Left and right sugar it is necessary to will remove in this section, in order to avoid under the influence of single step reaction.
2. alkali soaks: plus naoh solution adjusts ph value to 11, maintains 55 DEG C of feed temperature, soaks 1.5～2 little
When, now ph value is about down to 10 about.
Because rice residue protein passes through high-temperature denatured, hydrophobic group exposure, between protein molecule, pass through hydrophobic interaction shape
Becoming a polymer round and round, if not broken up, increasing the contact interface of albumen and water, the effect of back segment enzyme will micro- mutual it be micro-.By
In rice gluten, major part is all alkali solubility albumen, therefore first passes through alkali in this technique and steep so as to swelling open, and carries out appropriate aqueous alkali
Solution, improves its dissolubility.
3. enzyme hydrolysiss: add alkaline protease to carry out in the ratio with rice residue protein butt mass ratio 1: 100
Hydrolysis, reacts and drops to 8.5 to ph.
4. two enzyme hydrolysiss: add neutral protease, reaction in the ratio with rice residue protein butt mass ratio 1: 200
Drop to 6.5 about to ph.
After pre-treatment, protein has been substantially dissolved in water, and now feed liquid ph is alkalescence, by with basic protein
Enzyme is hydrolyzed, and when ph drops to alkalescence, adds neutral protease, depth hydrolysis, when ph drops to slant acidity, feed liquid is sent
To back segment operation.
It can thus be seen that implementing three one-step hydrolysis techniques in technical scheme, the first step adopts basic hydrolysiss, improves
Swellability, improves the effectiveness of enzyme；Second step hydrolysis by novo, in the basic conditions, this enzyme at utmost can send vigor,
Proteolytic enzyme will necessarily cause the decline of ph, if now with ensureing prolease activity it is necessary to maintain ph value 10 about, this
Sample need to add substantial amounts of alkali, increased the free na in feed liquid, increased the load of back segment desalination operation, causes finished product albumen pure
Degree declines, so in the present invention, does not consider to adjust ph value, when ph drops to 8.5, adds neutral protease and carries out
Hydrolysis, enters the optimal ph of vigor of carase again, on the premise of additionally not adjusting ph, has at utmost played monomeric enzyme
Effect.Because different enzymes is also all albumen, it also avoid mutually hydrolyzing between the enzyme that compound enzyme causes, the effectiveness causing simultaneously
Waste.
5. feed liquid separates: feed liquid is carried out separating treatment, takes supernatant, residue returns alkali and soaks workshop section, again soaks,
Improve protein yield.Feed liquid separating treatment of the present invention can adopt centrifugation or filtration separation.
6. concentrate: it is 7 that protein liquid is adjusted ph, and now protein liquid concentration is diluter, for reducing drying cost, passes through in this section
Lifting feed concentration concentrated in vacuo, make solid contain reach 30～50%.
7. add and contain co2+And/or ni2As stabilizer, addition is the 0.2-1% of raw material rice residue weight to the salt of+ion；
8. add pm fungusproof anti-corrosion agent, addition is the 0.01-0.06% of raw material rice weight.
Described alkaline protease is vigor is 20 × 104The alkaline protease of u/g.
