Curing: using curing method is stood, under room temperature, preservative film curing 20min is covered on dough, can be made in dough Uniform moisture permeate in flour, good gluten network is formed after mucedin water suction, so as to improve noodles ductility, viscous Resultant force and plasticity.
Tabletting: carrying out tabletting for the dough after curing, it is noted that the roller spacing of double roller, passes through and adjust roll gap when tabletting Tabletting repeatedly, the adjusting of each pressure roller with roll that prolong number identical.The features such as not easily molded due to buck wheat protein, when tabletting, should not press It is excessively thin, it is all 1.4mm that this, which tests all dough sheets,.
Embodiment 1
Stress level: 100,200,300,400,500MPa handle Buckwheat flour 15min, then pressure surface respectively, Buckwheat flour Ratio 30% is added with long patent flour quality, salt adding amount 1.5%, amount of water 35%, the noodle prepared from buckwheat of production obtains 1 different pressures of table Influence to noodles sensory scores.
Dwell time: 300MPa handles Buckwheat flour 10,15,20,25,30min, then pressure surface, and Buckwheat flour adds ratio Be long patent flour be 30%, salt adding amount 1.5%, amount of water 35%.Obtain influence of the 2 different disposal time of table to noodles sense organ.
Wheat flour and Buckwheat flour ratio: taking ultra high pressure treatment temperature is that room temperature 300MPa handles Buckwheat flour 15min, so It is 20%, 25%, 30%, 35%, 40% that the addition of pressure surface afterwards, Buckwheat flour and long patent flour quality, which is compared, adds salt 1.5%, adds water Amount is 35%, obtains influence of the different proportion to noodles shared by 3 Buckwheat flour of table.
As shown in Figure 1, when pressure is 400MPa, strip-breaking rate is decreased obviously, and reaches minimum and significantly lower than other groups; Less, when 500MPa, becomes larger suddenly, and significantly greater than other levels for water absorption rate variation when 100MPa to 400MPa;With pressure Increase, noodles boil loss rate and first reduce increases whole fluctuation less afterwards, illustrates that pressure boils loss rate influence less to noodles.It is in pressure Noodles boil loss rate minimum when 300MPa.
Influence of 1 different pressures of table to noodles sensory scores
As shown in Table 1, pressure is larger to noodles qualitative effects, and sensory evaluation scores are rear after first increasing to be reduced, when pressure is 400MPa Noodles sensory scores' highest is 92.1 points, and it is soft or hard it is suitable, elasticity is good, clean taste does not stick tooth, quality is apparently higher than Other groups.
On the whole, superelevation pressing noodles cooking property increasing in the trend increased afterwards is first reduced with pressure, sense organ is commented Dividing is in first increases and then decreases trend, and ultra high pressure treatment optimum pressure power range is 300-500MPa.
As shown in Figure 2, the ripe strip-breaking rate of noodles with processing the time the ripe broken strip of increase take the lead in reduce after increase, arrived 10 Change when 20min less, in 15min, ripe strip-breaking rate is minimum;The water absorption rate of noodles is with the increase amplitude of variation for handling the time It is very big, integrally first reduce after increasing reduction not only afterwards but also increase, two minimum values, respectively 15min and 25min occurs;Noodles Boil loss rate as time increases, present first reduce after steadily increasing trend, there is minimum value in 15min.
The 2 different disposal time of table is to noodles sensory scores:
In 10 ~ 30min range as the sensory scores of the steady noodles of increase of processing time increase (see Table 2).In conjunction with ripe broken strip Rate, water absorption rate, from the point of view of boiling loss rate, cooking quality is best when 15min, but when 15min the color of noodles whiten, elastic poor, table Surface state is not fine and smooth enough, and transparent texture is unobvious, and sensory evaluation scores are poor.May be due to the HIGH PRESSURE TREATMENT time it is longer to starch, Protein-modified overaction.Therefore show that most suitable processing time range is 15-25min.
As shown in Figure 4, as the adding proportion of Buckwheat flour is between 20% to 30%, ripe strip-breaking rate variation is little, in buckwheat When wheat flour additive amount is 35%, ripe strip-breaking rate is obviously reduced, and reaches minimum and is significantly less than other groups.When additive amount is 40%, Ripe strip-breaking rate improves suddenly, and significantly greater than other groups, illustrates the different ripe strip-breaking rates to noodles of Buckwheat flour adding proportion It is affected;And the water absorption rate of noodles, with the increase of Buckwheat flour adding proportion, water absorption rate is integrally in first to reduce to increase afterwards Trend, water absorption rate change less between additive amount 25% to 30%, have reached minimum value at 35%;Noodles boil loss rate with The variation overall variation of time is bigger, and overall trend is risen overally as the adding proportion of Buckwheat flour increases.
As can be seen from Table 3, the sensory evaluation scores of noodle prepared from buckwheat increase first to increase and reduce afterwards with whole Buckwheat flour addition Billy, add Add ratio at 35%, highest scoring 92.5 is divided, and the bright color of noodles, surface exquisiteness, mouthfeel are tasty and refreshing at this time does not stick tooth, has bullet Property, noodle quality is preferable.
Table 3 processes different proportion shared by Buckwheat flour to noodles sensory scores:
It is above-mentioned to influence that difference is little, and noodles are each when additive amount reaches 40% when showing additive amount 20-35% on the integrated quality of noodles Quality characteristic sharply declines, and illustrates that Buckwheat flour addition should be lower than 40%, but consider that this test is buckwheat various grains noodle, is protecting Add Buckwheat flour as far as possible in the case where card noodle quality, determines that most suitable Buckwheat flour adding proportion is 30-40%.
Embodiment 2
On that basis of example 1, using L9(34) orthogonal test analysis coarse cereals noodle prepared from buckwheat production optimal processing parameter.Test Factor level table is as shown in table 4.
4 experimental factor water-glass of table:
As shown in table 5, different disposal combines the ripe strip-breaking rates of lower noodles, water absorption rate, boils loss rate sensory evaluation scores and have an impact, and feels Official's quality is that consumer judges most directly therefore being here standard according to sensory evaluation scores, divide with most important foundation for noodles superiority and inferiority The effect size of three factors is analysed.As seen from Table 5, the primary and secondary sequence of factor is A > B > C, i.e. stress level > handles time > Buckwheat flour adds ratio;Optimal combination is A2B2C2, but highest group of orthogonal test comprehensive score is combined into A2B2C3, for verifying Optimal result is tested using this two groups of conditions, obtains A2B2C2Sense organ comprehensive score be 90 points be greater than combination A2B2C3, i.e., Ultra high pressure treatment pressure 400MPa, ultra high pressure treatment time 20min, buckwheat flour adding proportion 35%.
5 orthogonal test scheme of table and result:
As shown in table 5, different disposal combines the ripe strip-breaking rates of lower noodles, water absorption rate, boils loss rate sensory evaluation scores and have an impact, and feels Official's quality is that consumer judges most directly therefore being here standard according to sensory evaluation scores, divide with most important foundation for noodles superiority and inferiority The effect size of three factors is analysed.As seen from Table 6, the primary and secondary sequence of factor is A > B > C, i.e. stress level > handles time > Buckwheat flour adds ratio;Optimal combination is A2B2C2, but highest group of orthogonal test comprehensive score is combined into A2B2C3, for verifying Optimal result is tested using this two groups of conditions, obtains A2B2C2Sense organ comprehensive score be 90 points be greater than combination A2B2C3, i.e., Ultra high pressure treatment pressure 400MPa, ultra high pressure treatment time 20min, buckwheat flour adding proportion 35%.
The range analysis of 6 noodle prepared from buckwheat orthogonal experiments of table:
Embodiment 3
Adding salinity is 1.5%, amount of water 35%, Buckwheat flour (super-pressure 400MPa processing 20min's and control) with it is general Logical flour quality addition is than being respectively 20%, 25%, 30%, 35%, 40%.
As shown in Figure 4, two kinds of ripe strip-breaking rates of noodles are increased with the increase of the adding proportion of Buckwheat flour, addition Ripe strip-breaking rate is not much different when ratio is 20% and 30%, 35% when the ripe strip-breaking rate of untreated noodle prepared from buckwheat significantly increase, but pass through The ripe strip-breaking rate of the noodles of processing is decreased obviously, and the two difference is with the biggest gap at this time.
As shown in Figure 5, the water absorption rate of two kinds of noodles all increases with the increase of adding proportion at 25% to 40%, and locates The noodles water absorption rate managed is significantly lower than untreated noodles.
It will be appreciated from fig. 6 that the loss rate of boiling of two groups of noodles all significantly improves with the increase of Buckwheat flour adding proportion, 20% to When 25% and 35% to 40%, noodles made by untreated Buckwheat flour boil loss rate greater than face made of processed flour Item.
As shown in Figure 7, the sensory evaluation scores of the noodles without ultra high pressure treatment with the rising of Buckwheat flour adding proportion and It reduces, and the sensory evaluation scores through handling noodles are smaller after first increasing with the rising of addition ratio, are 35% appearance in additive amount Maximum value.Gap of the sensory evaluation scores of noodles between 25% to 35% is gradually increased, and the noodle quality through ultra high pressure treatment is obvious Higher than untreated noodle prepared from buckwheat.By comparison, noodles made of Buckwheat flour are crossed than unprocessed buckwheat flour through ultra high pressure treatment The integrated quality of noodles made of powder will be got well.
