| titleOfInvention | Preparation method of snow pear extract for cigarettes |
| abstract | The invention belongs to the technical field of flavors and fragrances, and provides a preparation method of a snow pear extract for cigarettes, which comprises the following steps: A. cleaning snow pears, peeling, removing kernels, cutting into blocks, adding a pretreating agent, pulping, and performing dehydration treatment to obtain a snow pear pretreatment substance; the pretreating agent is prepared from the following components in a mass ratio of 1-2: 7, ascorbyl palmitate and sorbitol; B. taking half of the mass of the snow pear pretreatment, extracting with ethanol with the volume fraction of 60%, filtering, and concentrating to obtain a first extract; C. taking the other half of the snow pear pretreatment substance by mass, leaching with ethyl propionate, filtering, and concentrating to obtain a second extract; D. and mixing the first extract and the second extract to obtain the snow pear extract for cigarettes. By adopting the technical scheme, the problems of low content of flavonoid compounds and low extraction rate in the snow pear extract obtained by the extraction method in the prior art are solved. |
