.
Embodiment 1
The present embodiment mainly introduces the interpolation of dietary fiber to dumpling wrapper(Dough cover)Impact, concrete impact situation briefly introduces such as Under.
1st, the impact to the optimal digestion time of dumpling skin for the dietary fiber addition
According to the assay method of the optimal digestion time of dumplingss in specific embodiment, flour adds different proportion, inhomogeneity It is measured after the dietary fiber of type, dietary fiber addition(Mass ratio)And most preferably digestion time measurement result is as follows Shown in table:
.
As can be seen from the above table, different dietary fibers, in the case of Different adding amount dumpling skin optimal digestion time not phase With.With the increase of dietary fiber addition, the optimal digestion time of dumpling skin is on a declining curve.Its reason is mainly:Dumpling skin Optimal digestion time is proportionate with the content of starch in flour, and after adding dietary fiber, in flour, content of starch reduces, most preferably Digestion time shortens, and addition is bigger, and optimal digestion time is shorter.
2nd, the impact to quick-freezing the boiled meat dumpling peel cooking quality for the dietary fiber
According to the assay method of water absorption rate described in specific embodiment and cooking loss rate, to dissimilar dietary fiber, no With dumpling wrapper in the case of addition(Dough cover)Water absorption rate and cooking loss rate situation be measured, measurement result is as shown in Figure 1, Figure 2 Shown.
The water absorption rate of dumpling wrapper and cooking loss rate may determine that the chewy sense of dumpling skin, hardness, elasticity, sliding mouthfeel etc..From Fig. 1 can be seen that the increase with dietary fiber addition, and the water absorption rate of dumpling wrapper increases, and adds soybean fiber dumplingss The water absorption rate of skin is more than the water absorption rate adding rice bran-fiber.The retentiveness of soybean dietary fiber is more than the water holding of rice bran dietary fiber Property, so the dumpling skin water absorption rate that with the addition of soybean dietary fiber is more than the water absorption rate of rice bran dietary fiber.High water absorption rate helps In the output capacity improving product, increase the quality of dumpling wrapper.
Figure it is seen that with the increase of dietary fiber addition, cooking loss rate reduces, but when dietary fiber adds When dosage is more than 3%, cooking loss rate has raised again.And with the addition of the cooking loss rate of the dumpling skin of rice bran-fiber and be less than and add Add soybean fiber.But after being added beyond 3% dietary fiber, dietary fiber absorbs excessive moisture, and water is made with mucedin Consumption and action time have reduced, thus hindering the formation of networked dough structure, the ability of parcel starch granuless reduces, and makes Become the loss of dry, cooking loss rate increases.And the water absorption of soybean fiber is more than rice bran-fiber, so it is fine to add Semen sojae atricolor Dimension cooking loss rate be increased above add rice bran-fiber.
3rd, dumpling wrapper(Dough cover)TPA quality structure Parameter analysis
Using Texture instrument, the quality structure situation in the case of different dietary fibers, Different adding amount is measured, measurement result is as follows Shown in table:
As can be seen from the above table, after adding dietary fiber, the hardness of dumpling wrapper, elasticity, chewiness, restoring force increased, and glue Attached property decreases.And add the dumpling skin of soybean dietary fiber, be all not so good as in terms of elasticity, hardness, chewiness and restoring force plus Enter the dumpling skin of rice bran-fiber.Add a certain amount of dietary fiber has improving effect to the quality of dumpling skin, but adds excessive meals After fiber, there is deterioration in the quality of dumpling skin.The results of analysis of variance shows:After adding rice bran dietary fiber, the adhesiveness of dumpling wrapper, Elasticity, chewiness are in significant difference.When addition is less than 3%, hardness, restoring force difference is not notable, and is increasing the meals in 3% During food fiber, all there were significant differences for hardness, restoring force.Add soybean dietary fiber dumpling skin, addition be less than 1% when hardness, Elasticity, chewiness and restoring force difference is not notable, increases soybean dietary fiber content, in significant difference.
Because dietary fiber has stronger retentiveness, meeting imbibition during dough-making powder, and a part of mucedin Form network, thus being conducive to increasing the quality of dumpling skin.After adding more dietary fiber, the stronger dietary fiber of retention ability is inhaled Receive excessive moisture, competition produced to mucedin water absorption, hinder time of contact and the exposure of water and mucedin, Hinder mucedin fully to absorb water formation network structure, reduce dumpling skin quality.And the water swellability of dietary fiber is relatively Greatly, the abundant extension of gluten may be affected after addition, and dilute mucedin, so that the quality of dumpling skin is reduced.Soybean dietary The water swellability of fiber is more than rice bran dietary fiber, so it is stronger to add soybean dietary fiber that the deterioration of quality is acted on.
4th, dietary fiber boils the impact of rear obdurability to quick-freezing dumpling skin
As shown in Figure 3 to obdurability measurement result in the case of different dietary fibers, Different adding amount.
Boil the boiling fastness that rear obdurability reflects dumpling wrapper to a certain extent, the rear obdurability dough-making powder biceps of boiling of dumplingss has Close.Preferably boil rear obdurability and represent that cracky do not allowed in boiling process by dumplingss.From figure 3, it can be seen that with addition Increase, the rear obdurability that boils of dumpling wrapper has raised, but rice bran dietary fiber addition is more than 3%(Soybean dietary fiber exceedes 1%)Afterwards, obdurability reduces.This demonstrate the dumplingss dumpling skin cracky that with the addition of soybean dietary fiber.
When dietary fiber addition is less, dietary fiber can strengthen the network structure of gluten, is conducive to gluten network to tie The maintenance of structure, makes the obdurability of dough increase.But after adding excessive dietary fiber, hinder the effect of water and mucedin, Dilute mucedin, hinder the formation of gluten network structure so as to obdurability reduces.The water swellability of soybean fiber It is better than rice bran-fiber, so the dumpling skin obdurability adding soybean fiber is less than the dumpling skin adding rice bran-fiber.
5th, the impact of the sensory evaluation to dumpling skin for the dietary fiber addition
According to the sensory evaluation scores standard in specific embodiment, to the dumpling wrapper in the case of different dietary fibers, Different adding amount (Dough cover)Carry out sensory evaluation scores, concrete evaluation result is as shown in the table:
.
As can be seen from the above table, with the increase of addition, the sensory evaluation scores of dumpling skin increase, after addition is more than 3%, The sensory evaluation scores of dumpling skin reduce.The dumpling skin adding rice bran dietary fiber is in terms of apparent, palatability, toughness, slickness and food flavor It is superior to soybean dietary fiber, especially in terms of food flavor, the dumpling wrapper that with the addition of rice bran dietary fiber clearly enhances dumpling skin Wheat fragrance.Wherein the sensory evaluation scores of toughness viscosity are consistent with the measurement of above-mentioned dumpling cortex structure.But after interpolation rice bran-fiber, water The color and luster of dumpling skin and viscosity decrease.
For the research of the dumpling wrapper containing dietary fiber, not only to consider its nutritive value and health care, also will note Its impact to quality of weight.
Comprehensive above test, add the impact to dumpling skin quality of the dumpling skin of rice bran dietary fiber be better than adding soybean dietary fine The dumpling skin of dimension, and with the addition of the dumpling skin of soybean dietary fiber damaging problem easily occurs.So using rice bran dietary fiber as former Material is added to the test effect in dumpling wrapper with optimum.
6th, rice bran-fiber is to dumpling wrapper(Dough cover)The impact of microstructure
To dumpling wrapper in the case of different content rice bran-fiber(Dough cover)It is scanned electron microscopic observation, be wherein not added with rice bran-fiber Dumpling wrapper microstructure such as Fig. 4(Left side is × 1000, and right side is × 2000)It is shown,
Add 1%(Mass ratio)Dumpling wrapper microstructure such as Fig. 5 of rice bran-fiber(Left side is × 1000, and right side is × 2000) It is shown,
Add 3%(Mass ratio)Dumpling wrapper microstructure such as Fig. 6 of rice bran-fiber(Left side is × 1000, and right side is × 2000) It is shown,
Add 5%(Mass ratio)Dumpling wrapper microstructure such as Fig. 7 of rice bran-fiber(Left side is × 1000, and right side is × 2000) It is shown,
Add 7%(Mass ratio)Dumpling wrapper microstructure such as Fig. 8 of rice bran-fiber(Left side is × 1000, and right side is × 2000) It is shown,
Add 9%(Mass ratio)Dumpling wrapper microstructure such as Fig. 9 of rice bran-fiber(Left side is × 1000, and right side is × 2000) Shown.
By the microstructure of scanning electron microscopic observation dough, similar to a continuous substrate, mucedin is in net to dough Network structure, starch is wrapped in the netted film of mucedin.From Fig. 4 ~ 9 as can be seen that Different adding amount dumpling skin micro- See structure to have differences.Blank dumpling skin(Fig. 4)Gluten network structure ratio more loose, lack of homogeneity, between gluten network exist Space more.Fig. 5 shows, after with the addition of 1% dietary fiber, the space between gluten network has been reduced, but dumpling epidermis face Uniformity is also poor.Fig. 6 shows, the space that with the addition of between the dumpling skin gluten network of rice bran dietary fiber is few, and network compares Uniformly, structure is dense.Fig. 7 can be seen that dietary fiber and protein has initially formed irregular substrate, exposed shallow lake Powder increases.In Fig. 8 and 9, exposed starch granuless substantially increase, and the network structure of protein is diluted.
In sum, when addition is less than 3%, rice bran dietary fiber has improvement result to the structure of dumpling skin.Work as addition During for 3%, the network structure ratio of gluten is more uniform, fine and close, and the space between network is few, this with test this addition quality before Preferably match.And after addition is more than 3%, exposed starch increases, network structure is gradually diluted, and structure is deteriorated.
Embodiment 2
The present embodiment mainly introduces the impact added to stuffing material of dietary fiber, and every 100 parts of stuffing material are configured to:3 parts of Vegetable oil lipoproteines, 60 portions of meats(Carnis caprae seu ovis), 30 portions of vegetable (Brassica rapa L), 2 portions of salt, 5 portions of soy sauce.
1st, dietary fiber Different adding amount is to stuffing material organoleptic effects
According to the evaluation criterion of stuffing material in specific embodiment, to dietary fiber(Rice bran-fiber)In the case of Different adding amount Organoleptic effects are evaluated(Carnis caprae seu ovis lean to fat ratio is 1:1), concrete evaluation result is as shown in Figure 10 and following table:
As seen from Figure 10, add in dumpling filling 0.5% mass ratio dietary fiber when, the organoleptic quality of quick-freezing boiled dumplings reaches Best.Add a certain amount of dietary fiber in dumpling filling, mouthfeel is more smooth, and the conglobation property of filling for dumplings is relatively good, contributes to changing The greasy feeling of kind quick-freezing boiled dumplings, and increased obdurability and the hardness of dumpling filling;Because dietary fiber has retentiveness, also increase The moisture of dumpling filling, makes quick-freezing boiled dumplings decoction increase.But after addition is more than 0.5% dietary fiber, slightly slag sense, and And obdurability reduces.
2nd, the impact evaluation to organoleptic quality for the lean to fat ratio in stuffing material
Because lean to fat ratio different in stuffing material are larger for organoleptic effects, thus in above-mentioned optimal 0.5% dietary fiber addition In the case of, organoleptic effects situation is evaluated in the case of meat difference lean to fat ratio in stuffing material, concrete evaluation result is as schemed 11 and following table shown in:
As seen from Figure 11, lean to fat ratio be 1:When 1, organoleptic quality is best.Add excessive lean meat in dumpling filling, dumpling filling Dense structure, but mouthfeel is harder, aroma fades;Add excessive fat meat although comparison is fragrant, but excessively greasy, and also hardness is bright Aobvious reduction, is difficult agglomerating.After adding certain dietary fiber, suitably increase the amount of fat meat, so that quick-freezing boiled dumplings fragrance is increased, and Fragrant and oiliness, and also decrease with respect to traditional quick-freezing boiled dumplings cost.
Embodiment 3
On the basis of above-described embodiment 1, embodiment 2, can obtain as drawn a conclusion:Dumpling wrapper(Dough cover)Middle dietary fiber optimal Addition is 3%;In stuffing material, the optimum addition of dietary fiber is 0.5%, and now optimal lean to fat ratio is 1:1.On this basis, right Optimal quick-freezing boiled dumplings production technology has carried out further discussion, is briefly discussed below.
In above-described embodiment 1,2 and the present embodiment, flour used is the dumpling special flour of certain brand, and previous experiments show, The optimal amount of water of this flour is 43%, and because dietary fiber has very strong retentiveness, thus after adding dietary fiber, The optimal amount of water of flour can change.
With amount of water in above-mentioned flour(Dough-making powder amount of water), dumpling wrapper(Dough cover)Meals in middle dietary fiber addition, stuffing material In food fiber addition, stuffing material, lean to fat ratio is influence factor, and inventor has carried out orthogonal experiment, orthogonal test influence factor's level Table setting is as follows:

.
1st, dietary fiber adds the impact to quick-freezing boiled dumplings dumpling Frost cleft rate
Dumpling wrapper in quick-freezing boiled dumplings(Dough cover)In the case of middle difference dietary fiber addition, Frost cleft rate measurement result such as Figure 12 institute Show.
It can be recognized from fig. 12 that when adding the dietary fiber of different proportion in the dumpling wrapper of quick-freezing boiled dumplings, the jelly of dumplingss Split rate different.The Frost cleft rate of quick-freezing boiled dumplings when the addition of dietary fiber is below 5%, can be reduced, but more than 5% after, bursting by freezing Rate rises.With the increase of storage period, the Frost cleft rate of dumpling skin is all increased slightly, and the increase of the Frost cleft rate without dietary fiber Ratio is more than the dumplingss adding dietary fiber.Addition is that the quick-freezing boiled dumplings Frost cleft rate of 3% dietary fiber is minimum, after preserving 90 days, Reduce by 37.88% than matched group.
2nd, dietary fiber adds the impact to quick-freezing boiled dumplings drying loss
Dietary fiber(Rice bran-fiber)In the case of Different adding amount, the impact result to quick-freezing boiled dumplings drying loss is as shown in figure 13.
Drying loss refers to food in freezing process, because steam pressure difference causes the evaporation of food surface moisture, leads to quality Minimizing.Drying loss not only reduces the quality of food, also can reduce local flavor and the nutritive value of food.Can from the result of Figure 13 To find out, after adding dietary fiber in quick-freezing boiled dumplings, drying loss has reduced, and this may be relevant with the high retentiveness of dietary fiber. With the increase of storage time, drying loss all assumes increase trend, adds the quick-freezing boiled dumplings of dietary fiber difference compared with matched group Not notable.
3rd, dietary fiber adds the impact to quick-freezing boiled dumplings cooking quality
Dietary fiber(Rice bran-fiber)In the case of Different adding amount, quick-freezing boiled dumplings water absorption rate and cooking loss rate are affected respectively such as Figure 14, shown in 15.
It is seen from figure 14 that with the increase of dietary fiber addition, water absorption rate increases, and dietary fiber has well Retentiveness, so with the increase of dietary fiber content in dumpling skin, the water absorption rate of dumpling skin increases.With the increase of storage period, inhale Water rate has declined, and the dumplingss water absorption rate without dietary fiber declines than the quick-freezing boiled dumplings water absorption rate adding dietary fiber Many.It can be seen from fig. 15 that with the increase of dietary fiber addition, cooking loss rate reduces, but works as dietary fiber addition During more than 3%, cooking loss rate has raised again;Cooking loss rate with the increase quick-freezing boiled dumplings of storage period increases, without The dumplingss of dietary fiber absorbance after storing 90 days increases by 58.9%, and the quick-freezing boiled dumplings incrementss that with the addition of dietary fiber are equal Less than matched group.
4th, dietary fiber adds the impact to quick-freezing boiled dumplings acid value, peroxide value
Dietary fiber(Rice bran-fiber)In the case of Different adding amount on quick-freezing boiled dumplings acid value and peroxide value impact respectively as Figure 16, Shown in 17.From Figure 16,17 as can be seen that increase with storage period, the acid value of quick-freezing boiled dumplings and peroxide value increased, and Add dietary fiber more, increase fewer.After 90 days, the acid value without the quick-freezing boiled dumplings of dietary fiber increased 55.97%, peroxide value increased 38.89%, and the quick-freezing boiled dumplings acid value adding 0.5% dietary fiber increased 36.38%, peroxide Change value increased 26.67%, adds a certain amount of dietary fiber can delay acid value, peroxide value in quick-freezing boiled dumplings dumpling filling Increase.It is probably that dietary fiber has holding oiliness, after adding dietary fiber, a part of oils and fatss in dumplingss are inhaled by dietary fiber Attached, dietary fiber plays buffer action to oils and fatss, so having delayed the increase of acid value, peroxide value.
5th, the optimal production technology of quick-freezing boiled dumplings
According to above-mentioned orthogonal test designs table, the dumplingss Analyses Methods for Sensory Evaluation Results under the conditions of varying level is as shown in the table:
.
Quick-freezing keeps the key that good organoleptic quality is this experiment, and this experiment is used as evaluation criterion by organoleptic indicator.
As can be known from the above table, optimum proportioning is:Amount of water 45%, lean to fat ratio 1 in flour:1st, dietary fiber addition in stuffing material 0.6%th, dietary fiber addition 3% in dumpling wrapper.Size analysis according to extreme difference understands, to dietary fiber quick-freezing boiled dumplings organoleptic quality Impact size be followed successively by:In dietary fiber addition > dough-making powder amount of water > lean to fat ratio > dumpling filling in dumpling wrapper, dietary fiber adds Dosage.In dumpling wrapper, the impact to Deep-Frozen Dumpling Quality for the dietary fiber addition is maximum, and dietary fiber in lean to fat ratio and stuffing material Addition impact less.
To optimum formula (amount of water 45%, lean to fat ratio 1:1st, dietary fiber addition 0.6% in filling, dietary fiber adds in skin Dosage 3%) carry out confirmatory experiment, product sensory is evaluated and must be divided into 94, and this quick-freezing boiled dumplings chews tasty and refreshing, flexible, damaged few, taste Road is delicious, fragrant and oiliness.
The speed dumplingss of different storage time are detected according to relevant criterion, the following institute of concrete testing result simultaneously Show.
After the completion of quick-freezing boiled dumplings preparation(Complete the same day)Quality measurements are as shown in the table:
.
After preserving 23 days, quick-freezing boiled dumplings quality measurements are as shown in the table:
.
After preserving 1 year, quick-freezing boiled dumplings quality measurements are as shown in the table:
.
