Description
The present invention relates to a method for producing spaghetti raw noodles, comprising the steps of: mixing a common wheat flour, acetic acid starch, corn starch, egg white, egg yolk, whey, cinnar, freimol and water to form a dough; And molding the surface of the dough by multi-step extrusion.
In modern society, there is an increasing demand for a simple formula that can be substituted for stocks due to busy daily life. The annual per capita consumption of wheat is second only to rice, and the percentage of processed food using wheat is the highest at 33.9%. In recent years, the population of Korea enjoys and uses the food of various countries with the change of the social environment and the lifestyle. Therefore, the food culture centering on Western cuisine has developed rapidly, and among them, The proportion is very high. For domestic consumers, Italian spaghetti is perceived to be as comfortable and friendly as noodles, and the proportion of pasta in noodle sales is increasing. In addition, whole wheat pasta is popular with consumers who are considering health consciousness, and the pasta-related market is expected to grow steadily every year, as manufacturers are upgrading the material level to meet the demands of consumers who are seeking to become more sophisticated.
Spaghetti is usually produced and distributed in the form of noodles and dry noodles. In the western and northern regions of the country, the use of fresh and tasty soft-noodle spaghetti is common. In the case of Japan, which has a lot of cotton consumption, the noodle market has already formed a mature stage market. Noodles are mainly sold for commercial use, and demand for general households is increasing due to the simplicity of cooking, excellent quality and price competitiveness. In Korea, spaghetti noodles, which should be refrigerated, are preferred by enthusiasts who are seeking higher quality and flavor. Although the market size is still small, the interest of the public is increasing. As more people are looking for pasta to enjoy different tastes from oriental noodle dishes, the market trend is to prefer chilled spaghetti, which is richer and less processed than real dried pasta. As the awareness of ramen as an anti-wellness food has expanded, the development and consumption of various noodle products such as udon, cold noodle, kalguksu, and Chinese noodles have been on the rise. Among them, spaghetti has a production status of about 20%, and the size of the noodle market is increasing every year. Spaghetti noodles have a short cooking time. The noodles have a short market time and smooth taste. They can enhance various colors, shape and nutrition according to the addition of the ingredients.
The currently marketed spaghetti noodles are manufactured using semolina, which is made by grinding a durum wheat embryo with a lot of gluten, and it is disadvantageous that the expensive price of durum wheat and the distribution difficulty .

Also, in case of domestic products, spaghetti noodles made with imported DURUM wheat are circulated. . In addition, spaghetti consumption in the form of a dry surface occupies the majority because of convenience of storage and distribution. This is because domestic noodle technology can not produce the texture of Italian spaghetti that consumers want. Therefore, if you develop noodle spaghetti using ordinary flour instead of expensive durum wheat, this could be a cost-effective product that reflects consumer convenience and trends.

The texture of the FA, FB, FC, and FD prepared in Example 5-1 and the GA and GB mixed spaghetti noodles prepared in Example 5-3 were measured and compared at the same time, showing that acetic acid starch and egg white affects the texture of the cotton To investigate the effect. The results of the texture evaluation of the six spaghetti noodles are shown in Table 13 below.
As a result, as shown in Table 13, the hardness, gumminess, and chewiness were higher as the egg white addition amount was higher, and adhesiveness, springiness, and cohesiveness (cohesiveness) did not show any difference according to the addition of egg white. On the other hand, there was no difference in the degree of texture by the addition amount of acetic acid starch. Therefore, it was found that the addition of egg white affects the hardness, gumminess and chewiness of spaghetti noodles.
Furthermore, in order to analyze whether the above-mentioned results affect the sensory preference, the sensory evaluation was performed on the hardness, elasticity, flavor and overall acceptability of the spaghetti noodles of the above-mentioned six combinations.
As a result, as shown in Fig. 5, good results were obtained in the case of FB (5 g of acetic acid starch, 3 g of egg white) and GA (5 g of acetic acid starch, 2 g of egg white) in terms of hardness, elasticity and overall acceptability. The results of the sensory evaluation showed that the egg white content did not significantly affect the sensory factors. Based on the above results, 5 g of acetic acid starch and 2 g of egg white were selected as the optimum composition ratios of spaghetti noodles.
Example 6. Setting egg yolk addition
6-1. Spaghetti with different amounts of yolk (0, 1.08, 2.08, 3.08 g) Raw Produce
Following the setting of the addition amount of the acetic acid starch and the egg white in Example 5, spaghetti noodles were prepared by varying the addition amount of egg yolk at 1.08, 2.08 and 3.08 g in order to improve the texture and to prevent the dissolution of the surface starch, Respectively.
6-2. Spaghetti with different amounts of yolk (0, 1.08, 2.08, 3.08 g) Raw Measurement of turbidity, texture and sensory evaluation
The absorbance of the cooked water was measured in order to measure the turbidity of spaghetti noodles prepared by varying the addition amount of yolk. The results are shown in Table 15 below.
As a result, the turbidity of GA-mixed spaghetti noodles without egg yolk was measured to be 0.27 ± 0.02, whereas the egg yolk added HA, HB and HC spaghetti noodles had turbidity of 0.25 ± 0.01, 0.24 ± 0.02 , 0.25 ± 0.04, which was lower than that of GA combination. From the above results, it was confirmed that the addition of egg yolk had an effect on preventing the dissolution of surface starch during the cooking of spaghetti noodles.
The texture of the four mixed spaghetti noodles was measured and the results are shown in Table 16 below.
As a result, the hardness value was highest in the spaghetti noodles of HA containing 1.08 g of egg yolk added and 2.08 g, 3.08 g and 0 g of egg yolk were added. In the gumminess items, HA and HB showed slightly higher values and chewiness was slightly higher in HB.
Finally, the spaghetti noodles of the above four ingredients were subjected to a sensory test for hardness, elasticity, flavor and overall acceptability.
As a result, as shown in Fig. 6, all of the above four items showed the highest value in spaghetti noodles containing HA added with 1.08 g of egg yolk, and received the best evaluation. Therefore, we carried out the next step based on the best evaluation of HA spaghetti noodles mixed with turbidity, texture and sensory evaluation results.
Example 7. Whey Setting of addition amount
7-1. Whey (0, 1, 3, 5, 7g) Spaghetti with different additions Raw Produce
In order to improve the texture and texture of the surface of HA spaghetti prepared by the results of Example 6, whey proteins were selected and added. As a result of the preliminary experiment, the spaghetti added with 10% or more of whey protein was difficult to prepare with dough, so that the spaghetti noodles were added at 10% or less.
7-2. Whey (0, 1, 3, 5, 7g) Spaghetti with different additions Raw Measurement of turbidity, texture and sensory evaluation
The absorbance of the cooked water was measured to measure the turbidity of HA, IA, IB, IC, and ID noodle spaghetti prepared in Example 7-1, and is shown in Table 18 below.
As a result, the turbidity of whey protein added spaghetti noodles was lowered to an average of about 0.21 ± 0.03 compared to that of HA without added whey protein. Therefore, it was confirmed that the addition of whey protein affects the prevention of surface starch elution during cooking of spaghetti noodles. In addition, when the spaghetti noodles prepared by the multi-stage extrusion method were compared with those of the conventional spaghetti preparation method, turbidity was generally lower than that of the conventional spaghetti manufacturing method. Therefore, the production of spaghetti surface by the multi- .
Next, the texture of the five types of spaghetti noodles was measured and shown in Table 19 below.
As a result, the hardness increased as the addition amount of whey protein increased, and the ID hardness was the highest. The springiness showed no significant difference until addition of 3 g of whey protein, but decreased when 5 g and 7 g of whey protein were added.
As a result of the functional test on the spaghetti noodles of the above five combinations, ID spaghetti added with 7 g whey protein was the highest in hardness, IB, 1 g and 5 g whey protein added with 3 g , Followed by IA, IC, and HA not added. Resilience was the highest score for IB spaghetti, and flavor did not show any significant difference in all samples. IB spaghetti with 3 g of whey protein was the highest score in overall acceptance, followed by IA spaghetti with 1 g whey protein. However, adding more than 5g of whey protein did not easily clump the dough in the spaghetti manufacturing process.
7-3. Using common wheat flour Durham Mill Substitute spaghetti Raw Optimum mixing ratio
Through the steps of Examples 2 to 7-2, the optimal conditions for preparing spaghetti noodles using general wheat flour were determined by changing the kinds and amounts of the additive materials. The optimum amount of starches, the degree of starch elution, the degree of texture, and the sensory evaluation were measured to determine the optimum ingredients and the optimum compounding ratio. The results are shown in Table 20 below.
Furthermore, the experiment was conducted to determine the optimum mixing ratio of spaghetti noodles by developing the optimization technique of multi - stage extrusion process.
Example 8. Optimal Multi-stage extrusion Technical temperature setting
8-1. optimal
Multi-stage extrusion
Technical
Based on the results of Example 7-2, an attempt was made to set the optimum temperature conditions for the multi-stage extrusion process to produce spaghetti noodles having the properties of commercial spaghetti noodles.
Spaghetti raw noodles were prepared by setting the multi-stage extrusion temperatures at 90 ° C or 100 ° C for the FB and GA blends prepared in Examples 5-1 and 5-3, respectively. The hardness was measured and the sensory test was performed to confirm the texture of the prepared surface. The results are shown in Tables 21 and 8, respectively.
As a result of hardness measurement, the hardness of each of the multi-stage extruded spaghetti noodles (FB90, GA90, FB100, GA100) prepared under the above conditions did not show a large difference from the hardness of spaghetti noodles FB and GA without multi-stage extrusion.
As a result of sensory evaluation with regard to appearance, hardness, texture, and overall preference, spaghetti noodles with multi - stage extrusion were evaluated better than all noodles without multi - stage extrusion, and the appearance and texture were improved received. However, there was no significant difference according to the setting temperature of multi - stage extrusion. Therefore, since the sensory test results at 90 ℃ and 100 ℃ were similar to each other, the set temperature was lowered to perform multi - stage extrusion.
8-2. optimal
Multi-stage extrusion
Technical
Optimum Multistage Extrusion Technology Temperature Setting The results of the first stage test showed that the sensory test results for 90 ° C and 100 ° C were similar to each other and that the two types of formulations IA and IB shown in Example 7-3, The multi - stage extrusion process was performed under three different temperature conditions. IA and IB were extruded at 70 ° C, 80 ° C and 90 ° C, respectively, to prepare spaghetti noodles. The hardness was measured and the sensory evaluation was carried out. The results are shown in Table 22 and FIG.
As a result of hardness measurement, the hardness of raw noodles of multi - stage extruded spaghetti did not show big difference according to temperature in both IA and IB combination. When the hardness of the combination of IA and IB at the same set temperature was compared, hardness of IA mixed spaghetti noodles with 1 g of whey was higher.
As a result of the sensory evaluation with regard to the hardness, elasticity, flavor and overall acceptability, as shown in Fig. 9, it was found that the noodles of the IB mixture containing 3 g of whey protein Spaghetti overall got a better rating. The results showed that the mechanical hardness of spaghetti noodles was higher in the case of adding 1 g of whey, but in the case of sensory evaluation, the spaghetti noodles added with 3 g of whey in all items were better evaluated, , And the mixing condition of the spaghetti side was determined by the IB formulation in which 3 g of whey was added.
Example 9. Optimal Multi-stage extrusion Technical pressure setting
In the temperature setting experiment of Example 8, the feeder speed was varied between A: 5 and 6, which is the speed of producing cereal grains using a multi-stage extruder. As shown in FIG. 10, the substrate is adjusted to adjust the speed of the cotton yarn feeder, and when the cotton yarn is inserted into the cotton yarn feeder, the amount of the kneaded yarn is passed through the feeding opening by the cotton yarn feeder speed.
The results of Example 8 show that the IB extrusion temperature was set at 90 ° C for the final formulation of IB and then the speed of the cotton applicator was set to A: 5-6, B: 6-7, or C: 7-8 The spaghetti noodles were prepared, and then hardness and sensory evaluation were carried out. The results are shown in Table 23 and FIG.
As a result of hardness measurement, the hardness values of 29.007 were similar to each other in all three cases irrespective of the speed of the cotton applicator. In addition, sensory evaluation was carried out with regard to hardness, elasticity, flavor and overall preference.
From the above results, the pressure condition of the multi-stage extruder had little effect on the texture and sensory evaluation of spaghetti noodles. However, when the cotton applicator speed is higher than the B level in the process of manufacturing the cotton, the speed of the feeding machine is high, so that the application time of the heating part and the cooling part is shortened to a part of the screw housing of the noodle manufacturing apparatus, I could. In this case, the optimum pressure condition of the multi-stage extruder was set to the optimal condition for the IB compounding determined in this example, that is, the stepper speed of the stepper during the production of spaghetti,
Example 10. Spaghetti cotton wool Verification of quality characteristics of prototype
The optimum spaghetti noodles mixing conditions (IB) and the multi-stage extrusion technology temperature and pressure were set through the steps of Examples 2 to 9, so that the spaghetti noodles were produced as prototypes under the above conditions, and the marketability Respectively.
10-1. Scanning electron microscopy (SEM) SEM ) observe
In order to compare the quality with the prototype produced in this example, we tried to observe the surface and cross-sectional structure of the pre-boiled and boiled post-boiled surface using commercially available semolina or dry surface as a control group. The dough of the two products was frozen at -20 ° C for 24 hours, lyophilized and cut to a size of 0.3 × 0.3 × 0.3 cm or less. The sample was plated at 200 A on an aluminum sample support and observed at a magnification of 100 times, 500 times, 1000 times and 2000 times at an acceleration voltage of 15 kV using a scanning electron microscope (S-3400N, Hitachi, LTD, JAPAN) .
As a result, as shown in Fig. 12A, the surface structure of the prototype product before cooking and the spaghetti surface of the control group were totally uneven and rough, while the surface structure of the prototype after cooking and the control group had a small pore structure And there was no significant difference between the two sides.
Also, as shown in Fig. 13, the comparison of the preprocedural cross-sectional structures of the prototype and the control spaghetti surface showed that the prototype had more pores than the control, while the control group had a very dense structure and had a less pore and smooth shape. This difference was due to the difference between the extrusion condition and the drying condition, and it seemed that the control spaghetti was dry surface and the water content was low. The cross-sectional structures of the two products after cooking are shown in Fig. 14, and the cross-sectional structures of the prototype and the control group were observed to be very similar. This homogeneous structure appeared to be due to the protein-starch matrix formation due to the luxury of cooking.
10-2. Verification of dough characteristics of prototype
The pH, water activity, and chromaticity were measured to verify the characteristics of the prototype and the control (semolina or dry) dough produced in this example.
For pH measurement, the prototype and control dough were cut and mixed with 100 ml of distilled water. The mixture was shaken at 120 rpm for 30 minutes with a shaker (Lab Companion Model SI-600R, Jeio Tech Inc., Seoul) pH meter, Beckman Coulter Inc., CA, USA).
The water activity was measured by cutting three grams of the prototype product, pulverizing the sample evenly, and measuring the water activity three times using a water activity meter (Novasina, Novasina Ltd, Switzerland).
The chromaticity measurements were performed with a colorimeter (UltraScan PRO, HunterLab, Virginia, USA) after cutting the face plate of the prototype dough into 2.0 cm x 2.0 cm, and the respective chromaticity values were expressed as L *, a * and b * values. The standard white plate used was L * = 94.42, a * = - 0.81 and b * = 1.66. The results of measurement of pH, water activity, and chromaticity according to the above method are shown in Table 24 below.
(Aw)
As shown in Table 24, when the pH was measured, the pH of the prototype was significantly higher than that of the control. Water activity did not show significant difference between prototype and control group. Finally, the L value indicating brightness was significantly higher in the prototype than the control, and the a value indicating the redness and the b value indicating the yellowness were significantly higher in the control group than the prototype.
10-3. Prototype Cooking Property verification
In order to verify the cooking characteristics of the prototype manufactured in this Example, the initial gelatinization temperature and viscosity were measured as a control group, together with the sesolinia, dry and hard-boiled surface, and the results are shown in Table 25 and FIG.

As shown in Table 25 above, the initial pasting temperature of the prototype and the control group was measured. As a result, no significant difference was observed between the prototype and the control group. Generally, the initial gelatinization temperature indicates the minimum temperature required for gelatinization. When the main ingredient is replaced with another ingredient, starch swelling around the starch particles due to protein or fat may be delayed. For this reason, It is known that the glowing temperature is increased. However, all of the above results confirmed that they have similar initial gelation temperatures.
The viscosity of the prototype and the control spaghetti surface was also measured. Peak viscosity refers to the highest viscosity seen during the process of starch digestion and indicates the ability to hydrolyze starch. The peak viscosity is also correlated with the quality of the final product. When the substitute having a high water absorption rate is added to the flour, the substitute first occupies water to increase the peak viscosity. When the peak viscosity is too low, And taste. The highest peak was found in the order of prototype and strong and dry. The prototype was found to have a higher peak viscosity than that of Semolina but it was higher than that of high strength. Therefore, the prototype was thought to have a texture and texture similar to that of the strong surface. Next, the holding strength was measured at 95 ° C, and then the prototype was measured at the lowest level. The break down value obtained by subtracting the lowest point from the peak point was higher than that of the prototype but not significantly different from the semolina or dry surface. The large break down value means that the starch has a poor processability because it means that the luxed point receives the shear force and the stability is broken. The final viscosity values were highest for the three molybdenum surfaces and the lowest for the prototype. Finally, the set back value for predicting the degree of aging was significantly higher in semolina and dry surface, followed by prototype and strong texture.
10-4. Surface starch Elution property Measure
In order to measure the surface starch elution property of the prototype prepared in the examples of the present invention, CJ freshian spaghetti was used as a control group for the control, and the prototype was cooked for 3 minutes and the control group was cooked for 4 minutes as described on the wrapping paper. , Water absorption rate, and turbidity are shown in Table 26 below.
(at 674 nm)
As a result of measuring volume change of prototype and control group, volume change of control group was measured to be larger, and volume of cooking surface was positively correlated with weight of cooking surface, so that weight of control group was also higher. These differences are considered to be due to the difference in moisture absorption between the control and the prototype at 4 and 3 minutes, respectively. As a result of measuring the moisture absorption rate of the cooked surface, there was no significant difference between the moisture absorption rate of the prototype and the control. Turbidity, a measure of the degree of loss of cooked surface solids, was not significantly different between the prototype and control group.
10-5. Cotton Fire Measure
In order to measure the non-negative state of the prototype prepared in the example of the present invention and the control group CJ Presian spaghetti, weight and length changes were measured by time after each side was boiled. The results are shown in Tables 27 and 28, respectively . The capital letters shown in the table below mean significant difference between samples, and lower case means significant difference in boiling time.
As a result of measuring the weight change of the two products, there was no significant difference between the two products after boiling the prototype and control spaghetti sides for 1 minute and 2 minutes. However, there was a significant difference between the prototype and the control group after 3 minutes of boiling, and the weight change of the control group was significantly higher than that of the prototype when boiled for 5 minutes. The weight change with time of boiling was significantly increased after 3 minutes of boiling in the case of prototype, and the weight of control increased significantly after 2 minutes of boiling.
Next, the change in length after boiling the two products was significantly higher in the control group than in the prototype at all times from 1 minute to 5 minutes after boiling. In the case of the prototype, the length change was significantly increased after one minute of boiling and the length of the control group was significantly increased from 2 minutes after boiling.
10-6. Physical property measurement
The hardness, elasticity and gumminess of the prototype and the control group CJ Presian spaghetti were measured to compare their physical properties. The measurement results are shown in Table 29 below.
The hardness of the prototype was significantly higher than that of the control. In the case of elasticity and gingiva, the prototype and the control group showed almost the same value.
10-7. Sensory test
Finally, the sensory evaluation was performed on the appearance, flavor, taste, hardness, elasticity, chewiness, and overall acceptability of the prototype and the control (Semolina or dry surface). The sensory test was carried out for the expert panel and the general consumer, respectively, and the results are shown in Tables 30 and 31 below.

As a result of the sensory test of the expert panel, as shown in Table 30, the appearance of the prototype was higher than that of the control, but no significant difference was observed. In the fragrance, taste, hardness and elasticity items, the prototype was slightly higher than the control group, but the difference was not significant. On the other hand, Kochum and overall acceptability showed higher values than the control, Semolina spaghetti dry surface, but no significant difference. As a result of sensory evaluation of the expert panel, there was no significant difference between the two products in terms of appearance, flavor, taste, hardness, elasticity, chewiness and overall acceptability. Thus, the spaghetti noodles prepared through the examples of the present invention, And it was evaluated as a product with no significant difference.
As a result of the sensory test on the general consumer panel, as shown in Table 31, the appearance of the prototype was significantly more favored than that of the control group. In the fragrance, taste, hardness, elasticity, Kosi degree, general preference items, the control group, Semolina noodles, got higher score than the prototype, but showed no significant difference.
