(54) СПОСОБ ПОЛУЧЕНИЯ СУХОГО ЯИЧНОГО БЕЛКА(54) METHOD OF OBTAINING DRY EGG PROTEIN
Изобретение относитс к способам получени порошков из в зких жидкостей, в частнос ти получени белка прн переработке иц, и может быть использовано в пищевой, медицинской и фармацевтической пpoмьщ лeннocти. Известен способ получени ичного порощка включающий концентрирование, диспергирование и сушку распылением 1. Недостатком этого способа вл етс то, что порошок имеет высокую влажность 9%, раство римость не более 90-93%, хранитс до 6 мес цев , имеет большие потери мелкой фракции. Целью изобретени вл етс улучшение качества и увеличение выхода продукта. Дл этой цели концентрирование белка осуществл ют на ацетатцеллюлозных мембранах со .средним диаметром отверстий 03-0,5 мкм, при скорости потока 0,35-0,6 м/сек, давлении 4-5 атм, диспергирование ведут до размера частиц 140-180 мкм, а температуру воздуха в начале сушки поддерживают на уровне 180- 195°С и в конце - 55-65°С, .при этом фракцию высушенного белка с размером частиц менее 15 мкм возвращают в зону распыла противотоком к воздуху. Пример выполнени способа. Яйца раздел ют на желток и белок, затем ичный белок (12% сухих веществ) пропускают под давлением 5 атм через ацётатцеллюлозные мембраны со средним диаметром отверстий 0,5 мкм МО скоростью потока, 0,4 м/сек. Фильтрат, содержащий воду, глюкозу, небольшое количество солей, отвод т как побочный продукт, а концентрировашагй до белок диспергируют до размера частиц 160 мкм и подвергают термообработке в среде нагретого газа прн температуре в начале сушки 190° и в конце 55°С. Мелкую фракщпо порошка с размером частиц менее 15 мкм вновь пневмотранспортером возвращают в зону распыла противотоком к сушильному агенту. При этом получаетс сухой ичный белок влажностью 5,0%, растворимостью и средним диаметром частиц 68 мкм. Функциональные свойства ичного белка, как пенообразовател , сохран ютс на высоком уровне.The invention relates to methods for the preparation of powders from viscous liquids, in particular the production of protein for the processing of eggs, and can be used in food, medical and pharmaceutical fields. The known method of obtaining an egg powder, which includes concentration, dispersion and spray drying. The disadvantage of this method is that the powder has a high humidity of 9%, a solution of not more than 90-93%, is stored for up to 6 months, has large losses of the small fraction. The aim of the invention is to improve the quality and increase the yield of the product. For this purpose, protein concentration is carried out on cellulose acetate membranes with an average hole diameter of 03-0.5 µm, at a flow rate of 0.35-0.6 m / s, a pressure of 4-5 atm, dispersion is carried out to a particle size of 140-180 μm, and the air temperature at the beginning of drying is maintained at 180-195 ° C and at the end 55-65 ° C, while the fraction of the dried protein with a particle size of less than 15 μm is returned to the spray zone countercurrently to the air. An example of the method. Eggs are divided into yolk and protein, then the egg white (12% solids) is passed under a pressure of 5 atm through acetate cellulose membranes with an average orifice diameter of 0.5 µm MO, flow rate, 0.4 m / sec. The filtrate containing water, glucose, a small amount of salts is removed as a by-product, and concentrated to protein is dispersed to a particle size of 160 µm and subjected to heat treatment in a medium of heated gas at a temperature of 190 ° C at the beginning of drying and 55 ° C. Fine powder with a particle size of less than 15 microns is returned by the pneumatic conveyor back to the spray area counter-current to the drying agent. A dry egg protein with a moisture content of 5.0%, solubility and an average particle diameter of 68 µm is obtained. The functional properties of the egg protein, as a blowing agent, are maintained at a high level.

Такой сухой белок можно хранить в неоспаждаемом складе более года.Such dry protein can be stored in a non-decayable warehouse for over a year.
Иснользование предлагаемого способа получени сухого ичного белка обеспечивает по сравнению с существующими способами еледующие преимуицества;The use of the proposed method of obtaining dry egg white protein provides, compared to the existing methods, the following advantages;
- улучщение качества ичного белка и большую стабильность его свойств в процессе хранени ;- improving the quality of egg protein and greater stability of its properties during storage;
-увеличение выхода продукта;-increased product yield;
-снижение себестоимости продукта.-reduction of the cost of the product.
