUBULAR WAFFLE SHAPER BY WINDPRESERVE THE RED COLOR OF SAID MEAT DURING A STORAGE PERIOD OF 24 HOURS OR MORE, THE STEP OF INTRODUCING INTO SAID MEAT FROM 0.01 TO 0.50 PERCENT BY WEIGHT OF A GAMMA-PYRONE SELECTED FROM THE CLASS CONSISTING OF 3-HYDROXY-2-METHYL-GAMMAPYRONE, 3-HYDROXY-2-ETHYL-GAMMA-PYRONE, 5-HYDROXY-2METHYL-GAMMA-PYRONE AND MIXTURES THEREOF, WHEREBY SAID GAMMA-PYRONE ACTS TO SUBSTANTIALLY PRESERVED SAID RED COLOR DURING SAID PERIOD.
Claim 3
Dependent Claim
87 words
In a process for treating fresh raw uncured red meat to preserve the red color thereof, the steps of introducing into said meat from 0.01 to 0.50 percent by weight of a gamma-pyrone compound selected from a class consisting of 3-hydroxy-2-methyl-gamma-pyrone, 3-hydroxy-2-ethyl-gamma pyrone, 5-hydroxy-2-methyl-gamma-pyrone and mixtures thereof, and storing said meat into which said gamma-pyrone has been introduced at a temperature of from 30* to 60*F. for a period of at least 24 hours, whereby said gamma-pyrone acts to substantially preserve said red color during said period.
Claim 4
Dependent Claim
87 words
In a process for treating fresh raw uncured red meat to preserve the red color thereof, the steps of introducing into said meat from 0.01 to 0.50 percent by weight of a gamma-pyrone compound selected from a class consisting of 3-hydroxy-2-methyl-gamma-pyrone, 3-hydroxy-2-ethyl-gamma pyrone, 5-hydroxy-2-methyl-gamma-pyrone and mixtures thereof, and storing said meat into which said gamma-pyrone has been introduced at a temperature of from 30* to 60*F. for a period of at least 24 hours, whereby said gamma-pyrone acts to substantially preserve said red color during said period.
