The evaluation method of the hardness of acidified milk
Embodiment 1
By Fig. 1 and Fig. 2, the evaluation method of the hardness of the acidified milk to embodiment of the present invention 1 describes.Fig. 1 is the figure that represents the evaluation method step of the hardness of the acidified milk of present embodiment.Fig. 2 A～Fig. 2 D is the figure of the evaluation method of the hardness of the acidified milk for present embodiment is described, Fig. 2 A～Fig. 2 C is stereogram, and Fig. 2 D is the profile along A-A ' line in Fig. 2 C.
The evaluation method of the hardness of the acidified milk of present embodiment comprises following operation: prepare acidified milk 1, described acidified milk 1 is contained in the container 2 that top has peristome 2a (step S1); Put into counterweight 3 from peristome 2a, and on acidified milk 1, place counterweight 3 (step S2); Measure from placing counterweight 3 after the stipulated time, counterweight 3 is absorbed in the depth d (step S3) in acidified milk 1; The conversion table of the depth d being absorbed in reference to counterweight 3 and the hardness associated with counterweight 3 is evaluated the hardness (step S4) of acidified milk 1.
First, prepare the acidified milk 1 (step S1) as hardness evaluation object.Acidified milk 1 is that the milk fermentation of animal is solidified and formed.Particularly, acidified milk 1 is for example Yoghourt or cheese.Compared with the acidified milk (soft type or beverage type Yoghourt) of primary fermentation type, the evaluation method of the hardness of the acidified milk of present embodiment can be used on the acidified milk (solid type Yoghourt) in after fermentation type more aptly.If acidified milk 1 is for example Yoghourt, raw mixture is filled in container 2, and prepares fermentate in container 2.
The container 2 that holds acidified milk 1 has peristome 2a on the top that holds acidified milk 1.Thereby at least a portion opening of container 2 can from peristome 2a put into counterweight 3 and make counterweight 3 be placed in acidified milk 1 above.Even if the sealed acidified milk 1 that holds of container 2 gives opening in this operation.The material of container 2 and shape, be not particularly limited.Container 2 is for example the cup-shaped receptacle being formed by plastics or paper.
Acidified milk 1 preferably has smooth upper surface., the whole face of upper surface can be also uneven.For example, can be protuberance or depression with the junction of the inwall of container 2.
Then, put into counterweight 3 from peristome 2a, and by counterweight 3 be placed on acidified milk 1 above (with reference to step S2, Fig. 2 A and Fig. 2 B).The weight of counterweight 3 is corresponding with the hardness of acidified milk 1, predetermines.,, in the time of the hardness of the acidified milk 1 of evaluation comparison softness, use low weight counterweight 3.In the time of the hardness of the hard acidified milk 1 of evaluation comparison, use heavier counterweight 3.
Counterweight 3 is for example cylinder or quadrangular.The preferred rib of counterweight 3 portion becomes chamfering, so that be not applied in the stress of locality.The preferred large object of density to a certain extent of counterweight 3, for example, can use metal object.
The preferred bottom surface of counterweight 3 is smooth.The size of counterweight 3 should be the size that can put into from the peristome 2a of container 2.On the one hand, the base area of counterweight 3 is preferably wide as far as possible.Therefore, counterweight 3 is preferably slightly less than the peristome 2a of container 2.Comparatively preferably, the base area of counterweight 3 equates with the acidified milk 1 that will place counterweight 3 area above.
The face of placing the acidified milk 1 of counterweight 3 is preferably smooth.And counterweight 3 is preferably slowly placed.
Counterweight 3 is absorbed in the inside of acidified milk 1 by deadweight.If the hardness of acidified milk 1 is little, counterweight 3 is absorbed in to compared with depths.On the contrary, if the hardness of acidified milk 1 is large, counterweight 3 is absorbed in more shallowly or is not absorbed in completely.
And, to measure from placing counterweight 3 after the stipulated time, counterweight 3 is absorbed in the depth d (with reference to step S3, Fig. 2 C and Fig. 2 D) in acidified milk 1.The depth d that the distance above and between the bottom surface of counterweight 3 of acidified milk 1 can be absorbed in as counterweight 3 for example as shown in Figure 2 D.At this, the stipulated time refers to, for example 1 second～5 minute, and preferably 3 second～4 minute, comparatively preferably 5 second～3 minute, are more preferably 7 second～1 minute, particularly preferably 10 second～30 seconds.
The conversion table of the depth d then, being absorbed in reference to counterweight 3 and the hardness associated with counterweight 3 is evaluated the hardness (step S4) of acidified milk 1.The conversion table of hardness is to use counterweight 3 to make in advance for the acidified milk with various hardness.
At this, the preparation method of hardness conversion table is described.First, prepare to have multiple acidified milks of various hardness.The hardness use curdmeter of these acidified milks etc. is measured quantitatively.These acidified milks are contained in the container identical with acidified milk 12.Then, S2 is identical with step, places counterweight 3 at these above acidified milk.Then, S3 is identical with step, and mensuration is from placing counterweight 3 after the stipulated time, and counterweight 3 is absorbed in the degree of depth of this acidified milk.Then, record its measured value.
Fig. 3 is the example of hardness conversion table.For the acidified milk of 5 kinds of hardness with h (1)～h (5), record depth d (1)～d (5) that counterweight 3 is absorbed in.And, h (1) < h (2) < h (3) < h (4) < h (5).Now, become d (1) > d (2) > d (3) > d (4) > d (5).
With reference to hardness conversion table, the hardness evaluation method of acidified milk 1 is described.The depth d that counterweight 3 is absorbed in compares with depth d (the 1)～d (5) being recorded on reference table.For example,, if depth d ≈ d (1) can be evaluated as the hardness h of acidified milk h ≈ h (1).Same, if depth d ≈ d (2) can be evaluated as h ≈ h (2); If depth d ≈ d (3) can be evaluated as h ≈ h (3); If depth d ≈ d (4) can be evaluated as h ≈ h (4); If depth d ≈ d (5) can be evaluated as h ≈ h (5).
And, if d (1) > d > d (2) can be evaluated as h (1) < h < h (2).Same, if d (2) > d > d (3) can be evaluated as h (2) < h < h (3); If d (3) > d > d (4) can be evaluated as h (3) < h < h (4); If d (4) > d > d (5) can be evaluated as h (4) < h < h (5).And, if d > d (1), h < h (1).If d (5) is > d, h (5) < h.
Also can obtain in more detail hardness by insertion or matching.
Fig. 3 illustrated the situation of 5 kinds of hardness of conversion table record.But the kind of the hardness of conversion table record is arbitrarily.The kind of the hardness that conversion table records is more, can evaluate in more detail the hardness of acidified milk 1.And the scope of the hardness that conversion table records is wider, can evaluate the more hardness of wide region.
Above, the evaluation method of the hardness of the acidified milk to embodiment of the present invention 1 is illustrated.According to the evaluation method of the hardness of the acidified milk of present embodiment, as long as the corresponding relation between hardness and the counterweight of investigation one time fermentation breast can, by using identical counterweight, be evaluated rapidly and easily the hardness of acidified milk.
Embodiment 2
Fig. 4 is the figure that represents the evaluation method step of the hardness of the acidified milk of embodiment of the present invention 2.The evaluation method of the hardness of the acidified milk of present embodiment comprises following operation: prepare acidified milk, described acidified milk is contained in the container that top has peristome (step S1); Put into counterweight from peristome, and by counterweight be placed on acidified milk above (step S2); Mensuration is from placing counterweight after the stipulated time, and counterweight is absorbed in the depth d (step S3) in acidified milk; The comparison operation (step S4) that the degree of depth that counterweight is absorbed in compares with a reference value associated with counterweight; Evaluated the hardness (step S5) of acidified milk by the threshold value of the result of operation relatively and the hardness associated with counterweight.
First, implementation step S1～S3.Step S1～S3 is identical with embodiment 1.
Then the depth d, counterweight being absorbed in compares (step S4) with a reference value associated with counterweight.The a reference value associated with counterweight is for example the length of its counterweight mid-height.Now, if the depth d that counterweight is absorbed in is the over half of its counterweight height, is judged as and reaches a reference value.On the one hand, if the depth d that counterweight is absorbed in is less than the half of its counterweight height, is judged as and does not reach a reference value.Or, on the contrary, also can be judged as: if the depth d that counterweight is absorbed in is the over half of its counterweight height, do not reach a reference value, if the degree of depth that counterweight is absorbed in is less than the half of the height of its counterweight, reach a reference value.
Then, evaluated the hardness (step S5) of acidified milk 1 by the threshold value of the result of operation relatively and the hardness associated with counterweight.,, if depth d is more than a reference value, the hardness of acidified milk 1 can be evaluated as and be less than certain certain hardness.If depth d is less than a reference value, the hardness of acidified milk can be evaluated as and be greater than certain certain hardness.
More specifically, preferably investigate in advance in the following manner the relation between hardness and the counterweight of acidified milk.First, prepare to have multiple acidified milks of various hardness.Use curdmeter etc. is measured the hardness of these acidified milks quantitatively.Then, investigation counterweight is placed on hardness h1 acidified milk above time, after the stipulated time, making the degree of depth being absorbed in is the threshold value h1 of hardness more than a reference value, and place it in hardness h2 acidified milk above time, after the stipulated time, make the degree of depth being absorbed in be less than the threshold value h2 of the hardness of a reference value.
Thus, counterweight 3 is placed in the situation above of acidified milk 1 of hardness the unknown, in the time that the depth d being absorbed in is less than a reference value, the hardness of acidified milk 1 can be evaluated as to the threshold value h1 that is at least greater than hardness after the stipulated time.And, when depth d is a reference value when above, the hardness of acidified milk 1 can be evaluated as to the threshold value h2 that is at least less than hardness.
In the present embodiment, only need to judge the magnitude relationship between depth d and a reference value.Therefore, without critically measuring depth d.The mensuration of depth d is with visual.But also can measure with determining instrument, sensor or camera etc.
Above, the evaluation method of the hardness of the acidified milk to embodiment of the present invention 2 is illustrated.According to the evaluation method of the hardness of the acidified milk of present embodiment, can judge as the hardness of the acidified milk of evaluation object and be less than certain certain degree of hardness or be greater than certain certain degree of hardness.
Embodiment 3
Fig. 5 is the figure that represents the evaluation method step of the hardness of the acidified milk of embodiment of the present invention 3.The evaluation method of the hardness of the acidified milk of present embodiment comprises following operation: prepare acidified milk, described acidified milk is contained in the container that top has peristome (step S1); Put into counterweight from peristome, and on acidified milk, place counterweight 1 (step S2); Mensuration is from placing counterweight after the stipulated time, and counterweight 1 is absorbed in the depth d 1 (step S3) in acidified milk; Depth d 1 is compared to (step S4) with a reference value associated with counterweight 1; Take out counterweight 1 from peristome, then put into counterweight 2 from peristome, and by counterweight 2 be placed on acidified milk above (step S2-1); Mensuration is from placing counterweight 2 after the stipulated time, and counterweight 2 is absorbed in the depth d 2 (step S3-1) in acidified milk; Depth d 2 is compared to (step S4-1) with a reference value associated with counterweight 2; Evaluated the hardness (step S5) of acidified milk by the threshold value of the result of step S4, step S4-1 and the hardness associated with counterweight 1,2.
Present embodiment is used two kinds of counterweights (counterweight 1,2).Identical with embodiment 2, the relation between preferred hardness and the counterweight of investigating in advance acidified milk.
; when investigation is placed on above the acidified milk of hardness h1 by counterweight 1; after the stipulated time, making the degree of depth being absorbed in is the threshold value h1 of hardness more than a reference value; and while placing it in above the acidified milk of hardness h2, after the stipulated time, make the degree of depth being absorbed in be less than the threshold value h2 of the hardness of a reference value.The value of h1 and h2 is preferably approaching as far as possible.
Hence one can see that, counterweight 1 is placed in the situation above the acidified milk of hardness the unknown, and in the time that the degree of depth being absorbed in after the stipulated time is less than a reference value, the hardness of this acidified milk is at least greater than threshold value h1.And when the degree of depth is a reference value when above, the hardness of known this acidified milk is at least less than threshold value h2.
Same, investigation counterweight 2 is placed on hardness h3 acidified milk above time, after the stipulated time, making the degree of depth being absorbed in is the threshold value h3 of hardness more than a reference value, and while placing it in above the acidified milk of hardness h4, after the stipulated time, make the degree of depth being absorbed in be less than the threshold value h4 of the hardness of a reference value.The value of h3 and h4 is preferably approaching as far as possible.
Hence one can see that, counterweight 2 is placed in the situation above of acidified milk of hardness the unknown, and in the time that the degree of depth being absorbed in after the stipulated time is less than a reference value, the hardness of this acidified milk is at least greater than threshold value h3.And when the degree of depth is a reference value when above, the hardness of this acidified milk is at least less than the threshold value h4 of hardness.
In present embodiment, selected counterweight 1,2 is so that h1 < h2 < h3 < h4.For example, as counterweight 2, use the counterweight that is greater than counterweight 1 weight.
Implement the evaluation method of the hardness of the acidified milk of present embodiment based on above prerequisite.
First, implementation step S1～S4.Step S1～S4 is identical with embodiment 1.
In the operation (step S4) that depth d 1 and a reference value are compared, if depth d 1 is more than a reference value, skips steps S2-1～S4-1, enters the operation (step S5) of evaluation hardness.This is because now, the hardness of acidified milk can be evaluated as and be less than threshold value h2.
On the one hand, in step S4, if depth d 1 is less than a reference value, the hardness of known acidified milk is greater than threshold value h1.But now, the magnitude relationship between the hardness of acidified milk and threshold value h3 and h4 is unclear.Therefore, in this case, execution step S2-1 and step afterwards thereof.
Then, take out counterweight 1 from peristome, then put into counterweight 2 from peristome, and by counterweight 2 be placed on acidified milk above (step S2-1).Then, mensuration is from placing counterweight 2 after the stipulated time, and counterweight 2 is absorbed in the depth d 2 (step S3-1) in acidified milk.
Then, depth d 2 a reference value associated with counterweight 2 compared to (step S4-1).If depth d 2 is less than a reference value, the hardness of acidified milk can be evaluated as and be greater than threshold value h3 (step S5).And, if depth d 2 is more than a reference value, the hardness of acidified milk can be evaluated as and be greater than threshold value h1 and be less than threshold value h4 (step S5).
Above, the evaluation method of the hardness of the acidified milk to embodiment of the present invention 3 is illustrated.According to the evaluation method of the hardness of the acidified milk of present embodiment, can it be three scopes (are less than threshold value h2, are greater than threshold value h1 and are less than threshold value h4 or are greater than threshold value h3) using the softness as the acidified milk of evaluation object.
In the present embodiment, the situation of first placing counterweight 1 is illustrated.Like this, for example, preferably first place the counterweight that weight is little.Because if first place the counterweight that weight is large, acidified milk produces plastic deformation, cannot implement subsequent step.
In addition, a reference value associated with counterweight 1 and with the associated a reference value of counterweight 2 also can be identical.
Embodiment 4
