Abstract

The invention discloses a method for preparing a chamomile extract for tobaccos. The method comprises the following steps: mixing flowers, stem parts and leaves, so as to obtain an extracting raw material; carrying out supercritical CO2 extraction on the extracting raw material, so as to obtain first-stage chamomile isolate and second-stage chamomile isolate; adding the first-stage chamomile isolate to propylene glycol, so as to obtain a mixture; separating and purifying the mixture again by using a molecular distillation technology, so as to obtain a chamomile molecular distillation isolate; mixing the second-stage chamomile isolate with the chamomile molecular distillation isolate, so as to obtain a chamomile mixed liquid; and adding honey to mixed filtrate, and stirring evenly, so as to obtain the chamomile extract for tobaccos. The method is energy-saving, environmental friendly, convenient and fast; the obtained chamomile extract for tobaccos has the effects of lifting the tobacco aroma quality, softening the smoke, increasing the sweet feeling of the smoke and improving the aftertaste; and the application effect in the tobaccos is relatively ideal.

Description
