Summary of the invention
The object of this invention is to provide a kind of lactobacillus fruit juice drink and preparation method thereof, the method adds streptococcus acidi lactici fermented solution first in the beverage of high juice content, meanwhile, and the lactobacillus fruit juice drink that preparation method of the present invention obtains, mild acidity, has good color and luster, local flavor and stability.
For achieving the above object, the present invention adopts following technical scheme:
A kind of lactobacillus fruit juice drink, it is characterized in that, comprise the reconstituted milk of 5 ~ 25%, 4 ~ 10% fruit inspissated juices, 2 ~ 13% mango juice, 5 ~ 20% white granulated sugar, 0.01 ~ 0.06% vitamin C, 1 ~ 6% highly enriched zymotic fluid, 0.1 ~ 0.5% acid, the stabilizing agent of 0.1 ~ 0.7%, the acidity regulator of 0.01 ~ 0.05%, surplus is water.
According to mass percent, also comprise the flavoring essence of 0.05 ~ 0.14% and/or the natural colouring matter of 0.02 ~ 0.1%.
Comprise the reconstituted milk of 5 ~ 25%, 4 ~ 10% fruit inspissated juice, 2 ~ 13% mango juice, 10 ~ 20% white granulated sugar, 0.02 ~ 0.04% vitamin C, 1 ~ 6% highly enriched zymotic fluid, 0.1 ~ 0.5% acid, the stabilizing agent of 0.2 ~ 0.4%, the acidity regulator of 0.01 ~ 0.04%, surplus is water.
Described fruit inspissated juice is one or more in AJC, pears inspissated juice, "Hami" melon inspissated juice, pineapple concentrated juice, banana inspissated juice.
In described mango juice, soluble solid content is 15.0 ~ 21.0Brix; Described acid is lactic acid or citric acid.
Described stabilizing agent is one or both in pectin, sodium carboxymethylcellulose.
Described acidity regulator is one or more in sodium acid carbonate, sodium hydrogen phosphate, natrium citricum.
A preparation method for lactobacillus fruit juice drink, comprises the following steps:
1) according to mass percent, white granulated sugar, stabilizing agent, acidity regulator, water, reconstituted milk are mixed, obtains feed liquid A;
2) highly enriched zymotic fluid is mixed with feed liquid A, obtain feed liquid B;
3) acid, vitamin C are mixed with feed liquid B after mixing with water again, obtain feed liquid C;
4) carry out homogeneous operation after mango juice, fruit concentrate, water being mixed with feed liquid C, obtain feed liquid D;
5) feed liquid D is carried out ultra high temperature short time sterilization, obtain lactobacillus fruit juice drink.
Described step 1) in mixing temperature be 25 ~ 80 DEG C, the time is 10 ~ 20min.
Described step 4) in mixing time be 10 ~ 20min, the pressure of homogeneous is 5 ~ 25MPa, and the temperature of homogeneous is 50 ~ 70 DEG C; Described step 5) in the temperature of ultra high temperature short time sterilization be 120 ~ 125 DEG C, the time is 3 ~ 7S.
Compared with prior art, beneficial effect of the present invention is:
(1) lactobacillus fruit juice drink of the present invention is owing to adopting mango juice, so have good local flavor, mouthfeel and color and luster, its higher juice content and streptococcus acidi lactici fermented solution combine, the lactobacillus fruit juice drink that the present invention obtains, juice content is 40 ~ 60%, filled up gaps in market, and this sour milk beverage leaves standstill and lamination can not occur for a long time, the shelf-life is 9 months.
(2) technical indicator of sour milk beverage that the present invention obtains is that in 100g, protein is 0.2 ~ 0.4g, and carbohydrate is 10 ~ 13g, and soluble solid/Brix is 11.5 ~ 13.5, and not fatty.
(3) preparation technology's simple possible of the present invention, adopts existing production line to manufacture, and this preparation method can guarantee that product can not stick with paste wall when sterilization, is applicable to large-scale continuous production.
Further, in the process that mango juice is combined with streptococcus acidi lactici fermented solution, because the acidity of mango is comparatively large, therefore, mouthfeel not like by consumer.Through a large amount of consumer tests, by the consumption of Controlled acidity conditioning agent, regulate the pH value of lactobacillus fruit juice drink between 3.2 ~ 4.9, make sour-sweet than suitable, mouthfeel is better.But when pH value is between 3.2 ~ 4.9; very easily sex change is there is in milk protein in acid system; by a large amount of experimental studies; final discovery when stabilizing agent be pectin (JMJ-CN) and/or sodium carboxymethylcellulose (CMC) time; stabilizing agent and milk protein can well be in conjunction with; play the effect of protected protein matter; thus prevent milk protein sex change; ensure the shelf life stability of product, so adopt pectin (JMJ-CN) and/or sodium carboxymethylcellulose (CMC) as stabilizing agent in the present invention.
