comparative example 1.
The basis of embodiment 1 changes AMS into beta amylase, and all the other raw materials and method parameter are all identical with embodiment 1.
comparative example 2.
On the basis of embodiment 8, enzymolysis duration is adjusted to 150 minutes, raw material and all the other method parameters are all identical with embodiment 1.
product checking.
one, the detection of product viscosity.
Product viscosity is the key character index of product, and especially for the modulation breast that with the addition of cereal-granules, viscosity determines whether cereal-granules can even suspension key factor in the product.The modulation milk product of the interpolation enzymolysis cereal-granules produced with above embodiment is test specimen, carries out viscosimetric analysis to it.
Method: Viscometry instrument is selected from BROOKFEILD (DV-II+ProVISCOMETER), rotor is No. 62 rotors, rotating speed 60rpm/min, temperature 25 DEG C.Finished product viscosity is by after cereal-granules filtering in product, remains the viscosity of newborn base-material; Finished product viscosity is had any different according to the difference of product standing time in shelf life again.Now finished product viscosity is detected by finished product viscosity of dispatching from the factory, month finished product viscosity, two months finished product viscosity, three months finished product viscosity, four months finished product viscosity, five months finished product viscosity and a six months finished product viscosity.
The results are shown in Table 1.Two months finished product viscosity of commercially available modulation breast obviously increase as can be seen from Table 1, be increased to maximum by three months, within latter three months, viscosity reduces, viscosity is poor at shelf life internal stability, the products taste causing consumer to taste period at different shelf is inconsistent, can not bring the mouth feeling experience of stable and consistent to consumer.Embodiment 1-9 viscosity in the shelf life of 6 months is more stable as can be seen from Table 1, can meet the stability requirement of system suspension cereal-granules, modulates the mouth feeling experience that can better be supplied to consumer's stable and consistent compared with breast with commercially available.
Although detect after the product viscosity cereal-granules that has been filtering, inventor finds some remain in testing sample by adding viscosity that cereal-granules brings in experimentation.AMS is changed to beta amylase by comparative example 1 on the basis of embodiment 1, found that beta amylase is not contributed finished product viscosity; And embodiment 1 uses the AMS being, found that AMS can improve finished product viscosity, the simultaneously requirement just met finished product viscosity that also controls of the enzymolysis time of embodiment 1; And enzymolysis duration is extended to 150 minutes by comparative example 2 on the basis of embodiment 8, cause the loss of product viscosity.

two, the inspection of products taste.
Method: random selecting 300 people forms test crowd, to carry out the training of relevant deliberated index marking to it before tasting, make each panelist understand each index there is difference to point scope, index time to the spacing of dividing.After trial test by the mode of blank marking to its local flavor (10 points), color and luster (10 points), mouthfeel (10 points), chewability (10), swallow comfort level (10 points) and overall preference degree (10 points) is given a mark, mark is higher, and effect is better.Wherein mouthfeel index evaluates the comfort level of overall product to tongue and oral sensation; Can chewability evaluate entrance drink cereal-granules, could be perceived as solid and exist, if sting the need of tooth and need tooth to sting just to chew rotten solid to there is the dynamics used.Swallowing comfort level is evaluate the sensation of product oral cavity and throat in the process of swallowing and after terminating, and product is more moist, not puckery, not coarse, swallows and feels more comfortable.
Carry out statistical analysis to trial test result, result is as shown in table 2.Result shows: embodiment of the present invention 1-9 product in local flavor, mouthfeel, chewability, swallow in comfort level and overall preference degree and be obviously better than commercially available modulation milk product.The modulation milk product difference that commercially available modulation milk product and embodiment 1-9 produce on color and luster is little.This illustrate the modulation breast of the interpolation cereal-granules produced by the present invention in local flavor, mouthfeel, chewability, swallow in comfort level and meet consumer demand greatly, it is newborn that people exceed common commercially available modulation far away to its fancy grade.
AMS is changed to beta amylase by comparative example 1 on the basis of embodiment 1, and beta amylase is inappropriate sugariness adding product on the one hand, affects Total Product local flavor, and the cereal-granules mouthfeel on the other hand after beta amylase enzymolysis is not good enough; And embodiment 1 uses the AMS being, what enzymolysis time controlled meets our requirement to finished product viscosity and sugariness and overall local flavor just; And enzymolysis duration is extended to 150 minutes by comparative example 2 on the basis of embodiment 8, the prolongation of enzymolysis time makes the cereal-granules mouthfeel after enzymolysis not good enough.Comparative example 1 and 2 similarly makes cereal-granules mouthfeel become coarse disagreeable to the taste by soft glutinous strength of chewing, popular says, the same with cereal bran with the cereal-granules mouthfeel that 2 obtain by comparative example 1, can feel when the finished product made is drunk that grain husk scrapes throat, seam of getting stuck between the teeth, having no joyful sense can say.The result of table 2 also show the hobby tendency of consumer, clearly, comparative example 1 and 2 swallow comfort level and overall preference degree score is lower.

three, the detection of cereal-granules distributing homogeneity.
Detection method: under normal temperature (25 DEG C) condition, static observation 160 days, cuts off packaging at set intervals and topples over sample, every sample packet is evenly divided into upper, middle and lower-ranking, measure wherein cereal-granules content respectively, thus the uniformity of cereal-granules distribution in testing product.Wherein the mensuration of cereal-granules content comprises the following steps:
(1) take out whole sample packet to be measured, topple over successively as corresponding beaker by 1/3rd volumes gently, and record the weight of mixture in each beaker, be denoted as A;
(2) 120 object metallic screens are clean with purified rinse water, drain, weigh, be denoted as B;
(3) modulation of the corresponding number of plies of taking out breast and cereal-granules are wherein poured on metallic screen together, transparent to trickle color with purified rinse water, drain, claim oversize weight, be denoted as C;
(4) cereal-granules content calculates as follows:
Cereal-granules content (%)=(C-B)/A × 100%.
Result is as shown in table 3.As can be seen from Table 3, obviously there is the many problems of few, the middle lower floor in upper strata in commercially available modulation newborn upper, middle and lower layer cereal-granules content distribution, and the cereal-granules content difference simultaneously between same batch of different bag is apart from larger; Comparatively speaking, the distribution of the cereal-granules of embodiment 1-9 is just relatively more even, and between the difference bag of same batch cereal-granules content without obvious gap; Illustrate that the breast of the modulation containing cereal-granules particle distribution uniformity that embodiment 1-9 produces is significantly better than commercially available prod.
AMS is changed to beta amylase by comparative example 1 on the basis of embodiment 1, find AMS to change to beta amylase in experimentation to make the amount of cereal-granules remainder comparatively embodiment 1 is few, cereal-granules global density lightens, cereal-granules mostly swims in the middle and upper part of product, causes skewness; And enzymolysis duration is extended to 150 minutes by comparative example 2 on the basis of embodiment 8, the cereal-granules global density after this makes enzymolysis lightens, and cereal-granules mostly swims in the middle and upper part of product, skewness.Also the upper lower floor of comparative example 1 and 2 phenomenon pockety can be found out by table 3.
