Embodiment 1

[0030] Squeeze fresh apricot juice, weigh 1 kg of apricot solid-liquid mixture, add 10 kg of distilled water, soak for 60 minutes, add acid-base buffer solution, adjust the pH value of the aqueous solution to 3.5, and then add 0.5% of the aqueous solution. Gelase, placed in a constant temperature water bath for enzymolysis, the temperature of the water bath is set at 45 ° C, stirring once every 10 minutes during the enzymolysis process, stirring for 5 minutes each time, to ensure that the pectinase can be fully dispersed in the apricot granules, and the apricot pulp The pectin in the medium is continuously enzymatically hydrolyzed, and the enzymatic hydrolysis time is 2h. Then add an acid-base buffer solution to adjust the pH value of the solution, adjust the pH value to 5.8, add neutral protease accounting for 0.5% of the aqueous solution mass ratio, set the constant temperature water bath to 45°C, stir once every 10min during the enzymolysis process, and Stir for 5 minutes t...

Embodiment 2

[0033] Squeeze fresh apricot juice, weigh 1 kg of apricot solid-liquid mixture, add 10 kg of distilled water, soak for 60 minutes, add acid-base buffer solution, adjust the pH value of the aqueous solution to 3.8, and then add 1.0% of the aqueous solution. Gelase, placed in a constant temperature water bath for enzymolysis, the temperature of the water bath is set at 48 ° C, stirring once every 10 minutes during the enzymolysis process, stirring for 5 minutes each time, to ensure that the pectinase can be fully dispersed in the apricot granules, and the apricot pulp The pectin in the medium is continuously enzymatically hydrolyzed, and the enzymatic hydrolysis time is 2h. Then add an acid-base buffer solution to adjust the pH value of the solution, adjust the pH value to 6.5, add neutral protease accounting for 1.0% of the aqueous solution mass ratio, set the constant temperature water bath to 48°C, stir once every 10min during the enzymolysis process, and Stir for 5 minutes t...

Embodiment 3

[0036] Squeeze fresh apricot juice, weigh 1 kg of apricot solid-liquid mixture, add 10 kg of distilled water, soak for 60 minutes, add acid-base buffer solution, adjust the pH value of the aqueous solution to 4.0, and then add 1.5% of the aqueous solution. Gelase is placed in a constant temperature water bath for enzymolysis. The temperature of the water bath is set at 50°C. During the enzymolysis process, stir once every 10 minutes, stirring for 5 minutes each time, to ensure that the pectinase can be fully dispersed in the apricot granules, and the apricot pulp The pectin in the medium is continuously enzymatically hydrolyzed, and the enzymatic hydrolysis time is 2h. Then add an acid-base buffer solution to adjust the pH value of the solution, adjust the pH value to 7.0, add neutral protease accounting for 1.5% of the aqueous solution mass ratio, set the constant temperature water bath to 50°C, stir once every 10min during the enzymolysis process, and Stir for 5 minutes to e...

Abstract

The invention provides an apricot extract for tobaccos and a preparation method of the apricot extract. The preparation method comprises the steps of juicing fresh apricots, weighing a solid-liquid mixture, soaking with distilled water, adjusting a PH (potential of hydrogen) value of an aqueous solution, adding a certain amount of pectinase and neutral proteinase into a mixed solution, putting a whole container in a thermostatic waterbath for enzymolysis, performing suction filtration after the enzymolysis to form filter residue and filtrate for future use, putting the apricot filter residue after enzymolysis in a microwave extraction tank, adding an alcohol aqueous solution for microwave extraction, filtering an extract after the microwave extraction to form extracted filtrate, merging the filtrate and the filtrate after the enzymolysis to form mixed filtrate, and performing decompressed concentration on the mixed filtrate to form the apricot extract for the tobaccos with relative density of 1.20-1.35. The apricots are taken as a raw material; a synergic extraction manner of an enzymolysis method and the microwave extraction is adopted, so that the yield of a total extract of the apricots is increased; and at the same time, the negative effects of cigarette stimulation and taste residue arising from an apricot extract prepared by the conventional reflux extraction method are eliminated.

Description

technical field [0001] The invention relates to the technical field of flavors and fragrances for tobacco, in particular to an apricot extract for tobacco and a preparation method thereof. Background technique [0002] Apricot, Rosaceae Prunus, Latin scientific name: Prunusarmeniaca, is one of the main cultivated fruit tree varieties in northern my country. It is characterized by early maturity, bright color, juicy pulp, sweet flavor, and sweet and sour taste. It is a fruit at the turn of spring and summer. It occupies an important position in the market and is deeply loved by people. [0003] Apricots are native to China and are planted throughout Central Asia, Southeast Asia, and parts of Southern Europe and North Africa. Apricots are widely distributed in my country, except for the southern coast and Taiwan Province, most provinces and autonomous regions have them, including Hebei, Shandong, Shanxi, Henan, Shaanxi, Gansu, Qinghai, Xinjiang, Liaoning, Jilin, Heilongjiang, ...
