Abstract
The present invention discloses a pre-processing method of Brasenia schreberi. The pre-processing method is finished according to the following steps: (1) collecting fresh Brasenia schreberi and rinsing the fresh Brasenia schreberi with water; (2) preparing slurry: a slurry preparation method is as follows: pulverizing the fresh Brasenia schreberi with a pulverizer, and then milling the pulverized Brasenia schreberi with a colloid mill to obtain Brasenia schreberi juice, concentrating the juice through a single-effect concentrator at room temperature to a moisture content of 40-60% to obtain the slurry; or the slurry preparation method is as follows: adding the fresh Brasenia schreberi into water with a material ratio of 1-5: 1, and obtaining the slurry by high-speed rotation; and (3), pressing the slurry obtained in step (2) into a centrifugal spray dryer for drying and sterilizing the slurry to obtain dried Brasenia schreberi powder. The Brasenia schreberi is processed into the dried Brasenia schreberi powder so that old leaves and stems of the Brasenia schreberi can also get a reasonable utilization, and bioavailability of the Brasenia schreberi is improved. Shelf life of the obtained dried Brasenia schreberi powder can be extended to two years, and the dried Brasenia schreberi powder is good for processing high added value products. Only 3-4 people are needed to complete the whole process, saving a lot of manpower and material resources.
Description
Technical field
The present invention relates to a kind of pre-process method of water shield.
Background technology
Water shield (water shield, Brasenia schrebei), original perianth subclass Nymphaeceae water shield belongs to perennial fresh water aquatic herbaceous plant, has another name called membranaceous marshmarigold herb, lake dish, water certain herbaceous plants with big flowers or dew certain herbaceous plants with big flowers, is grown in pond, lake and marsh.Being a kind of water plant of Precious, Rare, Endangered, is also first-grade state protection plant, the growing environment special because of it and the high request to water quality purity, only more than 13000 mu, the whole world.Water content in its fresh plant is up to 97%, and long-term preservation is very easily putrid and deteriorated.
Traditional water shield pre-process method is pour in stainless steel framework by fresh water shield, the boiled water putting into 100 degree continues to heat 13 minutes, stirring in frame with wooden rake makes it be heated evenly, (period has 30% pectin to come off) treats that leaf begins to show dark brown just taking the dish out of the pot and pours solid glue in cold water into, within 12 hours, pull leak solid carbon dioxide out to add suitable alimentary acetic acid and make acetic acid water shield, about haveing suffered process need manpower 15 people.(easily pollute, rotten, keeping is difficult) after treatment, the shelf-life of water shield can reach 15 days, and the shelf-life is short, and is unfavorable for the utilization of subsequent development high value added product, as the preparation of water shield extract.And the method often for be the process of water shield tender leaf, Lao Ye and stem are taked at present to the mode of directly throwing away, but in fact by analysis in Lao Ye and stem also containing active ingredients such as a large amount of Zn-ef ficiency, throw away and cause a large amount of wastings of resources.
Summary of the invention
For existing problem, the object of the present invention is to provide a kind of pre-process method that comprehensively effectively can utilize the water shield of water shield.
To achieve these goals, technical scheme of the present invention is: a kind of pre-process method of water shield, is characterized in that: complete in accordance with the following steps:
(1), collect fresh water shield, use clear water drip washing, lessivation does not destroy gel layer;
(2), prepare slurry, the preparation method of slurry is: pulverized by fresh water shield pulverizer, then obtains slurries with colloid mill defibrination, and it is that 40-60% obtains slurry that these slurries are concentrated into water content through single-action thickener normal temperature;
Or the preparation method of slurry is: be added to the water by fresh water shield, water shield is 1-5:1 with the material ratio of water, and High Rotation Speed obtains slurry;
(3), water shield dry powder is obtained by carrying out drying sterilizing in slurry press-in drying machine with centrifugal spray obtained for step (2).
As preferably: in step (1), fresh water shield comprises water shield tender leaf, stem and Lao Ye.Contain a large amount of zinc in Lao Ye and stem, it is made water shield dry powder together, have passed through the drying sterilizing of drying machine with centrifugal spray, can directly take after mixing it with water.Also water shield dry powder water extraction can be obtained Aqueous extracts, then for the preparation of skin care item, and then by the residue after extraction for the preparation of other high value added product, as contained zinc lozenge etc.Make water shield obtain more favourable comprehensive utilization, do not cause the waste of resource.
In such scheme, in step (2), the speed of rotation is 4000-6000rpm, and rotational time is at least 1 hour.Be conducive to like this forming suspendible slurries.
In such scheme: the temperature of step (3) drying is 80-110 DEG C.The effect of abundant drying, sterilization can be played.
In such scheme: the water content of described water shield dry powder is less than 4%.The product water content obtained is few, and the shelf-life can reach 2 years.
The invention has the beneficial effects as follows: water shield is processed into water shield dry powder by the present invention, the Lao Ye of water shield and stem also can reasonably be utilized, improve the bioavilability of water shield, the water shield powder obtained can reach 2 years without the need to any interpolation shelf-life, improve the shelf life of water shield, be conducive to the production and processing of high value added product.Whole process only needs 3-4 people just can complete, and saves a large amount of manpower and materials.
