Любите мороженное?

Автор: Василина 17-03-2012, 13:53

Любите мороженное? Тогда вам это будет интересно…

• Впервые мороженое появилось около 3000 лет назад в Китае.

• Для охлаждения мороженого в Китае использовали смесь льда с пищевой солью.

• Прообразом современного мороженого можно считать замороженное молоко, которое раньше заготавливали в России.

• В Европу рецепт изготовления мороженого попал благодаря Марко Поло в 1292 г. В Луганске (Украина) изготовили самый длинный в мире рулет из мороженого. Его длина 17 м 97 см. Это достижение внесено в Книгу рекордов Гиннесса.

Опыт 1. Обнаружение лимонной кислоты

Лимонную кислоту обнаруживают в пло¬дово-ягодном мороженом несколькими спо-собами.

• Помещают 1 каплю плодово-ягодного мороженого на универсальную индикаторную бумагу. По изменению окраски индикатора подтверждают кислую реакцию среды.

• Наливают в пробирку 1 мл мороженого и приливают 1 мл насыщенного раство¬ра пищевой соды. Наблюдают появление пузырьков углекислого газа

• Наливают в пробирку 1 мл морожено¬го и приливают 2-4 капли 0,1 н. раствора КМп04. Выпадает бурый осадок оксида мар¬ганца (IV)

Опыт 2. Обнаружение жиров

В пробирку с 1 мл мороженого приливают 1 мл дистиллированной воды и 1 мл хлороформа. Закрывают ее пробкой и встряхивают в течение 1 мин. Несколько капель хлороформного раствора помещают на фильтровальную бумагу (учитывают, что в пробирке хлороформный слой находится внизу). На бумагу дуют или слегка нагревают ее для удаления растворителя. Наблюдают появление жирового пятна.
