Parameter such as the following table 7 of 4.1 extruding-puffing techniques adjustment front and back.
More than the 7 cereal foods manufacturing parameters of table
The product specific volume that 4.2 extruding-puffing techniques adjustment front and back obtains is as a result, such as the following table 8.
8 product specific volume apparent parameter of table
Note: data are that different time samples product average value.
From upper table 8 it is found that density of the product specific volume data before and after process optimization is substantially reduced, apparent size shows extruding Small product size increases after circle optimization, these show the puffed degree increase of product after process optimization, and bubble becomes larger in structure, mouthfeel It is more crisp.
The products'texture analysis result that 4.3 extruding-puffing techniques adjustment front and back obtains
For the more scientific crisp degree of judgement product, project has carried out texture analysis and has checked, Food Texture detection mode There are compression, puncture etc., in conjunction with more bread basket characteristics.
The present embodiment, with more comprehensive evaluation products'texture, is judged crisp using puncturing and compressing two ways progress Characteristic.
4.3.1 experiment is punctured
Puncturing experimental method is to set certain puncture ratio with thin cylindrical body probe puncture sample, and record at the uniform velocity punctures through Stress condition in journey, is analyzed through data, judges products'texture characteristic, analyzes crispiness.It is same that the present embodiment punctures texture analysis When have chosen two mainstream product of market and compare, test result see the table below 9 and attached drawing 8.(a) is shown excellent in Fig. 8 Change before product, (b) be shown process optimization after product, (c) be shown the crisp paddy of nest happy (d) be shown family Le Shi it is crisp The texture curve of circle circle product.
Table more than 9 cereal foods optimizations front and back and part similar product texture data result
It is found by the products'texture interpretation of result of table 9 and Fig. 8, the crisp degree of more cereal foods after optimization is promoted bright It is aobvious, and and commercial like product gap in texture it is unobvious.It is to be noted that more cereal foods of the application be Under the conditions of seitan class content is higher, the crisp degree of product remains to preferable level identical with market similar-type products, illustrates that this is excellent Technological parameter is good after change, is suitble to the extrusion of more more cereal foods of seitan class, and the optimization technique research and development meaning is very big.
4.3.2 compression experiment
Compression texture analysis experiment is to squeeze sample with larger cross-section cylinder or disk probe, records sample extrusion The process of rupture is more scientific analysis, and project experiment carries out single sample extruding with cylindrical probe and disk probe carries out multiplicity Product squeeze two methods and are analyzed, and judge products'texture characteristic, determine crispiness.As a result 10 and attached drawing 9-12 be see the table below.
The main physical index table of 10 sample of table.
From upper table and Fig. 9-12 as it can be seen that in extrusion process, sample stress can rupture, and persistently break in extrusion process It splits, therefore many big and small peak values occurs.From the point of view of the maximum, force in extrusion process, the hardness of product is bright after optimization technique It is aobvious to be lower than original process product sample;Identical deformation occurs, the strength minor swing after optimization technique in product extrusion process is very It is more, and original process product then fluctuate it is obvious less, it is seen that product is more more crisp after optimization technique, and original process product is partially hard.
In addition, slope of a curve also reflects the difference of the two, product curve relative smooth slope is smaller after optimizing technique, Strength moment increases when original process product squeezes, and slope is larger, can also equally reflect that original process product is harder, produces after optimizing technique Product are more crisp, and hardness is smaller.
In addition, column diagram is made in the main physical index of different samples to compare the difference between two class samples, as a result See attached drawing 13-16.1# sample is more cereal foods after optimization technique in figure, and 2# sample is the more cereal foods of original process.
As can be seen from Fig. 13, the indices of 2# sample are below 1# sample, i.e. 1# sample is thicker, and rupture and maximum occurs Hardness needs to squeeze longer displacement.The indices of 1# sample and respectively less than 2# sample as can be seen from Fig. 14, it is seen that 1# sample Hardness is smaller, and crisp brittleness is better than 2# sample, and 2# sample is then relatively partially hard.
From Figure 15 as it can be seen that the indices of 2# sample are below 1# sample, the sample for equally reflecting 1# is thicker, occurs broken It splits and needs to squeeze longer displacement with highest hardness.The indices of 1# sample and respectively less than 2# sample as can be seen from Fig. 16, together It is smaller that sample reflects 1# sample hardness, and crisp brittleness is better than 2# sample, and 2# sample is then relatively partially hard.
To sum up, by each index of above-mentioned test experiments as a result, reflect before and after process optimization well sample hardness, Difference in terms of crisp brittleness.Although from result reflect optimization after more cereal foods thickness it is thicker, hardness is less than normal, crisp brittleness compared with It is good, the more cereal foods thinner thicknesses of original process, but hardness is larger, and crisp brittleness is less than cereal foods more after optimization.
The final product extruding-puffing technique manufacturing parameter determined after optimization are as follows: inlet amount 180.0kg/h, water flow 14.4kg/h, outlet pressure 43.7bar, outlet temperature: 178 DEG C, torque 778Nm, cutter rotating velocity 1107rpm, screw speed 269rpm, power 22kw, specific energy 122.4wh/kg.
The crisp degree of more cereal foods that after the optimization prepared by technique is obviously improved.The experiment mainly passes through increase charging Amount reduces the operation such as certain water, increases material squeeze pressure, improving material temperature, while screw rod being made to have stronger shearing Dynamics, after serial adjusting and optimizing, the crisp equal texture characteristics of final products have clear improvement, and achieve the desired results.
5, more cereal puffing food later period toning seasoning embodiments
