Abstract
The invention belongs to the technical field of processing of vegetable protein, in particular to a process for extracting high-solubility beverage protein. The process comprises the following steps of: mixing raw materials: performing shear mixing on low-temperature bean pulp and water; separating fiber substances out; neutralizing, and adding prolease for sterilizing and modifying; homogenizing under high pressure and performing spray drying; and packaging a finished product and warehousing. The obtained product is an enzymolysis product which has high dispersity, high solubility and small molecular weight, is easy to absorb, and can be applied to protein beverages and physical fitness recovering agents.
Description
Technical field
The present invention relates to the vegetable protein processing technique field, especially is a kind of extraction highly dissoluble beverage protein technology.
Background technology
At present, the lifting of the Along with people's level of consumption is tending towards nutrition, health care, safety, health care, safety, health, recurrence green natural to the requirement of beverage.Vegetable protein beverage is in the best period of a development, has very big development space.Protein ingredient dissolubility in the protein beverage of prior art is lower, easily deposition; And, be difficult for absorption of human body after drinking because the restriction of production technology causes molecular weight of albumen bigger.
Summary of the invention
For overcoming above-mentioned technical problem, the invention provides a kind of extraction highly dissoluble beverage protein technology.
Concrete scheme of the present invention is: a kind of extraction highly dissoluble beverage protein technology is characterized in that: it comprises following step:
1), the mixing of raw material
Low temperature soy meal and 50 ℃～60 ℃ water are pressed 1: 8～1: 10 times of water shear-mixed, regulate pH value 7.0 ± 0.5.
2), separate
Put into seperator,, remove fiber substance, regulate liquid phase pH value to 4.5 ± 0.2, utilize the horizontal spiral separator high speed centrifugation to separate through three separation.
3), mix shearing:
Treat step 2) in the material solid phase separate to be pumped into after broken and mix in the clipper, shear.
4), neutralization: place in the neutralizing tank to neutralize, regulate PH to 7.5～8.2.
5), sterilization modification: add protease in the solution after neutralization, in temperature: 140 ℃～155 ℃, carry out the sterilization modification under steam pressure: 0.7Mpa～0.8Mpa environment.
6), high-pressure homogeneous: as above-mentioned solution to be put into homogenizer, under 200Mpa～300Mpa pressure environment, carry out high-pressure homogeneous.
7), spray-drying: the semi-finished product that after high-pressure homogeneous, obtain get in the spray dryer, under 240 ℃～280 ℃ environment, carry out drying.
8), finished product packing warehouse-in.
Protease addition in the described step 5) is 0.3%～0.6% of a highly dissoluble beverage protein finished product.
The protease in the described step 5) and the reaction time of material solution are: 1.5～2.5 hours.
The present invention has following beneficial effect: the product of gained is the enzymolysis product, and dispersiveness is high, dissolubility is good, is applied to be difficult for deposition in the protein beverage, and molecular weight is less, easily absorption; Can be used for protein beverage, the physical efficiency recovery agent.
