The manufacture method of protein hydrolyzation sauce
The present invention relates to contain the manufacture method of monochloro propane diols (below be called " MCP ") less than the improved protein hydrolyzation sauce of 5ppb.That just relate in more detail that Different Nitrogen Concentration is very high, taste is very dense, tone is light, no empyreumatic taste, chemicals stink, the peculiar stink of amino acid, sapid, the manufacture method of the protein hydrolyzation sauce of the economy that drug dosages such as NaOH and hydrochloric acid are few.
May problematic MCP on food hygiene known be the accessory substance that produces in the decomposed solution during with hydrochloric acid hydrolysis at plant protein material, should reduce its concentration in decomposed solution as far as possible.
In the past, as the method that reduces MCP, known have the plant protein material hydrochloric acid hydrolysis, adding alkali in the gained hydrolyzate neutralizes, further adding alkali regulates more than the pH8.0, at high temperature keep the method for certain hour with alkali treatment then, but the method having several shortcomings, is not gratifying method.
That is, the spy opens " manufacture method of protein hydrolysate " flat 2-150241 number, with the vegetable protein hydrochloric acid hydrolysis, has then put down in writing the above-mentioned alkali treatment of carrying out by the following method in the method with alkali treatment.
Promptly in hydrolyzate or its filtrate, add highly basic, be adjusted to the scope of pH8~14.
But the method has only been put down in writing pH and can have been regulated in 8~14 broad range, and the very low range of pH8.2~8.7 is not adopted in record, and does not show the effect that this scope can reach.
Research according to present inventors, in the scope of pH8~14, can not eliminate MCP during less than 8.2 makes it less than 5ppb, otherwise, surpassing at 8.7 o'clock, the tone of vegetable protein hydrolyzation sauce is too dense, the consumption of NaOH increases, become uneconomical, foreign odors such as chemicals stink adhere to, and can not obtain the baste of the mellow high Different Nitrogen Concentration of taste.
In addition, the spy opens flat 7-184557 number " manufacture method of vegetable protein hydrolyzation sauce " and when having put down in writing alkali treatment hydrolyzate is adjusted to pH8.8~9.3.
But, according to present inventors' research,, have that the tone that makes hydrolysate thickens, the consumption of NaOH increases, the uneconomical and shortcomings such as baste that can not obtain the mellow high Different Nitrogen Concentration of taste though the method can be reduced to MCP not enough 5ppb.
The objective of the invention is to, obtain that MCP is that can not detect, that Different Nitrogen Concentration is very high with the determination method of detection limit 5ppb, taste is very dense, tone is light, no empyreumatic taste, chemicals stink, the peculiar stink of amino acid, sapid, and the protein hydrolyzation sauce of the few economy of drug dosages such as NaOH and hydrochloric acid.
Present inventors further investigate in order to solve above-mentioned problem, found that, for with the plant protein material hydrochloric acid hydrolysis, then carry out the manufacture method of the vegetable protein hydrolyzation sauce of alkali treatment, in alkali treatment, the method with " adding highly basic in hydrolyzate or its filtrate; regulate pH8.2~8.7; contact with water vapour and carry out heat treated in open system " can solve above-mentioned problem, thereby finish the present invention.
Promptly, the present invention is exactly a kind of manufacture method of protein hydrolyzation sauce, with plant protein material with hydrochloric acid hydrolysis, then handle with alkali in the method for making protein hydrolyzation sauce, it is characterized in that above-mentioned alkali treatment is in pH8.2~8.7 time, open system, carries out heat treated with the water vapour contact.
For enforcement of the present invention, manufacture method according to common vegetable protein hydrolyzation sauce, (1) at first vegetable proteins such as defatted soybean, wheat gluten, corn gluten is hydrolyzed with hydrochloric acid, then (2) highly basic such as adding sodium carbonate and/or NaOH in the hydrolysate of gained or its filtrate carry out neutralization operation.
In the present invention, carry out above-mentioned in and the time, in hydrolyzate or its filtrate, add highly basic, regulate pH8.2~8.7, in open system, contact and carry out heat treated with water vapour.
In the present invention, this alkali treatment is of crucial importance, during pH less than 8.2, MCP is reduced to below the 5ppb.
Otherwise, if pH surpasses 8.7, then there is the tone of vegetable protein hydrolyzation sauce too dense, the consumption of NaOH increases, and becomes uneconomical, and foreign odors such as chemicals stink adhere to, and can not obtain the shortcomings such as baste of the mellow high Different Nitrogen Concentration of taste.
In addition, in open system, water vapour contact heating is extremely important, contacts when heating with water vapour in open system, can eliminate empyreumatic taste, chemicals stink and amino acid whose peculiar foreign odor effectively by the utmost point.
As water vapour, saturated vapor, superheated vapour, other water vapour etc. are for example arranged, preferably use saturated vapor, because of it can be in the raise temperature of sample of short time.
Sample temperature is 50~100 ℃, and particularly 80~97 ℃, the retention time is 6~24 hours, and particularly 10~20 hours, this was very important.If sample temperature is lower than 50 ℃ then processing time and prolongs, increase if surpass 100 ℃ then water vapour consumption, the moisture in water vapour source enters goods, is diluted by water, can not get the decomposed solution of high Different Nitrogen Concentration.
Concrete grammar as heat treated, can use arbitrarily with hydrolyzate 50~100 ℃ down keep 6~24 hours after the methods of cooling rapidly, stop after 90~100 ℃ heating, be incubated and can make sample temperature remain on the method for placing under the condition more than 50 ℃ 6~24 hours while perhaps hydrolyzate is heated to.
For the processing time,, can adhere to empyreuma, become significantly painted, undesirable if instead surpass 24 hours and then decompose page or leaf if be less than 6 hours then MCP can not be reduced to below the 5ppb.
So the hydrolyzate after the alkali treatment of gained is adjusted to pH4~6, particularly pH4.5~5.5 with hydrochloric acid, can be as required decolours with active carbon etc., reaches protein hydrolyzation sauce.
Preferably pH is transferred to 4.5~5.5, can obtain the extraordinary baste of local flavor this moment.
