Description

Loosening improver for starch-containing food, starch-containing food and process for producing the same
Technical Field
The invention relates to a loosening improver for starch-containing food, starch-containing food and a preparation method thereof.
Background
Due to the diversification of foods in recent years, the demand for processed foods (seeds) is increasing. In particular, in starch foods such as noodles and rice, processed, cooked products have been sold in large quantities in convenience stores (convenience stores), supermarkets (supermarkets), and the like, and are consumed by many consumers.
In particular, the convenience of processing and the deterioration of quality with the passage of time are problematic in these commercially available processed foods.
Starch-containing food such as noodles and cooked rice flows out to the surface of the food during processing and cooking, and the food is adhered to each other. As a result, in the case of a noodle product, it is difficult to divide the noodle into portions for one meal due to adhesion of noodles to each other, or to mix the noodle with a sauce or a sauce at the time of eating. In the case of instant noodles, the portions where the noodles are stuck are difficult to be boiled. In the case of a cooked rice product, the whole cooked rice cannot be uniformly cooked, and the rice grains are crushed in the rice ball forming machine. Such problems lead to a reduction in production efficiency, an increase in cost, and further lead to the following results: the prepared food is inconvenient to eat, is not delicious and the like.
The prior art of improving the loosening property by eliminating the adhesion between such foods is: a method of mixing or emulsifying fats and oils (patent document 1); a method of adding a sucrose fatty acid ester having a high Hydrophilic Lipophilic Balance (HLB) (patent document 2); a method of adding an organic acid (patent document 3); a food mainly comprising at least one of cereal flour, starch and natural polysaccharides having a gelling ability, characterized in that: coating with a solution containing at least one of gum arabic, pullulan and water-soluble soybean polysaccharides as a main agent (patent document 4); a loosening improving agent obtained by emulsifying a mixture containing an oil and fat, a thickening polysaccharide, and a water-soluble hemicellulose (patent document 5).

Problems to be solved by the invention
However, the techniques of patent documents 1 to 5 have problems such that a sufficient loosening effect cannot be obtained, and also have problems such as deterioration in taste and flavor when an emulsifier is used alone as in patent document 2.
In addition to the problems of loosening and flavor, there is a problem in workability. When the target food is a flour product, for example, when a highly viscous material is used as in patent document 5, the following problems occur: when the improving agent is added to a flour food, it is difficult to uniformly adhere the improving agent to the flour because of its high viscosity. As in patent document 3, when the viscosity of the improver is low, the following problems occur: the improver flows out of the noodles at the time of addition to the noodles, and the improver cannot be added uniformly to the whole noodles or a large amount of the improver must be added.
On the other hand, when the target food is rice, if the viscosity is high when the food is added, there are problems such as the following: when a modifying agent is added as sprinkled water during or before cooking in a steam rice cooker, it is difficult to uniformly adhere the modifying agent to a rice cooker together with a seasoning liquid such as a prepared vinegar, cooking oil, or the like. If the viscosity is low, there are problems that the taste is impaired by moisture absorbed by the rice or that liquid accumulates in the bottom of the container without wrapping the rice when the rice is added after cooking.
Accordingly, an object of the present invention is to provide a loosening improving agent which can be uniformly added to foods such as noodles and cooked rice, has excellent workability, and is used for producing a delicious starch-containing food, while further suppressing the deterioration in quality such as deterioration in loosening properties during storage than before, and to provide a starch-containing food using the loosening improving agent.

For example, the following may be exemplified: a liquid or slurry state in which water-soluble hemicellulose derived from beans, a viscosity modifier, and other auxiliary agents are dissolved in water; a powdery form obtained by simply mixing these components; further granulating the mixture to obtain a granular form.
The loosening improver for starch-containing foods of the present invention can impart good loosening properties when used in the starch-containing foods.
(Water-soluble hemicellulose derived from beans)
The water-soluble hemicellulose derived from beans is obtained from soybeans, red beans, peas, and the like as a raw material, and is preferably soybeans or peas, and more preferably derived from cotyledons, in terms of solubility or industrial properties.
Water-soluble hemicellulose derived from legumes can be obtained using the following method: a method of water extraction or hot water extraction from a hemicellulose-containing raw material; a method of heating and extracting under acid and alkali conditions; extraction by enzymatic decomposition, and the like.
A preferable example of the method for producing water-soluble hemicellulose derived from beans is as follows.
The water-soluble hemicellulose derived from beans can be obtained by subjecting a raw material of beans to pyrolysis under acidic or alkaline conditions, preferably at a pH around the isoelectric point of each protein, at a temperature of preferably 80 ℃ or higher and 130 ℃ or lower, more preferably more than 100 ℃ and 130 ℃ or lower, and then trapping water-soluble components by centrifugation or the like, followed by drying as it is, or by removing hydrophobic substances or low-molecular substances by, for example, activated carbon treatment, resin adsorption treatment, or ethanol precipitation treatment, and drying.
(viscosity modifier)
The viscosity modifier of the present invention may be used in combination with one or more thickeners selected from guar gum, tara gum, locust bean gum, xanthan gum, welan gum, succinyl polysaccharide gum, fermented cellulose, gellan gum, carboxymethyl cellulose and derivatives thereof. It is particularly preferable to use guar gum, tara gum, locust bean gum, xanthan gum, welan gum, succinoglycan gum, and carboxymethyl cellulose, and guar gum, xanthan gum, welan gum, and succinoglycan gum are more preferable.
(method of measuring Carson viscosity and Carson yield value)
The casson yield value is important as an index of the adhesiveness of a preparation solution to a food (the degree of difficulty in the elution of the preparation from the food) when the food is surface-treated with a loosening modifier or the loosening modifier is added to the food, and the casson viscosity is important as an index of the uniform adhesion of the loosening modifier solution to the food.
The measurement of the casson viscosity and the casson yield value according to the present invention can be performed by using a rotary rheometer (lyocell (Rheolab) QC, manufactured by Anton Paar). A cone-shaped measuring jig (CC 39) was attached, a predetermined amount of a modifier solution adjusted to 5 ℃ was introduced into the measuring cup, the shear stress at a shear rate of 0/s to 50/s was recorded, and the Carson viscosity and the Carson yield value were calculated from the Carson calculation formula shown below using the obtained values of the shear rate and the shear stress.

Figure GDA0001973414500000071
(wherein D is a shear rate, s is a shear stress, η) : carson viscosity,. Tau 0 : the casson yield value. )
With respect to the Carson yield value τ 0 The square of the intercept of a primary straight line drawn from the square root of each of two or more shear rates and shear stresses (measured values) is τ 0 . In such a case, it is known that the slope of a straight line obtained by plotting the square root of the shear stress with respect to the square root of the shear velocity (particularly, the high shear velocity region) and the casson viscosity (. Eta.) ) And correspondingly.
The physical properties of the modifier solution at the time of addition or surface treatment are preferably 500 mPas or less in the Carson viscosity and 10 mPas or more in the Carson yield value, more preferably 400 mPas or less in the Carson viscosity and 50 mPas or more in the Carson yield value, and still more preferably 300 mPas or less in the Carson yield value and 100 mPas or more in the Carson yield value. The upper limit of the casson yield value is not particularly limited, and is preferably 1000mPa · s or less.
The amount of the loosening improver of the present invention added to the starch-containing food is preferably 0.01 to 10wt%, more preferably 0.05 wt to 5wt%, and still more preferably 0.1 to 3wt%, based on the amount of the water-soluble hemicellulose added to the starch-containing food.
If the amount of the loosening agent of the present invention added to a starch-containing food is too small, sufficient loosening properties may not be imparted to the starch-containing food, and if too large, the flavor of the starch-containing food may be changed.
The loosening improving agent may have a higher viscosity than a general loosening agent, and thus, if the agent foams, the foams may be difficult to disappear. In the case where bubbles hardly disappear, it is preferable to use an antifoaming agent. Examples of the defoaming agent include silicon, various emulsifiers, and oils and fats.
The loosening improver may be used in combination with other additives as appropriate within a range not affecting the effect of the present invention. Other additives may be listed: emulsifiers such as glycerin fatty acid ester, sorbitan fatty acid ester, stearoyl lactate, polysorbate, and lecithin, oily substances such as general animal fats and oils and tocopherols which are fat-soluble vitamins, monosaccharides such as glucose and fructose (fructose), oligosaccharides such as sucrose, maltose, raffinose (raffinose), maltotriose, trehalose, stachyose, and maltotetraose, proteinaceous substances such as albumin such as sugar alcohol, dextrin, funoran, gelatin, and whey, sodium caseinate, soluble collagen, ovalbumin, yolk powder, and soybean protein, salts such as calcium fortifier, and pH adjusters such as sodium acetate. In addition, polysaccharides such as carrageenan, tamarind gum, gum arabic, curdlan, alginic acid and its derivatives, agar, furcellaran, pullulan, hyaluronic acid, cyclodextrin, chitosan, various starches such as processed starch, and hydrolysates of these polysaccharides may be used in combination.
The loosening improving agent can be distributed and sold in a powdery state, or in a solution state in which the loosening improving agent is added to an organic acid solution such as acetic acid in the form of a solution such as water or a salt solution.
The method for surface-treating the starch-containing food with the loosening improver is not particularly limited, and the following methods are available.
The following methods may be exemplified: (1) The aqueous solution of the loosening improving agent is coated on the food containing starch after heating and cooking to perform surface treatment. (2) The loosening improving agent is sprayed on the heated and cooked starch-containing food. (3) The loosening improving agent is dissolved in a seasoning liquid in advance, and spread on a food containing starch to perform surface treatment. (4) The loosening improver is mixed with powdery seasoning, and spread on a food containing starch to perform surface treatment. These methods are selected according to various food characteristics such as production line and distribution form.
The loosening improving agent can be added into starch-containing food or surface-treated to obtain starch-containing food such as flour and cooked rice with good loosening property. Therefore, the starch-containing food obtained by the present invention is very easy to eat and can be perceived as delicious. In addition, for example, the looseness of refrigerators can be maintained even after the refrigerators are stored for one day after preparation, and the adhesion of starch-containing foods to each other is significantly inhibited.
Further, by imparting good loosening properties, the starch-containing food has excellent processing suitability such as easy mixing and being hardly broken in the production of starch-containing foods.

The present invention will be further described with reference to the following examples, but the present invention is not limited to these examples. In the examples, parts and% are by weight.
In the examples shown below, as the water-soluble hemicellulose derived from beans, a water-soluble soybean hemicellulose derived from soybeans, which is commercially available as "SOYAFIBE) -S" (manufactured by sudoku corporation), was used.
(evaluation of loosening improver) (examples 1 to 4, comparative examples 1 to 5)
According to the formulation shown in Table 1, water-soluble soybean hemicellulose, guar gum (super gum (SUPERGEL) CSA: manufactured by Tri-grammic Co., ltd.), xanthan gum (Sang Aisai (Sun): sanronyu F.F.I. Co., ltd.), welan gum (BIST (Bistop) W: tris Rong Yuan F.F.I. Co., ltd.), succinoglycan gum (Gecko Lin Site succinoglycan-J (GRINDSTED SUCCINOGLYCAN-J): duPont Nutrition Health (DuPont Nutrition And Healthh) Co., ltd.), tamarind gum (Griloid) 3S.
For each modifier, the casson viscosity and the casson yield value were measured by a conventional method. Further, the viscosity was measured with a BM type viscometer at ordinary temperature (20 ℃ C.).
Subsequently, the agents were evaluated for surface looseness. First, 600g of medium gluten flour, 400g of buckwheat flour, 10g of salt and 350g of water were blended, kneaded for 15 minutes by a mixer, rolled and cut according to a conventional method (cutter teeth #22 square, noodle line thickness 1.3 mm) to obtain noodles, the obtained noodles were boiled in boiling water for 2 minutes, and washed with running water for 30 seconds to obtain boiled noodles. Then, 6g of each loosening modifier was uniformly sprayed per 200g of the cooked noodles, filled into a container and sealed, and the loosening property after one day of refrigerator storage was evaluated by 10 functional examiners. Each functional examiner evaluates the test piece according to the criteria in table 2 at 1 to 5 points, and the average value is evaluated as the looseness. If the average score is 4.0 or more, the looseness is judged to be good. In addition, as the evaluation of workability, the case where uniform treatment was easily performed when surface treatment was performed was evaluated as "o", and the case where uniform treatment was difficult was evaluated as "x". The modifier having a good loosening property and an good workability as "O" was judged as a pass.
The evaluation results are shown in table 1.

The modifier added with the viscosity modifier has increased Carson viscosity and Carson yield value, obviously improved looseness and good operability. However, if the casson viscosity is excessively increased, it is difficult to uniformly surface-treat the surface, and workability is deteriorated. Even if the value of the ordinary viscosity measured by the BM type viscometer is about the same, the looseness is insufficient in the case where the casson yield value is low. Further, the modifier having a casson yield value of less than 10mPa · s as in comparative examples 3 to 4 was inferior in the looseness of the face because the adhesiveness of the preparation to the face was lowered. Further, as in comparative example 2, it was confirmed that the surface treatment by dissolving only guar gum was inferior in loosening property of dough, and it was necessary to use a water-soluble hemicellulose derived from beans.
(amount added based on water-soluble hemicellulose) (examples 5 to 8)
The amount of the modifier added was examined. The looseness of the noodles was evaluated in the same manner as in example 1 using the improver D according to the formulation shown in table 3.
The evaluation results are shown in table 3.
(Table 3) formulation Table (%) and results of evaluation of looseness
Figure GDA0001973414500000111
From the results of examples 5 to 8, it was confirmed that when the amount of the loosening improving agent added is 0.01% or more based on the amount of water-soluble hemicellulose added to the starch-containing food, good loosening properties can be imparted.
(evaluation of loosening Property of commercial starch-containing food) (example 9, comparative example 7)
Boiled cassava pearls (tapioca pearls) (processed food of tapioca-derived starch) (Black cassava (GABAN) corporation), which is a commercially available starch-containing food, were boiled in boiling water according to a conventional method to prepare boiled cassava pearls. Then, 5% of modifier D was uniformly added to the cassava pearls in accordance with table 4, and the looseness of the cassava pearls after the refrigerators were stored for one day was evaluated in three grades, i.e., o: loosening, Δ: slightly sticking and difficult to loosen x: clump without loosening. The results of the evaluation of the looseness are shown in table 4.
