Недостатками известного способа являются сложность способа и необходимость поддерживать сравнительно низкую температуру 1-10oC при выдержке в течение 20-30 ч.The disadvantages of this method are the complexity of the method and the need to maintain a relatively low temperature of 1-10 o C when holding for 20-30 hours
Известен способ получения концентрата экстракта из порошка стевии, включающий обратную возгонку с ацетоном при 56-58oC в течение 3-5 ч при соотношении сырье: ацетон 1:5-15, удаление ацетона вакуумированием при 25-30oC в течение 0,5-1 ч экстрагирование сырья водой при соотношении сырье:вода 1: 16-30 при 40-60oC в течение 2-6 ч, обработку водного экстракта 96%-ным раствором этилового спирта при 4-6oC в течение 6-8 ч при соотношении экстракт: спирт 1: 5,0-7,73, фильтрование через фильтр-картон в течение 15-30 мин, концентрирование на вакуумно-выпарной установке при температуре 50-65oC до содержания сухих веществ 55-70%, отделение спирта от воды для повторного его использования (см. описание изобретения к авторскому свидетельству СССР N 1794442, МПК A 23 L 1/236, публикация 15.02.93).A known method of obtaining a concentrate of extract from stevia powder, including reverse sublimation with acetone at 56-58 o C for 3-5 hours at a ratio of raw materials: acetone 1: 5-15, removal of acetone by vacuum at 25-30 o C for 0, 5-1 hours extraction of raw materials with water at a ratio of raw materials: water 1: 16-30 at 40-60 o C for 2-6 hours, treatment of the aqueous extract with a 96% solution of ethyl alcohol at 4-6 o C for 6- 8 hours at an extract: alcohol ratio of 1: 5.0-7.73, filtering through filter paper for 15-30 minutes, concentrating on a vacuum evaporator at a temperature round 50-65 o C to a solids content of 55-70%, the separation of alcohol from water for reuse (see the description of the invention to the USSR copyright certificate N 1794442, IPC A 23 L 1/236, publication 02.15.93).
Недостатками известного способа являются его сложность и недостаточная экономичность, обусловленная необходимостью использования 96%-ного раствора этилового спирта при обработке водного экстракта. The disadvantages of this method are its complexity and lack of efficiency, due to the need to use a 96% solution of ethyl alcohol in the processing of an aqueous extract.
Задачей, на решение которой направлено данное изобретение, является упрощение способа и повышение его экономичности. The problem to which this invention is directed, is to simplify the method and increase its efficiency.
Сущность изобретения заключается в том, что в способе получения концентрата экстракта из порошка травы стевии, включающем экстрагирование сырья, фильтрование экстракта и концентрирование на вакуум-выпарной установке, экстрагирование сырья проводят 20-30%-ным раствором этилового ректификованного спирта в соотношении сырье:раствор 1:25-30 в течение 20-30 ч при 18-25oC, фильтрование экстракта проводят на сите с размером ячеек не более 0,3 мм, концентрирование экстракта выполняют при 50-60oC в течение 2-3 ч до содержания сухих веществ 70-80%.The essence of the invention lies in the fact that in the method of obtaining an extract concentrate from stevia herb powder, including extracting the raw material, filtering the extract and concentrating on a vacuum evaporator, extracting the raw material is carried out with a 20-30% ethyl alcohol solution in the ratio of raw material: solution 1 : 25-30 for 20-30 hours at 18-25 o C, filtering the extract is carried out on a sieve with a mesh size of not more than 0.3 mm, the concentration of the extract is carried out at 50-60 o C for 2-3 hours until dry substances 70-80%.
Это позволяет упростить способ и повысить его экономичность. This allows you to simplify the method and increase its efficiency.
Пример 1. Порошок травы стевии экстрагируют 20%-ным раствором этилового ректификованного спирта в соотношении сырье:раствор 1:30 в течение 20 ч при 25oC. Фильтрование экстракта проводят на сите с размером ячеек не более 0,3 мм, при этом осадок отжимают, а экстракты объединяют. Концентрирование экстракта выполняют на вакуум-выпарной установке при 50oC в течение 3 ч до содержания сухих веществ 70%. Готовый концентрат упаковывают по весу в соответствующую тару.Example 1. The herb stevia powder is extracted with a 20% solution of rectified ethyl alcohol in the ratio of raw materials: 1:30 solution for 20 hours at 25 o C. The extract is filtered on a sieve with a mesh size of not more than 0.3 mm, while the precipitate squeeze, and the extracts are combined. Concentration of the extract is performed on a vacuum evaporator at 50 o C for 3 hours to a solids content of 70%. The finished concentrate is packaged by weight in an appropriate container.
Примеры 2 и 3. Способ выполняется аналогично примеру 1 при режимах, указанных в таблице. Examples 2 and 3. The method is performed analogously to example 1 under the modes indicated in the table.
Использование предлагаемого изобретения позволяет упростить способ и повысить его экономичность в 3-4 раза. The use of the invention allows to simplify the method and increase its efficiency by 3-4 times.
