Claim 1
Independent Claim
138 words
AN EMULSIFIED OIL DRESSING HAVING A PH IN THE RAGE OF FROM ABOUT 3 TO ABOUT 4.5 COMPRISING WATER, OIL, FLAVOURING MATERIALS AND AN EMULSIFYING AGENT, SAID EMULSIFYING AGENT, CONSISTING ESSENTIALLY OF SERUM PROTEIN OBTAINED FROM MILK, SAID OIL BEING PRESENT AT A LEVEL OF FROM ABOUT 50 TO ABOUT 80 PERCENT BY WEIGHT, SAID SERUM PROTEIN BEING AT LEAST ABOUT 70 PERCENT BY WEIGHT DENATURED PROTEIN WHEN SAID OIL IS PRESENT AT A LEVEL OF FROM ABOUT 50 TO ABOUT 70 PERCENT BY WEIGHT AND SAID SERUM BEING LESS THAN ABOUT 20 PERCENT BY WEIGHT DENATURED PROTEIN WHEN SAID OIL IS PRESENT AT A LEVEL OF FROM ABOUT 70 TO ABOUT 80 PERCENT BY WEIGHT, SAID SERUM PROTEIN BEING PRESENT AT A LEVEL OF FROM ABOUT 0.5 PERCENT TO ABOUT 5.0 PERCENT BY WEIGHT OF SAID DRESSING.
Claim 2
Dependent Claim

AN EMULSIFIED OIL DRESSING HAVING A PH IN THE RAGE OF FROM ABOUT 3 TO ABOUT 4.5 COMPRISING WATER, OIL, FLAVOURING MATERIALS AND AN EMULSIFYING AGENT, SAID EMULSIFYING AGENT, CONSISTING ESSENTIALLY OF SERUM PROTEIN OBTAINED FROM MILK, SAID OIL BEING PRESENT AT A LEVEL OF FROM ABOUT 50 TO ABOUT 80 PERCENT BY WEIGHT, SAID SERUM PROTEIN BEING AT LEAST ABOUT 70 PERCENT BY WEIGHT DENATURED PROTEIN WHEN SAID OIL IS PRESENT AT A LEVEL OF FROM ABOUT 50 TO ABOUT 70 PERCENT BY WEIGHT AND SAID SERUM BEING LESS THAN ABOUT 20 PERCENT BY WEIGHT DENATURED PROTEIN WHEN SAID OIL IS PRESENT AT A LEVEL OF FROM ABOUT 70 TO ABOUT 80 PERCENT BY WEIGHT, SAID SERUM PROTEIN BEING PRESENT AT A LEVEL OF FROM ABOUT 0.5 PERCENT TO ABOUT 5.0 PERCENT BY WEIGHT OF SAID DRESSING.
Claim 3
Dependent Claim
17 words
An emulsified oil dressing in accordance with claim 1 wherein said serum protein is derived from whey.
Claim 4
Dependent Claim
60 words
An emulsified oil dressing in accordance with claim 2 wherein said whey is treated to provide a whey product having from about 25 to about 80 percent by weight protein, from about 15 to about 65 percent lactose and less than about 50 percent by weight ash, the level of said ash being based on the level of said protein.
Claim 5
Dependent Claim
47 words
An emulsified oil dressing in accordance with claim 1 wherein said oil is present at a level of from about 50 to about 70 percent by weight and wherein said serum protein is present at a level of from about 3 to about 5 percent by weight.

Dependent Claim
47 words
An emulsified oil dressing in accordance with claim 1 wherein said oil is present at a level of from about 70 to about 80 percent by weight and wherein said serum protein is present at a level of from about 0.5 to about 1.5 percent by weight.
Claim 7
Independent Claim
236 words
A method for making an emulsified oil dressing having a pH in the range of from about 3 to about 4.5 comprising the steps of treating whey to provide a whey product having from about 25 to about 80 percent by weight protein, from about 15 to about 65 percent by weight lactose and less than about 50 percent by weight ash, the level of said ash being based on the level of said protein dispersing said whey product in water to provide an aqueous whey dispersion, blending said aqueous whey dispersion with an oil and sufficient edible acid to provide a loose emulsion having a pH in the range of from about 3 to about 4.5 and homogenizing said loose emulsion to provide an emulsified oil dressing having the appearance of a mayonnaise-type dressing, said oil being present at a level of from about 50 to about 80 percent by weight, said serum protein being at least about 70 percent by weight denatured protein when said oil is present at a level of from about 50 to about 70 percent by weight and said serum protein being less than about 20 percent by weight denatured protein when said oil is present at a level of from about 70 to about 80 percent by weight, said serum protein being present at a level of from about 0.5 to about 5.0 percent by weight of said dressing.
Claim 8
Independent Claim
236 words
A method for making an emulsified oil dressing having a pH in the range of from about 3 to about 4.5 comprising the steps of treating whey to provide a whey product having from about 25 to about 80 percent by weight protein, from about 15 to about 65 percent by weight lactose and less than about 50 percent by weight ash, the level of said ash being based on the level of said protein dispersing said whey product in water to provide an aqueous whey dispersion, blending said aqueous whey dispersion with an oil and sufficient edible acid to provide a loose emulsion having a pH in the range of from about 3 to about 4.5 and homogenizing said loose emulsion to provide an emulsified oil dressing having the appearance of a mayonnaise-type dressing, said oil being present at a level of from about 50 to about 80 percent by weight, said serum protein being at least about 70 percent by weight denatured protein when said oil is present at a level of from about 50 to about 70 percent by weight and said serum protein being less than about 20 percent by weight denatured protein when said oil is present at a level of from about 70 to about 80 percent by weight, said serum protein being present at a level of from about 0.5 to about 5.0 percent by weight of said dressing.
Claim 9
Dependent Claim
49 words
A method in accordance with claim 6 wherein said oil is present at a level of from about 50 to about 70 percent by weight and wherein said whey product is present at a level sufficient to provide from about 3 to about 5 percent by weight serum protein.
Claim 10
Dependent Claim
47 words
A method in accordance with claim 6 wherein said oil is present at a level from about 70 to about 80 percent by weight and wherein said whey is present at a level sufficient to provide from about 0.5 to about 1.5 percent by weight serum protein.
