The temperature of described infusion is more than 98 DEG C, and the described infusion time is 4 to 8 minutes.
The present invention is had the benefit that
Described highly concentrated manufacturing soya-bean milk includes the full breaking cellular wall stage: first step: described pulping material is maintained at First temperature range 1 to 10 minute, the first temperature is 70 DEG C to 90 DEG C;Subsequently into second step: institute State crushing knife tool and become serosity with 16000 to 35000 revs/min of rotating shredder of the first rotating speed.By at first step In promote soya cells wall imbibition, fiber and pectin are organized in degeneration under heat effect and soften simultaneously, lose Compactness and support function, it is achieved rupturing of cell wall tissue, after degeneration, the soluble fiber in cell wall is such as Pectin tissue separates from cell wall structure and is dissolved in water, enhances the stably dispersing of dietary fiber, the most carefully Cell wall forms bigger gap so that intracellular nutritional element is able to dissolution, when the first temperature is less than 70 DEG C, Cellulose absorption speed is slow and the Stability Analysis of Structures of cellulose, not enough so that its degeneration softens and discharges solubility meals Food fibre composition, when the first temperature is higher than 90 DEG C, according to Heat transfer law, top layer soybean fiber and cell Internal protein forms interwoven mesh because of overheated and fast denaturation, hinders internal heat absorption and expands, soluble protein Matter cannot preferably dissolution, the most at high temperature continue degeneration be easily formed insoluble protein, add bean milk The unstability of emulsion, thus easily precipitated and separated.After first step, cell wall cellulose with Pectin separates, and completes for the first time " weight reducing ", then to carry out dispersion and fining, such cellulose by second step Along with the reduction of grinding particle size, its retention ability, emulsifiability are all greatly enhanced, to maintaining bean milk suspension Stable, strengthen the concentrated thick sense of bean milk and all have and have very great help, when rotating speed is less than 16000 revs/min, it is impossible to fill Point extracting intracellular nutrient, and cellulose grain is excessive, stablizing of unfavorable bean milk emulsion, cellulose and not Broken cells group is precipitated because of action of gravity, affects bean milk quality, and the nutritional amt such as protein, solid content is relative Relatively low, when rotating speed is higher than 35000 revs/min, it is easily destroyed the emulsion stabilising system of formation, and protein Exposure the most fully dispersed with fat, in high-speed rotation, is easily combined generation oxidizing brown stain reflection with oxygen, Protein particularly soluble protein content, makes bean milk color and luster dimmed simultaneously, affects organoleptic quality. So, complement each other between first step and the second step in the full breaking cellular wall stage, lack any one step The most not all right, and must be first step before second step, only enter again after first step Row second step just can make the micronized degree of dietary fiber be greatly improved, and the dispersibility of dietary fiber and Retentiveness is also significantly improved, so that the emulsion of bean milk is highly stable, and bean after slurrying completes Slurry is not easy to lamination occur, and in a word, the soymilk concentration prepared by said method is high, is difficult to layering, And it is good in taste.
Described second step also includes that pulping material described in heating element heats is warming up to the second temperature and is maintained at Second temperature carries out the process pulverized, and the second temperature range is 90 DEG C to 100 DEG C.Owing to second step being incited somebody to action Pulping material is pulverized, it is not necessary to the problem considering to hinder internal heat absorption and expand, and research shows the highest meals of temperature Dilatancy and the retentiveness of fiber are the strongest, are more beneficial to stablizing of bean milk emulsifying, when temperature is less than 90 DEG C, and meals The retentiveness of food fiber can decline, and the retentiveness of dietary fiber declines and the most easily forms precipitation, solid content Corresponding decline, therefore carry out pulverizing and can promote the dilatancy of dietary fiber and hold by being warming up to the second temperature Aqueous, reduces bean milk layering probability further.
Described first step also includes coarse pulverization process, and described crushing knife tool is with less than the first rotating speed rotating shredder; Or also including coarse pulverization process after described first step before second step, described crushing knife tool is to be less than First rotating speed rotating shredder.So, increase the contact area of Semen sojae atricolor and water in the first step, be conducive to big Bean cell wall imbibition, promotes that fiber and pectin are organized in degeneration under heat effect and soften, loses the most further Removing compactness and support function, it is achieved rupturing of cell wall tissue, fiber after degeneration and pectin tissue are from carefully Cell wall structures separates and is dissolved in water, further enhancing the stably dispersing of dietary fiber.
The coarse pulverization stage was also included: described crushing knife tool is with less than the first rotating speed rotation before the described full breaking cellular wall stage Turn and pulverize.So, before the full breaking cellular wall stage, increase the contact area of Semen sojae atricolor and water, thus strengthen further The beneficial effect that first step is brought, and also have the crush efficiency of interests second step, so that meals The micronized of food fiber promotes, and reduces the layering probability of bean milk further.
Described crushing knife tool is with 5000 to 8000 revs/min of rotating shredder, and described grinding time is 60 to 150 seconds. So, cracking soybeans can be become 1/10~1/20 soybean particle, the beneficially imbibition of soya cells wall, The nutrient making Semen sojae atricolor separates out.
Also included that described in described heating element heats, pulping material was to the first temperature before the described full breaking cellular wall stage Process.So, Semen sojae atricolor can have the time imbibition of abundance, beneficially nutrient to separate out.
Pretreatment stage was also included: pulping material described in described heating element heats before the described full breaking cellular wall stage To more than 60 DEG C, Semen sojae atricolor is taken off by described crushing knife tool with 3000 to 5000 revs/min of rotations for 10 to 30 seconds Skin processes.So, it is achieved soybean peeling, promote cotyledon cell water suction, promote the activation of intracellular nutritional element, Thus it is prone to release, ensure the integrity of soybean particle, it is to avoid the generation of beany flavor composition simultaneously.Semen sojae atricolor Nutrition is primarily present in cotyledon cell, and Cortex beans Middle nutrition is little, but Cortex beans is that in Semen sojae atricolor content of cellulose is Many, the hardest tissues, hinder the water suction process of cotyledon in water absorption course, hinder the dissolution of nutrient simultaneously. Semen sojae atricolor is carried out decortication and processes the water suction of favourable cotyledon cell and endotrophic activation thus beneficially breaking cellular wall dissolution. The Cortex beans simultaneously taken off increases the contact surface with water, favorably conducts heat, beneficially Cortex beans fiber and the change of pectin Property soften, thus favorably grind and exempt from filter to cellulose is broken during breaking cellular wall.Semen sojae atricolor water absorption course is that imbibition is made With water suction, epidermis imbibition at first, the main component of epidermis is cellulose and pectin, and absorption speed is fast, Thus quickly unfold formation gauffer, and cotyledon cell is mainly by the suction of the nutrient substance such as intracellular protein Water and expand, because of the obstruct of seed coat, rate of water absorption is slow, and the difference of this rate of water absorption makes seed coat short with cotyledon Property departs from temporarily.Now utilize 3000~5000r/min rotating speed stirring decortications, it is easy to make Cortex beans carry out with cotyledon Separate.Rotating speed is too low, it is impossible to fully to soybean peeling, rotating speed is too high, and shearing force is excessive, destroys cotyledon thin Born of the same parents' integrity, easily to beany flavor generation.Best Times is 10~30s, and the time is too short, it is impossible to fully to Semen sojae atricolor Decortication, overlong time, destroy cotyledon cell integrity, easily to beany flavor generation.
The temperature of described infusion is more than 98 DEG C, and the described infusion time is 4 to 8 minutes.So, by enduring Cook off except the phytic acid in bean milk, saponin.Infusion process simultaneously makes the protein of release, lipomicron in bean milk Decompose further, promote generation and the release of flavor component, be more beneficial for digesting and assimilating simultaneously.
