When the method according to AACC, when the bread that utilizes Stable Micro Systems property tester to measure embodiment 1-8 and comparative example 1-8 is placed the hardness of crumbs after 7 days under normal temperature (25 ℃), obtained the result shown in table 1.
The below is that parameter and the standard that product hardness is measured originated
The parameter of Determination of Hardness:
Pattern: use pressure measxurement
Operation: return to beginning
Speed: 1.0mm/s before experiment
Speed of experiment: 1.7mm/s
Return speed: 10.0mm/s
Measuring distance: 40%
Induction force: Auto-5g
Data are got and are counted: 250pps
The source of Determination of Hardness standard: use AACC (74-09) standard method.
In addition, the bread of embodiment 1-8 and comparative example 1-8 is also carried out the bread flavor experiment, after bread baking on the same day is cooling, invited ten normal people of the sense of taste to pass judgment on the local flavor of bread by sensory evaluation.Result of the test also is shown in following table 1.
Table 1
Figure G2009102158432D00111
In table: the intensity of "+" expression bread flavor, number more multilist shows that local flavor is stronger, "-" expression local flavor is flat.
by the result in table 1 as seen, use is according to embodiments of the invention the 1-8 bread of making and the comparative example 1 that does not use modifying agent, the comparative example 2 that does not wherein comprise maltogenic amylase in complex enzyme formulation, in modifying agent, the content of maltogenic amylase exceeds the comparative example 3-5 of 0.3%~0.7% scope, the bread that does not comprise comparative example 6 making of deactivation dry ferment in modifying agent is compared, the bread that has added bread improver of the present invention, the hardness of bread improves after storing a week, and after having added maltogenic amylase and inactive yeast, the hardness of bread is less, this explanation degree of aging is better delayed.In addition, can also confirm, when maltogenic amylase content in modifying agent less than 0.3% the time, the DeGrain that hardness is improved, and when maltogenic amylase content in modifying agent greater than 0.7% the time, the effect of improvement is substantially constant.Therefore, in this case, in modifying agent, the content of maltogenic amylase is preferably in 0.3%~0.7% scope.
By the result of table 1 clearly, add bread improver of the present invention embodiment 1-8 bread with do not add modifying agent, or only add the comparative example 1-9 of several compositions wherein to compare, and prepared bread hardness is less, and this explanation degree of aging is better delayed.This be because, bread improver of the present invention, formulated by a certain percentage by complex enzyme formulation, antioxidant, emulsifying agent, deactivation dry ferment and starch, by the mutual synergy of complex enzyme and yeast, and making the hardness of bread less, degree of aging is better delayed.
In addition, the above results shows, maltogenic amylase and AMS and other enzymes, inactive yeast, emulsifying agent etc. have good synergy, makes bread show good ageing resistace in the storage later stage.
In addition, the bread of embodiment 1-8 and comparative example 1-9 is carried out the bread flavor experiment, after bread baking on the same day is cooling, invited ten normal people of the sense of taste to pass judgment on the local flavor of bread by sensory evaluation.Result of the test is as shown in following table 2.
It can also be seen that from table 1, along with the increase of inactive yeast addition, the local flavor of bread is better.In addition, also find not add the local flavor of comparative example 1 of any modifying agent the most flat.
In addition, in order to confirm to add the tensile property of dough after bread improver of the present invention, carried out following stretching experiment.
The pertinent instruments that stretching experiment uses is as follows:
Farinograph: 300 gram kneading-throughs, 225 milliliters of burets
Balance: sensibility reciprocal 0.1 gram.
Lucite (plastics) scraping blade
Conical flask: 250ml
The cleaning gauze
The operating environment room temperature requires at 30 ℃.
Before test, open constant water bath box switch and the recirculated water switch of farinograph (300 gram kneading-through), extension meter, set water temperature is 30 degree.Attention will just can be tested after 30 minutes at least, is warming up to 30 ± 0.2 ℃ to guarantee the awake face case of farinograph kneading-through and tensilometer.
The dough fixture is positioned in proofing box, puts a small amount of water in the pallet groove.At least constant temperature could the device dough after 15 minutes at proofing box in the dough harness.
The preparation dough
At first, according to the moisture of the wheat flour of measuring, taking quality, to be equivalent to the 300g water content be 14% sample, and sample is poured in farinograph 300g kneading-through, closes the lid.Then, taking 6 ± 0.1g sodium chloride pours in conical flask, and (actual amount of water approximately lacks 2% water than the wheat flour water absorption that records according to the water yield that adds with the estimation of the wheat flour water absorption of farinogragh testing, to compensate for the impact of sodium chloride, as be soft wheat, must reduce and more add the water yield), then inject from buret the water yield of estimating and dissolve sodium chloride in conical flask.The total Water that adds must make during following (7.2.3) measure, and dough rubs up the dough consistency that can obtain 500 ± 20FU after 5 minutes (curve peak center line value), otherwise must change amount of water, again prepares dough.
Subsequently, start the farinograph device of kneading dough, open covering after rubbing up 0.5-1 minute, with funnel, the sodium chloride solution in conical flask is added in wheat flour from kneading-through lid center immediately, then add a little distilled water with buret from kneading-through right front angle, close the lid.Sodium chloride and distilled water must add in 25s.Scrape into dough (not shutting down) with broken the piece that scraping blade will be bonded on the kneading-through inwall.Rub up 5 ± 0.1min.At this moment the dough consistency value must be between 480~520FU.
The dough that rubs up is taken out (not kneading) from kneading-through, with scissors, dough is cut apart two, make every heavy 150 ± 0.5g.A dough that weighs up is placed on rubbing of tensilometer to be kneaded in the ball device and spherically (if the sticking hand of dough takes out above-mentioned spherical dough, to put into condenser and be twisted into bar.Open the face case of waking up, take out a cover dough harness, the dough that will rub rapidly bar with the hands is clamped in fixture and (is coated with in advance a little mineral oil).Another part dough is kneaded into ball equally, is twisted into bar, and folder advances fixture.Two parts of fixtures push together with pallet the face case of waking up, and shut chamber door, the beginning timing, and face interval 45min wakes up.After each face of waking up is complete, begin to make stress strain curve.
Stress strain curve as depicted in figs. 1 and 2, each index of the stress strain curve in Fig. 1 and Fig. 2 is described as follows:
Tensile energy: refer to the area that stress strain curve surrounds, unit is [square centimeter]
Ductility: refer to that touching dough from the hand-pulled noodles clasp joint begins to be broken to dough, the distance of stress strain curve abscissa, unit is [mm].
Enhanced stretch resistance: referring to stretch, to begin to ductility be the EU value at 50mm place.
Maximum tension resistance: refer to maximum EU value in stress strain curve.
Draw ratio: enhanced stretch resistance and ductility ratio.
Maximal draw ratio: maximum tension resistance and ductility ratio.
Fig. 1 shows the formula of embodiments of the invention 1 to the stress strain curve result of dough draftability.Fig. 2 shows the formula of comparative example 1 of the present invention to the stress strain curve result of dough draftability.In Fig. 1 and Fig. 2, curve 1, the 2 expressions extension test result of 45 minutes, curve 3, the 4 expressions extension test result of 90 minutes, and curve 5,6 represents the extension test result of 135 minutes.
Can find out from the result of Fig. 1 and Fig. 2, use has better improvement effect according to the ductility of the dough of modifying agent of the present invention, and especially in the time of 45 minutes, the ductility of embodiment 1 is higher more than 30% than comparative example 1.
In addition, show together the ductility of the dough of embodiment 1-8 and comparative example 1-6 in following table 2.
