Abstract
Abstract A snack food is prepared from an extrudable mixture, containing dehydrated potato, baking powder, mono- and diglycerides of fatty acids and water, which is extruded as a flat sheet through a sheeting die with a narrow opening, cut into pieces of predetermined size and shape and baked, the composition of the dehydrated potato, the proportion of the baking powder, the size of the opening in the sheeting die, the cutting of the sheet and the temperature and time of baking being controlled to produce a shaped, hollow potato snack in which the sides are entirely enclosed, with the top and bottom being formed from the top and bottom of said cut sheet, and a cross section of said top and bottom being approximately one-half of the thickness of said cut sheet.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
168 words
A process of producing a shaped snack product which comprises preparing a finely divided solid mixture of baking powder and dehydrated potato, said dehydrated potato containing a minor proportion by weight of fatty acid glyceride consisting essentially of mono- and diglycerides of fatty acids, said mixture optionally including a minor amount of a seasoning agent which does not destroy puffing, adding sufficient water to form an extrudable dough mixture, forming said dough mixture into a flat sheet, cuttng pieces of predetermined size and shape from said sheet and baking said pieces, the composition of the dehydrated potato, the kind and proportion of the baking powder, the thickness of said pieces and the temperature and time of baking being controlled to produce a shaped, hollow potato product in which the sides are entirely enclosed, with the top and bottom being formed from the top and bottom of said cut pieces, and a cross section of said top and bottom being approximately one-half of the thickness of said cut pieces.
Claim 2
Dependent Claim
168 words
A process of producing a shaped snack product which comprises preparing a finely divided solid mixture of baking powder and dehydrated potato, said dehydrated potato containing a minor proportion by weight of fatty acid glyceride consisting essentially of mono- and diglycerides of fatty acids, said mixture optionally including a minor amount of a seasoning agent which does not destroy puffing, adding sufficient water to form an extrudable dough mixture, forming said dough mixture into a flat sheet, cuttng pieces of predetermined size and shape from said sheet and baking said pieces, the composition of the dehydrated potato, the kind and proportion of the baking powder, the thickness of said pieces and the temperature and time of baking being controlled to produce a shaped, hollow potato product in which the sides are entirely enclosed, with the top and bottom being formed from the top and bottom of said cut pieces, and a cross section of said top and bottom being approximately one-half of the thickness of said cut pieces.
Claim 3
Dependent Claim
96 words
A process as claimed in claim 1 in which said finely divided solid mixture, prior to adding water to form an extrudable dough mixture, contains at least approximately 96% by weight dehydrated potato, said dehydrated potato containing 0.05 to 1.50% by weight of said mono- and diglycerides of fatty acids, said mixture also containing a minor proportion of baking powder within the range of about 1% to 2% by weight of said mixture, a minor proportion by weight of said mixture, of salt and optionally a minor proportion, by weight of said mixture, of caramel color.
Claim 4
Dependent Claim
23 words
A process as claimed in claim 1 in which approximately 10-40% by weight of said dehydrated potato is replaced by degermed corn flour.
Claim 5
Dependent Claim
19 words
A process as claimed in claim 1 in which the wall thickness of said pieces is approximately 0.032 inch.
Claim 6
Dependent Claim
25 words
A process as claimed in claim 1 in which the wall thickness of the resultant product is within the range of 0.1 to 1 millimeter.
Claim 7
Dependent Claim
67 words
A baked, shaped snack product having wall sections completely enclosing a hollow space, said product comprising dehydrated potato, containing a minor amount of fatty acid glyceride consisting essentially of mono- and diglycerides of fatty acids, a minor amount of baking powder residue resulting from the reaction of sodium bicarbonate with an acid phosphate, and optionally a minor amount of a seasoning agent which does not destroy puffing.
Claim 8
Dependent Claim
67 words
A baked, shaped snack product having wall sections completely enclosing a hollow space, said product comprising dehydrated potato, containing a minor amount of fatty acid glyceride consisting essentially of mono- and diglycerides of fatty acids, a minor amount of baking powder residue resulting from the reaction of sodium bicarbonate with an acid phosphate, and optionally a minor amount of a seasoning agent which does not destroy puffing.
Claim 9
Dependent Claim
21 words
A baked, shaped snack product as claimed in claim 6 containing at least approximately 96% by weight of said dehydrated potato.
Claim 10
Dependent Claim
44 words
A baked, shaped snack product as claimed in claim 6 containing at least approximately 96% by weight of a mixture of said dehydrated potato and degermed corn flour, said degermed corn flour being present in said mixture in an amount of 10-40% by weight.
