Abstract
Abstract A synergistic antioxidant composition comprising a phenolic-type antioxidant and a degraded protein, and a method of stabilizing food products against oxidation therewith. BHA, BHT, and Alpha tocopherol are particularly suitable phenolic-type antioxidants for use in such compositions. Autolyzed yeast or hydrolyzed vegetable protein are particularly effective degraded proteins for such use in compositions for protecting food products, permitting marked reductions in the concentrations of the phenolic-type antioxidants.

Claim 1
Independent Claim
81 words
A PROCESS FOR THE STABILIZATION AGAINST OXIDATION OF OXIDATION SUSCEPTIBLE FOODS, WHICH COMPRISES ADDING THERETO AN ANTIOXIDATIVE AMOUNT OF AN ANTIOXIDANT COMPOSITION COMPRISING (A) A COMPOUND SELECTED FROM THE GROUP CONSISTING OF BUTYLATED HYDROXYANISOLE, BUTYLATED HYDROXYLOTUENE, AND A-TOCOPHEROL, AND (B) AUTOLYZED YEAST PROTEIN SAID AUTOLYZED YEAST PROTEIN BEING PRESENT IN SAID ANTIOXIDANT COMPOSITION IN AN AMOUNT WHICH IS EFFECTIVE AS A SYNERGIST FOR THE ANTIOXIDANT ACTION OF SAID COMPOUND SELECTED FROM THE GROUP CONSISTING OF BUTYLATED HYDROXYANISOLE, BUTYLATED HYDROXYTOLUENE, AND A-TOCOPHEROL.

Claim 3
Dependent Claim
68 words
The process of claim 1, wherein said compound selected from the group consisting of butylated hydroxyanisole, butylated hydroxytoluene, and Alpha -tocopherol is added to said oxidation susceptible food in a concentration of from about 0.0005 percent to about 0.05 percent by weight and said autolyzed yeast protein is added to said oxidation susceptible food in a concentration of from about 0.5 percent to about 50 percent by weight.
