Embodiment 1
[0024] A preparation method of grape seed proanthocyanidin micropowder, the steps are as follows:
[0025] (1) Dry the grape seeds naturally, remove grape skins and other sundries, dry the grape seeds in a blast drying oven at 30 °C for 3.0 hours, cool them naturally in a desiccator, and pass them through a sieve with a pore size of 0.425 μm after being crushed by a plant grinder. Get the grape seed powder, seal it for later use.
[0026] (2) Weigh 50 g (accurate to 0.01 g) of grape seed powder into a high-pressure PE bag, add 500 mL of distilled water, stir evenly, and perform ultra-high pressure treatment. After the pressure rises to 400 MPa, keep it for 15 minutes. is 10 s, the grape seed powder treated liquid after ultra-high pressure treatment is filtered, and the filtrate is the ultra-high pressure extract of grape seed proanthocyanidins.
[0027] (3) Put the flask containing the ultra-high pressure extract of grape seed proanthocyanidins in a water bath at 45 °C, evacu...

Abstract
The invention relates to a preparation method of natural plant micro powder, and especially relates to a grape seed procyanidine micro powder, and a preparation method and application thereof. The preparation method comprises the following steps: sequentially putting dried and crushed grape seed powder and distilled water into an ultrahigh-pressure PE bag, uniformly stirring, performing ultrahigh-pressure treatment, and filtering a treatment solution to obtain a grape seed procyanidine extract solution; and performing low-temperature concentration and spray drying on the grape seed procyanidine extract solution to prepare the grape seed procyanidine micro powder. The grape seed procyanidine micro-powder prepared by the invention is added into a cigarette filter stick, has no adverse effect on the sensory quality of cigarettes, and can effectively reduce free radicals in mainstream smoke and improve the smoking safety of the cigarettes. The grape seed proanthocyanidins are extracted under ultrahigh pressure at normal temperature, so that the damage to the proanthocyanidins is small, the dissolution rate is high, the consumed time is short, and the preparation efficiency is high. The natural plant micro powder is used for preparing a natural plant micro powder special filter stick, has no adverse effect on the sensory quality of cigarettes, and can effectively reduce free radicals of mainstream smoke and improve the smoking safety of the cigarettes.
Description
technical field [0001] The invention relates to a preparation method of natural plant micropowder, in particular to a kind of grape seed proanthocyanidin micropowder and its preparation method and application. Background technique [0002] Ultra-high pressure is to apply a hydrostatic pressure of 100-1 000 MPa to the extract at room temperature and keep the pressure for a certain period of time, and then quickly release the pressure. The solvent can penetrate into the interior of the solid raw material under the action of ultra-high pressure, so that the active ingredient in the raw material is dissolved in the extraction solvent, and it is kept under a predetermined pressure for a certain period of time. After the active ingredient reaches the dissolution equilibrium, the pressure is released quickly. Under this condition, the active ingredient can quickly diffuse into the extract around the tissue. Compared with other traditional extraction techniques, the ultra-high pres...
