Description
Technical field
The present invention relates to the dairy products field, particularly, relate to a kind of liquid diary product that contains boiled fragrant rice juice and preparation method thereof.
Background technology
Milk is nutritious, digest and assimilate easily, inexpensive, instant, is near perfect food, and person " white blood " is optimal wholefood.Comprise a large amount of protein in the milk, be mainly casein, albumin, globulin etc., 8 seed amino acids of needed by human are arranged in the 20 contained several amino acids, milk proem matter is complete protein, and digestibility is up to 98%, and absorption easy to digest is desirable wholefood.
Scented rice is one of Major Foods of people's daily life, has very high nutritive value, is the basic food of element of supplementing the nutrients, and especially thin rice gruel has tonifying spleen and stomach, clearing lung-heat effect.Mostly the milk beverage that adds in the market cereals is directly to add grain dust, loses in a large number easily the nutritional labeling such as B family vitamin in the cereal, and the inclined to one side stiff of mouthfeel.CN99111321.7 discloses the thin rice gruel milk beverage, wherein during boiling thin rice gruel with rice: water=3.5: 100-5: 100 proportionings, but the experiment proved that its ratio gained thin rice gruel special mouthfeel is light, can not embody the characteristic of Mi Xiang.
Adding fragrant rice juice in the milk can cause the stability of milk to change, the increase of the water yield can cause milk in the long shelf life put procedure bleed to occur, cause protein stability to descend grumeleuse occurs, contain a large number of nutrients of from scented rice, separating out in the fragrant rice juice simultaneously, can increase the unstability of milk systems, so need distinctive prescription to address the above problem.
Summary of the invention
The purpose of this invention is to provide a kind of liquid diary product that contains fragrant rice juice.
A further object of the present invention provides the above-mentioned method that contains the liquid diary product of fragrant rice juice of preparation.

Investigating the result from above stability experiment can find out: utilize the prepared milk beverage of stabilizing agent of the present invention (embodiment 1-4) product structural state after the normal temperature preservation was placed 2 months in 8 months and 37 ℃ even, only have a small amount of fat floating phenomenon and slight precipitation, compare with commercially available similar milk beverage (Comparative Examples 1,2), milk beverage stability of the present invention is better, and shelf life is longer.
The flavored milk flavor taste that contains boiled fragrant rice juice changes test experiments
To the taste tests that the flavored milk that contains boiled fragrant rice juice is carried out, experiment mainly changes for its flavor taste within the shelf-life and carries out.
The test experiments method is: get respectively the product of embodiment of the invention 1-4 as specimen, carry out " getting two in three " with control sample (control sample is the of that month fresh sample of producing) and taste experiment (triangle method of inspection, triangle test), mainly investigate the situation of change of product special flavour in the shelf-life.The sample of every embodiment is done the taste sensory test one time within per month, taste about number 50 people for every group, and the men and women respectively accounts for half, all has certain trial test experience.
During each taste evaluation, every group of sample comprises two specimen and a control sample, or two control samples and a specimen, and the order that sample is put adopts random sequence, and sample appearance is without obvious characteristic difference.If the trial test personnel have correctly selected two identical samples of smell according to growing smell difference from three samples, prove that then there are taste smell difference in specimen and control sample; If select mistake then prove specimen with control sample without taste smell difference.
Taste complete add up tasting the result afterwards, according to " triangle test check table " in the food sense organ appraise method (" appraise of food sense organ " publishing house of South China Science ﹠ Engineering University in February, 2003 second edition) as can be known, surpass more than 24 people if make the people of selecting properly, can think that there are notable difference in two set products taste and mouthfeel on 5% level of signifiance.The product special flavour sensory difference comparing result statistics of each embodiment sees also following table 4:
The shelf life of products intussusception smell of each embodiment of table 4 changes tastes the comparative result statistics
Can learn according to statistics: the embodiment of the invention 1,2,3 product within the shelf-life mouthfeel and the new product in first six months, produced with this month of local flavor on 5% level of signifiance without obvious difference, it is less to prove that product of the present invention flavor taste within the shelf-life changes, within tolerance interval.
