Abstract

PURPOSE:To title bleaching agent that contains a raw soybean flour or defatted soybean flour which has reduced water content and lipoxidase activity, thus being used to bleaching wheat flour or the like, because its lipoxidase activity is maintained during storage. CONSTITUTION:In a food bleacher containing raw soybean flour and/or defatted soybean flour having lipoxidase activity, when necessary, cereal flour, starch, protein flour, KONNYAKU (devil tongue) flour and dextrin, the water content is limited to less than 10% to inhibit the deterioration of lipoxidase activity. Thus, it is used as a bleacher which is composed of naturally occurring products.

DETAILED DESCRIPTION OF THE INVENTION The present invention provides raw soybean flour and/or having apoxidase activity.
Alternatively, the present invention relates to a natural food bleaching agent containing defatted soybean flour and preventing a decrease in activity during storage.

Food products in general, especially bread, noodles, gifuza, shumai, steamed buns, etc. made from wheat flour, are
White products are preferred. Conventionally, flour has been bleached by adding a chemical containing benzoyl peroxide as its main ingredient to the flour. However, in recent years, there has been growing public interest in food hygiene problems caused by such additives remaining in food, and nutritional problems caused by additives destroying nutritional components in foods. Chemicals are gradually being phased out. Currently, benzoyl peroxide is not used in wheat flour in Japan, and flour is sold commercially without bleaching.

On the other hand, these products made from unbleached flour,
Steamed steamed buns and the like become yellowish in color and appear to have lost their freshness, so their commercial value drops significantly compared to products made from conventional bleached wheat flour.

Therefore, a major challenge for food processors is to replace the above-mentioned chemicals with natural substances that pose no problems in terms of food hygiene, nutrition, etc. and achieve the same bleaching effect as before.

In addition to its bleaching effect, lipoxidase softens the internal phase of bread (reduces the rate of aging and decreases the amount of bonded whitening) (Food Manufacturer Ingredient Survey, January 1967 issue, pages 11 to 15). ), improved texture in noodles (1973 patent application publication no. 62846)
It is known to have a variety of food improvement effects, such as in the publication No. ``Noodle Manufacturing Method.''

It has been known for a long time that soybeans can be used as food bleaching and other improving agents by utilizing this effect, but it has been difficult to actually implement this on an industrial scale. The reason is,
In order to use soybeans for food bleaching or other food improvement purposes, it is necessary to powder them once, but if you use the powdered soybeans immediately for food bleaching or other food improvement purposes, then If you try to store it, its lipoxidase activity will quickly decrease during storage, so
This is because the bleaching effect and other food improvement effects are also lost, resulting in the disadvantage that the desired food improvement effect is not exhibited when used.

このように、リポキシダーゼ活性が低下した大豆粉の場

In this way, in the case of soybean flour with reduced lipoxidase activity, it is conceivable that by increasing the amount used, it may be possible to achieve bleaching and other food improvement effects on foods.

Furthermore, powdered raw soybeans quickly develop a rancid odor during storage because the lipids contained therein become rancid and cannot be used as food.

For these reasons, in order to use raw soybean flour for the purpose of food improvement, it is necessary to prepare the powder each time it is used, which is extremely time-consuming and uneconomical. Therefore, despite its remarkable bleaching action and other food improvement effects, raw soybean flour has actually been hardly used for purposes such as food bleaching.

On the other hand, it is also possible to use defatted soybeans instead of raw soybeans. In this case, the above-mentioned problems due to modification of lipids do not occur. However, as in the case of raw soybean flour,
In this case as well, there is a drawback that the enzyme activity decreases extremely rapidly when stored in powder form, which has been a major hindrance to its utilization.

Therefore, if these raw soybean flours and defatted soybean flours can be treated to prevent the decrease in lipoxidase activity during storage and to maintain their food bleaching properties even after long-term storage, then these raw soybean flours can be This opens the door to the widespread industrial use of defatted soybean flour as a food bleaching agent. However, until now, no effective means for this purpose has been discovered. For this reason, there has not been much public interest in using raw soybean flour or defatted soybean flour as a food bleaching agent.

As is clear from the sample, the moisture content of all samples is 10%.
When the moisture content is higher than that, the activity decreases significantly, and this tendency becomes more severe the longer the storage period. On the contrary, when the sample moisture content is 10% or less, the activity decreases little (and there is not much difference depending on the length of the storage period.
