Abstract
Abstract Process for increasing the shelf life of precooked dehydrated protein and oil containing ingredients for foods by heating an emulsion-suspension of said peanuts to high temperatures and dehydrating the cooked emulsion-suspension, also adjusting the texture of said dehydrated material by processing treatments prior to cooking and dehydration, and the oil-protein ratio by removing part or all of the oil from the peanuts by mechanical means or by extraction, respectively, or by mixing ground peanuts in predetermined amounts with materials poor in fat and rich in proteins. The invention also relates to the precooked dehydrated ingredients so made and the food products containing the same. This is a continuation-in-part of application Ser. No. 187,837, filed Oct. 8, 1971 now U.S. Pat. No. 3,800,056 which is a CIP of Ser. No. 839,673, filed 7/7/69 now Pat. No. 3,689,287.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
147 words
A process for making precooked dehydrated peanut food ingredients which comprises coarsely grinding shelled peanuts without releasing oil, and without reducing the moisture content of the peanuts, adding a sufficient amount of water to the coarsely ground peanuts to form a slurry and prevent congealment to a semisolid when the slurry is disintegrated, disintegrating the slurry in such a manner that the cellular tissue is torn into shreads thereby releasing oil, water soluble protein and carbohydrates to form an emulsion of oil with the water, and a suspension of solids, heating the emulsion-suspension at a temperature of about 200° F for 30 minutes up to about 325° F for about 5 seconds to increase the consistency as the protein coagulates and starch is gelatinized, and to stabilize the oil against oxidation, and drying the resultant material thereby providing a slightly coarse texture in the dehydrated food ingredient.
Claim 2
Dependent Claim
147 words
A process for making precooked dehydrated peanut food ingredients which comprises coarsely grinding shelled peanuts without releasing oil, and without reducing the moisture content of the peanuts, adding a sufficient amount of water to the coarsely ground peanuts to form a slurry and prevent congealment to a semisolid when the slurry is disintegrated, disintegrating the slurry in such a manner that the cellular tissue is torn into shreads thereby releasing oil, water soluble protein and carbohydrates to form an emulsion of oil with the water, and a suspension of solids, heating the emulsion-suspension at a temperature of about 200° F for 30 minutes up to about 325° F for about 5 seconds to increase the consistency as the protein coagulates and starch is gelatinized, and to stabilize the oil against oxidation, and drying the resultant material thereby providing a slightly coarse texture in the dehydrated food ingredient.
Claim 3
Dependent Claim
18 words
The process according to claim 1 in which the peanuts are steamed to inactivate lipoxygenase prior to grinding.
Claim 4
Dependent Claim
53 words
The process according to claim 1 wherein before the step of grinding, the protein to oil ratio of precooked dehydrated food ingredients made from peanuts is adjusted and the shelf life of said dehydrated food ingredients is increased, comprising the step of removing part of the oil content of peanuts by mechanical means.
Claim 5
Dependent Claim
24 words
The process according to claim 1 wherein before the step heating essentially all of the oil of the peanuts is removed by solvent extraction.
Claim 6
Dependent Claim
58 words
Peanut ingredient made in accordance with the process of claim 1 used as extender to natural food products, consisting of precooked dehydrated peanut flakes, granules, flour, or other physical forms and at least one additive in a amount ranging from 0.01 to 0.02 weight percent of the peanut ingredients for extending the shelf life of said peanut ingredient.
Claim 7
Dependent Claim
51 words
Food products containing a substantial amount of precooked, dehydrated peanut derived flakes, granules, flour, made in accordance with the process of claim 8 having various levels of protein and oil contents ranging from about 27 to 60% by weight of protein and from about 0 to 50% by weight of oil.
Claim 8
Dependent Claim
13 words
The process of claim 1 whereby said step of dehydration comprises spray drying.
Claim 9
Dependent Claim
13 words
The process of claim 1 whereby said step of dehydration comprises drum drying.
Claim 10
Dependent Claim
43 words
The method according to claim 1 wherein prior to the step of drying, the method comprising adding at least one or more of the following proteins carbohydrates, cereal flours, legume flours, non-fat milk solids, amino acids, vitamin, and minerals to the peanut-water mixture.
