Abstract

A wheat flour improver not containing Br salt which is a cancerogenic substance is prepared from azomethylamide (ADA) or ascorbic acid and enzyme preparation. Its advantages are high safety to human body and high effect on improving toughness, structure and surface finish quality of wheat flour particle.

Description

A kind of flour improver and preparation method thereof

Technical field the present invention relates to a kind of flour improver, does not particularly contain the flour improver of bromate.

Background technology bromate (as potassium bromate) has a wide range of applications in flower characters and Flour product quality-improving as a kind of oxidation gluten-strengthening agent.Because effective, the low price of the strong muscle of bromate oxidation makes it as the existing long history of flour inorganic agent.

Be used for baking industry in the U.S. for the first time in 1914, nineteen forty-one is used by the FDA approval.Recent studies show that bromate is a kind of carcinogen of poisoning gene, and health is formed great threat, so 1992 are banned use of in the flour inorganic agent by WHO.At present overwhelming majority of countries and China Hong Kong, Macao and Taiwan ban use of bromate as the flour inorganic agent in succession, but domesticly still continue to use in flour with the 30mg/kg consumption.

Mainly substitute bromate at present abroad with glucose oxidase, but cost an arm and a leg, domestic insider almost refuses to use, also useful abroad azodicarbonamide (ADA) and microencapsulation ascorbic acid mix to make and are used for doing bromine salt substitute, but microencapsulation ascorbic acid cost is also than higher, and the enthusiasm that the client accepts is not high.

Summary of the invention the invention discloses a kind of flour improver that does not contain bromate and preparation method thereof, it will be by carrying out composite to oxidants such as human body safety, lower-cost azodicarbonamide, ascorbic acid and enzyme preparation, make the effect of various compositions collaborative each other, to reach effect to the strong muscle of flour oxidation.

Modifying agent provided by the invention, its prescription is as follows:

The CSL of 15-25% (CSL) (unless specified otherwise is arranged, otherwise the percentage composition that occurs in this specification all is weight percentage);

The stearoyl lactate of 5-15% (SSL);

The sodium ascorbate of 10-15%;

The azodicarbonamide of 2-10% (ADA);

The AMS of 2-10%;

The starch of 25-60%.

Above-mentioned raw materials is the extraordinary powdery solid of free-running property, CQ20 number sieve should all stipulating by standard GB 5507.

Normal conditions, this type of modifying agent can directly be mixed with raw material by prescription, but among the present invention, if with common ADA with there is not the ascorbic acid of encapsulated processing directly to mix, oxidation reaction can take place and make ascorbic acid reduce original effect in both, therefore, flour improver of the present invention prepares as follows:

Flour improver is made up of A goods and B goods, does not comprise azodicarbonamide (ADA) in the B goods, does not comprise sodium ascorbate in the A goods;

The A goods are to make after mixing in mixing and blending machine by CSL (CSL), stearoyl lactate (SSL), azodicarbonamide (ADA), AMS and the starch that will be no more than the prescription total amount;

The B goods are to make after mixing in mixing and blending machine by CSL (CSL), stearoyl lactate (SSL), sodium ascorbate, AMS and the starch that will be no more than the prescription total amount;

A goods and B goods are packed respectively, and mutual group becomes flour improver of the present invention;

The consumption of starch is better by prescription total amount mean allocation in A goods and the B goods;

A goods and B goods did not mix before using.

During use, add this flour improver to flour in the addition of 0.03-0.05% (with the percentage of flour weight) in the middle of stirring and evenly mixing get final product.

Compared with prior art, the invention has the beneficial effects as follows significantly, it does not contain bromate, so no longer include in the flour improver bromate to the threat of health; Simultaneously, the present invention compares with other bromate substitute, and cost has reduction significantly; In addition, modifying agent provided by the invention can make Flour product at aspects such as institutional framework and surface smoothness, anxious rising property obvious improvement be arranged.

The specific embodiment

Embodiment one:

A kind of flour improver, its prescription is as follows:

CSL 20g

Stearoyl lactate 10g

Sodium ascorbate 10g

Azodicarbonamide 4g

AMS 5g

Starch 51g

With the CSL (CSL) of 20g, the stearoyl lactate of 10g (SSL) is made the A goods after the 25.5g of the AMS of the azodicarbonamide of 4g (ADA) and 5g and prescription starch total amount mixes in mixing and blending machine;

With the sodium ascorbate of 10g and the starch of other 25.5g, make the B goods after in mixing and blending machine, mixing;

A, B goods are formed flour improver jointly.

Addition according to 0.04% carries out breadmaking in the middle of adding flour improver to high-strength flour, compares with control group, and the bread that has added this flour improver all has a clear superiority at aspects such as institutional framework, surface smoothness, anxious rising property.

Claims
