Rear viscosity is 60cP to room temperature for a period of time, and product viscosity fluctuates not during placement 9 months at normal temperature Greatly, phenomena such as being also precipitated without layering and whey.
Comparative example 1
With embodiment 1, be only selected soybean polyoses molecular weight be 25000~1000000Da, the other the same as in Example 1.
Comparative example 2
It is only the low-ester pectin removed in raw material, while high-ester pectin additive amount is adjusted to 0.4% with embodiment 2, remaining With embodiment 2.
Comparative example 3
It is only that low-ester pectin additive amount is 0.2% in adjustment raw material, high-ester pectin 0.2%, remaining is same with embodiment 2 Embodiment 2.
Comparative example 4
It is only that high acyl gellan gum additive amount is adjusted to 0.4%, while low acyl gellan gum additive amount in raw material with embodiment 3 It is adjusted to 0.05%, remaining is the same as embodiment 3.
Comparative example 5
It is only homogenization pressure in step S2 with embodiment 4, firsts and seconds pressure is respectively 150bar and 50bar.
Effect example 1
Finished yogurt prod carries out heat preservation test, i.e., 25 DEG C and 37 DEG C are respectively placed 1 month, opens 3 sample packets of packet every time, observes Yoghourt State.The state of Yoghourt is cut off respectively from bottom and top, has seen whether whey precipitation phenomenon, and it is viscous to measure upper and lower layer Degree (measuring temperature is 25 DEG C).
37 DEG C of heat preservation 1 month test result such as the following table 6:
Table 6
By upper table result it is found that 25 DEG C place 1 month after, it is existing without bleed no matter embodiment product upper layer or lower layer As, and upper and lower level viscosity difference is smaller.There is obvious bleed on comparative example 1~4, upper layer, although 5 upper layer of comparative example is without obvious cream Clearly, but compare with initial sample, upper and lower level differences in viscosity increases;Same trend is presented with 25 DEG C of products in 37 DEG C of heat preservation results.
Effect example 2
Subjective appreciation method
Select 10 dairy products researchers for having a background context to carry out sense organ training and select at random 5 names therein as Subjective appreciation person.Standards of grading are as shown in table 7 below:
7 subjective appreciation standard of table
It counts the score data of sensory evaluation person and is averaged, indices score, which is added, calculates total score, and score is higher Representative products quality is better, and measurement result see the table below 8:
Table 8
Product number Embodiment 1 Embodiment 2 Embodiment 3 Embodiment 4 Comparative example 5
Flavor 23 22 23 22 22
Whey 21 21 22 23 12
Quality 23 21 20 21 9
Color 23 22 23 19 18
Total score 90 86 88 85 61
It can be seen from the above result that embodiment 1,2,3 and 4 has preferable flavor and quality;Comparative example 5 has a little particle, Quality is coarse, smoothness is poor.
Specific embodiment in the present invention is only explanation of the invention, is not limitation of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in scope of the presently claimed invention.
