2) stabiliser solution preparation: stabilizing agent, sweetener are dissolved in respectively in the hot water of 65 ℃~75 ℃;
3) batching: by protein solution, step 2 described in step 1)) described stabiliser solution and the mixing of other raw material, be cooled to normal temperature, make final solution pH value reach 4.3~7.0, make mixed liquor;
4) by edible nourishing colloidal solid and above-mentioned mixed liquor on-line mixing, stir, sterilization filling.
In the preparation method of above-mentioned protein drink, when step 3) is prepared mixed liquor, if mixed liquor pH value is nonconforming, can use above-mentioned acid to regulate pH value.
Particularly, the nutritional granular production craft step the present invention relates to is as follows:
The preparation of A colloidal solution:
Water-soluble colloid is mixed, add stirring and dissolving in the water of 70~85 ℃.
Fruits and vegetables powder, dietary fiber, natural sweetener and natural colouring matter are added in the above-mentioned water-soluble glue liquid solution being uniformly dissolved.
The preparation of B carrier solution:
Converted starch is dissolved in the water of 80~85 ℃ to hydration 15 minutes, then add vitamin, mineral matter and plant extracts to stir, more all add above-mentioned colloidal solution to mix carrier solution to be cooled to normal temperature for subsequent use.
The preparation of celite solution:
A certain amount of calcium salt is dissolved in the water of normal temperature, adds certain acidity conditioning agent that salting liquid pH value is adjusted to 3.5~4.0.
The preparation of D nutritional granular:
By the mixture of A colloidal solution and B carrier solution and celite solution, mix according to the ratio of 1:1~1:2, hybrid mode by compressed air diaphragm pump by A, B solution mixture is squeezed into the round-meshed spherical shower nozzle of surperficial tool, spray in the celite solution of slow stirring through shower nozzle different directions from salting liquid tank, in glue and salting liquid, calcium ion and hydrogen ion generation gelatification form the nutritional granular of a certain size and shape, particle coagulation forming 30 minutes in salting liquid, this particle and salting liquid are carried out to isolated by filtration, isolated particle can be by helicoidal pump and above-mentioned feed liquid according to on-line mixing according to 5%~10% percentage by weight, the feed liquid constant volume blending that stirs, again through 121 ℃/4 seconds UHTSs, sterile filling, produce the drink that contains various Different Nutrition particles.
The present invention first utilizes converted starch solution to dissolve in conjunction with mineral matter, vitamin, plant extracts, again fruits and vegetables powder, water insoluble dietary fiber, natural sweetener and natural colouring matter are dissolved in water-soluble glue liquid solution, after above-mentioned two parts colloidal solution is mixed, add and in acid calcium solution, form water-insoluble gel nutritional granular by certain way.Again this particle is evenly added to online and in drink semi-finished product, mixed sterilizing and carry out sterile filling by helicoidal pump, produce the various drinks that contain Different Nutrition composition particle.Because LM, sodium alginate (G/M ratio value is higher), low-acyl gellan gum are combined strongly and are formed gel with calcium ion under certain pH conditions, and this gel has certain heat-resisting, acidproof, dissolubility resistent.Squeeze into the spherical shower nozzle in salting liquid tank containing nutritious colloid mixed solution by membrane pump, glue enters in the salting liquid of slow stirring from different directions by spherical shower nozzle circular hole, calcium ion and hydrogen ion generation gelatification in glue and salting liquid, form the colloid nutritional granular of a certain size and shape, this particle coagulation forming 30 minutes in salting liquid, by particle, by isolated by filtration, particle diameter is approximately 3~5mm.Particle filtering is separated, the particle of separation is mixed with protein drink base-material and carries out sterilization filling online by auger conveyor, produce the protein drink that contains various Different Nutrition particles.
Edible nourishing colloidal solid of the present invention can be in drink stable existence, in particle, nutritional labeling is stable, drink mouthfeel and local flavor are not affected by particle nutritional labeling, have guaranteed that drink quality is constant.The combination of nutritional labeling and colloid can prevent nutritional labeling dissolved destruction and loss effectively.Wherein, colloidal solution gel effect in acid calcium solion is better, and the combination coating effect of converted starch solution and vitamin, mineral matter and plant extracts is better simultaneously.
The present invention by regularly detect granule content in protein drink and change and drink feed liquid in the changes of contents of nutrient, judge the stability of particle in drink solution and the particle stability in conjunction with nutrient.Testing result shows, nutritional granular protein drink of the present invention compared with similar products tool has the following advantages:
1, in particle, the content of nutrient is more stable;
2, the particle containing in drink is more stable;
3, in particle, can contain different nutrients;
4, nutrient does not affect beverage quality;
5, improved the nutritive value of drink particle.

The quality evaluation of embodiment 5 products of the present invention
Take embodiment 1 as example, the protein drink of natural fruit and vegetables grain, dietary fiber, vitamin, mineral matter that same base-material is directly added to equivalent amount is as a comparison sample, the nutritional granular protein drink of preparing with various embodiments of the present invention carries out sense organ and flavor evaluation, and evaluation result is as follows:
Describe and can find out that drink particle characteristic of the present invention and drink characteristic do not change substantially from above-mentioned evaluation, solved the deficiency that natural fruit and vegetables grain, dietary fiber, vitamin, the mineral matter drink of direct interpolation equivalent amount exist.
Nutritional granular protein drink of the present invention and same drink base-material are directly added to natural fruit and vegetables grain, dietary fiber, vitamin, the mineral matter protein drink of equivalent amount places and contrasts for 3 months under normal temperature condition, every month observed and recorded drink granule content, drink protein stability (centrifugal), drink pH value, drink dietary fiber content, drink vitamin content, drink content of mineral substances, investigate nutrient stability three aspects: in granule stability, drink protein stability, particle, in every 100 grams of drinks, various component content records are as follows:
The particle nutrient detection method the present invention relates to adopts indirect method: by dietary fiber, vitamin, the content of mineral matter and the ratio of salting liquid and granular mass in salting liquid after detection filtering particle, can calculate the nutrient content comprising in particle.
The stability of the particle nutrient the present invention relates in drink calculates the variation of nutrient content in particle by dissolving the particle dietary fiber, vitamin and the content of mineral substances that in indirect detection drink feed liquid, thereby judges the ability of particle embedding in conjunction with nutrient stability.
According to the present invention, solution pervasion nutrient content detection case in three months shelf life endoparticle content of product and drink feed liquid, illustrates that particle is basicly stable, and in particle, better, particle drink meets target level of product quality in nutrient embedding protection.
