Embodiment 1

[0042] A preparation method of microcapsules embedding Pu'er tea essential oil, comprising the following steps:

[0043] (1) Starch hydrolysis:

[0044] Step A: first prepare a waxy cornstarch solution with a mass concentration of 15% using a phosphate buffer solution, stir continuously, heat in a water bath to 90° C. and keep for 35 minutes, so that the starch is fully gelatinized and presents a transparent state;

[0045] Step B: Cool down the gelatinized starch solution in step A to 50°C (including the center temperature of the beaker), add a certain amount of pullulanase with an enzyme activity of 1000U / g, the weight ratio of starch to enzyme is 70:1, Stir for 4 hours to fully hydrolyze the starch;

[0046] Step C: Take the starch solution hydrolyzed in step B in a test tube, centrifuge it on a high-speed centrifuge at 1000r / min for 2 minutes, remove the sediment at the bottom of the test tube (starch and impurities that have not been completely hydrolyzed), take the uppe...

Embodiment 2

[0065] In this example, the method of sensory suction is used to evaluate whether the sustained-release performance of the microcapsules prepared in Example 1, that is, the embedded Pu-erh tea essential oil is improved compared with the un-embedded Pu-erh tea essential oil.

[0066] In the experiment under the same conditions, the microcapsules prepared in Example 1 and the unembedded Pu'er tea essential oil were respectively added to cigarette paper by coating and rolled into cigarettes (addition amount was 0.5%, according to cigarette paper By weight), compared and appraised and sucked and found: the microcapsules prepared in Example 1 can also maintain a strong fragrance after 60 days, but the unembedded Pu'er tea essential oil then disappears after 5 days.

[0067] Therefore, compared with the unembedded Pu'er tea essential oil, the microcapsules of the present invention which embed the Pu'er tea essential oil greatly improves the slow-release property of the Pu'er tea esse...

Abstract

The invention belongs to the technical field of microcapsules and preparation methods thereof, and particularly relates to a microcapsule embedded with Pu'er tea essential oil as well as a preparationmethod thereof and application of the microcapsule in cigarettes serving as an additive. A wall material of the microcapsule is octenyl succinic anhydride-modified amylose, and a core material of themicrocapsule is the Pu'er tea essential oil. The microcapsule has the advantages of high efficiency, good fragrance-lasting effect, simple operation and low cost, and has an obvious improving effecton stability and sustained release of the Pu'er tea essential oil in the application in cigarette. The invention further discloses a Pu'er tea-flavor cigarette containing the microcapsule.

Description

technical field [0001] The invention belongs to the technical field of microcapsules and preparation methods thereof, and in particular relates to a microcapsule embedding Pu'er tea essential oil, a preparation method and application thereof. Background technique [0002] Pu'er tea is mainly produced in Pu'er, Xishuangbanna and other areas of Yunnan Province. It has a long history of cultivation. It has health effects such as fat reduction and blood pressure reduction, anti-aging, stomach nourishing and sterilization. Loved by local and national people. The molecular structure of Pu'er tea essential oil is complex, highly volatile and very unstable. Essence embedding refers to the use of a protective wall material to coat the essence in different processes, so as to endow the essence with a certain degree of anti-evaporation, anti-reaction and anti-dissipation properties during use. Therefore, researching suitable embedding methods for Pu'er tea essential oil and improving...
