Abstract
Abstract Instant-cooking dry macaroni products are manufactured by preparing a raw macaroni or like macaroni type food material containing at least 25% by weight of water by mixing, with substantially no kneading, components consisting mainly of wheat flour and water or additives; then subjecting this mixture to a preliminary steaming at a gauge pressure of 0.5-1.5 kg/cm 2 for 2-5 minutes till an α-conversion degree of from 60% to 80% is reached; then shaping the resulting material into individual molded pieces of a desired configuration; thereafter, with or without application of water to the surfaces of the molded pieces so that these surfaces carry water in an amount not exceeding 100% by weight relative to the weight of the molded pieces; then subjecting the molded pieces to a further steaming step at similar pressure and time till an α-conversion degree of at least 90% is attained; and thereafter drying them till the water content of the molded pieces is reduced to at most 10% by weight relative to the weight of the molded pieces thus dried. These dry macaroni products have no portions sticking to each other, have smooth surfaces and have fine porous texture, and are easily transformed to an edible cooked state by immersion in hot water for a short time, and give good sense, feel and taste. Also, these dry foods are stable and have good durability without change in quality during storage for an extended period of time.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
162 words
A method of manufacturing instant-cooking dry macaroni products, comprising the steps of: (a) preparing a mixture containing from 25 to 35% by weight of water by mixing, with substantially no kneading, a starting material consisting essentially of a starch-containing component selected from wheat flour and wheat flour with other grain powders, starch or both and of water; then (b) subjecting the mixture of step (a) to a preliminary steaming step until said starch attains an α-conversion degree of from 60% to 80% as measured by the diastase enzyme process; then (c) shaping the resulting material into individual molded pieces of a desired configuration; thereafter (d) subjecting the molded pieces to a further steaming step until said starch attains an α-conversion degree of at least 90%; and then (e) drying the steamed, molded pieces of step (d) until the water content of the molded pieces is reduced to at most 10% by weight relative to the weight of the molded pieces thus dried.
Claim 2
Independent Claim
162 words
A method of manufacturing instant-cooking dry macaroni products, comprising the steps of: (a) preparing a mixture containing from 25 to 35% by weight of water by mixing, with substantially no kneading, a starting material consisting essentially of a starch-containing component selected from wheat flour and wheat flour with other grain powders, starch or both and of water; then (b) subjecting the mixture of step (a) to a preliminary steaming step until said starch attains an α-conversion degree of from 60% to 80% as measured by the diastase enzyme process; then (c) shaping the resulting material into individual molded pieces of a desired configuration; thereafter (d) subjecting the molded pieces to a further steaming step until said starch attains an α-conversion degree of at least 90%; and then (e) drying the steamed, molded pieces of step (d) until the water content of the molded pieces is reduced to at most 10% by weight relative to the weight of the molded pieces thus dried.
Claim 3
Dependent Claim
18 words
A method according to claim 1, in which said shaping step includes extruding said mixture through an extruder.
Claim 4
Dependent Claim
33 words
A method according to claim 1, further comprising the step of applying water to the surfaces of the preliminarily steamed and molded pieces before subjecting them to said further steaming of step (d).
Claim 5
Dependent Claim
20 words
A method according to claim 1, further including the step of granulating the mixture of step (a) after thorough mixing.
Claim 6
Dependent Claim
39 words
A method according to claim 3, in which said application of water causes said surfaces of said molded pieces to carry water thereon in an amount not exceeding 100% by weight relative to the weight of said molded pieces.
Claim 7
Dependent Claim
35 words
A method according to claim 1, further comprising applying an emulsion of an edible oil to the surfaces of the preliminarily steamed and molded pieces before subjecting them to said further steaming of step (d).
Claim 8
Dependent Claim
34 words
A method according to claim 3, in which said water is applied by spraying water through a spray gun; subjecting the molded pieces to a shower system; or immersing the molded pieces in water.
Claim 9
Dependent Claim
36 words
A method according to claim 6, in which said emulsion is applied by spraying said emulsion through a spray gun; subjecting the molded pieces to a shower system; or immersing the molded pieces in said emulsion.
Claim 10
Dependent Claim
