or active agent for bleaching flour, and more' particularly wheat flour, during the mixing and fermentation period of dough in the process of making bakery products.
' Another object of the invention is the provision of a new and improved means or bleaching agent for decolorizing carotin, a yellow pigment found in vegetables, grains, seeds, plants and the like.
A further object of the invention is the provision of a new and improved agent for bleaching flour, which agent has a nutritive value, is
not injurious to the health of the consumer, and has no detrimental effect on the dough in which it is incorporated or on the bread subsequently baked.
A still further object of the invention is the provision of a new and improved material for use in bleaching flour, that is cheap to manufacture, easily obtained in the raw state, readily applied, and that is efficient and satisfactory in use.
Other and further objects and advantages of the invention will appear from the following description and will be pointed out in the appended claims.
In the bleaching of flour it has been the common practice to bleach the flour at the mills,
thus necessitating bleaching the same in the dry state. The present improvement provides for bleaching under conditions of moderate warmth and moisture during the mixing and baking of the product.
Among processes used prior to this-invention, there were four principal processes commercially employed for bleaching flour and characterized by the use of the following materials:
1. With nitrogen peroxide.
2. With chlorine, containing sometimes a small amount of nitrosyl chloride.
3. With nitrogen trichloride.
4. With benzoyl peroxide.
Each of these processes has certain disadvantages. For example nitrogen peroxide does not bleach the flour to the desired extent. Bleaching with nitrogen trichloride and chlorine is difficult to perform uniformly, A slight overbleach with these chemicals seriously damages the flour and even a normal bleach may cause the flour to deteriorate rapidly in storage.
Treatment of flour with chlorine and nitrogen trichloride does more than merely bleach the flour. The protein or gluten of the flour is oxidized or developed so that the bread obtained from such bleached flour has more volume and a greater grain and texture refinement than is the case with the unbleached flour. These qualities may be helpful to the baker under certain circumstances, but if a small, com-' pact loaf is desired they are detrimental.
The bleaching process using benzoyl peroxide does not affect the baking process to any marked degree, but has the disadvantage that the reagent used (benzoyl peroxide) is mixed with "the flour in such minute amounts that even distribution is difficult. Benzoyl peroxide is also very expensive, and bleaching by ,this method costs several times as much as by the other processes. It has been proposed to use as catalyzers to promote the action of the peroxide either chemicals or enzymes of the oxydase or peroxydase class, and as a result thereof an advantage has been claimed for such known procedure in an increase in the volume of loaves obtained from the same quantity of untreated flour.
The present invention seeks to eliminate these difficulties and complex treatments by the provision of a bleaching agent that is cheap to prepare; that does not affect the flour except to decolorize the yellow carotin therein; that possesses food value; and that may be and preferably is incorporated in the flour when the dough is mixed preparatory to baking the bread, thereby eliminating the time and expense of a separate bleaching operation.
This bleaching agent is entirely of vegetable origin and is probably an enzyme or an enzymelike substance that decolorizes the yellow carotin which gives unbleached flour its characteristic yellowish color, This bleaching agent is deof advantages. In the first place, the use of the above mentioned chemicals, with their disadvantages, is avoided. Secondly, the danger of over-treatment of the flour or dough is nonexistent since the sole active principle or bleaching agent employed is an enzyme obtained from a vegetable source, and the use of an excess of several times the amount necessary to bleach the flour will cause no damage whatever, although, if the soy bean'ls used as the source of the enzymic agent, large excessive amounts will give an undesirable bean flavor. Similarly, the color of the soy bean flour will begin to become noticeable since the bleaching'action operates selectively to whiten the unbleached wheat fiour but does not whiten the bean flour. This is also true as to the flavor and color imparted by other plant material which may be used in lieu of the soy bean. Thi'rdly, the baking characteristics of the flour are not changed. Thus the baker can obtain any further development of his dough and gluten he desires by use of a yeast food, and/or high-speed mixing. The latter is the common practice in this country, and our process is especially adapted thereto. Fourthly, flour can be manufactured and sold unbleached, in which condition it is best fitted to keep well in storage.
The most practical and potent source of this enzymic principle or bleaching agent is the soybean, although it is understood that the invention contemplates the use of an enzymic vegemethod of obtaining this enzymic material in an active state and by a process commercially practicable, is by treating soybeans as follows:
Soak the beans for twelve to forty eight hours in water of approximately room temperature, using enough water to cover the beans at all times. This causes the beans to begin to germinate. At the end of the soaking period, the water is drained ofi and the beans are well washed with two or three changes of fresh water. At this point the beans have swelled to about three times their original size. After draining off the wash water the beans are ground in a mill which reduces them to a paste or sludge. sludge is thoroughly mixed with a cornstarch or corn flour or other cereal flour which has preferably been gelatinized to increase its water absorbing capacity.
The resulting mixture is a rather dry, friable mass. This mass is dried in vacuo at a temperature not exceeding 60 C. in order not to injure the enzyme, and it is then ground to a fine powder.
used which corresponds to two parts of cereal flour and one part of soy-beans by weight before soaking, the resulting preparation will be of such strength that when used in a bread dough to the amount of 1-2% of the flour to be bleached, a practically complete decolorization of the characteristic yellow color of unbleached flour is ob- No precautions for proper use are necessaryi. 3
Other methods of manufacture are quite feasible The. soaked soy-beans (or other source of the enzymic material) may be ground to. a-paste and dried at a low temperature in vacuo, and
If an amount of cereal flour which is to be mixed with the ground soaked soy-beans is then ground'to a powder. By another method, the soaked soy-beans may be ground with additional water, subjected to filtration through cloth to remove the fiber, and the filtrate, which has the appearance of cow's milk, dried at a low temperature and ground to a powder in which dry condition it will not spoil while in storage.
This paste or It should be noted that the drying treatment does not destroy the bleaching principle which is in the filtrate. In lieu of drying the filtrate, the
milk itself may be added directly to the mixture forming a dough batch. The invention is not limited to a specific method of obtaining the active principle, but includes any process by which the active principle, which is apparently an enzyme, may be obtained. A necessary precaution in any method of preparing the product is to keep the temperature at all times below about 60 C. in order that the active principle or enzyme may not be injured or destroyed. The ground material or powder prepared from the beans or equivalent plant source by methods such as those above described, may be designated as bean meal or vegetable fiour.
This bleaching agent is only active in the presence of warmth and moisture, and hence the ground preparation containing it maybe mixed with the flour in a dry state at any time after the flour is made and the mixture stored indefinitely without deterioration. Or the bleaching material may be stirred into the water used to make the dough, or it may be even dumped into the dough mixer on top of the other ingredients before mixing has started, with good results. Extra water should be added to the doi'gh at-the rate of lb. of water for each pound of the powdered material containing the active principle made as described above. This makes the use of the product economical.
The specification discloses the bleaching agent as being best obtained from the soy-bean and as being employed to bleach flour, but these disclosures are by way of example only, and it is understood that it is immaterial from what source the enzyme-like principle or bleaching agent is derived, provided the equivalent plant contains; the enzymic bleaching material which may be used without subjecting the plant to processes more involved than those hreinbefore described. It is also understood that the agent may be used to decolorize carotin in other relations.
Claims specifically directed to the use of the filtrate prepared from the bean -material and sometimes known as bean milk, extract, or the like are presented in our companion application Serial No. 655,858, filed February 8, 1933.
