Description
Technical field
The invention belongs to dairy products technical fields, and in particular to a kind of yoghourt stabilizer containing soybean polyoses, it is in Yoghourt
In application and Yoghourt preparation method.
Background technology
Drinking yoghourt is mainly characterized by that low viscosity, good fluidity, delicate mouthfeel be smooth and sour and sweet palatability, can be used as one kind
Convenient, salubrious, nutrition beverage is drunk, and is a fastest-rising type in Yoghourt category in recent years, especially leading high egg
White drinking yoghourt has been increasingly becoming the essential part of ordinary meal.Drinking yoghourt in process due to
Confrontation curdled milk stabilising system damages, therefore whey precipitation, the flocculation of protein, aggregation or precipitation easily occurs, even
There is lamination.So drinking yoghourt has larger dependence to the protection of stabilising system.
Different stabilizers has a certain difference in terms of improving drinking yoghourt quality, simple to be stablized using a certain
Agent tends not to achieve the desired purpose, and therefore, stabilizer is carried out compounding appropriate, may will produce certain synergistic effect,
To ensure the stability of drinking yoghourt.
Soybean polyoses are using Soybean Meal as raw material, by water soluble acid made of the techniques such as extraction, purifying, sterilizing, drying
Property polysaccharide.It is to be made using poly- rhamnose galacturonic acid and polygalacturonic acid as main chain, araban and poly- galactolipin
It is similar with chondritic body for side chain.Soybean polyoses have relatively low viscosity and higher stability in aqueous solution, and
By heating and salt ionic concentration is influenced very little, there is good stablizing effect to yogurt, it almost can be with currently used height
Methoxy group pectin compares favourably.Simultaneously as soybean polyoses hardly increase viscosity, the salubrious mouth of drinking yoghourt is also gived
Sense.
Soybean polyoses are anion polysaccharide of the structure similar to pectin, can stablize casein in acid condition, and have
The excellent characteristics of low viscosity can be used for preparing light milk beverage.The key of soybean polyoses stable acidic milk beverage is for I
The neutral branched polysaccharides of uncle's sugar or galacturonic acid composition, when soybean polyoses are adsorbed to casein surface, in longer
Property carbohydrate side chain provide the effect of good steric hindrance, stabilize casein system.Soybean polyoses pH be less than 4.2 when, not with
Casein interacts, and when pH is less than 4.2, the stability of soybean polyoses is better than pectin.These difference are the two point
Caused by minor structure difference, soybean polyoses carry a small amount of charge and longer tral sugar side chains, are adsorbed with casein
Afterwards, neutral branch can provide stronger interaction.

To sum up, the present invention provides the drinking yoghourt of refrigeration, clean taste.For this purpose, being pursued from mouthfeel and product quality
Level on, inventor has done subjective appreciation test.Results of sensory evaluation shows that the mouthfeel of drinking yoghourt is to influence consumer
An important factor for fancy grade.The fermenting aroma of full-cream drinking yoghourt is stronger, and consumer is more partial to high protein
Drinking yoghourt.Comparative example 1 shows that stabilizer additive amount is very few, be easy to cause bleed, and product stability is poor;2 table of comparative example
It is bright, pectin and carboxymethyl cellulose are compounded merely, stability is poor, and the effect compounded with soybean polyoses is not achieved.Possible cause
It is the electrostatic repulsion of pectin stabilization casein non-phosphopeptides and the space bit that carboxymethyl cellulose is generated in casein adsorption
Inhibition effect, the active force of the two stabilizing sour milk are less than active force when being compounded jointly with soybean polyoses;Comparative example 3 is using general
The common stabilizer of logical Yoghourt, it can be seen that under the premise of stable system, add the drinking yoghourt mouthfeel of soybean polyoses more
Add salubrious, viscosity is relatively low, this is because soybean polyoses while the effect stabilizing sour milk of steric hindrance by that can not increase body
The viscosity of system, to keep drinking yoghourt mouthfeel salubriouser.
The yoghourt stabilizer of the present invention is pressed using soybean polyoses, pectin, carboxymethyl cellulose as compound stabilizer in application
It is uniformly mixed according to ratio.The structure of wherein soybean polyoses is similar with pectin, but soybean polyoses contain more galacturonic acids
And branched structure, good water solubility have good thermal stability, chemical stability, are especially used in compounding with other colloids
When, it can be precipitated or be layered with effective solution drinking yoghourt whey and the problems such as mouthfeel is sticky, also having makes to drink type acid
The effect of milk clean taste.
