Description

DESCRIPTION
BREADS AND THEIR PRODUCTION
Technical Field
The present invention relates to breads and their production. Particularly, it relates to breads having improved taste and flavor and obtained by uniformly admixing 5'-ribonucleotide salts coated by a fat or oil or the like with wheat flour to be used as the raw material, and their production.
Background Art
Breads are produced by mixing and kneading raw materials such as wheat flour, yeast, salts, sugars, fats and oils, dairy products, eggs and"the like and then subjecting the resulting dough mass to a heat treatment as it is, or after fermentation. In the production of breads, various additives such as L-ascorbic acid and its salts, ammonium chloride, calcium sulfate, fats and oils, surfactants, water-soluble polymers, yeast extract and the like are used for promoting fermentation by yeast, reinforcing network of gluten and improving appearance, texture, flavor and the like.
On the other hand, seasonings such as sodium glutamate, sodium 5'-ribonucleotide and the like have an effect for improving taste and flavor of foods and they have been used in almost all foods. However, they have not been used for the production of breads. In fact, the addition of such seasonings to breads has been considered to be difficult because, if sodium glutamate is -added, breads are liable to cause coloring such as browning during the heat treatment and, in the case of sodium 5'-ribonucleotide, it is degraded by phosphatase in wheat flour during mixing and kneading the raw materials to lose it's seasoning effect.
Because of these reasons, particularly, in cooked breads such as hamburger, hot dog, sandwich, pizza and the like, such seasonings have been used only in filling or topping materials to improve taste and flavor thereof.
Recently, as eating habits have become rich in variety, various breads have been produced and it is requested to improve taste and flavor of .the dough itself to enrich varieties of breads.
Objects of the Invention
One object of the present invention is to provide breads containing 5'-ribonucleotide salts with preventing loss of their seasoning effect.
Another object of the present invention is to provide a process for producing breads containing 5'- ribonucleotide salts with preventing loss of their seasoning effect. These objects as well as other objects and advantages of the present invention will become apparent to those skilled in the art from the following description.
Summary of the Invention
In order to improve taste and flavor of breads, the present inventors have studied intensively. As a result, it has been found that breads having excellent taste and flavor can be obtained by using 5 '-ribonucleotide salts coated by fats and oils and the like in the production of breads according to the conventional method.
That is, it has been found that, when breads are produced by uniformly admixing 5'-ribonucleotide salts coated by fats and oils and the like with wheat flour and processing according to the conventional method, breads having excellent quality and enhanced flavor with minimizing peculiar powdery flavor of wheat flour can be obtained.
According to a present invention, there is provided breads comprising 0.003 to 0.5% by weight of 5'- ribonucleotide salts based on the raw flour material thereof, said 5 '-ribonucleotide salts being distributed throughout the breads.
The present invention also provides a process for producing breads which comprises uniformly admixing a coated preparation of 5 '-ribonucleotide salts with the raw flour material thereof in an amount of 0.003 to 0.5% by weight as 5'-ribonucleotide salts based on the flour
Disclosure of the Invention
The term "breads" used herein means those produced by using wheat flour or rye as main raw materials, optionally adding yeast, salt, sugar, fats and oils, and the like, kneading a mixture of raw materials with water, and then subjecting the resulting dough to heat treatment as it is, or after fermentation. They may be those made by either of "straight dough method" or "sponge dough method". Examples thereof include breads (e.g., white bread, whole wheat bread, graham bread, nugget bread, germ bread, punpani bread, rye bread, corn bread, oatmeal bread, soya bread, rice bread, onion bread, carrot bread, raisin bread, etc.); soft roll breads (e.g., table roll, soft roll, dinner roll, hot dog roll, parker house roll, hamburge.r-buns, butter roll, cheese roll, raisin roll, etc.); hard roll breads (e.g., french bread, german bread, italian bread, winner bread, wiener bread, kaiser-semmel, etc.); Japanese-style confectionery breads (e.g., bean-jam bun, cream bun, jam bun, etc.); confectionery breads (those containing not less than 10 % sugars such as danish pastry, sweet roll, etc.); cooked breads (e.g., ham bread, ham roll, sausage roll, mincemeat roll, pizza, sandwich, hamburger, hot dog, piroshki, etc.) and the like.
The 5'-ribonucleotide salts used in the present invention include, for example, sodium, potassium and calcium salts of 5'-inosinic acid, 5'-guanylic acid, 5'- adenylic acid, 5'-uridylic acid and 5'-cytidylic acid. They are used alone or in combination thereof.
The coated preparation of 5 '-ribonucleotide salts used in the present invention is 5 '-ribonucleotide salts coated with a coating agent.
As the coating agent, fats and oils and/or waxes having a melting point of about 40 to 95°C are used. As the fats and oils, any edible fat or oil having a melting point of about 40 to 95°C can be used. Examples of fats and oils include vegetable or animal fats and oils composed of glycerides (including monoglycerides, diglycerides and triglycerides) and their hydrogenated products. For example, hydrogenated tallow, hydrogenated fish oil, hydrogenated whale oil, hydrogenated rapβseed oil, hydrogenated soybean oil, hydrogenated peanut oil, hydrogenated castor oil, hydrogenated cottonseed oil, hydrogenated safflower oil, hydrogenated rice bran oil and the like can be used.
Waxes used in the present invention include natural waxes such as animal, vegetable and mineral waxes. Examples thereof include candelilla wax, rice bran wax, carnauba wax, beeswax, paraffin wax and the like.
These fats and oils and/or waxes can be used as the main components of the coating agent and are selected depending on a particular kind of breads to be used.
Optionally, it is also effective to formulate fatty acids and/or surfactants within the range of the melting point described above.
-
Fatty acids used in the present invention include straight-chain saturated or unsaturated fatty acids having not less than 12 carbon atoms. For example, there can be used lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linolic acid, arachic acid, arachidonic acid, behenic acid, lignoceric acid and the like.
Further, the surfactant used in the present invention include glycerides (e.g., glycerides, fatty acid esters of glycerol acetic acid, fatty acid esters of glycerol lactic acid, fatty acid esters of glycerol citric acid, fatty acid esters of glycerol succinic acid, fatty acid esters of glycerol diacetyltartaric -acid, glycerol acetic ester, fatty acid esters of polyglycerides, polyglycerol-condensed ricinoleate ester, etc.); sucrose fatty acid esters (e.g., sucrose fatty acid esters, sucrose isobutyrate esters, etc.); sorbitan fatty acid esters, lecithin (e.g., phospholipids including phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, etc.) and the like.
The ratio of the coating agent and fatty acids and/or surfactants optionally added can be freely selected and they can be combined with each other depending on a coating method and a purpose of the resulting coating preparation so that the melting point is suitable for the purpose.
Any of the following coating method can be used. In general, as a method for coating a substance, the following three methods are known. The first method is referred to as "spray-chilling method" (or "spray-cooling method") wherein a substance to be coated (core substance) is suspended in a molten mixture of a fat or oil and/or wax, followed by granulation by spraying with a spray or rotary disc in a cooled gas flow to obtain a coated preparation. For example, fine particles of sodium 5 '-ribonucleotide is added and dispersed in a previously molten coating agent (fat or oil, wax, etc.) at 95°C and then granulation by spraying with a rotary disc or a nozzle in a cooling tower at 25°C.
The second method is referred to as "flow-coating method" wherein a core substance is floated in a gas flow from the lower part of an equipment or fluidized in a coating pan and a fat or oil and/or wax as it is or in the form of a solution in a solvent is sprayed from the upper or side part, followed by cooling or removing the solvent to obtain a coated preparation. For example, there is a method wherein calcium 5 '-ribonucleotide powder is fluidized in a gas flow, followed by granulation by spraying a liquid coating agent (a mixture of a fat or oil, a wax and a surfactant which are previously molten with heating at 90 to 100°C, or stearic acid dissolved in a solvent such as ethyl alcohol heated at 60°C).
The third method is that wherein a core substance is dispersed in a molten fat or oil or wax, followed by solidification with cooling and then grinding to obtain a coated preparation. For example, a method wherein a dispersion liquid of sodium 5'-ribonucleotide obtained in the above first method before spraying is once solidified with cooling, followed by grinding to conduct coating can be employed.
By subjecting the coated preparation thus obtained to double or triple coating with a coating agent having the same or different composition, coating effects can be further enhanced.
The amount of 5'-ribonucleotide .salts thus obtained to be added to breads is 0.003% as sodium 5'-ribonucleotide [0.009% as a coated preparation of calcium 5'-ribonucleotide "Ribocoat EC" (manufactured by Takeda Chemical Industries, Ltd.; containing 35% calcium 5'-ribonucleotide) , or-0.09% as a coated preparation "Ribocoat Powder EC-10K" (manufactured by Takeda Chemical Industries, Ltd.; containing 3.5% calcium 5'-ribonucleotide and 89.4% sodium glutamate) ] to 0.5% [1.43% as "Ribocoat EC", or 14.3% as "Ribocoat Powder EC- 10K"], preferably 0.0035% [0.01% as "Ribocoat EC", or 0.1% as "Ribocoat Powder EC-10K"] to 0.35% [1.0% as "Ribocoat EC", or 10% as "Ribocoat Powder EC-10K"] based on wheat flour as calculated. More preferably, in breads having plain taste, the amount is preferably 0.0035 to 0.175% [0.01 to 0.5% as "Ribocoat EC", or 0.1 to 5.0% as "Ribocoat Powder EC-10K"] and, in breads or cooked breads using fillings such as hamburger-buns, hot dog roll, or breads for pizza or sandwich, etc., the amount is preferably 0.0105 to 0.28% [0.03 to 0.8% as "Ribocoat EC", or 0.3 to 8.0% as "Ribocoat Powder EC-10K"] and, further, for bread crumbs, the amount is preferably 0.0175 to 0.35% [0.05 to 1.0% as "Ribocoat EC", or 0.5 to 10% as "Ribocoat Powder EC-10K"] as calculated in terms of sodium 5'-ribonucleotide. All the percents described above are by weight. In any case, in order to improve flavor, it is effective to use 5'- ribonucleotide salts in combination with sodium glutamate. The preferred ratio is 5 to 30 parts by weight of sodium glutamate per 1 part by weight of 5 '-ribonucleotide salts.
As descried above, according to the present invention, there is provided breads having improved taste and flavor and, thereby, eat habits are rich in variety.
The following Examples further illustrate the present invention in detail but are not to be construed to limit the scope thereof. In the Examples, all "parts" and "percents" are by weight unless otherwise stated. .

Formulation 1 Wheat flour (high gluten flour) 700 g (100 parts) Dry yeast 7 g ( 1 part)
Sugar 28 g ( 4 parts)
Salt 12 g (1.7 parts)
Butter 28 g ( 4 parts)
Skimmed milk 17 g (2.4 parts)
Water - 470 g ( 67 parts)
Coated preparation 2.1 g (0.3 parts)
A coated preparation of calcium 5'-ribonucleotide "Ribocoat Powder EC-10K" (2.1 g) was added to the mixture of the other ingredients followed by kneading with a dough mixer for 20 minutes. The resulting dough was subjected to fermentation at 30°C for 45 minutes, followed by degassing and further fermentation at 30°C for 30 minutes. Then, the dough was molded and subjected to fermentation and then baked at 180°C for 30 minutes to obtain a plain bread (Sample A) .
As a control, a plain bread was obtained according to the same manner as described in the above except that sodium 5'-ribonucleotide "Ribotide Powder 5" (manufactured by Takeda Chemical Industries, Ltd.; containing 95% sodium glutamate; 2.0 g) was used instead of the coated preparation (Sample B) .
Each bread was cooled at room temperature-for 3 hours and then their flavor and taste were tested prganoleptically by 20 panellists, and a residual ratio of 5 '-ribonucleotide was determined. The results are shown in Table 1.
As is seen from Table 1, the plain bread obtained by the process of the present invention (Sample A) was apparently superior in flavor and taste in comparison with Sample B. On the other hand, according to the determination result of 5 '-ribonucleotides, the uncoated sodium 5'- ribonucleotide in Sample B was completely degraded 5'- ribonucleotide, while almost all of 5 '-ribonucleotides in Sample A of the present invention was remained.
