The determination of 2.2 rice in steep times
Take 200g rice to be soaked at room temperature, under different soak times, determine the quality of rice, determine big The water absorption rate of rice.
Influence of the 2 different soak times of table to rice water absorption
The degree of rice water suction is represented with water absorption rate Q:
Q0Weight (gram) before ----rice in steep;
Q1Weight (gram) after ----rice in steep;
Rice reaches saturation state in one hour of immersion or so water absorption as can be seen from Table 1, no matter rice soaks afterwards How long bubble is all without the quality for influenceing rice.After rice water absorption reaches saturation state, rice becomes soft than before, favorably In grinding finer and smoother and uniform by rice during defibrination.
2.3 different meter influences of the water ratio to rice gelatinization degree
Meter Shui ratio is different, and the gelatinization effect of rice also differs, in order to study the water rice of different proportion to being gelatinized journey The influence of degree, this experiment are studied rice using control single factors quantity method.
Different meter influences of the water ratio to rice gelatinization degree of table 3
Conclusion:When the content of rice and water is more than 1:When 6, rice Rice & peanut milk is excessively sticky, and precipitation is more, can not stir, and causes Make half steaming, caking is more, and gelatinization is uneven, when less than 1:When 6, rice Rice & peanut milk is again too dilute, lacks the distinctive rice of rice It is fragrant.
The influence of 2.4 different temperatures and time to rice gelatinization degree
For the gelatinization point of starch more than 53 DEG C, starch is broken down into the list for being more easy to be absorbed and utilized by the body after gelatinization Sugar, influence of the different gelatinization points to the quality color and luster of rice are different.The rice of identical conditions is carried out at different temperatures Gelatinization, the experimental results are shown inthe following table:
The influence of the different temperatures of table 4 and time to rice gelatinization degree
As can be seen from Table 4 when gelatinization point is long, rice Rice & peanut milk becomes very thick, and with spoon it is difficult to stir, caking is very More, quality is uneven, when gelatinization point is too short, is gelatinized not exclusively, and solution is very dilute, there is half-cooked situation.Pasted under 90 degree When changing 10 minutes, solution forms pasty state, and more uniform, and no caking phenomenon produces, and gives out light meter Xiang, and effect is best.
Influence of the 2.5 alpha-amylase dosages to rice Rice & peanut milk hydrolysis result
Complete Rice & peanut milk will be gelatinized and be cooled to 70 DEG C or so, 70 DEG C of thermostat water bath is placed in after addition alpha-amylase In stir, until without caking exist.(hydrolysis degree of starch is detected with iodine solution every 5min, until the complete water of starch Solution).
Because containing substantial amounts of starch in the rice being gelatinized, solution is set to form pasty state, mobility is very weak, so we are sharp Decomposed with alpha-amylase, make the viscosity of solution reduce, become liquefying starch.(if the solution after liquefaction also has a little particle In the presence of can be filtered with the sieve of 60 mesh).
Influence of the enzyme dosage of table 5 to starch
Note:The dosage of alpha amylase is the quality according to rice as addition in table.
Conclusion:By in table it can be seen that when in 20min, in the case that enzyme dosage is 0.4%-0.6%, it is possible to by rice Rice & peanut milk liquefaction is complete, makes rice Rice & peanut milk without particle and caking, and good fluidity, is influenceed on the contrary when alpha-amylase addition is excessive big The flavor of rice Rice & peanut milk, i.e. alpha-amylase smell are excessive to mask the distinctive rice perfume of rice and color and luster, in summary, is in enzyme dosage Liquefied effect is best during 0.4-0.6%.
2.6 allotment
The rice Rice & peanut milk solution digested is added after milk, white granulated sugar and remaining water and allocated, if after enzymolysis Rice & peanut milk solution also have trickle particle, it can be filtered with 60 mesh sieve cloth, the Rice & peanut milk solution particles after filtering are tiny, matter Ground is uniform, i.e., by solution proportion 1:2 cow's milk and 4% white granulated sugar are allocated (can be stirred using electric mixer Mix), it is sufficiently mixed with Rice & peanut milk solution.Table 6 below is influence of the cow's milk addition to rice rice milk beverage flavor.
Influence of the cow's milk addition of table 6 to flavor
Note:Cow's milk addition is using the water added in rice as index.
Conclusion:Cow's milk can influence the flavor of rice milk too much, and rice milk can be made to become very thick again, when the addition of milk is water During half, dilute denseness of rice beverage is moderate, and mouthfeel is lubricious, fine and smooth, no granular sensation, had not only distributed dense frankincense taste but also had been mingled with Light rice fragrance, mouthfeel and color and luster are all good.
Influence of the sugared addition to Fermented flavor:
In addition cow's milk and then the sugared flavor that can improve rice rice milk beverage is added, in fermentation process afterwards Raw material can be provided for lactobacillus ferment, moreover it is possible to tart flavour caused by neutralizing the fermentation of rice rice milk, give people a kind of pleasant mouthfeel, separately Outer sugared addition can also influence the stability, quality and color and luster of rice rice milk fermented beverage to a certain extent, in rice rice milk Played an important role in the fermentation process of beverage.
Influence of the 7 sugared addition of table to Fermented flavor
Conclusion:When the addition of sugar is very few, the sweet taste unobvious of rice milk beverage, taste is relatively simple, due in beverage The also presence of lactose, so when the amount of sugar is slightly more, obvious sweet taste will be produced, is shown by table 7:When the amount of addition sugar exists When 4%, the rice fragrance and frankincense taste of rice rice milk beverage are strong, and sugariness is moderate, good in taste, unique flavor.
Influence of 2.7 homogenization cycles to rice beverage stability
The present invention uses second homogenate, and homogenizing temperature is maintained at 70 DEG C or so, and homogenization pressure is controlled in 30MPa, each equal Matter time 5-10min.Homogenizer is paid attention to using preceding needing to be cleaned with hot water, and the pointer of control pressure table not fluctuate widely, and close Close after power supply and again spill homogeneous liquid from preceding liquid receiving port.(homogenizer will contain liquid at the moment in use, to prevent sky Gas enters, and influences homogenizing effect)
Influence of the homogenization cycles of table 8 to product stability
Conclusion:, there is the phenomenon being layered in product of the effect of homogeneous twice than homogeneous once it can be seen from above-mentioned table 8 Few, the precipitation of appearance is lacked, and illustrates that homogeneous can make the particle of solution smaller twice, and solution is evenly, and dissolving is more abundant.Equally from Upper table can be seen that identical homogenization cycles, and the effect of average is best under 30MPa pressure, and product is almost without layering and precipitation Phenomenon produce, the stability of product is best.So control the twice homogenization effect under 30MPa best the homogeneous of product.
Influence of 2.8 homogenizing times to rice beverage stability
Influence of the homogenizing time of table 9 to product stability
Conclusion:It can be analyzed in homogenization pressure under for 20MPa by above-mentioned table 9, with the increase of homogenizing time, precipitation Gradually improved with lamination, but deposited phenomenon is still present.Under 25MPa as 20MPa situation, but relative to 20MPa product stability is better, and the homogenizing effect of product is best under conditions of 30MPa, 20min, does not produce precipitation Lamination, that is, in the homogenizing process of product, homogenization pressure will be controlled under 30MPa, the homogeneous under second homogenate 20min, product are most stable.If, can be excessive due to pressure more than 30MPa, injection, which occurs, in high pressure homogenizer to be shown, and pressure It is unstable, cause product to be lost in excessive.
