A kind of instant asparagus powder
Technical field
The present invention relates to natural plant extracts.Be a kind of instant asparagus powder specifically, can be widely used in the raw material of health food and medicine, cosmetics.
Background technology
At present, the asparagus converted products mainly comprises: asparagus preservation product class (primary processed items), asparagus deep processed product class, asparagus health care medical product class.Asparagus preservation product mainly comprises canned asparagus spear, cold storing and fresh-keeping asparagus, quick-frozen asparagus etc., and these are still now main form processing.The amount of asparagus deep processing is very little, such as chewing tablet of asparagus, asparagus beverage, asparagus preserved fruit, asparagus wine, asparagus pickles, asparagus sugar etc.The functional component of asparagus health care medical product class mainly contains flavonoids, rutin, polysaccharide, saponin(e, free amino acid, high activity dietary fiber from asparagus peel etc.They progressively are being used widely in the industries such as health food, medicine, cosmetics, the oral ball of asparagus that the aloof Food Co., Ltd in asparagus oral liquor, Dongshan, Fujian county that produces such as Xianyang Hui Yuan pollution-free food Co., Ltd produces etc.Not carrying out the pharmaceutical production producer that deep processing directly utilizes the asparagus leftover bits and pieces to make has 51, and major product has asparagus capsule, asparagus syrup, asparagus particle, Aspargus Granule, the peaceful sheet of breast etc.The asparagus medicine advances people's clinical testing and practical application, obtained remarkable result, the pure natural antineoplastic of Pharmacuetical Plant of Huaxi Medical Univ. development-Aspargus Granule electuary for example, this medicine has been got permission the font size certification, long-term taking has no side effect, have and improve immune function of human body, antitumor, diuresis, expansion peripheral vessel, strengthen myocardial contraction, improve the effect such as liver function, be applicable to the auxiliary curing of kinds cancer.According to national cancer therapy drug evaluation criterion Aspargus Granule is evaluated, total effective rate is more than 75%.Chinese patent drug asparagus particle is carrying out allowing the patient add simultaneously in the MVP chemotherapy to primary lung cancer, proved and can obviously improve clinical effective rate, cancer kitchen range remission rate, life quality.The peaceful sheet (asparagus sheet) of the breast that Hangzhou produces, the lobular hyperplasia for the treatment of female breast is efficient to reach 83.8%.Yet, effectively utilize fresh asparagus, dried asparagus or old stalk of asparagus, asparagus straws to extract instant asparagus powder for raw material, be a very promising exploration project.
Asparagus has the health-care effect of control cardiovascular and cerebrovascular disease and pre-anti-cancer.Long-term edible asparagus can be improved body's immunity, eliminates human-body fatigue disease, and is all effective in cure to diseases such as hypertension, artery sclerosis, heart disease, hepatitis, cirrhosis, ephritis, oedema, cystitis.Asparagus is in great demand in developed countries such as Japan, the U.S., Canada, European Countries as Dietetic Food for Canceration Precautio very much.
At present, China's application fresh asparagus, dried asparagus or old stalk of asparagus, asparagus straws are that the research of raw material extraction instant asparagus powder also is in the starting stage, find no in this respect the bibliographical information that closes instant asparagus powder and production technology thereof.
Summary of the invention
The purpose of this invention is to provide a kind of instant asparagus powder, effectively utilize fresh asparagus, dried asparagus or old stalk of asparagus, asparagus straws to extract instant asparagus powder for raw material, it is widely used in the industries such as health food, medicine, cosmetics.
Technical scheme of the present invention is to realize by the following method:
1, selects fresh asparagus, dried asparagus raw material, after pulverizer is pulverized, put into ultrasonic extraction tank, add water soaking 10-60 minute of 0.5-20 times of volume, boiled 15-120 minute with supercritical ultrasonics technology, obtain extract;
2, the extract of step 1 is put into vacuum concentration pot Vacuum Concentration to solid content and reach 10-50%, through cooling below 15 ℃ 10-200 minute, centrifuge was centrifugal, obtains concentrated extracting solution;
3, the concentrated extracting solution after step 2 is centrifugal adds the maltodextrin of 0-200% by its dry matter content, and spray-dried tower 140-190 ℃ spray-drying or freeze-drying make instant asparagus powder to moisture≤5%.
In the present invention, in the above-mentioned steps 3, the temperature of spray-drying the best is at 160 ℃.
Among the present invention, the interpolation maltodextrin ratio of indication, dry rear moisture is all calculated by weight percentage.
Raw material of the present invention is except using fresh asparagus, dried asparagus, and also can adopt old stalk of asparagus, asparagus straws is raw material.
The composition asparagus saponin(e, polysaccharide, polyphenol, the flavones that contain in the instant asparagus powder that adopts fresh asparagus to make among the present invention, its content reach respectively 〉=15.0%, 〉=8.0%, 〉=3.0%, 〉=2.0%.
Equally, adopting composition asparagus saponin(e, polysaccharide, polyphenol, flavones in the instant asparagus powder that dried asparagus makes, its content reaches respectively 〉=7.5%, 〉=4.0%, 〉=1.5%, 〉=1.0%.
Characteristics of the present invention be every day the edible asparagus saponin content that contains reach asparagus powder 0.5g 15% or more, can improve immunity, regulate the blood pressure blood fat, the effect of elimination human-body fatigue.
For demonstrating fully good effect of the present invention, utilize all technical of instant asparagus powder to be illustrated, see Table 1-3:

Usage and dosage: the instant asparagus powder 0.5-1.0 of edible asparagus saponin content 〉=15% or more restrains every day 1 time, warm boiled water at every turn.
The specific embodiment
Embodiment 1
1, take fresh asparagus as raw material, after pulverizing, pulverizer puts into ultrasonic extraction tank, then add the water soaking 60 minutes of 1.5 times of volumes, supercritical ultrasonics technology was boiled 60 minutes, obtained extract;
2, extract is put into vacuum concentration pot, Vacuum Concentration to solid content reaches 15%, and through 15 ℃ of coolings 200 minutes, centrifuge was centrifugal, makes concentrated extracting solution;
3, with 160 ℃ of spray-dryings of the spray-dried tower of the concentrate after centrifugal to moisture≤5%, obtain instant asparagus powder.
The content of the composition asparagus saponin(e in the instant asparagus powder of the present invention, polysaccharide, polyphenol, flavones reaches respectively 〉=15.0%, 〉=8.0%, 〉=3.0%, 〉=2.0%.
