Abstract
Abstract The addition of a small amount of a lecithin-in-water suspension to the formulation of dough-based fried snack foods improves dough transfer, sheeting and cutting, and significantly reduces clumping during frying, without the rapid buildup of free fatty acids, and without significant darkening of frying oil normally associated with the frying of foods containing lecithin.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
138 words
In a process for the preparation of a comestible product which includes the steps of: (a) preparing a dough of pregelatinized starch, a dry flaked or powdered cereal or flakes of a starchy vegetable, vegetable oil, water, sugar and salt; (b) sheeting the dough; (c) cutting the sheeted dough to produce a shaped chip; (d) frying the shaped chip in fat or oil; and (e) seasoning the fried product, the improvements in the process comprising; forming a suspension of lecithin in water, the amount of lecithin being at least 0.02% of the weight of the pregelatinized starch and dry flaked or powdered cereal or flakes of starchy vegetable, and less than an amount in which the sheeted dough becomes lacy and breakage occurs, and adding the lecithin suspension to the dough prior to the sheeting of the dough.
Claim 2
Dependent Claim
138 words
In a process for the preparation of a comestible product which includes the steps of: (a) preparing a dough of pregelatinized starch, a dry flaked or powdered cereal or flakes of a starchy vegetable, vegetable oil, water, sugar and salt; (b) sheeting the dough; (c) cutting the sheeted dough to produce a shaped chip; (d) frying the shaped chip in fat or oil; and (e) seasoning the fried product, the improvements in the process comprising; forming a suspension of lecithin in water, the amount of lecithin being at least 0.02% of the weight of the pregelatinized starch and dry flaked or powdered cereal or flakes of starchy vegetable, and less than an amount in which the sheeted dough becomes lacy and breakage occurs, and adding the lecithin suspension to the dough prior to the sheeting of the dough.
Claim 3
Dependent Claim
26 words
A process as in claim 1 wherein the lecithin is added in a range of 0.2 to 0.25% of the dry weight of the dough ingredients.
Claim 4
Dependent Claim
16 words
The process of claim 2 in which the flakes of a starchy vegetable are potato flakes.
Claim 5
Dependent Claim
14 words
The process of claim 2 in which the dry flaked cereal is corn flakes.
Claim 6
Dependent Claim
14 words
The process of claim 2 in which the dry flaked cereal is wheat flakes.
Claim 7
Dependent Claim
11 words
A product made in accordance with the process of claim 1.
Claim 8
Dependent Claim
50 words
A process for producing a dough which, when fried, resembles a potato chip, comprising mixing potato flakes, pregelatinized starch, edible oil, water, seasoning, and a soybean lecithin suspension in water wherein the concentration of soybean lecithin is between about 0.2 and 0.7% of the dry weight of the dough ingredients.
Claim 9
Dependent Claim
50 words
A process for producing a dough which, when fried, resembles a potato chip, comprising mixing potato flakes, pregelatinized starch, edible oil, water, seasoning, and a soybean lecithin suspension in water wherein the concentration of soybean lecithin is between about 0.2 and 0.7% of the dry weight of the dough ingredients.
Claim 10
Dependent Claim
72 words
A process for making a dough which is to be fried to produce a comestible snack food comprising preparing a suspension of vegetable-derived lecithin in water and adding the lecithin in water suspension to a dough containing pregelatinized starch, flaked potato particles, edible oil, water and seasoning in an amount such that the lecithin concentration in the dough is from about 0.2 to 0.7% of the dry weight of the dough ingredients.
Claim 11
Dependent Claim
72 words
A process for making a dough which is to be fried to produce a comestible snack food comprising preparing a suspension of vegetable-derived lecithin in water and adding the lecithin in water suspension to a dough containing pregelatinized starch, flaked potato particles, edible oil, water and seasoning in an amount such that the lecithin concentration in the dough is from about 0.2 to 0.7% of the dry weight of the dough ingredients.
Claim 12
Dependent Claim
53 words
A process for improving the flow characteristics and thickness of a mixed dough containing pregelatinized starch and cereal comprising adding a lecithin-in-water suspension to the dough ingredients during mixing of the dough, the amount of lecithin in the lecithin-in-water suspension being about 0.2 to 0.7% of the dry weight of the dough ingredients.
Claim 13
Dependent Claim
53 words
A process for improving the flow characteristics and thickness of a mixed dough containing pregelatinized starch and cereal comprising adding a lecithin-in-water suspension to the dough ingredients during mixing of the dough, the amount of lecithin in the lecithin-in-water suspension being about 0.2 to 0.7% of the dry weight of the dough ingredients.
