Abstract
Abstract A readily water-miscible powder-form amylaceous food product is prepared by a process in which a first mixture of amylaceous material and water is prepared, cooked and liquefied by enzymatic hydrolysis, a second mixture of amylaceous material, water and at least part of the liquefied first mixture is prepared, cooked, liquefied by enzymatic hydrolysis and at least part thereof is spray dried. The product obtained is a powder suitable for soups, acidic beverages or instant breakfasts.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
95 words
A process for the production of a readily water-miscible powder-form amylaceous food product which comprises preparing a first mixture of amylaceous material and water, cooking the mixture to cause gelatinization of the amylaceous material and liquefying it by enzymatic hydrolysis, preparing a second mixture having a dry matter content of from 35% to 45% by weight of additional amylaceous material, water and at least 40% by weight of the first liquefied mixture, cooking the mixture to cause gelatinization of the additional amylaceous material, liquefying it by enzymatic hydrolysis and spray drying at least part thereof.
Claim 2
Dependent Claim
95 words
A process for the production of a readily water-miscible powder-form amylaceous food product which comprises preparing a first mixture of amylaceous material and water, cooking the mixture to cause gelatinization of the amylaceous material and liquefying it by enzymatic hydrolysis, preparing a second mixture having a dry matter content of from 35% to 45% by weight of additional amylaceous material, water and at least 40% by weight of the first liquefied mixture, cooking the mixture to cause gelatinization of the additional amylaceous material, liquefying it by enzymatic hydrolysis and spray drying at least part thereof.
Claim 3
Dependent Claim
29 words
A process as claimed in claim 1, which is carried out continuously, part of the liquefied mixture being recycled to the stage of mixing of amylaceous material and water.
Claim 4
Dependent Claim
26 words
A process as claimed in claim 1, wherein the amylaceous material is a meal, a flour or a starch of a cereal or mixture of cereals.
Claim 5
Dependent Claim
18 words
A process as claimed in claim 3, wherein the cereal is wheat, barley, oats, rye, rice and/or maize.
Claim 6
Dependent Claim
28 words
A process as claimed in claim 1, wherein the amylaceous material consists of meal or flour of wheat, rye and oats in a ratio by weight of 80:10:10.
Claim 7
Dependent Claim
23 words
A process as claimed in claim 1, wherein the first mixture has a dry matter content of from 25 to 35% by weight.
Claim 8
Dependent Claim
39 words
A process as claimed in claim 1, wherein the first and/or second mixture is cooked by the injection of steam to a temperature of from 130° to 160° C. and kept at that temperature for 15 to 60 s.
Claim 9
Dependent Claim
23 words
A process as claimed in claim 1, wherein after cooking, the first and/or second mixture is cooled to the hydrolysis temperature by expansion.
Claim 10
Dependent Claim
26 words
A process as claimed in claim 1, wherein hydrolysis is carried out with malt diastase at a temperature in the range from 50° to 90° C.
Claim 11
Dependent Claim
27 words
A process as claimed in claim 1, wherein at least part of the liquefied second mixture is sterilized by the injection of steam before being spray dried.
Claim 12
Dependent Claim
20 words
A process as claimed in claim 10, wherein a fat is added to the liquefied mixture before it is sterilized.
Claim 13
Dependent Claim
34 words
A process as claimed in claim 10, wherein lactose is added to the mixture before it is sterilized and the mixture is subjected to fermentation by lactic bacteria after sterilization and before spray drying.
Claim 14
Dependent Claim
14 words
A readily water-miscible powder-form cereal food product prepared by the process of claim 1.
Claim 15
Dependent Claim
101 words
A process for the production of a readily water-miscible powder-form cereal food product which comprises preparing a first mixture of cereal flour and water, cooking the mixture to cause gelatinization of starch within the cereal flour and liquefying the mixture by enzymatic hydrolysis, preparing a second mixture having a dry matter content of from 35% to 45% by weight of additional cereal flour, water and at least 40% by weight of the first liquefied mixture, cooking the mixture to cause gelatinization of starch within the additional cereal flour, liquefying the mixture by enzymatic hydrolysis and spray drying at least part thereof.
Claim 16
Dependent Claim
101 words
A process for the production of a readily water-miscible powder-form cereal food product which comprises preparing a first mixture of cereal flour and water, cooking the mixture to cause gelatinization of starch within the cereal flour and liquefying the mixture by enzymatic hydrolysis, preparing a second mixture having a dry matter content of from 35% to 45% by weight of additional cereal flour, water and at least 40% by weight of the first liquefied mixture, cooking the mixture to cause gelatinization of starch within the additional cereal flour, liquefying the mixture by enzymatic hydrolysis and spray drying at least part thereof.
