Abstract

The invention relates to a process for preparing natural pine needle powder, which uses a freeze-drying method and a micronization method. The process comprises the steps of screening and cleaning fresh pine needles obtained through yearly pruning, freezing the fresh pine needles in a freeze dryer, drying the fresh pine needles, cutting the dried pine needles into small segments 1 to 2 centimeters long, putting the small segments of the pine needles into a micronization machine, grinding the small segments into fine powder or ultrafine powder or even nanometer-sized ultrafine powder according to need, sterilizing and packing ground pine needle powder. The process makes the pine needles into a product easier to absorb by human body by performing scientific reasonable deep processing treatment, fully preserves the nutrient components of the pine needles from being destroyed, improves the absorptivity of the nutrient components of the pine needles, and realizes optimum cell-wall breaking effects. As the ground pine needle powder is sterilized and packed, maximum efficacy is obtained with a minimum taking dose, so that the bioavailability of the pine needles is greatly improved.

Description

A kind of preparation technology of natural pine needle meal

Technical field

The present invention relates to the deep process of natural pine needle, be specifically related to pine needle deep process about pine needle freeze drying and ultramicro grinding.

Background technology

Pine needle is one of the most long-lived in the world plant, is the length of hundred wood.To prevent and cure diseases, and to have a long life has been that history in several thousand is arranged with pine needle for folks of china.Famous traditional Chinese medical science Li Shizhen (1518-1593 A.D.)＜＜Compendium of Materia Medica〉and middle saying: " pine needle is called pine tag, and is nontoxic, warm in nature, can nourish the heart of human body, kidney liver, spleen, lung comprehensively.The beneficial gas of making light of one's life by commiting suicide is promoted longevity." all be to adopt the method that directly is processed into pine needle meal to pine needle at present, pine needle is just processed in simple mode.Want to make pine needle can better bring into play its nutritional labeling, still need carry out deep processing to pine needle.

Summary of the invention

Purpose of the present invention is to remedy deficiency of the prior art, provides a kind of by the deep processing processing scientific and reasonable to pine needle, makes the product that more can be easy to absorption of human body.That is: take cryodesiccated method, carry out micro mist or ultramicro grinding then as required, even the method for nanoscale ultra micro powder.

The present invention has two kinds of processing methods:

One, freeze-drying

1, the bright pine needle that pruned and prune and every year cleans, and puts it into by 0 ℃ to-50 ℃ cryodesiccated method and carries out freeze drying in the freeze drier, is dried to water content and is being advisable below 5%.

The pine needle that above-mentioned drying is good is cut into 1-2 centimetre segment, and then little pine needle section is put into micronizer and carry out micro mist as required, or ultramicro grinding. even nanoscale ultra micro powder.Temperature be subzero 50-0 ℃ all can, but at the bottom of the temperature of still will trying one's best under the possible situation some, the nutritional labeling that can fully preserve pine needle like this is not destroyed, and improves the absorptivity of pine needle nutritional labeling.Be processed into micro mist or ultra micro powder even nanoscale micro mist.Preferably realize the effect of breaking-wall cell, at last the pine needle meal that crushes is carried out sterilization packaging.Thereby obtain the bioavailability that maximum medicine has improved pine needle greatly with the taking dose of minimum.

Because the contained composition of pine needle raw material is worth higher, run off easily and rotten and be difficult to preserve, with freezing method production effect ideal, can satisfactorily resolve this problem, make it can better bring into play the characteristic of pine needle, keep original feature, make the better of nutritive value preservation, the loss of various vitamins reaches very little degree; Have advantages such as rehydration is quick, instant.Pine needle is by freeze drying and take the technology of ultramicro grinding, and can fully preserve original various nutritions of pine needle and vitamin and not be destroyed, and can the more effective utilization that is absorbed by the body.

Two, low temperature drying processing method

Be that the pine needle that will clean is placed in the low temperature drying device, temperature is transferred at 15-60 ℃.Adjust dry temperature according to the dry time of want then.Dry good pine needle moisture is greatly in 5%.

The pine needle that above-mentioned drying is good is cut into 1-2 centimetre segment, and then little pine needle section is put into micronizer and carry out micro mist as required, or ultramicro grinding. even nanoscale ultra micro powder.Preferably realize the effect of breaking-wall cell, at last the pine needle meal that crushes is carried out sterilization packaging.Obtain the maximum efficacy of a drug with the taking dose of minimum, thereby improved the bioavailability of pine needle greatly.

More than two kinds of methods because what adopt is the method for ultramicro grinding, the distribution of its power on raw material is quite even.The setting of hierarchy system, strictness has limited bulky grain, obtains the superfine powder that particle diameter is evenly distributed.Taking dose with minimum is obtained maximum efficacy.

The specific embodiment

A kind of deep processing preparation method of natural pine needle meal can adopt freeze-drying or low temperature drying processing method.Comprise the raw material selection, clean that drying is pulverized, sterilization, packing.Specifically: freezing processing method is the bright pine needle that pruned and prune and every year, adopts the ripe clean Lignum Pini Nodi pine needle more than 6 years or the pinus sylvestris var. mongolica pin that are not polluted, cleans through screening.The cool chamber that pine needle after will cleaning is earlier put into freeze drier carries out freezing, and temperature can be looked dry needs and freely be adjusted between 0 ℃ to-50 ℃.More suitable at-15 ℃ to-25 ℃.And then the dryness storehouse that the pine needle that freezes is put into freeze drier carried out drying, (dry speed is relevant by the freezing temperature of pine needle, freezing temperature is high more, the dry time is just short, the low more so dry time of freezing temperature is also just long more) by cryodesiccated method, pine needle is dried to moisture below 5%, the pine needle after the freeze-drying is natural green.Kept every nutritional labeling of pine needle few to the greatest extent destroyed.Then dried pine needle is cut into 1-2 centimetre segment, then little pine needle section is put in the micronizer, carry out micro mist then as required, or ultramicro grinding, even nanoscale ultra micro powder.Smashing fineness carries out sterilization packaging with the pine needle meal that crushes at last between the 50--2000 order.

The another kind of method of described drying is exactly to take the method for low temperature drying.Be that the pine needle that will clean is placed in the low temperature drying device, temperature is transferred below 60 ℃.Adjust dry temperature according to the dry time of want then, a highest wisdom will be made as temperature about 30 ℃.About 40 minutes just can be dry good.

The moisture of dry back pine needle is greatly in 5%.Then pine needle is cut into about 1-2 centimetre segment, then little pine needle section is put into micronizer, carry out micro mist as required, or ultramicro grinding, even nanoscale ultra micro powder, the fineness of pulverizing can be carried out sterilization packaging with the pine needle meal that crushes at last between the 50---2000 order.
